Abstract

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. Accordingly, the ligand-bonded double-stranded RNA structure can be used for the treatment for various diseases, particularly cancer, and can also be effectively used as a new type of double-helix oligo RNA delivery system. Particularly, the ligand-bonded double-stranded RNA structure can be effectively used for the treatment of diseases, including cancer and infectious diseases. Moreover, the present invention relates to a hybrid conjugate, which comprises a hydrophilic material and hydrophobic material bonded to both ends of an antisense oligonucleotide (ASO) by a covalent bond in order to enhance the in vivo stability of the ASO, a method for preparing the hybrid conjugate, and a nanoparticle composed of the conjugates. The ASO-polymer conjugate according to the invention can increase the in vivo stability of the ASO, making it possible to efficiently deliver the therapeutic ASO into cells. Also, the ASO-polymer conjugate can exhibit the activity of the ASO even when it is administered at a relatively low concentration.

Abstract

Disclosed are hybrid conjugates formed by covalently bonding siRNA (small interfering RNA) molecules to hydrophilic polymers for improving stability of the siRNA molecules effective for gene therapy in vivo, and polyelectrolyte complex micelles formed by ionic interactions between the conjugates and multifunctional cationic compounds. The siRNA-hydrophilic polymer conjugates and polyelectrolyte complex micelles derived therefrom can be advantageously used for improving stability of the siRNA molecules in vivo. Consequently, the delivery of siRNA molecules for therapeutic applications into cells can be facilitated, and the siRNA is still active even though a small dose of the siRNA is used.
