we report the synthesis, X-ray structure determination, and conformational analysis of a novel class of heteroatom-modified peptidomimetics, which we shall call “oxyazapeptides”. Substituting the typical native N-Cα bond with an O-Nα bond creates a completely new, previously unknown family of peptidomimetics, which are hydrolytically stable and display very interesting conformational behavior.

在本文中,我们报告了一类新型的杂原子修饰的拟肽模拟物的合成,X射线结构测定和构象分析,我们将其称为“氧杂肽”。代典型的原生NC α与债券α债券创建一个全新的,以前未知的家族肽,它们是水解稳定和显示非常有趣的构象的行为。力场计算表明,屏障围绕ON旋转α在oxyazapeptides键比NN周围低五倍α氮杂肽中的键。此外,X射线支持的构象分析表明,氧杂氮杂部分可以有效诱导β转角,这可以使新发现的氧杂氮杂肽支架成为药物发现和生物制剂设计的有用工具。
