Site-specific modification by functionality-transfer oligonucleotide with the photo-inducible reactivity

Abstract

Previously, we reported that S-vinyl thioguanosine analogs exhibited the efficient functionality-transfer reaction with selectivity toward cytidine. This technique was applied to the inhibition and the labelling of DNA or RNA. In this study, we aimed at developing functionality-transfer oligonucleotide with the photo-inducible reactivity. This photo-induced transfer reaction proceeded only to d(m)C but not to dC and dT at the target site of the complementary ODN.
