Sorafenib is an oral multikinase inhibitor with activity against Raf kinase and several receptor tyrosine kinases, including vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor (PDGFR), FLT3, Ret, and c-Kit. sorafenib, inhibits tumor growth and disrupts tumor microvasculature through antiproliferative, antiangiogenic, and/or proapoptotic effects. sorafenib blocks Raf kinase signaling, inhibits tumor cell proliferation, and induces apoptosis in vitro. In addition, sorafenib exhibits robust antitumor efficacy.
