This paper reports on new compounds, which consist of three functional parts — a transport fragment, a spacer and the biologically active compound. Cholic acid as transport fragment was linked via an alkyl spacer to a cisplatin analogue, representing the drug. The length of the alkyl chain was varied in order to investigate the influence of the distance between drug and transport fragment. Here we

Die Erfindung betrifft Verbindungen der allgemeinen Formel I
worin A gegebenenfalls eine funktionelle und / oder aktivierte Gruppe C für die Kopplung an sich selektiv anreichernde Verbindungen oder eine über die Gruppe C gekoppelte sich selektiv anreichernde Verbindung enthalten kann. B und B′ sind funktionelle Gruppen für die koordinative Bindung von Metallionen tragenden Gruppen. Die neuen Verbindungen dienen zur Komplexierung von radioaktiven Metallionen, insbesondere Rhenium- und Technetium-Isotopen, und werden in der medizinischen Diagnostik und Therapie eingesetzt.
本发明涉及通式 I 的化合物
其中 A 可选择性地含有官能团和/或活化基团 C,用于与选择性蓄积化合物或通过基团 C 偶联的选择性蓄积化合物偶联。B 和 B′为官能团,用于与携带金属离子的基团配位结合。新化合物可用于放射性金属离子,特别是铼和锝同位素的络合,并可用于医学诊断和治疗。

The synthesis of Costa-typeB12models 1 with a carbon bridge between the equatorial ligand and cobalt has been accomplished by condensation of butanedione monoxime and 2-(ω-functionalized)alkyl-1,3-diaminopropanes 8 followed by complexation with Co(II), introduction of a leaving group and intramolecular alkylation via Co(I) intermediates. The solution structure of intramolecularly alkylated Costa

The invention relates to compounds having the general formula I ##STR1## 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.
