A series of novel quinazolinone acylhydrazone derivatives containing the indole moiety were designed, synthesized, and evaluated for their inhibition activities against some important phytopathogens in vitro. Antibacterial experiments indicated that some compounds exhibited remarkable inhibition activities against tested bacteria. Especially, the EC50 values of 7a (EC50 = 55.13 μg/mL against Xoo, EC50 = 56
设计,合成了一系列含有吲哚部分的新型喹唑啉酮酰基hydr衍生物,并评价了它们对某些重要植物病原菌的体外抑制活性。抗菌实验表明,某些化合物对被测细菌表现出显着的抑制活性。特别地,EC 50值7a中(EC 50 = 55.13针对微克/毫升白叶枯病,EC 50 = 56.92针对微克/毫升卢比)证实和最好的抗菌活性白叶枯病和卢比比其他化合物,并且控制剂叶枯唑(EC 50 = 89.80微克/反对毫升白叶枯病)和噻二唑铜(EC 50 = 189.52微克/毫升抗卢比),此外,化合物70(EC 50 = 50.80微克/毫升)中显示的优异的活性针对XAC比对照叶枯唑(EC 50 = 56.92μg/ mL)。
