标题:新型抗菌抗真菌喹喔啉衍生物的合成
摘要:设计,合成了一系列喹喔啉衍生物,并对其作为抗植物病原细菌和真菌的抗菌剂进行了评价.其中一些化合物在体外表现出显着的抗菌和抗真菌活性.化合物5K对柑橘食酸菌( Ac ) 显示出非常好的抗菌活性.化合物5J和5T表现出最有效的抗rs (立枯丝核菌)活性,相应的ec 50值分别为8.54和12.01 μg Ml-1,优于商业嘧菌酯(26.17 μg Ml-1 ) .进一步,扫描电镜结果证明化合物5J对rs的细胞形态有一定的影响.此外,体内生物测定还表明,化合物5J的抗rs活性可以有效防治水稻纹枯病.这些结果表明喹喔啉衍生物可能是有前途的农业杀菌剂和杀真菌剂.
