Abstract:
The antioxidant activities of SMND309 were investigated using different analysises including 1, 1diphenyl2picrylhydrazyl (DPPH·) and hydroxyl (·OH) radical scavenging and reducing power, as well as Fe2+ascorbic acid (Vc) system used to cause oxidative damage of the rat liver mitochondria. The effects of SMND309 on mitochondria permeability transition, protein carbonyl group levels and the activity of ATPase were detected.The results demonstrated that SMND309 has a significant reduction capability and a remarkable potency to scavenge DPPH· and hydroxyl (·OH) radical. Furthermore, SMND309 can play a significant role in inhibiting mitochondria permeability transition, the increase of protein carbonyl levels and the decrease of the activity of ATPase. Based on these resules, SMND309 can be used as an effective antioxidant.
