Abstract
Description
[0001] This application is a divisional application of the invention patent application with Chinese application number 201680074156.1 (the invention name of the original application is "Choroidal neovascularization inhibitor or drusen inhibitor and its evaluation or screening method", and the application date of the original application is December 16, 2016). Technical Field
[0002] The present invention relates to a medicine for preventing or treating choroidal neovascularization.
[0003] In addition, the present invention relates to a drusen inhibitor and a method for evaluating or screening the drusen inhibitor. Background Art
[0004] Choroidal neovascularization (CNV) is a disease in which new blood vessels form in the choroid in the macula of the fundus. In addition to age-related macular degeneration (AMD), this disease can also be seen in retinal angioid streaks, pathological myopia, ocular histoplasmosis, and choroidal rupture after trauma.
[0005] Since choroidal neovascularization is fragile, blood components may leak out, causing retinal edema and subretinal fluid retention. In addition, bleeding due to rupture of fragile neovascularization may accelerate the progression of impairment that affects vision loss (Non-Patent Document 1).
[0006] For example, angiogenesis inhibitors such as anti-VEGF drugs that inhibit choroidal neovascularization are used to treat choroidal neovascularization in age-related macular degeneration (Non-Patent Document 2).
[0007] AMD is a disease that causes loss of vision due to age-related factors such as obstruction of the macula of the retina. If AMD progresses, objects or linear objects may appear deformed (metamorphopsia), colors may be lost, and the patient may become sensitive to light, which has a significant impact on the quality of life. In addition, if the disease is serious, a portion of the visual field may be lost (central scotoma, etc.), or even blindness may occur (Non-Patent Document 3).
[0008] AMD is roughly classified into wet AMD (exudative AMD) and dry AMD (atrophic AMD) according to characteristic symptoms. Wet AMD is a type characterized by abnormal new blood vessels and the rupture of the new blood vessels. Wet AMD is from the choroidal new blood vessels under the retinal pigment epithelial cells (Retinal Pigment Epithelium; RPE cells), and blood components ooze out from these fragile blood vessels, and cause retinal edema or retention of subretinal fluid. In addition, bleeding due to fragile blood vessel rupture can accelerate the obstacle affecting decreased vision (non-patent literature 1).
[0009] As a treatment method for AMD, angiogenesis inhibitors such as anti-VEGF (Vascular Endothelial Growth Factor) drugs that inhibit angiogenesis are used for wet AMD (Non-Patent Document 2).
[0010] On the other hand, dry AMD is the disease (non-patent literature 4) that diagnoses according to standards such as vision, fundus examination result, image observation result, exclusion criteria, severe degree classification.Now think that a reason is: due to the structure that is called drusen (drusen), cause visual cell disorder (non-patent literature 5).There is a report that some dry AMD has the example that is transferred to wet AMD.

[0019] Another object of the present invention is to provide a drusen inhibitor.
[0020] The use of antibodies targeting VEGF to block new blood vessels is a symptomatic treatment, not to inhibit or improve the behavior of the cells that produce VEGF. In addition, for biological preparations such as antibodies, the longer the treatment period, the higher the medical expenses required. Moreover, for medicines that require intraocular injection, they are highly invasive and impose a heavy burden on patients. Therefore, the industry strongly seeks a low-invasive and economical therapeutic drug for radical treatment of CNV.
[0021] The inventors of the present invention have conducted intensive research to solve the aforementioned problems and have found that by inhibiting the epithelial-mesenchymal transition (EMT) of retinal pigment epithelial cells (RPE cells) using specific nonsteroidal anti-inflammatory agents (NSAIDs), aldose reductase inhibitors, leukotriene receptor antagonists, chemical mediator release inhibitors and thromboxane A2 receptor antagonists, the expression of VEGF in RPE cells can be inhibited, and choroidal neovascularization can be prevented and / or treated, thereby completing the present invention.

[0102] Hereinafter, the present invention will be described in detail.
[0103] [Choroidal neovascularization prevention and / or treatment agent]
[0104] The preventive and / or therapeutic agent for choroidal neovascularization of the present invention contains as an active ingredient at least one selected from the group consisting of zaltoprofen, oxaprozin, teiprenic acid, flufenamic acid, mefenamic acid, sulindac, epalrestat, zafirlukast, amlexanox, serotonin and pharmaceutically acceptable salts thereof.
[0105] In this specification, "choroidal neovascularization (CNV)" refers to the generation, proliferation and / or expansion of new blood vessels from the choroid of the fundus. Although not limited to, the new blood vessels generated from the choroid extend through the layer where Bruch's membrane and / or retinal pigment epithelial cells exist. CNV can be examined by known methods. Although not limited to, CNV can be examined, for example, by fundus angiography using fluorescent pigments such as fluorescein.
[0106] In the present specification, the "retinal pigment epithelial cells (RPE cells)" refer to single-layer cuboidal epithelial cells present under the retina of the eye.
[0107] The inventor of the present invention etc. speculates that the epithelial-mesenchymal transition (EMT) in RPE cells is the main cause of CNV.In this specification, so-called " epithelial-mesenchymal transition (EMT) " refers to the phenomenon that the properties of epithelial cells are lost and the properties of mesenchymal system are obtained in epithelial cells.By removing the intercellular adhesion in epithelial cells, the morphology of cells changes, and obtains motor ability.As the expression of epithelial system markers expressed by epithelial cells is suppressed, the expression of mesenchymal system markers or the secretion of extracellular matrix (ECM) become hyperactive (in this specification, epithelial system markers, mesenchymal system markers and / or ECM are also referred to as EMT markers).
[0108] The inventor of the present invention etc. establishes the following hypothesis for the generation of CNV, and verifies.The inventor of the present invention etc. finds that if by certain external stimulation and produce EMT in RPE cells, then RPE cells can be degenerated and produce drusen.It is believed that the RPE cells peeled off from Bruch's membrane in the process of forming drusen are blocked due to the supply of oxygen and nutrition from the choriocapillary plate just below Bruch's membrane, therefore due to local hypoxia state, VEGF or a part of MMPs (matrix metalloproteinases; Matrix metalloproteinases) secretion hyperactivity.In addition, it is believed that even if it is not reached in the case of forming drusen, EMT will also be produced in RPE cells, thus making the secretion hyperactivity of the interstitial system marker and the extracellular matrix from RPE cells, and VEGF and a part of MMPs secretion hyperactivity.By these MMPs, decomposition and perforation are produced in Bruch's membrane, by VEGF, induce the angiogenesis from choroid.
[0109] Since the new blood vessels are fragile, blood can easily leak out. If the fragile new blood vessels rupture and cause subretinal hemorrhage, it will rapidly cause vision loss and lead to blindness.
[0110] Diseases associated with CNV (ICD10: International Classification of Diseases, 10th edition (revised in 2003)) include, for example, age-related macular degeneration, exudative age-related macular degeneration, drusen, exudative retinitis, polypoidal choroidal vasculopathy (PCV), exudative retinopathy, central serous chorioretinopathy, central serous choroidopathy, hemorrhagic retinal pigment epithelial detachment, proliferative vitreoretinopathy, proliferative retinopathy, serous retinal pigment epithelial detachment, idiopathic choroidal neovascularization, retinal edema, retinal angiogenesis, retinal angiomatous proliferation (RAP), retinal vasculopathy, atrophic age-related macular degeneration, angiogenic maculopathy, soft drusen, myopic choroidal neovascularization, macular degeneration, maculopathy, macular vascular ectopia, macular lesions, etc.
[0111] As a functional effect on these diseases, for example, age-related macular degeneration accompanied by subfoveal choroidal neovascularization can be mentioned.
[0112] In addition, examples of diseases related to CNV (standard disease name ICD10) include myopic choroidal neovascularization and idiopathic choroidal neovascularization.
[0113] As a functional effect on these diseases, for example, choroidal neovascularization in pathological myopia can be mentioned.
[0114] Examples of diseases associated with CNV (standard disease name ICD10) include diabetic macular edema, type 1 diabetic macular edema, type 1 diabetic maculopathy, type 2 diabetic macular edema, type 2 diabetic maculopathy, and diabetic maculopathy.
[0115] Examples of functional effects against these diseases include diabetic macular edema.
[0116] In addition, diseases related to CNV (standard disease name ICD10) include, for example, macular edema caused by retinal vein occlusion, central retinal vein thrombosis, central retinal vein thrombosis, central retinal vein occlusion, macular edema caused by central retinal vein occlusion, retinal vein thrombosis, retinal vein occlusion, etc.
[0117] As a functional effect on these diseases, for example, macular edema associated with retinal vein occlusion can be mentioned.
[0118] As for the classification of age-related macular degeneration (AMD), in addition to the general classification of dry AMD and wet AMD, there are also reports of classification of early AMD, intermediate AMD or late AMD, classification of non-progressive AMD or progressive AMD, etc. Although there is no limitation, as a special type of wet AMD, there is retinal angiomatous proliferation (RAP).
[0119] Although not limited to this, the new blood vessels in CNV may extend in various directions above Bruch's membrane or RPE cells, or may form polypoid new blood vessels under RPE cells, such as polypoidal choroidal vasculopathy (PCV).
[0120] Exudative AMD is known to be associated with subfoveal CNVs. This type of AMD is sometimes divided into three types: classic AMD, PCV, or RAP, each of which can be treated initially.
[0121] In the present specification, any retinal disease that causes CNV is a target of prevention and / or treatment regardless of the classification of the disease.
[0122] Among the classifications of AMD, wet AMD (exudative AMD) in particular causes CNV under the fovea due to bleeding or wetting, and subretinal hemorrhage is often seen around the CNV, so it has a strong correlation with CNV.
[0123] Based on this speculated mechanism of CNV generation, zaltoprofen, oxaprozin, teiprenic acid, flufenamic acid, mefenamic acid, sulindac, epalrestat, zafirlukast, amlexanox, serotonin and their pharmaceutically acceptable salts respectively inhibit the production of VEGF or MMPs related to the occurrence or expansion of CNV by strongly inhibiting the EMT of RPE cells, thereby expecting to fundamentally prevent and / or treat CNV.
[0124] Can be measured or evaluated by known methods to produce EMT or EMT is suppressed. Although not limited, for example, the loss of epithelial traits can be confirmed by measuring the expression of the following epithelial markers. In addition, for example, the interstitial traits can be confirmed by measuring the expression of the following interstitial markers or the secretion of the extracellular matrix (ECM). The expression of genes, the expression or secretion of proteins can be measured by known methods such as microarray, real-time PCR (Polymerase chain reaction; Polymerase chain reaction) method, PCR method, protein blotting (western blot) method, ELISA (enzyme-linkedimmunosorbent assay; Enzyme-linked immunosorbent assay) method, immunohistostaining. In addition, for example, the hyperactivity of motor ability can be measured by known methods such as tissue staining such as Giemsa staining (Giemsa staining), invasion assay (Invasion Assay) method. In addition, for example, the morphological changes of cells can be measured by known methods such as tissue staining such as HE staining.
