The effectiveness of curcumin in preventing and treating collagen-induced inflammatory arthritis (CIA) in rats and oxidative stress in rats was investigated. We investigated curcumin's curative and preventive effects on paw edema, arthritic size, body weight, and radiologic and histological joint abnormalities. It has been shown that curcumin may dramatically lower the risk of developing arthritis. In addition, the number of white blood cells (WBCs) in the body has dropped, which is a strong indication that curcumin has anti-inflammatory characteristics. A follow-up theoretical investigation of curcumin molecular docking on xanthine oxidase (XO) was carried out after the properties of curcumin were determined using the conductor-like screening model for real solvents (COSMO-RS) theory. Because of the interaction between curcumin and the residues on XO named Ile264, Val259, Asn351, and Leu404, XO may be suppressed by this molecule. Curcumin's anti-inflammatory and antioxidant properties may be responsible for the anti-arthritic effects that have been seen on oxidative stress markers and XO. On the other hand, more research is being conducted to understand its function better in the early stages of rheumatoid arthritis (RA). To determine whether or not curcumin interacts with AR targets, a molecular docking study was conducted using MVD software against TNFRSF11A and cathepsin L.
