Ki8751 potently and selectively inhibits VEGFR2 with IC50 of 0.9 nM. Ki8751 also inhibits PDGFRα, c-Kit, and FGFR-2, with much higher IC50 values (40 nM–170 nM). Except for these several kinases, Ki8751 doesn't disturb other kinases, including HGFR, EGFR, and InsulinR, even at 10 μM. [1]
In human umbilical vein endothelial cells (HUVECs), Ki8751 (1 nM–100 nM) effectively decreases VEGF-stimulated cell proliferation and vasculature permeability. [2]
In metastatic colorectal cancer (CRC) cells MIP, RKO, SW620, and SW480, but not in HCT116, Ki8751 (10 nM) increases cellular senescence. [3]

| In vivo |
In nude mice bearing human tumor xenografts of GL07, St-4, LC6, DLD-1, and A375 cells, Ki8751 (20 mg/kg) inhibits tumor growth. In nude rat xenograft models of LC-6 cells, Ki8751 (5 mg/kg) completely inhibits tumor growth without affecting body weight. [1]
