Abstract: N-methyl-N-(4-chlorophenyl) 4-aminobenzenesulfonamide and N-methyl-N-(4-aminophenyl) 4-chlorobenzenesulfonamide, which possess a p-amino group on the benzenesulfonyl moiety and p-chloro group on the anilino moiety, showed COX-1-selective inhibition. Moreover, N-methyl-N-(4-chlorophenyl) 4-aminobenzenesulfonamide, which is the most potent compound in this study showed more potent analgesic activity than that of aspirin at 30 mg/kg by po. The anti-inflammatory activity and gastric damage, however, were very weak or not detectably different from aspirin. Since the structure of our COX-1 inhibitors are very simple, they may be useful as lead compounds for superior COX-1 inhibitors as analgesic agents without gastric disturbance.
