To investigate the mechanism underlying anti-inflammatory and immunoregulatory effect of total glucosides of paeony (TGP) based on toll-like receptor 2 (TLR2) mediated tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6)/nuclear factor-kappa B (NF-κB) pathway activation in Blueberries are rich in anthocyanins (ACNs), which have recently been noted to protect against atherosclerosis development in mice. Cyanidin-3-O-glucoside (C3G), a member of blueberry ACN family, can inhibit the tumor necrosis factor-α (TNF-α)-induced proliferation of vascular smooth muscle cells
Mangiferin, a natural polyphenol is known to exhibit anti-inflammatory, antioxidant, and antiviral effects. However the molecular mechanism underlying these effects has not been well characterized. Because NF-kappaB plays an important role in these processes, it is possible that mangiferin modulates
Anthocyanins are used for food color, and they are widely distributed in the human diets, suggesting that we ingest considerable amounts of anthocyanins from plant-based daily diets. We have demonstrated that a typical anthocyanin, cyanidin 3-O-beta-D-glucoside (C3G), suppressed the zymosan-induced
First attempts to discriminate between tapping panel dryness (TPD) and bark necrosis (BN), two Hevea sp. bark diseases leading to the cessation of latex production, showed differences in latex biochemical characteristics (1). Further, contrary to TPD, BN is characterized by inner phloem necrosis
Controversy exists over whether the predominant cell death of hepatocytes is due to apoptosis or necrosis after ischemia/reperfusion injury. In this study we investigated the predominant cell death of hepatocytes after cold ischemia/reperfusion injury using the Annexin V-based assay, and evaluated
Diabetic nephropathy (DN) is a common complication of diabetes and the major cause of chronic kidney disease. Cyanidin 3-glucoside (C3G) is the most widespread anthocyanin in nature. In the present study, we aimed to investigate the possible effects of C3G on DN in db/db mice. We found that body
Adipocyte dysfunction is strongly associated with the development of obesity and insulin resistance. It is accepted that the regulation of adipocytokine expression is one of the most important targets for the prevention of obesity and improvement of insulin sensitivity. In this study, we have
The purpose of this study was to evaluate the response of estrogen target cells to a series of isoflavone glucosides and aglycones from Genista halacsyi Heldr. The methanolic extract of aerial parts of this plant was processed using fast centrifugal partition chromatography, resulting in isolation
Tetrahydroxystilbene glucoside (THSG) is one of the active ingredients of Polygonum multiflorum. It has been shown to exert a variety of pharmacological effects, including antioxidant, anti-aging, and anti-atherosclerosis. Because of its prominent anti-inflammatory effect, we explored whether THSG
Although numerous hypotheses have been raised in recent years, the exact mechanisms that promote the development of major depression are largely unknown. Recently, strategies targeting the process of neuroinflammation and oxidative stress in depression have been attracting greater attention. 2, 3,
Total glucosides of paeony (TGP) are active compounds extracted from the roots of Paeonia lactiflora Pall. In this study, we investigated the mechanisms of total glucosides of paeony (TGP) in the treatment of adjuvant arthritis (AA). AA in rats was established. Synoviocytes proliferation and
1. Paeoniflorin is one of the main effective components of the total glucosides of paeony (TGP) extracted from the root of Paeonia lactiflora which has been used for gynaecological problems and for cramp, pain and giddiness for over 1,500 years in Chinese medicine. Anti-inflammatory, antioxidative,
The bioassay-guided fractionation of preventive agents against lethality due to septic shock from the fruits of Illicium verum led to the isolation of two known racemic mixtures of phenylpropanoids, [1-(4'-methoxyphenyl)-(1 R,2 S and 1 S,2 R)-propanediol (1) and 1-(4'-methoxyphenyl)-(1 R,2 R and 1
This study hypothesized that the predominant strawberry anthocyanin, pelargonidin-3-O-glucoside (Pg-3-glc), and 3 of its plasma metabolites (4-hydroxybenzoic acid, protocatechuic acid, and phloroglucinaldehyde [PGA]) would affect phagocytosis, oxidative burst, and the production of selected pro- and
