Polyiodinated compounds, process for preparing them and diagnostic compositions

摘要

Polyiodinated benzene derivs. of formula (I) are new. In (I), R1-R6 are I or a gp. of formula (i)-(iii); A is absent or 1-4C alkylene, opt. substd. by OH; R7-R12 are H or 1-10C alkyl (opt. substd. by OH or 1-3C alkoxy (itself opt. substd. by OH)) or NR7R8, NR9R10 or NR11R12 may complete a satd. 5-8 membered heterocycle (opt. OH substd.); with the proviso that at least 4 of R1-R6 are I and that the molecule contains 10-24 OH gps.; all alkyl and alkoxy are linear or branched. Also new are aminoalcohols of formulae (A), formula (B) NHR-CH(CH2OH)-CH(OH)-CH2OH and formula (C) NHR'-CH(CH2OH)-(CH(OH))3-CH2OH where n is 1-3; R is CH2-(CHOH-)p-CH2OH; p is 2 or 3; R' is CH2-(CHOH)p'-CH2OH; and p' is 1-3.
