[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Patent Application No. 62 / 805,854, filed February 14, 2019, the entire contents of which are incorporated herein by reference.

[0002] Incorporating sequence tables The contents of the attached sequence listing are incorporated by reference into this application. The attached sequence listing text file is named BRIDGE1100_1WO_Sequence_Listing.txt, was created on February 13, 2020, and is 1084kb. The file can be accessed using Microsoft Word on a computer using the Windows OS.

[0003] Field The present disclosure relates generally to novel fibroblast growth factor receptor (FGFR) inhibitors, and more specifically to the use of pyridinylpyrimidine-based FGFR4-specific inhibitors for the treatment of cancer. [Background technology]

[0004] background The human fibroblast growth factor receptor (FGFR) family is composed of four receptor tyrosine kinases that bind to 18 ligands called fibroblast growth factors (FGFs). The four members (FGFR1, FGFR2, FGFR3, and FGFR4) are highly conserved with each other and consist of an extracellular ligand-binding domain, a transmembrane segment, and a cytoplasmic tyrosine kinase domain. Upon ligand binding to the extracellular domain of FGFR, the kinase domain is activated by autophosphorylation, which then phosphorylates the cytoplasmic substrate, triggering downstream signaling cascades that control cell proliferation and differentiation.

[0005] The FGFR signaling pathway is an important and plausible target for cancer therapeutics because it plays a key role in tumor proliferation, angiogenesis, migration, and survival. Mutations and overexpression of FGFRs and their ligands have been reported in several cancers, including breast, lung, bladder, prostate, and gastric cancers. For example, FGFR1 amplifications have been found in approximately 10% of breast cancers (mainly estrogen receptor-positive disease), 10–20% of squamous non-small cell lung cancers (NSCLC), ovarian cancers (approximately 5%), and bladder cancers (3%). FGFR2 amplifications have been detected in gastric cancers (5–10%) and breast cancers (4% of triple-negative cases), and FGFR2 mutations occur in 12% of endometrial cancers. FGFR3 mutations have been identified in approximately 70% of non-muscle invasive bladder cancers and 10–20% of invasive high-grade bladder cancers. Amplification and activating mutations of FGFR4 have been described in 8% of rhabdomyosarcoma patients. Furthermore, numerous preclinical studies have reported overexpression of FGFR4 in prostate, colon, and liver cancers.

[0006] Many FGFR small molecule inhibitors have been developed and evaluated in clinical trials for cancer treatment, most of which are pan-FGFR inhibitors with promiscuous kinome activity, such as BGJ398 and LY-2874455. Sequence analysis has found that FGFR4 contains a cysteine ​​(Cys552) located near the ATP-binding site in the hinge region of the receptor, which is unique within the FGFR family and rare among other kinases. Indeed, BLU9931, a first-line FGFR4 inhibitor, was recently discovered to target this unique cysteine ​​and showed very good specificity and significant antitumor activity against hepatocellular carcinoma in vivo. However, the potency and bioavailability of BLU9931 are not optimal for clinical use. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] explanation Disclosed herein is a class of compounds that are selective inhibitors of FGFR4. These small molecule inhibitors can be used as targeted therapeutics to treat cancer.

[0028] Fibroblast growth factor receptors (FGFRs) are highly conserved receptors consisting of an extracellular ligand-binding domain, a transmembrane segment, and a cytoplasmic tyrosine kinase domain. The human FRFR family includes four members, FGFR1, FGFR2, FGFR3, and FGFR4, which can be bound by 18 different ligands called fibroblast growth factors (FGFs). Each receptor is composed of an extracellular domain consisting of three immunoglobulin-like domains (IgI, IgII, and IgIII) and an acid box, an IgII and IgIII domain that constitute the FGF ligand-binding site, a transmembrane domain, and a tyrosine kinase cytoplasmic domain. FGFRs also contain a hinge region (subdomain V) located near the ATP-binding site (SEQ ID NO:57-60). The FGFR encoding mRNA is subject to alternative splicing resulting in several protein-coding splice variants or isoforms (SEQ ID NOs: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, and 55). As shown in Table 3, the human FGFR1 gene encodes nine protein-coding splice variants (SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, and 18), the human FGFR2 gene encodes eleven protein-coding splice variants (SEQ ID NOs: 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, and 40), the human FGFR3 gene encodes four protein-coding splice variants (SEQ ID NOs: 42, 44, 46, and 48), and the human FGFR4 gene encodes four protein-coding splice variants (SEQ ID NOs: 50, 52, 54, and 56).

