search for novel more effective insecticides, natural products could be used as ideal template compounds due to their good environmental compatibility, various bioactivities, unique scaffolds and mode of action. We have found that natural product evodiamine, the main active component from the fruits of Evodia rutaecarpa (Juss.) Benth, displayed obvious insecticidal activities against lepidoptera pests
在寻找新型更有效的杀虫剂时,天然产物具有良好的环境相容性、多种生物活性、独特的支架和作用方式,可作为理想的模板化合物。我们发现吴茱萸果实的主要活性成分天然产物吴茱萸碱对鳞翅目具有明显的杀虫活性。害虫。为了继续我们的研究,我们合理设计和合成了一系列吴茱萸碱衍生物3a-3aa。杀幼虫活性结果表明,大部分目标化合物对Mythimna separata、Plutella xylostella和Helicoverpa armigera的效果优于吴茱萸碱、苦参碱和鱼藤酮,其中3z表现出优异的杀幼虫活性(2.5 mg/L对M. separata的杀幼虫活性为65%, 75% 1.0 mg/L 对P. xylostella和 85% 10 mg/L 对H. armigera,分别),远优于吴茱萸碱(0%)、苦参碱(0%)和鱼藤酮(0%)。初步构效关系表明吴茱萸碱E环上的氟原子对杀幼虫活性有正向影响。钙显像
