The Cu(II) complexes of cyclen and two of its heterosubstituted analogues were shown to be efficient oxidative DNA cleavers. The reactivity strongly depends on the heteroatom inserted into the macrocycle (O > S > N).
Spezialisierte Enzyme spalten im Körper Nukleinsäuren und Proteine. Doch im Labor gelingt dies auch kleinen Metallkomplexen — beispielsweise Verbindungen mit dem makrocyclischen Liganden Cyclen. Solche DNA‐ und Protein‐Scheren könnten etwa in der Molekularbiologie und für therapeutische Zwecke nützlich sein.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
