The invention relates to novel cascade polymer complexes, to compositions comprising these compounds, to the use of the complexes in NMR diagnosis, and to processes for preparing these compounds and compositions. The complex-forming cascade polymer complexes according to the invention can be described by general formula I:
R-L-A-X—[Y-(Z-W—K

a−1
(I)
where
R=is an HSA-binding unit,
L=is a linker or a bond,
A=is a nitrogen-containing cascade core of base multiplicity a,
X and Y are independently of one another a direct linkage or a cascade reproduction unit of reproduction multiplicity x and y, respectively,
Z and W=are independently of one another a direct linkage or a cascade reproduction unit of reproduction multiplicity z and w, respectively,
K is the residue of a complexing agent,
a=is numbers 2 to 12, and
x, y, z and w are independently of one another the numbers 1 to 4,
with the proviso that exactly one multiplicity of the base multiplicity a of the cascade core A represents exactly one point of linkage to L, and
with the proviso that the cascade polymer complexes comprise in the complexing agent residue K in total at least 4 ions of an element of atomic number 20 to 29, 39, 42 to 44 or 57 to 83 and comprise where appropriate cations of inorganic and/or organic bases, amino acids or amino amides.
该发明涉及新型级联聚合物复合物,包括这些化合物的组成,以及在核磁共振诊断中使用这些复合物的方法,以及制备这些化合物和组成物的过程。根据该发明,级联聚合物复合物可以用通用公式I描述:R-L-A-X—[Y-(Z-W—Kw}z)y]x}a−1(I),其中R=HSA结合单元,L=连接物或键,A=含氮级联核心,基数为a,X和Y分别是直接连接或再生单位,再生次数分别为x和y,Z和W分别是直接连接或再生单位,再生次数分别为z和w,K是络合剂残基,a为2至12之间的数字,x、y、z和w分别是1到4之间的数字,但级联核心A的基数a的一个复数恰好表示与L的连接点,级联聚合物复合物包含在络合剂残基K中总共至少4个原子序数为20至29、39、42至44或57至83的元素离子,并包括必要时的无机和/或有机碱、氨基酸或氨基酰基的阳离子。
