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...

A new series of peptide-like derivatives containing different aromatic amino acids andpossessing pharmacophores of COX-2 inhibitors as SO2Me or N3 attached to the para positionof an end phenyl ring was synthesized for evaluation as selective cyclooxygenase-2 (COX-2)inhibitors. The synthetic reactions were based on the solid phase peptide synthesis methodusing Wang resin. One of the analogues, i...

Introduction: Migraine is a common debilitating headache with reversible pain attacks associated with temporal changes in the diameter of head blood vessels. According to the International Classification for the Headache Society, migraineurs are divided into two main categories: migraine with aura and migraine without aura. The present study aimed to investigate the association between COX-2-7...

A group of 1,3-biarylhydrazide derivatives possessing a COX-2 azido pharmacophore at the Para- position of the C-1 phenyl ring in conjunction with a N-3 phenyl or substituted-phenyl ring (4-F,4-Cl,4-OMe) were designed and synthesized based on nucleophilic substitution reaction. A molecular modelling study of these compounds showed that the designed molecules were well bound with the active site...

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 ...

background: lymphomas are a group of malignancies affecting b, t and nk cells. cox-2 enzyme is one of the known inflammatory factors which increase in the inflammation process. increase in cox-2 expression inhibits apoptosis and increases tumor cells invasion and angiogenesis. increase in the cox-2 gene expression is seen in a group of cancers .specific cox-2 inhibition also can be beneficial i...
