A series of new N-phenylacetamide derivatives containing 4-arylthiazole moieties was designed and synthesized by introducing the thiazole moiety into the amide scaffold. The structures of the target compounds were confirmed by 1H-NMR, 13C-NMR and HRMS. Their in vitro antibacterial activities were evaluated against three kinds of bacteria—Xanthomonas oryzae pv. Oryzae (Xoo), Xanthomonas axonopodis pv
通过将噻唑部分引入酰胺支架中,设计并合成了一系列含有4-芳基噻唑部分的新型N-苯基乙酰胺衍生物。目标化合物的结构经1H-NMR、13C-NMR和HRMS确证。评估了它们对三种细菌——米黄单胞菌 pv. 的体外抗菌活性。Oryzae (Xoo), Xanthomonas axonopodis pv。Citri (Xac) 和 X.oryzae pv。oryzicola (Xoc)——显示出有希望的结果。N-(4-((4-(4-氟-苯基)噻唑-2-基)氨基)苯基)乙酰胺(A1)的最小50%有效浓度(EC50)值为156.7 µM,优于双硫噻唑(230.5 µM) 和硫二唑铜 (545.2 µM)。扫描电子显微镜 (SEM) 研究证实,化合物 A1 可能导致 Xoo 的细胞膜破裂。此外,还测试了化合物对南方根结线虫 (M. incognita) 的杀线虫活性,化合物 A23 表现出优异的杀线虫活性,在
