Zusammenfassung:The present invention relates to a composition for administering a double-stranded oligonucleotide structure using an ultrasonic nebulizer. The method allows the double-stranded oligonucleotide, according to the present invention, which forms self-assembled nanoparticles having a neutral charge of 90 nm in an aqueous solution, to maintain the same concentration, molecular weight, purity, nanoparticle size, and osmolality as the undiluted solution material. In addition, the method can maintain target gene suppression ability without cytotoxicity and can deliver drugs specifically to the nasal cavity and lungs, thus allowing the present invention to be utilized in the prevention or treatment of respiratory viral infections including COVID-19, pulmonary fibrosis caused by viral infections, or respiratory diseases. La présente invention concerne une composition pour l'administration d'une structure oligonucléotidique bicaténaire à l'aide d'un nébuliseur à ultrasons. Le procédé permet à l'oligonucléotide bicaténaire selon la présente invention, qui forme des nanoparticules auto-assemblées ayant une charge neutre de 90 nm dans une solution aqueuse, d'être maintenu à la même concentration, au même poids moléculaire, à la même pureté, à la même taille des nanoparticules et à la même osmolalité que la matière de solution non diluée. De plus, le procédé peut maintenir une capacité de suppression de gène cible sans cytotoxicité et peut administrer des médicaments spécifiquement à la cavité nasale et aux poumons, ce qui permet d'utiliser la présente invention dans la prévention ou le traitement d'infections virales respiratoires y compris la COVID-19, de la fibrose pulmonaire provoquée par des infections virales, ou de maladies respiratoires. 본 발명은 초음파 방식 연무식 흡입기 (nebulizer)를 이용한 이중가닥 올리고뉴클레오티드 구조체 투여용 조성물에 관한 것으로, 상기 방법은 수용액상에서 90 nm 크기의 중성전하를 가지는 자가조립 나노입자를 형성하는 본 발명에 따른 이중가닥 올리고뉴클레오티드를 원액 물질과 동일한 농도, 분자량, 순도, 나노입자 크기, 삼투압몰농도를 유지할 수 있을 뿐만 아니라, 세포독성 없이 타겟 유전자 억제능을 유지하며 비강 및 및 폐 특이적으로 전달할 수 있는바, COVID-19를 포함하는 호흡기 바이러스 감염증, 바이러스 감염에 의한 폐섬유증, 또는 호흡기 질환 예방 또는 치료에 유용하게 활용 가능하다.
