Sorafenib Tosylate (CAS: 475207-59-1) is a new type of multi-target antitumor drug, was developed by the German Bayer Pharmaceuticals, and displayed expansive antitumor activity in preclinical animal tests. Sorafenib is available in 200-mg tablets for oral administrationand is used in the treatment of RCC and HCC. Sorafenib Tosylate (CAS: 475207-59-1) can simultaneously affect tumor cells and tumor blood vessels. It has a double antitumor effect: it can block the cell signal transduction pathways mediated by RAF/MEK/ERK to directly inhibit tumor cell growth, while also inhibiting VEGF and platelet derived growth factors (PDGF) receptors to prevent the formation of new tumor blood vessels, thus indirectly inhibiting tumor cell growth. Sorafenib is an inhibitor of Raf-1 and B-RAF as well as several tyrosine kinases.
