This study is the first to demonstrate that shizukaol D, a natural compound isolated from Chloranthusjaponicus, 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.
这项研究首次表明,从金粟兰属植物中分离得到的天然化合物石竹烯 D 可以激活 AMP 激活的蛋白激酶(AMPK),这是细胞内能量代谢的关键传感器和调节剂,导致 HepG2 细胞中的甘油三酯和胆固醇水平降低。此外,我们发现石竹烯 D 通过去极化线粒体膜和抑制能量产生来诱导线粒体功能障碍,这可能导致 AMPK 激活。我们的研究结果提供了线粒体功能障碍和 AMPK 激活之间的可能联系,并表明石竹烯 D 可能用于治疗代谢综合征。
