Cu²⁺-Adeninring-Wechselwirkung in den Cu²⁺-Komplexen von Adenosin-5′- und Adenosin-3′-monophosphat

Summary

By means of UV and NMR spectroscopy evidence is given for direct interaction between metal ion and heteroaromatic groups in both Cu²⁺-adenosine-5′-monophosphate and Cu²⁺-adenosine-3′-monophosphate complexes. A comparison with the Cu²⁺-adenosine system shows that this interaction is much enhanced in the monophosphate analogues, which points to the existence of a macrocyclic phosphate-metal-adenine chelate.
