[0002] MET is a member of the class IV receptor tyrosine kinase family and is expressed on the surface of many different cell types, including epithelial cells of many organs, including the liver, pancreas, prostate, kidney, muscle, and bone marrow, during both embryonic development and adulthood. Binding to hepatocyte growth factor induces receptor dimerization and activation. MET modulates many essential cellular processes during development and wound healing, including cell proliferation, survival, motility, and morphogenesis.

[0019] The terms "resistance to therapy" or "acquired resistance to therapy" indicate that a patient has progressive disease due to clinical or molecular resistance to therapy after initially responding to previous therapy. Acquired resistance can result from the emergence of resistance mutations in the molecular target of the therapy or in the development of physiological functions such as efflux pumps.

[0020] As used herein, the phrase "therapeutically effective amount" refers to the amount of a drug or pharmaceutical agent that elicits a biological or medical response in a tissue, system, animal or human that is sought by a researcher, veterinarian, physician or other.

[0021] Other aspects, advantages, and features of the present invention will become apparent from the following detailed description.

[0022] MET tyrosine kinase The MET protein is a member of the class IV receptor tyrosine kinase family and is expressed on the surface of many different cell types, including epithelial cells of many organs such as the liver, pancreas, prostate, kidney, muscle and bone marrow, both during embryonic development and in adulthood. MET regulates many essential cellular processes during development and wound healing, including cell proliferation, survival, motility, and morphogenesis. Aberrant MET activity is found in many different human cancers, such as non-small cell lung cancer, medulloblastoma, lymphoma, melanoma, glioma, breast cancer, pancreatic cancer, colorectal cancer, ovarian cancer and prostate cancer, as well as osteosarcoma and some soft tissue sarcomas.

[0023] The c-MET proto-oncogene is located on chromosome 7q21-31 and its transcription is regulated by Ets (E-twenty six), Pax3 (paired box 3), AP2 (activator protein-2) and Tcf-4 (transcription factor 4). It is represented as multiple mRNA transcripts of 8, 7, 4.5, 3 and 1.5 kilobases. The protein product of this gene is the MET receptor tyrosine kinase.

[0024] Structurally, MET is a single-pass transmembrane protein with an extracellular domain, a transmembrane hydrophobic sequence, and an intracellular portion containing a tyrosine kinase domain. The extracellular domain of MET consists of three domain types: a semaphorin (Serna) domain, a PSI domain, and four immunoglobulin-plexin-transcription (IPT) domains. The N-terminal 500 residues fold to form a large Serna domain, which shares sequence homology with domains found in the semaphorin and plexin families. The PSI domain (found in plexins, semaphorins, and integrins) follows the Serna domain, connecting the Serna domain to the IPT domain over approximately 50 residues. The four IPT domains are associated with immunoglobulin-like domains and are found in integrins, plexins, and transcription factors. The c-terminal IPT domains are then connected to a single transmembrane helix that connects the extracellular domain to the intracellular domain. The intracellular domain of the MET receptor includes a perimembrane domain containing the Y1003 residue, which is involved in receptor downregulation; the tyrosine kinase catalytic domain contains the Y1234 and Y1235 residues, which are involved in signal transduction; and the docking site of the adapter protein contains the Y1349 and Y1356 residues.

[0025] The extracellular portion of MET binds to its homologous ligand, hepatocyte growth factor (HGF), and its native isoform, NK1, resulting in dimerization of the two MET proteins. This dimerization leads to trans-autophosphorylation of two tyrosine residues (Y1234 and Y1235) located within the catalytic loop of the intracellular tyrosine kinase domain. Subsequently, tyrosine residues 1349 and 1356 in the carboxy-terminal tail are phosphorylated, thereby forming a unique tandem SH2 recognition motif and leading to the recruitment of signal effector proteins involved in downstream signal transduction (e.g., GABI, GRB2, SHC, CRK, PI3K, PLCγ1, SHP2, and STAT3).

