摘要:The invention relates to novel macrocyclic metal complex carboxylic acids of formula (II), wherein Z DEG means a metal iron equivalent of atomic numbers 58-71 and R is a CHX<1>-CO-NH-CHY<1>-(CH2)f-COOH group, wherein X<1> and Y<1> mean individually a hydrogen atom, a straight-chained or branched C1-C7-alkyl radical, a phenyl or benzyl group and f means the figures 0-9. Said acids can be used as intermediate preparations for synthesis of cascade polymer complexes suitable as diagnostic agents.

摘要:The invention relates to new macrocyclic metal complex carboxylic acids of formula II whereby Zo stands for a metal ion equivalent of atomic numbers 58-71 and R stands for a CHX1-CO-NH-CHY1-(CH2)f-COOH group, in which X1 and Y1, independently of one another, mean a hydrogen atom, a straight-chain or branched C1-C7 alkyl radical, a phenyl or benzyl group and f means numbers 0 to 9. They can be used as intermediate stages for synthesis of cascade polymer complexes that are suitable as diagnostic agents.
