Phytochemical small molecules from Stauntonia chinensis DC as multi-target modulators: molecular mechanisms and therapeutic potential.

Stauntonia chinensis is a medicinal vine used in East Asian traditional medicine and is rich in saponins and triterpenoids with putative multi-target activities. Pre-clinical studies have reported that these compounds exert anti-inflammatory, antioxidant, neuroprotective, and anticancer effects. Evidence supporting these effects are mostly originated from heterogeneous in vitro, in vivo, and computational studies, which have reported modulation of signaling pathways, such as nuclear factor-κB (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2), and phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathways. Despite these encouraging findings, clinical translation remains limited. Major barriers include poor oral bioavailability, rapid pharmacokinetics, hemolytic effects, and variability in extract standardization. This review evaluates whether phytochemical small molecules derived from Stauntonia chinensis DC exhibit mechanistically coherent and experimentally substantiated multi-target molecular actions. To this end, phytochemical characterization, mechanistic evidence, pharmacokinetics, toxicity, formulation, and translational considerations are systematically integrated to provide a translational roadmap for S. chinensis-derived compound, bridging traditional use with potential clinical applications in complex diseases. Furthermore, sophisticated delivery systems such as liposomes, nanoparticles, and phytosomes, and the rational structural optimization to enhance safety and pharmacokinetics are discussed.