[0026] HGF, the primary ligand for MET, is a secreted single-chain 83kDa precursor protein. Full-length HGF contains an N-terminal (N) domain, four consecutive kringle (K1-K4) domains, and a serine protease homology (SPH) domain. Proteolytic cleavage between Arg494 and Val495 of HGF produces a 57kDa α-subunit and a 26kDa β-subunit, which are covalently linked by a disulfide bond between Cys487 of the α-subunit and Cys604 of the β-subunit. Both pro-HGF and cleaved HGF can bind to MET with high affinity, but only cleaved mature HGF can activate MET signaling. NK1, a native isoform of HGF, can also bind to and activate MET.

[0027] In malignant solid tumors, HGF is primarily expressed and released by surrounding stromal cells, enabling tumor and stromal cells to communicate with each other via HGF and creating a microenvironment that contributes to cancer progression. For example, HGF derived from the tumor stroma acts on tumor cells, stimulating not only proliferation and metastasis but also the production of HGF inducers. These HGF inducers, including bFGF, IL-1β, TGF-α, PDGF, and prostaglandin E2 (PGE2), act on stromal fibroblasts, inducing further HGF expression. This creates a feedback loop that drives increased MET activation in the tumor. Thus, the interaction between tumor and stromal cells continuously drives tumor growth, invasion, and metastasis. Furthermore, HGF can also be produced by the tumor itself, a phenomenon that has been detected in renal cell carcinoma, colorectal cancer, breast cancer, glioma, multiple myeloma, as well as synovial sarcoma, osteosarcoma, and fibrosarcoma.

[0028] Dysregulation of the MET pathway in cancer occurs through various mechanisms, including gene mutations, amplification, rearrangement, and protein overexpression. Several MET fusions have been identified, including the fusion between c-MET and TPR (translocated promoter region nuclear basket protein gene) found in mutagenic osteosarcoma cell lines, and the fusion between C-MET and KIF5B (kinesin family member 5B gene) detected in patients with lung adenocarcinoma. Furthermore, mutations at the splice site of MET resulting in exon 14 skipping are a key molecular driver in non-small cell lung cancer (NSCLC). Such exon-skipping mutations have recently been shown to occur in 3%–4% of NSCLC adenocarcinomas, 2% of squamous cell carcinomas, and 1%–8% of other subtypes of lung cancer. These exon-skipping mutations often result in persistent MET activation, driving tumorigenesis via downstream signaling pathways.

[0029] MET activation and intracellular signaling pathways MET activation initiates a series of intracellular signaling pathways, including PI3K / AKT, Ras / MAPK, JAK / STAT, SRC, Wnt / β-catenin, and other signaling pathways, thereby regulating proliferation, motility, migration, and invasion. Under normal physiological conditions, MET is crucial in regulating tissue homeostasis and wound healing, but in cancer, abnormal MET activation drives tumor growth, enhanced metastasis, and drug resistance via these pathways.

[0030] The Ras / MAPK / ERK signaling pathway transmits signals from cell surface receptors, including MET, to DNA in the cell nucleus, where regulation of gene expression occurs. While the signaling cascade involves many different proteins that propagate signals through protein phosphorylation, the pathway can generally be divided into three steps: (i) Ras activation, (ii) kinase signaling cascade, and (iii) translation and transcription regulation. Briefly, MET activation leads to Ras activation, which in turn phosphorylates and activates the protein kinase activity of RAF kinase. In cancer, abnormal Ras activation can lead to tumor growth, evasion of apoptosis, local tissue invasion, and metastasis. RAF kinase then phosphorylates and activates MEK (MEK1 and MEK2), which in turn phosphorylates and activates the MAPK (also known as ERK) protein. MAPK activation modulates the activity of several transcription factors, thereby regulating protein expression. By altering the levels and activity of transcription factors, MAPK alters the transcription of genes crucial to the cell cycle. Depending on the stimulus and cell type, this pathway can transmit signals that result in the prevention or induction of apoptosis or cell cycle progression. For example, the major regulators of angiogenesis involved in the Ras / MAPK / ERK signaling pathway are vascular endothelial growth factor (VEGF) and its homologous receptor VGFR. Activation of the VEGF pathway has been identified in numerous disease processes, including cancer, and within the tumor environment, the VEGFR and MET signaling pathways have been shown to have synergistic effects on tumor growth.

