The preparation of 99mTc-complexes with twenty derivatives of (2RS,4R)-1,3-thiazolidin-4-carboxylic acid over a broad pH range (1.5-8.9) is described for a potential use in radiodiagnostic medicine. The labelling efficiency was checked by paper and thin layer chromatography and for all well-soluble compounds is higher than 90 %. Paper electrophoresis and gel chromatography indicated the presence of two types of complexes differing in charge and molecular mass. The structure of both types of the 99mTc-complexes is also discussed. The organ distribution and its time dependence were determined in mice after i.v. application.
