Bicyclol (SY801) is an orally active derivative of the traditional Chinese medicine Schisandra chinensis, which has antiviral, anti-inflammatory, immunomodulatory, antioxidant, anti-steatosis, anti-fibrotic and anti-tumor activities. Bicyclol regulates the expression of heat shock proteins and plays an anti-apoptosis role in hepatocytes. Bicyclol reduces the activation of NF-κB and the levels of inflammatory factors in hepatocytes infected with hepatitis C virus (HCV) by inhibiting the activation of the ROS-MAPK-NF-κB pathway, and prevents ferroptosis in acute liver injury. Bicyclol can change the expression of Mdr-1, GSH/GST and Bcl-2, increase the intracellular concentration of anticancer drugs, and sensitize drug-resistant cells to anticancer drugs. Bicyclol inhibits the proliferation of human malignant hepatoma cells by regulating the PI3K/AKT pathway and the Ras/Raf/MEK/ERK pathway. Bicyclol can be used in the study of chronic hepatitis, acute liver injury, nonalcoholic fatty liver disease, liver fibrosis and hepatocellular carcinoma.

Bicyclol (300 mg/kg; p.o.; once daily for 3 days) alleviates ConA- and Acetaminophen (HY-66005) induced liver damage in mice, reducing serum transaminases, liver necrosis, mitochondrial cytochrome C and apoptosis-inducing factor (AIF) release, and liver DNA fragmentation[1].
Bicyclol (75 and 150 mg/kg; p.o.; 6 times per week except Sunday for 7 weeks) significantly improves liver damage and fibrosis in rats and mice induces by chronic CCl4 and Dimethylnitosamine hepatotoxicity1].
Bicyclol (25 and 50 mg/kg; p.o.; once every other day for 4 weeks) alleviates hyperlipidemia and liver damage and inhibites inflammatory signaling pathways in HFD-induced NAFLD mice[2].
Bicyclol (200 mg/kg; i.p.; 3 times a day for 2 days) inhibits iron-induced apoptosis in the liver of CCl4-induced ALI mice and exerts a hepatoprotective effect[5].

*Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles. Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
