Abstract
Description
[Technical Field]
[0001] This invention relates to a novel compound that can simultaneously inhibit ANO1 (Anoctamin 1) and EGFR (epidermal growth factor receptor), and a method for producing the same.
[0002] This invention claims priority based on Korean Patent Application No. 10-2023-0073989, filed on June 9, 2023, and Korean Patent Application No. 10-2024-0074031, filed on June 5, 2024, and all contents disclosed in the specifications and drawings of the said applications are incorporated herein by reference. [Background technology]
[0003] Glioblastoma is a primary malignant brain tumor that occurs in adults. If left untreated after diagnosis, death occurs within 3 to 6 months, and even with all available treatments, the average survival time is only 12 to 14 months. It is an extremely aggressive disease. In South Korea, approximately 12,000 brain tumors are diagnosed each year. Of these, about 9,000 are benign tumors such as meningiomas or pituitary adenomas, and about 2,000 are diagnosed as malignant tumors. Of the malignant tumor patients each year, approximately 630 are diagnosed with glioblastoma.
[0004] Glioblastomas, which originate from glial cells in brain tissue, grow invasively into surrounding brain tissue, resulting in unclear tumor boundaries and a wider spread than what is visible to the naked eye during radiological examinations or surgery. Due to functional limitations of the brain, glioblastomas are often located in areas that cannot be surgically removed, and complete remission is not achieved with radiation therapy. Furthermore, the presence of the blood-brain barrier makes it difficult for anticancer drugs to penetrate the brain, resulting in a limited number of effective anticancer drugs and making glioblastoma an extremely difficult disease to treat with a poor prognosis. Currently, temozolomide is used as the basic treatment for glioblastoma, but long-term treatment leads to side effects and resistance, making continued treatment difficult. Moreover, despite many advances in modern medicine and the development of new drugs, no new treatments have yet emerged.
[0005] One of the oncogenes that frequently undergoes genetic mutations in glioblastoma patients is EGFR (epidermal growth factor receptor). EGFR has physiological importance, and mutations in EGFR are observed in more than half of patients. When EGF or TNF-α binds to EGFR, various signal transduction processes occur within the cell. However, overexpression or hyperactivation of EGFR induces excessive cell proliferation and other complications, ultimately leading to cancer. Among EGFR mutations, EGFRvIII is characterized by the deletion of amino acids 6 to 273 and is a protein specifically expressed only in cancer cells. EGFRvIII was first discovered in glioblastoma, but has also been confirmed in cancers of other tissues.
[0006] It has been reported that volume regulation of cancer cells by chloride ion channel proteins such as Anoctamin 1 (ANO1) and the CLC (chloride channel) family is important in the migration and metastasis of glioblastoma cells. The ANO1 protein is involved in various physiological functions (pain regulation, blood pressure regulation, brain nerve development, water secretion regulation, etc.), and its antitumor effects have been reported in particular in various cancer cells (breast cancer, head and neck cancer, prostate cancer, pancreatic cancer, lung cancer, etc.). Inhibition of the ANO1 protein in breast cancer produced an anticancer effect via CaMK2 signaling. Furthermore, while the expression level of ANO1 is remarkably low in the normal brain, the ANO1 protein is overexpressed in glioblastoma, and it has been reported that suppressing ANO1 activity inhibits glioblastoma cell migration and metastasis, and suppresses tumor growth in animal models. In addition, it has been reported that suppressing ANO1 in glioblastoma stem cells induces the degradation of epidermal growth factor receptor mutant 3 (EGFRvIII) protein. These findings suggest that inhibiting the ANO1 protein could be a therapeutic strategy for various EGFR mutation-related cancers, including glioblastoma.
