However, recent studies have uncovered an additional function of these natural flavonoids: their ability to inhibit ferroptosis. Ferroptosis is a key mechanism driving cell death in central nervous system (CNS) diseases, including both acute injuries and chronic neurodegenerative disorders, characterized by iron overload-induced lipid peroxidation and dysfunction of the antioxidant defense system. This review discusses the therapeutic potential of natural flavonoids from herbs and nutraceuticals as ferroptosis inhibitors in CNS diseases, focusing on their molecular mechanisms, summarizing findings from preclinical animal models, and providing insights for clinical translation. We specifically highlight natural flavonoids such as Baicalin, Baicalein, Chrysin, Vitexin, Galangin, Quercetin, Isoquercetin, Eriodictyol, Proanthocyanidin, (-)-epigallocatechin-3-gallate, Dihydromyricetin, Soybean Isoflavones, Calycosin, Icariside II, and Safflower Yellow, which have shown promising results in animal models of acute CNS injuries, including ischemic stroke, cerebral ischemia-reperfusion injury, intracerebral hemorrhage, subarachnoid hemorrhage, traumatic brain injury, and spinal cord injury. Among these, Baicalin and its precursor Baicalein stand out due to extensive research and favorable outcomes in acute injury models. Mechanistically, these flavonoids not only regulate the Nrf2/ARE pathway and activate GPX4/GSH-related antioxidant pathways but also modulate iron metabolism proteins, thereby alleviating iron overload and inhibiting ferroptosis. While flavonoids show promise as ferroptosis inhibitors for CNS diseases, especially in acute injury settings, further studies are needed to evaluate their efficacy, safety, pharmacokinetics, and blood-brain barrier penetration for clinical application.</p>","PeriodicalId":12491,"journal":{"name":"Frontiers in Pharmacology","volume":"16 ","pages":"1570069"},"PeriodicalIF":4.4,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11973303/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yiqi Qingre Gao (YQQRG) has shown potential in alleviating CKD, although its exact mechanism of action remains uncertain. This study aims to evaluate the impact of YQQRG on renal fibrosis and to explore the molecular pathways involved. <b>Methods:</b> The study employed a unilateral ureteral obstruction (UUO) mouse model, followed by a 2-week course of YQQRG treatment. Renal function was assessed through measurements of serum creatinine (SCr) and blood urea nitrogen (BUN). Kidneys were collected for histological and molecular biology analysis. To identify the detailed mechanisms, network pharmacology, RNA sequencing (RNA-Seq), transforming growth factor-beta1 (TGF-β1)-stimulated human renal proximal tubular epithelial (HK-2) cells, and molecular docking were used. <b>Results:</b> YQQRG treatment significantly improved renal function, pathological damage, and renal fibrosis in UUO mice. Ten blood-entering components and 403 potential targets of YQQRG were identified by liquid chromatography-mass spectrometry (LC-MS) and network pharmacology. 20,107 targets of renal fibrosis were revealed by RNA-Seq of kidneys from the control and UUO groups. The results of the KEGG pathway enrichment analysis of YQQRG and renal fibrosis were combined, which showed that YQQRG's renoprotective effects were strongly associated with the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway. Experimental validation further confirmed that YQQRG suppressed the PI3K/AKT pathway in the renal tissues of UUO mice; the addition of the PI3K/AKT agonist reversed the antifibrotic effects of YQQRG in TGF-β1-stimulated HK-2 cells. Furthermore, molecular docking indicated that YQQRG's primary active components exhibited a strong binding affinity to critical targets. <b>Discussion:</b> This study initially demonstrated that YQQRG improved renal function and kidney injury in UUO mice by revealing its antifibrotic mechanism, and it operates through the inhibition of the PI3K/AKT pathway, which highlights YQQRG as a potential therapeutic option for treating CKD.</p>","PeriodicalId":12491,"journal":{"name":"Frontiers in Pharmacology","volume":"16 ","pages":"1538061"},"PeriodicalIF":4.4,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11973907/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the PI3K/Akt/mTOR pathway plays a crucial role in the treatment of cardiovascular diseases, highlighting its dual significance in both oncology and cardiology. Therefore, the PI3K/Akt/mTOR pathway has become an ideal signaling pathway for studying cardioprotection, anticancer effects, and their associated cardiac toxicity. Botanical drugs have emerged as a significant source for developing therapeutic agents with anticancer and cardioprotective effects, often exhibiting bidirectional protective properties. Consequently, this study investigates the bidirectional regulatory influence of botanical drug metabolites in oncology and cardiology via the PI3K/Akt/mTOR pathway. The research indicated that the PI3K/Akt/mTOR signaling pathway plays a critical regulatory role in the pathogenesis of both tumors and cardiovascular diseases. The botanical drug metabolites Ruscogenin, Sulforaphane, Naringenin, Kaempferol, Poncirin, and Puerarin can improve cancer by inhibiting the phosphorylation levels within the PI3K/Akt/mTOR signaling cascade. Moreover, they also provide cardioprotective effects in cardiac injury conditions by activating the phosphorylation levels of the PI3K/Akt/mTOR pathway. Therefore, the phosphorylation dynamics of key components in the PI3K/Akt/mTOR pathway, particularly the phosphorylation of Akt, along with the functional implications of different phosphorylation sites, may offer new therapeutic strategies and insights for cancer treatment and the mitigation of cardiotoxicity associated with cancer therapies.</p>","PeriodicalId":12491,"journal":{"name":"Frontiers in Pharmacology","volume":"16 ","pages":"1467894"},"PeriodicalIF":4.4,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11973345/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