[0031] The phosphatidylinositol 3-kinase (PI3K) / protein kinase B (PKB / AKT) signaling pathway is involved in regulating multiple cellular physiological processes, including metabolism, proliferation, cell survival, growth, and angiogenesis. PI3K is a member of the lipid kinase family and is activated by phosphorylation of the 3-hydroxyl group of phosphatidylinositol lipids in the cell membrane, forming phosphatidylinositol (3,4,5)-trisphosphate (PIP3). PIP3 binds to PKB / Akt in the plasma membrane, allowing pirubate dehydrogenase kinase 1 (PDK1) to access and phosphorylate T308 in the Akt "activation loop," resulting in partial PKB / Akt activation. Subsequent phosphorylation of Akt at S473 in the carboxyl-terminal hydrophobic motif, either by mTOR or DNA-PK, stimulates full Akt activity. Akt activation leads to further substrate-specific phosphorylation events in both the cytoplasm and nucleus, including CREB activation, p27 inhibition, FOXO localization in the cytoplasm, Ptdlns-3ps activation, and mTOR activation. Through these downstream effectors, the PI3K / Akt pathway mediates numerous cellular functions that drive cancer progression, including angiogenesis, metabolism, growth, proliferation, survival, protein synthesis, transcription, and apoptosis.

[0032] The JAK-STAT pathway is essential for a wide range of cytokines and growth factors, leading to critical cellular events such as cell differentiation, hematopoiesis, and immune system development. The JAK / STAT signaling pathway also plays a major role in the growth and survival of different cancer types. Activation of Janus kinase (JAK) by MET results in phosphorylation of signaling molecules and activator of transcription (STAT) proteins, which then dimerize and translocate to the nucleus, where they regulate gene expression and drive tumor growth. For example, STAT3 is a key driver of tumorigenesis, regulating the expression of many oncogenes, including BCL-XL, c-MYC, Mell, Survivin, BEGF, HIF-1α, HGF, IL-12, and MMPs. In this way, the JAK / STAT pathway drives tumor progression by enhancing cell proliferation, angiogenesis, metastasis, and immune escape.

[0033] The Wnt / p-catenin signaling pathway is a conserved signaling axis involved in diverse physiological processes such as proliferation, differentiation, apoptosis, migration, invasion, and tissue homeostasis. Activation of the Wnt / p-catenin signaling pathway leads to an increase in cytosolic P-catenin concentration, which translocates to the nucleus and interacts with T cell-specific factor (TCF) / lymphoid enhancer binding factor (LEF) and its co-activators, such as Pygopus and Bcl-9. This then enhances the expression of target genes, including c-Myc, cyclin DI, and CDKN1A, which drive cancer stem cell regeneration, cell proliferation, and differentiation, and therefore plays a crucial role in tumorigenesis and therapeutic response. Thus, by modulating various oncogenetic signaling pathways, MET is a major driver of tumor growth, survival, invasion, and metastasis.

[0034] MET kinase inhibitors Several drugs targeting MET or HGF, including small molecule inhibitors and monoclonal antibodies, are under development. Monoclonal antibodies currently FDA-approved or undergoing clinical evaluation include anti-MET antibodies (e.g., onartuzumab and emibetuzumab), anti-HGF antibodies (e.g., ficratuzumab and rilotumumab), and anti-MET / EGFR bispecific antibodies (e.g., amivantamab). These therapies prevent HGF from binding to MET, thereby halting MET activation. Furthermore, many small molecule MET inhibitors, including capatinib, tepotinib, crizotinib, cabozantinib, MGCD265, AMG208, artiratinib, and golvatinib, are FDA-approved for the treatment of cancer. Of these, two selective MET inhibitors, capmatinib (Tabrecta®) and tepotinib (Tepmetko®), are FDA approved for the treatment of patients with advanced NSCLC with MET exon 14 skipping mutations. Cabozantinib (Cabometyx®) is FDA approved for the treatment of locally advanced or metastatic differentiated thyroid cancer.