[0007] Thus, both the ANO1 protein and EGFR have potential as targets for anti-cancer therapy. However, to date, no substance has been found that can exert a superior antitumor effect through the dual inhibition of both the ANO1 protein and EGFR. [Overview of the project] [Problems that the invention aims to solve]

[0141] Another object of the present invention is to provide a pharmaceutical composition for the prevention or treatment of brain tumors, comprising as an active ingredient one or more compounds selected from the group consisting of compounds represented by the chemical formulas 1 to 6 or a pharmaceutically acceptable salt thereof.
[0142] The compounds according to the present invention are inhibitors of the calcium-dependent chloride channel Anoctamine 1 (ANO1), and can be used for the prevention, improvement, and / or treatment of brain tumors. In particular, the compounds according to the present invention are characterized by exhibiting excellent anticancer effects by simultaneously suppressing the expression or activity of EGFR and ANO1. The aforementioned preventive and / or therapeutic effects on brain tumors include not only the effect of suppressing the growth of brain tumor cells, but also the effect of suppressing the progression and worsening of brain tumors due to migration, invasion, metastasis, etc.
[0143] In this invention, "EGFR (epidermal growth factor receptor)" is a transmembrane glycoprotein that is a member of the protein kinase superfamily and is a receptor for the epidermal growth factor family of proteins. EGFR is a major regulator of cell growth, and when its ligand, epidermal growth factor (EGF), binds to EGFR, the receptor undergoes dimerization and tyrosine autophosphorylation, inducing cell proliferation. Overexpression (amplification) or overactivity of EGFR is frequently observed in various cancers such as anal cancer, head and neck cancer, and glioblastoma, but EGFR-related somatic mutations cause persistent activation of EGFR and induce uncontrolled cell division. In particular, EGFR gene rearrangements and EGFR gene amplification are observed in various cancers. Among these, the most common extracellular domain mutation is EGFRvIII. EGFRvIII mutations are characterized by the deletion of over 801 base pairs in exons 2-7 of the EGFR gene, resulting in the expression of EGFR protein with 267 amino acids missing from the extracellular domain. Unlike normal EGFR, which is activated only when a ligand binds, the mutated EGFR maintains a persistently activated state (PCT gain of function mutation). EGFRvIII is frequently observed, particularly in glioblastoma.
[0144] In this invention, "Anoctamin 1 (ANO1)" is also called "transmembrane protein 16A (TMEM16A)," and is a calcium-activated chloride ion channel (Cl -ANO1 is a neurotransmitter channel. ANO1 is expressed in a variety of normal cells, including epithelial cells, smooth muscle cells, vascular endothelial cells, and neurons, and plays diverse physiological roles by regulating fluid secretion, muscle contraction, and pain sensation. However, ANO1 is known to be associated with cancer invasiveness and poor prognosis in brain tumors, including glioblastoma. In fact, it has been reported that overexpression of ANO1 promotes signaling pathways that stimulate proliferation and migration in cancer cells, and that suppression of ANO1 inhibits the migration and growth of cancer cells. High expression of ANO1 is also thought to be associated with high expression of EGFR and STAT3, and it is known that suppression of ANO1 can improve the response of head and neck squamous cell carcinoma to EGFR / HER2 targeted therapy. Therefore, ANO1 is attracting attention as a target for cancer treatment, but an ANO1 inhibitor that actually exhibits excellent anticancer effects has not yet been found. The compounds according to the present invention have been confirmed to effectively suppress ANO1 expression in brain tumor cells and to suppress the migration, proliferation, and metastasis of brain tumor cells more potently than conventionally known ANO1 inhibitors. Therefore, they can be used for the prevention, treatment, and suppression of metastasis of brain tumors. Furthermore, previous research on improving the efficacy of EGFR / HER2 targeted therapy by ANO1 suppression suggests that the compounds according to the present invention can enhance the responsiveness of brain tumor cells to EGFR / HER targeted therapy and suppress the development of resistance through their ANO1 inhibitory effect.
