This study aimed to synthesize some new sulfone derivatives containing a 1,3,4-oxadiazole moiety and investigate their in vitro antibacterial activities against Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas axonopodis pv. citri (Xac), the pathogens of rice bacterial leaf blight and citrus canker, respectively, by performing turbidimeter tests. Antibacterial bioassay results showed that compound
这项研究旨在合成一些含有1,3,4-恶二唑部分的新型砜衍生物,并研究其对米黄单胞菌的体外抗菌活性。米(Xoo)和黄单胞菌(Xanthomonas axonopodis)。citri(Xac)是水稻细菌性叶枯病和柑橘溃疡病的病原体,通过进行浊度计测试来确定。抗菌生物测定结果表明,化合物6d对Xoo和Xac具有出色的生物活性,有效浓度为50%(EC 50)值分别为thiodiazole铜(分别为121.82和77.04μg/ mL)和比美噻唑(分别为92.61和58.21μg/ mL)的0.17和1.98μg/ mL。同时,温室条件试验表明,与硫代二唑铜和比美噻唑相比,化合物6d可以更有效地减少水稻细菌性叶枯病。
