Microwave‐Assisted Synthesis and Antiprotozoal Activity of Pyridazines Carrying Polyfluoro Substituents
摘要:
A number of 4,5-dichloro- and 4,5-dibromopyridazin-3-ones and - 3,6-diones with polyfluoro substituents at position 2 were obtained in good yields by microwave-assisted method. The oxopyridazines as well as their respective 5-dimethylaminoethylamino derivatives were tested for antibacterial, antiviral, and antiprotozoal activity.

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 selectively of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
