Sorafenib tosylate, also named nexavar, is a small-molecule anticancer compound [1]. It is also a novel oral Raf kinase and a vascular endothelial growth factor receptor (VEGFR) inhibitor. It inhibits tumor cell proliferation and tumor angiogenesis [2]. To HepG2 cells (1× 106), the IC50 of sorafenib tosylate is 2.09μg/ml [3].
Raf is a mitogen-stimulated protein kinase that functions as a component of the signaling cascade that leads to the stimulation of mitogen-activated protein kinase [4].
Vascular endothelial growth factor (VEGF) is a highly specific mitogen for vascular endothelial cells [5].
Treatment with nexavar potently inhibited the cell proliferation of MV4-11 cells (FLT3-ITD) in a dose-dependent manner with an IC50 of 0.88 nM. In MV4-11 cells, sorafenib tosylate of a concentration of 100 nM induced 43.6±5.2% of the cells to undergo apoptosis whereas in EOL-1 cells a concentration as low as 10 nM induced 89.29±1.8% of the cells to be apoptotic [6].
Nude rats at the age of 6 weeks injected with 105 MDA-MB-231 cells were involved. After monotherapy with sorafenib tosylate a significant reduction of the osteolytic lesion volume was observed on days 45 and 55 and of the soft tissue component volume on day 55 in comparison to untreated animals (p < 0.05). Compared to controls, treatment with sorafenib tosylate made bone metastases show significantly decreased values of Amplitude A and kep from day 35 to 55 (Amplitude A: p<0.01; kep p<0.01 on days 35 and 55; p<0.05 on day 45) [7].
