摘要：
The present invention relates to a dengue virus-specific siRNA, a high-efficiency double helix oligo-RNA structure comprising the siRNA, and a composition for suppressing the proliferation of dengue virus comprising the RNA structure. The double helix oligo-RNA structure has a structure in which a hydrophilic material and a hydrophobic material are grafted on both ends of a double helix RNA (siRNA) via a simple covalent bond or a linker-mediated covalent bond so that the double helix oligo-RNA structure is efficiently delivered into cells, and can be transformed into a nanoparticle type by a hydrophobic interaction of the double helix RNA structures in an aqueous solution. The siRNA included in the double helix oligo-RNA structure specifically acts on the serotype of all dengue viruses. In addition, the present invention relates to a method for preparing the double helix oligo-RNA structure, and a pharmaceutical composition containing the double helix oligo-RNA structure for preventing or treating a dengue virus infection.
