Based on the original structure of harmine, several novel 1,2,3,4-tetrahydro-β-carboline, β-carboline and 1-substituted-β-carboline derivatives bearing a substituted carbohydrazide group at C-3 were designed and synthesized to investigate the structure-activity relationship of their analogues. All of the compounds were characterized by infrared (IR), proton and carbon nuclear magnetic resonance (1H-NMR, 13C-NMR), and mass spectroscopy (MS). The bioassay tests showed that N'-benzylidene-1-phenyl-β-carboline-3-carbohydrazide (C25H18N4O, m.w. 390.4) (c2) and N'-(4-trifluoromethyl-benzylidene)-1-phenyl-β-carboline-3-carbohydrazide (C26H17N4OF3, m.w. 458) (d2) exhibited good inhibitory activity against dicotyledonous and monocotyledonous weeds, with EC50 values of 4.83 µM and 14.25 µM, respectively.
基于哈马灵的原始结构,设计并合成了几种新型1,2,3,4-四氢-β-咔啉、β-咔啉和1-取代的β-咔啉衍生物,这些衍生物在C-3位上带有取代的碳酰肼基团,以研究其类似物的构效关系。所有化合物均通过红外光谱(IR)、质子和碳核磁共振(1H-NMR, 13C-NMR)以及质谱(MS)进行了表征。生物测定试验显示,N'-苄叉-1-苯基-β-咔啉-3-碳酰肼(C25H18N4O,分子量390.4)(c2)和N'-(4-三氟甲基-苄叉)-1-苯基-β-咔啉-3-碳酰肼(C26H17N4OF3,分子量458)(d2)对双子叶和单子叶杂草表现出良好的抑制活性,其EC50值分别为4.83 µM和14.25 µM。
