摘要:
Polymeric compounds of general formula I(M).sub.n A (I)in whichM stands for the radical of a macrocyclic complexing agent,A stands for a backbone molecule, which shows a deficit of n amino groups, n hydroxy groups or n carboxy groups,n stands for the numbers 1 to 400, characterized in thatM, independent of one another, stands for complexing agents of general formula IA ##STR1## in which all variables are defined herein.
摘要:
The invention relates to macrocyclic metal complexes and their production and use for the production of conjugates with biomolecules. The conjugates are suitable as contrast media in NMR diagnosis and radiodiagnosis as well as for radiotherapy. High relaxivity is achieved by a special liganding of macrocyclic compounds, and a fine-tuning of the relaxivity is made possible.
摘要:
1. Compounds of general Formula I ##STR1## wherein n and m in each case mean the numbers 0, 1, 2, 3 and 4, X stands for a hydrogen atom and/or a metal ion equivalent of an element of atomic numbers 21-29, 31, 32, 37-39, 42-44, 49 or 57-83, R.sup.1 and R.sup.2, being different, mean in each case a hydrogen atom or a straight-chain, branched, saturated or unsaturated C.sub.0 -C.sub.20 -alkylene group, this alkylene group exhibiting at the end either a second molecule of general Formula I.sub.A or I.sub.B ##STR2## a functional group, or, linked by way of this functional group, a bio- or macromolecule, are valuable diagnostic and therapeutic media,
摘要:
The invention relates to complex compound as well as their salts consisting of at least one metal ion and one complexing agent of general formula I ##STR1## in which Z.sup.1, Z.sup.2 and s have different meanings, as well as their use for the production of agents for radiation therapy and for NMR diagnosis and diagnostic radiology, especially for contrasting the hepatobiliary system. Further, the invention relates to a process for the production of these compounds and agents.
摘要:
