NCIt synonyms : BAY 73-4506; 4-(4-(((4-chloro-3-(trifluoromethyl)phenyl)carbamoyl)amino)-3-fluorophenoxy)-N-methylpyridine-2-carboxamide; Multitargeted Receptor Tyrosine Kinase Inhibitor BAY 73-4506;
NCIt related terms : Regorafenib;
NCIt definition : The anhydrous form of regorafenib, an orally bioavailable small molecule with potential
antiangiogenic and antineoplastic activities. Regorafenib binds to and inhibits vascular
endothelial growth factor receptors (VEGFRs) 2 and 3, and Ret, Kit, PDGFR and Raf
kinases, which may result in the inhibition of tumor angiogenesis and tumor cell proliferation.
VEGFRs are receptor tyrosine kinases that play important roles in tumor angiogenesis;
the receptor tyrosine kinases RET, KIT, and PDGFR, and the serine/threonine-specific
Raf kinase are involved in tumor cell signaling.;