[0029] The FGF family of ligands has 18 members (FGF1-FGF10 and FGF16-FGF23). Ligand binding to the extracellular domain of FGFR leads to receptor dimerization, which results in activation of the tyrosine kinase domain by autophosphorylation. Activated FGFR subsequently phosphorylates cytoplasmic substrates, such as FGFR substrate 2 (FRS2) and phospholipase Cγ (PLCγ), which triggers downstream signaling cascades. Activated FRS2 promotes the RAS-mitogen-activated protein kinase (MAPK) or phosphoinositide 3-kinase (PI3K)-AKT pathways that regulate cell proliferation, differentiation, and survival. Meanwhile, activation of PLCγ leads to calcium release, regulating events that mediate cell motility.

[0030] Deregulation of FGFR signaling has been linked to carcinogenesis through several mechanisms, including activating mutations, gene amplification or altered post-transcriptional processing, and translocations, resulting in constitutive activation of the receptor.

[0031] Specifically, amplification and activating mutations of FGFR4 have been described in patients with rhabdomyosarcoma, and FGFR4 overexpression has been associated with prostate, colon, breast, and liver cancer. FGFR4 differs from other FGFRs by the presence of a cysteine ​​in the hinge region, which is unique within the FGFR family and rare among other kinases. Depending on the isoform, the cysteine ​​is located at different positions: Cys484 of SEQ ID NO:52, Cys512 of SEQ ID NO:56, or Cys552 of SEQ ID NO:50 or 54. This unique cysteine ​​can be targeted to design FGFR4-specific inhibitors that show very good specificity.

[0032] As used herein, the term "FGFR inhibitor" or "FGFRi" refers to any compound capable of inhibiting the enzymatic activity of FGFR, including the autophosphorylation and kinase activity of FGFR itself. Such inhibitors are said to effectively inhibit FGFR and "inhibit," "reduce," or "diminish" the biological activity of FGFR. The FGFR inhibitors of the present disclosure may be "pan-inhibitors" and may exhibit broad efficacy in inhibiting one or more of GFR1-FGFR4, or may exhibit specific efficacy in inhibiting only one FGFR, e.g., FGFR4.

[0033] The efficiency of a compound can be referred to by its IC50 value. "IC50" is the half-maximal inhibitory concentration (IC50) of a compound. As used herein, the IC50 of an FGFRi refers to the concentration of an inhibitor sufficient to induce inhibition of the enzyme activity of FGFR halfway between baseline and maximum after a specified exposure time. The IC50 value of the present disclosure specifically refers to the concentration of an FGFR inhibitor sufficient to induce inhibition of one or more FGFRs, namely FGFR1, FGFR2, FGFR3 and / or FGFR4.

[0079] As used herein, the term "therapeutically effective amount" refers to an amount of an active compound or agent that elicits a biological or medical response in a tissue, system, animal, individual, or human that is desired by a researcher, veterinarian, physician, or other clinician, the response including one or more of the following: (1) preventing a disease, e.g., preventing a disease, condition, or disorder in an individual who may be predisposed to the disease, condition, or disorder but has not yet experienced or exhibited the pathology or symptoms of the disease; (2) inhibiting a disease, e.g., inhibiting a disease, condition, or disorder in an individual who is experiencing or exhibiting the pathology or symptoms of the disease, condition, or disorder (i.e., arresting further development of the pathology and / or symptoms); and (3) ameliorating a disease, e.g., ameliorating a disease, condition, or disorder in an individual who is experiencing or exhibiting the pathology or symptoms of the disease, condition, or disorder (i.e., reversing the pathology and / or symptoms).

