MK-2461 is a novel inhibitor that targets multiple proteins and competitively binds to ATP sites, specifically inhibiting the activated c-Met protein with an average inhibitory concentration (IC50) of 2.5 nM.

Crizotinib (PF-02341066) is an ATP-competitive small-molecule tyrosine kinase inhibitor of c-MET (IC50: 8 nM) and ALK (IC50: 20 nM) receptors.

AMG-337 is an effective and highly specific ATP-competitive MET kinase inhibitor. In enzymatic assays, AMG-337(AMG337) inhibits MET kinase activity (IC50: < 5 nM).

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.
