Abstract A novel heterocyclic compounds containing pyrimido[4,5-d]pyrimidine (IIIa–IIIb) and (IVa–IVb), pyrazolo[3,4-d]pyrimidine (Va'–Ve') and (VIa'–VIe'), and pyrimido[4,5-b]quinoline (VIIa'–VIIe') and (VIIIa'–VIIIe') were designed and synthesized from the starting materials, 5-(bis(methylthio)methylene)-1,3-diphenylpyrimidine-2,4,6(1H,3H,5H)-trione (IIa) and 5-(bis(methylthio)methylene)-1,3-dip
摘要 一种新型杂环化合物,含有嘧啶并[4,5- d ]嘧啶(IIIa–IIIb)和(IVa–IVb)、吡唑并[3,4- d ]嘧啶(Va'–Ve')和(VIa'–VIe') ,以及嘧啶并[4,5- b ]喹啉(VIIa'–VIIe')和(VIIIa'–VIIIe')以5-(双(甲硫基)亚甲基)-1,3-二苯基嘧啶为原料设计并合成-2,4,6(1 H ,3 H ,5 H )-三酮 ( IIa ) 和 5-(双(甲硫基)亚甲基)-1,3-二苯基-2-硫代二氢嘧啶-4,6(1 H ,5据报道, H )-二酮 ( IIb ) 是有效的 α,α-乙烯酮二硫缩醛。此类化合物的合成方法将为新型活性杂环化合物的设计提供创新的分子框架。在我们的研究中,我们还提出了合成方法的优化以及对这些新合成的化合物作为抗菌剂针对细菌菌株(例如大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌和铜绿假单胞菌)的抗菌评估,也作为抗真菌剂
