Description

[Technical Field]

[0001] The present invention relates to compounds that the applicant has discovered to be inhibitors of CD151. As a result of this activity, these compounds can be used to treat medical indications related to this transmembrane domain cell surface protein. Thus, the compounds can be applied to the treatment of cancer, as well as, for example, asthma, multiple sclerosis, and inflammatory bowel disease. The compounds can also be applied to the treatment of certain animal diseases related to CD151. [Background technology]

[0002] The past 200 years have seen significant advances in medical research, resulting in a dramatic increase in life expectancy due to the development of effective medical treatments for a significant number of diseases / conditions.

[0003] Nevertheless, there remains a continuing drive to provide treatments for diseases and conditions for which effective treatments are not available. Accordingly, there is significant research being conducted into biological targets that may be involved in many medical conditions of interest.

[0004] One area of ​​interest is the tetraspanins, a superfamily of four-transmembrane domain cell surface proteins that includes the tumor suppressor KAI1 / CD82 and tumor promoter CD151. Tetraspanins are expressed in a wide variety of cell types and have been implicated in cancer progression. In particular, tetraspanins may be involved in cell adhesion, cell motility, and tumor suppression or activation. Tetraspanins are thought to regulate their activity through the organization of cell surface membrane microdomains that facilitate interactions with a range of other proteins, such as integrins, immune receptors, and signaling molecules.

[0005] CD151 is a member of the tetraspanin superfamily that associates with integrins, membrane receptors, intracellular signaling molecules (such as PI4K and PKC), immunoglobulins, and other tetraspanins, and these tetraspanin-enriched microdomains (TEMs) act as molecular facilitators (Kumari S et al, Biomarkers in Cancer 2015;7:7-11).

[0006] CD151 is involved in wound healing, platelet aggregation, epithelial cell integrity, cell migration, angiogenesis, and tumor metastasis. Its expression is ubiquitous, but it is often overexpressed in cancer cells and is associated with cancer progression and metastasis.

[0007] Overexpression of CD151 has been associated with a wide range of common human cancers, including prostate cancer (Ang J et al., Cancer Epidemiol Biomarkers Prev 2004;13(11 Pt 1):1717-1721), breast cancer (Yang XH et al., Cancer Res 2008;68:3204-3213), pancreatic cancer (Zhu GH et al., Dig Dis Sci 2011;56:1090-1098), colon cancer (Hashida H et al., Br J Cancer 2003;89:158-167), and non-small cell lung cancer (Tokuhara T et al., Clin Cancer Res 2001;7:4109-4114). Other cancers in which CD151 is overexpressed include hepatocellular carcinoma (Ke AW et al, Hepatology 2009;49:491-503), intrahepatic cholangiocarcinoma (Huang XY et al, Cancer 2010;116:5440-5451), renal cell carcinoma (Yoo SH et al, Histopathology 2011;58:191-197), endometrial carcinoma (Voss MA et al, Br J Cancer 2011;104:1611-1618), esophageal carcinoma (Suzuki S et al, Ann Surg Oncol 2011;18:888-893), squamous cell carcinoma (Li Q et al, Oncogene 2013;32:1772-1783), and glioblastoma multiforme (Lee D et al, J Surg Oncol 2013;107:646-652), melanoma (Saito N et al, Pigment Cell Melanoma Res 2009;22:601-610), and ovarian cancer (Medrano M et al, Cell Rep 2017;18:2343-2358).

[0008] Several non-cancerous medical conditions are also associated with CD151 overexpression, such as asthma (Qiao Y et al, J Allergy Clin Immunol 2017;139:82-92), inflammatory bowel disease (Zelman-Toister E et al, Inflamm Bowel Dis 2016;22:257-267), and multiple sclerosis (Lombardo, SD; Mazzon, E.; Basile, MS; Campo, G.; Corsico, F.; Presti, M.; Bramanti, P.; Mangano, K.; Petralia, MC; Nicoletti, F.; Fagone, P. Modulation of Tetraspanin 32 (TSPAN32) Expression in T Cell-Mediated Immune Responses and in Multiple Sclerosis. Int. J. Mol. Sci. 2019, 20, 4323. and cytomegalovirus infection (Hochdorfer D et al, Journal of Virology 2016;90:6430-6442), and human papillomavirus type 16 infection (associated with cancer of the female genital tract) (Spoden G et al, PLoS One 2008;3:1-15). Other infectious agents associated with CD151 include Neisseria meningitidis, the etiologic agent of meningococcal meningitis (Hauck CR et al, Curr Opin Microbiol 2003;6:43-49 and Green LR et al, Infect Immun 2001;79:2241-2249), and influenza virus (Qiao Y et al, Allergy Clin Immunol 2018;141:1799-1817).

