Selective COX-2 inhibitorsCOX-3 inhibitorsProstaglandins are formed from arachidonic acid by the action of cyclooxygenase and subsequent downstream synthetases. Two closelyrelated forms of the cyclooxygenase have been identified which are now known as COX-1 and COX-2. Both isoenzymes transformarachidonic...

——关于“选择性COX-2抑制药(cyclooxygenase-2 selective inhibitors)”: 总说:我们前面已经讲了,对于非选择性的NSAIDs,其解热镇痛抗炎抗风湿的药理效果主要是由于抑制了COX2所产生的,而各种副作用主要是由于抑制了COX-1所产生的。所以,如果我们设计出“只能够抑制COX-2而不一致COX-1的药物”,就可以很大程度上...
The recognition that there are two cyclo-oxygenase enzymes, one predominating at sites of inflammation (COX-2) and one constitutively expressed in the gastrointestinal tract (COX-1), has led to the important therapeutic development of COX-2 inhibitors. COX-2 is phylogenetically more primitive that...

Can both cyclooxygenase-1 (COX-1) and COX-2 medications be combined for patients with osteoarthritis (OA) pain not relieved by high doses of either group alone? What would be a recommended starting combination and doses?
所以可以说COX2的抑制剂是直接作用于AS这个疾病本身的,并且可以说抑制炎症就是保护关键,同时抑制炎症也是缓解疼痛,所以说很多人就简单的把AS里用的COX2抑制剂认为是“止痛药”!!!然而由于人体中有两种COX酶,一种是COX1,一种是COX2,COX1和炎症无关它的主要作用是保护消化道黏膜,而COX2是和炎症有关但是不保护...

This paper focuses on the synthesis and the in vitro testing of dual COX-1/COX-2 inhibitors. Starting from structures of non-steroidal anti-inflammatory drugs (NSAIDs) the diaryl methanone element was chosen as a lead. Modifications were carried out on this scaffold to obtain potent inhibitors...
However, further experimental and clinical studies will be necessary, mainly with regard to new untypical side effects to show whether or not selective COX-2 inhibitors are of clinical value in the treatment of rheumatic disorders. 展开 关键词: chylous tenosynovitis Mycobacteria kansasii ...
