Chalcones containing tertiary amine side-chains have potent activity as acetylcholinesterase (AChE) inhibitors. However, the effects of the location of the tertiary amine groups as well as of other groups on AChE and butyrylcholinesterase (BChE) activity have not been reported. Here, we report the synthesis and testing of 36 new coumarin–chalcone hybrids (5d–7j, 9d–11f, 12k–13m) against AChE and BChE
含有叔胺侧链的查耳酮具有有效的乙酰胆碱酯酶(AChE)抑制剂活性。但是,尚未报道叔胺基团以及其他基团的位置对AChE和丁酰胆碱酯酶(BChE)活性的影响。在这里,我们报告了针对AChE和BChE的36种新香豆素-查耳酮杂种的合成和测试(5d – 7j,9d – 11f,12k – 13m)。查尔酮取代基的性质和位置对抑制活性以及对AChE的选择性超过BChE都有重要影响。与化合物对其中取代基为胆碱样的取代的查耳酮片段具有对AChE的有效活性而对BChE的活性较弱,而邻位取代的类似物表现出相反的作用。用酰胺,烷基或烯基取代末端胺基可消除活性。化合物5e表现出强大的抑制活性\((\ hbox IC} _ 50} = 0.15 \ pm 0.01 \,\ upmu \ hbox mol} /} \ hbox L} \))且对AChE的选择性优于BChE (比率27.4),动力学研究表明
