Copper(I) targeting in the Alzheimer's disease context: a first example using the biocompatible PTA ligand.

Copper(I) coordinating ligands in the Alzheimer's disease context have remained unexplored, despite the biological relevance of this redox state of the copper ion. Here, we show that the PTA ligand can remove copper from Aß, prevent reactive oxygen species production and oligomer formation, two deleterious events in the disease's etiology.
