virtual screening based on the 3D structure of the subunit H of V-ATPase in previous study. 74 benzenesulfonyl derivatives were synthesized and their insecticidal activities were evaluated. The derivatives with propargyl substituents exhibit excellent insecticidal activities against Mythimna separata Walker. The LD50 values of compounds A5.7 (28.0 μg·g−1) and B5.7 (36.4 μg·g−1) were significantly less than
在先前的研究中,基于V-ATPase H亚基H的3D结构,通过虚拟筛选发现了两种含苯磺酰胺的先导化合物。合成了74个苯磺酰基衍生物,并对其杀虫活性进行了评价。具有炔丙基取代基的衍生物对Mythimna separata Walker表现出优异的杀虫活性。的LD 50个的化合物的值A5.7(28.0微克·克-1)和B5.7(36.4微克·克-1)均高于苦皮藤素Ⅴ的显著以下(344.0微克·克-1)。此外,等温滴定热量法(ITC)数据表明A5.7之间存在很强的结合亲和力 这些结果表明,这是开发针对V-ATPase H亚基的农药的实用方法。
