Pharmacogenomics of Cyclooxygenases
Pharmacogenomics, 2015Cyclooxygenases (COX-1 and COX-2) are key enzymes in several physiopathological processes. Many adverse drugs reactions to NSAIDs are attributable to COX-inhibition. The genes coding for these enzymes (PTGS1 and PTGS2) are highly variable, and variations in these genes may underlie the risk of developing, or the clinical evolution of, several diseases ...

Current Opinion in Internal Medicine, 2006
The purpose of this review is to summarize new information regarding the use of selective inhibitors of the cyclooxygenase-2 enzyme, emphasizing recent developments regarding cardiovascular risk.Selective cyclooxygenase-2 inhibitors are as effective as nonselective nonsteroidal antiinflammatory drugs in relieving pain and inflammation but are ...

The anti-inflammatory activity of drugs more selective for cyclooxgenase isoform inhibition (cyclooxygenase 1, cyclooxygenase 2), were compared in rat carrageenin-induced pleurisy. Suppression of inflammation by cyclooxygenase 2-selective inhibitors, NS-398 (N-[-2-cyclohexyloxy]-4-nitrophenyl methanesulphonamide) and nimesulide (4-nitro-2-phenoxy ...

Cyclooxygenase and Colon Cancer
Prostaglandins & Other Lipid Mediators, 2001There is considerable interest in the involvement of cyclooxygenase-2 (COX-2) in colon carcinogenesis and its progression, because nonsteroidal anti-inflammatory drugs (NSAIDs) reduce mortality from colon cancer and COX-2 is one of the known targets of NSAIDs. COX-2 mRNA and protein levels are increased in colon cancer tissues from patients and in some

Publisher Summary This chapter deals with aspects of the discovery and development of Cyclooxygenase-2 (Cox-2) inhibitors, which, in the case of rofecoxib, resulted from efforts that were initiated in July of 1992 and culminated in the launch of the drug in the United States in June of 1999. Nonsteroidal antiinflammatory drugs (NSAIDs) have long been

TWO ISOFORMS: There are two isoforms of cyclooxygenase (COX) with similar structure and metabolic activity. COX-1 is a constitutional enzyme. COX-2 is an inductible form. CYCLOOXYGENASE-1: COX-1 is present in most tissues, particularly in the kidney, the digestive tract mucosa, platelets, brain, liver and spleen.

Perspectives on the Cyclooxygenase-2/ Cyclooxygenase-1 Hypothesis
JCR: Journal of Clinical Rheumatology, 1998The introduction of the cyclooxygenase (COX) hypothesis to explain both the therapeutic effects and the toxicity of nonsteroidal anti-inflammatory drugs (NSAIDs) has provided direction for the development of preferential and highly selective COX-2 inhibitors, which retain efficacy against inflammation with reduced risk of toxicity. However, the complex

Cloning and Expression of Cyclooxygenase-1 and Cyclooxygenase-2
2010Cyclooxygenase (COX) enzymes play important roles in normal physiology and during inflammation of various cells and tissues. In order to help understand the functions of these enzymes, their genes can be cloned to facilitate the production of the proteins in recombinant form.

Current Pharmaceutical Design, 2003
In mammalian cells, eicosanoid biosynthesis is usually initiated by the activation of phospholipase A(2) and the release of arachidonic acid from membrane phospholipids in response to the interaction of a stimulus with a receptor on the cell surface. Arachidonic acid is subsequently transformed by the enzyme cyclooxygenase (COX) to prostaglandins (PGs)
