Cyclic peptides are capable of binding and modulating challenging drug targets including protein-protein interactions. However, their lack of membrane permeability prevents their application against intracellular targets. In this study, we show that it is possible to design a cell-permeable and biologically active cycloheptapeptide inhibitor against the intracellular enzyme peptidyl-prolyl isomerase Pin1 by integrating cell-penetrating and target-binding sequences.
环肽能够结合并调节具有挑战性的药物靶点,包括蛋白质-蛋白质相互作用。然而,它们缺乏膜通透性,这阻碍了它们用于对抗细胞内靶点。在本研究中,我们表明,通过整合细胞穿透序列和靶点结合序列,有可能设计出一种针对细胞内酶肽基脯氨酰异构酶Pin1的细胞可渗透且具有生物活性的环庚肽抑制剂。
