Fullerenes as Anti-Aging Antioxidants

Area of Science:

• Nanotechnology
• Biochemistry
• Pharmacology

Background:

• Fullerenes, discovered in 1985, are carbon allotropes with unique properties.
• Literature reports diverse biological effects of fullerenes, including both toxicity and therapeutic potential.
• Antioxidant and anti-aging actions are key areas of investigation for fullerene derivatives.

Purpose of the Study:

• To review the biological effects of fullerenes, emphasizing their antioxidant and anti-aging capabilities.
• To analyze experimental and theoretical data on buckminsterfullerene (C60) and its derivatives.
• To explore the potential of fullerenes as mitochondria protonophores and their implications for biological systems.

Main Methods:

• Comprehensive literature review of studies published up to 2016.
• Analysis of theoretical modeling and simulations of fullerene transport across lipid bilayers.
• Evaluation of experimental data on fullerene interactions with biological systems, including mitochondria.

Main Results:

• Fullerenes demonstrate potent antioxidant activity, primarily through scavenging reactive oxygen species.
• Theoretical modeling suggests fullerenes can act as protonophores, potentially uncoupling mitochondrial respiration.
• Simulations show fullerene derivatives can cross lipid membranes, supporting their biological accessibility.

Conclusions:

• Fullerenes possess significant antioxidant and anti-aging potential, linked to their mitochondrial interactions.
• Further research into fullerene toxicity and therapeutic applications is warranted.
• Fullerenes represent a promising class of nanomaterials for biomedical applications.
