The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds of the formula R—Y—X—Z—R where each R denotes a triiodinated phenyl residue further substituted by hydrophilic moieties, Y and Z are urea and urethane groups and X is a alkylene group which may be further substituted. The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging, and to contrast media containing such compounds.
本发明涉及一类化合物及含有此类化合物的诊断组合物,其中所述化合物为公式R-Y-X-Z-R中含有
碘的化合物,其中每个R表示三
碘苯基残基进一步被亲
水基团取代,Y和Z为
尿素和
脲基团,X为可以进一步取代的烷基团。本发明还涉及将此类诊断组合物作为对比剂在诊断成像中的使用,特别是在X射线成像中的使用,以及含有此类化合物的对比介质。
