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 ...

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.

Targeting aging with urolithin A in humans: A systematic review

Ageing Research Reviews
Urolithin A (UA) is a gut metabolite derived from ellagic acid. This systematic review assesses the potential geroprotective effect of UA in humans. In five studies including 250 healthy individuals, UA (10-1000 mg/day) for a duration ranging from 28 days to 4 months, showed a dose-dependent anti-inflammatory effect and upregulated some mitochondrial ...

Fermentative Liberation and Transformation of Bioactive Compounds: Ellagic Acid from Nut Press Cake Ellagitannins

Applied Sciences
Oil extracted from walnuts leaves behind large amounts of defatted press cake that still retains valuable nutrients. Solid state fermentation (SSF) is a promising method to liberate bioactive compounds from food by-products.
