Description
Summary:Synopsis This paper forms part of studies searching for new bioactive ingredients for cosmetics, for example, in the whitening agent field. The aim of our work was to present resveratrol as an original substrate for tyrosinase with very promising cosmetic perspectives. This study was based on several spectrophotometric analyses with minor adaptations. These analyses suggested that resveratrol is biotransformed by tyrosinase into an oxydated form, becoming a powerful inhibitor of tyrosinase. Furthermore, we show that resveratrol can be used as an additive compound in whitening cosmetics, particularly with a Morus alba extract. These results may help in understanding tyrosinase active site structure and mechanism. Résumé Cet article fait partie d’un vaste projet de recherche de biomolécules actives originales à visée cosmétique. Les agents dépigmentants en sont un exemple. Dans ce cadre, nous présentons le resvératrol comme substrat original de la tyrosinase avec des applications cosmétiques intéressantes. Cette étude est basée sur diverses expériences spectrophotométriques. Les analyses montrent d’une part que le resvératrol agit comme substrat de la tyrosinase. D’autre part, le produit biotransformé semble inhiber l’activité tyrosinase. Une application directe consiste à combiner le resvératrol avec d’autres agents dépigmentants de façon à atteindre un effet synergique entre les deux actifs.
