Abstract
A group of functionalized amine chelants having ortho ligating functionality that form complexes with rare-earth type metal ions are disclosed. The complexes can be covalently attached to an antibody or antibody fragment and used for therapeutic and/or diagnostic purposes. In addition certain of the chelant-radionuclide complexes can be effectively employed in compositions useful as therapeutic and/or diagnostic agents for calcific tumors and/or relief of bone pain.
