  Naphthyl and Coumarinyl Biarylpiperazine Derivatives as Highly Potent Human β-Secretase Inhibitors. Design, Synthesis, and Enzymatic BACE-1 and Cell Assays

  摘要：

  Twenty novel beta-secretase inhibitors containing biarylpiperazine moieties belonging to naphthyl and coumarinyl series were designed for their potential use in Alzheimer's disease therapy. Enzymatic and cell-based assays have been carried out. The biological results clearly demonstrate that specific substituents located at the N-4-position of the piperazine ring result in excellent in vitro inhibitory potency (IC50 values ranging between 40 and 70 nM). Variable temperature NMR and modeling studies are consistent with the obtained biological data, since these studies confirmed that introduction at the N-4-position of the piperazine ring allows productive interactions within the BACE-1 active site, which appear to be determinative for high BACE-1 inhibitory activity. These results are of particular interest since some of the new analogues belonging to the naphthyl series are almost one log more active than the best inhibitor of the similar family recently reported.

  The protease beta-secretase plays a central role in the synthesis of pathogenic amyloid-beta in Alzheimer's disease. Here, we report a new series of analogues based on the phenyl-piperazine scaffold coupled to various heterocyclic moieties, which demonstrate improved inhibitory activities on BACE-1 (FRET assay) compared to already known naphthyl counterparts. The obtained results suggest further structural modifications to access to more potent BACE-1 inhibitors. (C) 2006 Elsevier Ltd. All rights reserved.
