摘　　要：为了发现结构新颖的脱落酸功能类似物,以小分子abscisic mimic 1 (AM1)和Pyrabactin为先导化合物,运用活性亚结构拼接原理设计了喹啉-6-磺酰胺类化合物3和4.以廉价易得的喹啉为起始原料,经成盐、氧化、去芳香化、磺酰化、胺化5步反应,合成了11个未见文献报道的新型类似物.种子萌芽试验结果表明,浓度为50μmol·L^(-1)时10个化合物明显抑制了大豆种子发芽,降低浓度至25μmol·L时仍有4个化合物完全抑制萌芽,其活性与AM1相当,并且优于脱落酸.该结果有利于发现高活性的新型脱落酸功能类似物.To develop novel abscisic acid(ABA) functional mimics, a series of quinoline-6-sulfonamide compounds 3 and 4was designed based on the principle of active substructure splicing with ABA mimic 1(AM1) and pyrabactin as lead compounds. The low-cost and commercial quinoline was used as starting material to offer the novel compounds via the salifying,oxidation, hydrogenation, sulfonylation, amination. Additionally, all the target compounds could inhibit soybean seed germination at the concentration of 50 μmol·L^(-1). Furthermore, the compounds 3, 4b, 4h, 4i could inhibit soybean seed germination overwhelmingly at 25 μmol·L^(-1). These results are benefit to discovering novel and high activity of ABA functional mimics.
