Selenocystine ([Sec]2) and aryl-substituted selenocysteine (Sec) derivatives are synthesized, starting from commercially available amino acid L-serine. These compounds are characterized by a number of analytical techniques such as NMR (1H, 13C and 77Se) and TOF mass spectroscopy. This study reveals that the introduction of amino/imino substituents capable of interacting with selenium may stabilize the Sec derivatives. This study further suggests that the oxidation–elimination reactions in Sec derivatives could be used for the generation of biologically active selenols having internally stabilizing substituents.
从市售氨基酸 L-丝氨酸开始,合成了硒代半胱氨酸([Sec]2)和芳基取代的硒代半胱氨酸(Sec)衍生物。通过核磁共振(1H、13C 和 77Se)和 TOF 质谱等分析技术对这些化合物进行了表征。这项研究表明,引入能与硒相互作用的氨基/亚氨基取代基可以稳定 Sec 衍生物。这项研究进一步表明,Sec 衍生物中的氧化-消除反应可用于生成具有内部稳定取代基的生物活性硒醇。
