Evaluation of sage phenolics for their antileishmanial activity and modulatory effects on interleukin-6, interferon and tumour necrosis factor-alpha-release in RAW 264.7 cells.

Only registered users can translate articles

A series of sage phenolics was tested for activity against a panel of Leishmania parasites and for immunomodulatory effects on macrophage functions including release of tumour necrosis factor (TNF), interleukin-6 (IL-6), and interferon (IFN)-like activities. For this, functional bioassays were

Chemoprotection by phenolic antioxidants. Inhibition of tumor necrosis factor alpha induction in macrophages.

Only registered users can translate articles

Phenolic antioxidants exhibit anti-inflammatory activity in protection against chemical toxicity and cancer. To investigate the molecular mechanism of anti-inflammation, we analyzed the regulation of tumor necrosis factor alpha (TNF-alpha) expression in macrophages, a key step in inflammation, by

Effects of anthocyanins and other phenolic compounds on the production of tumor necrosis factor alpha in LPS/IFN-gamma-activated RAW 264.7 macrophages.

Only registered users can translate articles

Flavonoids have been reported to demonstrate their benefits in lowering oxidative stress and beneficial effects on cardiovascular and chronic inflammatory diseases. Common phenolic compounds, including phenolic acids, flavonols, isoflavones, and anthocyanins, present in fruits, vegetables, and

Phenolic compounds isolated from Dioscorea zingiberensis protect against pancreatic acinar cells necrosis induced by sodium taurocholate.

Only registered users can translate articles

One new bibenzyl (1) and one new phenanthrene (2), together with two known bibenzyls (3-4) and four known diarylheptanoids (5-8) were isolated from the rhizomes of Dioscorea zingiberensis. The structures of 1-2 were elucidated by spectroscopic methods including 1D and 2D NMR. Phenols 1-8 were

Effect of unique Mycobacterium leprae phenolic glycolipid-I (PGL-I) on tumour necrosis factor production by human mononuclear cells.

Only registered users can translate articles

Mycobacterium leprae cell wall-associated components are found in large amounts in the tissues of leprosy patients, particularly those at the lepromatous pole. Among these molecules, the phenolic glycolipid-I (PGL-I), unique to M. leprae, has been involved in the selective anergy observed in the

Effect of Selected Pyrazine Derivatives on the Production of Phenolics and Rutin in Urtica dioica and Fagopyrum esculentum.

Only registered users can translate articles

The effect of four pyrazine derivatives on the content of phenolic compounds in Urtica dioica L. and rutin in Fagopyrum esculentum Moench was studied. Pyrazine derivatives H1 and H2 were used on U. dioica, and derivatives S1 and S2 on F. esculentum, both separately and in combination with urea. The

Antioxidative and oxidative changes in the digestive gland cells of freshwater mussels Unio tumidus caused by selected phenolic compounds in the presence of H(2)O(2) or Cu(2+) ions.

Research on biomarkers as early bioindicators of perturbation in populations and individuals has received increasing interest during recent decades. These ecotoxicity studies allow us to measure the impact of environmental stressors and to monitor and evaluate the degradation or restoration of

Ultrasonically-Assisted and Conventional Extraction from Erodium Glaucophyllum Roots Using Ethanol:Water Mixtures: Phenolic Characterization, Antioxidant, and Anti-Inflammatory Activities.

Only registered users can translate articles

The paper presents experimental results concerning the ultrasonically-assisted extraction of bioactive compounds from Erodium glaucophyllum roots. A comparison with conventional methodology is presented, and thereby the phytochemical composition and the antioxidant and anti-inflammatory

Bioactive triterpenoid saponins and phenolic compounds against glioma cells.

Only registered users can translate articles

A total of 54 natural origin compounds were evaluated for their activity in inhibiting the proliferation of glioma cells. Results showed that four Aesculus polyhydroxylated triterpenoid saponins (3-6), six Gleditsia triterpenoid saponins (7-12), and five phenolic compounds (43-46, 51) had

Renal cortical necrosis following exposure to sap of the marking-nut tree (Semecarpus anacardium).

Only registered users can translate articles

An 18-year-old man developed skin lesions and anuria following exposure to sap of the marking-nut tree (Semecarpus anacardium). Renal biopsy showed diffuse cortical necrosis. The mechanism of nephrotoxicity of the sap is unknown but may be due to its phenolic constituents.

Divergent immunomodulatory effects of extracts and phenolic compounds from the fern Osmunda japonica Thunb.

Only registered users can translate articles

OBJECTIVE To study possible immunobiological potential of Osmunda japonica Thunb. METHODS Immunomodulatory effects of ethanol extracts prepared from rhizomes of O. japonica and phenolic compounds isolated from the extracts were investigated under the in vitro conditions using the rat peritoneal

Antioxidant and Anti-Inflammatory Activities of Phenolic-Enriched Extracts of Smilax glabra.

Only registered users can translate articles

Smilax glabra Roxb. has been used for a long time as both food and folk medicine. In the present study, phenolic-enriched extract of S. glabra (PEESG) was extracted with 70% ethanol and purified by HP-20 column chromatography. Its antioxidant and anti-inflammatory activities were evaluated by

Soluble Phenolic Composition Tailored by Germination Conditions Accompany Antioxidant and Anti-inflammatory Properties of Wheat

Only registered users can translate articles

Knowledge on the specific variation in the phenolic composition of wheat defined by germination conditions and its relationship with antioxidant and anti-inflammatory properties of sprouts would be useful to improve the functional value of wheat-derived products. Variation in soluble phenolic
