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].

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
