Radiolytic one-electron reductive cyclization of oligodeoxynucleotides possessing a disulfide bond.
Radiolytic one-electron reduction of oligodeoxynucleotides (ODNs) possessing a disulfide bond induced strand exchange reaction in a hypoxia selective manner. In this study, we attempted to apply this radiolytic reaction to stem-and-loop structured ODNs. Hypoxic X-irradiation to an aqueous solution of stem-and-loop structured ODNs produced a cyclized DNA in good yield via an intrastrand ligation reaction.
