Treatment of rheumatoid arthritis with curcumin analog 3,5-bis(arylidene)-4-piperidone

Rheumatoid arthritis (RA) is an inflammatory disease. Curcumin can inhibit NF-kappa B and reduce the expression of inflammation-related genes. Aim: To evaluate the potential development of 6d in the clinical treatment of inflammatory diseases such as RA. Methods: Using a skeleton fusion strategy to synthesize curcumin analogues for 6d. This work evaluates anti-inflammatory activity by conducting anti-arthritis experiments (adjuvant-induced RA models) on rats. Western blot and Elisa were used to detect the expression of inflammatory-related proteins and cytokines. Molecular docking analysis confirmed the binding effect of 6d with active sites. Conclusion:6d inhibits NF-kappa B has a protective effect on arthritis caused by RA.
