In a previous study, we isolated 11 different kinds of compounds from ethyl acetate fractions of lees (jubak) which is a by-product of Korean traditional wine production. These compounds were identified as caffeic acid, coumaric acid, D-mannitol, ferulic acid, hesperetin, hesperidin, naringenin, nar...

염증이란 무엇인가? | 염증이란 다양한 외부자극으로 인해 발생되는 신체 방어기작의 하나로서, lipopolysaccharide (LPS)와 같은 세균 유래 내독소(endotoxin)는 대표적인 염증 유도 물질로 알려져 있다[2]. LPS는 그람 음성세균의 세포벽 구성성분으로서, 대식세포에 의한 염증반응을 유도하는 성분으로 알려져 있으며, 대표적인 pattern recognition receptor인 toll-like receptor 4(TLR4)와 MD-2의 복합체에 의해 인식된다. | |
Hesperetin이란 어떤 형태로 존재하는 물질인가? | Hesperetin은 감귤 등의 Citrus 속 식물의 과피에 hesperetin 7-rutinoside 인 hesperidin 배당체 형태로 1.5~3. | |
Hesperetin의 보고된 생리활성은 무엇이 있는가? | 천연물을 이용한 생리활성 연구가 진행됨에 따라 이들 flavonoid에 의한 항암[24], 항산화[17], 그리고 항균 활성[9, 18]등 다양한 생리활성이 보고된 바 있다. 특히, hesperidin은 항암[1], 항산화[11, 13] 그리고 항염증[20]등에서 강한 활성을 나타내는 대표적인 flavonoid 물질로 연구되고 있으며 또한 전구체인 chalcone 계 물질 역시 mitogen-activated protein kinases (MAPKs) 및 NF-κB (nuclear factor-kappaB) 경로를 억제하고[6], 염증 매개인자인 inducible nitric oxide synthase (iNOS)의 발현과 nitric oxide (NO)의 합성을 억제한다는 것이 보고된 바 있다[4]. 반면, 핵심 구조체인 hesperetin에 의한 lipopolysaccharide(LPS) 염증 모델에서의 항염증 활성 연구는 미미한 수준이다. |
