The invention provides an improved method of macrocyclization of peptidomimetics, as measured by isolated yields and product distribution, which comprises substitution of one or more of the backbone amide C=O bonds with a turn-inducing motif. The method is general with enhancements seen across a range of ring sizes (e.g. tri-, tetra-, penta- and hexapeptides). Specifically, the invention provides a peptidomimetic macrocycle comprising a carbonyl bioisosteric turn-inducing element having the structure: (I) wherein X is a heteroatom; and wherein R1 to R6 are each independently selected from alkyl, aryl, heteroaryl and H.
该发明提供了一种改进的肽类类似物的大环化方法,通过孤立产量和产物分布来衡量,其中包括用诱导转向基团替代一个或多个骨架酰胺C=O键。该方法是通用的,在一系列环大小(例如三肽、四肽、五肽和六肽)中均可见到增强效果。具体而言,该发明提供了一种包含具有结构的羰基
生物等同体诱导转向元素的肽类类似物大环:(I)其中X是杂原子;其中R1至R6分别独立地选自烷基、芳基、杂芳基和氢。