[0145] In particular, the compounds according to the present invention simultaneously suppress the expression of EGFR along with ANO1 in brain tumor cells, and can exert an even more potent anticancer effect through the simultaneous suppression of ANO1 and EGFR. The relationship between ANO1 and EGFR is well known, and it has been reported that upward regulation of ANO1 is related to the EGFR signaling pathway and has a significant impact on phosphorylated proteome remodeling after epidermal growth factor (EGF) stimulation. Furthermore, in cancer cells, ANO1 can form a functional complex with EGFR to jointly regulate cell proliferation. Therefore, by simultaneously suppressing EGFR and ANO1 using the compounds of the present invention, the growth of brain tumors can be inhibited even more effectively.
[0146] Furthermore, ANO1 is known to be overexpressed in cancer cells and contribute to cancer cell migration and tumor metastasis, and EGFR-mediated signaling is also known to generate a tumor microenvironment that is useful for tumor metastasis. Therefore, the compounds according to the present invention can effectively suppress brain tumor metastasis through the simultaneous suppression of ANO1 and EGFR. The term "metastasis" refers to the state in which a malignant tumor has spread to other tissues away from the organ in which it originated. Therefore, the compositions according to the present invention can suppress brain tumor metastasis and prevent and treat the spread of brain tumors throughout the body.
[0147] The compounds according to the present invention or their pharmaceutically acceptable salts can be used for various cancer prevention or treatment applications.
[0148] In this invention, "tumor" is used synonymously with "cancer" and refers to a condition typically characterized by uncontrolled cell growth, migration, and proliferation. Preferably, the cancer according to this invention is a brain tumor. The cancer according to this invention includes primary and recurrent cancers and encompasses all benign and malignant tumors. In this invention, the brain tumor is all tumors occurring within the skull and is not limited to specific types, but includes all tumors occurring in the brain and surrounding structures. In this invention, the brain tumor includes primary brain tumors, recurrent brain tumors, and metastatic brain tumors. Furthermore, the brain tumor includes, but is not limited to, astrocytomas, malignant astrocytomas, glioblastomas, meningiomas, pituitary adenomas, schwannomas, acoustic neuromas, and craniopharyngiomas.
[0149] In particular, the cancer according to the present invention may be a brain tumor that is expected to be improved or treated by simultaneously inhibiting ANO1 and EGFR. Preferably, the cancer according to the present invention may be a brain tumor associated with one or more mutations selected from the group consisting of EGFR (Epidermal growth factor receptor) and ANO1 (Anoctamin 1). That is, the cancer according to the present invention may be a brain tumor having mutations in EGFR and / or ANO1. The mutations in EGFR and / or ANO1 include amplification of the EGFR and / or ANO1 genes, overexpression of the protein, overactivity of the protein, and sustained activation of the protein. That is, the cancer according to the present invention may be a brain tumor in which the expression or activity of EGFR and / or ANO1 is even higher compared to normal cells. Alternatively, the cancer according to the present invention may be a brain tumor in which the activated state of EGFR and / or ANO1 persists. Since the compounds according to the present invention can simultaneously suppress the expression and activity of ANO1 and EGFR, they can exhibit particularly excellent anticancer effects against brain tumors accompanied by mutations in EGFR and / or ANO1.
[0150] Alternatively, the cancer according to the present invention may be a brain tumor accompanied by an EGFRvIII (epidermal growth factor receptor variant III) mutation. The EGFRvIII mutation is a mutation in which amino acids 6-273 of EGFR are deleted (or exons 2-7 are deleted), and is characterized by its ability to remain activated even without ligand (EGF) binding. EGFRvIII is specifically expressed only in cancer cells and is found in approximately 30% of glioblastomas.
[0151] The compounds according to the present invention can exert one or more effects from the group consisting of the following: (a) Suppress the proliferation or growth of brain tumor cells; (b) Suppress the migration of brain tumor cells; (c) Suppress the metastasis of brain tumors; (d) Suppressing resistance of brain tumors to anticancer drugs; and (e) It enhances the responsiveness of brain tumor cells to anticancer drugs.
