cyclooxygenase-2 (cox-2) has a pivotal role in the pathogenesis of the lung cancer. it is known that cox-2 negatively regulates the activity of a number of tumor suppressors, including p53. consequently, inhibition of cox-2 signaling is anticipated to be a promising approach to stabilize p53 functionality. in this regard, we investigated the effect of cox-2 signaling blockade on p53 and cox-2 e...
Non-steroidal anti-inflammatory drugs (NSAIDs) are the competitive inhibitors of cyclooxygenase (COX), the enzyme which mediates the bioconversion of arachidonic acid to inflammatory prostaglandins (PGs). Their use is associated with the side effects such as gastrointestinal and renal toxicity. The therapeutic anti-inflammatory action of NSAIDs is produced by the inhibition of COX-2, while the ...

A new group of 4-(Imidazolylmethyl) quinoline derivatives possessing a methylsulfonyl COX-2 pharmacophore at the para position of the C-2 phenyl ring were designed and synthesized as selective COX-2 inhibitors and in-vitro anti breast cancer agents. In-vitro COX-1 and COX-2 inhibition studies showed that all the compounds were potent and selective inhibitors of the COX-2 isozyme with IC50 value...
Cyclooxygenase (COX) is the key enzyme required for the conversion of arachidonic acid to prostaglandins. Two cycloxygenase isoforms have been identified and are referred to as COX-1 and COX-2. Both enzymes are blocked by nonselective anti-inflammatory drugs (NSAID), such as indomethacin and ibuprofen. COX-1 is an enzyme normally found in tissues and is involved in physiological functions, whil...
