  • Publication number: 20190119672
    Abstract: The present invention relates to a multi siRNA complex with increased intracellular transmission capacity and a multi-functional nucleic acid structure complex. The siRNA complex and multi-functional nucleic acid structure complex according to the invention have the advantage of having a novel structure that enables easier chemical synthesis compared to the existing shRNA system used to inhibit expression of a plurality of target genes and also enabling the inhibition of the expression of a plurality of genes at enhanced efficiencies compared to the existing siRNA. In addition, because it has high intracellular transmission capacity and also enables inhibition of the expression of target genes specifically without incurring non-specific antiviral reactions, it is very useful as the therapeutic agent mediated by the siRNA mechanism to treat cancer or viral infection.
