Cyclooxygenase-2 (COX-2) Inhibition Constrains
Indoleamine 2,3-dioxygenase 1 (IDO1) metabolizes L-tryptophan to kynurenines (KYN), inducing T-cell suppression either directly or by altering antigen-presenting-cell function. Cyclooxygenase (COX)-2, the rate-limiting enzyme in the synthesis of prostaglandins, is over-expressed by several tumours. We aimed at determining whether COX-2 inhibitors down-regulate the IFN--induced expression of ID...
متن کاملCOX-2 inhibitors.
Cyclooxygenase-2 (COX-2) inhibitors constitute a new group of non-steroidal anti-inflammatory drugs (NSAIDs) which, at recommended doses, block prostaglandin production by cyclooxygenase-2, but not by cyclooxygenase-1. Two COX-2 inhibitors are currently available in Australia--celecoxib, which is taken twice daily, and rofecoxib, which is taken once daily. Both drugs act rapidly in providing pa...
متن کاملCOX-1 and COX-2 products in the gut: therapeutic impact of COX-2 inhibitors.
Despite the considerable range of newly identified disease modifying approaches to the control of the inflammatory process reported over the past 10–20 years, only a few have yet gained widespread clinical acceptance. In contrast, the very recent advent of the class of anti-inflammatory agents termed COX-2 selective inhibitors is already having a significant impact on current clinical prescribi...
متن کاملGastrointestinal tolerability of the selective cyclooxygenase-2 (COX-2) inhibitor rofecoxib compared with nonselective COX-1 and COX-2 inhibitors in osteoarthritis.
BACKGROUND Most nonsteroidal anti-inflammatory drugs (NSAIDs) are nonselective cyclooxygenase (COX-1 and COX-2) inhibitors and are associated with a variety of upper gastrointestinal (GI) tract symptoms. The roles of COX-1 and COX-2 in the pathogenesis of these symptoms are unclear. To test whether COX-2 inhibition with rofecoxib would have greater GI tolerability than nonselective COX-1 and CO...
