The objective of this study was to assess whether tyrosol and caffeic acid are able to inhibit lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-alpha release. TNF is one of the most important cytokines involved in inflammatory reactions. The results show that both tyrosol and caffeic
Tyrosol (Tyr) is a natural phenolic antioxidant with diverse biological activities. We compared the anti-inflammatory effects of intravenously administered Tyr versus prednisolone (PSL) in an endotoxin-induced uveitis (EIU) rat model. Intravenous administration of 100 mg/kg Tyr was performed 2 hr
The effects of p-tyrosol and Rhodiola rosea extract on the hemopoietic system were compared on a model of subacute lead intoxication. No significant differences between the activity of two preparations were revealed by the study of plasma membrane blebbing, apoptosis, and necrosis processes in bone
Tyrosol, a phenolic compound, was isolated from wine, olive oil and other plant-derived products. In the present study, we first investigated the negative regulatory effects of tyrosol on cytokine production by lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages in vitro, and the results
Intervertebral disc degeneration (IDD) is the major pathogenesis of lower back pain. Tyrosol is a polyphenolic compound that exhibits anti-oxidant, anti-apoptotic, and anti-inflammatory effects. Herein, we explored the effects and mechanisms of tyrosol on IDD progression in interleukin
We evaluated the anti-inflammatory effect of tyrosol (Tyr) on endotoxin-induced uveitis (EIU) in rats. EIU was induced in male Lewis rats by subcutaneous injection of lipopolysaccharide (LPS). Tyr (10, 50 or 100 mg/kg) was intravenously injected 2 hr before, simultaneously and 2 hr after LPS
Acute lung injury (ALI) is a life-threatening disease characterized by increased pulmonary vascular permeability because of alveolar capillary barrier dysfunction and increased immune responses. This study determined the anti-inflammatory effect of tyrosol on lipopolysaccharide (LPS)-induced ALI and
The established causal relationship between the chronic inflammatory microenvironment, tumor development and cancer recurrence has provided leads for developing novel preventive strategies. Accumulating experimental, clinical and epidemiological data has provided support for the chemopreventive
Candida lusitaniae is an emerging opportunistic yeast and an attractive model to discover new virulence factors in Candida species by reverse genetics. Our goal was to create a dpp3Δ knockout mutant and to characterize the effects of this gene inactivation on yeast in vitro and in vivo interaction
Some well-known antioxidant phenols present in extravirgin olive oil have also been found in white wine. Both tyrosol and caffeic acid are phenols that are present not only in extravirgin olive oil, but also in wine, especially white wine. Their antioxidant properties are well known, but their
Activity-guided isolation of compounds from the fruits of Amomum xanthioides resulted in the purification of fourteen phenolic compounds, 4-hydroxy-benzaldehyde (1), 3,4-dihydroxybenzaldehyde (2), 3,5-dimethoxy-4-methylbenzaldehyde (3), syringic aldehyde (4), benzoic acid (5), 3,4-dihydroxy benzoic
Oxidative stress and inflammatory responses sustained for a long period of time cause many diseases. A proinflammatory cytokine, tumor necrosis factor α (TNF-α), plays a pivotal role in the pathogenesis of chronic and auto-immune diseases. The present review, supplemented by hitherto unpublished
Ascochyta lentis var. lathyri has recently been reported to be the causal agent of Ascochyta blight of grass pea ( Lathyrus sativus), a disease characterized by the appearance of necrotic lesions of leaves and stems. Considering the novelty of the pathogen and the possible involvement of secondary
Two phytotoxic furan derivatives were isolated, together with the well-known fungal and plant phytotoxin tyrosol, from the culture filtrates of Stilbocrea macrostoma. This fungal pathogen isolated from Quercus brantii trees induced wood necrosis and decline symptoms on the host plant
Anoxia modulates the expression of molecules associated with endothelial dysfunction and vascular diseases. Polyphenols have potent antioxidant properties due to their ability to modulate genes involved in oxidative tissue damage. In this study, we investigated the effect of polyphenol extract from
