cellular leakage, and cellular permeability. Enzyme activity assays and molecular docking studies indicated that Z2 could act as a potential succinate dehydrogenase inhibitor (SDHI). It was hypothesized that Z2 could cause disruption of mycelial cell membranes, which in turn leads to mycelial death. According to the research, indole derivatives containing 1,3,4-thiadiazole were expected to evolve
本研究发现并合成了24种含有1,3,4-噻二唑的吲哚衍生物。然后在体外测定了目标化合物对 14 种植物病原真菌病原体的抗真菌功效。 Z2的 EC 50值为 2.7 μg/mL,表现出其中针对灰葡萄孢( Bc .) 的最高水平的生物活性,超过了对照处方药嘧菌酯 (Az) 的浓度 (EC 50 = 14.5 μg/mL) 和氟吡菌酰胺 (Fl) (EC 50 = 10.1 μg/mL)。 Z2在蓝莓叶上进行了体内测试,以评估其在现实环境中的有用性。在200 μg/mL浓度下获得了合理的保护效果,防效为93.0%,优于Az(83.0%)和Fl(52.0%)。在200μg/mL时,该化学品的疗效为84.0%。这些数字优于 Az (69.0%) 和 Fl (48.0%)。扫描电镜(SEM)实验和光镜实验表明, Z2改变了病原真菌Bc .细胞壁和细胞膜的完整性,导致丙二醛(MDA)含量增加,细胞渗漏,
