Schisandrin B (Sch B) is the most abundant, active dibenzocyclooctadiene derivative isolated from the fruit of Schisandra chinensis (Turcz) Baillon (Schisandraceae). (-)Sch B was found to be the most potent stereoisomer of Sch B in producing cytoprotective action in H9c2 cardiomyocytes. The elucidation of biochemical mechanism underlying the cytoprotection of (-)Sch B has attracted much interest in the area of preventive medicine. Here, we examined whether the (-)Sch B-induced enhancement of glutathione antioxidant and heat shock responses and the associated cytoprotection against hypoxia/reoxygenation-induced apoptosis are mediated by reactive oxygen species (ROS) arising from cytochrome P-450 (CYP)-catalyzed metabolism of (-)Sch B in H9c2 cardiomyocytes.
