VEGFR tyrosine kinase inhibitor II is a pyridinyl-anthranilamide compound that inhibits the kinase activities of VEGFR2 (KDR), VEGFR1 (FLT1), and c-Kit (IC50s = 20, 180, and 240 nM, respectively).1 It displays minimal activity against c-Src and EGFR (IC50s = 7 and 7.3 µM, respectively) and is inactive against Cdk1, c-Met, IGF-1R, and PKA (IC50s > 10 µM).1 VEGFR tyrosine kinase inhibitor II has been investigated for its potential to inhibit tumor induced angiogenesis.[1]
