pd153035

Description: PD153035 is reported to be a novel, potent, specific, and ATP competitive inhibitor of EGFR (Epidermal growth factor receptor) tyrosine kinase with Ki and IC50 of 5.2 pM and 29 pM in cell-free assays, and to a lesser degree, of the closely related HER2/neu receptor; PD153035 inhibits EGF-dependent EGFR phosphorylation in a variety of human cancer cell lines over-expressing EGFRs, which include A431, Difi, DU145, MDA-MB-468, ME180 and C4i, with IC50 of 0.22 uM, 0.3 uM, 0.4 uM, 0.68 uM, 0.95 uM and 2.5 uM respectively. In addition, PD153035 could reverse ABCG2-mediated MDR in vitro (in human NSCLC and transfected cells overexpressing ABCG2) and in vivo. One of the major mediators of multidrug resistance (MDR) in non-small cell lung cancer (NSCLC) is the overexpression of ATP-binding cassette subfamily G member 2 (ABCG2). Therefore, PD153035 may be a promising therapeutic strategy for NSCLC overexpressing ABCG2.
