Definitions
- the invention relates to novel ion pairs consisting of ionic metal complexes and halogenated compounds as counterions, methods for producing such ion pairs and their use in diagnostics and therapy.
- Contrast agents are indispensable aids in modern diagnostics; many diseases cannot be diagnosed without the use of contrast media. Contrast agents can be found in all areas of diagnostics such as X-ray, radio or ultrasound diagnostics or magnetic resonance imaging use.
- Contrast media are generally only suitable for one of the diagnostic methods described above, but not for several at the same time. Exceptions to this are the metal complexes described in WO 93/16375 or WO 97/1359, which are linked to iodine-substituted aromatics via amide bonds. With only one application of the contrast agent, these compounds should allow both NMR and X-ray examinations to be carried out. In many cases, a combination of the two imaging methods is advantageous for a differentiated display and a reliable diagnosis of certain diseases. These compounds are said to be particularly suitable for angiography.

und ihre Verwendung als Kontrastmitteland their use as a contrast medium
Die Erfindung betrifft neuartige lonenpaare, bestehend aus ionischen Metallkomplexen und halogenierten Verbindungen als Gegenionen, Verfahren zur Herstellung solcher lonenpaare und deren Verwendung in der Diagnostik und Therapie.The invention relates to novel ion pairs consisting of ionic metal complexes and halogenated compounds as counterions, methods for producing such ion pairs and their use in diagnostics and therapy.
Kontrastmittel sind unentbehrliche Hilfsmittel in der modernen Diagnostik; viele Erkrankungen sind ohne den Einsatz von Kontrastmitteln nicht diagnostizierbar. Kontrastmittel finden in allen Bereichen der Diagnostik wie z.B. der Röntgen-, Radio- oder Ultraschalldiagnostik oder Magnetresonanztomographie Verwendung.Contrast agents are indispensable aids in modern diagnostics; many diseases cannot be diagnosed without the use of contrast media. Contrast agents can be found in all areas of diagnostics such as X-ray, radio or ultrasound diagnostics or magnetic resonance imaging use.
Kontrastmittel sind in der Regel nur für eine der oben beschriebenen Diagnoseverfahren geeignet, nicht jedoch für mehrere gleichzeitig. Ausnahmen hiervon sind die in WO 93/16375 oder WO 97/1359 beschriebenen Metallkomplexe, die über Amidbindungen an jodsubstituierte Aromaten geknüpft sind. Diese Verbindungen sollen es mit nur einer Applikation des Kontrastmittels erlauben, sowohl NMR- als auch Röntgen-Untersuchungen durchzuführen. Eine Kombination der beiden bildgebenden Verfahren ist in vielen Fällen für eine differenzierte Darstellung und eine zuverlässige Diagnose bestimmter Erkrankungen von Vorteil. Diese Verbindungen sollen insbesondere für die Angiographie geeignet sein. Der
Nachteil dieser Verbindungen liegt jedoch darin, daß die Amidbindungen einerseits nicht übermäßig stabil sind und zum anderen, daß durch eine Amidbindung die Komplexstabilität deutlich herabgesetzt wird und dadurch die Gefahr besteht, daß Metallionen freigesetzt und anschließend in das Knochengewebe eingebaut werden können.Contrast media are generally only suitable for one of the diagnostic methods described above, but not for several at the same time. Exceptions to this are the metal complexes described in WO 93/16375 or WO 97/1359, which are linked to iodine-substituted aromatics via amide bonds. With only one application of the contrast agent, these compounds should allow both NMR and X-ray examinations to be carried out. In many cases, a combination of the two imaging methods is advantageous for a differentiated display and a reliable diagnosis of certain diseases. These compounds are said to be particularly suitable for angiography. The Disadvantages of these compounds, however, are that the amide bonds are not excessively stable on the one hand and on the other hand that complex stability is significantly reduced by an amide bond and there is therefore a risk that metal ions can be released and subsequently incorporated into the bone tissue.
Aufgabe der vorliegenden Erfindung war es daher, neue chemische Verbindungen zur Verfügung zu stellen, die für die Herstellung sehr gut verträglicher und wasserlöslicher Kontrastmittel für die kombinierte Röntgen-, NMR- und/oder Radiodiagnostik geeignet sind.It was therefore an object of the present invention to provide new chemical compounds which are suitable for the production of very well tolerated and water-soluble contrast media for combined X-ray, NMR and / or radio diagnostics.
Diese Aufgabe wird durch die in den Patentansprüchen gekennzeichneten Stoffe, Mittel, Herstellungsverfahren und Verwendungen gelöst.This object is achieved by the substances, agents, production processes and uses characterized in the patent claims.
