Lignans are imporant active ingredients of Schisandra sphenanthera. A micellar electrokinetic chromatography method was developed for the simultaneous determination of eight lignans--schizandrin, schisandrol B, schisantherin A, schisanhenol, anwulignan, deoxyschizandrin, schizandrin B and
A simple and sensitive high performance liquid chromatography method with photodiode array detection (HPLC-DAD) was developed for simultaneous determination of eight bioactive constituents (schisandrin, schisandrol B, schisantherin A, schisanhenol, anwulignan, deoxyshisandrin, schisandrin B and
We recently reported that Wuzhi tablet (WZ; Schisandra sphenanthera extract) can inhibit P-glycoprotein (P-gp)-mediated efflux and CYP3A-mediated metabolism of tacrolimus (FK506) and thus increase the blood concentrations of FK506. Major active lignans of WZ include schisandrin A, schisandrin B,
Liver regeneration is a vital process of recovery after liver damage, which is a promising clinical strategy after partial hepatectomy (PHx). Schisandrol B (SolB), one of the bioactive ingredients from Schisandra sphenanthera, displays significant hepato-protection effects against drug-induced liver
Twenty Schisandra samples were collected from different locations. Contents of 7 lignans in the samples were determined and analyzed by HPLC method coupled with hierarchical clustering analysis (HCA) and principal component analysis (PCA), and the antioxidant capacity of Schisandra from the
Acetaminophen (APAP) overdose is the most frequent cause of drug-induced acute liver failure. Schisandra sphenanthera is a traditional hepato-protective Chinese medicine and Schisandrol B (SolB) is one of its major active constituents. In this study, the protective effect of SolB against
We recently reported that Wuzhi tablet (WZ), a preparation of the ethanol extract of Wuweizi (Schisandra sphenanthera), had significant effects on blood concentrations of Tacrolimus (FK506) in renal transplant recipients and rats. The active lignans in WZ are schisandrin A, schisandrin B,
OBJECTIVE
The nuclear factor erythroid 2-related factor 2 (NRF2) acts through the antioxidant response element (ARE) to regulate the expression of many detoxifying and antioxidant genes responsible for cytoprotective processes. We previously reported that Schisandrol B (SolB) isolated from
Currently, ursodeoxycholic acid and obeticholic acid are the only two FDA-approved drugs for cholestatic liver diseases. Thus, new therapeutic approaches need to be developed. Here we have evaluated the anti-cholestasis effects of Schisandrol B (SolB), a bioactive compound isolated from Schisandra
This study aimed to investigate the potential interaction between Schisandra sphenanthera, imatinib and bosutinib combining in vitro and in silico methods.In vitro metabolism of imatinib and bosutinib using recombinant enzymes and human liver microsomes Cholestasis is a clinical syndrome caused by toxic bile acid retention that will lead to serious liver diseases. Ursodeoxycholic acid (UDCA) and obeticholic acid (OCA) are the only two FDA-approved drugs for its treatment. Thus, there is a clear need to develop new therapeutic The fruit of S. sphenanthera, known as "Nanwuweizi", has been widely used as traditional Chinese medicine for several thousand years. However, the current determination methods are not sufficient to evaluate its quality. An accurate, sensitive and reliable high performance liquid chromatography
Tacrolimus is widely used for kidney transplantation in children. However, the narrow therapeutic window and considerable interindividual and intraindividual variabilities make tacrolimus untoward to design an optimum dosage for paediatric personalized medicine. Our research aims to This study was aimed to determine the hepatic and small intestinal distribution of active lignans in rats after treated with Wuzhi tablet (WZ, Schisandra sphenanthera extract) by LC-MS/MS method. Male Sprague-Dawley rats were sacrificed at 0.25, 1.5, 4, 6, 10, 24 h after an oral administration of
