  Synthesis and Biological Evaluation of Analogues of a Novel Inhibitor of β-Amyloid Secretion

  摘要：

  A drug library of 17200 compounds was screened to select small molecules that inhibit the secretion of amyloid beta peptide (Am, the major component of Alzheimer disease senile plaques, from a human neuronal cell line. Twenty-nine hits were validated that decreased A beta secretion by >40% at 10 mu M, for a 0.17% hit rate. A lead hit was selected for further study based on its activity and low cytotoxicity, and it was found to inhibit A beta secretion through activation of the alpha-secretase pathway. Twenty-four commercially available and 53 synthesized analogues were analyzed for activity. Selected analogues were evaluated for biological stability by incubation with hepatoma cells and for transcellular permeability using Caco-2 cell monolayers. The analogue with the best permeability was evaluated in 2-month old amyloid precursor protein transgenic mice and found to acutely reduce cerebral A beta levels by 40% after a single iv administration.

  A new strategy for the synthesis of β-benzylmercaptoethylamine derivatives

  摘要：

  Here, we describe a new experimental approach to the synthesis of the beta-benzylmercaptoethylamine functionality, and illustrate its synthetic utility in multi-component reactions. Although prevalent in modern organic synthesis, no general methods have been described for this functionality. Using a carefully developed LiOH-water-ethanol reaction mixture, we were able to produce a diverse collection of beta-benzylmercaptoethylamines containing a range of sensitive functional groups in excellent yields. To further illustrate their utility in molecular library synthesis, we also report the use of beta-benzylmercaptoethylamines in five different multi-component reactions. (C) 2009 Elsevier Ltd.
