Table 1_Natural products targeting mitochondrial homeostasis: a four-dimensional framework integrating dynamics, mitophagy, pharmacokinetics, and translational safety.pdf

Natural products have the potential for multi-target therapy, but insufficient understanding of their mechanisms of action and pharmacokinetic limitations hinder their clinical translation.</p>Objective<p>This review proposes a regulatory framework covering the four dimensions of biogenesis, morphology, quality control, and defense, aiming to systematically clarify how natural products regulate mitochondrial function and critically evaluate their translational potential.

The framework emphasizes that inter-organelle contact platforms, such as mitochondria–endoplasmic reticulum contact sites (MERCs) and mitochondrial–lysosomal contact sites (MLCs), are key sites through which natural products exert regulatory effects.</p>Methods<p>Major scientific databases, including PubMed, Web of Science, and Scopus, were searched, and evidence on mechanisms, pharmacokinetics, and toxicology from preclinical and clinical studies was comprehensively reviewed.</p>Results<p>Natural products can selectively regulate key mitochondrial pathways and regulatory nodes, including the AMPK/SIRT1/PGC-1α axis involved in mitochondrial biogenesis, the DRP1 axis involved in mitochondrial fission, and the PINK1/Parkin pathway involved in mitophagy.
