      FRIN-1
      Notes: FRIN-1 is 24-fold less potent against Tel-FGFR1 (EC50 = 340 nM) and 100-fold less potent against Tel-FGFR3 (EC50 = 1040 nM)-transformed Ba/F3 cells. Assay of recombinant FGFR1 measured in Z′-lyte format demonstrated that FIIN-1 is approximately 2.3 times more potent than FRIN-1 in vitro.

      FIIN1 is a very potent covalent inhibitor for FGFR1 and FGFR3 with IC50 values below 15 nM (in vitro). Convincing proof of covalent binding mode by pharmacological and genetic controls. Selectivity of...
