Marine natural products polycarpine, polycarpaurines A and C, and their derivatives were designed, synthesized, and characterized on the basis of 1H NMR and mass spectroscopy. The antiviral and antiphytopathogenic fungus activities of these alkaloids were first evaluated. Polycarpine derivative 1g displayed excellent in vivo antiviral activity against TMV (inactivation inhibitory effect, 57%/500 μg
在1 H NMR和质谱的基础上,设计,合成和表征了海洋天然产物多香果素,多香豆素A和C及其衍生物。首先评估了这些生物碱的抗病毒和抗植物病原真菌活性。1克多果芸香碱衍生物对TMV表现出出色的体内抗病毒活性(灭活抑制作用,分别为57%/ 500μgmL –1和19%/ 100μgmL –1;根治性抑制作用为62%/ 500μgmL –1和23%/ 100μgmL –1;和保护抑制作用,分别为56%/ 500μgmL –1和29%/ 100μgmL –1),其活性明显高于利巴韦林的活性(灭活抑制作用为37%/ 500μgmL –1和9%/ 100μgmL –1;治愈抑制作用为36%/ 500μgmL –1和13%/ 100μgmL –1;以及39%/ 500μgmL –1和17%/ 100μgmL –1的保护抑制作用,因此成为针对TMV的抗病毒研究的新的先导化合物。体外杀真菌试验表明,大多数化合
