|Skullcapflavone II inhibits ovalbumin-induced airway inflammation in a mouse model of asthma.[Pubmed: 22314230]|
|Skullcapflavone II is a flavonoid derived from Scutellaria baicalensis, a widely used herbal medicine in anti-inflammatory and anticancer therapy in Korea. Skullcapflavone II antagonized the bradykinin receptor more potently than any of the other flavonoids derived from this plant.|
METHODS AND RESULTS:
Here, we were investigated its therapeutic effects in a mouse model of ovalbumin (OVA)-induced allergic asthma. Administration of Skullcapflavone II significantly reduced airway hyperresponsiveness (AHR), airway eosinophilia, Th2 cytokine production, and increased transforming growth factor-β1 (TGF-β1) levels in bronchoalveolarlavage (BAL) fluids and lungs from OVA-sensitized and -challenged mice. Skullcapflavone II administration also significantly suppressed subepithelial collagen deposition and goblet cell hyperplasia, elevated Smad7 expression and suppressed pSmad2/3 levels.
Collectively, these findings indicate that Skullcapflavone II, a potential bradykinin antagonist, reduced the major pathophysiological features of allergic asthma, at least in part by acting on TGF-β1/Smad signaling pathways. Thus, Skullcapflavone II may have therapeutic potential for the treatment of allergic asthma.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|Inhibition of cyclooxygenase/lipoxygenase from human platelets by polyhydroxylated/methoxylated flavonoids isolated from medicinal plants.[Pubmed: 10071954]|
|Various flavonoid derivatives were previously reported to possess the inhibitory activity on cyclooxygenase/lipoxygenase. And these properties of flavonoids might contribute to their anti-inflammatory activity in vivo. |
METHODS AND RESULTS:
In this study, several polyhydroxylated/methoxylated flavonoid derivatives such as oroxylin A, wogonin, Skullcapflavone II, tectorigenin and iristectorigenin A were isolated from the medicinal plants. These compounds were evaluated for their inhibitory effects on cyclooxygenase/lipoxygenase from the homogenate of human platelets in vitro. It was found that isoflavones including daidzein and tectorigenin possessed the inhibitory activity on cyclooxygenase, although the potency of inhibition was far less than that of indomethacin. In addition, oroxylin A, baicalein and wogonin inhibited 12-lipoxygenase activity without affecting cyclooxygenase, which suggested that 5,6,7- or 5,7,8-trisubstitutions of A-ring of flavone gave favorable results.
The IC50 values of oroxylin A and NDGA against 12-lipoxygenase were found to be 100 and 1.5 microM, respectively.