[0125] The term "prevention" as used herein refers to preventing the onset of a disease or symptom, delaying the onset of a disease, or preventing the recurrence of a disease in an individual.
[0126] The term "treatment" as used herein means alleviating the symptoms of a disease, eliminating the symptoms of a disease, or inhibiting the maintenance of the symptoms of a disease, or inhibiting the progression, aggravation, deterioration or aggravation of the symptoms in an individual.
[0127] In this specification, so-called " suppressing the EMT of RPE cells " refers to suppressing the situation of the proterties of the epithelial system losing in RPE cells, suppressing the situation of obtaining the proterties of the mesenchymal system, or making the situation of the proterties of the mesenchymal system obtained lose. Although not limited, for example, in RPE cells, the EMT of RPE cells can be evaluated by detecting the situation of maintaining the expression of epithelial system markers, suppressing the expression of the mesenchymal system markers, suppressing the expression and / or secretion of ECM, or suppressing the hyperactivity of motor ability.
[0128] Compounds with EMT inhibitory activity of RPE cells (also referred to as EMT inhibitory compounds in this specification) include compounds known to have inhibitory activity on EMT in epithelial cells. EMT inhibitory compounds include nonsteroidal anti-inflammatory agents, aldose reductase inhibitors, leukotriene receptor antagonists, chemical mediator release inhibitors and thromboxane A2 receptor antagonists; from the perspective of exerting a significant EMT inhibitory effect, zaltoprofen, oxaprozin, teipfic acid, flufenamic acid, mefenamic acid, sulindac, epalrestat, zafirlukast, amlexanox, serotrast or their pharmaceutically acceptable salts can be used. From the perspective of the permeability of the blood-retinal barrier (BRB; Blood retinal barrier), EMT inhibitory compounds are preferably compounds with excellent factors related to BRB permeability such as fat solubility. Although not limited, compounds with high fat solubility are excellent in BRB permeability, so even in the case of oral administration that is not directly delivered to the eye, high prevention and high therapeutic effects on retinal diseases can be expected. In addition, from the viewpoint that long-term administration can be performed according to symptoms, the EMT inhibitory compound is preferably a compound with few side effects. As side effects, although not limited, examples include: loss of appetite, diarrhea, stomatitis, indigestion, gastritis, itching, abnormal liver function, etc. From the viewpoint of these BRB permeability and / or side effects, preferably zaltoprofen, oxaprozin, teipfic acid, flufenamic acid, mefenamic acid, sulindac, epalrestat, zafirlukast, amlexanox, serotrast or their pharmaceutically acceptable salts.

[0159] [Drusen Inhibitors]
[0160] The drusen inhibitor of the present invention contains a compound having an epithelial-mesenchymal transition (EMT) inhibitory activity of retinal pigment epithelial cells (RPE cells) as an active ingredient.
[0161] In this manual, so-called " drusen " refers to the deposit that is present in RPE cell below or around RPE cell that also visible increases change along with age for healthy elderly.Histologically, it is the deposition of the polymorphic material in the collagen fiber layer between the basement membrane of RPE cell and Bruch's membrane, and constituent components are the secretion of cell components such as organelles, cell membrane sample residues, non-esterified cholesterol, complement, RPE cell etc.The deposit that forms the macula of drusen has the basement membrane deposit (basal laminar deposit) that is present in the basement membrane inboard of RPE cell and the basal line deposit (basal linear deposit) that is present in the outside under the electron microscope.
[0162] One theory holds that, for humans, drusen can be classified into hard drusen (less than 63 μm) and soft drusen (more than 63 μm) based on the results of funduscopy. If soft drusen fuse, it is called confluent drusen. When drusen fuse and expand to cause retinal pigment epithelial detachment (PED), it is called drusenoid PED. In addition, in recent years, it has been reported that pseudodrusen, which is classified as another type of drusen, can affect prognosis, and is therefore clinically important. In this specification, "drusen" includes not only hard drusen and soft drusen, but also pseudodrusen and other deposits or structures similar to drusen.
[0163] The diagnostic criteria of AMD in Japan include soft drusen (more than 63 μm) and RPE cell abnormalities as precursor lesions. In the past, the formation mechanism of drusen was not known, and it was difficult to prevent or treat fundamentally. When completing the present invention, the inventors of the present invention etc. obtained the following new insights: drusen is a structure produced by RPE cells causing EMT.
[0164] The inventors of the present invention predict that epithelial cells headed by RPE cells will change their properties due to external stimuli such as aging, UV (Ultra Violet; ultraviolet) light, and obtain properties (referred to as interstitial properties) such as the acquisition of hypersecretion and motor ability of the extracellular matrix. It is strongly inferred that drusen is generated by the property conversion of the retinal pigment epithelial cells produced in the macula.
[0165] Therefore, the inventors used a retinal pigment epithelial cell line (ARPE-19) and confirmed that the cells acquired traits such as hypersecretion of the extracellular matrix and acquisition of motility based on the transformation of their traits, and ultimately formed aggregates (also called "Focus") equivalent to drusen composed of cellular components and their secretions. While verifying the mechanism of its occurrence, they obtained confirmation that the drusen-like structure (aggregate (Focus)) generated in the same process is equivalent to the drusen produced in a living body.
[0166] In the present specification, the so-called "drusen inhibition" refers to reducing the number of drusen formed or decomposing the drusen formed, or reducing the size of the drusen formed (which can be appropriately specified according to the diameter, area, volume, etc.) or preventing the increase, and also includes preventing the formation of new drusen. Although not limited, in the case of reducing the number of drusen formed, for example, compared with a control not treated with a drug, the number of drusen is reduced by at least 5%, preferably by more than 10%, more preferably by more than 20%, particularly preferably by more than 30%, and most preferably by more than 40%. The number of drusen can be evaluated by a known method, for example, using a fundus photograph. In addition, although not limited, in the case of reducing the size of the drusen formed or preventing the increase, for example, compared with a control not treated with a drug, at least the size of the drusen does not change, preferably by more than 5%, more preferably by more than 10%, more preferably by more than 20%, particularly preferably by more than 30%, and most preferably by more than 40%. The size of drusen can be evaluated by known methods, for example, fundus photographs, spectral domain optical coherence tomography (SD-OCT) examination results, fluorescent fundus angiography using fluorescein or indocyanine green, etc. In addition, although not limited, in the case of preventing the formation of new drusen, for example, compared with a control not treated with a drug, the formation of at least 5% or more of new drusen is prevented, preferably 10% or more, more preferably 20% or more, particularly preferably 30% or more, and most preferably 40% or more. The formation of new drusen can be evaluated by known methods, for example, fundus photographs, fluorescent fundus angiography, etc. The evaluation method for drusen inhibition is not particularly limited as long as it can be appropriately evaluated, and preferably a comprehensive evaluation is performed based on the number, thickness, and volume of drusen.
[0167] The formation of drusen is related to the progression of AMD, that is, the reduction of visual field or vision. One theory reports that the increase in the number of drusen on the retina and the progression and size of each drusen lead to the progression of dry AMD, and symptoms such as map-like atrophy are observed. In addition, with the formation of drusen, new blood vessels are generated in the choroid under the drusen, and retinal edema and subretinal fluid retention characteristic of wet AMD can be seen. There are reports that the new blood vessels are fragile, and if they rupture, there are cases where AMD is transferred from dry AMD to wet AMD.
[0168] In addition, it is known that VEGF (vascular endothelial growth factor), which is an inducing factor for neovascularization, and VEGFR (vascular endothelial growth factor receptor), which is a VEGF receptor, are expressed more frequently when cells undergo EMT. However, based on the new insight that drusen formation in dry AMD is caused by EMT, it is speculated that the formation of drusen in dry AMD will also induce neovascularization.
[0169] Therefore, it is believed that the inhibition of drusen is related to the prevention and treatment of wet AMD in addition to dry AMD, and is also related to the prevention and treatment of angiogenesis in dry AMD, which is the pre-stage of transition to wet AMD.
[0170] In addition, the inventors of the present invention have established the following hypothesis: one of the reasons for the very slow development of AMD is the balance between the newly generated drusen and the decomposed (inhibited) drusen. Below, it will be specifically described. Even if it is a healthy person, drusen will be generated due to age increase change, and since decomposition (inhibition) is dominant, during the period of maintaining this equilibrium relationship, the development of AMD is not easy. However, if this equilibrium relationship is unbalanced, the generation of drusen is dominant than decomposition (inhibition), and drusen slowly remains, the development of AMD. The inventors of the present invention speculate that the main factor that strongly affects this equilibrium relationship is EMT. That is, for healthy people, since EMT is suppressed, RPE cells maintain the original epithelial properties, but if the hyperactivity of EMT is dominant due to age increase or external stimulation, RPE cells lose the epithelial properties and become the properties of the interstitial system. As shown in the embodiment described later, in the RPE cells that have obtained the properties of the interstitial system, the generation of ECM such as collagen as the constituent elements of drusen is hyperactive. On the other hand, in organisms, although these ECMs are decomposed by degrading enzymes MMP (matrix metalloproteinases), the expression of TIMP (tissue inhibitors of metalloproteinases; tissue inhibitors of metalloproteinases) that inhibit the activity of MMP due to the hyperactivity of EMT is also hyperactive. By suppressing the activity of MMP, ECM is not decomposed, and the decomposition of drusen is suppressed. As a result, drusen is hyperactive due to the hyperactivity of EMT, causing AMD to develop.
[0171] In addition, by inhibiting EMT, the expression of ECM such as collagen, which is a component of drusen, is inhibited, and the expression of TIMP is inhibited, so that the activity of MMP and the like is significantly expressed, and the decomposition of ECM is promoted. As a result, the generation of drusen is inhibited, and the development of AMD is inhibited, and the cure of AMD caused by the significant decomposition of drusen can be expected. The inventors of the present invention speculate that in the organism, due to the hyperactivity of EMT, the inhibitory mechanism caused by TIMP plays a role, so that the generation of drusen becomes dominant, and the condition of AMD slowly develops.
[0172] Based on this inferred mechanism of AMD development, the overexpression of factors related to the traits of the mesenchymal system can be inhibited by using external factors to inhibit EMT, and / or the mechanism of decomposing drusen in the organism can be fully exerted to improve the balance between the generation and decomposition of drusen. The inventors of the present invention have established a cell model that can reproduce drusen in an organism, and used the cell model to evaluate and screen compounds that inhibit EMT, and also verified whether the compound can inhibit drusen.
[0173] As the classification of AMD, in addition to the general division of dry AMD and wet AMD, the classification of early AMD, intermediate AMD or late AMD, the classification of non-progressive AMD or progressive AMD, etc. are also reported. In this specification, as long as it is AMD related to the onset and aggravation of drusen, it becomes the object of prevention and / or treatment regardless of which classification it is.
