    公开(公告)日:2006-02-16
    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含有至少一个非自然碱基的双链寡核苷酸。在某些实施例中,非自然碱基可以是二氟基甲苯基、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,非自然碱基是二氟基甲苯基。在某些实施例中,双链寡核苷酸中的两个寡核苷酸链中只有一个含有非自然碱基。在某些实施例中,双链寡核苷酸中的两个寡核苷酸链都独立地含有非自然碱基。在某些实施例中,寡核苷酸链包含至少一个修饰的糖基。本发明的另一个方面涉及含有至少一个非自然碱基的单链寡核苷酸。在一个首选实施例中,非自然碱基是二氟基甲苯基。在某些实施例中,取代了核苷中天然存在的核糖糖基的是己糖糖基、多环杂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键被磷酸硫酯键取代。

  • Efficient synthesis of 2′-O-alkyl ribonucleosides using trichloroacetimidate d-ribofuranosides as ribosyl donors
    作者:Luc Chanteloup、Nguyen t. Thuong
    DOI:10.1016/s0040-4039(00)75987-9
    日期:1994.1
    Trichloroacetimidate-2-O-alkyl-3, 5-O-TIPS-beta-D-ribofuranoside glycosylates silylated nucleobases in a fast high-yielding and stereoselective reaction promoted by trimethylsilyl trifluoromethanesulfonate. This method has been applied to the synthesis of 2'-O-alkyl ribonucleosides further transformed to building blocks ready for oligo(2'-O-alkyl)ribonucleotide construction.
