  用于放射免疫治疗应用的七齿双功能配体的方便合成和评估

  摘要：

  开发了一种用于抗体靶向放射免疫疗法 (RIT) 应用的双功能螯合剂 C-NE3TA-NCS 的有效合成路线。探索了以关键反应步骤为中心的各种合成方法，包括双分子环化、氮丙啶和氮丙啶阳离子的开环反应以及还原胺化，以优化四氮杂基螯合物 TANPA 和 C-NE3TA 类似物的制备。七齿 C-NE3TA-NCS 与肿瘤靶向抗体偶联，并与六齿 C-NOTA-NCS 进行比较，用于与镧系元素进行 RIT 的放射性标记反应动力学。与 C-NOTA 抗体偶联物相比，C-NE3TA 抗体偶联物与 90Y 的络合动力学显着增强。

  We report the synthesis and evaluation of an enantiomerically enriched bifunctional chelator, (S)-C-NE3TA. The bifunctional chelator was efficiently prepared by regioselective and stereoselective ring opening of an aziridinium ion. The new chiral chelator instantly and almost completely bound to 64Cu at room temperature. The corresponding 64Cu-radiolabeled complex remained intact in human serum for

  我们报告了对映体富集的双功能螯合剂 (S)-C-NE3TA 的合成和评估。通过氮丙啶离子的区域选择性和立体选择性开环有效地制备了双功能螯合剂。新的手性螯合剂在室温下立即几乎完全与 64Cu 结合。相应的 64Cu 放射性标记复合物在人血清中保持完整 48 小时，没有任何可测量的转螯合，并且可以耐受严格的 EDTA 挑战 24 小时。64Cu 放射性标记的 (S)-C-NE3TA 复合物在小鼠体内是稳定的，并产生了极好的生物分布特征。体外和体内评估的结果表明，新的光学活性螯合剂是 PET 成像应用的有希望的候选者。

  公开（公告）日：2009-06-18

  The present application discloses compositions and methods of synthesis and use of F-18 labeled molecules of use, for example, in PET imaging techniques. The labeled molecules may be peptides or proteins, although other types of molecules may be labeled by the described methods. Preferably, the F-18 may be conjugated to a targeting molecule by formation of a metal complex and binding of the F-18-metal complex to a chelating moiety. Alternatively, the metal may first be conjugated to the chelating group and subsequently the F-18 bound to the metal. In other embodiments, the F-18 labeled moiety may comprise a targetable construct used in combination with a bispecific or multi specific antibody to target F-18 to a disease-associated antigen, such as a tumor-associated antigen. The F-18 labeled targetable construct peptides are stable in serum at 37° C. for a sufficient time to perform PET imaging analysis.