[0174] The classification of early AMD, intermediate AMD or late AMD is advocated by the NIH (National Institutes of Health) (refer to NIH Eligibility Categories: A Randomized, Placebo-Controlled, Clinical Trial of High-Dose Supplementation With Vitamins C and E, Beta Carotene, and Zinc for Age-Related Macular Degeneration and Vision Loss Arch Ophthalmol. 2001 October; 119(10): 1417-1436). This classification classifies AMD into no AMD (category 1), early AMD (category 2), intermediate AMD (category 3a, category 3b), and late AMD (category 4a, category 4b) based on the size of drusen in one eye, the area of drusen, and pigment abnormalities, and the symptoms of the other eye.
[0175] No AMD (Class 1) means that there are no drusen in one eye or the size of drusen is small (less than 63 μm), the area of drusen is a circle with a diameter of less than 125 μm (5 to 15 drusen), there is no pigment abnormality, and the same symptoms are present in the other eye. According to this classification, since drusen are produced even in No AMD (Class 1), they can be the subject of prevention and / or treatment using the drusen inhibitor of the present invention.
[0176] For early AMD or intermediate AMD, which is classified as a symptom in which the size and area of drusen further increase, it is estimated that the drusen inhibitor of the present invention will be more effectively used.
[0177] Based on the new understanding that drusen are structures generated by RPE cells inducing EMT, it is understood that drusen can be suppressed by inhibiting EMT in RPE cells.
[0178] As previously mentioned, the compound with the EMT inhibitory activity of RPE cells (also referred to as EMT inhibitory compound in this specification) includes a compound known to have the inhibitory activity to EMT in epithelial cells. As the compound for suppressing EMT in RPE cells, the compound for observing EMT inhibition is also included in the EMT induction model newly found in the present invention, using RPE cell strain.
[0179] Although not limited, the EMT-inhibiting compound may be an agent that inhibits the expression of a mesenchymal lineage marker or an extracellular matrix (ECM).

[0193] [Combination use with angiogenesis inhibitors]
[0194] The present invention provides a preventive and / or therapeutic agent for AMD comprising a combination of an angiogenesis inhibitor and the drusen inhibitor of the present invention.
[0195] In this specification, the so-called "angiogenesis inhibitor" refers to an agent having an effect of preventing angiogenesis, an agent having an effect of preventing angiogenesis from worsening, or an agent having an effect of reducing or eliminating the formed new blood vessels. As angiogenesis inhibitor, there is no limitation, and examples thereof include: anti-VEGF antibody or a fragment of the VEGF antibody (Fab fragment, single-chain variable region fragment (scFv), etc.), a fusion protein of a fragment of the anti-VEGF antibody and the Fc region of the IgG molecule, and an anti-angiogenesis aptamer (RNA aptamer, etc.). Angiogenesis inhibitors can also use known angiogenesis inhibitors that are already on the market, and there is no limitation, for example, examples thereof include: bevacizumab (Avastin (registered trademark)), ranibizumab (Lucentis (registered trademark)), aflibercept (Eylea (registered trademark)), pegaptanib sodium (Macugen (registered trademark)), ESBA-1008, Lampalizumab, MC-1101, doxycycline hydrochloride (Doxycycline Hyclate), and amitraz hydrochloride. Specifically, the aforementioned EMT-inhibiting compound and angiogenesis inhibitor can be used in appropriate combination in consideration of the patient's symptoms and condition, the expected therapeutic effect, and the like.
[0196] About AMD, it is known that angiogenesis occurs in the choroid under the formed drusen, and it is inferred that the angiogenesis under the drusen is inhibited and interacts with the inhibition of drusen, and obtains the prevention and treatment effect of excellent AMD. As the classification of angiogenesis in AMD, wet AMD, early stage and / or mid-term AMD can be exemplified. About early stage and / or mid-term AMD, it is inferred that except the quantity or size increase of drusen, fragile new blood vessels are also generated. In addition, about dry AMD, it is inferred that angiogenesis can also be induced when drusen is produced. Due to the exudation of blood components from this fragile new blood vessel, or the rupture of fragile blood vessels, the transfer to wet AMD can be rapidly carried out. In addition, it is believed that it is important to preventively treat from the early stage AMD that will produce tiny fragile blood vessels. Therefore, in the present invention, drusen inhibitor is by using with angiogenesis inhibitor, is preferably used for the prevention and / or treatment of wet AMD, more preferably used for the prevention and / or treatment of mid-term AMD, further preferably used for the prevention and / or treatment of early stage and / or mid-term AMD.
[0197] By using the drusen inhibitor of the present invention as a combined drug, the dosage, dosing interval, and dosing frequency of the angiogenesis inhibitor can be suppressed, and medical economic effects can be expected.
[0198] In addition, in one embodiment, the drusen inhibitor of the present invention can be used in combination with photodynamic therapy (PDT) for treatment. In photodynamic therapy, drugs such as Verteporfin that selectively transfer to new blood vessels are used, but it is known that laser irradiation will more or less cause damage to the normal choroid. Therefore, by reducing the dosage of drugs such as Verteporfin in photodynamic therapy, or reducing the irradiation time and irradiation amount of the laser, and using the drusen inhibitor of the present invention, effective prevention and / or treatment of AMD can be performed.
[0199] In addition, in one embodiment, the drusen inhibitor of the present invention may be used for the prevention and / or treatment of AMD by appropriately combining an angiogenesis inhibitor with photodynamic therapy.
[0200] The EMT induction model using RPE cells described in the item [EMT induction model] shows the same characteristics as drusen of AMD in terms of gene expression, protein secretion, motility, aggregate formation, etc., and can therefore be effectively used as a cell model of AMD.

[0462] Test Examples 4 to 8 represent tests on the prevention and / or treatment of drusen.
[0463] [Test Example 1: Construction of EMT cell model]
[0464] Experimental Example 1-1: Study on the induction conditions of EMT in RPE cells
[0465] The inventors conducted an experiment to stimulate RPE cells (retinal pigment epithelial cell line: ARPE-19, the same below) under 10 conditions using cytokines or growth factors (TNF-α / IL-1β / TGF-β), and found that significant EMT induction was induced. It is believed that the EMT-induced cell model using cytokines or growth factors reflects the inferred EMT induction mechanism of patients with CNV.
[0466] The 10 conditions are as follows.
[0467] (1) TNF-α 100 ng / mL
[0468] (2) IL-1β 100 ng / mL
[0469] (3) IL-1β 20 ng / mL

[0477] Experimental Example 1-2: Verification of EMT by Expression Changes of EMT Marker Molecules
[0478] RNA was extracted from stimulated RPE cells and expression changes were verified.
[0479] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 1-1, and after 48 hours of EMT induction, cells were recovered. The recovered cells were washed with PBS, 350 μL of RLT buffer (QIAGEN company) was added, and RNA collection was lysate was made. Using RNeasy micro kit (QIAGEN company #74004), total RNA was extracted from the lysate, and SuperScript III First-Strand Synthesis SuperMix (Invitrogen company #11752-250) for qRT-PCR was used to make cDNA from the RNA 2 μg obtained. Using the obtained cDNA 50ng as a template, real-time PCR (ABIPrism 7500 sequence detection system) was performed according to the manufacturer's draft, and the expression of the mRNA of each gene was quantitatively analyzed. Specific primers for each gene were purchased from Invitrogen company. The Ct (Threshold Cycle) value of each gene was normalized by the intrinsic control and the ratio relative to the untreated sample was calculated. The results are shown in Figure 1 .
[0480] like Figure 1 A and Figure 1 As shown in Figure B, the expression of E-cadherin, a marker of epithelial lineage, was decreased in stimulated RPE cells ( Figure 1 A), the expression of N-cadherin, a mesenchymal marker, was upregulated ( Figure 1 B in the figure). This cadherin conversion is a representative phenomenon of EMT. In addition, the mesenchymal marker represented by fibronectin ( Figure 1C) and the hyperregulation of EMT-related transcription factors (Snail, Slug, ZEB1) ( Figure 1 E to Figure 1 G in the figure) and the expression of ECM represented by type I collagen (COL1A1) is increased ( Figure 1 D) Induction of EMT in RPE cells was confirmed by stimulation.
[0481] Test Example 1-3: Verification of temporal changes in EMT marker expression using microarray The EMT induction state at this point in the EMT induction time was analyzed.
[0482] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 1-1, and cells were recovered after 1 hour, 4 hours, 12 hours, 24 hours, 48 hours, and 72 hours of EMT induction. The recovered cells were washed with PBS, 350 μL of RLT buffer was added, and RNA was collected and lysate was made. Using RNeasy micro kit (QIAGEN company #74004), total RNA was extracted from the lysate, and fluorescent labeling was performed using Low InputQuickAmp calibration kit (Agilent Technologies company #5190-2305). Labeled cRNA was hybridized using a human whole genome oligo DNA microarray kit (Agilent Technologies company #G4112F) and in accordance with the protocol specified by the manufacturer. The hybridized slides were cleaned using the Gene Expression Wash Pack (Agilent Technologies #5188-5327) and scanned using the Agilent microarray scanner (Agilent Technologies #G2505B). The scanned images were digitized using Feature Extraction software version 9.5.1 (Agilent Technologies). The numerical data were normalized using the Grobal normalization method. The results are shown in Figure 2 .
[0483] like Figure 2 As shown, the peak of the decrease or increase of EMT markers was 12 hours or 72 hours after EMT induction depending on each gene. Although there were variations, the decreased epithelial markers and the increased mesenchymal markers and ECM were as follows.
[0484] As epithelial markers decreased by EMT induction, ID1, ID2, MUC1, cytokeratin 18 (KRT18), THBS1, VIL2, and E-cadherin (CDH1) were confirmed. In addition, a decrease in TGFB2, a growth factor, was confirmed.
[0485] As mesenchymal markers and ECMs that are hyperregulated due to EMT induction, TWIST1, VIM, CD44, ZEB1, RDX, MMP9, FN1, RHOA, ZEB2, MMP2, TJP1, CTNNB1, MMP3, ETS1, SNAI1, SNAI2, HAS2, SERPINE1, CDH2, MSN, TCF3, SDC1, ITGAV, COL1A1, and SPARC were confirmed. In addition, the hyperregulation of growth factors FGF1, FGF2, and TGFB1 was confirmed.

For RPE cells, EMT was induced under the conditions described in Test Example 1-1, and each compound (oxaprozin, epalrestat, zafirlukast, amlexanox, zaltoprofen) was added at the same time. After 48 hours of EMT induction, the cells were recovered. As a control, a sample without the addition of the evaluation compound (tested agent) was used. The recovered cells were washed with PBS, 350 μL of RLT buffer was added, and RNA was collected and dissolved. Each compound was used at the following concentrations. Oxaprozin: 300 μM, epalrestat: 30 μM, zafirlukast: 3 μM, amlexanox: 30 μM, zaltoprofen: 30 μM. Total RNA was extracted from the lysate using the RNeasy micro kit (QIAGEN #74004), and cDNA was prepared from 2 μg of RNA using SuperScript III First-Strand Synthesis SuperMix (Invitrogen #11752-250) for qRT-PCR. 50 ng of the obtained cDNA was used as a template, and real-time PCR (ABI Prism 7500 sequence detection system) was performed according to the manufacturer's protocol to quantitatively analyze the expression of mRNA of each gene. Specific primers for each gene were purchased from Invitrogen. The Ct (Threshold Cycle) value of each gene was normalized by an intrinsic control, and the ratio relative to the non-treated sample was calculated. The results are shown in Figures 3 to 7 .

