Myocardial ischemia is a high-risk disease among middle-aged and senior individuals. After thrombolytic therapy, heart tissue can potentially suffer further damage, which is called myocardial ischemia-reperfusion injury (MIRI). At present, the treatment methods and drugs for MIRI are scarce and cannot meet the current clinical needs. The mechanism of MIRI involves the interaction of multiple factors, and the current research hotspots mainly include oxidative stress, inflammation, calcium overload, energy metabolism disorders, pyroptosis, and ferroptosis. Traditional Chinese medicine (TCM) has multiple targets and few toxic side effects; clinical preparations containing C. A. Mey., (Burk.) F. H. Chen, L., cardioprotection, and other Chinese herbal medicines have been used to treat patients with coronary heart disease, angina pectoris, and other cardiovascular diseases. Studies have shown that saponins are the main active substances in TCMs containing C. A. Mey., (Burk.) F. H. Chen, L., and . In the present review, we sorted the saponin components with anti-MIRI effects and their regulatory mechanisms. Each saponin can play a cardioprotective role via multiple mechanisms, and the signaling pathways involved in different saponins are not the same. We found that more active saponins in C. A. Mey. are mainly dammar-type structures and have a strong regulatory effect on energy metabolism. The highly active saponin components of L. are oleanolic acid structures, which have significant regulatory effects on calcium homeostasis. Therefore, saponins in Chinese herbal medicine provide a broad application prospect for the development of highly effective and low-toxicity anti-MIRI drugs.
心肌缺血是中老年人中的一种高危疾病。溶栓治疗后,心脏组织可能会遭受进一步损伤,这被称为心肌缺血再灌注损伤(MIRI)。目前,针对MIRI的治疗方法和药物匮乏,无法满足当前临床需求。MIRI的机制涉及多种因素的相互作用,当前的研究热点主要包括氧化应激、炎症、钙超载、能量代谢紊乱、焦亡和铁死亡。中药具有多靶点且毒副作用少的特点;含有 C. A. Mey.、(Burk.) F. H. Chen、L.、具有心脏保护作用等的临床制剂已被用于治疗冠心病、心绞痛等心血管疾病患者。研究表明,皂苷是含有 C. A. Mey.、(Burk.) F. H. Chen、L.、和 的中药中的主要活性成分。在本综述中,我们梳理了具有抗MIRI作用的皂苷成分及其调控机制。每种皂苷可通过多种机制发挥心脏保护作用,不同皂苷涉及的信号通路不尽相同。我们发现, C. A. Mey. 中更多的活性皂苷主要为达玛烷型结构,对能量代谢具有较强的调控作用。L. 的高活性皂苷成分是齐墩果酸结构,对钙稳态具有显著调控作用。因此,中药中的皂苷为开发高效低毒的抗MIRI药物提供了广阔的应用前景。
