Description: KRC-108 is a multiple kinase inhibitor. KRC-108 is a potent inhibitor of Ron, Flt3 and TrkA as well as c-Met. KRC-108 inhibited oncogenic c-Met M1250T and Y1230D more strongly than wild type c-Met. The anti-proliferative activity of KRC-108 was measured by performing a cytotoxicity assay on a panel of cancer cell lines. The GI(50) values (i.e., 50% inhibition of cell growth) for KRC-108 ranged from 0.01 to 4.22 μM for these cancer cell lines. KRC-108 was also effective for the inhibition of tumor growth in human HT29 colorectal cancer and NCI-H441 lung cancer xenograft models in athymic BALB/c nu/nu mice. This molecule should serve as a useful lead for inhibitors targeting kinases and may lead to new therapeutics for the treatment of cancer.
