Chemical Structure

Biological activities

LY2801653 is a type-II ATP competitive, slow-off inhibitor of MET tyrosine kinase. The Ki value of LY2801653 for MET is 2 nM. The Koff and t1/2 of LY2801653 is 0.00132 minutes-1 and 8.75 hours, respectively. The IC50 value o f LY2801653 for inhibition of MET auto-phosphorylation in HGF-stimulated H460 cells is 35.2 nM. The IC50 value o f LY2801653 for inhibition of MET auto-phosphorylation in S114 cells is 59.2 nM. In vitro, LY2801653 also potently blocks HGF-induced DU-145 cell scattering. LY2801653 has more potent anti-proliferative activity in cell lines with MET gene amplification (MKN45, Hs746T and H1993) than the cell lines without MET gene amplification (U-87MG, KATO-III). In S114 xenograft model in vivo, LY2801653 treatment inhibits MET phosphorylation with a composite TED 50 (50 % target inhibition dose) of 1.2 mg/kg and a composite TED 90 (90 % target inhibition dose) of 7.4 mg/kg. In mouse xenograft models (including U-87MG, MKN45, H1993, H441, and HT29 models), LY2801653 treatment (12 mg/kg) shows significant anti-tumor activities.[1]
