AG-494

AG-494 (Tyrphostin AG 494) is a potent and selective EGFR tyrosine kinase inhibitor (IC50=0.7 μM) . AG-494 inhibits the autophosphorylation of EGFR, ErbB2, HER1-2 and PDGF-R with IC50s 1.1, 39, 45 and 6 μM, respectively. AG-494 blocks Cdk2 activation and inhibits EGF-dependent DNA synthesis[1][2][3].
