structure determination, while single-crystal X-ray diffraction was employed for certain compounds. Meanwhile, the insecticidal activities against Mythimna separata were also assessed. Some of the compounds exhibited significantly enhanced activity, the LC50 value of the highest activity compound TD8 (0.231 mg/mL) demonstrating respective increases by 100-fold compared to the plant pesticide celangulin V
农业害虫是农作物减产的主要因素,特别是在欠发达地区。尽管农药在害虫防治方面具有显着功效,但其广泛使用导致了杀虫剂的抗药性。开发新型环保植物源农药已刻不容缓。本研究设计了一系列含有炔丙氧基和磺酰胺基团的二芳基醚化合物。这36种化合物的合成主要依靠核磁共振进行结构测定,部分化合物还采用单晶X射线衍射。同时,还评估了对粘虫的杀虫活性。部分化合物的活性显着增强,活性最高的化合物TD 8 (0.231 mg/mL)的LC 50值分别比植物农药苦皮藤素V (23.9 mg/mL)提高了100倍,5阳性对照 L-1 (1.261 mg/mL) 增加倍。通过症状分析和分子对接验证了目标化合物与目标之间的相互作用以及目标的一致性。还进行了结构-活性关系。这项研究为未来农药的进步和配方提供了一条新的轨迹。
