| abstract |
The present invention relates to complexes of cascade polymers containing a / complex-forming ligands of the general formula I- {X- [Y- / Z- / WK.sub.wn / .sub.zn / .sub.yn] .sub.xn}. .an (I) in which A denotes a nitrogen containing cascade core of a basal multiplicity a, X and Y denote each other a direct bond or a cascade reproduction unit of multiplicity x, or y, Z and W respectively represent a cascade reproduction unit of reproduction multiplicity of, respectively w, K denotes the radical of the complexing agent, and denotes the number 2 to 12 and ax, y, zaw independently represent the numbers 1 to 4, with the proviso that at least two reproduction units are different and that the multiplicity of 16 is <=. and that at least one cascade reproduction unit X, Y, Z and W is a 1,4,7,10-tetraazacyclodecane or 1,4,8,11-tetraazacyclotetradecane reproduction unit, b / at least 16 ions of sequence number elements 20 to 29, 39, 42, 44 or 57 to 83, c / optionally cations of inorganic and / or organic bases, amino acids or amino acid amides and d / optionally acylated terminal amine o acids. These compounds are valuable compounds for diagnosis and therapy |
