PF-04217903 is a triazolopyrazine inhibitor of c-MET that displays anticancer chemotherapeutic and anti-metastatic activities. PF-04217903 inhibits cell proliferation, invasion, and migration as well as tumor growth in various cancer models. In animal models of pancreatic neuroendocrine tumors, this compound prevents lymph node metastasis. PF-04217903 had been in phase I clinical trials by Pfizer for the treatment of solid tumors. In 2011, the company discontinued the development of the compound.
