involvement of individual and inter‐related pathological factors [i.e., amyloid‐β (Aβ), metals, and oxidative stress] in the pathogenesis of Alzheimer's disease (AD), chemical tools have been developed. Characteristics required for such tool construction, however, have not been clearly identified; thus, the optimization of available tools or new design has been limited. Here, key structural properties
为了阐明阿尔茨海默氏病(AD)发病机理中各个和相互关联的病理因素[即淀粉样β(Aβ),金属和氧化应激]的参与,已开发出化学工具。但是,这种工具构造所需的特性尚未明确。因此,可用工具或新设计的优化受到限制。在这里,报告了关键的结构特性和机制,可以确定具有AD中多种致病特征的工具的调节反应性。通过合理的结构选择和变异,在用于体外和体内金属-Aβ研究的工具框架上建立了一系列小分子。变化包括:(i)Aβ相互作用部分的位置和数量;(ii)金属结合位点;(iii)树立性和结构灵活性。详细的生化,生物物理和计算研究能够为如何建立分子式奠定基础,以设计出能够通过不同机制控制各种病理成分的反应性的化学工具。总的来说,这项多学科研究说明了针对这种复杂脑部疾病的工具发明的基于结构机理的策略。