[0152] Based on specific examples, the inventors confirmed that brain tumor cells treated with the compound according to the present invention exhibited suppressed proliferation, migration, and metastasis (penetration), demonstrating that the anticancer effect of the compound is more potent than that of conventionally known ANO1 inhibitors (CaCCinh-A01).
[0153] Furthermore, since the compounds according to the present invention can simultaneously inhibit ANO1 and EGFR (i.e., double inhibition), they can exhibit even better anticancer effects compared to ANO1 or EGFR inhibitors alone. In particular, they can suppress the development of resistance in cancer cells to anticancer drugs through ANO1 inhibition, thereby enhancing the anticancer effect of the anticancer drug. For example, the inventors have confirmed through experiments that the ANO1 inhibitory effect of the compounds according to the present invention is not only superior to that of the conventional ANO1 inhibitor CaCCinh-A01, but also that their anticancer effect is superior to that of the ANO1 inhibitor CaCCinh-A01, the EGFR inhibitor Osimertinib, and the combination of Osimertinib and CaCCinh-A01.
[0154] In one embodiment of the present invention, the anticancer agents described in (d) and (e) above may be, but are not limited to, targeted anticancer agents against tyrosine kinase. In the present invention, "targeted anticancer agent" means a formulation that exhibits an anticancer effect by targeting proteins or genes that are specifically altered in cancer cells or cancer tissue and interfering with molecular activities involved in cancer growth and development. Preferably, the tyrosine kinase may be one or more selected from the group consisting of EGFR (epidermal growth factor receptor), ALK (anaplastic lymphoma kinase), ROS1 (ROS Proto-Oncogene 1), BRAF (B-Raf Proto-Oncogene), HER2 (human epidermal growth factor receptor 2), RET (Ret Proto-Oncogene), NTRK1 (Neurotrophic Receptor Tyrosine Kinase 1), MET (Mesenchymal-Epithelial Transition factor), and NRG1 (Neuregulin 1). More preferably, the tyrosine kinase may be EGFR. The aforementioned EGFR includes normal EGFR and mutant EGFR (e.g., EGFRvIII).
[0155] In (e) above, the statement that the responsiveness of cancer cells to anticancer drugs is enhanced means that the suppression of cancer cell growth and migration by anticancer drugs is further enhanced.
[0156] In this invention, "enhancing the anticancer effect" refers to all effects that can ultimately strengthen the function of the anticancer drug. This includes not only enhancing the anticancer effects of the anticancer drug, such as inhibiting tumor growth, inhibiting tumor metastasis, and inhibiting tumor recurrence, but also enhancing the anticancer effect by suppressing the resistance and tolerance formation of cancer cells to the anticancer drug.
[0157] Therefore, the compounds according to the present invention can be used as compounds for co-administration with known anticancer agents (preferably targeted anticancer agents against tyrosine kinases) for the purpose of enhancing the anticancer effect of brain tumor anticancer agents.
[0158] For example, the present invention provides a pharmaceutical composition for the prevention or treatment of cancer (preferably brain tumors), comprising (i) one or more compounds selected from the group consisting of compounds represented by the chemical formulas 1 to 6 or a pharmaceutically acceptable salt thereof; and (ii) a targeted anticancer agent against EGFR as an active ingredient.
[0159] Furthermore, the present invention provides a pharmaceutical composition for enhancing the anticancer effect of an anticancer agent (preferably a brain tumor anticancer agent), comprising one or more compounds selected from the group consisting of compounds represented by the above chemical formulas 1 to 6, or a pharmaceutically acceptable salt thereof, as an active ingredient.
[0160] The composition according to the present invention is in the form of a mixture comprising the compound or a pharmaceutically acceptable salt thereof and a targeted anticancer agent against EGFR, and may also be in the form of a mixture for simultaneous administration of the compound or a pharmaceutically acceptable salt thereof and the targeted anticancer agent against EGFR.
