Introduction: It has been shown that the extract of Elaeagnus angustifolia can inhibit inflammation and pain induced by formalin in mice and rats. The aim of the present study is to reach evaluations of possible cellular and molecular mechanisms of Elaeagnus angustifolia extract in reducing pain and inflammation through examining the extract ability for inhibition of cyclooxygenase (Cox) type ...
Despite the important role of both cyclooxygenase (COX) isoforms (i.e. COX-1 and COX-2) in maintenance of hypersensitivity following peripheral nerve injury, their role in the development of neuropathic pain is not clear. The present study was undertaken to determine the effect of COX inhibitors to address the potential role of COX isozymes in the development of neuropathic pain in rats after c...
Colorectal cancer is one of the most common cancers in the world. Various factors are involved in the development and progression of this disease. One of these agents is cyclooxygenase-2 (COX-2). COX-2 is a product of the PTGS2 gene and converts free arachidonic acid to prostaglandins. COX-2 is not naturally expressed in most normal cells. Noticeably, the increased expression of COX-2 has been ...
objective: endocannabinoid produce analgesia that is comparable which of opioids. the mechanism of antinociceptive effects of (∆) - 9 tetrahydrocannabinol (thc) is suggested to be through cyclooxygenase (cox) pathway. in the present work, the effect of two extreme dose ranges of celecoxib (mg/kg and ng/kg), a cyclooxygenase-2 (cox-2) antagonist, on arachidonylcyclopropylamide (acpa, a selective...
Two forms of cyclooxygenase are known to be present in eukaryotic organisms: a cyclooxygenase (COX-1) first purified from ram seminal vesicles encoded by a 2.8-kilobase mRNA, and a newly discovered mitogen-inducible cyclooxygenase (COX-2) encoded by a 4-kilobase mRNA. Expression of these two forms of the enzyme in rat alveolar macrophages stimulated with lipopolysaccharide was investigated by 1...
A group of regioisomeric 5-oxo-1,4,5,6,7,8 hexahydroquinoline derivatives possessing a COX-2 SO2Me pharmacophore at the para position of the C-2 or C-4 phenyl ring, in conjunction with a C-4 or C-2 phenyl (4-H) or substituted-phenyl ring (4-F,4-Cl,4-Br,4-OMe,4-Me, 4-NO2), were designed for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors. These target 5-oxo-1,4,5,6,7,8 hexahydroquino...
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...
