of novel and efficient pesticides to combat increasingly resistant plant bacteria, in this work, 17 novel benzothiazole decorated penta-1,4-diene-3-one derivatives were designed and synthesized, the structures of all new compounds were systematically characterized via 1H-NMR, 13C-NMR, and HRMS. The results of the bioactivity study indicated that some compounds presented efficient antibacterial activity
为了寻找新的高效农药来对抗日益耐药的植物细菌,在这项工作中,设计和合成了 17 种新型苯并噻唑修饰的 penta-1,4-diene-3-one 衍生物,所有新化合物的结构通过1 H-NMR、13 C-NMR 和 HRMS。生物活性研究结果表明,一些化合物对米黄单胞菌具有有效的抗菌活性。Oryzae ( Xoo ) 和Xanthomonas axonopodis pv。柑橘(西科)。其中,化合物3i和3q的EC 50值最低,分别为11.9和28.5 μg ml -1分别对Xoo和Xac,它们都比硫二唑铜(分别为 109.3 和 87.6 μg ml -1)和双美噻唑(分别为 73.5 和 55.4 μg ml -1 )的效果更好。此外,SEM 图像进一步验证了目标化合物3i可以明显地破坏Xoo的细胞膜。
