sandwich‐type complexes formed between a cyclopeptide with alternating L‐proline and 6‐aminopicolinic acid subunits and inorganicanions can be stabilized by covalently linking a tris‐alkyne and a tris‐azide derivative of this peptide through copper‐catalyzed azide–alkyne cycloaddition. The resulting triply linked bis‐cyclopeptide can interact with anions such as sulfate ions in aqueoussolution by including
环肽与交替的L之间形成2:1三明治型复合物脯氨酸和6-氨基吡啶甲酸亚基和无机阴离子可通过铜催化的叠氮化物-炔烃环加成反应共价连接该肽的三炔和三叠氮化物衍生物来稳定。产生的三键连接的双环肽可以与阴离子如水溶液中的硫酸根离子发生相互作用,方法是将它们包含在两个环肽环之间的空腔中,在那里它们可以形成与内表面分布的酰胺NH基团的氢键。该系统的结合动力学与仅包含一个接头的双环肽的结合动力学显着不同,因为客体交换的速度相当慢。在热力学上,三联双环肽的硫酸盐配合物的稳定性接近H的log K a值为62 O /通道3OH 1:1(v / v),但是仅比柔韧性更高的单连接类似物的亲和力大大约一个数量级。滴定量热法表明,这种行为主要是由于连接子数量增加时,结合焓从放热变为吸热。NMR光谱和X射线晶体学的结果表明,单键和三键连接的双环肽在与硫酸根离子形成的络合物中采用相似的构象,但该络合物的形成在焓上对笼子不
