Urolithin and Reduced Urolithin Derivatives as Potent Inhibitors of Tyrosinase and Melanogenesis: Importance of the 4-Substituted Resorcinol Moiety [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
We previously reported (E)-β-phenyl-α,β-unsaturated carbonyl scaffold ((E)-PUSC) played an important role in showing high tyrosinase inhibitory activity and that derivatives with a 4-substituted resorcinol moiety as the β-phenyl group of the scaffold resulted in the greatest tyrosinase inhibitory activity.

Urolithin A, C, and D, but not iso‐urolithin A and urolithin B, attenuate triglyceride accumulation in human cultures of adipocytes and hepatocytes

open access: yesMolecular Nutrition & Food Research, 2016
ScopeUrolithins (Uro) are ellagic acid (EA)‐derived metabolites produced by gut microbes. There is a growing interest in the biological activities of Uro. Our aim was to evaluate the impacts of Uro on regulating triglyceride (TG) accumulation using cultures of primary human adipocytes and hepatoma Huh7 cells.Methods and resultsUroA, UroB, UroC, UroD ...
