Abstract: | The preparation of99mTc-complexes with nine derivatives of (4R)-1,3-thiazolidine-4-carboxylic acid over a broad pH range is described. The labeling efficiency of all compounds was checked by paper- and thin layer chromatography. Paper electrophoresis and gel chromatography indicated the presence of two types of99mTc-complexes differing in charge and molecular size. Preliminary results of the biodistribution of anionic complexes in mice are given. The structure of both types of the Tc-complexes is also discussed. |
