Description: Semaxanib, also known as SU5416, is a quinolone derivative with potential antineoplastic activity. Semaxanib reversibly inhibits ATP binding to the tyrosine kinase domain of vascular endothelial growth factor receptor 2 (VEGFR2), which may inhibit VEGF-stimulated endothelial cell migration and proliferation and reduce the tumor microvasculature. This agent also inhibits the phosphorylation of the stem cell factor receptor tyrosine kinase c-kit, often expressed in acute myelogenous leukemia cells.

Semaxanib (SU5416) is a tyrosine-kinase inhibitor drug designed by SUGEN as a cancer therapeutic. It is an experimental stage drug, not licensed for use on human patients outside of clinical trials. Semaxanib is a potent and selective synthetic inhibitor of the Flk-1/KDR vascular endothelial growth factor (VEGF) receptor tyrosine kinase. It targets the VEGF pathway, and both in vivo and in vitro studies have demonstrated antiangiogenic potential. On February 2002, Pharmacia, the then parent of Sugen, prematurely ended Phase III clinical trials of Semaxinib in the treatment of advanced colorectal cancer due to discouraging results. Other studies, at earlier phases, have since been conducted. However, due to the prospect of next-generation tyrosine kinase inhibitors and the ineffaciousness of semaxanib in clinic trials, further development of the drug has been discontinued. A related compound, SU11248 was further developed by Sugen, and then by Pfizer and was FDA-approved as Sunitinib (Sutent) for treatment of renal carcinoma in January 2006.
