The effect of acanthoic acid analogs on the response to proinflammatory challenge was investigated. Some pimarane diterpenes are known activators of the LXRαβ nuclear receptors, but we show here that they also exert a rapid, potent, and selective activation of the p110γ and p110δ subunits of PI3K.
Periodontitis is a chronic disease that affects the gums and destroys connective tissue. Acanthoic acid (AA), a diterpene in Acanthopanax koreanum, has been reported to have anti-inflammatory activities. The aim of this study was to investigate the anti-inflammatory effects of AA on
Acanthoic acid, a pimaradiene diterpene isolated from Acanthopanax koreanum, has been reported to have anti-inflammatory activities. However, the effect of acanthoic acid on vascular inflammation has not been investigated. The aim of this study was to investigate the anti-inflammatory effects of
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 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
Syntheses and excellent anti-inflammatory effects of a series of novel acanthoic acid analogs are reported. In particular, the mechanistic basis for their anti-inflammatory effects is also described.
The synthesis and biological evaluation of a new family of diterpenes, represented by structures 2 and 3, is presented. These compounds constitute isomeric analogues of acanthoic acid (1) and were examined as potent anti-inflammatory agents. Among them, methyl ester 12 exhibited a low non-specific
Diterpene derivatives of the natural product acanthoic acid have potent anti-inflammatory effects in vivo. In this issue of Chemistry & Biolgy, Través and colleagues report that the primary molecular mechanism of action of diterpenes structurally related to acanthoic acid is the direct activation of
Acanthoic acid, a pimaradiene diterpene isolated from Acanthopanax koreanum, has been reported to have anti-inflammatory activities. However, the effects of acanthoic acid on LPS-induced acute lung injury have not been reported. The purpose of this study was to investigate the protective effect of
BACKGROUND
Intestinal epithelial cells (IECs) can produce cytokines and chemokines that play an important role in the mucosal immune response. Regulation of this production is important to prevent inflammatory tissue damage. The root and stem barks of Acanthopanax species have been used as a tonic
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,
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),
Acanthoic acid (AA) is a pimaradiene diterpene isolated from the Korean medicinal plant, Acanthopanax koreanum (Araliaceae). In the present study, we examined whether AA has the inhibitory effect on the production of inflammatory mediators and activating signals induced in trypsin-treated human
The aim of this study was to investigate the effects of acanthoic acid (AA) on the regulation of inflammatory response, lipid accumulation, and fibrosis via AMPK- IRAK4 signaling against chronic alcohol consumption in mice. Ethanol-induced liver injury was induced in male mice by Lieber-DeCarli diet
Acanthoic acid (AA) is a pimaradiene diterpene isolated from Acanthopanax koreanum Nakai (Araliaceae), with anti-inflammatory and hepatic-protective effects. The present study intended to reveal the effect and mechanism of AA on nonalcoholic fatty liver disease (NAFLD) associated with lipid
