  One aspect of the present invention relates to a double-stranded oligonucleotide comprising at least one non-natural nucleobase. In certain embodiments, the non-natural nucleobase is difluorotolyl, nitroindolyl, nitropyrrolyl, or nitroimidazolyl. In a preferred embodiment, the non-natural nucleobase is difluorotolyl. In certain embodiments, only one of the two oligonucleotide strands comprising the double-stranded oligonucleotide contains a non-natural nucleobase. In certain embodiments, both of the oligonucleotide strands comprising the double-stranded oligonucleotide independently contain a non-natural nucleobase. In certain embodiments, the oligonucleotide strands comprise at least one modified sugar moiety. Another aspect of the present invention relates to a single-stranded oligonucleotide comprising at least one non-natural nucleobase. In a preferred embodiment, the non-natural nucleobase is difluorotolyl. In certain embodiments, the ribose sugar moiety that occurs naturally in nucleosides is replaced with a hexose sugar, polycyclic heteroalkyl ring, or cyclohexenyl group. In certain embodiments, at least one phosphate linkage in the oligonucleotide has been replaced with a phosphorothioate linkage.

  本发明的一个方面涉及至少包含一种非天然核碱基的双链寡核苷酸。在某些实施例中，非天然核碱基是二氟基甲苯基、硝基吲哚基、硝基吡咯基或硝基咪唑基。在一个首选实施例中，非天然核碱基是二氟基甲苯基。在某些实施例中，仅有双链寡核苷酸中的两个寡核苷酸链中的一个包含非天然核碱基。在某些实施例中，包含双链寡核苷酸的两个寡核苷酸链独立地包含非天然核碱基。在某些实施例中，寡核苷酸链包括至少一个修饰的糖基团。本发明的另一个方面涉及至少包含一种非天然核碱基的单链寡核苷酸。在一个首选实施例中，非天然核碱基是二氟基甲苯基。在某些实施例中，核苷中天然存在的核苷糖被替换为六碳糖、多环杂基烷基环或环己烯基团。在某些实施例中，寡核苷酸中的至少一个磷酸酯连接被替换为磷酸硫酯连接。
