Several topical formulations containing methanolic extract of Siegesbeckia pubescens was investigated for antiinflammatory and analgesic activities in rat. The effects were studied using carrageenan-induced edema and formalin testing. Piroxicam gel and methyl salicylate ointment were studied as
Nine new ent-pimarane-type diterpenoids, siegesbeckia A-I (1-9), together with four known analogues ent-3α,15,16,19-tetrahydroxypimar-8(14)-ene (10), 15,16-dihydroxypimar-8(14)-en-3-one (11), 14β,16-epoxy-7-pimarene-3α,15β-diol (12) and darutigenol (13), were obtained from the aerial parts of
Seven rare oxylipins, siegesbeckins A-G (1-7) representing further bioactive constituents different from the general terpenyl compounds found in Siegesbeckia species, have been obtained from the aerial parts of Siegesbeckia glabrescens. These isolates were identified to be a series of methyl
BACKGROUND
Siegesbeckia orientalis has been traditionally used as a topical anti-inflammatory and analgesic agent.
OBJECTIVE
Current study was designed to explore the topical anti-inflammatory and analgesic effects of a constituent isolated from Siegesbeckia orientalis (Compositae), in order to
A new sesquiterpene lactone was isolated from Siegesbeckia glabrescens as an inhibitor of nitric oxide and prostaglandin E2 synthesis in the LPS-activated RAW264.7 macrophage cell line. It dose-dependently decreased the protein and mRNA levels of inducible nitric oxide synthase and cyclooxygenase-2.
This study aims to investigate the PPARγ agonists isolated from the aqueous extract of Siegesbeckia pubescens( SPA) and their anti-inflammatory activities in vitro. The 293 T cells transfected transiently with PPARγ recombinant plasmid were used as a screening model to guide the isolation of PPARγ
Four flavones, 3,4'-O-dimethylquercetin (1), 3,7-O-dimethylquercetin (2), 3-O-methylquercetin (3) and 3,7,4'-O-trimethylquercetin (4) were isolated as the inhibitors of nitric oxide production in activated microglia (IC(50) values: 11.1, 4.2, 3.8, and 25.1 microM, respectively). They suppressed the
Oxidative stress imposed by reactive oxygen species plays a crucial role in pathophysiology of inflammatory diseases. In the present study, sesquiterpenoids and diterpenoids isolated from Siegesbeckia pubescens, a Chinese traditional medicine used to treat arthritis, were evaluated for inhibition of
This study aims to investigate the anti-inflammatory responses and mechanisms of Siegesbeckia orientalis ethanol extract (SOE). In cell culture experiments, RAW264.7 cells were pretreated with SOE and stimulated with lipopolysaccharide (LPS) for inflammatory mediators assay. In animal experiments,
Siegesbeckia orientalis has been reported to exhibit anti-allergic, anti-infertility, anti-inflammatory, anti-rheumatic, and immunosuppressive activities. However, there are very few studies describing its stimulatory effects on exercise capacity. This study elucidated whether S.
Siegesbeckia orientalis L. is an annual herb widely distributed throughout the world and has many medicinal properties. In Chinese traditional system, it is popularly known as Xi-Xian and used for its anti-inflammatory properties. In the present study, two cytotypes (diploid and tetraploid) have
BACKGROUND
The medicinal plant Siegesbeckia orientalis L. has been commonly used for the treatment of acute arthritis, rheumatism, and gout in Vietnam. However, pharmacological research of this plant associated with gout has not been reported. Anti-hyperuricemic and anti-inflammatory effects were
UNASSIGNED
Siegesbeckia pubescens Makino (SP) is one of the important plant origins for the anti-inflammatory Chinese herbal medicine of Siegesbeckiae Herba. The current investigations indicated that the anti-inflammatory effects of SP were associated with the toll-like receptors (TLRs)-mediated
Ethnopharmacological relevance: The Chinese traditional medicine of Siegesbeckia pubescens Makino (SM), which has the effect of healing rheumatism and promoting joint health, is often used to treat rheumatoid arthritis and ischemic
