A potent EGFR kinase inhibitor
PD 153035 is a potent, reversible inhibitor of EGFR kinase (Ki = 5.2 pM; IC50 = 29 pM).1 It less effectively inhibits HER2 (IC50 = 2.3 µM) and has little effect on several other receptor and non-receptor tyrosine kinases.1 PD 153035 has been shown to rapidly suppress autophosphorylation of EGFR in ?broblasts and human epidermoid carcinoma cells, as well as to selectively block EGF-mediated cellular processes, including mitogenesis and early gene expression.2,3