[0009] There is therefore great interest in developing inhibitors of CD151, as compounds with this ability would be expected to be useful in the treatment of these disorders. Summary of the Invention

[0010] Therefore, the applicant has studied the expression of CD151 with the aim of identifying inhibitors of its function that may be applied in the treatment of conditions involving its overexpression.

[0011] As a result of these studies, applicants have identified compounds that inhibit CD151.

[0012] Thus, in one embodiment, the present invention provides a compound of formula (I): [ka] (In the formula, R 1 , R 2 , and R 3 are each independently H and C1 to C 12 is selected from the group consisting of alkyl, R 4 is H and C1 to C 12 is selected from the group consisting of alkyl, R 5 is H, optionally substituted C6-C 18 Aryl, optionally substituted C1-C 18 Heteroaryl, optionally substituted C-C 18 Aryl C1-C 12 Alkyl- and optionally substituted C1-C 18 Heteroaryl C1-C 12 alkyl-, R 6 H, C1~C 12 is selected from the group consisting of alkyl, C3-C6 cycloalkyl, and C1-C5 heterocycloalkyl; R 7 is H and C1 to C 12 is selected from the group consisting of alkyl, R 8 H, C1~C 12 Alkyl, optionally substituted C-C 18 Aryl optionally substituted C1-C 18 Heteroaryl, optionally substituted C-C 18 Aryl C1-C 12Alkyl- and optionally substituted C1-C 18 Heteroaryl C1-C 12 alkyl-, Or R 7 and R 8 When combined with the nitrogen atom to which they are attached, C2 to C 12 forming a heterocyclic group), or a pharmaceutically acceptable salt thereof.

[0013] It has been found that compounds of the present invention have the ability to inhibit CD151 in humans and therefore can be used in the treatment of conditions associated with expression of this gene.

[0014] Additionally, in a still further aspect, the present invention provides a pharmaceutical composition comprising a compound according to formula (I) and a pharmaceutically acceptable diluent, excipient, or carrier. [Brief explanation of the drawings]

[0015] [Figure 1] To measure cell invasion under compound treatment, the upper chamber of the CIM plate was coated with 5% Matrigel diluted in SF RPMI (20 μl) and incubated for 4 hours in a tissue culture incubator at 37°C. An assembly tool was used to support the chamber, and the lower chamber was filled with medium (160 μl) containing specific concentrations of compounds ranging from 25 μM to 1 μM and two controls (DMSO 0.1% and ESFAM 4C 10 μM). DETAILED DESCRIPTION OF THE INVENTION

[0016] In this specification, several terms are used that are well known to those skilled in the art. However, for the sake of clarity, several terms are defined. Throughout the description and claims of this specification, the term "comprise" and variations of terms such as "comprising" and "comprises" are not intended to exclude other additives, components, integers or steps.

[0017] The term "inhibit" and variations thereof, such as "inhibiting," mean to prevent, block, or reduce the function of the entity being inhibited. The term does not require complete inhibition; at least a 50% reduction in activity is considered inhibition.

[0018] In the definitions of some substituents below, it is stated that "the group may be a terminal group or a bridging group." This means that the use of this term is intended to encompass situations where the group is a linker between two other parts of a molecule, as well as situations where the group is a terminal moiety. As an example, using the term alkyl, some publications use the term "alkylene" for a bridging group, and therefore these other publications distinguish between the term "alkyl" (terminal group) and the term "alkylene" (bridging group). In the present application, no such distinction is made, and most groups can be either a bridging group or a terminal group.

[0019] Terms used herein are well known to those skilled in the art, however, for clarity, some of these terms are defined.

