Biological Activity

Description Schisandrin B is the most abundant dibenzocyclooctadiene lignan present in the traditional Chinese medicinal herb Schisandra chinensis (Turcz.) Baill. It is a kind of ATR and P-gp inhibitor with high safety.
Targets
P-gp [10]
(Cell-based assay)		 ATR [2]
7.25 μM
In vitro
In vitro Schisandrin B is able to induce high level of apoptosis in human hepatic carcinoma cells and human leukemia cells. [1] Schisandrin B decreases the viability of adenocarcinoma cells after UV exposure. The specific inhibitory effect of schisandrin B on ATR protein kinase activity (a DNA repair enzyme) following DNA damage in cells may be useful in anti-cancer therapy. [2] Schisandrin B is found to be the only molecule being a cardioprotective agent as well as a dual inhibitor of P-glycoprotein and multidrug resistance-associated protein 1, which is potentially applicable to treat cancers, especially those displaying multidrug resistance. [3] [4]
In Vivo
In vivo Schisandrin B can protect liver against toxicant challenge. Schisandrin B pretreatment protects against carbon tetrachloride- or TNFα-induced liver damage in mice. [5] [6] [7] Further studies demonstrate the protective effect of schisandrin B on free radical-induced damage in various vital organs, including the heart, liver, kidney, brain and skin. [8] Moreover, schisandrin B is found to attenuate cancer invasion and metastasis via inhibiting epithelial mesenchymal transition at the step of local invasion. [9]

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.
