C(sp3)−H bonds, utilizing heavy water (D2O or T2O) as the hydrogen isotope source, and a guanidine base. This protocol has been successfully applied to the incorporation of deuterium in several amino acids (lysine, glycine and proline) and small peptides. Finally, the method has been applied to tritium, because tritium‐labelled peptides are essential for application in biological experiments, such as
氢同位素标记的化合物是药物研究和开发中必不可少的诊断工具,因为它们提供有关候选药物及其代谢物的生物代谢的重要信息。本文中,我们报告了光氧化还原引发的氢原子转移(HAT)协议,该协议利用重水(D 2 O或T 2)有效且选择性地在C(sp 3)-H键处引入氘或triO)作为氢同位素源和胍碱。该方案已成功应用于将氘掺入几种氨基酸(赖氨酸,甘氨酸和脯氨酸)和小肽中。最后,该方法已应用于tri,因为tri标记的肽对于生物实验(例如配体结合测定或吸收,分布,代谢和排泄(ADME)研究)的应用至关重要。
