Second generation of hydroxyethylamine BACE-1 inhibitors: optimizing potency and oral bioavailability

J Med Chem. 2008 Jun 12;51(11):3313-7. doi: 10.1021/jm800138h. Epub 2008 May 6.

Abstract

BACE-1 inhibition has the potential to provide a disease-modifying therapy for the treatment of Alzheimer's disease. Optimization of a first generation of BACE-1 inhibitors led to the discovery of novel hydroxyethylamines (HEAs) bearing a tricyclic nonprime side. These derivatives have nanomolar cell potency and are orally bioavailable.
