Spinal cord injury (SCI) is a severe traumatic condition that frequently results in various neurological disabilities, including significant sensory, motor, and autonomic dysfunctions. Ferroptosis, a recently identified non-apoptotic form of cell death, is characterized by the accumulation of reactive oxygen species (ROS), intracellular iron overload, and lipid peroxidation, ultimately culminating in cell death. Recent studies have demonstrated that ferroptosis plays a critical role in the pathophysiology of SCI, contributing significantly to neural cell demise. Three key cellular enzymatic antioxidants such as glutathione peroxidase 4 (GPX4), ferroptosis suppressor protein 1 (FSP1), and dihydroorotate dehydrogenase (DHODH), have been elucidated as crucial components in the defense against ferroptosis. Natural products, which are bioactive compounds mostly derived from plants, have garnered considerable attention for their potential therapeutic effects. Numerous studies have reported that several natural products can effectively mitigate neural cell death and alleviate SCI symptoms. This review summarizes fifteen natural products containing (-)-Epigallocatechin-3-gallate (EGCG), Proanthocyanidin, Carnosic acid, Astragaloside IV, Trehalose, 8-gingerol, Quercetin, Resveratrol, Albiflorin, Alpha-tocopherol, Celastrol, Hispolon, Dendrobium Nobile Polysaccharide, Silibinin, and Tetramethylpyrazine that have shown promise in treating SCI by inhibiting ferroptosis. Additionally, this review provides an overview of the mechanisms involved in these studies and proposes several perspectives to guide future research directions.
脊髓损伤(SCI)是一种严重的创伤性疾病,常常导致各种神经功能障碍,包括明显的感觉、运动和自主神经功能障碍。铁死亡是一种最近被发现的非凋亡形式的细胞死亡,其特征是活性氧(ROS)积累、细胞内铁过载和脂质过氧化,最终导致细胞死亡。最近的研究表明,铁死亡在SCI的病理生理学中起关键作用,对神经细胞死亡有重大影响。三种关键的细胞内酶抗氧化剂,如谷胱甘肽过氧化物酶4(GPX4)、铁死亡抑制蛋白1(FSP1)和二氢乳清酸脱氢酶(DHODH),已被阐明是抵御铁死亡的关键成分。天然产物大多是从植物中提取的生物活性化合物,因其潜在的治疗作用而备受关注。许多研究报告称,几种天然产物可以有效减轻神经细胞死亡并缓解SCI症状。本综述总结了十五种含有(-)-表没食子儿茶素-3-没食子酸酯(EGCG)、原花青素、肌醇六磷酸、黄芪甲苷IV、海藻糖、8-姜酚、槲皮素、白藜芦醇、白花芍药苷、α-生育酚、雷公藤红素、漆黄素、铁皮石斛多糖、水飞蓟宾和川芎嗪的天然产物,这些天然产物在通过抑制铁死亡治疗SCI方面显示出前景。此外,本综述概述了这些研究中涉及的机制,并提出了几个观点以指导未来的研究方向。
