[Interaction of short nucleotide derivatives with nucleic acids. III. photomodification of DNA targets using tandems of short nucleotide derivatives]. / Vzaimodeistvie proizvodnykh korotkikh oligonukleotidov s nukleinovymi kislotami III. Fotomodifikatsiya DNK-mishenei pri ispol'zovanii tandemov proizvodnykh korotkikh oligonukleotidov.

High efficiency was demonstrated for the photomodification of a DNA target by a 5'-p-azidotet-rafluorobenzoyl reagent based on a tetranucleotide and its 3'-phosphoestrone ester in the presence of a pair of flanking effectors. These effectors are oligonucleotide derivatives with N-(2-hydroxyethyl)phenazinium groups or those connected to cholesterol residues at the terminal phosphates.
