In this work, a series of novel indole 3-substituted-[1,2,4]triazole derivatives was designed and synthesized, and their structures were characterized by 1H, 13C NMR, high-resolution mass spectrometry, and single-crystal diffraction. Moreover, the antibacterial activities of the title compounds were evaluated against Xanthomonas oryzae pv. oryzae (Xoo), Pseudomonas syringae pv. actinidae (Psa), and
本工作设计合成了一系列新型吲哚3-取代-[1,2,4]三唑衍生物,并通过1 H、13 C NMR、高分辨质谱和单晶等对其结构进行了表征。衍射。此外,还评估了标题化合物对Xanthomonas oryzae pv. 的抗菌活性。oryzae ( Xoo ),丁香假单胞菌pv。actinidae ( Psa ) 和Xanthomonas axonopodis pv。citri ( Xac ) 采用比浊法。结果表明,标题化合物对Xoo具有优异的生物活性,其50%有效浓度(EC 50 )为2.32~35.4 µg/mL,优于阳性对照药双美噻唑(38.6 µg/mL)和噻二唑铜(58.4 µg/mL)。特别是,化合物53和9对Xoo的 EC 50值分别为 3.1 和 2.3 µg/mL。 图形概要
