Abstract

Hydrophobic stearoyl derivatives of proline-containing di- and tripeptides and their deuterated analogs were synthesized. It was shown by NMR spectroscopy that cis-trans-equilibrium around an X-Pro peptide bond is displaced towards trans-conformers for compounds containing a Ste-Pro fragment as opposed to the compounds containing Boc-Pro or Gly-Pro fragments.

摘要

合成了含脯氨酸的二肽和三肽的疏水硬脂酰衍生物及其氘代类似物。核磁共振光谱表明,与含有Boc - Pro或Gly - Pro片段的化合物相比,含有Ste - Pro片段的化合物中,X - Pro肽键周围的顺反平衡向反式构象偏移。
