Diamide insecticides, represented by chlorantraniliprole (CHL), were widely applied in the control of lepidopteran insects. In efforts to develop bioactive diamides with novel scaffolds, we design and synthesized a series of diamides containing central amino acids to conformationally simulate CHL. Bioassay results indicated that most compounds containing 1-aminocyclopropane-1-carboxylic acid exhibited
以氯虫苯甲酰胺(CHL)为代表的二酰胺类杀虫剂广泛应用于鳞翅目昆虫的防治。为了开发具有新型支架的生物活性二酰胺,我们设计并合成了一系列含有中心氨基酸的二酰胺,以在构象上模拟 CHL。生物测定结果表明,大多数含有 1-氨基环丙烷-1-羧酸的化合物对Mythimna separate和Plutella xylostella表现出优异的杀幼虫效力。经过系统的结构-活性关系研究,1-23被确定为潜在的杀虫剂候选物,其 LC 50值分别为 34.920 mg·L -1和61.992 mg·L -1在P. xylostella上。最后,分子对接揭示了1-23与靶蛋白兰尼碱受体的可能结合模式。
