Shizukaol D Isolated from Chloranthus japonicas Inhibits AMPK-Dependent Lipid Content in Hepatic Cells by Inducing Mitochondrial Dysfunction

摘要

This study is the first to demonstrate that shizukaol D, a natural compound isolated from Chloranthus japonicus , can activate AMP- activated protein kinase (AMPK), a key sensor and regulator of intracellular energy metabolism, leading to a decrease in triglyceride and cholesterol levels in HepG2 cells. Furthermore, we found that shizukaol D induces mitochondrial dysfunction by depolarizing the mitochondrial membrane and suppressing energy production, which may result in AMPK activation. Our results provide a possible link between mitochondrial dysfunction and AMPK activation and suggest that shizukaol D might be used to treat metabolic syndrome.
