Acyl guanidines as beta-secretase inhibitors

摘要

There is provided a series of substituted acyl guanidines of Formula (I) or a stereoisomer; or a pharmaceutically acceptable salt thereof, wherein R₁, R₂, R₃, R₄ and R₅ as defined herein, their pharmaceutical compositions and methods of use. These compounds inhibit the processing of amyloid precursor protein (APP) by beta-secretase and, more specifically, inhibit the production of Abeta-peptide. The present disclosure is directed to compounds useful in the treatment of neurological disorders related to beta-amyloid production, such as Alzheimer's disease and other conditions affected by anti-amyloid activity.
