agricultural production. In this study, a series of novel chalcone derivatives containing thioether triazoles were designed and synthesized. The structures of the novel compounds were systematically characterized via 1H‐NMR, 13C‐NMR, and HRMS. Moreover, the antibacterial activity results showed that E10, E11, E15, and E16 have adequate antibacterial activities against Xoo, Rs, and Xac. Among the different compounds
米糠黄单胞菌的感染。Oryzae(Xoo),Ralstonia solanacearum(Rs)和Xanthomonas axonopodis pv。柠檬(Xac)已成为农业生产中的主要问题。在这项研究中,设计并合成了一系列新型的含硫醚三唑的查尔酮衍生物。通过 1 H-NMR,13 C-NMR和HRMS系统地表征了新型化合物的结构。此外,抗菌活性结果表明,E 10,E 11,E 15和E 16对Xoo,Rs和Xac具有足够的抗菌活性。在不同的化合物中,E 15对Xac表现出显着的抑制作用,EC 50为9.1μg.mL -1,比商品试剂比美噻唑(54.9μg.mL -1)更好。另外,通过扫描电子显微镜(SEM)研究了目标化合物E 15对Xac的可能的抗菌机理。
