以弥拜霉素类似物依维菌素为原料, 根据类同合成法和亚结构连接法原理, 对依维菌素进行脱糖, 再与相应的酰氯进行酯化、肟化反应制得两个系列弥拜霉素类似物化合物4Ia~5IId, 所有目标化合物都通过核磁共振氢谱、高分辨质谱的确认, 并分别对朱砂叶螨(Tetranychus cinnabarinus)、南方粘虫(Mythimna sepatara)和蚕豆蚜(Aphis fabae)进行室内杀虫活性测定, 结果表明所有衍生物均表现出不同程度的杀虫活性, 其中化合物4IIa 和4IIb 对粘虫和蚜虫表现出很高的杀虫活性.

Two series of milbemycin analogues containing ester and methoxy oxime groups were designed according to analog synthesis and sub-structure ligation from deglycosyl ivermectin, which is the analogue of milbemycin. The analogues reaction was carried out with the corresponding aromatic chloride, and the structures of the target compounds were confirmed by 1H NMR and high resolution mass spectra (HRMS). The insecticidal activities of 18 analogues against Tetranychus cinnabarinus, Mythimna sepatara and Aphis fabae were tested. The results showed that all analogues had different degree of insecticidal activity, especially compounds 4IIa and 4IIb showed the highest insecticidal activities against Mythimna sepatara and Aphis fabae.

Key words: milbemycin analogues, synthesis, biological activity
