A group of functionalized polyaminocarboxylate chelants that form complexes with rare earth-type metal ions are disclosed. The complexes, covalently attached to an antibody or antibody fragment, can be used for therapeutic and/or diagnostic purposes.

Macrocyclic ligands and complexes

Particle-emitting radionuclides, e.g. Gd-159, Ho-166, Lu-177 and Yb-175, have been complexed with organic aminoalkylenephosphonic acids. These complexes have been found useful in compositions for the therapeutic treatment of calcific tumors or the relief of bone pain in animals.

Organic amine phosphonic acid complexes for the treatment of calcific

Particle-emitting radionuclides, e.g. Gd-159, Ho-166, Lu-177 and Yb-175, have been complexed with organic aminoalkylenephosphonic acids wherein the nitrogen and phosphorus are interconnected by an alkylene group or substituted alkylene group. These complexes have been found useful in compositions for the therapeutic treatment of calcific tumors in animals and in relief of bone pain.

Radio labeled organic amine phosphonic acid complexes for the treatment

Particle-emitting radionuclides, e.g. Samarium-153, have been complexed with organic aminoalkylenephosphonic acids wherein the nitrogen and phosphorus are interconnected by an alkylene group or substituted alkylene group. These complexes have been found useful in compositions for the therapeutic treatment of calcific tumors in animals.

Organis amine phosphonic acid complexes for the treatment of calcific

Certain particle-emitting radionuclides, e.g. Samarium-153, have been complexed with certain alkylenepolyaminocarboxylic acid chelants. Compositions containing these complexes have been found useful in the treatment of calcific tumors in animals. The stability constant, log K, of the useful complexes is from about 14 to about 17 and the molar ratio of chelant to radionuclide in the compositions is such that the chelant is present in an amount sufficient to inhibit uptake of the radionuclide by soft tissue.

Radioactive compositions for the treatment of calcific tumors

The invention concerns a method for suppressing bone marrow which comprises administering at least one bone marrow suppressing radionuclide composition selected from the group of radionuclide compositions comprised of at least one of Samarium-153, Gadolinium-519, and Holmium-166 and at least one of ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid, hydroxyethylethylenediaminetrimethylenephosphonic acid, nitrilotrimethylenephosphonic acid and tris(2-aminoethyl)aminehexamethylenephosphonic acid, or a physiologically acceptable salt thereof.