[0080] The compounds of the present disclosure may be used in conventional methods for controlling diseases described herein, including but not limited to cancer.Such treatment methods, their dosage levels and requirements may be selected by those skilled in the art from available methods and techniques.For example, the compounds of the present disclosure may be combined with pharmaceutically acceptable adjuvants for administration to patients suffering from cancer in a pharmaceutically acceptable manner and in an amount effective for treating cancer.

[0081] Alternatively, the compounds of the present disclosure may be used in compositions and methods for treating or protecting individuals against diseases described herein, including but not limited to cancer, over a long period of time.The compounds may be used in such compositions alone or together with other compounds of the present disclosure in a manner consistent with the conventional use of such compounds in pharmaceutical compositions.For example, the compounds of the present disclosure may be combined with pharma- ceutically acceptable adjuvants that are conventionally used in vaccines and are administered in prophylactically effective amounts to protect individuals against diseases described herein, including but not limited to cancer, over a long period of time.

[0082] As used herein, "combination," "combined," and related terms refer to simultaneous or sequential administration of therapeutic agents according to the present disclosure. For example, the described compound may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms, or together in a single unit dosage form. Thus, the present disclosure provides a single unit dosage form that includes the described compound, an additional therapeutic agent, and a pharma- ceutically acceptable carrier, adjuvant, or vehicle. Two or more agents are typically considered to be administered "in combination" when a patient or individual is exposed to both agents simultaneously. In many embodiments, two or more agents are considered to be administered "in combination" when a patient or individual simultaneously exhibits therapeutically relevant drug levels in a particular target tissue or sample (e.g., in the brain, in serum, etc.).

[0083] When the compounds of the present disclosure are administered in combination therapy with other agents, they may be administered sequentially or simultaneously to a patient. Alternatively, a pharmaceutical or prophylactic composition according to the present disclosure includes a combination of ivermectin or any other compound described herein with another therapeutic or prophylactic agent. Additional therapeutic agents that are normally administered to treat a particular disease or condition may be referred to as "agents appropriate for the disease or condition being treated."

[0084] The compounds utilized in the compositions and methods of the present disclosure may be modified by adding appropriate functional groups to enhance selective biological properties. Such modifications are known in the art and include modifications that increase biological penetration into a given biological system (e.g., blood, lymphatic system, or central nervous system), increase oral availability, increase solubility to allow administration by injection, alter metabolism, and / or alter excretion rate.

[0085] According to a preferred embodiment, the compositions of the present disclosure are formulated for pharmaceutical administration to a subject or patient, such as a mammal, preferably a human. Such pharmaceutical compositions are used to ameliorate, treat, or prevent any of the diseases described herein, including but not limited to cancer, in a subject.

[0086] The agents of the present disclosure are often administered as pharmaceutical compositions containing an active therapeutic agent, i.e., and various other pharma- ceutical acceptable components. See Remington's Pharmaceutical Science (15th ed., Mack Publishing Company, Easton, Pa., 1980). The preferred form depends on the intended mode of administration and therapeutic application. The composition may also contain a pharma- ceutical acceptable non-toxic carrier or diluent, defined as a vehicle commonly used to formulate pharmaceutical compositions for animal or human administration, depending on the desired formulation. The diluent is selected so as not to affect the biological activity of the combination. Examples of such diluents are distilled water, phosphate-buffered saline, Ringer's solution, dextrose solution, and Hank's solution. In addition, the pharmaceutical composition or formulation may also contain other carriers, adjuvants, or non-toxic, non-therapeutic, non-immunogenic stabilizers, and the like.

