  Novel coumarin-3-carboxamides bearing N-benzylpiperidine moiety as potent acetylcholinesterase inhibitors

  摘要：

  Some novel coumarin-3-carboxamide derivatives linked to N-benzylpiperidine scaffold were synthesized and evaluated as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors. The screening results showed that most of compounds exhibited potent anti-AChE activity in the range of nM concentrations. Among them, compound 10c bearing an N-ethylcarboxamide linker and a 6-nitro substituent showed the most potent activity (IC50 = 0.3 nM) and the highest selectivity (SI = 26,300). Compound 10c was 46-fold more potent than standard drug donepezil against AChE. The kinetic study revealed that compound 10c exhibited mixed-type inhibition against AChE. Protein-ligand docking study demonstrated that the target compounds have dual binding site interaction mode and these results are in agreement with kinetic study. (C) 2013 Elsevier Masson SAS.

  摘要：

  功能团互变是实现合成的基本化学过程。在这份报告中，我们描述了一种将烯基丙二腈转化为一步制备的初级醇的策略。该反应依赖于经过精心设计的氧化还原过程，涉及烯基丙烯还原、丙二腈氧化和酰氰还原，其中分子氧和NaBH4共同发挥作用。这种方法已应用于各种碳骨架，并用于合成复杂的萜类结构。

  Via Knoevenagel condensation of N-benzyl-4-piperidone with malononitrile some new 4-substituted N-benzyl-piperidines have been prepared. By means of these transformations an economic and large-scale synthesis of biologically important intermediate N-benzyl-piperidine-4-ethanol has been elaborated.