[0524] like Figures 8 to 12 As shown, 5 compounds (flufenamic acid aluminum, mefenamic acid, sulindac, teipfic acid, serotonin) also showed a significant inhibition of the expression of EMT markers during EMT induction. These compounds inhibit the generation of VEGF and the like associated with the generation or expansion of CNV by significantly inhibiting EMT, and it is believed that CNV can be fundamentally prevented and / or treated.
[0525] Experimental Example 2-3: Changes in VEGF expression 1
[0526] The VEGF inhibitory effects of the three compounds (oxaprozin, epalrestat, and zaltoprofen) were evaluated using the aforementioned cell model.
[0527] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 1-1, and oxaprozin (Cmax: 340.9 μM), epalrestat (Cmax: 12.2 μM), or zaltoprofen (Cmax: 20.4 μM) were added at the same time. After 48 hours of EMT induction, the cells were recovered. Each compound was added at a concentration of 1 / 2 of Cmax and 1 / 4 of Cmax. As a control, a sample to which the evaluation compound (tested agent) was not added was used. The recovered cells were washed with PBS, 350 μL of RLT buffer was added, and RNA was collected and dissolved. Total RNA was extracted from the lysate using the RNeasy micro kit (QIAGEN #74004), and cDNA was prepared from 2 μg of the obtained RNA using SuperScript III First-Strand Synthesis SuperMix for qRT-PCR (Invitrogen #11752-250). Using 50 ng of the obtained cDNA as a template, real-time PCR (ABIPrism 7500 sequence detection system) was performed according to the manufacturer's protocol to quantitatively analyze the expression of mRNA of each gene. Specific primers for each gene were purchased from Invitrogen. The Ct (Threshold Cycle) value of each gene was normalized by an intrinsic control, and the ratio relative to the non-treated sample was calculated. In addition, a significant difference test (Student t test) was performed for each result, and "*" was marked when p < 0.05, and "**" was marked when p < 0.01. The results are shown in Figures 13 to 15 .
[0528] like Fig.13 As shown in Figure 2, in RPE cells, VEGF mRNA expression is increased due to the induction of EMT. Oxaprozin inhibits the increased expression of VEGF in a concentration-dependent manner. A significant VEGF inhibitory effect was also observed at a concentration of 1 / 4 of Cmax ( Fig.13 A in the figure). The expression of fibronectin, Snail, and vimentin, which are mesenchymal markers, is increased due to the induction of EMT. Oxaprozin inhibited the increased expression of these mesenchymal markers in a concentration-dependent manner (respectively Fig.13 B to Fig.13 D).
[0529] like Fig.14 As shown in Figure 2, in RPE cells, VEGF mRNA expression is increased due to the induction of EMT. Epalrestat inhibits the increased expression of VEGF in a concentration-dependent manner ( Fig.14A in the figure). Fibronectin, Snail, and vimentin, which are mesenchymal markers, are expressed at elevated levels due to the induction of EMT. Epalrestat inhibits the elevated expression of these mesenchymal markers in a concentration-dependent manner (respectively Fig.14 B to Fig.14 D).
[0530] like Fig.15 As shown in Figure 2, in RPE cells, VEGF mRNA expression is increased due to the induction of EMT. Zaltoprofen inhibits the increased expression of VEGF in a concentration-dependent manner. A significant VEGF inhibitory effect was also observed at a concentration of 1 / 4 of Cmax ( Fig.15 A in the figure). Fibronectin, Snail, and vimentin, which are mesenchymal markers, are expressed at elevated levels due to the induction of EMT. Zaltoprofen concentration-dependently inhibited the elevated expression of these mesenchymal markers (respectively Fig.15 B to Fig.15 D).
[0531] according to Figures 13 to 15 , 3 compounds (oxaprozin, epalrestat, zaltoprofen) by significantly inhibiting EMT, and show the situation of suppressing the hyperexpression of mRNA expression of VEGF. These compounds can fundamentally prevent and / or treat CNV because they can suppress the VEGF that is hyperexpressed due to EMT. In addition, according to these results, it is believed that zafirlukast or amlexanox, which can significantly inhibit EMT, can also inhibit VEGF, and fundamentally prevent and / or treat CNV.
[0532] Reference Test Example 2-4: Changes in VEGF expression 2
[0533] Regarding NSAIDs different from oxaprozin and zaltoprofen, etodolac (Cmax: 42.5 μM) and indomethacin (Cmax: 2.79 μM) were evaluated for their VEGF inhibitory effects by the same method as in Test Example 2-3 using the aforementioned cell model. The results are shown in Fig.16 or Fig.17 .
[0534] like Fig.16 As shown in Figure 2, in RPE cells, VEGF mRNA expression was increased due to the induction of EMT. However, etodolac did not inhibit the increased expression of VEGF ( Fig.16 A in the figure). Fibronectin, Snail, and vimentin, which are mesenchymal markers, were expressed at elevated levels due to the induction of EMT. However, etodolac did not inhibit the elevated expression of these mesenchymal markers. No significant differences were observed under all conditions (respectively Fig.16 B to Fig.16 D).
[0535] like Fig.17 As shown in Figure 2, in RPE cells, VEGF mRNA expression was increased due to the induction of EMT. However, indomethacin did not inhibit the increased expression of VEGF ( Fig.17 A in the figure). The expression of fibronectin, Snail, and vimentin, which are mesenchymal markers, was increased due to the induction of EMT. However, indomethacin did not inhibit the increased expression of these mesenchymal markers. No significant differences were observed under all conditions (respectively Fig.17 B to Fig.17 D).
[0536] Based on the results of etodolac and indomethacin, it is speculated that compounds that cannot inhibit the EMT of RPE cells cannot inhibit the hyperexpression of VEGF and are therefore ineffective for the prevention and / or treatment of CNV.
[0537] Experimental Example 2-5: Changes in VEGF expression 3
[0538] The VEGF inhibitory effect of the three compounds (aluminum flufenamate (Cmax: 27.91 μM), mefenamic acid (Cmax: 38.54 μM), and serostat (Cmax: 31.03 μM)) was evaluated using the aforementioned cell model. The VEGF inhibitory effect was evaluated using the aforementioned cell model in the same manner as in Experimental Example 2-3. The results are shown in Figures 18 to 20 .
[0539] like Fig.18 As shown in Figure 2, in RPE cells, VEGF mRNA expression is increased due to the induction of EMT. Flufenamic acid aluminum inhibits the increased expression of VEGF in a concentration-dependent manner. A significant VEGF inhibitory effect was also observed at a concentration of 1 / 4 of Cmax ( Fig.18 A in the figure). Fibronectin, Snail, and vimentin, which are mesenchymal markers, are overexpressed due to the induction of EMT. Flufenamic acid aluminum inhibits the overexpression of these mesenchymal markers (respectively Fig.18 B to Fig.18 D).
[0540] like Fig.19 As shown in Figure 2, in RPE cells, VEGF mRNA expression is increased due to the induction of EMT. Mefenamic acid inhibits the increased expression of VEGF in a concentration-dependent manner. A significant VEGF inhibitory effect was also observed at a concentration of 1 / 4 of Cmax ( Fig.19 A in the figure). Fibronectin, Snail, and vimentin, which are mesenchymal markers, are overexpressed due to the induction of EMT. Mefenamic acid inhibits the overexpression of these mesenchymal markers (respectively Fig.19 B to Fig.19 D).
[0541] like Fig. 20 As shown in Figure 2, in RPE cells, VEGF mRNA expression is increased due to the induction of EMT. Setrolast inhibits the increased expression of VEGF in a concentration-dependent manner. A significant VEGF inhibitory effect was also observed at a concentration of 1 / 4 of Cmax ( Fig. 20 A in the figure). Fibronectin, Snail, and vimentin, which are mesenchymal markers, are overexpressed due to the induction of EMT. Setrolast inhibits the overexpression of these mesenchymal markers (respectively Fig. 20 B to Fig. 20 D).
[0542] like Figures 18 to 20 As shown, 3 compounds (flufenamic acid aluminum, mefenamic acid, serolast) by significantly inhibiting EMT, and show the situation of suppressing the hyperexpression of mRNA expression of VEGF. These compounds are owing to being able to suppress the VEGF that is hyperexpressed due to EMT, it is inferred that CNV can be fundamentally prevented and / or treated. These compounds are owing to being able to suppress the VEGF that is hyperexpressed due to EMT, and therefore can fundamentally prevent and / or treat CNV. In addition, according to these results, it is believed that zafirlukast or amlexanox that can significantly suppress EMT can also suppress VEGF, and fundamentally prevent and / or treat CNV.
[0543] [Test Example 3: In vivo model test for evaluating CNV inhibition]
[0544] It is known that laser irradiation of the mouse fundus induces choroidal angiogenesis and EMT (reference: Ishikawa, et al., Exp Eye Res. 2016 Jan; 142: 19-25). Therefore, the inhibitory effects of zaltoprofen on CNV and EMT were evaluated using a mouse laser irradiation model.
[0545] A zaltoprofen suspension was prepared by stirring 0.15 g of zaltoprofen (manufactured by Tokyo Chemical Industry Co., Ltd.) and 0.75 g of gum arabic (manufactured by Wako Pure Chemical Industries, Ltd.) in 60 mL of water. A vehicle (Vehicle) was prepared by dissolving 0.75 g of gum arabic in 60 mL of water and stirring.
[0546] Next, the fundus of C57BL / 6J mice (8 weeks old, N=13) was irradiated with laser light at four locations in each eye under a slit lamp using a multicolor laser photocoagulation device. Immediately after irradiation, the medium or zaltoprofen solution (25 mg / kg) was orally administered once a day for 3 weeks, and the following evaluations were performed. It should be noted that (1) and (3) were performed on the same individual.
[0547] (1) CNV evaluation (N=3)
[0548] (2) EMT evaluation: type 1 collagen (N = 10)
[0549] (3) EMT evaluation: Vimentin (N=3)
[0550] Test Example 3-1: Inhibitory effect of zaltoprofen on choroidal neovascularization (CNV) induced by laser irradiation
[0551] Two weeks after laser irradiation, 500 mg of fluorescein sodium (Fluorescite) (1 mL / kg) was administered via the tail vein, and fluorescent fundus photographs were taken about 1 minute after administration. Based on the fluorescent fundus photographs taken, scores were given for the four sites of each eye based on the following evaluation criteria. The results are shown in Fig.21 , the representative image is shown in Fig. 22 .
