new capsule based on a β-sheet self-assembling cyclic peptide with the ability to recognize and release several guests is described. The host structure is composed of two self-complementary α,γ-cyclic peptides bearing a Zn porphyrin cap that is used for the selective recognition of the guest. The two components are linked through two dynamic covalent bonds. The combination of binding forces, including
描述了一种基于 β-折叠自组装环肽的新胶囊,具有识别和释放多个客人的能力。主体结构由两个带有锌卟啉帽的自互补 α,γ-环肽组成,用于选择性识别客体。这两个组件通过两个动态共价键连接。结合力的结合,包括氢键、金属配位和动态腙键,可以可逆地识别长联吡啶客体。对这些配体的亲和力显示出对客体长度的强烈依赖性。可以通过腙水解破坏夹心复合结构来实现封装配体的递送。
