FGFR inhibitors

FGFR (Fibroblast growth factor receptor),a kind of glycoproteins with extracellular immunoglobulin (Ig)-like domains, which consists of five members FGFR-1, FGFR-2, FGFR-3, FGFR-4 and FGFR-5 are tyrosine kinase receptors which mediate signaling from their high-affinity ligands, fibroblast growth factors (FGFs). Active FGFRs stimulate tyrosine phosphorylation and activation of a number of signaling molecules: Shc, PI3K, SRC, PLC, Crk, SH2 domain containing phosphatase-2 (SHP-2), p38, STAT1/3 and FGFR substrate2 (FRS2). Phosphorylation of the docking protein FRS2 recruits and activates the Grb2/Sos1 complex, which then interacts with Ras to activate the MAPK pathway.
