Tyrosinase Inhibition and Antimelanogenic Effects of Resorcinol‐Containing Compounds
ChemMedChem, Volume 19, Issue 23, December 2, 2024.Resorcinol‐based compounds stand out as key inhibitors of tyrosinases (TYR) owing to their phenolic group's interaction with the dicopper centre and their ability to resist TYR‐mediated oxidation. While some well‐known examples are employed in dermatocosmetics and skin‐whitening products, this review covers the broader diversity of scaffolds, including
