  Base-pair recognition ability of hydroxyphenyl nucleobases in parallel triplex DNA

  摘要：

  Oligonucleotides containing 2'-deoxyribonucleotides bearing hydroxyphenyl nucleobases or their 2',4'-BNA-modified analogs were synthesized, and the triplex-forming ability of their oligonucleotides with double-stranded DNA targets was evaluated by UV melting experiments. Results showed that 2'-deoxyribonucleotide bearing 2'-hydroxyphenyl nucleobase could be recognized by a dUA base pair while no affinity to a TA base pair was observed. The,4'-BNA modification led to a further increase in the binding affinity to a dUA base pair. The,4'-BNA bearing 3-hydroxyphenyl nucleobase showed moderate binding affinity to a TA base pair, but without selectivity. (C) 2013 Elsevier Ltd. All rights reserved.

  Nucleoside analogues expressed by the following general formula 1 where B represents an aromatic base having carbonyl oxygen at the 2-position, or a 2-hydroxyphenyl group, or oligonucleotide derivatives containing one or more of the nucleoside analogues are provided. The oligonucleotide derivatives are triplex-forming oligonucleotide derivatives which bind specifically to target double-stranded DNA with high affinity in the antigene method to form triplexes, and can thereby control and inhibit the expression of relevant genes efficiently, and which show high resistance to nucleases.
