Provided herein are novel 5'-(S)-CH3 substituted bicyclic nucleosides, oligomeric compounds prepared therefrom and methods of using the oligomeric compounds. More particularly, the furanose ring of each of the novel 5'-(S)-CH3 substituted bicyclic nucleosides includes a 2' to 4' bridging group. The 5'-(S)-CH3 substituted bicyclic nucleosides are expected to be useful for enhancing one or more properties of the oligomeric compounds they are incorporated into such as for example increasing the binding affinity. In certain embodiments, the oligomeric compounds provided herein hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
本文提供了新颖的5'-(S)-
CH3取代的双环核苷,以及由其制备的寡聚化合物和使用这些寡聚化合物的方法。更具体地,每个新颖的5'-(S)- 取代的双环核苷的
呋喃糖环包括一个2'到4'的桥联基团。预计这些5'-(S)- 取代的双环核苷将有助于增强它们所并入的寡聚化合物的一个或多个性质,例如增加结合亲和力。在某些实施例中,本文提供的寡聚化合物与靶RNA的部分杂交,导致靶RNA的正常功能丧失。
