    摘要: The present invention relates to a polyamine-substituted ligand for the preparation of a contrast agent derived from a chelating molecule selected from the group consisting of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) and diethylentriamine-pentaacetic acid (DTPA), wherein at least one of the carboxylic groups of the chelating molecule is reacted with an amine of formula HNR1R2 to form an amide bond, wherein R1, R2 are independently selected from the group consisting of H; (CH2)n—NR3R4; and R5; R3, R4 are independently selected from the group consisting of H; (CH2)m—NR6R7; and (CH2)m-1—CH3; R6, R7 are independently selected from the group consisting of H; and (CH2)o-1—CH3; n, m, o are independently 2, 3, or 4; R5 is of formula and optionally at least one of the carboxylic groups of the chelating molecule is further reacted with a monoalkylamine having 1 to 18 carbon atoms to form an amide bond; provided that at least one of R1, R2 is other than H. Furthermore, the invention relates to contrast agents for magnetic resonance imaging (MRI) comprising said ligands and in-vivo diagnostic methods based on MRI using said contrast agents.
