摘要:
The present invention relates to a method of preparing gelatin nanoparticles manufactures gelatin nanoparticles by constructing an O/W/O or W/O system without a homogenizer, wherein the gelatin nanoparticles are free from the immune system, have a prolonged circulation time in a human body in comparison with that of hydrophobic particles, have enhanced permeability and retention (EPR) effect against cancer cells, have a size of about 200 nm, and may or may not be loaded with a poorly water soluble drug. The poorly water soluble drug of the present invention comprises paclitaxel, which is a poorly soluble anticancer drug, and Coenzyme Q10, ursodeoxycholic acid, ilaprazole, and imatinib mesylate. Further, the O/W/O and W/O systems each represent a nonpolar/polar/non-volatile nonpolar system and a polar/non-volatile nonpolar system respectively, and more specifically, the O/W/O and W/O systems each represent a poorly soluble drug/gelatin nanoparticle/fatty acid system and a gelatin nanoparticle/fatty acid system structure.본 발명은 면역체계로부터 자유로와 인체 내부에서의 순환시간이 혐수성 입자보다 상대적으로 연장되고 암세포에 대한 EPR(Enhanced permeability and retention) 효과가 제고되는; 물에 대한 난용성 약물이 담지되거나 담지되지 않은 200 nm 크기 정도의 젤라틴 나노입자를; 각각 O/W/O 또는 W/O시스템을 구축하여 균질기(homogenizer) 없이 제조하는 방법에관한것으로, 본 발명 난용성 약물은 난용성 항암제인 파클리탁셀, 코엔자임큐텐, 우루소데옥시콜린산, 일라프라졸, 및 이마티닙 메실레이트를 포함하고 상기 O/W/O 및 W/O시스템은 각각 비극(nonpolar)상/극(polar)상/비휘발성 비극(nonpolar)상 및 극(polar)상/비휘발성 비극(nonpolar)상 시스템으로 더욱 상세하게는 O/W/O 및 W/O시스템의 경우 각각 난용성 약물/젤라틴 나노입자/fatty acid 및 젤라틴 나노입자/fatty acid 시스템 구조를 제시한다.
