Cascade polymer complexes containinga) complexing ligands of general formula I in whichA stands for a nitrogen-containing cascade nucleus of base multiplicity a,X and Y, independently of one another, stand for a direct bond or a cascade reproduction unit of reproduction multiplicity x or y,Z and W, independently of one another, stand for a cascade reproduction unit of reproduction multiplicity z or w,K stands for the radical of a complexing agent,a stands for numbers 2 to 12,x, y, z and w, independently of one another, stand for numbers 1 to 4,provided that at least two reproduction units are different and thatholds true for the product of the multiplicities,b) at least 16 ions of an element of atomic numbers 20 to 29, 39, 42, 44 or 57-83 andc) optionally cations of inorganic and/or organic bases, amino acids or amino acid amides are valuable compounds for diagnosis and therapy. |
