Abstract:
The discovery that β-secretase is a membrane-anchored aspartic protease memapsin 2 has stimulated much interest in the design and testing of its inhibitors for the treatment of Alzheimer's disease. This article discusses the strategy for the development of such inhibitor drugs. Enzymology and structural determination tools have permitted the design of memapsin 2 inhibitors with high potency and in a size range possible for penetration of the blood-brain barrier. Transgenic Alzheimer's mice have been used to show that when memapsin 2 inhibitors are transported to the brain, they effectively reduce the production of amyloid β. Although development of a clinical candidate of memapsin 2 inhibitor drug remains a very challenging undertaking, the progress so far lends some optimism for future prospects.Keywords: Alzheimer's disease; β-secretase; memapsin 2; aspartic protease; inhibitor drugs
