A new cross-bridged cyclam chelator, CB-TE1K1P, was developed for copper-based radiopharmaceuticals, and this chelator can be labelled with 64Cu under mild conditions in high specific activity. DBCO–PEG4–CB-TE1K1P was synthesized for conjugation to proteins, while Dde–CB-TE1K1P(tBu2)–OH was synthesized for solid-phase peptide synthesis. Examples of the conjugation chemistry, radiolabelling and serum stability of each are presented.
