Schisandrins (schizandrins) are a group of bioactive chemical compounds found in Schisandra chinensis, one member of which is Schisandrin C. Schizandrin C exerts anti-neuroinflammatory effects by upregulating phase II detoxifying/antioxidant enzymes via cAMP/PKA/CREB and Nrf-2 signaling. Also was shown, that among human hepatocellular carcinoma cells (Bel-7402), human breast cancer cells (Bcap37) and human nasopharyngeal carcinoma cells (KB-3-1), Bel-7402 cells were most sensitive with IC50 equal to 81.58 ± 1.06 μ M after treatment with schisandrin C. Although the mechanism of tumor inhibiting activity of schisandrin C is not clarified, there are some reports about dibenzocyclooctadiene lignans inducing cancer cell apoptosis. Further investigations are needed to determine in more detail the molecular mechanism, such as the dependent pathway of this apoptotic process, the signal transduction pathways involved and the possible changes in expression of other apoptosis-related genes. Recently was also speculated, that Schisandrin C offered protection against Aβ1-42 -induced dysfunction in learning and memory by inhibiting total cholinesterase and its antioxidant action.

Among human hepatocelluar carcinoma cells (Bel-7402), human breast cancer cells (Bcap37) and human nasopharyngeal carcinoma cells (KB-3-1), Bel-7402 cells were most sensitive with IC50 equal to 81.58 ± 1.06 μ M after treatment with schisandrin C for 48 h. Cytotoxicity of schisandrin C on tumor cells depends on cellular accumulation of the drug. Cells were placed within 96-well culture plates (104 cells/well) respectively, and allowed to attach for 24 h before treatment. The cells were treated with schisandrin C ranging from 12.5 to 200 μ m or without (vehicle control, 0.5% DMSO) schisandrin C for cell lines. Schisandrin C cytotoxicity was measured after 48 h of culture using the MTT assay.
