    • 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.
    • 本发明提供双链RNA结构,其包含与用于治疗疾病,特别是癌症的双螺旋寡聚RNA共价键合的高分子化合物,以增强双螺旋寡聚RNA的递送,以及 还包括与其键合的靶特异性配体,其制备方法,以及使用RNA结构以目标特异性方式递送双螺旋寡聚RNA的技术。 由配体键合的双螺旋寡聚RNA结构组成的纳米粒子可以有效地将双螺旋寡聚RNA递送到靶,因此即使施用双螺旋寡核苷酸RNA也能显示双螺旋寡聚RNA的活性 浓度相对较低。 此外,它可以防止双螺旋寡聚RNA非特异性递送到其他器官和细胞中。 因此,配体键合的双链RNA结构可以用于各种疾病,特别是癌症的治疗,也可以有效地用作新型双螺旋寡聚RNA递送系统。 特别地,配体键合的双链RNA结构可以有效地用于治疗包括癌症和感染性疾病在内的疾病。 此外,本发明涉及一种杂合缀合物,其包含通过共价键与反义寡核苷酸(ASO)的两端键合的亲水性材料和疏水性材料,以增强ASO的体内稳定性,制备方法 杂交缀合物和由缀合物组成的纳米颗粒。 根据本发明的ASO-聚合物缀合物可以增加ASO的体内稳定性,使得可以有效地将治疗性ASO递送到细胞中。 此外,即使以相对低的浓度施用,ASO-聚合物缀合物也可以表现出ASO的活性。
