excellent fungicidal activities, and the position of the substituents played an important role in fungicidal activities. Especially, compound 5n, exhibited better fungicidal activities than the commercial fungicide flutolanil against two tested fungi Valsa mali and Sclerotinia sclerotiorum, with EC50 values of 3.44 and 2.63 mg/L, respectively. And it also displayed good in vivo fungicidal activity against
为了寻找具有高生物活性的新的铅化合物,采用连接活性亚结构法设计了一系列N-取代的苯甲酰基-1,2,3,4-四氢喹啉基-1-羧酰胺。由取代的苯甲酸按四个步骤合成目标化合物,并通过1 H NMR,IR光谱和元素分析确定其结构。体外生物测定结果表明,某些目标化合物表现出优异的杀真菌活性,且取代基的位置在杀真菌活性中起重要作用。特别是,化合物5n对两种测试真菌Valsa mali和Sclerotionia sclerotiorum的杀真菌活性比市售杀真菌剂氟苯尼更好。,其EC 50值分别为3.44和2.63 mg / L。而且它还显示出良好的针对核盘菌的体内杀真菌活性,其EC 50值为29.52 mg / L。
