  Inhibition of Tobacco Bacterial Wilt with Sulfone Derivatives Containing an 1,3,4-Oxadiazole Moiety

  摘要：

  A series of new sulfone compounds containing the 1,3,4-oxadiazole moiety were designed and synthesized. Their structures were identified by H-1 and C-13 nuclear magnetic resonance and elemental analyses. Antibacterial bioassays indicated that most compounds exhibited promising in vitro antibacterial bioactivities against tobacco bacterial wilt at 200 mu g/mL. The relationship between structure and antibacterial activity was also discussed. Among the title compounds, 5'c:, 5'h, 5'i, and 5, could inhibit mycelia growth of Ralstonia solanacearum in vitro by approximately 50% (EC50) at 39.8, 60.3, 47.9, and 32.1 mu g/mL, respectively. Among them, compound 5) was identified as the most promising candidate due to its stronger effect than that of Kocide 3000 [Cu(OH)(2)] within the same concentration range. Field trials demonstrated that the control effect of compound 55 against tobacco bacterial wilt was better than that of the commercial bactericide Saisentong. For the first time, the present work demonstrated that sulfone derivatives containing 1,3,4-oxadiazole can be used to develop potential bactericides for plants.

  1,3,4-恶二唑硫醚 4H-Chromen-4-one 衍生物的抗菌和抗病毒活性

  摘要：

  设想了各种 1,3,4-恶二唑硫醚 4 H -chromen-4-one 衍生物。标题化合物对Xac、Psa和Xoo显示出惊人的抑制作用。EC 50数据表明，A8 (19.7 μg/mL) 对Xoo 的抗菌活性优于杨梅素、BT 和 TC。同时，A8的作用机制已通过扫描电镜验证。抗烟草花叶病毒结果表明，与宁南霉素相比，A9的体内抗病毒效果最好。从 MST 的数据可以看出，A9(0.003±0.001μmol/L)表现出很强的结合能力，远优于宁南霉素(2.726±1.301μmol/L)。本研究表明，1,3,4-恶二唑硫醚4H -chromen-4-one衍生物可能成为极具潜力的农用药物。

  inhibitory effects against Xac, Psa, and Xoo. EC50 data exhibited that A8 (19.7 μg/mL) had better antibacterial activity against Xoo than myricetin, BT, and TC. Simultaneously, the mechanism of action of A8 had been verified by SEM. The results of anti-tobacco mosaic virus indicated that A9 had the best in vivo antiviral effect compared with ningnanmycin. From the data of MST, it could be seen that A9 (0.003
