approaches to the synthesis of 3′-azido-3′-deoxythymidine labelled with tritium in the heterocyclic base have been developed. With this aim, enzymatic transribosylation with [3H]thymine using the enzyme preparation from rat liver and a three-step chemical synthesis with use of the tritium labelled precursor were studies. The enzyme preparation did not catalyse the transfer of the 3′-azido-3′-deoxyribosyl
已经开发了合成在杂环碱基中用氚标记的 3'-azido-3'-deoxythymidine 的新方法。为此,研究了使用来自大鼠肝脏的酶制剂与 [3H] 胸腺嘧啶的酶促转核糖基化以及使用氚标记的前体进行的三步化学合成。酶制剂不催化 3'-叠氮基-3'-脱氧核糖基片段向 [3H] 胸腺嘧啶残基的转移。5'-O-Benzoyl-2,3'-anhydrothymidine 作为化学方法标记氚的前体。得到的[3H]3'-叠氮基-3'-脱氧胸苷的比放射性为18.3 Ci/mmol,氚位于胸腺嘧啶残基的C-6位。版权所有 © 2003 John Wiley & Sons, Ltd.
