How to use

In Vitro:

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. In human umbilical vein endothelial cells (HUVECs), Ki8751 (1 nM–100 nM) effectively decreases VEGF-stimulated cell proliferation and vasculature permeability. In metastatic colorectal cancer (CRC) cells MIP, RKO, SW620, and SW480, but not in HCT116, Ki8751 (10 nM) increases cellular senescence.

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.
