Cascade polymer complexes, process for their production and pharmaceutical agents containing said complexes

摘要

Cascade polymer complexes that contain a) complexing ligands of general formula IA-{X-[Y-(Z-(W-Kw)z)y]x}a, (I) in which A 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, that 16
