A series of novel phosphorylated penta-1,4-dien-3-one derivatives were designed and synthesized. The structures of all title compounds were determined by 1H-NMR, 13C-NMR, 31P-NMR, and high-resolution mass spectrometry (HRMS). Bioassay results showed that several of the title compounds exhibited remarkable antibacterial and antiviral activities. Among these, compound 3g exhibited substantial antibacterial
设计并合成了一系列新型磷酸化penta-1,4-dien-3-one 衍生物。所有标题化合物的结构均通过 1H-NMR、13C-NMR、31P-NMR 和高分辨率质谱 (HRMS) 测定。生物测定结果表明,几种标题化合物表现出显着的抗菌和抗病毒活性。其中,化合物 3g 对黄单胞菌 pv 表现出显着的抗菌活性。稻瘟病菌 (Xoo) 的 50% 有效浓度 (EC50) 值为 8.6 μg/mL,显着优于双甲噻唑 (BT) (58.8 μg/mL) 和硫代二唑铜 (TC) (78.7 μg/mL)。此外,化合物3h对烟草花叶病毒(TMV)表现出显着的保护活性,EC50值为104.2 μg/mL,优于宁南霉素(386.2 μg/mL)。此外,还研究了关于化合物 3h 和 3j 与 TMV 外壳蛋白 (TMV CP) 相互作用的微型热泳和分子对接实验。化合物3h和3j以0.028和0.23 μmol/L的解离常数与TMV
