4-d]pyrimidine derivatives that have antimicrobial activities. A novel series of 4-substituted-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine derivatives including hydrazones (4a–i and 5), pyrazoles (6a, b) and (8), and oxadiazole-2-thiol (7), has been synthesized. Compounds 4g, 4b, 4h, 4d, 6a, 7, 8 have shown that some of the synthesized compounds have a moderate to outstanding antimicrobial activity against
这项研究的目的是探索合成具有抗菌活性的吡唑并[3,4- d ]嘧啶衍生物的可能性。一系列新的4-取代-1-苯基-1 H-吡唑并[3,4- d ]嘧啶衍生物,包括(4a-1和5),吡唑(6a,b)和(8)以及恶二唑-2 -硫醇(7),已经合成。化合物4g,4b,4h,4d,6a,7、8已显示某些合成的化合物对革兰氏阳性菌具有中等至突出的抗菌活性:肺炎链球菌和枯草芽孢杆菌,革兰氏阴性菌:铜绿假单胞菌和大肠杆菌以及真菌:烟曲霉和白色念珠菌菌株。有趣的是,化合物(7) “ 5-[((1-苯基-1 H-吡唑并[3,4- d ]嘧啶-4-基)氨基]甲基} -1,3,4-恶二唑-2-硫醇”与氨苄青霉素和庆大霉素相比,它具有更好的抗菌活性,这表明它可以用作进一步研究的先导化合物。
