title: Liquiritigenin derivatives and their hepatotoprotective activity.
abstract: Liquiritigenin (7,4'-dihydroxyflavanone), isolated from the roots of Glycyrrhiza glabra, was derivatized to liquiritigenin 7, 4'-diacetate, liquiritigenin 4'-acetate, isoliquiritigenin, and liquiritigenin 7, 4'-dibenzoate. All these derivatives were evaluated for in vitro hepatoprotective activity against D-galactosamine-lipopolysaccharide(GalN/LPS) induced toxicity. In-vitro hepatotoxicity was manifested by a significant increase (P < 0.05) in liver toxicity biomarkers (SGPT, SGOT, ALKP, triglyceride, LPO, NO and LDH). The level of biomarkers in the treatment groups was significantly decreased (P < 0.05) when compared with the GalN/LPS group. The results revealed that isoliquiritigenin exhibited better hepatoprotective activity than liquiritigenin and its derivatives.
