A series of novel mandelic acid derivatives containing a 1,3,4-oxadiazothioether moiety were designed and synthesized. Bioassay results showed that some target compounds exhibited certain antifungal activity against six kinds of pathogenic fungi in vitro. Among the compounds, the EC50 values of T41 against Gibberella saubinetii, Verticillium dahlia and Sclerotinia sclerotiorum were 31.0, 27.0 and 32
设计并合成了一系列含有 1,3,4-oxadiazothioether 部分的新型扁桃酸衍生物。生物测定结果表明,部分目标化合物在体外对六种病原真菌表现出一定的抗真菌活性。在这些化合物中,EC 50值Ť 41对赤saubinetii,黄萎病大丽花和菌核病为31.0,27.0和32.1微克/毫升,分别与EC 50的值Ť 14对抗核盘菌为14.7微克/毫升。对抗性真菌核盘菌的抗真菌活性表明该系列目标化合物可能具有与商品化的琥珀酸脱氢酶抑制剂carboxin相似的作用方式或位点。用荧光显微镜进行的形态学研究表明,T 41可以显着破坏G的膜完整性。saubinetii。
