favorable to the bioactivity. Subsequently, to improve the bioactivity of inhibitors via enhanced the interactions with important residues, a series of benzo[d][1,3]dioxole-6-benzamide derivatives were rationally designed and synthesized, and their inhibitory activities against Ostrinia furnacalis (O. furnacalis) chitinases, as well as insecticidal activities against O. furnacalis and Plutella xylostella
昆虫生长调节剂 (IGRs) 扰乱昆虫生理过程的正常发育,被公认为绿色杀虫剂。昆虫几丁质酶在蜕皮过程中的角质层降解中起着至关重要的作用,Of ChtI、Of ChtII 和Of Chi-h 是发现新型杀虫剂如 IGRs 的潜在目标。在我们之前的研究中,我们将先导化合物a12鉴定为一种有前途的多靶点抑制剂。在此,我们使用a12与三种几丁质酶的结合模式来识别有利于生物活性的关键相互作用和残基。随后,为了通过增强与重要残基的相互作用来提高抑制剂的生物活性,一系列苯并[ d][1,3]dioxole-6-benzamide衍生物的合理设计和合成,及其对亚洲玉米螟( O. furnacalis )几丁质酶的抑制活性,以及对亚洲玉米螟( O. furnacalis )和小菜蛾( P. xylostella )的杀虫活性。调查。其中,化合物d29同时作用于Of ChtI、Of ChtII和Of Chi-h,K
