FIIN-3 is an irreversible inhibitor of FGFR with an IC50 of 13.1, 21, 31.4, and 35.3 nM for FGFR1, FGFR2, FGFR3 and FGFR4, respectively. FGFR1|13.1 nM (IC50)|FGFR2|21 nM (IC50)|FGFR3|31.4 nM (IC50)|FGFR4|35.3 nM (IC50)
FIIN-3 potently inhibits both WT FGFRs (EC50 in the 1- to 41-nM range) and the gatekeeper mutant of FGFR2 (EC50 of 64 nM). FIIN-3 also strongly inhibits EGFR, with an EC50 of 43 nM. FIIN-3 shows good potency against gatekeeper mutant V564F; FIIN-3 also is potent against the gatekeeper-plus-1 mutant E565K; FIIN-3 also displays antiproliferative activity (with an EC50 of 135 nM) against Ba/F3 cells transformed by the EGFR vIII fusion protein, which has a WT EGFR kinase domain. FIIN-3 shows even better activity against EGFR mutant L858R (EC50 of 17 nM) and moderate activity, displaying an EC50 of 231 nM, against the EGFR mutant L858R/T790M mutant. In WT FGFR2 Ba/F3 cells, FIIN-3 completely inhibits the FGFR2 autophosphorylation on Tyr656/657 at concentrations as low as 3 nM. In FGFR2 V564M Ba/F3 cells, FIIN-3 is capable of inhibiting the FGFR2 mutant V564M autophosphorylation with partial inhibition at 100 nM and complete inhibition observed at 300 nM[1].
