Description

[Technical Field]

[0001] Cross-reference of related applications This application claims the interests of U.S. Provisional Patent Application No. 63 / 162,483, filed on 17 March 2021, which is incorporated herein by reference in its entirety. [Background technology]

[0002] I. Background technology Plasma kallikrein (pKa) is a serine protease thymogen in the blood that is converted to its catalytically active form by coagulation factor XIIa and contributes to innate inflammatory responses and the endogenous blood coagulation cascade. Mechanisms that trigger activation of this pathway in vivo include interaction with polyphosphate released from activated platelets and deficiency of C1 inhibitor (C1-INH), the major physiological inhibitor of PKa. Cleavage of high molecular weight kininogen mediated by PKa generates bradykinin (BK), a potent vasodilatory and pro-inflammatory nonapeptide, which activates the bradykinin 2 receptor. Subsequent cleavage of BK by carboxypeptidase generates des-Arg9-BK, which activates the B1 receptor. Both B1 and B2 receptors are expressed in vascular, glial, and neuronal cell types, with the highest levels of retinal expression detected in the ganglion cell layer as well as the inner and outer granular layers. Activation of B1 and B2 receptors causes vasodilation and increases vascular permeability.

[0003] PKa is also associated with numerous disorders, including hereditary angioedema (HAE), an autosomal dominant disorder characterized by painful, unpredictable, recurrent inflammatory attacks affecting the hands, feet, face, abdomen, genitourinary tract, and larynx. The prevalence of HAE is uncertain, but is estimated to be about 1 case per 50,000 people, with no known differences between racial groups. HAE is caused by a deficiency (Type I) or dysfunction (Type II) of C1-INH levels, which inhibits PKa, bradykinin, and other serine proteases in the blood. Individuals with hereditary angioedema (HAE) lack C1-INH, resulting in excessive bradykinin production, which in turn causes painful, debilitating, and potentially fatal swelling attacks. If left untreated, HAE can result in a high mortality rate of up to 40%, primarily due to upper airway obstruction. [Overview of the project]

[0135] Compounds expressly disclosed herein may be claimed as individual compounds, including those without reference to stereochemistry.

[0136] C. Pharmaceutical Compositions In another aspect, the present invention provides compounds according to the present disclosure, for example, compounds of formula (I) to (VI-c), or pharmaceutical compositions comprising compounds of formula (I) to (VI-c) or compounds named in combination with, for example, pharmaceutically acceptable excipients (e.g., carriers).

[0137] The pharmaceutical composition comprises optical isomers, diastereomers, or pharmaceutically acceptable salts of the inhibitors disclosed herein. The compounds of formulas (I) to (VI-c) contained in the pharmaceutical composition may be covalently bonded to the support portion as described above. Alternatively, the compounds of formulas (I) to (VI-c) contained in the pharmaceutical composition may not be covalently bonded to the support portion.

[0138] As used herein, “pharmaceutically acceptable carrier” refers to a pharmaceutically and physiologically acceptable organic or inorganic carrier substance that does not react adversely with pharmaceutical excipients, e.g., activators, and is suitable for enteral or parenteral administration. Suitable pharmaceutically acceptable carriers include water, salt solutions (e.g., Ringer's solution), alcohol, oil, gelatin, and carbohydrates such as lactose, amylose, or starch, fatty acid esters, hydroxymethylcellulose, and polyvinylpyrrolidine. Such preparations may be sterilized and, if necessary, mixed with adjuvants, e.g., lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts to affect osmotic pressure, buffers, colorants, and / or fragrances, etc., that do not react adversely with the compounds of the present invention.

[0139] The compounds of the present invention can be administered to a subject alone or in combination. Co-administration means administering the compounds individually or in combination (two or more compounds) simultaneously or sequentially. The preparations may also be combined with other active agents as needed (for example, to reduce metabolic degradation).

[0140] In some embodiments, a test agent as described herein may be incorporated into a pharmaceutical composition for administration by methods known to those skilled in the art and by methods described herein for the provided compound.

[0141] D. Pharmaceuticals The compounds of the present invention can be prepared in a wide variety of oral, parenteral, and topical dosage forms and can be administered in a wide variety of oral, parenteral, and topical dosage forms. Accordingly, the compounds of the present invention can be administered by injection (e.g., intravenously, intramuscularly, intradermally, subcutaneously, intraduodenally, or intraperitoneally). In some embodiments, the compounds of the present disclosure are administered orally. The compounds described herein can also be administered by inhalation, for example, intranasally. In addition, the compounds of the present invention can be administered percutaneously. It is also conceivable that multiple routes of administration (e.g., intramuscularly, orally, percutaneously) may be used to administer the compounds of the present invention. Accordingly, the present invention also provides pharmaceutical compositions comprising a pharmaceutically acceptable carrier or excipient and one or more compounds of the present invention.

