Chemical Structure

Biological activities

MK-8033 is a dual c-Met/Ron inhibitor. The IC50s against c-Met and Ron are 1 and 7 nM, respectively. In a BIAcore-based direct binding assay, MK-8033 binds 3-fold more tightly to phosphorylated c-Met kinase domain (Kd= 3.2 nM) than to its unphosphorylated counterpart (Kd= 10.4 nM). MK-8033 is a weak inhibitor of cytochrome P450s at high μM concentrations. In vitro, MK-8033 inhibits the growth of GTL-16 with an IC50 of 580 nM. MK-8033 also potently inhibits c-Met/HGF-dependent cellular phenotypes in vitro. In human GTL-16 cMet amplified gastric tumor xenografts in CD1-nude mice, MK-8033 (100 mg/kg) achieves significant tumor inhibition in vivo.[1]
