New Celecoxib Derivatives as Anti-Inflammatory Agents
摘要:
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.

for the conversion of glycerol to allyl alcohol, where ammonia or organic acids are added to the feed as sacrificial reductants, was investigated. Significant enhancement on the rate of formation and yield of the allyl alcohol is observed with some of the reducing agents examined over an alumina-supported iron catalyst. Optimising the molar ratio of the reductant relative to feed glycerol results in an
