terebrata 로부터 분리한 라말린의 신규한 용도인 항염증 활성에 관한 것으로, 더욱 자세하게는 라말린을 유효성분으로 함유하는 약학조성물에 관한 것이다. 본 발명의 라말린은 천연물 유래의 물질로 독성 및 부작용이 없으며, iNOS(산화질소생성효소)의 발현을 전사단계에서 억제하여 염증 반응의 핵심 매개물질인 NO(산화질소)의 생성을 현저히 억제하고, 염증매개전구물질인 NF-κB의 활성화를 억제하고, p38 MAPK, ERK1/2 및 JNK 신호전달 경로를 억제하고, LPS 수용체인 TLR4의 발현도 억제한 결과 나타나는 탁월한 항염증 효과를 가지므로, 이를 함유하는 조성물은 염증질환 또는 면역질환들을 근본적으로 치료하고 예방할 뿐만 아니라 증상을 완화 및 개선시키는데 유용하게 사용될 수 있다.
Abstract:
PURPOSE: A composition containing ohioensin F which is derived from Polytrichastrum alpinum for preventing or treating atherosclerosis is provided to suppress the expression of a cell adhesion molecule induced by TNF-alpha. CONSTITUTION: A pharmaceutical composition for preventing or treating artherosclerosis contains 0.01-10 wt% of ohioensin F denoted by chemical formula I, which is a benzonaphthoxanthenone-based compound, as an active ingredient. Ohioensin F suppresses the expression of a cell adhesion molecule induced by TNF-alpha. The cell adhesion molecule is ICAM-1 and VCAM-1.
