摘要
氧化应激（ｏｘｉｄａｔｉｖｅｓｔｒｅｓ）在中枢神经系统退行性疾病，如帕金森氏病、老年性痴呆和多发性硬化等的发病机制中起重要作用。这些疾病严重影响着老年人的生活质量，因此寻找有效的抗氧化剂用于防治中枢神经系统退行性疾病的发生和发展是一个十分重要和迫切的问题。本文研究了五味子酚（Ｓａｌ）、丹酚酸Ａ（ＳａｌＡ）和ＳＹＬ三种化合物对氧化应激损伤中枢神经细胞的保护作用及其作用机理。Ｓａｌ和ＳａｌＡ分别为中药红花、五味子和丹参的有效成分，ＳＹＬ是新的、全合成的化合物，三者均有显著的抗氧化活性。本文研究结果显示三种化合物在体内外对多种氧化应激损伤脑组织模型都具有明显的保护作用。
Oxidative stress may play an important role in neuronal degenerative diseases such as Parkinsons disease, Alzheimers disease, and amyotrophic lateral sclerosis. These disorders make the elderly not being able to live normally and move freely. So it is necessary to find effective antioxidants to prevent or cure the aged persons from diseases related to neuronal degeneration. Schisanhenol (Sal) and salvianolic acid A (Sal A) are known antioxidants which were isolated from Chinese herbs respectively. SYL is a totally synthetic new compound. The results showed that Sal, Sal A and SYL significantly protect cerebral cells from the injuries induced by oxidative stress.
