Synthesis and anti-inflammatory activity of some new 4,5-dihydro-1,5-diaryl-1H-pyrazole-3-substituted-heteroazole derivatives
2011
Abstract A series of 4,5-dihydro-1,5-diaryl-1 H -pyrazole-3-substituted-heteroazoles were designed and synthesized in order to obtain new compounds with potential anti-inflammatory activity. The title compounds were screened for in vivo anti-inflammatory activity by using Carrageenan induced rat paw edema method. Diclofenac sodium was used as a standard drug for comparison. Out of the 30 compounds tested, compound 19a , 19b , 25a , 25b exhibited significant anti-inflammatory activity. Selected compounds were also screened for in vitro COX-2 inhibition assay and analgesic activity in the acetic acid induced writhing model.
