  Design, synthesis, and antibacterial activity against rice bacterial leaf blight and leaf streak of 2,5-substituted-1,3,4-oxadiazole/thiadiazole sulfone derivative

  摘要：

  A series of 2,5-substituted-1,3,4-oxadiazole/thiadiazole sulfone derivatives were synthesized and evaluated for their antibacterial activities against rice bacterial leaf blight and leaf streak caused by Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicolaby via the turbidimeter test in vitro. Antibacterial bioassay results indicated that most compounds demonstrated good inhibitory effect antibacterial bioactivities against rice bacterial leaf blight and leaf streak. Among the title compounds, compound 6c demonstrated the best inhibitory effect against rice bacterial leaf blight and leaf streak with half-maximal effective concentration (EC50)values of 1.07 and 7.14 mu g/mL, respectively, which were even better than those of commercial agents such as Bismerthiazol and Thiediazole Copper. In vivo antibacterial activities tests at greenhouse conditions demonstrated that the controlling effect of compounds 6c (43.5%) and 6g (42.4%) against rice bacterial leaf blight were better than those of Bismerthiazol (25.5%) and Thiediazole Copper (37.5%).

  快速发现新型抗真菌药物：带有 quinazolin-4(3H)-one 片段的 1,3,4-恶二唑衍生物

  摘要：

  农业生产中爆发的抗性真菌的迅速出现，极大地促进了新型杀菌剂候选物的开发。为了发现新的抗真菌先导物，构建了一系列带有 quinazolin-4(3 H )-one 片段的 1,3,4-恶二唑衍生物，用于评估它们在体外和体内对植物病原真菌的抑制作用。生成系统的结构的优化的生物活性分子余32所识别作为对有希望的抑制剂纹枯病与体内200 μg/mL 时的预防效果为 58.63%。扫描电镜和透射电镜观察表明，生物活性分子I 32可以诱导菌丝的蔓延生长、菌丝表面的局部收缩和破裂、液泡的极度膨胀、细胞壁的显着变形、以及线粒体数量的减少。上述结果为发现带有喹唑啉-4(3 H )-one 和1,3,4-恶二唑片段的抗真菌先导物提供了不可或缺的补充。

  novel anthranilic diamide derivatives incorporating 1,3,4‐oxadiazole or nitrogen‐containing saturated heterocyclic moieties were synthesized, characterized, and evaluated for bacteriostatic activity against three phytopathogenic bacteria Xanthomonas oryzae pv. Oryzae (Xoo), Xanthomonas axonopodis pv. Citri (Xac), Ralstonia solanacearum (R. solanacearum). The preliminary biological results indicated that

  In this study, a series of 2-mercapto-5-substituted-1,3,4-oxadiazole/thiadiazole derivatives were synthesized and evaluated for their antibacterial activities against rice bacterial leaf blight and tomato bacterial wilt caused by Xanthomonas oryzae pv. oryzae (Xoo) and Ralstonia solanacearum (R. solanacearum) via the turbidimeter test in vitro. Antibacterial bioassays indicated that most compounds demonstrated appreciable antibacterial bioactivities against Xoo and R. solanacearum. Among the title compounds, compound 4i demonstrated the best inhibitory effect against Xoo and R. solanacearum with half-maximal effective concentration (EC50) values of 14.69 and 15.14 mu g/mL, respectively, which were even better than those of commercial agents Bismerthiazol and Thiodiazole Copper. In vivo antibacterial activities tests under greenhouse conditions revealed that the control efficiency of compound 4i against rice bacterial leaf blight and tobacco bacterial wilt were better than those of Bismerthiazol and Thiodiazole Copper. Meanwhile, field trials also indicated that compound 4i demonstrated appreciable control efficiency against rice bacterial leaf blight and tomato bacterial wilt. (C) 2014 Elsevier Ltd.
