Tritium-labeled nucleoside 5′-triphosphates (NTPs) nucleoside 5′-diphosphates (NDPs) containing the tritium label in positions 8 (in the purine nucleus) and 5 (in the pyrimidine nucleus) have been obtained by the dehalogenation of the corresponding bromine derivatives with gaseous tritium. The dehalogenation of the Br-NTPs and Br-NDPs was carried out at atmospheric pressure in an aqueous alkaline medium
氚标记的核苷 5'-三磷酸 (NTPs) 核苷 5'-二磷酸 (NDP) 在位置 8(在嘌呤核中)和 5(在嘧啶核中)含有氚标记,已通过相应溴的脱卤获得气态氚的衍生物。Br-NTPs 和 Br-NDPs 的脱卤是在大气压力下在碱性水性介质中使用钯催化剂(5% Pd/BaSO4 或 α-Pd)进行的。已经研究了在 5% Pd/BaSO4 存在下通过与气态氚的异质同位素交换反应将氚标记引入腺嘌呤系列核苷酸的可能性。对于合成的化合物,给出了用于色谱分离所需产物的洗脱液的组成。
