phenyl ring, and 4-(1-oxido-4-pyridyl)-3-phenyl-2(5H)furanone (12) were designed and synthesized for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors. In vitro COX-1/COX-2 enzyme inhibition studies showed that 3-phenyl-4-(4-sulfonylazidophenyl)-2(5H)furanone (7d) inhibited COX-1 selectively (COX-1 IC50 = 0.6659 μM; COX-2 IC50 > 100 μM) and 3-(4-fluorophenyl)-4-(4-sulfonylazidophenyl)-2(5H)furanone
