Nimesulide (Biphenyl Ether) derivatives were synthesized by four steps, Step-1-Ulmaan ether synthesis, Step-2-Reduction of NO2, Step-3-Condensation reaction, Step-4-Nitration and evaluated for their anti-inflammatory and analgesic activities.
The compounds have been characterized on the basis of preliminary methods, spectral data and tested for anti-inflammatory activity and compared with standard drug as per the standard drug rat hind paw edema method by using Plethesimograph and analgesic activity by Eddies-hotplate method. Among the derivatives prepared, few showed the moderate activity and few showed decreased activity.

Abstract


Nimesulide (Biphenyl Ether) derivatives were synthesized by four steps, Step-1-Ulmaan ether synthesis, Step-2-Reduction of NO2, Step-3-Condensation reaction, Step-4-Nitration and evaluated for their anti-inflammatory and analgesic activities.
The compounds have been characterized on the basis of preliminary methods, spectral data and tested for anti-inflammatory activity and compared with standard drug as per the standard drug rat hind paw edema method by using Plethesimograph and analgesic activity by Eddies-hotplate method. Among the derivatives prepared, few showed the moderate activity and few showed decreased activity.
