  4-Aminopyridine derivatives with antiamnesic activity

  摘要：

  Acetylcholine (Ach) enhancement, useful in the treatment of Alzheimer's disease (AD), may be obtained by means of ion channel modulators such as 4-aminopyridine (4-AP). 4-AP is also the central ring of tacrine, the first drug approved for the treatment of AD. The synthesis and pharmacological activity of three 4-AP derivatives, prepared with the aim of improving their antiamnesic activity, is here described. In two of these compounds 4-AP is connected to 4-aminobutyric acid (GABA), whereas in the third it is connected to 2-indolinone, i.e., the skeleton of linopirdine, another Ach enhancing agent. The new compounds showed potent antiamnesic activity in comparison with piracetam. (C) 2000 Edition scientifiques et medicales Elsevier SAS.

  硝基亚苄基丙二酸酯1-氧化物的重排。合成氨基吡啶衍生物的新方法

  摘要：

  氯化钛（IV）催化3-硝基-2-吡啶甲醛与丙二酸二乙酯之间的Knoevenagel缩合反应，得到3-硝基-2-吡啶基亚甲基丙二酸二乙酯，将其用过乙酸氧化，得到相应的1-氧化物。在伯醇和仲醇的存在下后者与二乙胺的反应导致硝基的还原和与吡啶环相连的乙烯基碳的氧化。丙二酸片段的同时迁移得到合适的3-氨基-2-吡啶羧酸酯。4-硝基-3-吡啶基亚甲基丙二酸酯1-氧化物重排成相应的4-氨基-3-吡啶羧酸酯类似物。
