Urolithin A, a Diet‐Derived Gut Microbial Metabolite Against Pulmonary Hypertension Identified via Molecular Docking, Molecular Dynamics and Surface Plasmon Resonance

Food Safety and Health, Volume 4, Issue 3, Page 721-736, July 2026.
Urolithin A, a gut microbial metabolite, binds TNF to suppress proliferation, inflammation, and oxidative stress, offering a promising microbe‐derived therapeutic avenue for pulmonary hypertension. ABSTRACT Pulmonary hypertension (PH) is a complex and multifactorial disease that poses a significant clinical challenge.

Urolithin 9-dehydroxylase from Enterocloster bolteae JCM 12243T catalyzing regiospecific dehydroxylation of urolithins

Enzyme and Microbial Technology
Urolithins are metabolites derived from ellagic acid, a compound that is present in many plants, including pomegranate, via the action of gut microorganisms. Among them, urolithin A exhibits antioxidant and anti-inflammatory activity and promotes autophagy, making it a potential contributor to human health.

Ellagitannins (Ellagic Acid, Urolithin A, Urolithin B) Inhibit the Catalytic Activity of Human Recombinant Metalloproteinase 9

Iranian Journal of Pharmaceutical Research
Background: Ellagitannins are well-recognized for their antioxidant, chemopreventive, anti-inflammatory, and neuroprotective efficacy. Due to their poor absorption and extensive catabolism, it is proposed that urolithins, as ellagic acid (EA) metabolites, are the real active molecules exerting these biological functions.

Correlation between intestinal microbiota and urolithin metabolism in a human walnut dietary intervention

BMC Microbiology
This study is to investigate the relationship between the intestinal microbiota and urine levels of the ellagic acid-derived polyphenols, the urolithins, in a cohort of subjects following a three-week walnut dietary intervention.

Microbiota-derived urolithin A in monoclonal gammopathies and multiple myeloma therapy

Microbiome
Background Gut microbiota-derived urolithins may influence multiple myeloma (MM) disease progression and treatment. We analyzed urolithins and their associated microbiota in a retrospective cohort of 45 patients with active MM or premalignant disease ...

Enhancement of the gut barrier integrity by a microbial metabolite through the Nrf2 pathway

Nature Communications, 2019
Urolithins are microbial metabolites derived from food polyphenols. Here, Singh et al. show that urolithin A and a synthetic analogue enhance gut barrier function via Nrf2-dependent pathways and mitigate inflammation and colitis in mice, highlighting a ...

Synthesis of urolithin A 3- and 8-glucuronides via intramolecular biaryl coupling

Results in Chemistry
Urolithins, 6H-dibenzo[b,d]pyran-6-one derivatives, are metabolites produced by gut microbiota from ellagic acid, a natural antioxidant. They are more efficiently absorbed than ellagic acid and contribute to the health benefits of ellagitannin-rich foods.
