Next-Generation Antioxidants in Cardiovascular Disease: Mechanistic Insights and Emerging Therapeutic Strategies

Area of Science:

• Cardiovascular research
• Redox biology
• Pharmacology

Background:

• Cardiovascular diseases (CVDs) are the leading global cause of death, linked to oxidative stress, endothelial dysfunction, inflammation, and atherothrombosis.
• Conventional antioxidant supplements (Vitamins C, E, beta-carotene) have shown limited clinical efficacy in human trials despite animal model success.
• A significant need exists for advanced, pharmaceutical-grade antioxidant therapies targeting specific disease mechanisms.

Purpose of the Study:

• To review novel antioxidant therapies for cardiovascular diseases.
• To assess the potential of next-generation antioxidants in modulating specific oxidative pathways.
• To explore how these therapies can inform personalized cardiovascular strategies.

Main Methods:

• Comprehensive review of current literature on oxidative stress and CVD.
• Assessment of emerging antioxidant modalities, including mitochondrial-targeted agents, NOX inhibitors, Nrf2 activators, nanoparticles, and gene-based strategies.
• Analysis of advancements in redox biology, nanotechnology, and metabolic regulation relevant to CVD.

Main Results:

• Next-generation antioxidants offer mechanistically targeted approaches to combat oxidative stress in CVD.
• Mitochondrial-targeted agents, NOX inhibitors, selenoprotein/Nrf2 activators, engineered nanoparticles, and RNA/gene-editing strategies show promise.
• These novel therapies have the potential to modulate specific oxidative pathways implicated in CVD pathogenesis.

Conclusions:

• Next-generation antioxidants represent a promising paradigm shift from traditional supplementation for CVD.
• These advanced therapies hold potential for personalized cardiovascular prevention and treatment.
• Further research and clinical translation are crucial for realizing the full benefits of these novel approaches.
