Brief Description

FIIN-2, an irreversible, pan-FGFR inhibitor, inhibits FGFR1/2/3/4 with IC50 of 3.09 nM, 4.3 nM, 27 nM and 45.3 nM, respectively.
Description

FIIN-2 is a potent, selective, irreversible and the next-generation covalent FGFR inhibitor. FIIN-2 is the first inhibitor that can potently inhibit the proliferation of cells dependent upon the gatekeeper mutants of FGFR1 or FGFR2, which confer resistance to first-generation clinical FGFR inhibitors such as NVP-BGJ398 and AZD4547. FIIN-2 also binds in the DFG-out mode despite lacking a functional group necessary to occupy the pocket vacated upon the DFG-out flip.
In Vitro

FIIN-2 potently inhibits WT FGFRs (EC50s in the 1- to 93-nM range) and the gatekeeper mutant of FGFR2 (EC50 of 58 nM). FIIN-2 also moderately inhibits EGFR, with an IC50 of 204 nM. FIIN-2 inhibits proliferation of FGFR1-4 Ba/F3 cells with EC50s in the single- to double-digit nanomolar range and are especially potent against FGFR2, with EC50s in the 1-nM range. FIIN-2 shows good potency against gatekeeper mutant V564F.
In Vivo

Treatment of fish in the embryonic state with either FIIN-2 causes defects to the posterior mesoderm similar to the phenotypes reported following genetic knockdown of FGFR or treatment with other reported FGFR inhibitors. FIIN-2 causes mild or severe phenotypes to the tail morphogenesis in all treated embryonic zebrafish.
