A new approach to non-covalent peptide-based nanotubular or rod-like structures is presented, whereby the monomeric units are preorganised into a β-strand geometry that templates the formation of an extended and unusual parallel β-sheet rod-like structure. The conformational constraint is introduced by Huisgen cycloaddition to give a triazole-based macrocycle, with the resulting self-assembled structures stabilized by a well-defined series of intermolecular hydrogen bonds.
本文介绍了一种构建非共价键肽基纳米管或棒状结构的新方法,其中单体单元预先组织成β-发夹几何形状,模板化形成一种扩展且不寻常的平行β-折叠棒状结构。通过胡伊斯滕环加成反应引入构象约束,得到基于三唑的大环,其自组装结构通过一系列明确的分子间氢键得到稳定。