[0552] [Evaluation criteria]
[0553] ·No fluorescence······0
[0554] ·Slightly fluorescent······1
[0555] Moderate fluorescence observed······2
[0556] ·See strong tendency······3
[0557] like Fig.21 As shown, regarding the CNV score caused by laser irradiation, the result of the zaltoprofen-administered group was significantly lower than that of the vehicle-administered group.
[0558] exist Fig. 22 In the figure, the arrow indicates the part that leaks fluorescence due to CNV. Fig. 22 As shown, CNV caused by laser irradiation was significantly suppressed in the zaltoprofen-administered group (right photograph) compared with the vehicle-administered group (left photograph).
[0559] Test Example 3-2: Zaltoprofen's inhibitory effect on EMT (EMT evaluation: type 1 collagen) induced by laser irradiation
[0560] Three weeks after laser irradiation, the animals were euthanized by cervical dislocation and the eyeballs were removed and fixed by immersion in 4% polyoxymethylene-phosphate buffer (Wako Pure Chemical Industries, Ltd.). The cornea, lens, and retina were removed from the eyeball to form an eye cup, and then washed three times with PBST. Next, dehydration was performed using 50% methanol and then 100% methanol solution, and incubation was performed with a blocking solution (1% BSA, 0.5% TritonX-100 / PBS) for 60 minutes. Furthermore, after standing overnight in the primary antibody (anti-collagen antibody, Rockland), it was reacted in the secondary antibody (Alexa488 antibody, Life technologies) for 1 hour and placed on a slide to prepare a flat stained specimen. The specimen was quantitatively evaluated after taking a photograph of the staining image obtained using an anti-type 1 collagen antibody using a microscope. The results are shown in Fig.23 .
[0561] like Fig.23 As shown in the figure, the amount of type 1 collagen produced by laser irradiation was significantly reduced in the zaltoprofen-administered group compared with the vehicle-administered group (p<0.05). That is, it was found that zaltoprofen exhibited a significant inhibitory effect on EMT.
[0562] Test Example 3-3: Inhibitory effect of zaltoprofen on EMT induced by laser irradiation (EMT evaluation: vimentin)
[0563] Three weeks after laser irradiation, the animals were euthanized by cervical dislocation and the eyeballs were removed and fixed by immersion in 4% paraformaldehyde-phosphate buffer (manufactured by Wako Pure Chemical Industries, Ltd.). The fixed eyeballs were immersed in 10% sucrose (manufactured by Wako Pure Chemical Industries, Ltd.) and 25% sucrose for 3 hours each, and eye cups were made. Frozen sections were made and attached to slides. The sections were observed under a microscope, and the sections in which the laser irradiation site could be confirmed were selected. Next, the slide with the sections attached was placed in HistoVT One (manufactured by Nacalai Tesque Co., Ltd.) diluted 10 times with water, and immersed at 70°C for 15 minutes. TrueBlack (manufactured by Biotium Co., Ltd.) diluted 20 times with 70% ethanol (manufactured by Wako Pure Chemical Industries, Ltd.) was added to the sections, and after standing at room temperature for several minutes, 5% goat serum (manufactured by Dako Japan Co., Ltd.) was added to the sections, and they were left standing at room temperature for 30 minutes for blocking. Next, Can Get Immunostain Solution B (manufactured by Toyobo Co., Ltd.) was added to the sections and left to stand overnight. Can Get was added to the secondary antibody (Alexa Fluor 546, manufactured by Thermo Fisher Scientific) and Hoechst 33342 (manufactured by Dojin Chemical Laboratories, Ltd.). Immunohistochemical staining solution B was added to the sections and allowed to stand for 30 minutes. The sections were observed and photographed using a fluorescence microscope under the following conditions.
[0564] Vimentin: excitation wavelength 520-550nm, detection wavelength 580nm
[0565] ·Nuclear: excitation wavelength 330-385nm, detection wavelength 420nm
[0566] The shooting results are shown in Fig.24 and Fig.25 . Fig.24 indicates the vehicle-administered group. Fig.24 The left photo shows a bright field image, and the right photo shows an overlapping image of vimentin (red) and nuclei (blue). Fig.25 In the figure, the left photo shows vimentin in the vehicle-administered group, and the right photo shows vimentin in the zaltoprofen-administered group. Fig.24 and Fig.25 In the figure, the circle indicates the vimentin-positive area caused by laser irradiation.
[0567] like Fig.24 As shown in the figure, a less pigmented part appeared near the RPE at the laser irradiation site (left photo), and staining of vimentin, a mesenchymal marker, was confirmed (right photo). It is believed that laser irradiation causes RPE to express vimentin and induce epithelial-mesenchymal transition (EMT). In addition, Fig.25 As shown, the RPE of the vehicle-administered group was vimentin-positive (left photo). On the other hand, in the zaltoprofen-administered group, the vimentin-positive area was reduced compared to the vehicle-administered group (right photo).
[0568] It is thus clear that zaltoprofen inhibits EMT in the laser irradiation model. That is, it is believed that zaltoprofen inhibits drusen formation by inhibiting EMT of RPE. In addition, even other compounds different from zaltoprofen, as long as they can significantly inhibit EMT, are speculated to be able to prevent and / or treat CNV.
[0569] [4. Demonstration of EMT in human specimens]
[0570] Test Example 4-1: Observation of the morphology of drusen in patients with AMD
[0571] Healthy control samples and retinal pigment epithelial cell (RPE cell) samples of AMD patients were obtained from the National Disease Research Interchange. These tissue samples were dewaxed by treating with xylene for 5 minutes × 3 times, 100% ethanol for 1 minute × 2 times, 90% ethanol for 1 minute, 80% ethanol for 1 minute, 70% ethanol for 1 minute, and water for 5 minutes. Stained with Mei's hematoxylin solution for 4 minutes and eosin solution for 1 minute. Treated in running water for 5 minutes, then treated with 70% ethanol for 1 minute, 80% ethanol for 1 minute, 90% ethanol for 1 minute, 100% ethanol for 1 minute × 2 times, and xylene for 5 minutes × 3 times, and sealed with dronabinol. Dry it at room temperature for more than 15 minutes, and then observe the RPE cells of healthy people and the RPE cells of AMD patients. The staining results obtained by hematoxylin-eosin staining are shown in Fig.26 .
[0572] Through careful research Fig.26 Observation results, the inventors of the present invention etc. found: in the macula of healthy people's control, the morphology of RPE cells is cubic, neatly arranged as a single layer by intercellular adhesion; in the macula of AMD patients where drusen exists, the morphological changes of RPE cells are spindle-shaped, and RPE cells obtain motor ability, and cells are stratified. According to these observation results, the inventors of the present invention etc. speculate that in the macula of AMD patients, the intercellular adhesion of RPE cells weakens and produces morphological changes, thus establishing the following hypothesis: RPE cells have produced the phenomenon of losing epitheliality, i.e. EMT (Epithelial-mesencyamal transition, epithelial-mesenchymal transition). In the following Test Example 4-2 to Test Example 4-4, based on the hypothesis, a test for producing EMT in RPE cells was carried out.
[0573] Test Example 4-2: Disappearance of epithelial markers in drusen of AMD patients
[0574] The disappearance of epithelial markers in healthy control samples and retinal pigment epithelial cell (RPE cell) samples of AMD patients was verified by immunohistochemistry (IHC). After the tissue samples were incubated at 56°C for 30 minutes in a gas phase incubator, they were treated with xylene for 5 minutes × 3 times, 100% ethanol for 1 minute × 2 times, 90% ethanol for 1 minute, 80% ethanol for 1 minute, 70% ethanol for 1 minute, and water for 5 minutes to dewax. After removing melanin from the tissue according to the manufacturer's protocol using the Delicate Melanin Bleach Kit for Special Stains and IHC (Polysciences #24909-1), the antigen was activated by microwave treatment for 10 minutes using a citrate buffer pH 6.0. After standing at room temperature for 30 minutes, the intrinsic peroxidase was inactivated by treatment with PBS for 5 minutes, 3% hydrogen peroxide / PBS solution for 5 minutes, and PBS for 5 minutes. The tissue was blocked by standing in a 3% BSA / PBS solution at room temperature for 30 minutes. As the primary antibody, 200 μl of anti-E-cadherin antibody (BD Biosience #610181) diluted 500 times with a 1.5% BSA / PBS solution and anti-cytokeratin 18 antibody (Cell signaling Technology #4548) diluted 1000 times were added to each tissue and reacted with the tissue at 4°C for 17 hours. The tissue reacted with the primary antibody was washed with PBS for 5 minutes × 3 times, and then reacted with the secondary antibody at room temperature for 30 minutes using the Mouse on Mouse (MOM) Elite Peroxidase Kit (Vector Laboratories #PK-2200), washed with PBS for 5 minutes × 3 times, and then ABC reaction was performed at room temperature for 30 minutes according to the manufacturer's protocol. After the tissue was washed with PBS for 5 minutes × 3 times, it was stained at room temperature for 3 minutes using ImmPACT DAB peroxidase (HRP) substrate (Vector Laboratories #SK-4105). After the stained tissue was stained with M-type neohematoxylin (Muto Chemical Co., Ltd. #30141), it was allowed to stand in running water for 3 minutes, treated with 70% ethanol for 1 minute, 80% ethanol for 1 minute, 90% ethanol for 1 minute, 100% ethanol for 1 minute × 2 times, and xylene for 5 minutes × 3 times, and sealed with dronabinol. It was dried at room temperature for more than 15 minutes, and then the RPE cells of healthy people and AMD patients were observed. The results are shown in Fig. 27 .
[0575] like Fig. 27 As shown, for healthy controls (Control), staining of E-cadherin (E-Cadherin) as an epithelial marker was confirmed at the intercellular adhesion site, but in the peripheral part of AMD patient's drusen, staining of E-cadherin was not confirmed between cells (left side staining photo). In addition, for healthy controls, strong staining of cytokeratin 18 (Cytokeratin18) as an epithelial marker was confirmed in the whole RPE cells, but in the peripheral part of AMD patient's drusen, signal reduction (right side staining photo) was compared with it.
[0576] This confirmed that RPE cells in AMD patients had lost and decreased epithelial properties.
