A novel class of .sup.123m Te-labeled steroids and amino acids is provided by the method of reacting a .sup.123m Te symmetric diorgano ditelluride with a hydride reducing agent and a source of alkali metal ions to form an alkali metal organo telluride. The alkali metal organo telluride is reacted with a primary halogenated steroidal side chain, amino acid, or amino acid precursor such as hydantoin. The novel compounds are useful as biological tracers and as organal imaging agents.
本发明提供了一种新型的.sup.123m Te标记的类固醇和氨基酸,其方法是通过将.sup.123m Te对称二有机基二碲与氢化还原剂和碱金属离子源反应,形成碱金属有机碲化物。然后将碱金属有机碲化物与主要卤代类固醇侧链、氨基酸或氨基酸前体(如乌头嘧啶)反应。这些新化合物可用作生物示踪剂和器官成像剂。
