To promote the development and exploitation of novel antifungal agents, a series of thiazol-2-ylbenzamide derivatives (-) and thiazole-2-ylbenzimidoyl chloride derivatives (-) were designed and selective synthesis. The bioassay results showed that most of the target compounds exhibited excellent antifungal activities against five plant pathogenic fungi (, , , and ). The antifungal effects of compounds
为了促进新型抗真菌药物的开发利用,设计并选择性合成了一系列噻唑-2-基苯甲酰胺衍生物(-)和噻唑-2-基苯甲酰氯衍生物(-)。生物测定结果表明,大部分目标化合物对5种植物病原真菌(、、、和)表现出优异的抗真菌活性。化合物(EC = 0.72 mg/L)和(EC = 0.65 mg/L)的抗真菌作用与琥珀酸脱氢酶抑制剂(SDHI)(EC = 1.08 mg/L)和(EC = 0.78 mg/L)相当。特别是,化合物(EC = 0.87 mg/L)和(EC = 1.08 mg/L)表现出比(EC = 2.25 mg/L)更高的活性。稻叶实验表明,化合物(86.8%)和(85.3%)表现出与(88.5%)相当的优异保护活性。扫描电子显微镜(SEM)结果表明,该化合物极大地破坏了菌丝体的典型结构和形态。分子对接表明化合物 和 与琥珀酸脱氢酶 (SDH) 具有显着的相互作用。同时,SDH抑制实验结果
