Tyrosinase is an enzyme involved in the first steps of the melanogenesis process. It catalyzes the hydroxylation of monophenols to o-diphenols and the oxidation of the latter to o-quinones. Ellagic acid (EA) is a phenolic compound which has been described as a tyrosinase inhibitor and is used in the cosmetic industry as a whitening agent. However, it has hydroxyl groups in ortho position and could...
The development of effective tyrosinase inhibitors has become increasingly important in the cosmetic, medicinal, and agricultural industries for application as antibrowning and depigmenting agents. The kinetic mechanisms of action of tyrosinase on monophenols and o‐diphenols are complex, particularly in the case of monophenols because of the lag period that occurs at the beginning of the reaction...
