title: New celecoxib derivatives as anti-inflammatory agents.
abstract: A series of 1,5-diarylpyrazoles with a substituted benzenesulfonamide moiety was synthesized and evaluated for cyclooxygenase (COX-1/COX-2) inhibitory activities. Some compounds, for example, (+/-)-2-[4-(5- p-tolyl-3-trifluoromethyl-pyrazole-1-yl)-benzenesulfonylaminooxy]-propionic acid 16 and its disodium salt 21, had a higher in vivo anti-inflammatory activity compared to celecoxib, despite having no in vitro COX-1 or COX-2 inhibitory activity. Their gastrointestinal side effect profile is essentially more favorable than that of celecoxib.