[0020] As used herein, the term "unsubstituted" means that there are no substituents or that the substituents are only hydrogen.

[0155] Alternatively, two optional substituents on the same moiety, when taken together, may be linked to form a fused ring substituent attached to the optionally substituted moiety. Thus, the term optionally substituted includes fused rings such as cycloalkyl, heterocycloalkyl, aryl, or heteroaryl rings.

[0156] Specific examples of the compounds of formula (I) of the present invention include: [Table 1-1] [Table 1-2] [Table 1-3] [Table 1-4] [Table 1-5] [Table 1-6] [Table 1-7] [Table 1-8] [Table 1-9] [Table 1-10] [Table 1-11] [Table 1-12] [Table 1-13] [Table 1-14] or a pharmaceutically acceptable salt thereof.

[0157] The compound has the ability to inhibit CD151. The ability to inhibit CD151 may be the result of the compound acting directly and independently on CD151 to regulate / enhance biological activity. However, it is understood that the compound may also at least partially act on other factors related to CD151 activity.

[0158] The inhibition of CD151 can be carried out by any of several methods known in the art.For example, when it is desired to inhibit CD151 in vitro, an appropriate amount of compound can be added to the solution containing CD151.In the situation when it is desired to inhibit CD151 in humans, the inhibition of CD151 typically involves administering a compound to humans containing CD151.

[0159] Thus, the present compounds may find multiple uses that can take advantage of their ability to inhibit CD151 as described above.

[0160] The compounds of the invention are therefore expected to have useful therapeutic properties, particularly with respect to conditions such as cancer. Examples of cancers associated with CD151 activity include prostate cancer, breast cancer, pancreatic cancer, colon cancer, non-small cell lung cancer, hepatocellular carcinoma, intrahepatic cholangiocarcinoma, renal cell carcinoma, endometrial cancer, esophageal cancer, esophageal / gastroesophageal junction cancer, osteosarcoma, Wilms' tumor, mesothelial tumor, squamous cell carcinoma, glioblastoma multiforme, melanoma, and ovarian cancer.

[0161] CD151 activity has also been implicated in diseases such as asthma, multiple sclerosis and inflammatory bowel disease.

[0162] Expression of CD151 is also associated with infection by infectious agents. Inhibition of such CD151 can aid in the treatment of conditions mediated by infectious agents. Examples of this type of infectious agent include human papillomavirus, influenza virus, and meningococcus.

[0163] Administration of compounds within Formula (I) to humans can be via any of the accepted modes of enteral administration, such as oral or rectal, or parenteral administration, such as subcutaneous, intramuscular, intravenous, and intradermal routes. Injection can be via bolus or constant or intermittent infusion. The active compound is typically included in a pharmaceutically acceptable carrier or diluent, and is included in an amount sufficient to deliver a therapeutically effective dose to the patient. In various embodiments, the activator compound can be selectively toxic to, or more toxic to, rapidly proliferating cells, such as cancerous tumors, than normal cells.

[0164] The compounds of the present invention can be administered in any form or manner that makes the compound bioavailable. Those skilled in the art of preparing formulations can easily select an appropriate form and mode of administration depending on the particular characteristics of the compound selected, the condition to be treated, the stage of the condition to be treated, and other relevant circumstances. For further information, see Remington's Pharmaceutical Sciences, 1999. th See the 1995 edition, Mack Publishing Co.

[0165] The compounds of the present invention can be administered alone or in the form of a pharmaceutical composition in combination with a pharmaceutically acceptable carrier, diluent or excipient. Although the compounds of the present invention are effective in themselves, they are typically formulated and administered in the form of their pharmaceutically acceptable salts, as these forms are typically more stable, more easily crystallized and have increased solubility.

[0166] However, compounds are typically used in the form of pharmaceutical compositions formulated according to the desired mode of administration. Thus, in some embodiments, the present invention provides pharmaceutical compositions comprising a compound of formula (I) and a pharmaceutically acceptable carrier, diluent, or excipient. The compositions are prepared by methods well known to those skilled in the art.

