摘要：[目的]为将光药理学方法应用于农药学研究。[方法]在阿维菌素B1a分子的C5-OH引入光致异构基团偶氮苯。[结果]合成了3个偶氮苯-阿维菌素衍生物,测试了光物理化学性质和生物活性。这些衍生物光致异构反应的转化率为42%~47%,具有良好的抗疲劳性和热稳定性。化合物3a对蚊幼虫和黏虫、3c对蚊幼虫的活性较好,但光照前后活性差异较小。[结论]偶氮苯-阿维菌素衍生物的顺反异构变化可以被光可逆控制,具有成为新型光控活性分子的潜能。
[Aims] The paper aims to apply photopharmacology to pesticide research. [Methods] Azobenzene photoswitches were introduced to avermectin BB1a at C5 site. [Results] Three avermectin-azobenzene derivatives were synthesized, and their photochromic properties as well as insecticidal activities were evaluated. The photoisomerization ratios of the compounds were 42-47%. They all had excellent fatigue resistance and thermostability. Compound 3 a possessed good activities against Culex pipiens pallens and Mythimna separate, as well as 3 c had good activities against C. pipiens pallens. However, all derivatives did not exhibit obvious activity difference before and after irradiation.[Conclusions] Avermectin-azobenzene derivatives can be reversibly switched between trans and cis form by UV/blue light, indicating their potential of novel light-controlled pesticide.
