Urolithin B is one of the gut microbial metabolites of ellagitannins and is found in diverse plant foods, including pomegranates, berries, walnuts, tropical fruits, and medicinal herbs. Although a number of biological activities of urolithin B have been reported, the anti-inflammatory Urolithins are gut microbial metabolites derived from ellagitannins (ET) and ellagic acid (EA), and shown to exhibit anticancer, anti-inflammatory, anti-microbial, anti-glycative and anti-oxidant activities. Similarly, the parent molecules, ET and EA are reported for their neuroprotection and
Pomegranate ellagitannins (ETs) are transformed in the gut to ellagic acid (EA) and its microbiota metabolites, urolithin A (Uro-A) and urolithin B (Uro-B). These compounds exert anti-inflammatory effects in vitro and in vivo. The aim of this study was to investigate the effects of Uro-A, Uro-B, and
Ellagitannin-rich products exhibit beneficial influence in the case of inflammation-associated diseases. Urolithins, metabolites of ellagitannins produced by gut microbiota, in contrary to high molecular weight hydrophilic parental polyphenols, possess well established bioavailability. Because of
Ellagic acid (EA) is a component of ellagitannins, present in crops such as pecans, walnuts, and many berries, which metabolized by the gut microbiota forms urolithins A, B, C, or D. In this study, ellagic acid, as well as urolithins A and B, were tested on 3T3-L1 preadipocytes for differentiation
METHODS
Numerous in vitro and in vivo studies indicate that ellagitannins exhibit anti-inflammatory, anti-atherosclerotic and anti-angiogenic activity which support their potential preventive effect against cardiovascular diseases. Ellagitannins exhibit low bioavailability and are transformed in the
Cardiac fibrosis and inflammation play critical roles in ventricular remodelling after myocardial infarction (MI). Urolithin B (UB), a metabolite of ellagitannin-rich foods, has various biological activities, but its effect on ventricular remodelling after MI has not been determined. The present
Antimelanogenic agents from natural sources have been widely investigated. Urolithin A (UA) and B (UB), the main gut microflora metabolites of dietary ellagic acid derivatives, have various bioactivities such as anti-inflammatory and antiaging effects. In this study, the metabolites were found to
OBJECTIVE
To highlight recent evidence for the ability of polyphenols and their derivatives to reduce muscle wasting in different pathological states.
RESULTS
From January 2016 to August 2017, four articles dealt with the effects of polyphenols on muscle wasting, which were all carried out in mice.
OBJECTIVE
Urolithins are bioactive ellagitannin-derived metabolites showing a wide phenotypic variation in their production by the gut microbiota. This work represents a first in vitro step toward the development of new strategies focused on the oral supplementation of urolithins with the aim of
The intake of polyphenols has been demonstrated to have health-promoting and disease-preventive effects. The pomegranate (Punica granatum L.), which is rich in several polyphenols, has been used for centuries in ancient cultures for its medicinal purposes. The potential health benefits of
Elevation in the levels of reactive oxygen and nitrogen species (RONS), and downregulation of cellular antixoidants, have ubiquitously been reported from studies in animal models of neurodegenerative diseases, including Parkinson's disease (PD) and Alzheimer's disease (AD). Thus, plant-derived
The Keap1/Nrf2/ARE system is a central defensive mechanism against oxidative stress which plays a key role in the pathogenesis and progression of many diseases. Nrf2 is a redox-sensitive transcription factor controlling a variety of downstream antioxidant and cytodefensive genes. Nrf2 has a powerful
Urolithins are intestinal microbial metabolites produced from ellagitannin- and ellagic acid-containing foods such as walnuts, strawberries, and pomegranates. These metabolites, better absorbed than their precursors, can contribute significantly to the beneficial properties attributed to the
Ellagitannin and ellagic acid metabolism to urolithins in the gut shows a large human interindividual variability and this has been associated with differences in the colon microbiota. In the present study we describe the isolation of one urolithin-producing strain from the human faeces of a healthy
