AG 538 is a potent, competitive inhibitor of IGF-IR (IGF-1 receptor kinase, IC50 = 400 nM). Reaction is competitive with respect to IGF-1R substrate. Also inhibits the phosphorylation of PTK substrate poly(Glu,Tyr) by IGF-1R, IR, EGF-R, and Src (IC50 = 60 nM, 113 nM, 370 nM, and 2.4 muM, respectively). Inhibits the phosphorylation of PKB at a much higher concentration (IC50 = 76 muM).
