  Enhanced triple-helix and double-helix formation with oligomers containing modified pyrimidines

  摘要：

  本发明揭示了一种新型寡聚物，与仅含传统碱基的寡聚物相比，其形成双链或三链的能力得到了增强。这些寡聚物含有5-（1-丙炔基）尿嘧啶，5-（1-丙炔基）胞嘧啶或相关类似物。本发明的寡聚物能够（i）通过在生理pH下耦合到靶DNA双链的主沟槽中，与各种靶序列（如病毒或癌基因序列）形成三链，或（ii）通过结合单链DNA或靶基因编码的RNA而形成双链。本发明的寡聚物可以被纳入药学可接受载体中，并可以构建任何所需的序列，只要序列通常包括一种或多种用本发明的类似物替换的碱基。本发明的组合物可以用作治疗各种病毒引起的疾病的药物，也可以用于诊断目的，以检测病毒或疾病情况。

  Novel oligomers are disclosed which have enhanced ability with respect to forming duplexes or triplexes compared with oligomers containing only conventional bases. The oligomers contain the bases 5-(1-propynyl)uracil, 5-(1-propynyl)cytosine or related analogs. The oligomers of the invention are capable of (i) forming triplexes with various target sequences such as virus or oncogene sequences by coupling into the major groove of a target DNA duplex at physiological pH or (ii) forming duplexes by binding to single-stranded DNA or to RNA encoded by target genes. The oligomers of the invention can be constructed to have any desired sequence, provided the sequence normally includes one or more bases that is replaced with the analogs of the invention. Compositions of the invention can be used used for diagnostic purposes in order to detect viruses or disease conditions.
