derivatives containing double 1,3,4-oxadiazole moiety was designed, synthesized and evaluated for their antibacterial activities in vitro. These compounds were fully characterized by 1H NMR, 13C NMR, and HRMS. Bioassay results indicated that most of title compounds exhibited excellent antibacterial activities against rice bacterial pathogen Xanthomonas oryzae (Xoo). For example, compounds 7d, 7h, 7i
摘要设计,合成了一系列含有双1,3,4-恶二唑部分的新型吲哚衍生物,并对其体外抗菌活性进行了评估。这些化合物通过1 H NMR,13 C NMR和HRMS进行了充分表征。生物测定结果表明,大多数标题化合物对水稻细菌病原体米黄单胞菌(Xanthomonas oryzae,Xoo)均表现出优异的抗菌活性。例如,化合物7d,7h,7i,7j,7k,7l和7m具有最大有效浓度的一半(EC 50)值分别为52.31、54.12、40.65、38.80、51.13、52.75和50.66 µg / mL,优于商品化的比美噻唑(BMT)(85.18 µg / mL)。实验结果证明,带有双1,3,4-恶二唑单元的吲哚衍生物有望成为开发新型农用杀菌剂以对抗致病菌Xoo的候选物。 图形概要
