黃芩
黃芩為唇形科多年生草本。其有效成分為黃芩素、黃芩甙、漢黃芩素、黃芩新素等5種黃酮成分。此外，還含有β-谷甾醇、苯甲酸、黃芩酶等。有抑菌、抗病毒、鎮(zhèn)靜、利尿、保肝、保膽、解毒、消炎及使血糖上升等作用。主要用于治療爛鰓病、癤瘡病、打印病、出血性敗血癥、腸炎病等。生物活性
Skullcapflavone II 是從黃芩中提取的黃酮類化合物，具有抗炎、抗菌作用。Skullcapflavone II 調(diào)節(jié)破骨細(xì)胞的分化、存活和功能。Skullcapflavone II 對(duì) M. aurum 和M. bovis BCG 具有較強(qiáng)的抗菌活性。體外研究
Skullcapflavone II inhibits osteoclastogenesis with decreased activation of MAPKs, Src, and cAMP response element-binding protein (CREB), which have been known to be redox sensitive. Skullcapflavone II decreases reactive oxygen species by scavenging them or activating nuclear factor-erythroid 2-related factor 2 (Nrf2), and its effects were partially reversed by hydrogen peroxide cotreatment or Nrf2 deficiency.
體內(nèi)研究
Skullcapflavone II, a potential bradykinin antagonist, reduces the major pathophysiological features of allergic asthma, at least in part by acting on TGF-β1/Smad signaling pathways.
