COX-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 acid to prostaglandins, ...
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...
On the other hand the inducible COX-2 is responsible for pathophysiological processes such as inflammation. These differences between both isozymes may lead to the development of selective COX-2 inhibitors with less renal and gastrointestinal side effects. Numerous in vitro studies have shown that ...

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...
Thus, the initial component of thermal hyperalgesia after tissue injury was blocked by systemic or spinal administration of both COX inhibitors, whereas established hyperalgesia was reversed only by systemic inhibitors. This study demonstrates that at least spinal COX-2, if not both COX-1 and COX-...

However, non-selective inhibition by selective COX-1 and COX-2 inhibitors of brain PGE2 generation upon zymosan injection does not support the role of COX-2 expressed in brain in zymosan-induced anorexic response. PGE2 generation in liver may account for peripheral role of COX-2 in zymosan-...
