were synthesized and evaluated for their fungicidal activity. Most of these compounds exhibited excellent fungicidal activity in vitro. Significantly, compound 2e displayed the superior in vitro antifungal activity against Sclerotinia sclerotiorum, Rhizoctonia solani, Botrytis cinerea, and Fusarium graminearum with the EC50 values of 0.39, 0.46, 0.19, and 0.18 μg/mL, respectively, and were more potent
受天然 2-喹啉羧酸衍生物的启发,合成了一系列含有酰肼、酰腙、磺酰肼、恶二唑、噻二唑或三唑部分的喹啉化合物,并评估了它们的杀菌活性。大多数这些化合物在体外表现出极好的杀真菌活性。值得注意的是,化合物2e对核盘菌、立枯丝核菌、灰葡萄孢和禾谷镰刀菌显示出优异的体外抗真菌活性,EC 50值分别为 0.39、0.46、0.19 和 0.18 μg/mL,并且更有效。多菌灵(EC50,0.68,0.14,> 100,和0.65微克/毫升,分别地)。此外,化合物2e可以抑制禾谷镰刀菌的孢子萌发。初步机理研究表明,化合物2e可引起细胞壁和液泡形态异常、线粒体丢失、膜通透性增加和细胞内容物释放。这些结果表明,化合物2e表现出优异的杀真菌活性,可能是对抗植物真菌病害的潜在杀真菌候选物。
