Description

General description

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, PDGFRα, and FGFR-2 only at much higher concentrations (IC₅₀ = 40, 67, and 170 nM, 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 proliferation in vitro and tumor growth in mice and rats (5 to 20 mg/kg, daily p.o.) in vivo.
