A series of β-amino alcohols were prepared by the reaction of eugenol epoxide with aliphatic and aromatic amine nucleophiles. The synthesized compounds were fully characterized and evaluated as potential insecticides through the assessment of their biological activity against Sf9 insect cells, compared with a commercial synthetic pesticide (chlorpyrifos, CHPY).

通过丁香酚环氧化物与脂肪族和芳香族胺亲核试剂反应制备了一系列β-氨基醇。通过评估合成的化合物对Sf9的生物活性,对其进行了充分表征并评估为潜在的杀虫剂昆虫细胞,与商业合成农药(毒死蜱,CHPY)相比。三种带有末端苯环的衍生物(取代或未取代)被确定为最有效的分子,其中两种对昆虫细胞的毒性高于 CHPY。此外,最有前途的分子能够增加对细胞凋亡至关重要的丝氨酸蛋白酶(半胱天冬酶)的活性,并且对昆虫细胞的毒性比人类细胞更大。基于结构的倒置虚拟筛选和分子动力学模拟表明,这些分子可能靶向乙酰胆碱酯酶和/或昆虫气味结合蛋白,并且能够与这些蛋白质形成稳定的复合物。对活性最强的化合物进行了 DMPG 和 DPPC/DMPG (1:1) 脂质体中的包封试验,并获得了高封装效率。实现了一种热敏制剂,化合物在更高的温度下释放更有效。
