  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    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.

  提供了以下通式表达的核苷酸类似物：其中B代表具有2位羰基氧或2-羟基苯基基团的芳香碱基，或者含有一个或多个核苷酸类似物的寡核苷酸衍生物。这些寡核苷酸衍生物是三链体形成寡核苷酸衍生物，能够在抗原法中与目标双链DNA特异性结合，形成三链体，并能有效地控制和抑制相关基因的表达，同时表现出对核酸酶的高抗性。
