Beschreibung

General description

A cell-permeable, ATP-binding site-targeting alkynamidopyrimidine compound that acts as a potent and irreversible inhibitor of erbB activities (IC₅₀ = 0.3, 1.1, and 0.5 nM for erbB-1, erbB-2, and erbB-4, respectively). Inhibits EGF- and heregulin-induced erbB autophosphorylation in NIH3T3-erbB-1 and in MDA-MB-453 cells (IC₅₀ = 2.5 and 24 nM, respectively).
