Use of PD-161570

PD-161570 is a potent and ATP-competitive human FGF-1 receptor inhibitor with an IC50 of 39.9 nM and a Ki of 42 nM. PD-161570 also inhibits the PDGFR, EGFR and c-Src tyrosine kinases with IC50 values of 310 nM, 240 nM, and 44 nM, respectively. PD-161570 inhibits PDGF-stimulated autophosphorylation and FGF-1 receptor phosphorylation with IC50s of 450 nM and 622 nM, respectively[1][2]. PD-161570 is also a bone morphogenetic proteins (BMPs) and TGF-β signaling inhibitor[3].

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 at day 8[1]. 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[2]. PD-161570 can potent inhibit basic fibroblast growth factor (bFGF)-mediated angiogenesis[4]. Cell Proliferation Assay[1] Cell Line: Vascular smooth muscles cells (VSMCs) Concentration: 0.1 µM, 0.3 µM, 1 µM Incubation Time: 1 day, 3 days, 6 days, 8 days Result: Inhibited VSMC proliferation in a dose dependent fashion with an IC50 of 0.3 µM at day 8.
