Structure activity relationship studies of synthesised pyrazolone derivatives of imidazole, benzimidazole and benztriazole moiety for anti-inflammatory activity. Journal of Applied Pharmaceutical Science. 2011 Jun; 1(4): 115-120.http://imsear.searo.who.int/handle/123456789/150797In the present investigation, a series of some synthesis and biological evaluation of some pyrazolone derivatives with imidazole, benzimidazole and benztriazole moiety were synthesized and tested for their anti-inflammatory activity in-vitro using celecoxib as a reference drug. Compound 8d was found to be the most potent derivative of the series with 75 %inhibition of inflammation.enPyrazoloneimidazolebenzimidazolebenztriazole%inhibition of inflammationArticle
