Sorafenib: An Inhibitor of Multiple Protein Kinases

The Ras/Raf/MEK/ERK signaling pathway is an important mediator of tumor cell proliferation and angiogenesis. Sorafenib (BAY 43-9006) inhibits intracellular Raf kinases (C-Raf, B-Raf and mutant B-Raf) and cell surface receptor tyrosine kinases (c-KIT, FLT- 3, RET, VEGFR-1, VEGFR- 2, VEGFR- 3, and PDGFR).1-4) Several of these kinases are thought to be involved in tumor cell signaling, angiogenesis and apoptosis. In fact, sorafenib decreases tumor cell proliferation and angiogenesis in vitro. There are reports, that sorafenib also inhibits LRRK2 (Leucine-rich repeat kinase 2) –G2019S that is a promising therapeutic target for the treatment of Parkinson's disease.5) (The product is for research purpose only.)
