TECHNETIUM- AND RENIUM-CHELATE, DIAGNOSTIC AGENT CONTAINING SAME, MEDICINE CONTAINING SAME FOR THERAPY OF TUMOR, AND PREPARATION THEREOF

Compounds of the general formula I are capable of reducing pertechnetate to an oxidation level of less than +7 without an addition of reducing agents, forming, via the groups Y and Z, stable complexes with the technetium or rhenium isotopes which have been reduced in this manner, and, if appropriate...

Zusammenfassung:Compounds of the general formula I are capable of reducing pertechnetate to an oxidation level of less than +7 without an addition of reducing agents, forming, via the groups Y and Z, stable complexes with the technetium or rhenium isotopes which have been reduced in this manner, and, if appropriate, accumulating selectively in certain tissues or lesions due to a compound which is coupled with the aid of a functional group which is part of R . The technetium and rhenium complexes of the compounds of the general formula I, and their salts with organic and inorganic acids, can be employed in in-vivo diagnostics and in therapy, preferably in tumour therapy.
