Minding metals: tailoring multifunctional chelating agents for neurodegenerative disease

Area of Science:

• Neuroscience
• Pharmacology
• Biochemistry

Background:

• Neurodegenerative diseases, including Alzheimer's and Parkinson's, are linked to increased oxidative stress due to elevated metal ions (iron, copper, zinc).
• Current therapeutic approaches often target single disease mechanisms, necessitating multifaceted strategies for complex neurodegenerative disorders.

Purpose of the Study:

• To review advances in multifunctional metal chelators as potential therapeutics for neurodegenerative diseases.
• To highlight chelators designed to overcome challenges in brain targeting and address multiple disease pathologies.

Main Methods:

• Focus on metal-chelating agents with additional therapeutic functionalities.
• Discussion of strategies to enhance blood-brain barrier penetration and metal selectivity.
• Exploration of agents with antioxidant, anti-amyloid, and enzyme-inhibiting properties.

Main Results:

• Multifunctional chelators offer a promising avenue for neurodegenerative disease treatment.
• These agents can simultaneously manage metal dyshomeostasis, oxidative stress, and other disease-specific factors.
• Advances include improved brain targeting and enhanced selectivity for disease-relevant metal ions.

Conclusions:

• Multifunctional metal chelators represent a next-generation therapeutic strategy for neurodegenerative diseases.
• These agents hold potential for ameliorating metal-associated damage and combating multifactorial disease progression.
• Further research into these advanced chelators could lead to more effective treatments for Alzheimer's and Parkinson's disease.
