The intersection of the amyloid cascade hypothesis and the implication of metal ions in Alzheimer disease progression has sparked an interest in using metal-binding compounds as potential therapeutic agents. In the present work, we describe a prochelator SWH that is enzymatically activated by β-secretase to produce a high affinity copper chelator CP. Because β-secretase is responsible for the amyloidogenic processing of the amyloid precursor protein, this prochelator strategy imparts disease specificity towards copper chelation not possible with general metal chelators. Furthermore, once activated, CP efficiently sequesters copper from amyloid-β, prevents and disassembles copper-induced amyloid-β aggregation, and diminishes copper-promoted reactive oxygen species formation.
