Abstract

Official abstract text for this publication.

The present invention provides nucleosides of formula (1) and oligonucleotides comprising at least one nucleoside of formula (2): Another aspect of the invention relates to a method of inhibiting the expression of a gene in cell, 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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A nucleoside of formula (1): wherein: one of D 1 and D 2 is H, or a hydroxyl protecting group, and the other of D 1 and D 2 is H, a hydroxyl protecting group, or a reactive phosphorus group, provided that when one of D 1 and D 2 is a reactive phosphorus group, the other of D 1 and D 2 is a hydroxyl protecting group; m is an integer…
