6-methyl-4-oxo-N-(5-(propylthio)-1, 3, 4-thiadiazol-2-yl)thiochromane-2-carboxamide (5m) showed a better antifungal activity against Botrytis cinerea (B. cinerea), with an inhibition rate of 69%, than carbendazim. As far as we know, this is the first report on the antibacterial and antifungal activities of this series of novel thiochroman-4-one derivatives incorporating carboxamide and 1, 3, 4-thiadiazole thioether
合成了一系列新型 thiochroman-4-one 衍生物,其中包含羧酰胺和 1, 3, 4-噻二唑硫醚部分。生物测定结果表明化合物 6-氯-N- (5-(甲硫基)-1, 3, 4-thiadiazol-2-yl)-4-oxothiochromane-2-carboxamide (5a) 对米黄单胞菌pv的 EC 50值. Oryzae ( Xoo ) 和Xanthomonas axonopodis pv 。Citri ( Xac ) 分别为 24 和 30 μ g/mL,甚至优于双甲基噻唑和噻二唑铜。同时,化合物 6-methyl-4-oxo- N-(5-(丙硫基)-1, 3, 4-thiadiazol-2-yl)thiochromane-2-carboxamide (5m) 对灰霉病菌(B. cinerea)表现出较好的抗真菌活性,抑菌率为 69%,比多菌灵。据我们所知,这是首次报道了这一系列结合了甲酰胺和1
