Abstract:
플라보카와인 A는 카바 추출물 유래 찰콘 중 주요 구성요소이며, 항암활성 등 다양한 생물학적 활성을 나타낸다. 본 발명자들은 쥐 대식세포에서 LPS로 유도되는 친염증성 매개자 발현 및 이들 활성을 책임지는 분자적 기작에 대한 플라보카와인 A의 억제효과를 시험하였다. 플라보카와인 A는 LPS로 자극시킨 RAW 264.7 세포에서 iNOS와 COX-2의 발현 및 뒤이은 NO와 PGE2의 생산을 현저히 억제하였다. 플라보카와인 A는 LPS로 유도되는 NF-κB와 AP-1 신호전달 경로 활성화를 현저히 저해하였다. 뿐만 아니라, 플라보카와인 A는 LPS로 자극시킨 RAW 264.7 세포에서 iNOS와 COX-2 발현을 담당하는 JNK와 p38 MAPK 활성화를 저해하였다. 또한, 플라보카와인 A는 TNF-α, IL-1β 및 IL-6와 같은 친염증성 사이토카인 생산을 저해하였다. 이러한 결과들은 플라보카와인 A가 쥐 대식세포에서 NF-κB-AP-1-JNK/p38 MAPK 신호전달 경로를 차단함으로써 LPS로 유도되는 친염증성 매개자의 발현을 억제하여 항염증 반응을 나타냄을 제시한다.

Abstract:
PURPOSE: A composition containing Juglans mandshurica-derived PGG(1,2,3,4,6-penta-O-galloyl-beta-D-glucose) is provided to treat and prevent inflammatory dermatitis. CONSTITUTION: A composition for treating skin inflammation and injury caused by inflammation-relating molecule(TNF-alpha, IFN-gamma, and TNF-alpha+IFN-gamma) and TPA contains Juglans mandshurica-derived PGG as an active ingredient. A method for preparing the Juglans mandshurica-derived PGG extract comprises: a step of collecting Juglans mandshurica barks, drying and pulverizing; a step of dipping in acetone-water(7:3,v/v) solution and extracting; a step of filtering the extract using Whatman No. 2 filter paper; a step of concentrating and sequentially fractioning with n-hexane, CH_2Cl_2, and EtOAc; and a step of freeze-drying.
