Core Tip

Core tip: Urolithin A (UA) - an ellagitannin metabolite generated by the intestinal bacteria at physiologically relevant micromolar concentrations, offers gastrointestinal (GI) protection. The health benefit is principally related to anticancer and anti-inflammatory effects. UA can regulate multiple tumor and inflammatory signaling pathways and enzyme activities, including those involved in carcinogen biotransformation and antioxidant defense. The presented herein data support the potential of both pure compound and in vivo generated UA in treatment interventions against GI ailments.
