  摘要：

  S,S′-双-三苯甲基-N-BOC-1,2-乙二胺二硫醇（S,S′-bis-trityl-N-BOC-BAT）通过丙烯间隔基与2-硝基咪唑（NIM）结合，以提供一种潜在的锝-99m标记乏氧示踪剂的前体。为了进行锝-99m标记，开发了一种两步一锅法程序，包括在温和酸性条件下加热去保护配体，然后在SnCl2、酒石酸盐和99mTcO的存在下进行交换标记。标记反应混合物通过电喷雾放射性LC-MS进行分析，观察到的质谱与预测的oxo-Tc(V)-NIM-BAT结构相符。99mTc-NIM-BAT通过RP-HPLC纯化，并在正常小鼠中于10分钟和4小时后进行生物分布评估。99mTc-NIM-BAT主要通过肝胆排泄从血浆中清除。版权所有 © 2003 John Wiley & Sons, Ltd.
