The methanolic extract from the flowers of Helichrysum arenarium L. MOENCH was found to show inhibitory effect on tumor necrosis factor-alpha (TNF-alpha, 1 ng/ml)-induced cytotoxicity in L929 cells. From the methanolic extract, 50 constituents including four new flavanone and chalcone glycosides
The hepatotoxic effects of high-dose acetaminophen (400 and 600 mg/kg body weight) were evaluated by determining the glutathione (GSH) and malondialdehyde (MDA) levels and the histological changes in the liver at 6 and 12 h, using C57BL/6J mice. Massive centrilobular hepatocyte necrosis associated
Effects of 11 original glycoside derivatives of muramyl dipeptide on the production of interleukin-1 and tumor necrosis factor by mouse peritoneal macrophages were studied. The relationship between macrophage activation evaluated by induction of these cytokines and configuration of glycoside bond
OBJECTIVE
The aim was to determine the action mode of cornel iridoid glycoside (CIG) from Fructus corni on hepatoprotective activities, the effects of CIG on human hepatocyte cell line (L02) injured by D-galactosamine (GalN) and tumor necrosis factor-α (TNF-α) were examined.
METHODS
The percentage
OBJECTIVE
To investigate the possible mechanism of action of tripterygium glycosides (TG) for treatment of Behcet's disease (BD) through observing its effect on serum levels of interleukin-1beta (IL-1beta), interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-alpha) and interferon-gamma
Fagonia indica is a small spiny shrub of great ethnopharmacological importance in folk medicine. The aqueous decoction of aerial parts is a popular remedy against various skin lesions, including cancer. We used a biological activity-guided fractionation approach to isolate the most potent fraction
The main purpose of this study was to determine the subchronic effects of low concentrations of tumor necrosis factor alpha (TNF alpha) on the inotropic response and on the cellular level of high energy phosphates of cardiomyocytes. Therefore, the inotropic response of cultured neonatal rat heart
BACKGROUND
The flowers of Gentiana macrophylla have been usually applied to cure the joint inflammation and rheumatoid arthritis in Traditional Chinese Medicine.
OBJECTIVE
This work aimed to investigate the anti-rheumatoid arthritic effect and possible mechanism of iridoid glycosides from G.
Cardiac glycosides, which are inhibitors of Na(+)/K(+)-ATPase, are classified into cardenolides and bufadienolides. We have recently shown that two cardenolide glycosides, ouabain and odoroside A, inhibit Na(+)/K(+)-ATPase, thereby preventing nuclear factor κB-inducible protein expression by
Recent studies have demonstrated the tissue-specific effect of Na+/K+ pump inhibition by ouabain and other cardiac glycosides on cell viability. The vascular endothelium is an initial target of cardiac glycosides employed for the management of congestive heart failure as well as circulating
OBJECTIVE
To examine the course of chronic cardiac failure (CCF), morphofunctional parameters of the heart in correlation with activity of cytokine system; to evaluate effectiveness, tolerance and safety of combined CCF treatment including a cardioselective beta-adrenoblocker bisoprolol in patients
Quercetin (Que) is one of main compounds in Lysimachia christinae Hance (Christina loosestrife), and has both medicinal and nutritional value. Glycosides from Tripterygium wilfordii Hook.f. (léi gōng téng [the thunder duke vine]; TG) have diverse and broad bioactivities but with a high incidence of
Tripterygium glycosides (TG) are commonly used for basic medicine in curing rheumatoid arthritis but with a high incidence of liver injury. Geniposide (GP) has broad and diverse bioactivities, but until now it is still unknown whether GP can protect against TG-induced liver injury. This study, for
Five new phenylpropanoid glycosides, susaroysides A-E (1-5) were isolated from the fruits of Forsythia suspensa. Their structures were elucidated by comprehensive spectroscopic data analysis. The absolute configurations of their sugars were determined by GC analysis. Notably, susaroysides A-D
Recently, we have demonstrated the ability of naringin, a well-known flavanone glycoside of grapefruits and citrus fruits, to prevent neurodegeneration in a neurotoxin model of Parkinson's disease. Intraperitoneal injection of naringin protected the nigrostriatal dopaminergic projection by
