disulfide-rich peptides. In this study, we report a new diaminodiacid containing ethylene glycol bridge (EG-DADA), obtained primarily through the ring-opening addition reaction of aziridine derivatives with hydroxyl groups. The practicability and oxidation stability of this novel diaminodiacid have been illustrated by the synthesis of disulfide bond mimics of tachyplesin I and α-ImI. The development of EG-DADA
通过二氨基二酸策略用代谢稳定的等排物取代二硫键已被证明是提高富含二硫键的肽的稳定性的有效且灵活的方法。在这项研究中,我们报道了一种新的含有乙二醇桥的二氨基二酸 (EG-DADA),主要通过氮丙啶衍生物与羟基的开环加成反应获得。通过合成 tachyplesin I和α-ImI的二硫键模拟物,说明了这种新型二氨基二酸的实用性和氧化稳定性。EG-DADA的开发丰富了醚基二氨基二酸,为二硫化物替代肽的构建提供了灵活的选择。
