  探索复杂分子后期甲基化的电化学 C(sp3)–H 氧化

  摘要：

  “神奇的甲基”效应，通过掺入单个甲基来显着提高生物活性化合物的效力，为药物化学家在药物发现过程中采用的简单而强大的策略提供了一种简单而强大的策略。尽管取得了重大进展，但能够对结构复杂的药物进行选择性 C(sp 3 )–H 甲基化的方法仍然非常有限。在这项工作中，我们公开了一种通过电化学氧化对受保护胺（即酰胺、氨基甲酸酯和磺酰胺）进行α-甲基化的模块化、高效和选择性策略。机理分析指导我们在经典的Shono氧化反应的基础上开发了一种改进的电化学方案，该反应具有反应范围广、官能团兼容性高、操作简单等特点。重要的是，该反应系统适合于药物活性剂中常见的含有碱性氮基团的复杂靶标的后期功能化。当与有机锌介导的 C-C 键形成相结合时，我们的方案能够实现多种胺衍生物的直接甲基化，包括那些先前已探索过的“神奇甲基”效应。因此，这种合成策略规避了目前获得此类化合物所必需的多步骤从头合成，并且有可能加速药物发现工作。

  Molecular Simplification of 1,4-Diazabicyclo[4.3.0]nonan-9-ones Gives Piperazine Derivatives That Maintain High Nootropic Activity

  摘要：

  Several 4-substituted 1-acylpiperazines, obtained by molecular simplification of 4-substituted 1,4-diazabicyclo[4.3.0]nonan-9-ones, have been synthesized and tested in vivo on the mouse passive avoidance test, to evaluate their nootropic activity. The results show that, apparently, an N-acylpiperazine group can mimic the 2-pyrrolidinone ring of 1,4-diazabicyclo[4.3.0]nonan-9-one, as the compounds of the new series maintain high nootropic activity. Moreover molecular simplification produces more clear-cut structure-activity relationships with respect to the parent series. The mechanism of action also appears to be similar in the two series. In fact, although the molecular mechanism remains to be elucidated, the most potent compound of each class (DM232 and 13, DM235) is able to increase acetylcholine release in rat brain. Piperazine derivatives represent a new class of nootropic drugs with an in vivo pharmacological profile very similar to that of piracetam, showing much higher potency with respect to the reference compound. Among the compounds studied, 13 (DM235) shows outstanding potency, being active at a dose of 0.001 mg kg(-1) sc.