[0167] In other embodiments, the present invention provides pharmaceutical packs or kits comprising one or more containers filled with one or more of the ingredients of the pharmaceutical compositions of the present invention. In such packs or kits, containers containing unit dosage amounts of the drug may be found. The kits may contain compositions containing the active agent, which may be provided as a concentrate (including lyophilized compositions) or at a working concentration that can be further diluted before use, and the vials may contain one or more dosage amounts. Conveniently, the kits may provide single dosage amounts in sterile vials, with the vials containing the desired amount and concentration of drug, so that the physician can use the vials directly. Such containers may be associated with various written materials, such as instructions for use or notices in the form prescribed by government agencies regulating the manufacture, use, or sale of pharmaceutical or biological products, which notice reflects the agency's approval of the manufacture, use, or sale for human administration.

[0168] The compounds of the present invention may be used or administered in combination with one or more additional drugs for the treatment of the disorders / diseases mentioned. The components may be administered in the same formulation or in separate formulations. When administered in separate formulations, the compounds of the present invention may be administered sequentially or simultaneously with the other drugs.

[0169] In addition to being able to be administered in combination with one or more additional drugs, the compound of the present invention can be used in combination therapy.When this is done, the compound is typically administered in combination with each other.Therefore, one or more of the compounds of the present invention can be administered simultaneously (as a combined preparation) or sequentially to achieve desired effects.This is particularly desirable when the therapeutic profile of each compound is different, and therefore the combined effect of the two drugs provides improved therapeutic results.

[0170] The pharmaceutical compositions of the present invention for parenteral injection include pharmaceutically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions, or emulsions, and sterile powders, which are to be reconstituted immediately before use into sterile injectable solutions or dispersions. Examples of suitable aqueous and non-aqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (glycerol, propylene glycol, polyethylene glycol, etc.), and suitable mixtures thereof, vegetable oils (olive oil, etc.), and injectable organic esters such as ethyl oleate. The appropriate fluidity can be maintained, for example, by using coating materials such as lecithin, by maintaining the required particle size in the case of dispersions, and by using surfactants.

[0171] These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents, and dispersing agents. Prevention of microbial action can be ensured by including various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol sorbic acid, etc. It may also be desirable to include isotonic agents such as sugars, sodium chloride, etc. Prolonged absorption of injectable pharmaceutical forms can be brought about by including agents that delay absorption, such as aluminum monostearate and gelatin.

[0172] If desired, and for more effective distribution, the compounds can be incorporated into slow-release or targeted-delivery systems such as polymer matrices, liposomes, and microspheres.

[0173] Injectable preparations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium immediately before use.

[0174] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate, and / or a) fillers or enhancers such as starches, lactose, sucrose, glucose, mannitol, and silicic acid; b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia; c) humectants such as glycerol; d) agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; e) solution retarders such as paraffin; f) absorption accelerators such as quaternary ammonium compounds; g) humectants such as, for example, cetyl alcohol and glycerol monostearate; h) adsorbents such as kaolin and bentonite clay; and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

[0175] Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar, as well as high molecular weight polyethylene glycols and the like.

[0176] Solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.

[0177] The active compounds can also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients.

[0178] The liquid dosage form for oral administration includes pharmaceutically acceptable emulsion, solution, suspension, syrup and elixir.In addition to active compound, liquid dosage form can contain the inert diluent commonly used in the art, such as water or other solvent, solubilizer and emulsifier, for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oil (especially cottonseed, peanut, corn, germ, olive, castor and sesame oil), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycol and fatty acid ester of sorbitan and their mixtures.

[0179] Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

[0180] Suspensions may contain, in addition to the active compound, suspending agents such as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures thereof.

[0181] Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing a compound of the present invention with a suitable non-irritating excipient or carrier such as cocoa butter, polyethylene glycol or a suppository wax which is solid at room temperature but liquid at body temperature and therefore melts in the rectum or vaginal cavity to release the active compound.

[0182] Dosage forms for topical administration of a compound of this invention include powders, patches, sprays, ointments, and inhalants. The active compound is admixed under sterile conditions with a pharmaceutically acceptable carrier, and any needed preservatives, buffers, or propellants which may be required.

