摘要:
The invention relates to the use of perfluoroalkyl-containing metal complexes that have a critical micelle formation concentration 1 nm and a proton relaxivity in plasma (R1)>10 l/mmol·s as contrast media in MR imaging for visualization of intravascular thrombi.
摘要:
Oligomeric compounds that contain perfluoroalkyl of general formula IA--R.sup.F (I)in whichA is a molecule portion that contains 2-6 metal complexes that are connected directly or via a linker to a nitrogen atom of an annular skeleton chain, andR.sup.F is a perfluorinated, straight-chain or branched carbon chain with formula --C.sub.n F.sub.2n E, in which E represents a terminal fluorine, chlorine, bromine, iodine, or hydrogen atom and n stands for numbers 4-30,are valuable compounds for diagnosis, especially as in-vivo contrast media.
摘要:
The invention relates to a process for the production of diethylenetriaminepentacarboxylic acid tetraesters of general formula I ##STR1## in which R.sup.1 and Z have different meanings.
摘要:
The invention relates to intermediate products and a new process for the production of benzocycloheptene C. The process for the production of its new intermediate products according to the invention starts from economical starting materials, provides the intermediate stages in high yields and high purity, without chromatographic purification steps, and allows production on an industrial scale.
