Progress toward the discovery and development of efficacious BACE inhibitors

BACE (beta-site amyloid precursor protein [APP] cleavage enzyme) is a transmembrane aspartyl protease responsible for the first cleavage event in the processing of APP to Abeta peptide. Amyloid plaques composed of Abeta peptides are hypothesized to be the root cause of neuronal cell death in Alzheimer's disease patients. Thus, BACE has become a target of significant interest for pharmaceutical and academic research. The recent literature relating to the discovery and development of efficacious BACE inhibitors is reviewed with particular emphasis on the patent literature.
