Biological evaluation of 99mTc labelled cis-platinum containing benzyliminodiacetic acids as potential tumour imaging agents.
The synthesis of three new potential tumour-imaging radiopharmaceuticals in which a cis-platin derivative is attached to benzyl iminodiacetic acid, a ligand capable of forming a stable complex with 99mTc, has previously been reported by us [Awaluddin et al. Appl. Radiat. Isot. 38, 671-674 (1987)]. We have now carried out extensive biodistribution studies on these compounds as well as on two fragments of their structures which do not contain platinum. The results suggest that the presence of platinum is not essential for the tumour-localizing properties of the radiopharmaceuticals.