[0087] In some embodiments, the present disclosure provides pharma- ceutically acceptable compositions comprising a therapeutically effective amount of one or more of the described compounds, formulated with one or more pharma- ceutically acceptable carriers (additives) and / or diluents, for use in the treatment of diseases described herein, including but not limited to cancer. Although it is possible to administer the described compounds alone, it is preferred to administer the described compounds as pharmaceutical formulations (compositions) as described herein. The described compounds, like other pharmaceuticals, may be formulated for administration in any convenient manner for use in human or veterinary medicine.

[0088] As described in detail, the pharmaceutical compositions of the present disclosure may be specifically formulated for administration in solid or liquid form, including, for example, those adapted for oral administration, e.g., drenches (aqueous or non-aqueous solutions or suspensions), tablets, e.g., buccal, sublingual, and tablets targeted for systemic absorption, boluses, powders, granules, pastes for application to the tongue; parenteral administration, e.g., subcutaneous, intramuscular, intravenous, or epidural injection, e.g., sterile solutions or suspensions, or sustained release formulations; topical application, e.g., as creams, ointments, or controlled release patches applied to the skin, lungs, or buccal cavity, or as sprays; vaginal, rectal, e.g., as pessaries, creams, or foams; sublingual; ocular; transdermal; or nasal, pulmonary, and other mucosal surfaces.

[0089] Wetting agents, emulsifying agents, and lubricating agents, such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, release agents, coating agents, sweetening, flavoring, and perfuming agents, preservatives, and antioxidants can also be present in the composition.

[0090] Examples of pharma- ceutically acceptable antioxidants include water-soluble antioxidants, such as ascorbic acid, cysteine ​​hydrochloride, sodium bisulfate, sodium metabisulfite, sodium sulfite, and the like; oil-soluble antioxidants, such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, α-tocopherol, and the like; and metal chelators, such as citric acid, ethylenediaminetetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the like.

[0091] Formulations for use according to the present disclosure include those suitable for oral, nasal, topical (including buccal and sublingual), rectal, vaginal, and / or parenteral administration. The formulations may be conveniently presented in unit dosage form and may be prepared by any method well known in the art of pharmacy. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will vary depending on the host treated and the particular mode of administration. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound that produces a therapeutic effect. Generally, this amount will range from about 1% to about 99% of the active ingredient. In some embodiments, this amount will range from about 5% to about 70%, about 10% to about 50%, or about 20% to about 40%.

[0092] In certain embodiments, the formulations described herein comprise an excipient selected from the group consisting of cyclodextrins, liposomes, micelle forming agents, such as bile acids, and polymeric carriers, such as polyesters and polyanhydrides, and a compound of the present disclosure. In certain embodiments, the formulations described herein render the compounds of the present disclosure orally bioavailable.

[0093] The method for preparing the formulation or composition containing the described compound comprises combining the compound of the present disclosure with carrier and optionally one or more accessory ingredients.Generally, the formulation can be prepared by uniformly and intimately combining the compound of the present disclosure with liquid carrier or finely divided solid carrier or both, and then shaping the product as necessary.

[0094] The pharmaceutical composition may be in the form of a sterile injectable preparation, for example, a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to techniques known in the art using suitable dispersing or wetting agents (such as, for example, Tween 80) and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be used are mannitol, water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile fixed oils are conventionally used as a solvent or suspending medium. For this purpose, any bland fixed oil may be used, including synthetic mono- or diglycerides. Fatty acids such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharma- ceutical acceptable oils such as olive oil or castor oil, especially in their polyoxyethylated forms. These oil solutions or suspensions may also contain long-chain alcohol diluents or dispersants, such as those described in the Pharmacopeia Helvetica, or similar alcohols. Other commonly used surfactants, such as Tweens, Spans, and other emulsifiers or bioavailability enhancers commonly used in the manufacture of pharma- ceutically acceptable solid, liquid, or other dosage forms, may also be used for formulation purposes.

