been considered as a promising fungicide target discovered in our previous studies. Natural compounds are important sources for discovery and development of new pesticides. To continue our ongoing studies on the discovery of novel PK-targeted fungicides, a series of novel psoralen derivatives including a 1,3,4-oxadiazole moiety were designed by a computer-aided pesticide molecular design method, synthesized
在我们之前的研究中,丙酮酸激酶(PK)被认为是一种很有前途的杀菌剂靶标。天然化合物是发现和开发新农药的重要来源。为了继续我们正在进行的关于发现新型 PK 靶向杀菌剂的研究,通过计算机辅助农药分子设计方法设计了一系列包括 1,3,4-恶二唑部分的新型补骨脂素衍生物,合成并评估了它们的杀菌剂活动。生物测定结果表明,化合物11d、11e、11g、11i和12a对灰葡萄孢具有优异的体外杀菌活性,EC 50值分别为 4.8、3.3、6.3、5.4 和 3.9 μg/mL。它们比相应的阳性对照 YZK-C22 [3-(4-methyl-1,2,3-thiadiazol-5-yl)-6-(trichloromethyl)-[1,2,4]-triazolo-[ 3,4- b ][1,3,4]-噻二唑](EC 50值为 13.4 μg/mL)。化合物11g和11i在 200 μg/mL 的浓度下分别表现出对
