English Abstract
ABSTRACT :
The development of new COX-2 inhibitors with analgesic and anti-inflammatory efficacy as well as minimal
gastrointestinal, renal and cardiovascular toxicity, is of vital importance to patients suffering from chronic course
pain and inflammatory conditions. This study aims at evaluating the therapeutic activity and adverse drug reactions associated with the use of the newly synthesized pyrazole derivative, compound AD732, E-4-[3-(4-
methylphenyl)-5-hydroxyliminomethyl-1H-pyrazol-1-yl]benzenesulfonamide, as compared to indomethacin and
celecoxib as standard agents. Anti-inflammatory activity was assessed using carrageenan-induced rat paw edema
and cotton pellet granuloma tests; formalin-induced hyperalgesia and hot plate tests were done to study analgesic
activity. In vitro tests to determine COX-1/COX-2 selectivity and assessment of renal and gastric toxicity upon
acute exposure to AD732 were also conducted. Compound AD732 exhibited promising results; higher antiinflammatory and analgesic effects compared to standard agents, coupled with the absence of ulcerogenic effects and minimal detrimental effects on renal function. Additionally, compound AD732 was a less potent inhibitor of COX-2 in vitro than celecoxib, which may indicate lower potential cardiovascular toxicity. It may be
concluded that compound AD732 appears to be a safer and more effective molecule with promising potential for
the management of pain and inflammation.
