A visible light-initiated method has been developed for preparation of Se−S bond-containing peptides. The method is based on generation of sulfur-centered radical employing organic dye. The protocol is tolerant to unprotected peptides with “sensitive” amino acids. The stability of Se−S bond is evaluated in buffers at different pH (3.0–10.0) and also in the presence of oxidants and reducing agents.
已经开发了一种可见光引发的方法来制备含 Se-S 键的肽。该方法基于使用有机

硫为中心的自由基。该协议对具有“敏感”
氨基酸的未保护肽具有耐受性。Se-S 键的稳定性在不同 pH(3.0-10.0)的缓冲液中以及在氧化剂和还原剂的存在下进行评估。此外,Se-S 键在
生物相容性材料中作为氧化敏感接头的能力已得到证实。
