Cell viability gradually decreased with increasing Sinomenine concentration. The migration ability of MDA-MB-231 cells is significantly weakened by 0.25, 0.5, and 1 mM of Sinomenine treatment. The wound-healing assay reveals that 0.25 and 0.5 mM Sinomenine significantly suppress the healing of the wound. When the MDA-MB-231 cells are treated with 0.5 mM Sinomenine, the healing progress is about 50%, but in the group treated with 0.25 mM Sinomenine and the untreated control, the healing is about 80% and nearly 95%, respectively. The IB assay following inhibitor of NF-κB (IκB) antibody IP shows that the binding of NF-κB to IκB is inhibited by Sinomenine treatment in a dose-dependent manne[1].

Protocol
The MDA-MB-231 human triple negative and 4T1 mouse breast cancer cell lines are used in this study. For the experiments, the cells are grown in 24-well plates at 3.5×104/well. Following incubation for 24 or 48 h in medium containing different concentrations of Sinomenine, proliferation of the cells are detected with Cell Counting Kit-8 solution according to the manufacturer's instructions[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Male Sprague-Dawley rats weighing of 250 to 300 g are used in this experiment. For the duration of action of acute Sinomenine study, different doses of Sinomenine (10 to 40 mg/kg) are administered 1 day after surgery and then paw withdrawal threshold is measured every 30 min for 4 hours. For the study involving daily Sinomenine treatment, mechanical hyperalgesia measure is performed 3 h after daily drug treatment. For antagonist studies, antagonists were given 10 min prior to 40 mg/kg Sinomenine administration[3].
