  LY2801653 (Merestinib)


Description of LY2801653: LY2801653, also known as Merestinib,  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. c-Met, a receptor tyrosine kinase overexpressed or mutated in many tumor cell types, plays key roles in tumor cell proliferation, survival, invasion, metastasis, and tumor angiogenesis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus). (last updated: 5/2/2015).

Information about this agent

 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:

LY2801653 is an orally bioavailable multi-kinase inhibitor with potent activity against MET, MST1R, and  other oncoproteins, and displays anti-tumor activities in mouse xenograft models.
