Effect of Urolithin A on Bone Repair in Mice with Bone Defects
Tissue Engineering and Regenerative Medicine, 2021Bone defect difficult to manage clinically and it is a big challenge to repair it. Secondary metabolites source from herb has shown potential for the treatment of bone defect.Mesenchymal stem cells (MSCs) were isolated from mice and incubated with urolithin A (UA) (10, 25, and 50 µg/mL).

Urolithin A attenuates arsenic-induced gut barrier dysfunction
Archives of Toxicology, 2022Environmental chemicals such as inorganic arsenic (iAs) significantly contribute to redox toxicity in the human body by enhancing oxidative stress. Imbalanced oxidative stress rapidly interferes with gut homeostasis and affects variety of cellular processes such as proliferation, apoptosis, and maintenance of intestinal barrier integrity.

Research progress of ellagitannin intestinal metabolite urolithins
China Journal of Chinese Materia Medica, 2016Ellagitannins is a kind of phenolic compounds with many biological activities. Recent studies have found that the effective ingredients of these compounds have close relationship with their colon-derived bacteria metabolites, that is urolithins.

Synthesis of urolithin derivatives and their anti-inflammatory activity
Biochemical and Biophysical Research CommunicationsTwo series of urolithin derivatives, totally 38 compounds, were synthesized. Their anti-inflammatory activity was investigated by detecting the inhibitory effects on the expression of TNF-α in bone marrow-derived macrophages (BMDMs), showing that 24 of 38 ones reduced the expression of TNF-α.

Appeal of Urolithins from Synthesis to Biological Activities
Journal of Agricultural and Food ChemistryUrolithins (Uros), a series of natural polyphenols derived from ellagic acid through gut bacteria metabolism, have gathered significant attention due to their diverse bioactivities such as maintaining mitochondrial health and anti-inflammatory and antioxidative effects. However, the ability to metabolize Uros varies among individuals.

Colon Cancer Chemopreventive Activities of Pomegranate Ellagitannins and Urolithins
Journal of Agricultural and Food Chemistry, 2010Pomegranate juice derived ellagitannins and their intestinal bacterial metabolites, urolithins, inhibited TCDD-induced CYP1-mediated EROD activity in vitro with IC(50) values ranging from 56.7 microM for urolithin A to 74.8 microM for urolithin C.

Targeting aging with urolithin A in humans
Ageing Research ReviewsUrolithin 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 ...

Neuroprotective Attributes of Gut-derived Urolithins in Parkinson’s Disease
Molecular NeurobiologyUrolithins, a class of gut microbiota-derived metabolites, are produced from dietary ellagitannins and ellagic acid. Their pleiotropic activities, including antioxidant, anti-inflammatory, and mitophagy-enhancing effects, position them as promising candidates for Parkinson's disease (PD), a disorder increasingly understood through the lens of gut-brain

Neuroprotective effects of urolithin a in a mouse model of intracerebral hemorrhage
NeuropharmacologyIntracerebral hemorrhage (ICH) accounts for 10-15 % of all stroke cases and is associated with high mortality and morbidity. Brain injury caused by ICH includes primary and secondary brain injury. Neuroinflammation and apoptosis play important roles in the pathological process of secondary brain injury after ICH.
