Skullcapflavone II, a flavonoid derived from Scutellaria baicalensis, has anti-inflammatory, anti-microbial activities. Skullcapflavone II regulates osteoclast differentiation, survival, and function. Skullcapflavone II exerts potent antimicrobial activity against M. aurum and M. bovis BCG[1][2].
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[2].
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[3].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
