Effects of taraxasterol on inflammatory responses in lipopolysaccharide-induced RAW 264.7 macrophages.[Pubmed:22366673]
J Ethnopharmacol. 2012 May 7;141(1):206-11.
AIM OF THE STUDY: Taraxasterol, a pentacyclic-triterpene, was isolated from the Chinese medicinal herb Taraxacum officinale. In the present study, we investigated the in vitro anti-inflammatory activity of Taraxasterol in lipopolysaccharide (LPS)-induced RAW 264.7 murine macrophages. MATERIALS AND METHODS: RAW 264.7 cells were pretreated with 2.5, 5, or 12.5mug/ml of Taraxasterol 1h prior to treatment with 1mug/ml of LPS. Nitric oxide (NO) level in supernatants from cells was examined by Griess reaction, the concentrations of prostaglandin E(2) (PGE(2)), tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and interleukin-6 (IL-6) were measured by ELISA. Nuclear factor kappa B (NF-kappaB) activation was evaluated by immunocytochemical analysis. RESULTS: We found that Taraxasterol inhibited NO, PGE(2), TNF-alpha, IL-1beta and IL-6 production in LPS-induced RAW 264.7 macrophages in a dose-dependent manner. Further studies revealed that Taraxasterol prevented the LPS-induced NF-kappaB translocation from cytoplasm into nuclear. CONCLUSIONS: These results indicate that Taraxasterol has anti-inflammatory effect by blocking NF-kappaB pathway.

Protective effect of taraxasterol against LPS-induced endotoxic shock by modulating inflammatory responses in mice.[Pubmed:24286370]
Immunopharmacol Immunotoxicol. 2014 Feb;36(1):11-6.
Taraxasterol, a pentacyclic-triterpene, was isolated from the Chinese medicinal herb Taraxacum officinale. In the present study, we investigated the protective effect of Taraxasterol on murine model of endotoxic shock and the mechanism of its action. Mice were treated with 2.5, 5 and 10 mg/kg of Taraxasterol prior to a lethal dose of lipopolysaccharide (LPS) challenge. Survival of mice was monitored twice a day for 7 days. To further understand the mechanism, the serum levels of inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and mediator nitric oxide (NO), prostaglandin E(2) (PGE(2)) as well as histology of lungs were examined. The results showed that Taraxasterol significantly improved mouse survival and attenuated tissue injury of the lungs in LPS-induced endotoxemic mice. Further studies revealed that Taraxasterol significantly reduced TNF-alpha, IFN-gamma, IL-1beta, IL-6, NO and PGE(2) levels in sera from mice with endotoxic shock. These results indicate that Taraxasterol has a protective effect on murine endotoxic shock induced by LPS through modulating inflammatory cytokine and mediator secretion. This finding might provide a new strategy for the treatment of endotoxic shock and associated inflammation.
