A rapid, simple and inexpensive synthesis of 5-radiohalogenated-2′-deoxyuridine from 5-trimethylstannyl-2′-deoxyuridine is described. The total reaction and purification time including thin layer chromatography (tlc) for quality control is less than 30 min. This method produces excellent yields (>95%) of 123I-, 125I-, 131I-UdR. The radiochemical purity of all tested preparations (>20) was determined to be greater than 99%. This new method is the basis of a radiolabeling kit/generator for preparation of radiohalogenated nucleosides. 2′-Deoxyuridine (UdR) halogenated with a stable isotope of bromine was also synthesized indicating that the method can be applied to the preparation of 5-radiobromo-2′-deoxyuridine (BUdR).
本研究描述了一种从 5-三甲基锡-2′-脱氧尿苷快速、简单和廉价合成 5-放射性卤代-2′-脱氧尿苷的方法。包括用于质量控制的薄层色谱法(tlc)在内,整个反应和纯化时间不到 30 分钟。该方法可获得产率极高(>95%)的 123I-、125I-、131I-UdR。所有测试制剂(大于 20 个)的放射化学纯度均大于 99%。这种新方法是制备放射性卤化核苷的放射性标记试剂盒/发生器的基础。用稳定的溴同位素卤化的 2′-脱氧尿苷(UdR)也被合成出来,表明该方法可用于制备 5-放射性溴-2′-脱氧尿苷(BUdR)。
