High-speed counter-current chromatography (HSCCC) was successfully applied to the preparative separation and purification of deoxyschisandrin and gamma-schisandrin from the crude petroleum ether extracts of Schisandra chinensis (Turcz.) Baill. The optimum solvent system composed of n-hexane-methanol-water (35:30:3, v/v) led to the successful preparation of deoxyschisandrin and gamma-schisandrin...
Schisandrin A is a bioactive lignan occurring in the fruits of plants of the Schisandra genus that have traditionally been used in Korea for treating various inflammatory diseases. Although the anti-inflammatory and antioxidant effects of lignan analogues similar to schisandrin A have been reported, the underlying molecular mechanisms have remained elusive. In the present study, schisandrin A s...
A new dibenzocyclooctene-type lignan, named schisandrin A1 (1), together with nine known lignans (2-10), was isolated from the stems of Schisandra sphenathera. The structure of schisandrin A1, which contains a spirocyclic epoxy unit, was established by means of spectroscopic methods. The absolute configurations of schisandrin A1 (1) and schisantherin A (2) were determined by electronic circular...
Dengue virus (DENV) infects 400 million people worldwide annually. Infection of more than one serotype of DENV highly corresponds to dengue hemorrhagic fever and dengue shock syndrome, which are the leading causes of high mortality. Due to lack of effective vaccines and unavailable therapies against DENV, discovery of anti-DENV agents is urgently needed. We first characterize that Schisandrin A...