[0095] In some cases, it may be desirable to delay the absorption of drugs from subcutaneous or intramuscular injection in order to prolong the effect of drugs.This can be achieved by using liquid suspensions of crystalline or amorphous materials with poor water solubility.The absorption rate of the drug then depends on its dissolution rate, which in turn depends on the crystal size and crystalline form.Alternatively, delayed absorption of parenterally administered drug forms can be achieved by dissolving or suspending the drug in an oil vehicle.

[0096] Injectable depot forms are prepared by forming microencapsule matrices of the described compounds in biodegradable polymers such as polylactide-polyglycolide.Depending on the ratio of drug to polymer and the nature of the particular polymer used, the drug release rate can be controlled.Other examples of biodegradable polymers include poly(orthoesters) and poly(anhydrides).Depot injectable formulations are also prepared by encapsulating the drug in liposomes or microemulsions that are compatible with body tissues.

[0097] The pharmaceutical composition of the present disclosure may be orally administered in any orally acceptable dosage form, including but not limited to capsules, tablets, and aqueous suspensions and solutions.For oral tablets, commonly used carriers include lactose and corn starch.Lubricants such as magnesium stearate are also typically added.For oral administration in capsule form, useful diluents include lactose and dried corn starch.For oral administration of aqueous suspensions, solutions, and propylene glycol, the active ingredient is combined with emulsifying and suspending agents.If desired, certain sweeteners and / or flavors and / or colorants may be added.

[0098] Formulations described herein suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored base, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia), and / or as mouthwash, each containing a predetermined amount of a compound of the present disclosure as an active ingredient. Compounds described herein may also be administered as a bolus, electuary, or paste.

[0099] In solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules, etc.), the active ingredient is mixed with one or more pharma- ceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and / or any of the following: fillers or extenders, such as starch, lactose, sucrose, glucose, mannitol, and / or silicic acid; binders, such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and / or acacia; wetting agents, such as glycerol; Disintegrants such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; solution retarders such as paraffin; absorption accelerators such as quaternary ammonium compounds; wetting agents such as cetyl alcohol, glycerol monostearate, and nonionic surfactants; absorbents such as kaolin and bentonite clay; lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof, and coloring agents. In the case of capsules, tablets, and pills, the pharmaceutical composition may also contain buffering agents. Solid compositions of a similar type may also be used as fillers in soft and hard shell gelatin capsules, using excipients such as lactose or milk sugar, and high molecular weight polyethylene glycols.

[0100] Tablets may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binders (e.g., gelatin or hydroxypropylmethylcellulose), lubricants, inert diluents, preservatives, disintegrants (e.g., sodium starch glycolate or cross-linked sodium carboxymethylcellulose), surface active agents, or dispersants. Molded tablets may be made in a suitable machine in which a mixture of powdered compounds is moistened with an inert liquid diluent. When a solid carrier is used, the preparation may be in tablet form, placed in a hard gelatin capsule in powder or pellet form, or in the form of a troche or lozenge. The amount of solid carrier varies, for example, from about 25 to 800 mg, preferably from about 25 mg to 400 mg. When a liquid carrier is used, the preparation may be in the form of a sterile injectable liquid, such as, for example, a syrup, emulsion, soft gelatin capsule, ampoule, or non-aqueous liquid suspension. Where the composition is in the form of a capsule, any routine encapsulation is suitable, for example using the above carriers in a hard gelatin capsule shell.

[0101] Tablets and other solid dosage forms, such as dragees, capsules, pills, and granules, may be obtained or prepared with optional coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical formulation art. Alternatively or additionally, they may be formulated to provide delayed or controlled release of the active ingredient therein, for example, using various proportions of hydroxypropylmethylcellulose, other polymer matrices, liposomes, and / or microspheres to provide the desired release profile. They may be formulated for rapid release, such as lyophilization. They may be sterilized, for example, by filtration through a bacteria-retaining filter, or by incorporating a sterilizing agent in the form of a sterile solid composition that can be dissolved in sterile water or some other sterile injectable medium immediately before use. These compositions may also optionally contain opacifying agents, and may be compositions that release the active ingredient only, or preferentially, in a certain part of the gastrointestinal tract, optionally in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. The active ingredient may also be in microencapsulated form, where appropriate, with one or more of the above-mentioned excipients.

