摘要:

世界人口寿命的延长已导致神经退行性疾病的发病率显著增加,研究结果表明神经退行性疾病已经成为现代社会影响人们健康的主要因素。由于氧化应激是许多神经退行性疾病发生的根源,因此神经科学研究领域将发现新的潜在抗氧化剂治疗的工作放在了首要研究位置。事实上,虽然不同的神经退行性疾病出现在不同的神经元细胞内,但是氧化应激和抑制神经元存活是常见于许多病理当中的,因此这似乎是高度相关的治疗目标。越来越多的证据表明,在病理期, 几乎所有的神经退行性疾病都有一些共同病理期特性, 比如错误折叠蛋白质的积累和铁生成。文章主要关注一种抗氧化剂化合物-白藜芦醇,这是一种从植物内提取的芪家族的对称二苯代乙,具有抗真菌分子的潜在疗效。他们收集了许多关于白藜芦醇分子靶点的知识,试图解释或部分支持白藜芦醇作为神经退行性疾病治疗剂的有效性。在这种情况下, 采用药物与调节蛋白抗体配合治疗肯定会对阿尔茨海默病产生积极作用。此外, 白藜芦醇的活化作用与调节蛋白抗体表现也会对帕金森病有一定疗效,会防止突触核蛋白的积聚。最后,综合所有这些研究表明,白藜芦醇是一种治疗神经退行性疾病的新疗法,具有很强的科学支持。鉴于它不仅是活跃的自由基清除剂,还充当细胞存活与凋亡的调制器,因此,这种化合物可能有更大的潜在治疗效果, 而不是只有一种作用机制的药物。

Abstract:

In recent century, the advancing age and increased lifespan of the world’s population have led to a significant increase in the incidence of neurodegenerative diseases that are a major cause of disability and death for most of those affected. These findings put the neurodegeneration as a major public health problem in modern society also because effective pharmacological interventions for prevention and treatment of the disease, are lacking. Based on the premise that oxidative stress underlies a number of neurodegenerative diseases, the identification of novel antioxidants as potential therapeutics is a prolific area of neuroscience research. In fact, although the different neurodegenerative diseases manifest in distinct neuronal cell types, oxidative stress and suppression of neuronal survival signals are common to many of these pathological conditions and appear to be highly relevant targets for treatment. Growing evidences suggest that at the pathological level, almost all neurodegenerative diseases share common features such as the iron accumulation and the generation of misfolded protein deposits. Furthermore, it was shown that the oxidative stress markers precede the pathological lesions of neurodegeneration
