The present disclosure describes 6-disubstituted bicyclic nucleosides, oligomeric compounds prepared therefrom and methods of using the oligomeric compounds. More particularly, the 6-disubstituted bicyclic nucleosides each comprise a 2′-O—C(Ri)(R2)-4′ or 2′-O—C=(R3)(R.4)-4′ bridge wherein each R is, independently a substituent group and Ri and R2 include H. The 6-disubstituted bicyclic nucleosides are useful for enhancing properties of oligomeric compounds including nuclease resistance. 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.
本公开描述了6-二取代双环核苷酸、从中制备的寡聚化合物以及使用这些寡聚化合物的方法。更具体地说,这些6-二取代双环核苷酸每个包括一个2′-O—C(Ri)(R2)-4′或2′-O—C=(R3)(R4)-4′桥,其中每个R独立地是一个取代基,而Ri和R2包括H。这些6-二取代双环核苷酸对增强包括
核酸酶抗性在内的寡聚化合物的性质是有用的。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。
