Schizandrin

Schizandrin is a dibenzocyclooctadiene lignan and a major component of S. chinensis and has diverse biological activities. It induces cell cycle arrest at the G0/G1 phase and inhibits growth of T47D and MDA-MB-231 breast cancer cells when used at a concentration of 100 µM. Schizandrin (10 and 100 µM) prevents glutamate-induced cytotoxicity, inhibits production of nitric oxide (NO) and reactive oxygen species (ROS), and preserves the mitochondrial membrane potential in isolated rat cortical cells. It reduces apoptosis induced by cisplatin (Cay-13119) in HK-2 human kidney cells. In vivo, schizandrin (1 and 10 mg/kg, p.o.) reverses scopolamine-induced impairment of spatial memory and the passive avoidance response in rats. It enhances oxotremorine-induced tremors in mice. Schizandrin (10 mg/kg) reduces serum levels of IgE, IgG1, IL-4, and IFN-gamma in an ovalbumin-sensitized mouse model of allergy.Formal Name: (6S,7S,12aR)-5,6,7,8-tetrahydro-1,2,3,10,11,12-hexamethoxy-6,7-dimethyl-dibenzo[a,c]cycloocten-6-ol.
