여러 가지 효소에 의해 naringenin으로부터 합성된다. 그러나, 포플러에서는 플라보노이드 합성에 관여하는 효소들의 연구가 거의 이루어지지 않았다. 포플러에서 flavone synthase I 유전자를 RT-PCR방법을 이용하여 클로닝하였다. PFNS I-1 유전자의 기질 특성을 알아보기 위하여 대장균에 과발현하여 glutathione S-transferase 친화 크로마토그래피를 이용하여 정제하였다. 정제한 PFNS I-1 재조합 단백질은 flavanone인 2S-naringenin기질을 이용하여 flavone인 apigenin을 생성함을 알 수 있었다. 또한 cofactor인 oxoglutarate,... -

synthase (iNOS) and tumor necrosis factor (TNF)-α in lipopolysaccharide (LPS)-activated RAW264.7 cells. In addition, SCT also dampened nuclear factor (NF)-κB-driven expression of a luciferase reporter gene upon transfection of a TIR-domain-containing adapter-inducing interferon-β (TRIF) construct into Human embryonic kidney 293 (HEK 293) cells; similarly, NF-κB nuclear translocation was inhibited by SCT. Moreover, the phosphorylation levels of various upstream signaling enzymes involved in... -

It has been shown that the extracts including eupatilin and quercetin-3-β-D-glucuronopyranoside had mucoprotective effects on the esophagus and stomach through their antioxidant activities. This study was designed to investigate the anti-inflammatory effect of these flavonoid compounds in an animal model of inflammatory bowel disease induced by 2,4,6-trinitrobenzene sulfonic acid. Experimental colitis was induced by intracolonic administration of 2,4,6-trinitrobenzene sulfonic acid. Extracts... -

Gastrointestinal motility consists of phasic slow-wave contractions and the migrating motor complex (MMC). Eupatilin (StillenⓇ) has been widely used to treat gastritis and peptic ulcers, and various cytokines and neuropeptides are thought to be involved, which can affect gastrointestinal motility. We performed a study to identify the effects of eupatilin on lower gastrointestinal motility with electromechanical recordings of smooth muscles in the human ileum and colon. Ileum and colon... -
