  One aspect of the present invention relates to a ribonucleoside substituted with a phosphonamidite group at the 3′-position. In certain embodiments, the phosphonamidite is an alkyl phosphonamidite. Another aspect of the present invention relates to a double-stranded oligonucleotide comprising at least one non-phosphate linkage. Representative non-phosphate linkages include phosphonate, hydroxylamine, hydroxylhydrazinyl, amide, and carbamate linkages. In certain embodiments, the non-phosphate linkage is a phosphonate linkage. In certain embodiments, a non-phosphate linkage occurs in only one strand. In certain embodiments, a non-phosphate linkage occurs in both strands. In certain embodiments, a ligand is bound to one of the oligonucleotide strands comprising the double-stranded oligonucleotide. In certain embodiments, a ligand is bound to both of the oligonucleotide strands comprising the double-stranded oligonucleotide. 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-phosphate linkage. Representative non-phosphate linkages include phosphonate, hydroxylamine, hydroxylhydrazinyl, amide, and carbamate linkages. In certain embodiments, the non-phosphate linkage is a phosphonate linkage. In certain embodiments, a ligand is bound to the oligonucleotide strand. In certain embodiments, the oligonucleotide comprises at least one modified sugar moiety.

  本发明的一个方面涉及在3'-位置用磷酰胺基团取代的核糖核苷。在某些实施例中，磷酰胺基团是烷基磷酰胺基团。本发明的另一个方面涉及包含至少一个非磷酸酯连接的双链寡核苷酸。代表性的非磷酸酯连接包括磷酸酯、羟胺、羟基肼基、酰胺和碳酸酯连接。在某些实施例中，非磷酸酯连接是磷酸酯连接。在某些实施例中，非磷酸酯连接仅出现在一条链中。在某些实施例中，非磷酸酯连接出现在两条链中。在某些实施例中，配体结合到包含双链寡核苷酸的寡核苷酸链中的一条链上。在某些实施例中，配体结合到包含双链寡核苷酸的寡核苷酸链中的两条链上。在某些实施例中，寡核苷酸链包含至少一个修饰的糖基团。本发明的另一个方面涉及包含至少一个非磷酸酯连接的单链寡核苷酸。代表性的非磷酸酯连接包括磷酸酯、羟胺、羟基肼基、酰胺和碳酸酯连接。在某些实施例中，非磷酸酯连接是磷酸酯连接。在某些实施例中，配体结合到寡核苷酸链上。在某些实施例中，寡核苷酸包含至少一个修饰的糖基团。

  One aspect of the present invention relates to a double-stranded oligonucleotide comprising at least one ligand. In certain embodiments, a ligand is bound to only one of the two oligonucleotide strands comprising the double-stranded oligonucleotide. In certain embodiments, both of the oligonucleotide strands of the double-stranded oligonucleotide independently comprise a bound ligand. In certain embodiments, the oligonucleotide strands comprise at least one modified sugar moiety. In certain embodiments, a phosphate linkage in one or both of the strands of the oligonucleotide has been replaced with a phosphorothioate or phosphorodithioate linkage. In a preferred embodiment, the ligand is cholesterol or 5β-cholanic acid. Another aspect of the present invention relates to a single-stranded oligonucleotide comprising at least one ligand. In certain embodiments, the oligonucleotide comprises at least one modified sugar moiety. In certain embodiments, a phosphate linkage of the oligonucleotide has been replaced with a phosphorothioate or phosphorodithioate linkage. In a preferred embodiment, the ligand is cholesterol or 5β-cholanic acid. The ligand improves the pharmacokinetic properties of the oligonucleotide.

  本发明的一个方面涉及包含至少一个配体的双链寡核苷酸。在某些实施例中，配体仅结合到构成双链寡核苷酸的两个核苷酸链中的一个。在某些实施例中，双链寡核苷酸的两个核苷酸链都独立地包含一个结合的配体。在某些实施例中，核苷酸链包含至少一个修饰的糖基。在某些实施例中，核苷酸链的一个或两个链中的磷酸酯键已被磷硫酸酯或磷二硫酸酯键替代。在一个首选实施例中，配体是胆固醇或5β-胆烷酸。本发明的另一个方面涉及包含至少一个配体的单链寡核苷酸。在某些实施例中，核苷酸包含至少一个修饰的糖基。在某些实施例中，核苷酸的磷酸酯键已被磷硫酸酯或磷二硫酸酯键替代。在一个首选实施例中，配体是胆固醇或5β-胆烷酸。配体改善了寡核苷酸的药代动力学性能。
