  • Publication number: 20160122764
    Abstract: The present invention relates to a gene specific siRNA related with respiratory diseases, particularly, to a gene specific siRNA related with idiopathic pulmonary fibrosis and chronic obstructive pulmonary disease (COPD), and a highly efficient double-helical oligo RNA structure containing the same, wherein the double-helical oligo RNA structure has a structure in which hydrophilic and hydrophobic materials are bonded at the both ends of the double-helical RNA (siRNA) using a simple covalent bond or a linker-mediated covalent bond to be effectively transferred into a cell, and may be converted into nanoparticles by the hydrophobic interaction of the double-helical oligo RNA structure in a solution. It is desirable that the siRNA contained in the double-helical oligo RNA structure is a siRNA specific to a CTGF, Cyr61, or Plekho1, which are genes related with respiratory diseases, particularly idiopathic pulmonary fibrosis and COPD.

  • Publication number: 20150259690
    Abstract: An amphiregulin-specific double-stranded oligo siRNA structure comprises hydrophilic and hydrophobic compounds bound to the amphiregulin-specific double-stranded oligo siRNA by a simple covalent bond or a linker-mediated covalent bond so as to increase the in vivo stability and intracellular delivery efficiency of the double-stranded oligo siRNA, and to nanoparticles composed of the oligo siRNA structures. The amphiregulin-specific double-stranded oligo siRNA structure can increase the stability of the amphiregulin-specific double-stranded oligo siRNA without impairing the function of the amphiregulin-specific double-stranded oligo siRNA, and at the same time, can efficiently increase the membrane permeability of the double-stranded oligo siRNA.

  • Publication number: 20140371432
    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.
