摘要:
Diagnostic media suitable for NMR diagnoses contain compounds of Formula I ##STR1## wherein is a single bond or a double bond, X is the grouping --(CH.sub.2).sub.n -- or, if is a single bond, also the grouping --NHCO(CH.sub.2).sub.n -- wherein n means 0 to 4,m means the numbers 0, 1, or 2,R.sub.1 is an alkyl residue substituted by hydroxy groups, acyloxy groups and/or alkylidenedioxy groups,R.sub.2 has the same meanings as R.sub.1 or is a hydrogen atom or an alkyl residue,R.sub.3 and R.sub.4 are alkyl residues, andR.sub.5 and R.sub.6 are alkyl residues optionally substituted by hydroxy groups.

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 which optionally contains imino, phenylenoxy, phenylenimino, amido, hydrazido, ester group(s), oxygen, sulfur and/or nitrogen atom(s) and is substituted, if desired, by hydroxy, mercapto, imino, epoxy, oxo, thioxo and/or amino group(s), 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:
Fluorobenzenensulfonamides of Formula I ##STR1## wherein m means the number 0, 1, 2, 3, or 4,n means the number 0 or 1, andY means the residue of an aminocarboxylic or aminosulfonic acid,with the proviso that m and n are not to stand simultaneously for the number 0 and, if desired, the acid groups are present in the form of their amides or in the form of salts with organic or inorganic bases, are suitable for use as NMR diagnostic aids.
摘要:
2-Amino-1-(1,3-dioxolan-4-yl)ethanol compounds of formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and can be hydrogen or a lower alkyl group of 1-4 carbon atoms; or when R.sup.2 is an alkyl group of 1-4 carbon atoms, R.sup.1 can also be an alkoxy group of 1-4 carbon atoms; or R.sup.1 and R.sup.2 combined form an alkylene residue of 5 or 6 carbon atoms,are especially suited as intermediates in the production of opacifying compounds useful in X-ray contrast media.
