R916562 is a potential and selective Axl/VEGF-R2 dual inhibitor with IC50s of 136 and 24 nM, respectively.

R916562 delays and inhibits tumor growth in MDA-MB-231 human breast cancer xenograft model. R916562 also shows efficacy in the Caki-1 human renal carcinoma xenograft model. R916562 treatment at 85 mg/kg or 125 mg/kg orally b.i. d for 21 days results in statistically significant tumor growth inhibitions of 69% or 83% respectively. R916562 shows 73% reduction in fibroblast growth factor-induced neovascularization in a mouse corneal micropocket assay at a dose of 100 mg/kg and 50% reduction at 50 mg/kg[1].
