|Schisandrin C exerts anti-neuroinflammatory effects by upregulating phase II detoxifying/antioxidant enzymes in microglia.[Pubmed: 23859871]|
|We investigated the anti-neuroinflammatory properties of Schizandrin C by focusing on its roles in the induction of phase II detoxifying/antioxidant enzymes and in the modulation of upstream signaling pathways.
METHODS AND RESULTS:
Schizandrin C induced expression of phase II detoxifying/antioxidant enzymes including heme oxygenase-1 (HO-1) and NADPH dehydrogenase quinone-1 (NQO-1). Activation of upstream signaling pathways, such as the cAMP/protein kinase A/cAMP response element-binding protein (cAMP/PKA/CREB) and erythroid-specific nuclear factor-regulated factor 2 (Nrf-2) pathways, significantly increased following treatment with Schizandrin C. In addition, expressions of Schizandrin C-mediated phase II detoxifying/antioxidant enzymes were completely attenuated by adenylyl cyclase inhibitor (ddAdo) and protein kinase A (PKA) inhibitor (H-89). In microglia, Schizandrin C significantly inhibited lipoteichoic acid (LTA)-stimulated pro-inflammatory cytokines and chemokines, prostaglandin E2 (PGE2), nitric oxide (NO), and reactive oxygen species (ROS) production, and inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and matrix metallopeptidase-9 (MMP-9) protein expressions. Moreover, Schizandrin C suppressed LTA-induced nuclear factor-kappa B (NF-κB), activator protein-1 (AP-1), janus-kinase/signal transducer and activator of transcription (JAK-STATs), and mitogen-activated protein kinase (MAPK) activation. Schizandrin C also effectively suppressed ROS generation and NO production, as well as iNOS promoter activity in LTA-stimulated microglia. This suppressive effect was reversed by transfection with Nrf-2 and HO-1 siRNA and co-treatment with inhibitors ddAdo and H-89.
Our results indicate that Schizandrin C isolated from Schisandra chinensis could be used as a natural anti-neuroinflammatory agent, inducing phase II detoxifying/antioxidant enzymes via cAMP/PKA/CREB and Nrf-2 signaling.
Schizandrin C Description
||The seeds of Schisandra chinensis (Turcz.) Baill.
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Protection of seven dibenzocyclooctadiene lignans from Schisandra chinensis against serum and glucose deprivation injury in SH-SY5Y cells.[Pubmed: 26289388 ]|
|Dibenzocyclooctadiene lignans, the major active components of fruit of Schisandra chinensis (Turcz.) Baill., have been found to have activities that could prevent prostate and thyroid cancer, hepatotoxicity, oxidative stress-induced cerebral injury, etc. This study was conducted to evaluate the effects of seven dibenzocyclooctadiene lignans of Schisandra chinensis and explore the possible mechanisms in the human neuroblastoma SH-SY5Y cells exposed on serum and glucose deprivation (SGD) injury. The structure-activity relationships were also analyzed.
METHODS AND RESULTS:
Cell viability and lactate dehydrogenase (LDH) release were determined to evaluate cell injury. Inflammation and apoptosis-related protein levels were detected to elucidate the possible mechanisms. Schisantherin A, Schizandrin C, and schizandrol B were found to have stronger protective effects than schizandrin A, schizandrin B, and schisanhenol in SH-SY5Y cells against SGD injury. Moreover, the protective effects of these lignans were possibly exhibited by regulating inflammation and apoptosis-related proteins in SH-SY5Y cells after SGD injury, supporting their beneficial effects for the prevention of cell injury in the pathogenesis of the central nervous system diseases, including ischemia stroke.
The number and position of hydroxyl group and methylenedioxy in these lignans may be required for their effects.

|Simultaneous determination of lignans and organic acids in Schisandrae Chinensis Fructus by UFLC-Q-TRAP-MS/MS.[Pubmed: 29933678]|
METHODS AND RESULTS:
An analytical method based on UFLC-QTRAP-MS/MS was developed for simultaneous determination of fifteen components including eleven lignans (schizantherin B, schisandrol B, Schizandrin C, γ-schisandrin, deoxyschizandrin, schisantherin, schisandrin, schisanhenol, gomisin D, gomisin J, and angeloylgomisin H) and organic acids (S)-malic acid, D(-)-tartaric acid, protocatechuic acid, and quinic acid) in Schisandrae Chinensis Fructus. Samples from different product specifications were evaluated and analyzed. The chromatographic separation was performed on a Synergi™ Hydro-RP 100Å column (2.0 mm×100 mm, 2.5 μm) at 40 °C with a gradient elution by employing 0.1% aqueous formic acid (A)-acetonitrile (B) as the mobile phase, and the flow rate was 0.4 mL·min⁻1, using an electrospray ionization (ESI) source and multiple reaction monitoring (MRM) mode. Fifteen components were evaluated synthetically by TOPSIS and gray related degree. The results showed that fifteen components had good linearity (r>0.999 90), and the limits of detection were all satisfactory. The average recoveries of standard addition for the compounds were between 95.42 % and 98.86 %, and the relative standard deviations were less than 5%. The greatest difference of ri in grey related degree was 58.1%, whilst the greatest difference of Ci value in TOPSIS method was 94.8%. The results of these two methods showed that the holistic quality of No. 14 sample was the best.
The developed method was accurate and reliable, which was suitable for the simultaneous determination of multiple functional substances and able to provide a new basis for the comprehensive assessment and overall control of the quality of Schisandrae Chinensis Fructus.