[0161] Furthermore, the composition according to the present invention may be in the form of formulations containing the compound or a pharmaceutically acceptable salt thereof, and a targeted anticancer agent against EGFR, which are administered simultaneously, separately, or sequentially. In this case, the composition may be a combination-administered pharmaceutical composition for simultaneous or sequential administration, comprising a first pharmaceutical composition containing a pharmaceutically effective amount of the compound or a salt thereof as an active ingredient, and a second pharmaceutical composition containing a pharmaceutically effective amount of the targeted anticancer agent against EGFR as an active ingredient. In the case of sequential administration, the order of administration is not restricted, and the administration therapy can be appropriately adjusted according to the patient's condition, etc.
[0162] In other words, if the pharmaceutical composition is a pharmaceutical composition for combination administration for sequential administration, the composition can be administered such that the compound or a salt thereof ("first component") is administered first, followed by the targeted anticancer agent against EGFR ("second component"), and the reverse order is also possible.
[0163] Furthermore, when the compound according to the present invention is used in combination with an anticancer agent, the compound can be administered simultaneously, separately, or sequentially with the anticancer agent. Even when administered sequentially with the anticancer agent, the order of administration is not restricted, but the administration therapy can be appropriately adjusted depending on the type of cancer, the type of anticancer agent, the patient's condition, etc.
[0164] The content of the compound in the composition of the present invention can be appropriately adjusted depending on the symptoms of the disease, the progression of the symptoms, the patient's condition, etc. For example, it may be 0.0001 to 99.9% by weight or 0.001 to 50% by weight based on the total weight of the composition, but is not limited thereto.

[0204] [ka]
[0205] Steps 1, 2, and 3 were carried out identically to those for compound AON-MG23-01, but in Step 4, 1-(4-amino-3-methoxyphenyl)-N,N-dimethylpiperidine-4-amine was used instead of 2-methoxy-4-(4-(4-methylpiperazine-1-yl)piperidine-1-yl)aniline for synthesis.
[0206] Specifically, N-cyclopropyl-N-(2-((2,5-dichloropyrimidine-4-yl)amino)phenyl)methanesulfonamide (1.00 eq) synthesized in Step 3 was added to ethanol (EtOH), and 1-(4-amino-3-methoxyphenyl)-N,N-dimethylpiperidine-4-amine (1.00 eq) and trifluoroacetic acid (TFA, 1.95 eq) were added at room temperature.

[0207] The compounds according to the present invention were produced through the above steps, and their structural formulas are shown in Table 1 and Figure 1 below.
[0208] [Table 1]
[0209] 2. Confirmation of the cell proliferation inhibitory effect of the compound of the present invention on human glioblastoma cells. Human glioblastoma cell line U87-MG cells are placed in a 96-well plate in a 1x10 ratio. 4 Cells were seeded at a density of cells / well and cultured for 24 hours. Afterward, they were treated with DMSO as a control group and with either the compound AON-MG23-01 or AON-MG23-02 of the present invention, respectively, followed by 48 hours of culture. The compounds of the present invention were treated at various concentrations of 0, 1, 2, and 4 μM. 10 μl of CCK reagent was added to each treatment, followed by a 1-hour reaction, and then the absorbance was measured at 450 nm.
[0210] As a result, as shown in Figure 2, we were able to confirm that the compounds AON-MG23-01 or AON-MG23-02 of the present invention suppress the proliferation of U87-MG cells.
[0211] 3. Confirmation of the inhibitory effect of the compound of the present invention on cell migration in human glioblastoma cells. Human glioblastoma cell line U87-MG cells are placed on SPLScar Block (SPL) plates in an 8x10 ratio. 4 Cells were seeded at a density of cells / well and cultured for 24 hours. After 24 hours, blocks were removed, and cells were treated with either AON-MG23-01 or AON-MG23-02 of the present invention, respectively, and then cultured in a CO2 incubator at 37°C for 24 hours. The compounds of the present invention were administered at concentrations of 0, 1, 2, and 4 μM, respectively. Photographs were taken before and after culture, and the distance of cell migration was measured using ImageJ software. Based on these results, the suppression of cell migration was analyzed.
