MET tyrosine kinase inhibitor PF-04217903
An orally bioavailabe, small-molecule tyrosine kinase inhibitor of the proto-oncogene c-Met (hepatocyte growth factor receptor [HGFR]) with potential antineoplastic activity. c-Met inhibitor PF-04217903 selectively binds to and inhibits c-Met, disrupting the c-Met signaling pathway, which may result in the inhibition of tumor cell growth, migration and invasion of tumor cells, and the induction of death in tumor cells expressing c-Met. 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)
