Description: Merestinib, also known as LY2801653, is an orally available, small molecule inhibitor of the proto-oncogene c-Met (mesenchymal-epithelial transition, also known as hepatocyte growth factor receptor [HGFR]) with potential antineoplastic activity. c-Met inhibitor LY2801653 selectively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. This may induce cell death in tumor cells overexpressing c-Met protein or expressing constitutively activated c-Met protein. This agent has potent anti-tumor efficacy in mono- and combination therapy in a broad range of cancers.

Additional Information

  LY2801653 was identified and developed as a novel, potent, and orally active small molecule inhibitor of human c-Met. It demonstrated dose dependent inhibition of c-Met phosphorylation in xenograft tumors with a long lasting PD effect.  LY2801653 displayed potent anti-tumor efficacy in a number of non small cell lung, renal, pancreatic, and breast tumor models. Examination of c-Met expression in these tumors by immunohistochemistry (IHC) revealed a good correlation between response and c-Met expression in the tumor tissue.  LY2801653 treatment led to increase in functional vessel areas, and decrease in tumor hypoxia. Enhanced anti-tumor efficacy was achieved when Erlotinib was combined with LY2801653. . (source:
