Apple mint (Mentha suaveolens) has been widely used in traditional herbal medicine since it shows hypotensive, analgesic, and anti-inflammatory effects. The active ingredient of apple mint is rosmarinic acid (RA), an ester of caffeic acid and 3,4-dihydroxyphenyl lactic acid. RA has many pharmacological effects, such as anti-oxidative, anti-apoptotic, anti-tumorigenic, and anti-inflammatory properties. In this study, RA is incorporated in PEGylated liposomes to enhance its pharmacological effects. The physical characteristics of RA liposomes were demonstrated by dynamic light scattering, zeta potential, and field emission scanning electron microscopy. The anti-oxidation and anti-cancer effects of RA liposomes were evaluated in HT22 and MDA-MB-231 cell lines, respectively.
애플 민트(Mentha suaveolens)는 전통적으로 사용된 허브의 한 종류로써 저혈압, 진통, 항염 효과를 갖고 있다. 로즈마린 산(rosmarinic acid, RA)은 그 활성 성분으로 알려져 있다. RA는 항산화, 항세포사멸, 항암, 항염증과 같은 약리학적 효과를 나타내는 것으로 알려져 있다. 본 연구에서는 RA를 폴리에틸렌 글리콜과 리피드를 이용하여 리포좀화시켜 기존의 RA 보다 더 높은 약리학적 효과를 나타내는 약물전달체를 개발하였다. 광적동산란(dynamic light scattering), 제트 전위(zeta potential), 전계 방사형 주사전자현미경(field emission scanning electron microscopy) 등을 이용한 입자의 물리화학적 물성을 분석하고, 마우스 해마 유래 세포주인 HT22에서 항산화 효과 및 사람 유방암 유래 세포주인 MDA-MB-231에서 확인하였다.
