Cognitive-performance recovery of Alzheimer's disease model mice by modulation of early soluble amyloidal assemblies

Angew Chem Int Ed Engl. 2009;48(11):1981-6. doi: 10.1002/anie.200802123.

Abstract

A rationally designed oligomerization inhibitor interacts with early intermediate assemblies of amyloid-beta polypeptide (Abeta) through the aromatic elements and inhibits their assembly into the toxic oligomers that cause Alzheimer's disease by a unique C(alpha)-methylation beta-breakage strategy. The electrostatic potential of the low-energy conformation of the dipeptide inhibitor bound to Abeta is shown.
