The invention concerns novel multiple-substituent diethylenetriamine pentaacetic acid derivatives, their complexes and complex salts, containing an element with the atomic numbers 20 - 32, 39 - 51 or 57 - 83, pharmaceutical compositions containing these compounds, methods of preparing the compounds, the use of the compositions as contrast media and antidotes, and methods of preparing the pharmaceutical compositions.
摘要:
New dimer DTPA derivatives have the general formula (I) that consists of the increments (A) and (B) which are interconnected by one of the pairs of substituents R?1 and R1', R2 and R2', R15 and R15', R1 and R2', R1' and R2, R1' and R15, R1 and R15', R2 and R15', R2' and R15¿. The interconnecting substituent pairs stand for heterocycle, a phenylene residue, a C¿0?-C30-alkylene or C7-C30-aralkylene chain, which may be optionally substituted by 1-4 hydroxy, C1-C6-alkoxy, carboxy or mercapto groups and/or interrupted by 1 to 6 oxygen, nitrogen or sulphur atoms or sulfinyl and/or sulfonyl groups; Y stands for a hydrogen atom and/or a metal ion equivalent of an element having atomic numbers 21-32, 37-39, 42-51 and 57-83; and X and X' stand for a group -OY or -CONR?5R6¿. Also disclosed is the use of said metal complexes in NMR and/or röntgen diagnosis, in radiodiagnosis and radiotherapy, as well as a process for preparing the same.

摘要:
Iodine-containing dendrimer polymers have the general formula (I) A-(X)b, in which A stands for a hydrogenated core of index b, b being 1 to 8, X stands for a residue composed of (a) repetitive units S and maximum 2n image-generating residues Z, n determines the number of generations and is 1 to 10, and S and Z have different meanings. These polymers are precious X-ray diagnostic agents.
