The concept was appealing in its simplicity. Traditional nonsteroidal antiinflammatory drugs (NSAIDs) inhibited both isoforms of the enzyme cyclooxygenase responsible for the first step in the conversion of arachidonic acid into a variety of prostaglandins, thromboxanes, and leukotrienes throughout the body. The anti-inflammatory and pain-relieving effects of NSAIDs resulted from inhibition of ...

Cyclooxygenase is known to be the ratelimiting enzyme in the production of prostaglandins. So far, in different bird species there have been found two isoforms of cyclooxygenases (COX), cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2). These isoforms along with prostaglandins are regarded to possess a determining influence on the success in female reproduction. Only in a few bird species t...

Two forms of cyclooxygenase, cyclooxygenase-1 (COX-1) and cyclooxygenase 2 (COX-2), act as rate-limiting enzymes in prostaglandin and thromboxane synthesis. Discovery of these compounds led to the development of drugs that selectively or specifically inhibit the COX-2 isoform. Although the COX-1 isoform is expressed at fairly constant levels in cells, including the gastrointestinal mucosa and p...

BACKGROUND Arachidonic acid metabolite, generated by cyclooxygenase (COX), is implicated in the colorectal cancer (CRC) pathogenesis. Inhibiting COX may therefore have anti-carcinogenic effects. Results from use of non-steroidal anti-inflammatory drugs inhibiting only COX have been conflicting. It has been postulated that this might result from the shunting of arachidonic acid metabolism to the...

Non-steroidal anti-inflammatory drugs (NSAIDs) are used to treat acute and chronic pain associated primarily with inflammatory changes. This group of is widely in neurology, rheumatology, traumatology, etc. The main mechanism action the effect on cyclooxygenase-2 (COX-2) blockade synthesis pro-inflammatory prostaglandins (PG), as well COX-1 suppression cytoprotective PG, which determines possib...

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 ...

Introduction: Kainic Acid (KA) is an ionotropic glutamate receptor agonist. KA can induce neuronal overactivity and excitotoxicity. Rosmarinic Acid (RA) is a natural polyphenolic compound with antioxidant, anti-apoptotic, anti-neurodegenerative, and anti-inflammatory properties. This study aimed to assess the effect of RA on apoptosis, nNOS-positive neurons number, as well as Mitogen-Activated ...

A small set of substituted 1,5-diarylpyrrole-3-acetic and -glyoxylic acid derivatives have been synthesized, and their cyclooxygenase (COX-1 and COX-2) inhibiting properties have been evaluated. Some compounds proved to be highly selective COX-2 inhibitors, and their affinity data have been rationalized through docking simulations in terms of interactions with a crystallographic model of the CO...

Effects of multiple-dose regimens (oral, daily, once a day for 15 days) cyclooxygenase (COX) inhibitors etoricoxib (1 and 10 mg/kg), diclofenac sodium 5 mg/kg) their combinations with 2-ethyl-6-methyl-3-hydroxypyridine succinate (mexidol 25 on rat behavior were studied in the open field test, rotarod test elevated plus maze test. Exploratory (in test) locomotor rats was significantly weakened o...
