Introduction: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are used in treating pathologic conditions such as fever, pain and inflammation by inhibiting cyclooxygenase and consequently prostaglandin production. Recently , the discovery of different isoforms of this enzyme, Cyclooxygenase-1 (COX-1) andCyclooxygense-2 (COX-2), has led to the synthesis and introduction of novel drugs with select...

As a continuous research for discovery of new COX-2 inhibitors, chemical synthesis, in vitro biological activity and molecular docking study of anew group of 1,4-dihydropyridine (DHP) derivatives were presented. Novel synthesized compounds possessing a COX-2 SO2Me pharmacophore at the para position of C-4 phenyl ring, different hydrophobic groups (R1) at C-2 position and alkoxycarbonyl groups (...

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...

Arthritis refers to different medical conditions associated with disorder of the primary structures that determine joint functions such as bones, cartilage and synovial membranes. Drug discovery and delivery to retard the degeneration of joint tissues are challenging. Current treatments of different arthritis involves administration of ideal non-steroidal anti-inflammatory drugs (NSAIDs) but ar...

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...

the aim of this research was to investigate the cyclooxygenase-2 (cox-2) selective inhibition effect on haloperidol-induced catatonia. in this study, the effect of orally, acutely and sub-chronically administrations of compound 11b [1-(phenyl)-5-(4-methylsulfonylphenyl)-2-ethylthioimidazole] (2, 4 and 8 mg/kg), a newly selective cox-2 inhibitor, was investigated against the haloperidol-induced ...
