Sorafenib (Bay 43-9006) tosylate is a potent oral active multikinase inhibitor. Sorafenib blocks autophosphorylation and activity of receptor tyrosine kinases (VEGFR-2, VEGFR-3) and RAF family kinases, thereby suppressing the RAF/MEK/ERK and PI3K/Akt pathways, inhibiting STAT3 phosphorylation, and selectively inhibiting the MAPK pathway in cancer cells. Sorafenib tosylate induces cell cycle arrest, autophagy, apoptosis, and PARP cleavage, reduces Bcl-2, Bcl-XL, cyclin D1 levels, and activates Bak and Bax. Sorafenib tosylate inhibits tumor growth and metastasis in mouse and rat models. Sorafenib tosylate can be used for cancer research, such as colon, breast, non-small-cell lung cancer (NSCLC), ovarian, pancreatic, melanoma, colorectal and hepatocellular carcinoma[1][2][3][4][5][6].
