    摘要: Compounds of a general Formula I ##STR1## wherein Z.sup.1 and Z.sup.2 in each case independently mean the residue --(CH.sub.2).sub.m --(C.sub.6 H.sub.4).sub.q --(O).sub.k --(CH.sub.2).sub.n --(C.sub.6 H.sub.4).sub.1 --(O).sub.r --R, wherein m and n means the numbers 0-20, k, l, q and r means the numbers 0 and 1, and R means a hydrogen atom, an optionally OR.sup.1 -substituted C.sub.1 -C.sub.6 -alkyl residue, or a CH.sub.2 COOR.sup.1 group with R.sup.1 meaning a hydrogen atom, a C.sub.1 -C.sub.6 -alkyl residue, or a benzyl group, X means a hydrogen atom and/or a metal ion equivalent of an element of atomic number 21-29, 42, 44 or 57-83, with the provisos that at least two the substituents X stand for a metal ion equivalent; that one of the substituents Z.sup.1 and Z.sup.2 stands for a hydrogen and the other is not H; that--if n and 1 each mean the number 0--k and r do not simultaneously mean the number 1; that --(O).sub.r --R is not --OH; and that Z.sup.1 and Z.sup.2 are not --CH.sub.2 --C.sub.6 H.sub.4 --O--CH.sub.2 --COOCH.sub.2 C.sub.6 H.sub.5 or --CH.sub.2 --C.sub.6 H.sub.4 --O--(CH.sub.2).sub.5 --COOCH.sub.2 C.sub.6 H.sub.5, as well as their salts with inorganic and/or organic bases, amino acids or amino acid amides, are valuable pharmaceutical agents, e.g., for NMR or X-ray imaging.

    摘要翻译: 其中Z 1和Z 2在每种情况下独立地表示残基 - (CH 2)m - (C 6 H 4)q - (O)k - (CH 2)n - (C 6 H 4)1 - (C 1 -C 6) O)r R,其中m和n表示数字0-20,k,l,q和r表示数字0和1,R表示氢原子,任选OR 1取代的C 1 -C 6烷基残基或 CH2COOR1基团,其中R1表示氢原子,C1-C6烷基残基或苄基,X表示原子序数21-29,42,44或57-的元素的氢原子和/或金属离子当量, 83,条件是至少两个取代基X代表金属离子当量; 取代基Z1和Z2之一代表氢,而另一个不是H; 如果n和1每个意味着数字0-k,r不同时表示数字1; - (O)r-R不是-OH; 并且Z1和Z2不是-CH2-C6H4-O-CH2-COOCH2C6H5或-CH2-C6H4-O-(CH2)5-COOCH2C6H5,以及它们与无机和/或有机碱,氨基酸或氨基酸的盐 酰胺,是有价值的药剂,例如用于NMR或X射线成像。
