Abstract
Alzheimer’s Disease (AD) is the most common form of dementia, and is a multi-faceted disease that is characterized by oxidative stress, metal-ion dysregulation, and the formation of intracellular neurofibrillary tangles of tau protein and extracellular amyloid- (A) aggregates. This review will focus on the interaction of metal complexes with the A peptide, and how these interactions can modify the peptide aggregation pathway, oxidative stress, and overall toxicity of the A peptide. While certain endogenous metal complexes such as heme can enhance toxicity, a large number of reports detail the potentially protective effect of discrete metal complexes in AD. These results will be discussed in the context of ligand design to target specific peptide residues for covalent binding, modulate peptide aggregation towards non-toxic species, and enhance blood brain barrier access. Additional features of metal complexes such as light-activated A binding, catalytic antioxidant activity, and peptidase activity will be detailed.