[0183] The amount of compound administered preferably treats, reduces or alleviates the condition. The therapeutically effective amount can be easily determined by a diagnostician using conventional techniques and by observing the results obtained under similar circumstances. When determining the therapeutically effective amount, several factors should be taken into consideration, including but not limited to the species of animal, its size, age and general health, the specific condition involved, the severity of the condition, the patient's response to treatment, the specific compound administered, the mode of administration, the bioavailability of the administered preparation, the selected dosage regime, the use of other medications, and other relevant circumstances.

[0184] A preferred dosage ranges from about 0.01 to 300 mg per kilogram of body weight per day. A more preferred dosage ranges from 0.1 to 100 mg per kilogram of body weight per day, more preferably from 0.2 to 80 mg per kilogram of body weight per day, and even more preferably from 0.2 to 50 mg per kilogram of body weight per day. A suitable dose may be administered in multiple subdoses per day.

[0185] Synthesis of Compounds of the Invention The compounds for use in the methods of the present invention can be prepared using known organic synthesis techniques and can be synthesized using readily available starting materials and techniques available in the art according to any of a number of possible synthetic routes, including the reaction routes and synthetic schemes described below. The preparation of the compounds of the embodiments is described in detail in the examples below, but one of ordinary skill in the art will recognize that the chemical reactions described can be readily adapted to prepare other agents of various embodiments.

[0186] The reaction for preparing the compounds of the present invention can be carried out in a suitable solvent, which can be easily selected by those skilled in the art of organic synthesis. A suitable solvent can be substantially non-reactive with the starting materials (reactants), intermediates, or products at the temperature at which the reaction is carried out, which can range from the freezing temperature of the solvent to the boiling temperature of the solvent. A given reaction can be carried out in one solvent or in a mixture of two or more solvents. Depending on the reaction step, a suitable solvent for a particular reaction step can be selected by those skilled in the art.

[0187] The preparation of compounds of the present invention can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups can be found, for example, in T.W. Greene and P.G.M. Buts, Protective Groups in Organic Synthesis, 3rd Ed., Wiley & Sons, Inc., New York (1999), which is incorporated herein by reference in its entirety.

[0188] Reactions can be monitored according to any suitable method known in the art, for example, product formation can be monitored by spectroscopic means such as nuclear magnetic resonance spectroscopy (e.g., H or C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), or mass spectrometry, or by chromatography, such as high performance liquid chromatography (HPLC) or thin layer chromatography.

[0189] As used herein, the expressions "ambient temperature," "room temperature," and "rt" are understood in the art and generally refer to a temperature, such as a reaction temperature, which is about the temperature of the room in which the reaction is carried out, e.g., a temperature of about 20° C. to about 30° C.

[0190] The present invention will now be described by way of example, which should not be construed as a limitation on the invention. Additional compounds, other than those described below, can be prepared using the methods and synthetic protocols described herein, or suitable variations or modifications thereof. [Example]

[0205] Thin layer chromatography (TLC) was used to monitor reactions and chromatographic fractions on Merck Kieselgel 60 F254 aluminum-backed plates. Silica gel 60 F254 was used as the stationary phase for flash chromatography. Unless otherwise stated, gradient elution with ethyl acetate (EtOAc) and hexane was used for analytical grade.

[0206] All glassware used in reactions requiring anhydrous conditions was oven dried (120°C) and then cooled under nitrogen before use.

[0207] General schemes for the formation of some compounds of the invention are shown below in Schemes 1 and 2, which can be modified as necessary to make some compounds of the invention. As shown in Scheme 1, the typical first step is to synthesize the heteroaromatic core molecule (in situations where this is not readily available).

[0208] In general, a suitably protected diacid moiety (I) is reacted with a suitably functionalized acetylene in the presence of a strong base to form II. Compound II is then reacted with hydrazine to form a five-membered heterocyclic compound (III). Compound III is then reacted with a suitably substituted diacid to form amide IV, which is then cyclized to form bicyclic heteroaromatic compound V. Finally, to further elaborate the ring substituents, compound V is reacted with POCl to insert a chloro group (compound VI). This scheme illustrates one form of formation of an advanced intermediate for the synthesis of compounds of the present invention, as will be understood by those skilled in the art. Variation of the R group on the acetylene and the ester group on the starting diacid allows for the creation of a large number of different advanced intermediates using this technique. [ka]

