Abstract

Physalin A (PA), a withanolide, was isolated from Physalis angulata L. In this study, it is shown that PA can inhibit the production of inflammatory cytokines such as PGE₂, NO, IL-1β, IL-6, and TNF-α in LPS-induced RAW 264.7 cells. Furthermore, the results indicated that PA suppressed the IκB/NF-κB and JNK/ AP-1 inflammatory signaling pathways and inhibited the levels of pro-inflammatory factors iNOS and COX-2 in LPS-stimulated RAW 264.7 cells. In the carrageenan-induced mouse hind paw edema study, PA was shown to inhibit the production of inflammatory mediators such as NO, MDA, and TNF-α production. Conversely, the antioxidant factor levels of SOD, CAT, and GPx were all increased by the treated PA. According to the data, we are suggesting that the anti-inflammatory effects of PA may be through the suppressions of the JNK/AP-1 and IκB/NF-κB signaling pathways and up-regulation of the anti-oxidative activity.
