| abstract |
The invention pertains to novel compounds of general formula (I) in which M stands for a radioisotope of Tc or Re, L stands for a ligand of general formula (II) in which R?1, R2, R3, R4, R5 and R6¿ can have different meanings and stand for groups which are suitable both for the coordinate bonding of metal ions and for coupling to selectively self-concentrating compounds. The novel compounds are used to form complexes of technetium and rhenium and are used in medical diagnostics and therapy. |
