Sorafenib is an oral multikinase inhibitor with activity against Raf kinase and several receptor tyrosine kinases, including vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor (PDGFR), FLT3, Ret, and c-Kit. sorafenib, inhibits tumor growth and disrupts tumor microvasculature through antiproliferative, antiangiogenic, and/or proapoptotic effects. sorafenib blocks Raf kinase signaling, inhibits tumor cell proliferation, and induces apoptosis in vitro. In addition, sorafenib exhibits robust antitumor efficacy.

General tips
We do not recommend long-term storage for the solution, please use it up soon.
Protocol
Cell experiment: [1]
Cell lines
PLC/PRF/5 and HepG2 cells
Preparation method
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.
Reaction Conditions
IC50: 6.3 μM for PLC/PRF/5 cells 4.5 μM for HepG2 cells 72 hours
Applications
The effect of sorafenib on cell proliferation was measured by CellTiter-Glo assay. Sorafenib inhibited cell proliferation dose-dependently with an IC50 of 6.3 μmol/L in PLC/PRF/5 and 4.5 μmol/L in HepG2 cells.
Animal experiment: [1]
Animal models
Female CB17 SCID mice injected with PLC/PRF/5 cells
Dosage form
Oral administration; 10, 30, and 100 mg/kg body weight; once daily for 16 or 21 days
Applications
Sorafenib tosylate produced dose-dependent growth inhibition of s.c. implanted PLC/PRF/5 tumor xenografts in SCID mice. Dose levels of 10 and 30 mg/kg produced significant and dose-dependent TGIs of 49% and 78%, respectively. Sorafenib tosylate produced durable partial tumor regressions in 50% of the mice at the 100 mg/kg dose level.
Other notes
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
