In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Picroside II (6-Vanilloylcatalpol, Vanilloyl catalpol) is the main active ingredient in iridoid glycosides, which is the principal component of Picrorrhiza kurroa Royle. It has antioxidant, anti-inflammatory, immune regulatory, anti-virus and other pharmacological activities.
In vitro Picroside II can reduce H2O2-induced PC12 cell damage and improve cell survival[3]. Picroside II effectively attenuates fatty acid accumulation by decreasing FFAs uptake and lipogenesis. Picroside II also decreases the expression of gluconeogenic genes[4]. Picroside II significantly decreases the concentrations of TNF-α, IL-1β, and IL-6 in cells. It suppresses the activation of p65 NF-κB signaling pathway compared with LPS stimulation[5].
In vivo Picroside II could protect the nervous system possibly through reducing the content of ROS by down-regulating the expression of Rac-1 and Nox2 and could protect the BBB through reducing the expression of ROCK, MLCK, and MMP-2, while enhancing the expression of claudin-5[1]. In the HDM-induced asthmatic model, picroside II significantly reduces inflammatory cell counts in the bronchoalveolar lavage fluid (BALF), the levels of total immunoglobulin (Ig) E and HDM-specific IgE and IgG1 in serum, airway inflammation, and mucus hypersecretion in the lung tissues[2].
