Harnessing natural saponins: Advancements in mitochondrial dysfunction and therapeutic applications.

BACKGROUND

Mitochondrial dysfunction plays a crucial role in the development of a variety of diseases, notably neurodegenerative disorders, cardiovascular diseases, metabolic syndrome, and cancer. Natural saponins, which are intricate glycosides characterized by steroidal or triterpenoid structures, have attracted interest due to their diverse pharmacological benefits, including anti-inflammatory, antiviral, and anti-aging effects.

PURPOSE

This review synthesizes recent advancements in understanding mitochondrial dysfunction and explores how saponins can modulate mitochondrial function. It focuses on their potential applications in neuroprotection, cardiovascular health, and oncology.

STUDY DESIGN

The review incorporates a comprehensive literature analysis, highlighting the interplay between saponins and mitochondrial signaling pathways. Specific attention is given to the effects of saponins like ginsenoside Rg2 and 20(S)-protopanaxatriol on mitophagy and their neuroprotective, anti-aging, and synergistic therapeutic effects when combined.

METHODS

We conducted a comprehensive review of current research and clinical trials using PubMed, Google Scholar, and SciFinder databases. The search focused on saponins' role in mitochondrial function and their therapeutic effects, including "saponins", "mitochondria" and "mitochondrial function". The analysis primarily focused on articles published between 2011 and 2024.

RESULTS

The findings indicate that certain saponins can enhance mitophagy and modulate mitochondrial signaling pathways, showing promise in neuroprotection and anti-aging. Additionally, combinations of saponins have demonstrated synergistic effects in myocardial protection and cancer therapy, potentially improving therapeutic outcomes.

CONCLUSION

Although saponins exhibit significant potential in modulating mitochondrial functions and developing innovative therapeutic strategies, their clinical applications are constrained by low bioavailability. Rigorous clinical trials are essential to translate these findings into effective clinical therapies, ultimately improving patient outcomes through a deeper understanding of saponins' impact on mitochondrial function.
