描述 | Schizandrin is a major bioactive constituent of Schisandra chinensis (Turcz.) Baill with antioxidant and anti-inflammatory properties. Schizandrin prevented LPS-induced injury in the H9c2 cells and promoted the recovery of myocardial tissues by enhancing cell viability and migration[3]. Sch A specifically reverses P-gp-mediated DOX resistance in MCF-7/DOX cells by blocking P-gp, NF-κB, and Stat3 signaling. Inhibition of P65 and Stat3 shows potent anti-MDR (Multidrug resistance) effect on MCF-7/DOX cells[4]. Schizandrin (1 and 10 mg/kg, p.o.) significantly reversed the scopolamine-induced impairment of spatial memory. Similarly, schizandrin (1 mg/kg, p.o.) significantly reversed the scopolamine-induced impairment of the passive avoidance response. Moreover, in mice, schizandrin (1 and 10 mg/kg, p.o.) enhanced tremors induced by oxotremorine, a muscarinic M(1) receptor agonist[5]. Pretreatment of the cortical cell cultures with schizandrin (10, 100 microM) for 2 h significantly protected cortical neurons against Glu-induced excitotoxicity. The neuroprotective activity of schizandrin was the most potent at the concentration of 100 microM. In addition, schizandrin diminished the intracellular Ca2+ influx, inhibited the subsequent overproduction of nitric oxide (NO), reactive oxygen species (ROS), and cytochrome c, and preserved the mitochondrial membrane potential. Furthermore, schizandrin also increased the cellular level of glutathione (GSH) and inhibited the membrane lipid peroxidation malondialdehyde (MDA)[6]. Schizandrin can be used to treat inflammatory and atopic diseases through the inhibition of TSLP(Thymic stromal lymphopoietin) [7]. |
