Excess production of reactive oxygen species in the brain has been implicated as a common underlying risk factor for the pathogenesis of a number of neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), and stroke. In recent years, there is considerable interest concerning investigation of antioxidative and anti-inflammatory effects of phenolic compounds from different botanical sources. In this review, we first describe oxidative mechanisms associated with stroke, AD, and PD, and subsequently, we place emphasis on recent studies implicating neuroprotective effects of resveratrol, a polyphenolic compound derived from grapes and red wine. These studies show that the beneficial effects of resveratrol are not only limited to its antioxidant and anti-inflammatory action but also include activation of sirtuin 1 (SIRT1) and vitagenes, which can prevent the deleterious effects triggered by oxidative stress. In fact, SIRT1 activation by resveratrol is gaining importance in the development of innovative treatment strategies for stroke and other neurodegenerative disorders. The goal here is to provide a better understanding of the mode of action of resveratrol and its possible use as a potential therapeutic agent to ameliorate stroke damage as well as other age-related neurodegenerative disorders.
过量的活性氧在大脑中的产生被认为是多种神经退行性疾病(包括阿尔茨海默病(AD)、帕金森病(PD)和中风)发病机制的共同潜在风险因素。近年来,人们对从不同植物来源的酚类化合物的抗氧化和抗炎作用的研究产生了浓厚的兴趣。在这篇综述中,我们首先描述了与中风、AD 和 PD 相关的氧化机制,随后,我们重点介绍了最近的研究,这些研究表明白藜芦醇(一种来源于葡萄和红酒的多酚化合物)具有神经保护作用。这些研究表明,白藜芦醇的有益作用不仅限于其抗氧化和抗炎作用,还包括激活 SIRT1(沉默信息调节因子 2 相关酶 1)和维生素基因,从而可以预防氧化应激引发的有害作用。事实上,白藜芦醇对 SIRT1 的激活在开发中风和其他神经退行性疾病的创新治疗策略方面越来越受到重视。这里的目标是更好地了解白藜芦醇的作用模式及其作为潜在治疗剂改善中风损伤以及其他与年龄相关的神经退行性疾病的可能用途。
