Description and Uses

Sorafenib (475207-59-1) was initially developed as a Raf kinase inhibitor, IC50 = 6 nM, but has been shown to inhibit many receptor tyrosine kinases including BRAF (IC50 = 22 nM); VEGFR-2 (IC50 = 90 nM); VEGFR-3 (IC50 = 20 nM); PDGFR-β (IC50 = 57 nM); Flt3 (IC50 = 58 nM); c-KIT (IC50 = 68 nM); FGFR-1 (IC50 = 580 nM).1?Paradoxically more potent in a cellular assay (IC50 = 20 nM) compared to an isolated enzyme assay (IC50 = 107 nM) for c-Fms.2?Inhibits activation of MAPK pathway and ERK phosphorylation.3?Induces caspase-independent apoptosis in melanoma cells.4?Sorafenib is a clinically useful anticancer agent.

Sorafenib Tosylate (Bay 43-9006, Nexavar) is a small molecular inhibitor of VEGFR, PDGFR, c-Raf and B-Raf with IC50s of 18 nM, 10 nM, 3 nM and 15 nM, respectively.
