چکیده انگلیسی
Osteoarthritis (OA) is the most prevalent disease of knee especially in the aged people. Isofraxidin (IF) is a coumarin compound refined from traditional Chinese medicines with potential anti-inflammatory ability. This study aimed to evaluate protective anti-inflammatory effects of IF in human OA chondrocytes. The chondrocytes were isolated from OA patients and pretreated with IF before treatment with IL-1β. The results showed that IF blocked IL-1β-stimulated production of NO and PGE2. In addition, IF inhibited the expression of COX-2, iNOs, MMP-1, MMP-3, MMP-13, ADAMTS-4 and ADAMTS-5, and increased the levels of aggrecan and collagen-II. Mechanistically, IF suppressed IL-1β-induced IκB-α degradation and NF-κB activation. In conclusion, our results demonstrate that IF inhibits inflammation in OA via the regulation of NF-κB signaling, and suggest that IF may be a potential therapeutic agent for OA.
