Urolithin E is a secondary metabolite produced by the gut microbiota from ellagitannins and ellagic acid. As a member of the urolithin family, it features a polyhydroxylated dibenzopyran-6-one skeleton. Research indicates that Urolithin E possesses significant antioxidant and anti-inflammatory activities, capable of scavenging free radicals and inhibiting oxidative stress-induced cellular damage. Furthermore, as a bioactive metabolite, it has demonstrated potential biological functions in modulating apoptosis and inhibiting the proliferation of specific cancer cell lines.