[0577] Experimental Example 4-3: Hyperexpression of Mesenchymal Markers in Drusen of AMD Patients
[0578] The hyperactivity of mesenchymal markers in healthy human control samples and retinal pigment epithelial cell (RPE cell) samples of AMD patients was verified by immunohistochemistry (IHC). After the tissue samples were incubated at 56°C in a gas phase incubator for 30 minutes, they were dewaxed by treating with xylene for 5 minutes × 3 times, 100% ethanol for 1 minute × 2 times, 90% ethanol for 1 minute, 80% ethanol for 1 minute, 70% ethanol for 1 minute, and water for 5 minutes. Antigens were activated by microwave treatment for 10 minutes using a citric acid buffer pH 6.0. After standing at room temperature for 30 minutes, the intrinsic peroxidase was inactivated by treating with PBS for 5 minutes, 3% hydrogen peroxide / PBS solution for 5 minutes, and PBS for 5 minutes. The tissue was blocked by standing at room temperature for 30 minutes in a 3% BSA / PBS solution. As the primary antibody, 200 μl of anti-fibronectin antibody (abcam #45688) diluted to 100 times with 1.5% BSA / PBS solution and anti-vimentin antibody (Sigma-Aldrich #6630) diluted to 10,000 times were added to each tissue and reacted with the tissue at 4°C for 17 hours. The tissue reacted with the primary antibody was washed with PBS for 5 minutes × 3 times, and then reacted with the secondary antibody at room temperature for 30 minutes using VECTASTAIN Elite ABC Rabbit IgG Kit (Vector Laboratories #PK-6101) for anti-fibronectin antibody and Mouse on Mouse (MOM) Elite Peroxidase Kit (Vector Laboratories #PK-2200) for anti-vimentin antibody. After washing with PBS for 5 minutes × 3 times, ABC reaction was performed at room temperature for 30 minutes according to the manufacturer's protocol. After the tissue was washed with PBS for 5 minutes × 3 times, ImmPACT AMEC red peroxidase (HRP) substrate (Vector Laboratories company #SK-4285) was used to develop the color at room temperature for 3 minutes and washed with distilled water for 5 minutes. After the developed tissue was stained with M-type new hematoxylin (Muto Chemical Co., Ltd. #30141), it was left to stand in running water for 3 minutes and sealed with VectaMount AQ water-soluble mounting medium (Vector Laboratories company #H-5501). It was dried at room temperature for more than 15 minutes, and then the RPE cells of healthy people and AMD patients were observed. The results are shown in Fig.28 .
[0579] like Fig.28Shown in, in the normal RPE cell of healthy person control (Control), do not see the dyeing of fibronectin (Fibronectin) as interstitial system mark.On the other hand, in drusen and RPE cell of AMD patient, fibronectin demonstrates positive.In addition, in the RPE cell of healthy person control, do not see the dyeing of vimentin (vimentin) as interstitial system mark.The RPE cell of AMD patient drusen demonstrates vimentin positive.
[0580] The above analysis results clearly show that the RPE cells of AMD patients lose or weaken the epithelial characteristics of health, and acquire mesenchymal characteristics and hypertrophy in AMD. In other words, it is clear that in AMD, RPE cells undergo a transformation from epithelial characteristics to mesenchymal characteristics, epithelial-mesenchymal transition (EMT).
[0581] Test Example 4-4: Verification using cynomolgus monkey model
[0582] Sections were prepared from healthy cynomolgus macaque control samples and retinal pigment epithelial cell (RPE cell) samples of AMD cynomolgus macaque models, and the disappearance of epithelial markers and the hyperplasia of mesenchymal markers were verified by immunohistochemistry (IHC). Tissue samples were dewaxed by treating with xylene for 5 minutes × 3 times, 100% ethanol for 1 minute × 2 times, 90% ethanol for 1 minute, 80% ethanol for 1 minute, 70% ethanol for 1 minute, and distilled water for 10 minutes. Antigens were activated by microwave treatment for 10 minutes using a citric acid buffer pH 6.0. After standing at room temperature for 30 minutes, the endogenous peroxidase was inactivated by treating with PBS for 5 minutes, 3% hydrogen peroxide / PBS solution for 5 minutes, and PBS for 5 minutes. The tissue was blocked by standing at room temperature for 20 minutes in a 3% BSA / PBS solution. As the primary antibody, 200 μl of anti-E-cadherin antibody (BD Biosience #610181) diluted 500-fold with 1.5% BSA / PBS solution, anti-cytokeratin 18 antibody (abcam #ab668) diluted 2000-fold, and anti-fibronectin antibody (Epitomics #1574-1) diluted 600-fold were added to each tissue and allowed to react with the tissue at 4°C for 17 hours. The tissue reacted with the primary antibody was washed with PBS for 5 minutes × 3 times, and then reacted with the secondary antibody at room temperature for 30 minutes using VECTASTAIN Elite ABC Mouse IgG Kit (Vector Laboratories #PK-6102) for anti-E-cadherin antibody and anti-cytokeratin 18 antibody, and VECTASTAIN EliteABC Rabbit IgG Kit (Vector Laboratories #PK-6101) for anti-fibronectin antibody, and then washed with PBS for 5 minutes × 3 times, and then ABC reaction was performed at room temperature for 30 minutes according to the attached protocol. The tissue was washed with PBS for 5 minutes × 3 times, and then color was developed at room temperature for 3 minutes using ImmPACT DAB Peroxidase (HRP) Substrate (Vector Laboratories #SK-4105) for anti-E-cadherin antibody, and TMB Peroxidase Substrate Kit (Vector Laboratories #SK-4400) for anti-cytokeratin 18 antibody and anti-fibronectin antibody, and then washed with distilled water for 5 minutes.About the tissue through color development, use M type new hematoxylin (Muto Chemical Co., Ltd. #30141) for anti-E-cadherin antibody, use VECTOR nuclear fast red (Vector Laboratories company #H-3403) for anti-cytokeratin 18 antibody and anti-fibronectin antibody to dye.Stand in running water for 10 minutes, utilize 70% ethanol treatment for 1 minute, utilize 80% ethanol treatment for 1 minute, utilize 90% ethanol treatment for 1 minute, utilize 100% ethanol treatment for 1 minute × 2 times, utilize xylene treatment for 5 minutes × 3 times, use dronabinol to be sealed.Make it dry at room temperature for more than 15 minutes, then observe the RPE cell of the RPE cell of the RPE cell of the RPE cell model of AMD of cynomolgus macaque control.Result is shown in. Fig.29 .
[0583] The macula is present only in higher primates, and macular degeneration is also present only in certain primates. To verify the pathology of macular degeneration, the pathology of cynomolgus monkeys, which are known as a model animal for macular degeneration, was analyzed.
[0584] like Fig.29 Shown, about the morphology of RPE cell, in healthy cynomolgus monkey control (Control), confirm that RPE cell is cubic, is neatly arranged as single layer by cell-cell adhesion.On the other hand, in the RPE cell of cynomolgus monkey of AMD, morphological change is spindle-shaped, confirms the stratification of cell at the edge of drusen.
[0585] In addition, about epithelial markers, in the macula of healthy cynomolgus monkey control (Control), the staining of E-cadherin was confirmed at the intercellular adhesion site of RPE cells, but in the RPE cells of cynomolgus monkeys with AMD where drusen existed, the staining of E-cadherin was not confirmed between cells. In addition, in healthy cynomolgus monkey control, the staining of stronger cytokeratin 18 was confirmed in the whole RPE cells, but in the drusen of cynomolgus monkeys with AMD, compared with the control, the signal decreased.
[0586] In addition, regarding the mesenchymal marker, fibronectin was stained in drusen of cynomolgus monkeys with AMD, and accumulation in RPE cells and drusen was confirmed.
[0587] According to the result of the aforementioned test example, EMT was produced in the RPE cells of drusen. Therefore, the inventors of the present invention etc. speculate that if the EMT of RPE cells can be suppressed, the formation of drusen can be suppressed. In the following test example 5-1, in order to retrieve the compound that suppresses the EMT of RPE cells, or in order to evaluate the influence of candidate agents on EMT in RPE cells, the cell model that can induce EMT to RPE cells in vitro was studied.
[0588] [5. Construction of EMT cell model]
[0589] Experimental Example 5-1: Study on the induction conditions of EMT in RPE cells
[0590] The inventors conducted an experiment to stimulate RPE cells (retinal pigment epithelial cell line: ARPE-19, the same below) under 10 conditions using cytokines or growth factors (TNF-α / IL-1β / TGF-β), and found that significant EMT induction was induced. It is believed that the cell model induced by EMT using cytokines or growth factors reflects the EMT induction mechanism inferred in AMD patients.
[0591] The 10 conditions are as follows.
[0592] (1) TNF-α 100 ng / mL
[0593] (2) IL-1β 100 ng / mL
[0594] (3) IL-1β 20 ng / mL
[0595] (4)TNF-α500ng / mL+TGF-β5ng / mL
[0596] (5)TNF-α200ng / mL+TGF-β5ng / mL
[0597] (6)TNF-α100ng / mL+TGF-β5ng / mL
[0598] (7)TNF-α100ng / mL +TGF-β10ng / mL
[0599] (8)TNF-α100ng / mL +TGF-β25ng / mL
[0600] (9)IL-1β100ng / mL+TGF-β5ng / mL
[0601] (10)IL-1β20ng / mL+TGF-β5ng / mL
[0602] Test Example 5-2: Verification of EMT based on expression changes of EMT marker molecules RNA was extracted from stimulated RPE cells, and expression changes were verified.
[0603] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 5-1, and after 48 hours of EMT induction, cells were recovered. The recovered cells were washed with PBS, 350 μL of RLT buffer (QIAGEN company) was added, and RNA collection was lysate was made. Using RNeasy micro kit (QIAGEN company #74004), total RNA was extracted from the lysate, and SuperScript III First-Strand Synthesis SuperMix (Invitrogen company #11752-250) for qRT-PCR was used to make cDNA from the RNA 2 μg obtained. Using the obtained cDNA 50ng as a template, real-time PCR (ABIPrism 7500 sequence detection system) was performed according to the manufacturer's draft, and the expression of mRNA of each gene was quantitatively analyzed. Specific primers for each gene were purchased from Invitrogen company. The Ct (Threshold Cycle) value of each gene was normalized by the internal control, and the ratio relative to the untreated sample was calculated.
[0604] The results are shown in Figure 1 .
[0605] like Figure 1 As shown in A and B in Figure 3, the expression of E-cadherin, a marker of epithelial lineage, was decreased in stimulated RPE cells ( Figure 1 A), the expression of N-cadherin, a mesenchymal marker, was upregulated ( Figure 1 B in the figure). This cadherin conversion is a representative phenomenon of EMT. In addition, the mesenchymal marker represented by fibronectin ( Figure 1 C) and the hyperregulation of EMT-related transcription factors (Snail, Slug, ZEB1) ( Figure 1 E to G in Figure 1) and the expression of ECM represented by type I collagen (COL1A1) ( Figure 1 D) in the figure, it was confirmed that RPE cells induced EMT due to stimulation.
[0606] Test Example 5-3: Verification of changes in EMT marker expression over time using microarray
[0607] The formation of drusen-like structures at the time of EMT induction and the EMT induction status at that time were analyzed.
