Abstract
Complexes of bicyclopolyazamacrocyclophosphonic acid compounds with a metal ion, e.g. .sup.153 Sm, .sup.177 Lu, .sup.159 Gd, .sup.149 Pm, .sup.140 La, .sup.175 Yb, .sup.166 Ho, .sup.90 Y, .sup.47 Sc, .sup.186 Re, .sup.188 Re, .sup.142 Pr, .sup.99m Tc, .sup.67 Ga, .sup.68 Ga, .sup.105 Rh, .sup.97 Ru, .sup.111 In, .sup.113m In or .sup.115m In ion, are disclosed. The complexes can be covalently attached to a biologically active molecule, e.g. an antibody or antibody fragment, to form conjugates. The complexes and conjugates are useful as radiopharmaceutical agents for therapy and/or diagnostic purposes.
