Biological Activity

Potent, irreversible inhibitor of ErbB2 (HER2) and EGFR (IC50 values are 33 and 34 nM respectively). Suppresses ligand-induced EGFR autophosphorylation and cell proliferation in NCI-H1975 cells containing L858R and T790M mutations. Circumvents mechanisms of resistance to Iressa (Cat. No. 3000) in non-small-cell lung cancer cells.

Compound Libraries