[0035] Small molecule MET-specific inhibitors can be divided into two functionally distinct classes: type I inhibitors (e.g., crizotinib, capatinib, tepotinib, and savolitinib) that preferentially bind to the active conformation of MET, and type II inhibitors (e.g., cabozantinib and gresatinib) that preferentially bind to the inactive conformation of MET. Furthermore, selective MET inhibitors include adenosine triphosphate competitors and adenosine triphosphate non-competitives (e.g., tivantinib). Type I MET inhibitors are further subdivided into type Ia inhibitors (e.g., crizotinib) that interact with the solvent front G1163 residue, and type Ib inhibitors (e.g., capmatinib, tepotinib, and savolitinib) that bind to the kinase domain.

[0036] Resistance to type I and type II MET inhibitors is often associated with MET kinase domain mutations. For example, mutations at kinase domain residues D1228 and Y1230 confer resistance to type I MET inhibitors in vitro by weakening the interaction between the drug and the MET kinase domain. Resistance to all type I MET inhibitors has been clinically identified, and patients have secondary mutations at these locations. Furthermore, mutations at the solvent front G1163R confer resistance to the type Ia MET inhibitor crizotinib, but not to type Ib MET inhibitors such as tepotinib, savolitinib, or capatinib in vitro. Type II MET inhibitors retain varying degrees of efficacy against many cancers with these mutations that render type I inhibitors ineffective. However, the MET L1195V mutation confers resistance to type II MET inhibitors, and it has been suggested that resistance to type II MET inhibitors may be driven by high levels of local amplification of the MET exon 14 mutant allele. Growing evidence suggests that MET mutations are a consistent mechanism of acquired resistance and post-tyrosine kinase inhibition in several oncogene-driven molecular subsets of cancer. Therefore, resistance to MET inhibitors has become a major challenge to the clinical efficacy of targeted therapies. Given the considerable resistance that mutations confer to MET inhibitors, there is a significant unmet clinical need for MET inhibitors that can not only maintain efficacy against tumors but also against tumors with acquired MET-resistant mutations and other mutations.

[0100] The following exemplary embodiments are representative of the systems and methods described herein and are not intended to limit the scope of the claims provided herein.

[0101] Example 1: In vitro MET kinase inhibitory activity of compound 1 Compound 1 was tested in biochemical assays (Table 1) and cellular assays (Table 2) to evaluate its activity against both wild-type and mutant MET kinase family members in multiple independent experiments.

[0102] Methods: The biochemical activity of compound 1 was determined by a reaction biology kinase hotspot assay. All kinase targets were reacted with 10 μM ATP. Appropriate substrates were diluted in reaction buffer containing 20 mM HEPES (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.01% Brij35, 0.02 mg / mL BSA, 0.1 mM sodium orthovanadate, 2 mM DTT, and 1% DMSO, as well as the appropriate substrate. After incorporating the kinase into the solution, compound 1 was added using a 10-point 3x dose curve, starting at 10 μM, 3 μM, or 1 μM as the maximum concentration during a 20-minute pre-incubation at room temperature. 33 P-ATP was added to the reaction mixture to initiate the reaction, which was incubated at room temperature for 2 hours. Kinase activity was detected by the P81 filter-bound method: after incubation, the reaction mixture was spotted onto P81 ion-exchange filter paper (Whatman). Unbound phosphate was removed by extensive washing of the filter in 0.75% phosphoric acid. After subtracting background from a control reaction containing inactive enzyme, kinase activity data was expressed as the percentage of residual kinase activity in the test sample compared to the vehicle reaction. Maximum half-volume inhibitory concentration (IC50) values ​​were calculated using the conversion ratio inhibition with Dotmatics Knowledge Solutions Studies curve fitting.

[0103] Cell viability profiling was performed on manipulated TPR-MET Ba / F3 cells. Ba / F3 manipulated cells were placed in 3 × 10⁶ wells of culture medium in a 96-well plate. 3 Cells were seeded in wells. The following day, the compound was diluted in PBS and added to plates to a final concentration ranging from 0.46 nM to 10 μM in 0.1% DMSO, with 0.1% DMSO in 10% FBS culture medium as a negative control. Cells were incubated at 37°C in 5% CO2 for 3 days. Then, the CTG reagent was added, and the plates were incubated at room temperature for 15–20 minutes according to the manufacturer's instructions. The plates were read in luminescence mode, and the EC50 values ​​were calculated by dose-response regression curve fitting using a four-parameter analysis method.

