针对铜基放射性药物开发了一种新型交桥cyclam螯合剂CB-TE1K1P,该螯合剂可以在温和条件下以高比活度进行(64)Cu标记。合成 DBCO-PEG4-CB-TE1K1P 用于与蛋白质缀合,而合成 Dde-CB-TE1K1P((t)Bu2)-OH 用于固相肽合成。给出了各自的结合化学、放射性标记和血清稳定性的例子。
A new cross-bridged cyclam chelator, CB-TE1K1P, was developed for copper-based radiopharmaceuticals, and this chelator can be labelled with (64)Cu under mild conditions in high specific activity. DBCO-PEG4-CB-TE1K1P was synthesized for conjugation to proteins, while Dde-CB-TE1K1P((t)Bu2)-OH was synthesized for solid-phase peptide synthesis. Examples of the conjugation chemistry, radiolabelling and serum stability of each are presented.
