Description

PD-161570 is a selective FGFR inhibitor (IC50 values are 40, 262 and 3700 nM for FGFR, PDGFR and EGFR respectively). PD 161570 had about 5- and 100-fold greater selectivity toward the FGF-1 receptor (IC50 = 40 nM) compared with the PDGFbeta receptor (IC50 = 262 nM) or EGF receptor (IC50 = 3.7 microM) tyrosine kinases, respectively. In addition, PD 161570 suppressed constitutive phosphorylation of the FGF-1 receptor in both human ovarian carcinoma cells (A121(p)) and Sf9 insect cells overexpressing the human FGF-1 receptor and blocked the growth of A121(p) cells in culture. The results demonstrate a novel synthetic inhibitor with nanomolar potency and specificity towards the FGF-1 receptor tyrosine kinase.

How to use

In Vitro:

PD-161570 (Compound 6c; 0.1-1 µM; 1-8 days; VSMCs) treatment inhibits PDGF-stimulated vascular smooth muscle cell proliferation in a dose dependent fashion with an IC50 of 0.3 µM on day 8. PD-161570 suppresses constitutive phosphorylation of the FGF-1 receptor in both human ovarian carcinoma cells (A121(p)) and Sf9 insect cells overexpressing the human FGF-1 receptor and blocked the growth of A121(p) cells in culture. PD-161570 can potently inhibit basic fibroblast growth factor (bFGF)-mediated angiogenesis.
