NCIt definition : An orally bioavailable small molecule with potential antineoplastic activity. CHIR-265
binds and inhibits Raf kinases, which may result in a reduction of tumor cell growth
and proliferation, and tumor cell death. In addition, this agent inhibits vascular
endothelial growth factor receptor type 2 (VEGFR-2), thereby disrupting tumor angiogenesis.
Raf kinases are critical enzymes in the Ras/Raf/MEK/ERK signaling pathway and are
frequently upregulated in neoplasms.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of melanoma. CHIR-265 may block
the growth of tumors and the growth of blood vessels from surrounding tissue to the
tumor. It is a type of Raf kinase inhibitor and angiogenesis inhibitor.;
