simplification of furofuran lignan phrymarolin II, and their antiviral and antibacterial activities were systematically evaluated. The bioassay results showed that compound A24 displayed remarkable inactivation activity against tobacco mosaic virus (TMV) with an EC50 value of 130.4 μg/mL, which was superior to that of commercial ningnanmycin (EC50 = 202.0 μg/mL). The antiviral mode of action assays suggested
天然产物一直是高效、低风险农药的宝贵来源。本工作通过呋喃呋喃木脂素富马林II的结构简化,设计合成了一系列新型芝麻林衍生物A0-A31和B0-B4 ,并系统评价了它们的抗病毒和抗菌活性。生物测定结果表明,化合物A24对烟草花叶病毒(TMV)具有显着的灭活活性,EC 50值为130.4 μg/mL,优于市售宁南霉素(EC 50 = 202.0 μg/mL)。抗病毒作用模式测定表明,化合物A24可能通过与 TMV 外壳蛋白 (CP) 结合来阻碍自组装,从而抵抗 TMV 感染。此外,化合物A25具有显着的抗菌活性,特别是对青枯菌,EC 50值为43.8 μg/mL,优于市售的双噻唑和噻二唑铜。该研究为呋喃喃木脂素在作物保护中的应用奠定了坚实的基础。
