项目摘要
Cysteine residues located in clefts within the proteins are sterically restrained from forming inter- or intramolecular bridging bonds. The reactive intermediates generated by their reactions with reactive oxygen and nitrogen species play a crucial role in redox regulation. However, many of these intermediates are notoriously unstable in artificial systems, and model studies on these species have been difficult due to their instability. In this study, novel nano-sized molecular cavities with bowl-shaped frameworks were developed for modeling such sterically isolated environment and applied for the stabilization of highly reactive chemical species involved in redox regulations. Some of the mechanisms proposed for biological transformations were demonstrated experimentally by utilizing these model systems.
位于蛋白质裂隙中的半胱氨酸残基受到空间限制,无法形成分子间或分子内桥键。它们与活性氧和氮反应产生的活性中间体在氧化还原调节中起着至关重要的作用。然而,许多这些中间体在人工系统中非常不稳定,并且由于它们的不稳定性,对这些物种的模型研究一直很困难。在这项研究中,开发了具有碗形框架的新型纳米分子腔,用于模拟这种空间隔离的环境,并应用于稳定参与氧化还原调节的高反应性化学物质。利用这些模型系统通过实验证明了一些为生物转化提出的机制。
