Description

General description

A potent, cell-permeable, irreversible, ATP-competitive and selective inhibitor of EGF receptor (EGFR) tyrosine kinase activity (IC₅₀ = 0.70 nM). Does not inhibit other protein kinases. Acts by binding to the catalytic domain of the EGFR with a 1:1 stoichiometry and alkylating Cys⁷⁷³. Excellent antitumor agent in vivo.
