摘要:
The invention relates to hydroxypyridinone derivatives, their metal complexes, their preparation and their use for preparing conjugates with biomolecules. The conjugates are suitable as contrast agents in NMR diagnosis. A high relaxivity is achieved and the NMRD maximum is raised through a specific design of the ligands.

摘要:
The invention relates to polyrotaxanes that contain metal complexes or iodine-containing benzene derivatives as imaging components for MRT diagnosis and x-ray diagnosis.
摘要:
The invention relates to new metal complex-containing or iodine-containing benzene derivatives that contain pseudopolyrotaxanes. They are valuable compounds for diagnosis. The pseudopolyrotaxane complexes have general formula (I), in which n represents the numbers 6, 7 or 8; m represents the numbers 2 to 50; X represents a direct bond or the radical --O--CO--CH(CH.sub.3)--; R.sub.1 and Y have the meaning that is indicated in the description and represent R.sub.3 --Y--R.sub.4 polyalkylene glycols. ##STR1##
摘要:
The invention relates to new macrocyclic metal complex carboxylic acids of formula II ##STR1## whereby Z.sup.o stands for a metal ion equivalent of atomic numbers 58-71 andR stands for a CHX.sup.1 --CO--NH--CHY.sup.1 --(CH.sub.2).sub.f --COOH group, in which X.sup.1 and Y.sup.1, independently of one another, mean a hydrogen atom, a straight-chain or branched C.sub.1 -C.sub.7 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.
