抜粋

Expansion of the triplex DNA forming sequence is required in the genomic targeting fields. Basically, triplex DNA is formed by the interaction between the triplex-forming oligonucleotides and homo-purine region with the target duplex DNA. The presence of the base pair conversion sites hampers stable triplex formation. To overcome this limitation, it is necessary to develop an artificial nucleic acid to recognize the base conversion sites, and the CG and TA base pairs. We describe the synthesis of C-nucleoside analogues and an evaluation of the ability of triplex formation. Consequently, the combined use of the novel C-nucleoside analogues, AY-AY-d(Y-NH2), AY-d(Y-Cl) and IAP-d(Y-Cl), is capable of recognizing duplex DNA including the TA or dUA base pair.
