CHELATE FORMING COMPOUNDS FOR FORMING COMPLEX COMPOUNDS WITH RADIOACTIVE ISOTOPES THEIR METAL COMPLEXES AND UTILIZATION OF THESE COMPOUNDS FOR DIAGNOSTIC AND THERAPICAL PURPOSES

摘要

The invention relates to compounds having the general formula I (* CHEMICAL STRUCTURE *) (I) where A if required can contain a functional and/or activated group C for coupling to selectively concentrating compounds or can contain a selectively concentrating compound coupled via the group C. B and B' are functional groups for coordinate bonding of groups carrying metal ions. The novel compounds are for forming complexes with radioactive metal ions, more particularly rhenium and technetium isotopes, and are used in medical diagnosis and therapy.
