摘要
Solid-phase incorporation of diaminodiacids is one of the most effective approaches for synthesis of peptide disulfide bond mimics. One of a limitation of current diaminodiacid toolbox is that only four-atom linkage mimics are available that may not fully meet the activity optimization requirement. In this work, we developed a new diaminodiacid that contains a five-atom thioether (C-C-S-C-C) bridge for the first time. With this diaminodiacid in hand, we successfully obtained oxytocin containing new disulfide bond mimic by solid phase peptide synthesis. (C) 2019 Elsevier Ltd. All rights reserved.
