Interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) are major proinflammatory cytokines inducing the synthesis and release of many inflammatory mediators. They are involved in immune regulation, autoimmune diseases, and inflammation. Acanthoic acid, (-)-pimara-9(11),15-dien-19-oic acid,
The hepatoprotective effects of a diterpenoid acanthoic acid isolated from Acanthopanax koreanum NAKAI were evaluated in a D-galactosamine/lipopolysaccharide-induced fulminant hepatic failure mouse model. Mice were pretreated orally with acanthoic acid 12 and 1 h before intraperitoneal injection of
The aim of this study was to investigate the protective effect of acanthoic acid, a diterpene isolated from the root bark of Acanthopanax koreanum, on liver injury induced by either tert-butyl hydroperoxide (tBH) or carbon tetrachloride in vitro and in vivo. In vitro, the cellular leakage of lactate
The protective effect of a diterpenoid acanthoic acid (AA) isolated from Acanthopanax koreanum Nakai was investigated in acetaminophen (APAP)-induced hepatic toxicity. Drug-induced hepatotoxicity induced by an intraperitoneal (i.p.) injection of 300mg/kg (sub-lethal dose) of APAP. Pretreatment with
Tumour necrosis factor-alpha (TNF-alpha) is a major pro-inflammatory cytokine inducing the synthesis and release of many inflammatory mediators. It is involved in immune regulation, autoimmune diseases, and inflammation. Our previous study demonstrated that acanthoic acid, (-)-pimara-9(11),
Liver X receptors (LXRs)-mediated signals in acanthoic acid (AA) ameliorating liver fibrosis were examined in carbon tetrachloride (CCl4)-induced mice and TGF-β stimulated hepatic stellate cells (HSCs). AA was isolated from the root of Acanthopanax koreanum Nakai (Araliaceae). CCl4-treated mice were
Aims: The present study aims to detect the effect of acanthoic acid (AA) on alcohol exposure-induced liver lipid deposition and inflammation, and to explore the mechanisms. Methods: C57BL/6 mice were pretreated with single dose of AA (20 and 40 mg/kg) by oral gavage or equal volume of saline, and
The hepatoprotective activity of Acanthopanax koreanum Nakai extract (AE) was investigated against D-Galactosamine/Lipopolysaccharide (D-GalN/LPS)-induced liver failure rats compared with that of acanthoic acid (AA) isolated from AE. Although D-GalN/LPS (250 mg/kg body weight/10 µg/kg body weight,
