Background

FIIN-3 is an inhibitor of FGF receptors (FGFRs; IC₅₀s = 13, 21, 31, and 35 nM for recombinant FGFR1-4, respectively).¹ It is selective for FGFRs over a panel of 456 kinases at a concentration of 1 μM, however, it does inhibit EGFR (IC₅₀ = 204 nM). FIIN-3 inhibits growth of Ba/F3 cells that are dependent on the kinase activity of wild-type FGFR1-4 as well as gatekeeper mutant FGFR2 and FGFR3 (EC₅₀s = <1-69 nM) and inhibits FGFR-dependent signaling in a concentration-dependent manner in FGFR2^TEL/V564M-dependent Ba/F3 cells. FIIN-3 also inhibits growth in a panel of cancer cell lines (EC₅₀s = 1.4-499 nM).

Protocol

Cell experiment:

TEL-FGFR2–transformed Ba/F3 cells are seeded in a 96-well plate and are treated with each concentration of FIIN-3. After 72 h the cells are assessed by MTS tetrazolium assay[1].
