function and application:
sorafenib is a raf kinase inhibitor which suppresses erk phosphorylation. studies indicate that sorafenib induces c-raf phosphorylation
at both ser-43 and ser-259. when combined with vitamin k1 phosphorylation is increased at these serine residues. sorafenib also induces the phosphorylation of pka. in addition, sorafenib induces c-met phosphorylation at tyr-1349, which consequently induces pi3k-akt phosphorylation. studies determined that sorafenib inhibits other kinases such as flk-1 (vegfr2), platelet-derived growth factor receptor (pdgfr), flt3, ret, and c-kit.