[0608] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 5-1, and cells were recovered after 1 hour, 4 hours, 12 hours, 24 hours, 48 hours, and 72 hours of EMT induction. The recovered cells were washed with PBS, 350 μL of RLT buffer was added, and RNA was collected and lysate was made. Using RNeasy micro kit (QIAGEN company #74004), total RNA was extracted from the lysate, and fluorescent labeling was performed using Low InputQuickAmp calibration kit (Agilent Technologies company #5190-2305). Labeled cRNA is hybridized in the human whole genome oligo DNA microarray kit (Agilent Technologies company #G4112F) according to the protocol specified by the manufacturer. The hybridized slides were cleaned using the Gene Expression Cleaning Kit (Agilent Technologies #5188-5327) and scanned using the Agilent Microarray Scanner (Agilent Technologies #G2505B). The scanned images were digitized using Feature Extraction software version 9.5.1 (Agilent Technologies). The numerical data were normalized using the Grobal normalization method. The results are shown in Figure 2 .
[0609] like Figure 2 As shown, the peak of decrease or increase of EMT markers varies depending on the gene, and occurs 12 hours or 72 hours after EMT induction. The decreased epithelial markers and increased mesenchymal markers and ECM are as follows.
[0610] As epithelial markers decreased by EMT induction, ID1, ID2, MUC1, cytokeratin 18 (KRT18), THBS1, VIL2, E-cadherin (CDH1), and TGFB2 were confirmed.
[0611] As mesenchymal markers and ECMs that are hyperactive due to EMT induction, FGF2, TWIST1, VIM, CD44, ZEB1, RDX, MMP9, FN1, TGFB1, RHOA, ZEB2, MMP2, TJP1, CTNNB1, MMP3, ETS1, SNAI1, SNAI2, HAS2, FGF1, SERPINE1, CDH2, MSN, TCF3, SDC1, ITGAV, COL1A1, and SPARC were confirmed.
[0612] 24 hours after EMT induction, drusen-like structures were formed on the culture plate seeded with RPE cells. The expression of epithelial markers represented by E-cadherin and cytokeratin 18 decreased, while the expression of mesenchymal markers and ECM groups represented by fibronectin / vimentin increased, and a clear correlation was observed between the formation of drusen-like structures and the EMT induction state.
[0613] Therefore, it was confirmed that the formation of drusen-like structures occurred through EMT of RPE cells.
[0614] Test Example 5-4: Verification of EMT induction based on hyperkinetic activity
[0615] The enhanced motility of RPE cells caused by EMT was evaluated using an invasion assay (cell invasion analysis), which is a method for evaluating the motility and invasiveness of cells.
[0616] RPE cells (ARPE-19) were seeded on a culture plate and incubated at 37°C for 5 days. For RPE cells, EMT was induced under the conditions described in Experimental Example 5-1, and the cells were recovered 24 hours after EMT induction. The recovered cells were inoculated into BD Biocoat Matrigel invasion chambers (BD Biosciece #354480) and further incubated at 37°C for 24 hours. After incubation, non-infiltrating cells were removed according to the manufacturer's protocol, and 100% methanol was added to fix the cells at room temperature for 15 minutes. Giemsa staining solution (Nacalai Tesque #37114-35) was added, and after staining at room temperature for 30 minutes, the cells were washed with PBS for 5 minutes × 2 times. After washing, the membrane remaining from the infiltrated cells was recovered and sealed on a glass slide. Allow it to dry for more than 15 minutes, then observe and take images using a microscope, and count the number of cells in the image. The results are shown in Fig.30 .
[0617] like Fig.30 A and Fig.30 Shown in B, the infiltrating cell number of RPE cell increases due to stimulation, confirms that the motor ability of RPE cell is hyperactive. RPE cells as epithelial cells do not usually have motor ability. In this way, the situation that the epithelial cells that originally did not have motor ability obtain motor ability is also a representative phenomenon of EMT.
[0618] Experimental Example 5-5: Morphological observation of RPE cells undergoing EMT
[0619] RPE cells (ARPE-19) were seeded on a culture plate and incubated at 37°C for 5 days. For RPE cells, EMT was induced under the conditions described in Experimental Example 5-1, and the cells were observed 48 hours after EMT induction. In addition, in order to observe the overall image of the culture plate under a low-power field of view, the observed cells were treated with a 4% polyformaldehyde solution at room temperature for 30 minutes and fixed, and then washed 3 times with PBS. Treated with 100% methanol at room temperature for 10 minutes × 2 times, Giemsa staining solution (NacalaiTesque #37114-35) was added, and stained at room temperature for 15 minutes. After washing with methanol 3 times, it was dried at room temperature for 3 hours. The dried cells were observed under a microscope. The results are shown in Fig.31 .
[0620] When EMT was induced in RPE cells under the conditions described in Experimental Example 5-1, Fig. 22 As shown by the arrow in B, aggregates were formed and drusen-like structures were confirmed. On the other hand, when EMT was not induced, Fig.31 As shown in A, PRE cells do not form aggregates but maintain a fusion state. Fig.31 C and Fig.31 D in the figure is to observe whether EMT is induced under low power field. Fig.31 As shown in D in FIG. 1 , it was confirmed that the drusen-like structures (Focus) were morphologically similar to the drusen ( Fig.31 E in). Thus prove, in RPE cells, due to the mesenchymal hypertrophy caused by EMT induction, drusen-like structures are formed. In addition, the drusen-like structures in the RPE cells can be effectively used as a model for reproducing AMD patient's drusen in vitro.
[0621] [6. Evaluation and / or screening of EMT inhibitory compounds]
[0622] Experimental Example 6-1: Expression changes of EMT markers 1
[0623] As previously mentioned, confirm that by stimulating RPE cells, the change of EMT markers or the hyperactivity of motor ability can be caused, and drusen-like structures are formed, thereby constructing a cell model that can induce EMT. Using this cell model, select the compound that inhibits EMT. In addition, by using this cell model, EMT inhibitory compounds can be evaluated.
[0624] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 5-1, and the evaluation compound (also referred to as the tested agent) was added. As an EMT induction control, a sample without the addition of the evaluation compound (tested agent) was used. After EMT induction for 48 hours, the cells were fixed at room temperature for 30 minutes using a 4% polyformaldehyde solution and then washed 3 times with PBS. Treated with 0.2% Triton-X / PBS solution for 5 minutes and washed 3 times with PBS. After staining the cells with a fluorescent staining solution (0.2% Phalloidin-Alexa 568 (Molecular Probes Company #A12380) / 0.05% Hochest33342 (Invitrogen Company #H3570) / 3% BSA-PBS) at room temperature for 1 hour, the cells were washed 5 minutes × 3 times with PBS. Cells that have been fluorescently stained were imaged using ImageExpress Micro (Molecular Devices) and digitized using MetaXpress2.0 (Molecular Devices). The degree of cluster formation (cluster level) was analyzed by numerical data, and the numerical value when no compound was added was used as a benchmark, and the cluster formation inhibition rate was calculated according to the following formula 1 to verify the EMT inhibitory effect of each compound. The degree of cluster formation (cluster level) is obtained by taking the number and volume of clusters as indicators.
[0625] (Formula 1)
[0626]
[0627] The IC50 in the table was calculated using the following formula 2.
[0628] (Formula 2)
[0629] IC50=10^(LOG(A / B)*(0.5-C) / (DC)+LOG(B))
[0630] A: With a high concentration of 50%
[0631] B: sandwiched with 50% low concentration
[0632] C: Inhibition rate at a low concentration of 50%
[0633] D: Inhibition rate at high concentrations of 50%
[0634] As a result, the following compounds were found to have an EMT inhibitory effect.
[0635] Table 1
[0636] Among the EMT-inhibiting compounds listed in Table 1 above, the EMT-inhibiting effects of five representative compounds (oxaprozin, epalrestat, zafirlukast, amlexanox, and zaltoprofen) were evaluated using the above-mentioned cell model.
[0637] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 5-1, and 5 representative compounds (oxaprozin, epalrestat, zafirlukast, amlexanox, zaltoprofen) were added at the same time. After 48 hours of EMT induction, the cells were recovered. As a control, a sample without the addition of the evaluation compound (tested agent) was used. The recovered cells were washed with PBS, 350 μL of RLT buffer was added, and RNA was collected and lysate was made. Using RNeasy micro kit (QIAGEN company #74004), total RNA was extracted from the lysate, and cDNA was made from the obtained RNA 2 μg using SuperScript III First-Strand Synthesis SuperMix (Invitrogen company #11752-250) for qRT-PCR. The obtained cDNA 50ng was used as a template, and real-time PCR (ABIPrism 7500 sequence detection system) was performed according to the manufacturer's protocol to quantitatively analyze the expression of mRNA of each gene. Specific primers for each gene were purchased from Invitrogen. The Ct (Threshold Cycle) value of each gene was normalized by the intrinsic control and the ratio relative to the non-treated sample was calculated. The results are shown in Figures 3 to 7 .
[0638] exist Figures 3 to 7 In each graph, the bar graph on the left represents the expression level of each gene when EMT is not induced. The bar graph in the middle represents the expression level of each gene when EMT is induced. The bar graph on the right represents the expression level of each gene when an EMT inhibitory compound is given. In addition, Figures 3 to 7 The results of using oxaprozin, epalrestat, zafirlukast, amlexanox, and zaltoprofen as EMT inhibitory compounds are shown.

[0657] like Figures 3 to 7 As shown in the figure, among the EMT markers, the expressions of Snail, Slug, CDH3, MMP1, MMP7, which are mesenchymal markers, and COL5A3, COL6A3, LAMC2, HMMR, and TNC, which are ECM markers, were all suppressed when any EMT inhibitory compound was applied. Thus, it was confirmed that these 10 EMT markers were commonly suppressed by EMT inhibitory compounds. Even EMT markers other than these 10 were also suppressed. Figure 3 As shown in Figure 2, the expression of ZEB2, MMP3, COL1A1, COL1A2, CSPG4, and SRGN was confirmed to be decreased in response to oxaprozin. Figure 4 As shown in Figure 2, it was confirmed that the expression of ZEB2, CDH2, FN1, VIM, COL1A1, COL1A2, COL5A2, COL13A1, CSPG4, and SRGN was decreased in epalrestat. Figure 5 As shown in Figure 2, zafirlukast confirmed that the expression of MMP3, COL13A1, LAMB3, and CSPG4 decreased. Figure 6 As shown in Figure 2, it was confirmed that the expression of ZEB2, CDH2, MMP3, COL1A1, and COL13A1 was decreased in Amlexanox. Figure 7 As shown, in the case of zaltoprofen, the expression of ZEB2, FN1, COL13A1, and CSPG4 was confirmed to be decreased. It was confirmed that these EMT markers can also be indicators of inhibition by EMT inhibitory compounds.
[0658] Experimental Example 6-2: Expression changes of EMT markers 2
[0659] IC50 was determined for 5 compounds (aluminum flufenamate, mefenamic acid, sulindac, teipfic acid, and seratrolast) by the same method as in Test Example 6-1. The results are shown in Table 2.
[0660] [Table 2]
[0661]
[0662] As shown in Table 2, for the five compounds (flufenamic acid aluminum (added concentration: 28 μM (Cmax)), mefenamic acid (added concentration: 39 μM (Cmax)), sulindac (added concentration: 100 μM), teprofenic acid (added concentration: 1000 μM), seroquel (added concentration: 31 μM (Cmax))) that confirmed the EMT inhibitory effect, the expression changes of EMT markers were evaluated by the same method as in Test Example 6-1. The results are shown in Figures 8 to 12 .
