different options, foldamers, which are sequence‐based oligomers with precise folded conformation, have emerged as a promising technology. We introduce oligoureafoldamers to reduce the peptide character of inhibitors of protein–protein interactions (PPI). However, the precise design of such mimics is currently limited by the lack of structural information on how these foldamers adapt to protein surfaces
Abstract Template-based stabilization of α-peptide helices with short accessory non-peptide helical foldamers fused either at the N- or C-terminus or at both ends of the peptide segment has been investigated by NMR spectroscopy in polar solvents and by X-ray diffraction. In this work, we focused on aliphatic N,N′-linked oligoureas that form predictable and well-defined helical structures akin to α-helices
摘要 已通过极性溶剂中的 NMR 光谱和 X 射线研究了基于模板的 α 肽螺旋稳定化,其具有在 N 或 C 末端融合或在肽段两端融合的短辅助非肽螺旋折叠体。衍射。在这项工作中,我们专注于脂肪族 N,N' 连接的低聚脲,它们形成类似于 α 螺旋的可预测且明确定义的螺旋结构。我们的结果表明,尿素寡聚体有能力强制肽段采用明确定义的α-螺旋结构,并且可能提出一种稳定短螺旋肽表位的通用方法,以开发蛋白质-蛋白质相互作用的调节剂。
