Selenomethylene Locked Nucleic Acid Enables Reversible Hybridization in Response to Redox Changes

Abstract

Locking up selenium: A new conformationally restricted nucleic acid with a 2′,4′-selenomethylene bridge (SeLNA) can be reversibly converted into its oxidized form (SeOLNA), and the hybridization of a modified oligonucleotide was shown to be dependent on the oxidation state. A SeLNA-modified molecular-beacon-type probe (see scheme; F=fluorophore, Q=quencher) can be used as a sensor for changes in the redox environment.
