and COX-3Classic NSAIDsSelective 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 iso...
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...

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 ...
实际上,人体内具有两种环氧酶,即COX-1和COX-2,我们可以这么理解:COX-1负责产生“维持机体正常生理过程所需的前列腺素类物质或血栓素等”,从而对胃粘膜、血管、血小板、肾脏血流灌注等起到良性促进作用。所以,COX-1是一种“内务酶(housekeeping enzyme)”,它的存在对机体的正常生理功能的维持是正向作用,而不具有副...

The main adverse reactions of selective COX-2 inhibitors are gastrointestinal ulcers, perforation or bleeding, damage to renal function, coagulation disorders and thrombosis. The factors associated with the mechanisms are as follows: the COX-2 inhibitors inhibit both COX-1 and COX-2 at the same ...

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...
