摘要:

文题释义:
表没食子儿茶素没食子酸酯:是一种来源于绿茶的天然多酚类化合物,具有广泛的生物活性和良好的生物相容性。表没食子儿茶素没食子酸酯具有显著的抗氧化、抗炎特性,在神经保护、心血管健康和代谢调节等领域展现出重要应用潜力。表没食子儿茶素没食子酸酯具有浓度依赖性的特性,在低浓度下发挥抗氧化作用,在高浓度或特殊微环境中展现促氧化能力,成为抗肿瘤、协同化疗等领域的重要研究对象。
活性氧:是细胞代谢过程中产生的一类具有高反应活性的氧化物,包括超氧阴离子、过氧化氢和羟基自由基等,在细胞信号传递、免疫防御和凋亡调控中具有重要作用。过量的活性氧会导致氧化应激,从而损伤细胞和组织,与多种疾病(如癌症、炎症性疾病和神经退行性疾病)的发生发展密切相关。因此,如何精准调控活性氧的生成与清除成为现代生物医学研究的热点。

背景:表没食子儿茶素没食子酸酯具有广泛的抗氧化和抗炎特性,在神经保护、心血管健康及代谢调节等领域展现出重要的应用潜力。近年来,负载表没食子儿茶素没食子酸酯的纳米材料在调控活性氧生成与清除的双向特性上受到关注,特别是在抗肿瘤、抗菌等领域的应用研究逐渐成为热点。
目的:系统综述表没食子儿茶素没食子酸酯在活性氧生成与清除中的作用机制,探讨负载表没食子儿茶素没食子酸酯纳米材料在抗氧化保护及抗肿瘤治疗中的潜在应用,分析未来发展方向与挑战。
方法:由第一作者检索PubMed、万方医学网及中国知网2009-2024年发表的相关文献,中文检索关键词为“表没食子儿茶素没食子酸酯,活性氧,抗氧化,促氧化,抗癌症,心血管疾病,骨缺损、纳米材料”,英文检索关键词为“Epigallocatechin gallate,reactive oxygen species,antioxidation,oxidation,anticancer,Angio cardiopathy,bone defect,nanomaterials”,最终筛选79篇高质量文献进行综述分析。
结果与结论:表没食子儿茶素没食子酸酯在低浓度或正常生理条件下表现出抗氧化特性,通过上调抗氧化酶(如超氧化物歧化酶和谷胱甘肽过氧化物酶)表达、抑制促氧化酶活性来保护正常细胞;在高浓度或特定微环境(如肿瘤细胞)中则展现出促氧化特性,通过促进活性氧生成诱导癌细胞凋亡或自噬。近年来,采用纳米载体、水凝胶及金属复合材料等技术显著提升了表没食子儿茶素没食子酸酯的稳定性、生物利用度及靶向释放效果,通过光动力治疗等手段进一步增强材料的促氧化能力。这种基于表没食子儿茶素没食子酸酯双向调控活性氧的机制为抗肿瘤、抗菌及抗氧化保护提供了重要策略,展现出广阔的应用前景与研究价值。

Abstract: BACKGROUND: Epigallocatechin gallate demonstrates extensive antioxidant and anti-inflammatory properties, positioning as a promising candidate for applications in neuroprotection, cardiovascular health, and metabolic regulation. In recent years, nanomaterials loaded with epigallocatechin gallate have garnered attention for their capacity to modulate the dual functions of reactive oxygen species generation and clearance, particularly within the realms of anti-tumor and antibacterial applications.
OBJECTIVE: To summarize the mechanisms by which epigallocatechin gallate generates and clears reactive oxygen species, explore the potential applications of epigallocatechin gallate-loaded nanomaterials in antioxidant protection and anti-tumor therapy and analyze future development directions and associated challenges.
METHODS: The first author searched for materials published between 2009 and 2024 using databases such as PubMed, WanFang, and CNKI. Chinese and English keywords used were “epigallocatechin gallate, reactive oxygen species, antioxidation, oxidation, anticancer, angiocardiopathy, bone defect, nanomaterials.” A total of 79 high-quality articles were selected for review and analysis.
RESULTS AND CONCLUSION: By upregulating antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase, while simultaneously suppressing the activity of pro-oxidative enzymes, epigallocatechin gallate exhibited antioxidant properties at low doses or under physiologically normal conditions. Conversely, at high concentrations or within specific microenvironments, such as those found in tumor cells, epigallocatechin gallate could exhibit pro-oxidant properties and stimulate the production of reactive oxygen species, leading to autophagy or cell death in cancer cells. Recent advancements have significantly enhanced the stability, bioavailability, and targeted distribution of epigallocatechin gallate through the use of nanocarriers, hydrogels, and metal composite materials. Furthermore, photodynamic therapy has been shown to amplify the pro-oxidative potential of epigallocatechin gallate. Given its broad range of potential applications and research significance, this dual regulatory mechanism of reactive oxygen species by epigallocatechin gallate presents a promising strategy for antibacterial therapies, cancer treatment, and antioxidant protection.
