Merestinib

개요LY2801653 is an orally bioavailable MET kinase inhibitor (Ki = 2 nM). It also inhibits MST1R, Axl, MNK1/2, FLT3, DDR1, and DDR2 (IC50s = 11, 2, 7, 7, 0.1, and 7 nM, respectively, in a cell-based assay). It inhibits MET autophosphorylation stimulated by hepatocyte growth factor (HGF) in H460 and S114 cells (IC50s = 35.2 and 59.2 nM, respectively) and inhibits growth of Ba/F3 cells transfected with MET-activating mutations (IC50s = 12-248 nM). LY2801653 (0.01-10 μM) completely blocks cell scattering induced by HGF in DU145 cells. It reduces tumor growth in MET autocrine (U-87MG) and MET over-expression (H441) mouse xenograft models when administered at doses of 4 and 12 mg/kg.