[0209] Once advanced intermediate VI has been prepared using the procedures shown in Scheme 1, it can be elaborated into compounds of the invention using the procedures of Scheme 2, as shown below. Typically, a compound of formula VI is subjected to Suzuki coupling with a suitable heteroaromatic boronic acid to introduce the heteroaromatic group and form a compound of formula VII. Reaction of compound VII with a suitably substituted diamine provides a compound of formula VIII, which is then saponified to remove the acid protecting group and generate the free acid IX. This is then subjected to amide coupling with a suitable aromatic amine to form a compound of formula X. [ka]

[0210] As will be appreciated by those skilled in the art, the procedures outlined in Schemes 1 and 2 can be modified using methods well known in the art to arrive at any number of compounds of the present invention. Additionally, in the Examples below, modifications of the reactions shown in these Schemes are provided as examples of how this can be done.

[0401] Example 128 Biological Activity. 1.1 Cell culture Culture medium, antibiotics, and serum were purchased from Invitrogen (Life Technologies). PC3 cells were purchased from ATCC (Granville, NSW, Australia). PC3 cells were grown in cell culture T75 flasks with vented caps and then stored at low passage numbers. The medium used for PC3 cells was RPMI (GlutaMAX) supplemented with 10% FCS and 1% penicillin / streptomycin (culture medium). Cells were maintained at 37°C in a humidified 95% (v / v) air / 5% (v / v) CO2 atmosphere and grown to 80% confluence.

[0402] 1.2 x CELLigence Plates XCELLigence® Real-Time Cell Analysis (RTCA) instrument (ACEA Biosciences), 16-well ACEA CIM-plates, 16-well ACEA E-plates, and assembly tools were purchased from ELITech Group empowering IVD (Braeside, Australia). Matrigel was purchased from Corning (Australia).

[0403] 1.2.1 Cell seeding on CIM plates and cell invasion and proliferation on xCELLigence RTCA DP To measure cell invasion under compound treatment, the upper chamber of the CIM plate was coated with 5% Matrigel diluted in SF RPMI (20 μl) and incubated for 4 hours in a tissue culture incubator at 37 °C. Using an assembly tool to support the chamber, the lower chamber was filled with medium (160 μl) containing specific concentrations of compound (25 μM–1 μM) and two controls (DMSO 0.1% and ESFAM 4C 10 μM) (see schematic diagram in Figure 1). Once the upper chamber was placed on top of the lower chamber, compound-containing serum-free (SF) RPMI (40 μl) was added, as described above. After 1 hour of calibration at 37 °C, the plate was placed in the xCELLigence station, and baseline electrical impedance was measured to confirm that all wells and connections were functioning properly. If a connection problem occurred, the software automatically notified the researcher of the nature of the problem in the message section. The cells were then trypsinized, harvested, and counted, followed by dilution in SF RPMI to the desired density (3 × 10). 4 ) and seeded into the wells (100 μl). After a 30-minute incubation at room temperature to allow cell attachment, the plate was placed in the xCELLigence RTCA DP instrument. Cell invasion was monitored in real time for 72 hours.

[0404] It is important to note that the same procedure was followed with minor modifications to measure cell proliferation under compound treatment, but cell proliferation was monitored in real time using the E-Plate and xCELLigence station (see Figure 1).

[0405] 1.3 Software and Data Analysis The xCELLigence system automatically monitored the electrical impedance values ​​of each well and expressed them as Cell Index (CI) values ​​at 72 hours. Data for treatments were automatically grouped as mean ± standard deviation. The software version used in these experiments was 1.2.1. Electronic records of experimental data were automatically saved in files that researchers could not alter or modify.

[0406] Statistical analysis was performed using Microsoft® Office EXCEL and GraphPad Prism 7. IC50s were calculated from four-parameter dose-response curves (log(inhibitor) vs. response-variable slope). Raw data were inserted into GraphPad Prism 7 (dose-response x-log(dose)) and analyzed for XY nonlinear regression (curve fitting), dose-response-inhibition, log(inhibitor) vs. response-variable slope (four parameters). For IC90 calculations, the formula log(IC50) = log(IC90) - (1 / HillSlope) * log(9) was used in EXCEL based on the raw data and dose-response curves extracted from the xCELLigence system.
