As cis/trans prolyl isomerization plays a crucial role in various biological processes, peptide mimics capable of modifying the cis/trans Xaa-Pro ratio are of particular interest. A practical approach toward proline derived triazolopeptides employing [3+2] azide–alkyne cycloadditions as the key reaction step and the analysis of their cis/trans prolyl ratios are reported. Structural investigations indicated
由于顺式/反式脯氨酸的异构化在各种生物学过程中都起着至关重要的作用,因此能够修饰顺式/反式Xaa-Pro比率的肽模拟物尤为重要。报道了一种使用[3 + 2]叠氮化物-炔烃环加成作为关键反应步骤的脯氨酸衍生的三唑类肽的实用方法,并分析了其顺式/反式脯氨酰基比率。结构研究表明顺式百分比和构象稳定性对分子内氢键作用的可调节性。
