Eudesmane-type sesquiterpene lactones inhibit multiple steps in the NF-κB signaling pathway induced by inflammatory cytokines.

Numai utilizatorii înregistrați pot traduce articole

Inflammatory cytokines, such as interleukin-1α (IL-1α) and tumor necrosis factor-α (TNF-α), induce the intracellular signaling pathway leading to the activation of nuclear factor κB (NF-κB). A series of eudesmane-type sesquiterpene lactones possessing an α-methylene γ-lactone group and/or an α-bromo

Guaianolides and a seco-Eudesmane from the Resinous Exudates of Cushion Bush (Leucophyta brownii) and Evaluation of Their Cytostatic and Anti-inflammatory Activity.

Numai utilizatorii înregistrați pot traduce articole

A detailed phytochemical investigation of a dichloromethane extract of the resinous exudates of the cushion bush plant (Leucophyta brownii) resulted in the isolation of the new 8,12-guaianolides leucophytalins A (5) and B (6), the new 1,10-seco-eudesmane leucophytalin C (10), six rare

Anti-inflammatory Activity of Eudesmane-Type Sesquiterpenoids from Salvia plebeia.

Numai utilizatorii înregistrați pot traduce articole

Nine new sesquiterpenoid lactones and 11 known analogues were isolated from the aerial parts of Salvia plebeia R.Br. Their structures were elucidated via HRESIMS and NMR data, and their absolute configurations were defined via electronic circular dichroism data, X-ray crystallographic analysis, and

New guaiane, megastigmane and eudesmane-type sesquiterpenoids and anti-inflammatory constituents from Youngia japonica.

Numai utilizatorii înregistrați pot traduce articole

Eleven sesquiterpenoids have been isolated from the whole plants of Youngia japonica (Asteraceae). Among these sesquiterpenoids, five were identified as new compounds on the basis of spectroscopic methods and chemical analysis. Their structures were

Eudesmane-Type Sesquiterpene Lactones Inhibit Nuclear Translocation of the Nuclear Factor κB Subunit RelB in Response to a Lymphotoxin β Stimulation.

Numai utilizatorii înregistrați pot traduce articole

The transcription factor nuclear factor κB (NF-κB) regulates various biological processes, including inflammatory responses. We previously reported that eudesmane-type sesquiterpene lactones inhibited multiple steps in the canonical NF-κB signaling pathway induced by tumor necrosis factor-α and

Anti-inflammatory sesquiterpenoids from the Traditional Chinese Medicine Salvia plebeia: Regulates pro-inflammatory mediators through inhibition of NF-κB and Erk1/2 signaling pathways in LPS-induced Raw264.7 cells.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Salvia plebeia R. Brown, a traditional Chinese medicinal herb, has been used to treat inflammatory diseases such as cough, hepatitis, and diarrhea for a long history. OBJECTIVE The aim of the present study was to isolate and identify potential anti-inflammatory agents from the herb of S.

A eudesmane-type sesquiterpene isolated from Pluchea odorata (L.) Cass. combats three hallmarks of cancer cells: Unrestricted proliferation, escape from apoptosis and early metastatic outgrowth in vitro.

Pluchea odorata is ethno pharmaceutically used to treat inflammation-associated disorders. The dichloromethane extract (DME) was tested in the carrageenan-induced rat paw oedema assay investigating its effect on inflammation that was inhibited by 37%. Also an in vitro anti-neoplastic potential was

Two New Eudesmane Sesquiterpenoids from the Flowers of Chrysanthemum indicum.

Numai utilizatorii înregistrați pot traduce articole

The flowers of Chrysanthemum indicum, i.e. Ye-ju-hua recorded in the Chinese Pharmacopoeia, has been widely used in China as an important heat-clearing and detoxifying herb for the treatment of inflammation, headache, and vertigo. A phytochemical investigation of this herb has led to the isolation

Five new eudesmane-type sesquiterpenoid lactones biotransformed from atractylenolide I by rat hepatic microsomes.

Numai utilizatorii înregistrați pot traduce articole

The work presented here is the first study performed on the biotransformation and/or metabolism of atractylenolide I (1) as a valuable anti-inflammatory and chemopreventive agent, using liver microsomes from rats pre-treated with sodium phenobarbital. Two known eudesmane-type sesquiterpenoid

Isolation of eudesmanes from Pluchea odorata and evaluation of their effects on cancer cell growth and tumor invasiveness in vitro.

Numai utilizatorii înregistrați pot traduce articole

The traditionally used Central American medicinal plant Pluchea odorata, known as an anti-inflammatory and cancer cell growth-inhibiting remedy, was subjected to bioassay-guided isolation. Structure elucidation by 1D- and 2D-NMR and MS techniques supported by ECD and UV spectroscopic data revealed

Further sesquiterpenoids from the rhizomes of Homalomena occulta and their anti-inflammatory activity.

Numai utilizatorii înregistrați pot traduce articole

The rhizomes of Homalomena occulta are called Qian-nian-jian in Traditional Chinese Medicine (TCM), which is widely consumed in China owing to its health benefits for the treatment of rheumatoid arthritis and for strengthening tendons and bones. A phytochemical investigation on this famous TCM

Structurally diverse sesquiterpenoids from the aerial parts of Artemisia annua (Qinghao) and their striking systemically anti-inflammatory activities

Numai utilizatorii înregistrați pot traduce articole

Thirteen new sesquiterpenoids, arteannoides F-R (1-13), along with 13 known analogues (14-26), were isolated from the dried aerial parts of Artemisia annua L. Their structures, including absolute configurations, were unambiguously determined by a combination of physical data analyses (HRESIMS, 1D

Two natural eudesmane-type sesquiterpenes from Laggera alata inhibit angiogenesis and suppress breast cancer cell migration through VEGF- and Angiopoietin 2-mediated signaling pathways.

Numai utilizatorii înregistrați pot traduce articole

Eudesmane-type sesquiterpenes are natural sesquiterpenes with anti-inflammatory properties, but their anti-angiogenic activities are not known. The present study demonstrated that 5α-hydroxycostic acid and hydroxyisocostic acid, two eudesmane-type sesquiterpenes (ETSs), isolated from the herb
