title: Bis(thiosemicarbazones) as bifunctional chelators for the room temperature 64-copper labeling of peptides.
abstract: A range of new carboxylate functionalised bis(thiosemicarbazone) ligands and their Cu(II) complexes have been prepared, fully characterised and radiolabeled in high yield with both (64)Cu and (99m)Tc. Conjugation to a bombesin derivative was achieved using standard solid phase synthetic methodologies and the (64)Cu-labeled conjugate was shown to have good tumour uptake in mice with xenografted PC-3 tumours.
