Background:

Lapatinib (also known as GW572016), a member of the 4-anilinoquinazoline class of kinase inhibitors, is a potent, reversible and selective small-molecule inhibitor of both epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER-2) tyrosine kinases that inhibits recombinant EGFR and HER-2 tyrosine kinases in cell-free biochemical kinase assays with values of 50% inhibition concentration IC50of 10.8 nmol/L and 9.3 nmol/L respectively. Lapatinib interferes with the adenosine triphosphate binding in the tyrosine kinases domains of both EGFR and HER-2 resulting in the inhibition of auto-phosphorylation and resultant downstream signaling activities (such as cellular proliferation and survival).
