Prostaglandin endoperoxide H synthase biosynthesis inhibitors

, (2008/06/13)
The present invention describes pyridazinone compounds of formula I which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important “housekeeping” enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).

The reaction of 2-substituted-4,5-dichloro-3(2H)-pyridazinones 1a-b with alkoxides and alkylthiolates was investigated.Regiospecific displacement of either the 4 or 5 chlorine atom could be achieved in most cases by appropriate selection of the reaction solvent.
