Abstract

The aberrant activation of Fibroblast Growth Factor (FGF) and FGF receptor (FGFR)-mediated signaling pathways are associated with Cancer development, including hepatocellular carcinoma (HCC). A novel series of imidazo[1',2':1,6]pyrido[2,3-d]pyrimidine, containing an acrylamide covalent warhead, were synthesized as selective FGFR 1-4 inhibitors. Compound 7n was identified as the most potent inhibitor against FGFR1, 2, and 4, with IC50 values of 8/4 nM (FGFR1/2) and 3.8 nM (FGFR4), and the covalent docking analyses suggested that 7n form a covalent adduct with cysteine residue on the hinge or p-loop of FGFR. Compound 7n exhibited a favorable pharmacokinetic profile and significant in vivo antitumor efficacy in human liver Cancer xenograft mouse models (xenograft, FGF/FGFR-dependent HCC cells).