[0142] For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers may be solid or liquid. Examples of solid preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. The solid carrier may be one or more substances that can also function as diluents, flavoring agents, binders, preservatives, tablet disintegrants, or encapsulating materials.

[0143] In the powder form, the carrier is a micronized solid in a mixture with the micronized active ingredient. In the tablet form, the active ingredient is mixed in a suitable ratio with a carrier having the required binding properties and compressed into the desired shape and size.

[0144] Powders and tablets preferably contain 5% to 70% of the active compound. Suitable carriers include magnesium carbonate, magnesium stearate, talc, sugars, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, low-melting-point waxes, and cocoa butter. The term “preparation” is intended to include formulations of the active compound with encapsulating material as a carrier, in which the active ingredient is surrounded by a carrier, either with or without other carriers, thereby providing a capsule in which the carrier associates with the active ingredient. Similarly, cachets and licks are included. Tablets, powders, capsules, pills, cachets, and licks can be used as solid dosage forms suitable for oral administration.

[0145] To prepare the suppositories, a mixture of low-melting-point waxes, such as fatty acid glycerides or cocoa butter, is first melted, and the active ingredients are uniformly dispersed therein by stirring or other means. The melted homogeneous mixture is then poured into a mold of a convenient size and allowed to cool, thereby solidifying.

[0146] Liquid preparations include solutions, suspensions, and emulsions, such as water or water / propylene glycol solutions. For parenteral injections, the liquid preparation may be formulated as a solution of polyethylene glycol aqueous solution.

[0147] Where parenteral administration is required or desired, particularly suitable mixtures for the compounds of the present invention are injectable sterile solutions, preferably oily or aqueous solutions, and suspensions, emulsions, or inserts (including suppositories). In particular, suitable carriers for parenteral administration include aqueous dextrose, physiological saline, pure water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil, and polyoxyethylene block polymers. Ampoules provide a convenient unit dose. The compounds of the present invention may also be incorporated into liposomes or administered via transdermal pumps or patches. Suitable pharmaceutical mixtures for use in the present invention include, for example, those described in Pharmaceutical Sciences (17th Ed., Mack Pub. Co., Easton, PA) and WO96 / 05309, both of which are incorporated herein by reference.

[0148] Aqueous solutions suitable for oral use can be prepared by dissolving the active ingredient in water and, if desired, adding suitable colorants, flavorings, stabilizers, and thickeners. Aqueous suspensions suitable for oral use can be prepared by dispersing the pulverized active ingredient in water with a viscous material, such as natural or synthetic gum, resin, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents.

[0149] This also includes solid preparations intended to be converted into liquid preparations for oral administration immediately before use. Such liquid preparations include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active ingredient, colorants, flavorings, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solvents, and the like.

[0150] Pharmaceutical preparations are preferably in unit dosage forms. In such a form, the preparation is subdivided into unit doses containing an appropriate amount of the active ingredient. A unit dosage form may be a packaged preparation, and the package contains individual amounts of the preparation, such as packaged tablets, capsules, and powder in vials or ampoules. Alternatively, a unit dosage form may be the capsule, tablet, cachet, or lollipop itself, or it may be any appropriate number of such in the packaged form.

[0151] The amount of the active ingredient in a unit dose preparation may be changed or adjusted depending on the specific use and potency of the active ingredient. The composition may also contain other suitable therapeutic agents as needed.

[0152] Some compounds may have limited water solubility and therefore may require a surfactant or other suitable co-solvent in the composition. Examples of such co-solvents include polysorbates 20, 60, and 80; Pluronic F-68, F-84, and P-103; cyclodextrin; and polyoxyl 35 castor oil. Such co-solvents are typically used at levels between about 0.01% by weight and about 2% by weight.

[0153] To reduce variability during the distribution of a formulation, to decrease the physical separation of components in the suspension or emulsion formulation, and / or to otherwise improve the formulation, a viscosity higher than that of a simple aqueous solution may be desirable. Examples of such viscosity-increasing agents include polyvinyl alcohol, polyvinylpyrrolidone, methylcellulose, hydroxypropyl methylcellulose, hydroxyethylcellulose, carboxymethylcellulose, hydroxypropylcellulose, chondroitin sulfate and its salts, hyaluronic acid and its salts, and combinations thereof. Such agents are typically used at levels between about 0.01% by weight and about 2% by weight.

