FIIN-2

FIIN-2 is an irreversible FGFR inhibitor with IC₅₀ values of 3.09, 4.3, 27, and 45.3 nM for FGFR1, FGFR2, FGFR3, and FGFR4, respectively. It has been shown to inhibit cell proliferation of transformed Ba/F3 cell lines and demonstrates antiproliferative activity in cells dependent upon the gatekeeper mutants of FGFR1 or FGFR2. By inhibiting FGFR in a zebrafish developmental model, FIIN-2 caused mild to severe alterations in tail morphogenesis similar to the phenotypes reported following genetic knockdown of FGFR.

FIIN 2 is FGFR inhibitor. It can be used in biological study of DFG-out mode of inhibition by an irreversible Type-1 inhibitor capable of overcoming gate-keeper mutations in FGF receptors
