    摘要: Provided herein are bicyeMc nucleosides comprising a substituted amino group in the bridge, oligomeric compounds having at least one of these bicyclic nucleosides and methods of using the oligomeric compounds. The bicyclic nucleosides comprising a substituted amino group in the bridge are useful for enhancing properties of oligomeric compounds including nuclease resistance, in certain embodiments, the oligomeric compounds hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.

    摘要: The present invention provides double stranded compositions wherein each strand is modified to have a motif defined by positioning of β-D-ribonucleosides and sugar modified nucleosides. More particularly, the present compositions comprise one strand having an alternating motif and another strand having a hemimer motif, a blockmer motif, a fully modified motif or a positionally modified motif. At least one of the strands has complementarity to a nucleic acid target. The compositions are useful for targeting selected nucleic acid molecules and modulating the expression of one or more genes. In preferred embodiments the compositions of the present invention hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA. The present invention also provides methods for modulating gene expression.