[0212] As a result, as shown in Figure 3, when the cells were treated with the compound AON-MG23-01 or AON-MG23-02 of the present invention at a concentration of 4 μM, cell migration was suppressed by more than 65% compared to the untreated control group.
[0213] 4. Confirmation of the effect of the compound of the present invention on inhibiting metastasis of human glioblastoma. Human glioblastoma cell line U87-MG is placed on top of a Matrigel-coated filter (Transwell invasion chambers, Corning) at 8x10. 4 After seeding at a density of cells / well, the cells were treated with the compound of the present invention (AON-MG23-01 or AON-MG23-02; 0, 1, 2, 4 μM), respectively, and cultured for 24 hours in a CO2 incubator at 37°C. After culturing, cells were fixed and stained using the Diff-Quick Stain Kit (Sysmex, Kobe, Japan). Stained cells were imaged under a microscope, counted using ImageJ software, and then statistically analyzed.
[0214] As a result, as shown in Figure 4, the group treated with the compound AON-MG23-01 or AON-MG23-02 of the present invention showed a reduced degree of penetration into Matrigel compared to the untreated control group, confirming that the metastatic potential of cancer cells was suppressed.
[0215] 5. Confirmation of the effects of the compounds of the present invention on ANO1 and EGFR protein expression in glioblastoma cell lines.
[0216] We investigated whether the compound of the present invention affects the expression of ANO1 and EGFR proteins in glioblastoma cell lines. Human glioblastoma cell line U87-MG was placed in a 60mm dish (1x10). 6Cells were seeded at a given density and cultured for 24 hours. Afterward, each cell was treated with the compound of the present invention (AON-MG23-01 or AON-MG23-02; 0, 1, 2, or 4 μM), and cultured for 48 hours. The cultured cells were harvested and lysed for Western blotting. Antibodies used for Western blotting included anti-ANO1 antibody (Abcam, ab53212), anti-pEGFR antibody (Cell Signaling, #4407S), anti-EGFR antibody (Cell Signaling, #4267S), and anti-αTubulin antibody (Santacruz, #SC-5286). Protein concentration was quantified using the BSA method (Protein Quantitation Assay, Bovine serum albumin assay) (Pierce, Cat.23225). After lysing the cells, the obtained proteins were subjected to 10% SDS-PAGE with the same amount (10 μg) to separate them by molecular weight. These proteins were then transferred to a PVDF membrane (Bio-rad) and treated with blocking buffer (5% Skim milk in Tris-buffered saline (TBS) buffer containing 0.1% Tween 20, TBS-T) at room temperature for 1 hour. Next, the PVDF membrane was treated with the primary antibody and reacted at 4°C for 16 hours. The PVDF membrane was washed three times with TBS-T after the reaction. Then, the PVDF membrane was reacted with a secondary antibody labeled with horseradish peroxidase at room temperature for 1 hour, and the membrane was visualized using an ECL kit (Bio-rad). The amount of each protein was quantified and analyzed using ImageJ software.
[0217] As a result, as shown in Figure 5, cells treated with the compound of the present invention showed significantly suppressed levels of ANO1 and EGFR compared to the untreated control group, and this protein expression suppression effect was dependent on the treatment concentration of the compound.
