  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.

  in synthesis. General methods for their preparation typically afford α and β disubstitution patterns or β only. Molecules with only α-substituents (β-hydrogen) are much less well-known. A chemoselective reductive tautomerization of α-cyanoacetates, using DIBAL-H, has been developed to access these valuable synthons. α,β-Unsaturated cyanoacetates and α-cyanoketones can, also, be selectively reduced via
