In vivo identification of the pharmacodynamic ingredients of Polygonum cuspidatum for remedying the mitochondria to alleviate metabolic dysfunction–associated fatty liver disease
Metabolic dysfunction–associated fatty liver disease (MAFLD) is a chronic liver disease that currently lacks approved pharmacological treatment options. The mechanisms and active ingredients of Polygonum cuspidatum (PC) that regulate the mitochondria to relieve MAFLD have not been assessed. Thus, this study was designed to explore the bioactive components of PC extract in regulating mitochondria to alleviate high-fat diet–induced MAFLD using mitochondrial pharmacology and pharmacochemistry. Our results demonstrate that PC protected the mitochondrial ultrastructure and inhibited oxidative stress and energy metabolism disorder in the liver mitochondria. Furthermore, PC-derived components in the liver mitochondria attenuated oxidative stress and restored the energy metabolism of fat emulsion–induced steatosis in L02 cell. Sixteen compounds were identified in the liver–mitochondrial extracts of PC-treated rats. The antisteatotic effects of three identified monomers and anti-MAFLD ability of the monomer group were confirmed. Collectively, our data suggest that the extract of PC can alleviate lipid metabolism disorder in MAFLD by protecting the mitochondrial ultrastructure, reducing oxidative stress injury, and promoting energy metabolism. The sixteen identified compounds were potentially the main effective ingredients of PC in treating MAFLD. Thus, PC shows potential in treating MAFLD and related mitochondrial dysfunction. The proposed strategy to identify the ingredients of herbal medicines based on mitochondrial pharmacology and pharmacochemistry presents a new approach in exploring the pharmacodynamic components of herbal medicines that regulate mitochondria in preventing and treating diseases.
