N-(2-hydroxy phenyl) acetamide inhibits inflammation-related cytokines and ROS in adjuvant-induced arthritic (AIA) rats.

The present study was carried out to study the anti-arthritic and anti-inflammatory activity of N-(2-hydroxy phenyl) acetamide in adjuvant-induced arthritis in adult female Sprague Dawley rats. During experimental period, body weight and paw oedema volume were observed. At the end of each experiment, plasma and serum samples were collected and used for estimation of pro-inflammatory cytokines IL-1 beta and TNF-alpha and oxidative stress markers i.e., nitric oxide, peroxide and GSH. Our results suggested that, the reduction in body weight and increase in paw oedema volume were significantly retarded in the AIA rats receiving 5mg/kg and 10mg/kg doses of N-(2-hydroxy phenyl) acetamide as compared to diseased control animals. The serum levels of IL-1 beta and TNF-alpha were reduced as compared to those in the diseased control group. Treatment with N-(2-hydroxy phenyl) acetamide also altered oxidative stress markers in relation to its anti-inflammatory activity. Based on our results, it can be concluded that N-(2-hydroxy phenyl) acetamide possesses promising anti-arthritic property.
