    摘要: The present invention provides nucleosides and oligonucleotides comprising a 5′ phosphate mimics of formula (IVc) or (Vc). One aspect of the present invention relates to modified nucleosides and oligonucleotides comprising such dinucleotide of formula (Ia). Another aspect of the invention relates to a method of inhibiting the expression of a gene in call, the method comprising (a) contacting an oligonucleotide of the invention with the cell; and (b) maintaining the cell from step (a) for a time sufficient to obtain degradation of the mRNA of the target gene.

    摘要: The invention relates to iRNA agents, which preferably include a monomer in which the ribose moiety has been replaced by a moiety other than ribose. The inclusion of such a monomer can allow for modulation of a property of the iRNA agent into which it is incorporated, e.g., by using the non-ribose moiety as a point to which a ligand or other entity, e.g., a carbohydrate; or a steroid, e.g., cholesterol, which is optionally substituted with at least one carbohydrate. is directly, or indirectly, tethered. The invention also relates to methods of making and using such modified iRNA agents.
