Deciphering the Power of Resveratrol in Mitophagy: From Molecular Mechanisms to Therapeutic Applications.

Resveratrol (RES), a natural polyphenolic compound, has garnered significant attention for its therapeutic potential in various pathological conditions. This review explores how RES modulates mitophagy-the selective autophagic degradation of mitochondria essential for maintaining cellular homeostasis. RES promotes the initiation and execution of mitophagy by enhancing PINK1/Parkin-mediated mitochondrial clearance, reducing reactive oxygen species production, and mitigating apoptosis, thereby preserving mitochondrial integrity. Additionally, RES regulates mitophagy through the activation of key molecular targets such as AMP-activated protein kinase (AMPK), the mechanistic target of rapamycin (mTOR), deacetylases (SIRT1 and SIRT3), and mitochondrial quality control (MQC) pathways, demonstrating substantial therapeutic effects in multiple disease models. We provide a detailed account of the biosynthetic pathways, pharmacokinetics, and metabolic characteristics of RES, focusing on its role in mitophagy modulation and implications for medical applications. Potential adverse effects associated with its clinical use are also discussed. Despite its promising therapeutic properties, the clinical application of RES is limited by issues of bioavailability and pharmacokinetic profiles. Future research should concentrate on enhancing RES bioavailability and developing derivatives that precisely modulate mitophagy, thereby unlocking new avenues for disease therapy.
