  Design and synthesis of novel 2-phenyl-5-(1,3-diphenyl-1H-pyrazol-4-yl)-1,3,4-oxadiazoles as selective COX-2 inhibitors with potent anti-inflammatory activity

  摘要：

  A novel series of 2-phenyl-5-(1,3-diphenyl-1H-pyrazol-4-yl)-1,3,4-oxadiazoles were designed and synthesized for selective COX-2 inhibition with potent anti-inflammatory activity. Among the compounds tested, 9g (2-(3-(4-nitrophenyl)-1-phenyl-1H-pyrazol-4-yl)-5-phenyl-1,3,4-oxadiazole) was found to be the most potent inhibitor of COX-2 with IC50 of 0.31 μM showing promising degree of anti-inflammatory activity in the carrageenan-induced rat paw edema model with ED50 of 74.3 mg/kg. The lead compound 9g further showed suppression of acetic acid-induced writhes comparable to that of aspirin and gastro-sparing profile superior to the aspirin. Molecular docking analysis displayed higher binding affinity of ligands towards COX-2 than COX-1.

  A series of novel 2,5-disubstituted 1,3,4-oxadiazoles 4 have been conveniently synthesized by oxidative cyclization of pyrazolylaldehyde N-acylhydrazones 3 promoted by iodobenzene diacetate under mild conditions (11 examples, up to 92% isolated yields). All the eleven compounds were tested in vitro for their antibacterial activity against Gram-positive bacteria namely, Staphylococcus aureus, Bacillus

  通过在温和条件下由碘代苯二乙酸酯促进的吡唑基醛N-酰基hydr酮3的氧化环化反应，可以方便地合成一系列新颖的2,5-二取代的1,3,4-恶二唑4（11个实例，分离产率高达92％）。在体外测试了所有这11种化合物对革兰氏阳性菌，即金黄色葡萄球菌，枯草芽孢杆菌和两种革兰氏阴性菌，即大肠杆菌和铜绿假单胞菌的抗菌活性。还测试了所有合成的化合物对两种真菌的抑制作用。
