Thirty phenolic ether derivatives of scopoletin modified at the 7-hydroxy position were synthesized, and their structures were confirmed by IR, ¹H-NMR, 13C-NMR, MS and elemental analysis. Preliminary acaricidal activities of these compounds against female adults of Tetranychus cinnabarinus (Boisduval) were evaluated using the slide-dip method. The results indicated that some of these compounds exhibit
合成了30个7位羟基修饰的东莨菪碱酚醚衍生物,并通过IR、~(1H)NMR、~(13)C-NMR、MS和元素分析确证了其结构。使用玻片浸渍法评估了这些化合物对朱砂叶螨 (Boisduval) 雌性成虫的初步杀螨活性。结果表明,其中一些化合物表现出比东莨菪碱更显着的杀螨活性,特别是化合物32、20、28、27和8,其表现出约8.41、7.32、7.23、6.76和6.65倍的杀螨效力。化合物32具有最有希望的杀螨活性,并且对朱砂螨的杀螨效力比克螨特高约1.45倍。具有统计显着性的 2D-QSAR 模型支持观察到的杀螨活性,并揭示极化性 (HATS5p) 是控制生物活性的最重要参数。3D-QSAR(CoMFA:q² = 0.802,r² = 0.993;CoMSIA:q² = 0.735,r² = 0.965)结果表明,R₄,R₁,R2和R₅(C₆,C₃,C₄和C₇)位置的大取代基,电子R₅(
