GALENIC FORMULATIONS CONTAINING PARAMAGNETIC AND DIAMAGNETIC COMPOUNDS

摘要

Galenic formulations (A) contain paramagnetic perfluoroalkylated compounds (I) and diamagnetic perfluoroalkylated compounds (II). (II) include new cyclodextrin complexes (B). Galenic formulations (A) contain paramagnetic perfluoroalkylated compounds of formula Rf-A (I) and diamagnetic perfluoroalkylated compounds of formula Rf-L1-B2 (II). Rf = 4-30C perfluoroalkyl; A = molecular component containing 1-6 metal complexes; L1 = linker; B2 = hydrophilic group. Independent claims are also included for: (1) preparation of (A); and (2) new conjugates (B) comprising alpha-, beta- or gamma-cyclodextrin and perfluoroalkyl compounds of formula A1-L'-R' (III). A1 = adamantane, biphenyl or anthracene molecule; L' = linker consisting of a 1-20C linear hydrocarbyl chain (optionally interrupted by one or more O, one or more CO, SO2, CONH NHCO, CONR, NRCO, NH or NR or one piperazine); R' = 1-5C alkyl.
