Cascade polymer complexes that contain
a) complexing ligands of general formula I
A-{X—[Y-(Z-(W—K
W
)
Z
)
y
]
x
} (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 and that for the product of the multiplicities,
16
≦a·x·y·z·w≦64
holds true,
b) at least 16 ions of an element of atomic numbers 20 to 29, 39, 42, 44 or 57-83,
c) optionally cations of inorganic and/or organic bases, amino acids or amino acid amides as well as
d) optionally acylated terminal amino groups
are valuable compounds for diagnosis and therapy.
含有以下成分的级联高分子复合物:
a) 通式IA-{X—[Y-(Z-(W—KW)Z)y]x} (I) 的络合配体,其中
A 代表一个碱基多重性为a的含氮级联核,X和Y分别独立地代表重复多重性为x或y的级联复制单元,Z和W独立地代表重复多重性为z或w的级联复制单元,K代表络合剂的基团,a代表数字2到12,x,y,z和w独立地代表数字1到4,前提是至少有两个复制单元不同,并且对于多重性的积,16≦a·x·y·z·w≦64成立,
b) 至少16个原子序数为20到29、39、42、44或57-83的元素离子,
c) 可选的无机和/或有机碱、氨基酸或氨基酸酰胺阳离子,以及
d) 可选的酰化末端氨基基团,
这些复合物对于诊断和治疗是有价值的化合物。
