inhibitory activity against Xanthomonas oryzae pv. oryzae, Xanthomonas oryzae pv. oryzicolaby, and Xanthomonas axonopodis pv. citri, with the EC50 values of 8.67, 12.65, and 10.62 μg/mL, which were superior to those of Bismerthiazol and Thiodiazole-copper. Meanwhile, bioassay results showed that all of the target compounds proved to have lower antifungal activities against Sclerotinia sclerotiorum, Fusarium
设计并合成了一系列含有磺酰基部分的新型硫代苯并二氢吡喃酮衍生物。它们的结构通过1 H-NMR,13 C-NMR和HRMS确定。生物测定结果表明,大多数目标化合物对米生黄单胞菌pv表现出中等至良好的抗菌活性。菌,黄单胞菌光伏。oryzicolaby和Xanthomonas axonopodis pv。红蜘蛛。化合物4i对米黄单胞菌pv具有最佳的抑制活性。菌,黄单胞菌光伏。Oryzicolaby和Xanthomonas axonopodis pv。citri的EC 50值为8.67、12.65和10.62μg/ mL,优于Bismerthiazol和Thiodiazole-copper的EC 50值。同时,生物测定结果表明,所有被证明目标化合物的具有抗较低的抗真菌活性菌核病,尖镰孢,玉蜀黍赤霉,立枯丝核菌,轮枝大丽花和灰霉病比多菌灵。
