PD153035 (NSC-669364) hydrochloride is an effective and selective inhibitor of EGFR (Ki/IC50: 5.2/29 pM, in cell-free assays); little inhibitory against FGFR, PGDFR, InsR, CSF-1 and Src.

PD153035 hydrochloride (ZM 252868) is a effective and selective inhibitor of EGFR (Ki: 5.2 pM, IC50: 29 pM); few influence against FGFR, PGDFR, InsR, CSF-1, and Src.

PD153035 is a ATP-competitive EGFR inhibitor with an IC50 and Ki of 25 and 6 pM. PD153035 effectively blocks the enhancement of mitogenesis, induction of early gene expression, and oncogenic transformation that occur in response to EGF receptor stimulation. With human fibroblasts and epidermoid carcinoma cells, PD153035 at nanomolar concentrations rapidly inhibits EGFR autophosphorylation. With breast and ovarian cancer cells, PD153035 not only blocks cell growth via inhibition of EGFR, but also upregulates the expression of the tumor suppressor retinoic acid receptor-beta 2 (RAR-beta2).