[0104] Results: Biochemical assays tested the potency of compound 1 against both wild-type and mutant c-Met family members. Table 1 lists the mean potency of compound 1 inhibition against the enzymes. c-Met enzymes with kinase domain mutations showed IC50 values ​​ranging from the most potent 0.6 nM for the M1250I mutation to the least potent 10.6 nM for the G1163R mutant enzyme. The mean IC50 concentration across all tested c-Met and c-Met mutant enzymes was 3.2 nM. The inhibition of cell proliferation by compound 1 was evaluated across a panel of IL-3-independent mouse manipulated Ba / F3 cell lines by overexpression of translocated promoter region (TPR)-MET fusion genes with specific MET mutations. Cell viability was measured using a CTG assay 3 days after compound 1 treatment in multiple independent experiments. As shown in Table 2, the EC50 values ​​of compound 1 ranged from 1.0 nM (TPR-METL1195F) to 613 nM (TPR-METG1163R) in mutant cells, and the EC50 values ​​were <60 nM in 18 of the 19 strains tested. Furthermore, compound 1 performed better than capmatinib, tepotinib, cabozantinib, and merestinib.

[0106] [Table 2]

[0107] Example 2: Determination of antitumor activity in a MET mutant mouse xenograft model Compound 1, a MET inhibitor, inhibits clinically observed secondary mutations known to drive resistance to approved MET kinase inhibitors. Preclinical studies have shown that compound 1 is potent against activating mutations in non-small cell lung cancer. The mutations studied include, among others, MET exon 14 skipping mutations and MET amplification with low nanomolar biochemical and cellular target binding half-opinion inhibitory concentrations (IC50) values. As shown in Table 3 and Figures 1-3, the antitumor activity of compound 1 was evaluated in xenograft models exhibiting MET activating mutations, including MET exon 14 skipping mutations, MET amplification, and BAF3 TPR-MET D1228N acquired resistance mutations. Oral administration of compound 1 was generally well-tolerated and effective in mouse xenograft models of MET-driven cancer. Furthermore, compound 1 performed better than capmatinib in mouse xenograft models with resistant MET mutations.

[0108] Method: In the right flank of thymus-deficient BALB / c nude mice, 5x10 6 EBC-1 cells, 1x10 6 BaF3 TPR-MET D1228N cells or LU2503 tumors with MET mutations, 2-3 mm in size. 3 Fragments were subcutaneously inoculated. Mice were grouped based on their initial tumor volume and body weight, so that the mean values ​​were the same for each treatment group. Oral administration of compound 1 and / or capatinib was used when the tumor volume was approximately 200-300 mm. 3 The study began when the target was reached and continued for 10–21 days. Animals were monitored for tumor growth, weight changes, and overall health / behavior.

[0109] Results: Compound 1 had good tolerance, no weight loss was observed, and it was effective in a xenograft model of athymic nude mice with MET mutant cancer at doses up to 60 mg / kg BID daily. Dose-dependent tumor growth inhibition was observed in the LU2503 PDX model of lung cancer with MET gene amplification and exon 14 deletion, the EBC-1 CDX model with MET amplification, and the Ba / F3 TPR-MET fusion model with the MET D1228N resistant mutation. The lowest doses of 2 and 6 mg / kg of Compound 1 resulted in moderate TGIs in all three models (the average TGI for LU2503 was 43 - 77% for 2 - 6 mg / kg of Compound 1 respectively; the average TGI for EBC-1 was 25 - 52% for 2 - 6 mg / kg of Compound 1 respectively; the average TGI for Ba / F3 TPR-MET D1228N was 26 - 44% for 2 - 6 mg / kg of Compound 1 respectively). Compound 1 resulted in tumor regression at high doses in all three models (the average TGI for LU2503 was 110 - 113% for 20 - 60 mg / kg of Compound 1 respectively; the average TGI for EBC-1 was 110% for 60 mg / kg of Compound 1; the average TGI for Ba / F3 TPR-MET D1228N was 128% for 60 mg / kg of Compound 1, and p < 0.0001 for all). These data identify that Compound 1 has potent antitumor activity in exon 14 deletion-mediated cancer, gene amplification cancer, and D1228N mutant MET-driven cancer.