[0154] The compositions of the present invention may further contain components that provide sustained release and / or comfort. Such components include high molecular weight anionic mucus-mimicking polymers, gelling polysaccharides, and micronized drug carrier substrates. These components are described in more detail in U.S. Patents 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The entirety of these patents is incorporated herein by reference for all purposes.

[0155] E. Effective dosage The pharmaceutical compositions provided by the present invention include compositions containing an active ingredient in a therapeutically effective amount, i.e., an amount effective to achieve its intended use. The actual amount effective for a particular use depends, in particular, on the condition being treated. For example, when administered in a method of treating HAE, such a composition contains an amount of the active ingredient effective to achieve the desired result (e.g., inhibiting PKa in the subject and / or reducing the amount of bradykinin).

[0156] The dosage and frequency (single or multiple doses) of the compound administered may vary depending on various factors, including the route of administration; the recipient's size, age, sex, health status, weight, body mass index, and diet; the nature and severity of the symptoms of the disease being treated (e.g., a disease responding to PKa inhibition); the presence of other diseases or other health-related problems; the type of concomitant treatment; and complications from any disease or treatment plan. Other treatment plans or agents may be used in conjunction with the methods and compounds of the present invention.

[0157] For any provided compound or test agent, the therapeutically effective dose can first be determined by a cell culture assay. The target concentration is the concentration of the active compound(s) that can reduce PKa enzyme activity, for example, when measured using the method described.

[0158] The therapeutically effective dose for use in humans can be determined from animal models. For example, the human dose can be formulated to achieve a concentration that has been found to be effective in animals. The human dose can be adjusted, as described above, by monitoring PKa inhibition and adjusting the dose upward or downward.

[0159] The dosage may be modified depending on the patient and the requirements of the compound used. In the context of the present invention, the dose administered to a patient must be sufficient to produce a beneficial therapeutic response over time in the patient. The size of the dose is also determined by the presence, nature, and degree of any adverse side effects. In some embodiments, the compounds of this disclosure or pharmaceutical compositions containing them are provided as unit doses.

[0160] In one embodiment, the compounds provided herein exhibit one or more pharmacokinetic (PK) properties (e.g., C) compared to a reference compound. max t max , C min t 1 / 2It shows improvements in AUC, CL, bioavailability, etc. In some embodiments, the reference compound is a PKa inhibitor known in the art. In some embodiments, the reference compound is a PKa inhibitor selected from those disclosed in PCT Publication WO2019 / 178129.

[0161] F. Treatment Method This disclosure provides compounds and pharmaceutical compositions containing them for use in pharmaceuticals, i.e., for use in treatment. This disclosure further provides the use of any of the compounds described herein to inhibit the activity of PKa, which is beneficial for the treatment of PKa-mediated diseases and conditions. An example of a PKa-mediated disorder is edema, which refers to swelling of the whole body or part thereof of a subject resulting from inflammation or damage when small vessels become leaky and release fluid into surrounding tissue. In some examples, edema is HAE. In other examples, edema occurs in the eye (e.g., diabetic macular edema (DME)). This disclosure provides methods for inhibiting the activity of PKa. In certain embodiments, this application provides a method for inhibiting the activity of PKa in vitro by contacting any of the compounds described herein with PKa molecules in a sample (e.g., a biological sample). In certain embodiments, this application provides a method for inhibiting the activity of PKa in vivo by delivering an effective amount of any of the compounds described herein to a subject requiring treatment through a preferred route.

[0162] In certain embodiments, the method involves administering one of the compounds described herein or a pharmaceutically acceptable salt thereof to a subject that needs administration (e.g., a human patient (e.g., one with edema)). In certain embodiments, the method involves administering a compound of formula (I) to (VI-c) or a pharmaceutically acceptable salt or composition thereof to a subject that needs them. In some embodiments, the method involves administering a pharmaceutical composition containing a compound of formula (I) to (VI-c) or a pharmaceutically acceptable salt thereof to a subject that needs them.

[0163] In certain embodiments, the subjects treated by any of the methods described herein are human patients who have, are suspected of having, or are at risk of having edema, such as HAE or diabetic macular edema (DME). Subjects with edema may be identified by routine medical tests, such as clinical tests. Subjects suspected of having edema may exhibit one or more symptoms of the disease / disorder. Subjects at risk of edema may have one or more disease-related risk factors, such as a C1-INH deficiency for HAE.

