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 pharmaceutical composition for inhibiting amyloid beta peptide in a subject includes a compound having the formula (I):
where M is selected from a substituted or unsubstituted alkyl, halo, alkoxy, aryl, cyclic, or heterocyclic group;
p is an integer from 0-3;
X
