Finding the best location: Improving the anti-amyloid ability of ruthenium(III) complexes with pyridine ligands.

Alzheimer's disease (AD) is a devastating neurological disorder where one of the primary pathological hallmarks are aggregate deposits of the peptide amyloid-beta (Aβ). Although the Food and Drug Administration (FDA) has recently approved therapeutics that specifically target Aβ, resulting in the removal of these deposits, the associated costs of such treatments create a need for effective, yet cheaper, alternatives. Metal-based compounds are propitious therapeutic candidates as they exploit the metal-binding properties of Aβ, forming stable interactions with the peptide, thereby limiting its aggregation and toxicity.
