Description

General description

A cell-permeable aminopyrimidine oxime compound that potently inhibits EGFR/ErbB1/HER1, ErbB2/HER2/neu, and ErbB4/HER4 kinase activity (IC₅₀ = 22, 38 and 21 nM, respectively) in an ATP-competitive manner and effectively suppresses cellular receptor phosphorylation (IC₅₀ = 223 and 107 nM against basal HER2 and EGF-induced EFGR phosphorylation, respectively, in SKBR3 and A431 cultures) as well as HER2- and EGFR-dependent cancer cell proliferations (IC₅₀<1µM), while exhibiting much reduced or little activity against a panel of 202 other kniases. Reported to be orally available and blood-brain barrier permeant in both mice and rats and be efficacious in inhibiting tumor growth in several murine xenograft models (100 to 200 mg/kg/day, p.o.) in vivo.
