This process is closely linked to the onset and progression of various heart diseases. Modern pharmacological research has demonstrated that phytochemicals can regulate mitochondrial homeostasis in cardiomyocytes through multiple mechanisms, influencing mitophagy and protecting cardiomyocytes, which in turn exerts anti-cardiovascular effects. However, the underlying mechanisms of these effects are not yet fully understood. This study summarizes the pharmacological effects and molecular mechanisms of mitophagy in heart diseases, aiming to provide reference for the research and treatment of phytochemicals targeting mitophagy against heart diseases. The results indicated that phytochemicals (such as Berberine, Ginsenoside Rg1, Quercetin, Resveratrol, Baicalein, and so on) can exert preventive and therapeutic effects on heart diseases (such as cardiac toxicity or damage, myocardial ischemia/reperfusion injury, heart failure, heart aging, cardiac hypertrophy, cardiomyopathy, and so on.) via regulating the PINK1/Parkin and FUNDC1-dependent mitophagy pathway. These compounds mainly exert their effects by regulating mitochondrial homeostasis, mitochondrial dynamics, mitochondrial oxidative stress, mitochondrial apoptosis, and mitochondrial energy metabolism.

Flavonoids, a diverse class of bioactive polyphenolic compounds found in plant-derived foods and beverages, have garnered increasing attention as potential therapeutic agents for improving metabolic health. This review provides a comprehensive analysis of the therapeutic effects of flavonoids in the context of the MetS, with a particular focus on their modulation of the AMP-activated protein kinase (AMPK) pathway. AMPK serves as a central regulator of cellular energy balance, glucose metabolism, and lipid homeostasis, making it a critical target for metabolic intervention. Through a systematic review of the literature up to April 2024, preclinical studies across various flavonoid subclasses, including flavonols, and flavan-3-ols, were analysed to elucidate their mechanistic roles in metabolic regulation. Many studies suggests that flavonoids enhance glycolipid metabolism by facilitating glucose transporter 4 (GLUT4) translocation and activating the AMPK pathway, thereby improving glycemic control in diabetes models. In obesity-related studies, flavonoids demonstrated significant inhibitory effects on lipid synthesis, reduced adipogenesis, and attenuated proinflammatory cytokine secretion via AMPK activation. These findings show the broad therapeutic potential of flavonoids in addressing the MetS and its associated disorders. While these preclinical insights highlight flavonoids as promising natural agents for metabolic health improvement, it is important to note that their excessive concentrations may disrupt these pathways, potentially leading to metabolic imbalance and cytotoxicity. Further studies and clinical trials are essential to determine optimal dosing regimens, formulations, and the long-term safety and efficacy of flavonoids. This review highlights the importance of flavonoids for natural interventions targeting MetS and its comorbidities, offering a foundation for future translational research.</p>","PeriodicalId":20110,"journal":{"name":"Phytotherapy Research","volume":" ","pages":"1403-1421"},"PeriodicalIF":6.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142953071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, ASK showed minimum inhibitory concentration of 1-2 μg/mL against MRSA. Mechanistic investigations revealed that ASK operates through a multifaceted antibacterial mechanism. First, ASK disrupts bacterial membrane integrity and dissipates proton motive force by targeting membrane phospholipids. Further analysis demonstrated a significant reduction in oxygen consumption and ATP production, indicative of respiratory chain inhibition. Additionally, ASK interferes with bacterial cell wall synthesis, as evidenced by reduction of peptidoglycan precursors and downregulated expression of genes involved in peptidoglycan synthesis.
