The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing two linked iodinated phenyl groups of the general formula R—N(CO—CH

4
alkyl moieties optionally substituted by hydroxyl groups, by C

alkylamino groups, and wherein 2 or 3 carbon bridge elements together with alkyl or alkoxy groups form a cyclopentane, cyclohexane, pentahydropyran or tetrahydrofuran entity which may be alkyl- or hydroxyalkyl-substituted and each R denotes a triiodinated phenyl residue further substituted by hydrophilic moieties. 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和含有这些化合物的诊断组合物,其中这些化合物是含有碘的化合物。更具体地说,这些含碘化合物是化学化合物,包含两个连接的碘化苯基团,其通用式为R—N(CO—CH3)XN(CO—CH3)—R及其盐或光学活性异构体,其中X表示一种二价连接基,其中有5到10个碳、氧、硫和氮桥元素分隔乙酰化的氮原子,并且这些基团可能进一步被羟基基团、C1到C4烷基基团(可选择地被羟基基团取代)、C1到C4烷氧基团、氨基团和C1到C4烷基氨基团取代,其中2或3个碳桥元素与烷基或烷氧基团一起形成环戊烷、环己烷、五氢吡喃或四氢呋喃实体,该实体可能被烷基或羟基烷基取代,每个R表示进一步被亲水基团取代的三碘化苯基残基。该发明还涉及将这种诊断组合物用作对比剂进行诊断成像,特别是在X射线成像中,并涉及含有这种化合物的对比介质。
