A cell-permeable quinolyloxyphenyl-urea compound that acts as a VEGFR-2-selective inhibitior in both cell-based (IC50 = 0.9 nM in VEGF-induced receptor phosphorylation) and cell-free (IC50 = 4.0 nM in kinase reactions) assays. It inhibits c-Kit, PDGFRa, and FGFR-2 only at much higher concentrations (IC50 = 40, 67, and 170 µM, respectively, in cell-based assays), while exhibiting no effect against eight other commonly studied receptor and non-receptor kinases even at concentrations as high as 10 µM. Effectively blocks VEGF-dependent, but not VEGF-independent, cell proliferationin vitro.
