Publication number: 20140371432Abstract: The present invention provides a double-stranded RNA structure, which comprises a polymer compound covalently bonded to a double-helix oligo RNA useful for the treatment of diseases, particularly cancer, in order to enhance the delivery of the double-helix oligo RNA, and further comprises a target-specific ligand bonded thereto, a preparation method thereof, and a technique of delivering the double-helix oligo RNA in a target-specific manner using the RNA structure. A nanoparticle composed of the ligand-bonded double-helix oligo RNA structures can efficiently deliver the double-helix oligo RNA to a target, and thus can exhibit the activity of the double-helix oligo RNA even when the double-helix oligo RNA is administered at a relatively low concentration. Also, it can prevent the non-specific delivery of the double-helix oligo RNA into other organs and cells.Type: ApplicationFiled: December 14, 2012Publication date: December 18, 2014Inventors: Jeiwook Chae, Boram Han, Han-na Kim, Han Oh Park, Pyoung Oh Yoon, Sun Gi Kim, Kwang-Ju Jung, Taewoo Kwon, Jong Deok Choi, Sam Young Lee, Eun-Jung Jung