[0218] 6. Confirmation of the ANO1 activity inhibitory effect of the compound of the present invention in glioblastoma cell lines. Using patch clamp, the activity of calcium-dependent chloride ion channels by the compounds of the present invention was measured to confirm the inhibitory effect on ANO1 ion channel activity. For this purpose, patch clamp was performed on U87-MG cells expressing ANO1. The pipette solution was 146 CsCl, 5 Ca-EGTA-NMDG, 8 HEPES, 2 MgCl2, 10 sucrose (pH 7.3), and the bath solution was 50 NaCl, 10 HEPES, 3 KCl, 2 CaCl2, 2 MgCl2, 5.5 glucose (pH 7.3). After culturing U87-MG cells on a coverslip for 4 hours, they were treated with AON-MG23-01 or AON-MG23-02 for 1 hour (treated at concentrations of 0, 4, and 8 μM respectively). At this time, chloride ion channels were activated using 400 mM ATP and high-concentration calcium, and the current of calcium-dependent chloride ion channels in the range of -100 mV to +100 mV was measured.
[0219] As a result, as shown in Figure 6a, it was shown that the ANO1 activity in the group treated with the compound of the present invention was clearly decreased compared to the untreated control group. In particular, as shown in Figure 6b, it was shown that the current density in the group treated with the compound of the present invention at a membrane potential of +80 mV decreased by 50% or more compared to the untreated control group. The above results indicate that the compound of the present invention can inhibit the activity of ANO1, a calcium-dependent chloride ion channel, in glioblastoma cell line U87-MG cells.
[0220] 7. Comparison of the effect of inhibiting metastasis of the compound of the present invention, EGFR inhibitor, and ANO1 inhibitor in human glioblastoma Human glioblastoma cell line U87-MG was placed on the upper part of a filter coated with Matrigel (Transwell invasion chambers, Corning) at 6×10 4After seeding at a cell / well density, cells were treated with 4 μM of the compound AON-MG23-02 of the present invention, 4 μM of the EGFR inhibitor Osimertinib, 100 μM of the ANO1 inhibitor CaCCinh-A01, and a combination of 4 μM Osimertinib and 100 μM CaCCinh-A01. The cells were then cultured for 16 hours at 37°C in a CO2 incubator. After culturing, cells were fixed and stained using a Diff-Quick staining kit (Sysmex, Kobe, Japan). Stained cells were imaged under a microscope, counted using ImageJ software, and then statistically analyzed.
[0221] As a result, as shown in Figures 7a and 7b, the group treated with the compound AON-MG23-02 of the present invention showed a reduced degree of penetration into Matrigel compared to the untreated control group, the EGFR inhibitor-treated group, and the ANO1 inhibitor-treated group, and exhibited a similar translocation inhibitory effect to the group treated with a combination of the EGFR inhibitor and the ANO1 inhibitor.
[0222] 8. Comparison of the inhibitory effects of the compounds of the present invention, EGFR inhibitors, and ANO1 inhibitors on ANO1, EGFR, and pEGFR protein expression in glioblastoma cell lines.

Then, they were treated with 4 μM AON-MG23-02, 2 μM EGFR inhibitor Osimertinib, 100 μM ANO1 inhibitor CaCCinh-A01, and a combination of 2 μM Osimertinib and 100 μM CaCCinh-A01, followed by 48 hours of culture. After culturing, the cells were harvested and lysed for Western blotting. Antibodies used for Western blotting included anti-ANO1 antibody (Abcam, ab53212), anti-pEGFR antibody (Cell Signaling, #4407S), anti-EGFR antibody (Cell Signaling, #4267S), and anti-ACTIN antibody (sigma, #A2066). Protein concentrations were quantified using the BSA method (Protein Quantitation Assay, Bovine serum albumin assay) (Pierce, Cat.23225). After lysing the cells, the obtained proteins were subjected to 10% SDS-PAGE with an equal amount (10 μg) to separate the proteins by molecular weight. These proteins were then transferred to a PVDF membrane (Bio-rad) and treated with blocking buffer (5% Skim milk in Tris-buffered saline (TBS) buffer containing 0.1% Tween 20, TBS-T) at room temperature for 1 hour. Next, the PVDF membrane was treated with the primary antibody and reacted at 4°C for 16 hours. The PVDF membrane was then washed three times with TBS-T for 10 minutes each. Next, the PVDF membrane was reacted with a horseradish peroxidase-labeled secondary antibody at room temperature for 1 hour, followed by three more washes with TBS-T for 10 minutes each. The washed PVDF membrane was treated with an ECL kit (Thermo, West Pico Plus) and the reaction was visualized using a da Vinci-Q instrument (YOUNGIN lapplus). We used ImageJ software to quantify and analyze the amount of each protein.
