good inhibitors of acetylcholinesterase while being less active for butyrylcholinesterase. Activity of the compounds increased with the ring size of the heterocycle, and a maximum of activity was observed for an analog holding 12 methylene groups in the aliphatic side chain. These compounds may be regarded as promising candidates for the development of efficient inhibitors of acetylcholinesterase being
先前从长胡椒(Piper longum)中分离出的生物碱Piperlongumine B(19)首次以短序列和高收率与19个类似物进行了合成。在Ellman分析中对这些化合物的筛选显示,其中一些是乙酰胆碱酯酶的良好抑制剂,而对丁酰胆碱酯酶的活性较低。化合物的活性随杂环的环大小而增加,对于在脂族侧链中具有12个亚甲基的类似物,观察到最大的活性。这些化合物可被认为是开发可用于治疗阿尔茨海默氏病的有效乙酰胆碱酯酶抑制剂的有前途的候选者。
