AEE788 inhibits EGFR and VEGF receptor tyrosine kinases in the nM range (IC50:EGFR 2 nm, ErbB2 6 nm, KDR 77 nm, and Flt-1 59 nm). In cells, growth factor-induced EGFR and ErbB2 phosphorylation is also efficiently inhibited (IC50:11 and 220 nm, respectively). AEE788 demonstrates antiproliferative activity against a range of EGFR and ErbB2-overexpressing cell lines (including EGFRvIII-dependent lines) and inhibits the proliferation of epidermal growth factor- and VEGF-stimulated human umbilical vein endothelial cells. Treatment of cutaneous SCC cells with AEE788 leads to dose-dependent inhibition of EGFR and VEGFR-2 phosphorylation, growth inhibition, and induction of apoptosis.
