Urolithin B: Two-way attack on IAPP proteotoxicity with implications for diabetes

Frontiers in Endocrinology, 2022
IntroductionDiabetes is one of the major metabolic diseases worldwide. Despite being a complex systemic pathology, the aggregation and deposition of Islet Amyloid Polypeptide (IAPP), or amylin, is a recognized histopathological marker of the disease ...

In Silico and In Vitro Study of Antioxidant Potential of Urolithins

Antioxidants, 2023
In this work, quantum chemical calculations based on density functional theory (DFT) were performed to predict the antioxidant potential of four bioactive gut microbiota metabolites of the natural polyphenols ellagitannins (ETs) and ellagic acid (EA), also known as urolithins (UROs). In order to evaluate their ability to counter the effect of oxidative

Muscadine or amla extracts standardized to ellagic acid content ameliorate glucolipotoxicity associated β-cell dysfunction via inhibition of IL-1β and improved insulin secretion

Food Production, Processing and Nutrition, 2020
Glucolipotocixity induces IL-1 β secretion which impairs pancreatic β-cell insulin secretion. Ellagic acid and urolithin A have strong anti-inflammatory effect on cells. Muscadine and amla are very good sources of ellagic acid. The present study examined

Urolithins: Diet-Derived Bioavailable Metabolites to Tackle Diabetes [PDF]

Nutrients, 2021
Diabetes remains one of the leading causes of deaths and co-morbidities in the world, with tremendous human, social and economic costs. Therefore, despite therapeutics and technological advancements, improved strategies to tackle diabetes management are still needed. One of the suggested strategies is the consumption of (poly)phenols. Positive outcomes

Urolithin A in Health and Diseases: Prospects for Parkinson’s Disease Management

Antioxidants, 2023
Parkinson’s disease (PD) is a chronic and progressive neurodegenerative disorder characterized by a complex pathophysiology and a range of symptoms. The prevalence increases with age, putting the ageing population at risk. Disease management includes the improvement of symptoms, the comfort of the patient’s life, and palliative care.
