Methanesulfonamide group at position-4 of the C-5-phenyl ring of 1,5-diarylpyrazole affords a potent class of cyclooxygenase-2 (COX-2) inhibitors.
The effect of methanesulfonamide (MeSO(2)NH) group on COX-2 inhibitory activity of 1,5-diarylpyrazole is described. While this group being at position-4 of the N(1)-phenyl ring was found to beExpand

2-hydroxymethyl-4-[5-(4-methoxyphenyl)-3-trifluoromethyl-1H-1-pyrazolyl]-1-benzenesulfonamide (DRF-4367): an orally active COX-2 inhibitor identified through pharmacophoric modulation.
Analogs of 1,5-diarylpyrazoles with a novel pharmacophore at N1 were designed, synthesized and evaluated for the in-vitro cyclooxygenase (COX-1/COX-2) inhibitory activity. The variations at/aroundExpand

Identification of 2-hydroxymethyl-4-[5-(4-methoxyphenyl)-3-trifluoromethyl-pyrazol-1-yl]-N-propionylbenzenesulfonamide sodium as a potential COX-2 inhibitor for oral and parenteral administration.
Synthesis of prodrugs of orally active COX-2 inhibitor 3 involving sulfamoyl (SO(2)NH(2)) and hydroxymethyl (CH(2)OH) groups, and their biological evaluation are described. Of these prodrugs, theExpand