[0223] As a result, as shown in FIGS. 8a and 8b, it was confirmed that the compound AON-MG23-02 of the present invention decreased ANO1, EGFR, and pEGFR protein expression compared to the untreated control group, the EGFR inhibitor treatment group, the ANO1 inhibitor treatment group, and the combined treatment group of the EGFR inhibitor and the ANO1 inhibitor.

Human glioblastoma cell line U87-MG was placed in a 60mm dish at a rate of 100x10 4Cells were seeded at a cell / dish density and cultured for 24 hours. Afterward, they were treated with 0, 8, 16, and 32 μM of AON-MG23-05, AON-MG23-06, AON-MG23-07, and AON-MG23-08 derivatives, respectively, and cultured for 48 hours.

Protein concentration was quantified using the BSA method (Protein Quantitation Assay, Bovine serum albumin assay) (Pierce, Cat.23225). After lysing the cells, the proteins obtained were separated by molecular weight by 10% SDS-PAGE using the same amount (10 μg). These proteins were then transferred to a PVDF membrane (Bio-rad) and treated with blocking buffer (5% Skim milk in Tris-buffered saline (TBS) buffer containing 0.1% Tween 20, TBS-T) at room temperature for 1 hour. Next, the PVDF membrane was treated with the primary antibody and reacted at 4°C for 16 hours. The PVDF membrane was then washed three times with TBS-T for 10 minutes each. Next, the PVDF membrane was reacted with a secondary antibody labeled with horseradish peroxidase at room temperature for 1 hour, followed by three more washes with TBS-T for 10 minutes each. The washed PVDF membrane was then treated with an ECL kit (Thermo, West Pico Plus) and the reaction was visualized using a da Vinci-Q instrument (YOUNGIN lapplus).

[0282] 3. Comparison of the metastasis-inhibiting effects of four derivatives of AON-MG23-02 in human glioblastoma. Human glioblastoma cell line U87-MG was seeded at a density of 8x10⁴ cells / well onto a Matrigel-coated filter (Transwell invasion chambers, Corning). The cells were then treated with 0, 8, 16, and 32 μM of the compound derivatives of the present invention, AON-MG23-05, AON-MG23-06, AON-MG23-07, and AON-MG23-08, respectively, and cultured for 24 hours at 37°C in a CO₂ incubator. After culturing, cells were fixed and stained using a Diff-Quick staining kit (Sysmex, Kobe, Japan). Stained cells were imaged under a microscope, counted using ImageJ software, and then statistically analyzed.
[0283] As a result, as shown in Figures 10a and 10b, the groups treated with derivatives AON-MG23-05, AON-MG23-06, AON-MG23-07, and AON-MG23-08 showed a reduced degree of penetration into Matrigel compared to the untreated control group, confirming the suppression of metastasis in human glioblastoma. The above description of the present invention is illustrative, and a person with ordinary skill in the art to which the present invention pertains will understand that it can be easily modified into other specific forms without altering the technical idea or essential features of the present invention. Therefore, the embodiments described above should be understood to be illustrative and not limiting in all respects. [Industrial applicability]
[0284] The novel compound of the present invention can not only be used as an ANO1 inhibitor, but can also simultaneously suppress ANO1 and EGFR in brain tumor cells. Therefore, it can be used as a dual-target anticancer agent for ANO1 and EGFR, and can also be utilized as a combination formulation for EGFR-targeted therapy. As such, it can be used in a variety of ways in the field of brain tumor prevention and treatment, and has industrial applicability.
