discover biorational natural products-based insecticides, two series (27) of novel 9R/S-acyloxy derivatives of cinchonidine and cinchonine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially derivatives 6l and 6o exhibited the best insecticidal activity with final mortality rates of 75
摘要 努力发现基于生物理性天然产物的杀虫剂,制备了两类(27)新的辛可尼定和辛可宁的9 R / S-酰氧基衍生物,并通过叶浸法以1 mg的剂量评估了它们对体内Mythimna separata的杀虫活性。/毫升 在所有化合物中,尤其是衍生物6l和6o表现出最好的杀虫活性,最终死亡率分别为75.0%和71.4%。总的来说,游离的9-羟基不是杀虫活性的先决条件,并且C9取代具有良好的耐受性。C8 / 9位的构型对于杀虫活性是重要的,而9 S构型是最佳的。6'-OCH 3 部分不是必需的,也可以将其除去。
