BFH772 is an inhibitor of VEGF receptor 2 (VEGFR2; IC50 = 0.0027 μM for the human receptor). It is selective for human VEGFR2 over mouse VEGFR2 and human VEGFR1 and VEGFR3 (IC50s = 1.5, 1.7, and 1.1 μM, respectively), as well as 40-fold selective over B-RAF, RET, and Tie2. BFH772 inhibits VEGF-induced proliferation of human umbilical vein endothelial cells (HUVECs; IC50 = <0.01 nM). It inhibits VEGF-induced increases in tissue weight and Tie2 levels in an angiogenesis chamber implant model in mice when administered at doses of 1 and 3 mg/kg per day. BFH772 (3 mg/kg per day) inhibits primary tumor and metastasis growth in a B16 melanoma mouse model.