[0663] like Figures 8 to 12 As shown, it was confirmed that the five EMT inhibitory compounds (flufenamic acid aluminum, mefenamic acid, sulindac, teipfic acid, and seratrolast) also reduced the expression of EMT markers during EMT induction.
[0664] Test Example 6-3: Hyperkinesia Inhibition Test
[0665] Using the invasion assay described in Test Example 5-4 above, the effect of an EMT-inhibiting compound on RPE cells whose motility is enhanced due to EMT was confirmed.
[0666] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 5-1, and 5 compounds (oxaprozin, epalrestat, zafirlukast, amlexanox, zaltoprofen) were added. After 24 hours of EMT induction, the cells were recovered. The recovered cells were inoculated into the BD Biocoat Matrigel invasion chamber (BD Biosciece company #354480) and further incubated at 37 ° C for 24 hours. After incubation, after removing non-infiltrating cells according to the manufacturer's protocol, 100% methanol was added and the cells were fixed at room temperature for 15 minutes. Giemsa staining solution (Nacalai Tesque company #37114-35) was added, and after staining at room temperature for 30 minutes, PBS was used to wash for 5 minutes × 2 times. After washing, the membrane remaining in the infiltrated cells was recovered and sealed on a slide. After drying for more than 15 minutes, the cells were observed and photographed using a microscope, and the number of infiltrating cells was counted. Figure 32 to Figure 34 .
[0667] Figure 32 to Figure 34 are the results of using epalrestat, amlexanox, and zafirlukast as EMT inhibitory compounds. Figure 32 to Figure 34 In the bar graphs, the white bar graph on the left represents the number of infiltrating RPE cells when EMT is induced, and the black bar graphs on the right represent the number of infiltrating RPE cells when EMT inhibitory compounds are added from low concentration to high concentration, from the left.
[0668] like Figure 32 to Figure 34 As shown in the figures, it was confirmed that the motility induced by EMT in RPE cells was significantly inhibited in a concentration-dependent manner by the EMT inhibitory compound.
[0669] [7. Evaluation of drug efficacy by drusen-like structure inhibition test]
[0670] RPE cells (ARPE-19) were inoculated on a culture plate and incubated at 37 ° C for 5 days. For RPE cells, EMT was induced under the conditions described in Test Example 5-1, and 5 compounds (oxaprozin, epalrestat, zafirlukast, amlexanox, zaltoprofen) were added at the same time, and the cells were observed 48 hours after EMT induction. As an EMT induction control, a sample without the addition of the evaluation compound (tested drug) was used. The observed cells were treated with 4% polyformaldehyde solution at room temperature for 30 minutes and fixed, and then washed 3 times with PBS. Treated with 0.2% Triton-X / PBS solution for 5 minutes and washed 3 times with PBS. The cells were stained with a fluorescent staining solution (0.2% Phalloidin-Alexa568 (Molecular Probes #A12380) / 0.05% Hochest 33342 (Invitrogen #H3570) / 3% BSA-PBS) at room temperature for 1 hour and then washed with PBS for 5 minutes × 3 times. The fluorescently stained cells were imaged using Image Express Micro (Molecular Devices) and quantified using MetaXpress2.0 (Molecular Devices). The degree of cluster formation was analyzed by numerical data, and the inhibition rate of cluster formation was calculated based on the absence of compound addition and the absence of EMT induction as the benchmark to verify the EMT inhibitory effect of each compound. For the cells after obtaining the fluorescent image, in order to observe the entire image at a low magnification field of view, they were treated with 100% methanol at room temperature for 10 minutes × 2 times, and Giemsa staining solution (Nacalai Tesque #37114-35) was added, and stained at room temperature for 15 minutes. After washing with methanol three times, the cells were dried at room temperature for 3 hours. The dried cells were observed under a microscope. The results are shown in Figure 35 to Figure 39 The agglomerate formation inhibition rate was calculated according to the formula 1 shown in the above-mentioned Test Example 6-1.
[0671] Figure 35 to Figure 39 The results are as follows: oxaprozin, epalrestat, amlexanox, zafirlukast, and zaltoprofen were used as EMT inhibitory compounds. Figure 35 to Figure 39 As shown, it was confirmed that the EMT inhibitory compounds all inhibited the drusen-like structures formed in the RPE cell model in a concentration-dependent manner. That is, the IC50 values in the drusen-like structure inhibition test were 61.0 μM for oxaprozin, 16.9 μM for epalrestat, 32.5 μM for amlexanox, 3.8 μM for zafirlukast, and 16.5 μM for zaltoprofen.
[0672] Based on the new knowledge that drusen is a structure caused by EMT of RPE cells, it was shown that drusen can be inhibited by applying EMT-inhibiting compounds to drusen. From this result, it is speculated that even known EMT-inhibiting compounds have the same effect on drusen.
[0673] For the five EMT-inhibiting compounds, the peak plasma concentration (Cmax) of the drug was determined from the interview form and accompanying documents of each drug by the following method.
[0674] The results are shown in Table 3.
[0675] [Table 3]
[0676]
[0677] As shown in Table 3, the blood concentrations of the five EMT-inhibiting compounds were sufficient to exert the expected effects on AMD.
[0678] [Test Example 8: In vivo model test for evaluating drusen inhibition]
[0679] Test Example 8-1: Inducing the formation of drusen-like structures in the posterior part of the eye (retinal area)
[0680] (1) Method for inducing drusen-like structures by inducing inflammation in the posterior ocular region (retinal region)
[0681] 400 ng of recombinant mouse TNF-a (R&D Systems #410-MT) was administered to the retinal periphery of the posterior eye of the mouse.
[0682] The method of administration is as follows.
[0683] 1) Prepare 2.5 μL of TNF-a (160 ng / μL) dissolved in PBS.
[0684] 2) Open the eyelids in such a way that the mouse's eyeball can be clearly observed.
[0685] 3) Insert the needle until you feel slight resistance and inject the drug solution (400 ng / eye).
[0686] (2) Method for preparing eyeball tissue samples
[0687] Two weeks after administration, the eyeballs were removed and formalin-fixed paraffin-embedded blocks were prepared.

They were stained with Meier's hematoxylin solution for 4 minutes and eosin solution for 1 minute. They were treated in running water for 5 minutes, then treated with 70% ethanol for 1 minute, 80% ethanol for 1 minute, 90% ethanol for 1 minute, 100% ethanol for 1 minute × 2 times, and xylene for 5 minutes × 3 times, and sealed with dronabinol. They were dried at room temperature for more than 15 minutes, and then the untreated RPE cells and inflammation-induced RPE cells were observed. The results are shown in Fig.40 .
[0690] like Fig.40 Shown in, by inflammation induction and form drusen sample structure (part surrounded by dotted line) in retinal area.Confirm that the retinal pigment epithelial cell of no treatment group presents cubic form, contacts closely with adjacent cell, and demonstrates 1 layer of arrangement (photo above).On the other hand, confirm that the retinal pigment epithelial cell that is arranged as 1 layer after inflammation induction is not observed, and is present in the inside, surrounding of drusen sample structure body, disappears with the close connection of adjacent cell, and its form becomes spindle-shaped (photo below) from cubic shape.
[0691] (4) Evaluation method of each marker by immunohistochemistry
[0692] The eyeball tissue sections were made from the blocks. After the tissue samples were incubated at 56°C in a gas phase incubator for 30 minutes, they were treated with xylene for 5 minutes × 3 times, 100% ethanol for 1 minute × 2 times, 90% ethanol for 1 minute, 80% ethanol for 1 minute, 70% ethanol for 1 minute, and water for 5 minutes to dewax. After removing the melanin in the tissue according to the manufacturer's protocol using a refined melanin kit for special staining and IHC (Polysciences #24909-1), the antigen was activated by microwave treatment for 10 minutes using a citrate buffer pH 6.0. After standing at room temperature for 30 minutes, the intrinsic peroxidase was inactivated by treatment with PBS for 5 minutes, 3% hydrogen peroxide / PBS solution for 5 minutes, and PBS for 5 minutes. The tissue was blocked by standing at room temperature for 30 minutes in a 3% BSA / PBS solution. As the primary antibody, 200 μL of anti-E-cadherin antibody (BD Biosience #610182) diluted 500-fold with 1.5% BSA / PBS solution, anti-cytokeratin antibody (Sigma #C2931) diluted 1000-fold, anti-fibronectin antibody (abcam #45688) diluted 1000-fold, and anti-vimentin antibody (Cell signaling Technology #5741) diluted 100-fold were added to each tissue and reacted with the tissue at 4°C for 17 hours. The tissue reacted with the primary antibody was washed with PBS for 5 minutes × 3 times, and then reacted with the secondary antibody (Mouse on Mouse (MOM) Elite Peroxidase Kit (Vector Laboratories #PK-2200) for anti-E-cadherin antibody and anti-cytokeratin antibody, and VECTASTAIN Elite ABC Rabbit IgG Kit (Vector Laboratories #PK-6101) for anti-fibronectin antibody and anti-vimentin antibody) at room temperature for 30 minutes, washed with PBS for 5 minutes × 3 times, and then ABC reaction was performed at room temperature for 30 minutes according to the manufacturer's protocol. The tissue was washed with PBS for 5 minutes × 3 times, and then color was developed at room temperature for 3 minutes using ImmPACT AMEC Red Peroxidase (HRP) Substrate (Vector Laboratories #SK-4285). The stained tissue was stained with M-type neo-hematoxylin (Muto Chemical Co., Ltd. #30141), then allowed to stand in running water for 3 minutes, treated with 70% ethanol for 1 minute, 80% ethanol for 1 minute, 90% ethanol for 1 minute, and 100% ethanol for 1 minute × 2 times, treated with xylene for 5 minutes × 3 times, and sealed with dronabinol.The samples were dried at room temperature for 15 minutes or longer and then observed. The results for E-cadherin are shown in FIG. Fig.41 The results for cytokeratin are shown in Fig.42 The results for fibronectin are shown in Fig.43 The results for vimentin are shown in Fig.44 .
[0693] like Fig.41 As shown, in the untreated retinal epithelial cells, strong positive E-cadherin staining was observed between cells, and strong cell-cell adhesion was maintained (upper photo). On the other hand, in the retinal pigment epithelial cells inside and around the drusen-like structures formed by inflammation induction, staining disappeared (lower photo).
[0694] like Fig.42 As shown, in the untreated retinal epithelial cells, strong positive staining of cytokeratin was observed between cells (upper photograph). On the other hand, in the retinal pigment epithelial cells, especially around the drusen-like structures formed by inflammation induction, the staining disappeared (lower photograph).
[0695] like Fig.43 As shown, in the untreated retinal epithelial cells (the part surrounded by the dotted line), the signal was negative, and no expression of fibronectin was observed (upper photo).