[0102] The liquid dosage form for oral administration of the compound of the present disclosure includes pharmaceutically acceptable emulsion, microemulsion, solution, suspension, syrup and elixir.In addition to active ingredient, liquid dosage form may contain inert diluent commonly used in the art, such as water or other solvent, solubilizer and emulsifier, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oil (especially cottonseed oil, peanut oil, corn oil, germ oil, olive oil, castor oil and sesame oil), glycerol, tetrahydrofuryl alcohol, polyethylene glycol and fatty acid ester of sorbitan, and mixtures thereof.

[0103] Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming, and preservative agents.

[0104] 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.

[0105] The pharmaceutical composition of the present disclosure may also be administered in the form of suppositories for rectal administration.These compositions can be prepared by mixing the compound of the present disclosure with suitable non-irritating excipients, which are solid at room temperature but liquid at rectal temperature, and therefore melt in rectum to release active ingredient.Such materials include but are not limited to cocoa butter, beeswax, and polyethylene glycol.

[0106] Topical administration of the pharmaceutical composition of the present disclosure is particularly useful when the desired treatment involves areas or organs easily accessible by topical application. For topical application to the skin, the pharmaceutical composition should be formulated with a suitable ointment containing the active ingredient suspended or dissolved in a carrier. Carriers for topical administration of the compounds of the present disclosure include, but are not limited to, mineral oil, liquid petroleum, white petrolatum, propylene glycol, polyoxyethylene polyoxypropylene compounds, emulsifying wax, and water. Alternatively, the pharmaceutical composition can be formulated with a suitable lotion or cream containing the active compound suspended or dissolved in a carrier. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol, and water. The pharmaceutical composition of the present disclosure may also be applied topically to the lower intestinal tract by rectal suppository formulation or in a suitable enema formulation.

[0125] In further embodiments, the disclosure provides a method of inhibiting kinase activity comprising contacting a cell with a compound of formula (I), formula (II), or formula (III). In one aspect, the kinase is selected from the group consisting of ALK, EGFR, EPH-B3, FAK, FGFR1, FGFR2, FGFR3, FGFR4, KIT, MEK1, MET, PDGFR-ALPHA, PDGFR-BETA, RET, ROS, and TYRO3. In a particular aspect, the kinase is FGFR1, FGFR2, FGFR3, and / or FGFR4. In another aspect, the kinase is FGFR4. In various aspects, the cell is a cancer cell. In many aspects, the cancer cell is a breast cancer, lung cancer, bladder cancer, prostate cancer, ovarian cancer, endometrial cancer, rhabdomyosarcoma, liver cancer, or gastric cancer cell.

[0126] Referring to Figure 1, FGFR4 kinase contains a cysteine ​​(Cys552) located near the ATP binding site in the hinge region of the receptor, which is unique within the FGFR family and rare among other kinases. Covalent inhibitors of FGFR4 kinase provide potent and selective inhibition of FGFR by covalently targeting the thiol group (SH) in the cysteine ​​residue.

[0127] The screening method used in the present disclosure according to some embodiments is described as follows: Screening probes for live cells or living animals can include the steps of (1) treating live cells with electrophilic probes to generate covalent bonds between target proteins and probes, (2) lysing cells, (3) adding biotin-azide to conjugate biotin to probe-modified proteins by copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction, (4) using streptavidin resin to pull down and enrich biotin-bound proteins, (5) digesting resin-bound proteins with trypsin, (6) analyzing the resulting tryptic peptides by liquid chromatography-mass spectrometry (LC-MS) or MS, and (7) obtaining information on the identity of the target protein and the strength of the probe-target interaction in cells. Target validation and selection can include (1) using orthogonal methods, such as Western blot, to confirm that the identified proteins actually bind to the probes, and (2) selecting the most disease-relevant target-lead pairs for further preclinical and clinical studies.
