The biotransformation of swertiamarin [1, a seco-iridoid glucoside isolated from Swertia japonica (Schult.) Makino] by human intestinal bacteria was investigated. Three metabolites were isolated and identified as erythrocentaurin (2), 5-hydroxymethylisochroman-1-one (3), and gentianine (4) by
OBJECTIVE
To study the metabolism of total terpene ketones from Swertia mussotii with human intestinal bacteria.
METHODS
Total terpene ketones were incubated with human intestinal bacteria under an anaerobic environment and at 37 degrees C. The metabolites were extracted by ethyl acetate processing,
Chemical constituents of Swertia patens. The whole plant of air-dried Swertia patens was extracted with 90% EtOH. The water extract was suspended in H₂O and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isola- ted and purified by column chromatography from the
Dexamethasone (DEX) an anti-inflamatory 9-fluoro-glucocorticoid, activates the cytosolic glucocorticoid receptor (GR) binding to its Ligand Binding Domain (LBD). The GR-ligand complex then translocates to the nucleus and binds to the Glucocorticoid Response Element (GRE) resulting up-regulation of
