TECHNICAL FIELD

The present invention belongs to the field of medicament synthesis, and in particular relates to an FGFR4 inhibitor, preparation method and pharmaceutical use thereof.

TECHNICAL BACKGROUND

Fibroblast growth factor (FGF) is a family of 22 structurally related polypeptides with diverse biological activities that can regulate cell proliferation, differentiation and migration, and play a major role in the process of limb development, angiogenesis, tissue repair, tumor formation and the like. (Eswarakumar et al., 2005 Cytokine Growth Factor Rev 16: 139-149; Ornitz and Itoh, 2001 Genome Bio 12: Reviews 3005).

The receptors for FGF (FGFR) belong to a family of RPTK of receptor tyrosine kinases. Four FGFRs, FGFR1, FGFR2, FGFR3 and FGFR4, have been identified to date (Ulrich and Schlessinger, 1990 Cell 61:203). The interaction between receptors and the corresponding ligands FGF leads to receptor dimerization and autophosphorylation, thereby initiating multiple downstream signaling cascades including MAPK and AKT (Powers et al., 2000 Endocr Relat Cancer 7: 165-197).

FGFR1-3 has been found to be overexpressed, mutated or translocated in a variety of tumors (including myeloma, breast cancer, stomach cancer, colon cancer, bladder cancer, pancreatic cancer, and hepatocellular carcinoma), and considered to be driver gene in cancer (Chesi et al., 2001 Blood 97:729-726; Gowardhan et al., 2005 Br J Cancer 92: 320-327; Jaakkola et al., 1993 Int J Cancer 54:378-282; Jang et al., 2001 Cancer Res 61: 3541-3543). Some FGFR inhibitors have also been developed in the clinical and preclinical development process. However, previous studies have shown that FGFR1 can regulate the level of phosphate, so pan-FGFR inhibitors may pose safety concerns.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths in China and is one of the fastest growing cancers every year (Shariff et al., 2009 Expert Rev Gastroenterol Hepato 13: 353-367). Currently, the first-line treatment option is sorafenib, there are no approved second-line treatment, and there is still a need for targeted therapy with anti-tumor agents.

Overexpression of FGF19 is present in 5-10% of hepatocellular carcinoma patients, whereas FGFR4 is a dominant FGFR present in human hepatocytes, and its high expression in hepatocytes is found to be associated with the aggressiveness of hepatocellular tumors. Therefore, FGFR4 plays a very important role in liver cancer. In addition, the interaction of FGF19 and FGFR4 is also considered to be related to the aggressiveness of other cancers (such as gastric cancer, prostate cancer, lung cancer, colorectal cancer, pancreatic cancer, and ovarian cancer) (Ye et al, 2011 Cancer 5304-5313; Xu et al, 2011 BMC Cancer 11:84; Fawdar et al, 2013 PNAS 110:12426-12431).

At present, some FGFR inhibitors have entered into the clinical research stage as anti-tumor drugs, but mostly inhibitors against FGFR1, 2 and 3, with weaker inhibition of FGFR4 activity. The inhibition of FGFR1-3 has on-target side effects such as hyperphosphatemia. Highly selective inhibitor of FGFR4 can effectively treat cancer caused by abnormal FGFR4 signaling, and can avoid the side effects caused by FGFR1-3 inhibition such as hyperphosphatemia. Highly selective small molecule inhibitors against FGFR4 have significant application prospects in the field of anti-tumor targeted therapy. Therefore, the development of a novel anti-tumor agent that can selectively target FGFR4 as a good drug candidate will meet the needs of domestic liver cancer and other anti-tumor target therapy, and have the advantages of better safety and higher selectivity.

Biological Test and Evaluation

I. In Vitro Biochemical Kinase Analysis of FGFR4

FGFR4 Caliper Assay was used in the present invention to determine the inhibitory activities of the compounds against FGFR4. The detailed experimental procedure was as follows.

1. The kinase reaction in the present invention was carried out in a 384-well plate, and 12.5 μM. of FGFR4, 65 μM of ATP and 1 μM of peptide (5 Fluo Ahx KKKKEEINTFFG NH2) were respectively added into the following reaction system.

2. A reaction system is a mixture solution of 50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween 20, 0.02% BSA, 0.6% DMSO, 10 mill beta glycerol phosphate and 10 μM sodium orthovanadate and 16 mM MgCl₂.

3. The reaction system was incubated at 30° C. for 40 minutes.

4. The reaction was terminated by adding a stop solution (100 mM HEPES, pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA and 0.015% Brij35)

5. The culture plate with the terminated kinase reaction was transferred to the Caliper LC 3000 workstation to read the data, the phosphorylated and unphosphorylated peptides were separated by using the Caliper microfluid migration shift technique, and the analyte was transferred by allowing a constant buffer flow through the chip, the migration of the substrate peptide was monitored by the labeled fluorescent signal, and the kinase activity was calculated by using the amount of the phosphate-based peptide formed.

6. Finally, IC₅₀ values were determined by non-linear regression analysis of percent inhibition at different compound concentrations. The test results for the enzymatic activities of the compounds of the specific examples were shown in Table 1,

II. FGFR4 Cell Proliferation Experiment

Cell Titer Glo (CTG) experiment was used in the present invention to evaluate the functional effects of the compounds on cell proliferation. Huh: hepatocellular carcinoma cells (Catalog No, TChU182) from the Chinese Academy of Sciences cell bank were cultured in DMEM with high glucose (Gibco, cat. No. 1773536), 10% fetal bovine serum (Gibco, 10099-141) at 37° C., in a 5% CO₂ incubator. Compound-mediated inhibition of cell proliferation/survival was assessed by quantification of cellular ATP levels using CTG reagent (Promega, #G7573). The specific experimental procedure was as follows:

1. The cells were seeded into a tissue culture medium-treated 96-well plate (Costar #3904) at 3500 cells/well/90 μL of fresh medium:

2. 10 μL of medium containing a compound concentration of 10 fold of its final test concentration was added;

3. The dose effect was evaluated by a 5-fold serial dilution of the test compound, starting from 10 μM.

4. After cells incubation for 3 days at 37° C. under 5% CO₂, the effect of the inhibitor on cell proliferation was quantified after adding 50 μL of CTG and testing with luminescence.

5. The concentration of the compound (EC₁₀) leading to half maximal growth inhibition and the concentration of compound (Absolute IC₅₀) leading to absolute half growth inhibition were determined using a four-parameter curve fit in Graphpad Prism in a plate reader (M1000, Tecan). The test results of cell activities for the compounds of specific examples were shown in Table 1.