[0164] In certain embodiments, methods for alleviating one or more symptoms of HAE in human patients suffering from HAE attacks are provided herein. Such patients may be identified by standard medical procedures. One or more effective doses of the compounds provided may be administered to the human patient via a preferred route, for example, the routes described herein. The compounds described herein may be used alone or in combination with other anti-HAE agents, such as C1 esterase inhibitors (e.g., Cinryze® or Berinert®), PKa inhibitors (e.g., ecalantide or lanadermab), or bradykinin B2 receptor antagonists (e.g., Firazyr®).

[0165] In other embodiments, methods for reducing the risk of HAE attacks in human HAE patients in a sedated state are provided herein. Such patients may be identified based on various factors, including a history of HAE attacks. One or more effective doses of the compounds may be administered to the human patient via a preferred route, for example, the routes described herein. The compounds described herein may be used alone or in combination with other anti-HAE agents, such as C1 esterase inhibitors (e.g., Cinryze® or Berinert®), PKa inhibitors (e.g., ecalantide or lanadermab), or bradykinin B2 receptor antagonists (e.g., Firazyr®).

[0166] In further embodiments, prophylactic treatment for HAE in human patients at risk of HAE attacks using one or more of the compounds described herein is provided herein. In some embodiments, patients suitable for prophylactic treatment for HAE are human subjects who have HAE (e.g., have a history of HAE attacks). In some embodiments, patients suitable for such prophylactic treatment are human subjects whom a physician determines to be worthy of a prophylactic approach based on their history of HAE attacks (e.g., human subjects who have experienced a certain average number of attacks over a period of time (including, in non-limiting examples, one, two, or more attacks per month)). Alternatively, patients suitable for prophylactic treatment may be human subjects who do not have a history of HAE attacks but have one or more risk factors for HAE (e.g., a family history, a genetic defect in the C1-INH gene). Such prophylactic treatment may require one of the compounds described herein as the sole active agent, or it may require additional anti-HAE agents, e.g., those described herein.

[0167] In certain embodiments, methods for preventing or reducing edema in the eye of a subject (e.g., a human patient) are provided herein. In some examples, the human patient is a diabetic patient who has, is suspected of having, or is at risk of having diabetic macular edema (DME). DME is a proliferative diabetic retinopathy characterized by swelling of the retinal layer, neovascularization, vascular leakage, and retinal thickening, resulting from leakage of fluid from blood vessels in the macula. To carry out this method, an effective amount of one or more of the compounds described herein or a pharmaceutically acceptable salt thereof can be delivered to the eye of a subject requiring treatment. For example, the compounds can be delivered topically by intraocular or intravitreal injection. The subject may be treated with the compounds described herein either as the sole active agent or in combination with another treatment method for DME. Non-exclusive examples of treatments for DME include laser photocoagulation, steroids, VEGF pathway-targeting agents (e.g., Lucentis® (ranibizumab) or Eylea® (aflibercept)), and / or anti-PDGF agents.

[0168] In certain embodiments, the methods disclosed herein involve administering an effective amount of a compound of formula (I) to (VI-c) or a pharmaceutically acceptable salt or composition thereof to a target. In some embodiments, the effective amount is a therapeutically effective amount. In some embodiments, the effective amount is a prophylactically effective amount.

[0169] In certain embodiments, the subject being treated is an animal. The animal may be of any sex and at any developmental stage. In certain embodiments, the subject is a mammal. In certain embodiments, the subject being treated is a human. In certain embodiments, the subject is a domesticated animal, such as a dog, cat, cow, pig, horse, sheep, or goat. In certain embodiments, the subject is a companion animal, such as a dog or cat. In certain embodiments, the subject is a domesticated animal, such as a cow, pig, horse, sheep, or goat. In certain embodiments, the subject is a zoo animal. In other embodiments, the subject is a research animal, such as a rodent (e.g., mouse, rat), dog, pig, or non-human primate. In certain embodiments, the animal is a genetically modified animal. In certain embodiments, the animal is a transgenic animal.

[0170] Certain methods described herein may include administering one or more additional pharmaceuticals in combination with the compounds described herein. The additional pharmaceuticals may be administered simultaneously with the compounds of formulas (I) to (VI-c) or at different times. For example, the compounds of formulas (I) to (VI-c) and any additional pharmaceuticals may be administered on the same or different schedules. All or some doses of the compounds of formulas (I) to (VI-c) may be administered before all or some doses of the additional pharmaceuticals, after all or some doses of the additional pharmaceuticals, within the administration schedule of the additional pharmaceuticals, or in combination thereof. The timing of administration of the compounds of formulas (I) to (VI-c) and the additional pharmaceuticals may vary depending on the additional pharmaceuticals.

