The invention relates to iRNA agents, which preferably include a monomer in which the ribose moiety has been replaced by a moiety other than ribose.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 lipophilic moiety. e.g., cholesterol, is is directly, or indirectly, tethered. The invention also relates to methods of making and using such modified iRNA agents.
本发明涉及 iRNA 制剂,它最好包括一种单体,其中的
核糖分子已被
核糖以外的分子所取代。 加入这种单体可以调节加入其中的 iRNA 制剂的性质,例如,通过使用非
核糖分子作为
配体或其他实体(如亲脂分子,如
胆固醇)直接或间接的连接点。 本发明还涉及制造和使用这种改性 iRNA 制剂的方法。
