LARGE CONDUCTANCE CALCIUM-ACTIVATED K CHANNEL OPENER

The present invention provides a large conductance calcium-activated K channel opener comprising a compound of the formula (I): wherein R1 and R3 are each sulfonamide, carbamoyl, acyl, amino, and the like, m and n are each 0 to 2, R2 and R4 are each cyano, nitro, hydroxyl, an alkoxy, a halogen, or an alkyl, Ring A is benzene or a heterocyclic ring, Ring B is benzene, a heterocyclic ring, a cycloalkane etc, and Ring Q is pyrazole or isoxazole, or a pharmaceutically acceptable salt thereof as an active ingredient.

Polar substitutions in the benzenesulfonamide ring of celecoxib afford a potent 1,5-diarylpyrazole class of COX-2 inhibitors

Several chemical modifications in the N1-benzenesulfonamide ring of celecoxib are presented. The series with a hydroxymethyl group adjacent to the sulfonamide was found to be the most potent modification that yielded many compounds selectively active against COX-2 enzyme in vitro.