[0171] In certain embodiments, additional pharmaceuticals include agents useful in the treatment of edema, such as HAE or DME. Examples of such agents are provided herein.

[0172] Furthermore, the use of the compounds of this disclosure for the manufacture of pharmaceuticals for the conditions / diseases disclosed herein is also provided.

[0173] In the context of this specification, “comprising” should be interpreted as “including.” Embodiments of the present invention that include a particular characteristic / element are also intended to extend to alternative embodiments that “consist of” or “essentially consist of” the relevant element / characteristic. Where technically appropriate, embodiments of the present invention can be combined.

[0174] Technical references, such as patents and applications, are incorporated herein by reference.

[0175] Any embodiment specifically and expressly enumerated herein may, alone or in combination with one or more further embodiments, form the basis of a disclaimer.

[0176] The background technical sections of this specification contain relevant technical information that may be used as a basis for modifications. Subject headings are used to divide the document into sections and are not intended to be used to interpret the meaning of the disclosure provided herein.

[0177] This specification claims priority to U.S. Provisional Patent Application No. 63 / 162,483, filed on 17 March 2021 and incorporated herein by reference. This application may be used as the basis for amendments to this specification, particularly with respect to the chemical structures disclosed herein. [Examples]

[0178] IV. Examples In certain embodiments, the examples describe compounds containing one or more stereocenters, where a particular stereocenter is designated as "S*" or "R*". In either case, the "*" notation generally indicates that the exact configuration is unknown (for example, in the case of a compound with a single stereocenter, the notation R*- or S*- indicates that either an R-isomer or an S-isomer was isolated, but the configuration of the stereocenter of the particular isomer that was isolated was not determined).

[0179] It will be understood that the compounds described in the examples may contain two or more stereocenters. As stated above, single stereoisomers of the compounds of the present invention, as well as enantiomer mixtures, diastereomer mixtures, and geometric (or conformational) mixtures, are within the scope of the present invention. When two or more "S*" or "R*" appear in a pair of parentheses within a particular compound name (e.g., "(1S*,2S*)"), it will be understood that the S* configuration and / or R* configuration are relative to each other. For example, it will be understood that a compound indicated as "(1S*,2S*)-" or "(1R*,2R*)-" clearly refers to either the "(1S,2S)-" isomer or the "(1R,2R)-" isomer, but not the "(1S,2R)-" or "(1R,2S)-" isomer. Furthermore, compounds denoted as "rac-(1S*,2S*)-" or "rac-(1R*,2R*)-" will be understood to include racemic mixtures of the "(1S,2S)-" and "(1R,2R)-" isomers. Similarly, compounds denoted as "(1S*,2R*)-" or "(1R*,2S*)-" will be understood to clearly refer to either the "(1R,2S)-" isomer or the "(1S,2R)-" isomer, but not to the "(1S,2S)-" or "(1R,2R)-" isomer. In addition, compounds denoted as "rac-(1R*,2S*)-" or "rac-(1S*,2R*)-" will be understood to include racemic mixtures of the "(1R,2S)-" and "(1S,2R)-" isomers. In certain embodiments, the examples include schemes showing compounds having one or more stereocenters. In some embodiments, a number is displayed adjacent to the stereocenter after the symbol "&". In such cases, it is understood that the position includes a mixture of both configurations (e.g., R- and S-).

[0180] In some embodiments, a number appears adjacent to the stereocenter after the term "or". In such cases, it is understood that either the "R-" or "S-" isomer is indicated, and a specific isomer has not been determined.

[0181] In some embodiments, the numbering following the symbol "&" or the term "or" refers to the relationship between one stereocenter and another in the compound. For example, if two stereocenters in a compound are each numbered the same (e.g., two instances of "&1"), the arrangements are understood to be relative to each other (e.g., if the structure is described as (S,S) and both stereocenters are indicated by "&1", it is understood that a mixture of (S,S) and (R,R) isomers is included, but no (S,R) or (R,S) isomers are included). However, if each stereocenter is numbered differently (e.g., one instance of "&1" and one instance of "&2"), the arrangements can be independent of each other (e.g., if the structure is described as (S,S) and one stereocenter is indicated by "&1" and the other by "&2", it is understood that a mixture of (S,S), (S,R), (R,S), and (R,R) isomers is included).
