Suppression of inducible nitric oxide synthase and cyclooxygenase-2 expression by tussilagone from Farfarae flos in BV-2 microglial cells.[Pubmed:18481023]

Arch Pharm Res. 2008 May;31(5):645-52.

Activated microglia produce diverse neurotoxic factors such as nitric oxide (NO) and prostaglandin E(2) (PGE(2)) that may cause neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease. From the EtOAc soluble fraction of Farfarae flos (Tussilago farfara), we purified Tussilagone as a bioactive compound by monitoring the inhibitory potential of NO production in activated microglia through the purification procedures. Tussilagone showed dose-dependent inhibition of NO and PGE(2) production in LPS-activated microglia with IC(50) values of 8.67 microM and 14.1 microM, respectively. It suppressed the expression of protein and mRNA of inducible nitric oxide synthase and cyclooxygenase-2 through the inhibition of 1-kappaBalpha degradation and nuclear translocation of p65 subunit of NF-kappaB. Therefore Tussilagone from Farfarae flos may have therapeutic potential in the treatment of neuro-inflammatory diseases through the inhibition of overproduction of NO and PGE(2).

The anti-inflammatory effect of tussilagone, from Tussilago farfara, is mediated by the induction of heme oxygenase-1 in murine macrophages.[Pubmed:19800419]

Int Immunopharmacol. 2009 Dec;9(13-14):1578-84.

Tussilagone (TSL), isolated from the flower of buds of Tussilago farfara (Compositae), is a sesquiterpenoid that is known to exert a variety of pharmacological activities. In the present study, we demonstrated that TSL exerts anti-inflammatory activities in murine macrophages by inducing heme oxygenase-1 (HO-1) expression. Treatment of RAW264.7 cells with TSL-induced HO-1 protein expression in a dose- and time-dependent manner without the induction of HO-1 mRNA expression. TSL-mediated HO-1 protein induction was not inhibited by treatment with actinomycin D, a transcriptional inhibitor, but by cycloheximide, a translational inhibitor. Moreover, mitogen-activated protein kinases (MAPKs) inhibitors such as SB203580, SP600125, and U0126 did not block TSL-mediated HO-1 protein expression, suggesting that the TSL-mediated HO induction may be regulated at the translational level. Consistent with the notion that HO-1 has anti-inflammatory properties, TSL inhibited the production of nitric oxide (NO), tumor necrosis factor (TNF)-alpha, and prostaglandin E2 (PGE2) as well as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and murine peritoneal macrophages. Inhibition of HO-1 activity by treatment with zinc protoporphyrin IX (ZnPP), a specific HO-1 inhibitor, abrogated the inhibitory effects of TSL on the production of NO and PGE2 in LPS-stimulated RAW264.7 cells. Taken together, TSL may be an effective HO-1 inducer that has anti-inflammatory effects, and a valuable compound for modulating inflammatory conditions.

Tussilagone inhibits dendritic cell functions via induction of heme oxygenase-1.[Pubmed:25091622]

Int Immunopharmacol. 2014 Oct;22(2):400-8.

Sesquiterpenoid Tussilagone (TUS) has a variety of pharmacological activities, such as anti-oxidant, anti-cancer, and anti-inflammatory activities. In this study, we investigated the effects of TUS on dendritic cell (DC) functions and the underlying mechanisms. TUS inhibited lipopolysaccharide (LPS)-induced activation of DCs, as shown by decrease in surface molecule expression, cytokine production, cell migration, and allo-T cell activation. In addition, TUS inhibited LPS-induced activation of NF-kappaB, MAPKs, and IRF-3 signalings in DCs, although it did not directly affect kinase activities of IRAK1/4, TAK1, and IKK, which suggests that TUS might indirectly inhibit TLR signaling in DCs. As a critical mechanism, we showed that TUS activated heme oxygenase-1 (HO-1), which degrades heme to immunosuppressive products, such as carbon monoxide and bilirubin. HO-1 inhibitor reversed the inhibitory activity of TUS in DCs. In conclusion, this study suggests that TUS inhibits DC function through the induction of HO-1.

Tussilagone suppresses colon cancer cell proliferation by promoting the degradation of beta-catenin.[Pubmed:24269588]

Biochem Biophys Res Commun. 2014 Jan 3;443(1):132-7.

Abnormal activation of the Wnt/beta-catenin signaling pathway frequently induces colon cancer progression. In the present study, we identified Tussilagone (TSL), a compound isolated from the flower buds of Tussilago farfara, as an inhibitor on beta-catenin dependent Wnt pathway. TSL suppressed beta-catenin/T-cell factor transcriptional activity and down-regulated beta-catenin level both in cytoplasm and nuclei of HEK293 reporter cells when they were stimulated by Wnt3a or activated by an inhibitor of glycogen synthase kinase-3beta. Since the mRNA level was not changed by TSL, proteasomal degradation might be responsible for the decreased level of beta-catenin. In SW480 and HCT116 colon cancer cell lines, TSL suppressed the beta-catenin activity and also decreased the expression of cyclin D1 and c-myc, representative target genes of the Wnt/beta-catenin signaling pathway, and consequently inhibited the proliferation of colon cancer cells. Taken together, TSL might be a potential chemotherapeutic agent for the prevention and treatment of human colon cancer.

Description

Tussilagone, a major active component in Tussilago farfara, has anti-inflammatory effect. Tussilagone ameliorates inflammatory responses in dextran sulphate sodium-induced murine colitis. Tussilagone inhibits the inflammatory response and improves survival in cecal ligation and puncture (CLP)-induced septic mice.
