  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 range of 1,3,4‐oxadiazoles have been synthesized using a UV‐B activated flow approach starting from carboxylic acids and 5‐substituted tetrazoles. The application of UV light represents an attractive alternative to the traditional thermolytic approach and has demonstrated comparable efficiency and versatility, with a diverse substrate scope, including the incorporation of highly substituted amino

  已使用UV-B活化流动法从羧酸和5-取代的四唑合成了1,3,4-恶二唑。紫外线的应用代表了传统热解方法的一种有吸引力的替代方法，并已证明具有可比的效率和多功能性，具有多种底物范围，包括掺入高度取代的氨基酸。

  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。
