5' and 2' bis-substituted nucleosides and oligomeric compounds prepared therefrom

摘要

The present invention provides modified nucleosides and oligomeric compounds prepared therefrom. More particularly, the present invention provides modified nucleosides having at least one 5′-substituent and a 2′-O-substituent, oligomeric compounds comprising at least one of these modified nucleosides and methods of using the oligomeric compounds. In some embodiments, the oligomeric compounds provided herein are expected to hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
