Phenol oxidation by mushroom waste extracts: a kinetic and thermodynamic study
(2013)
Tyrosinase activity of mushroom extracts was checked for their ability to degrade phenol. Phenol oxidation kinetics was investigated varying temperature from 10 to 60 C and the initial values of pH, enzyme activity and ...
Inactivation of tyrosinase photoinduced by pterin
(Academic Press Inc Elsevier Science, 2012-08)
Tyrosinase catalyzes in mammals the first and rate-limiting step in the biosynthesis of the melanin, the main pigment of the skin. Pterins, heterocyclic compounds able to photoinduce oxidation of DNA and its components, ...
Comparative Study of Glyceryl Behenate or Polyoxyethylene 40 Stearate-Based Lipid Carriers for Trans-Resveratrol Delivery: Development, Characterization and Evaluation of the In Vitro Tyrosinase Inhibition
(2018-04-01)
Trans-resveratrol (RSV) is a natural compound with several properties, such as the ability to inhibit the tyrosinase enzyme, with potential application as a skin-lightning agent and for the treatment of skin disorders ...
Prenylated Flavanones with Anti-tyrosinase Activity from Dalea boliviana
(American Chemical Society, 2011-01)
Three new prenylated flavanones, (2S)-5,7,2′-trihydroxy-5′-(1′′′,1′′′-dimethylallyl)-8-prenylflavanone (1), (2S)-5,7,2′-trihydroxy-8,3′-diprenylflavanone (2), and (2S)-5,2′-dihydroxy-6′′,6′′-dimethylchromeno-(7,8:2′′,3′′ ...
Effects of Coccoloba uvifera L. on UV-stimulated melanocytes
(Wiley-Blackwell, 2008-12-01)
Exposure to ultraviolet (UV) radiation induces generation of reactive oxygen species, production of proinflammatory cytokines and melanocyte-stimulating hormone (MSH) as well as increase in tyrosinase activity. The potential ...

(Wiley-Blackwell, 2008-12-01)
Exposure to ultraviolet (UV) radiation induces generation of reactive oxygen species, production of proinflammatory cytokines and melanocyte-stimulating hormone (MSH) as well as increase in tyrosinase activity. The potential ...
Lipid-matrix effects on tyrosinase immobilization in Langmuir and Langmuir-Blodgett films
(2021-01-01)
The immobilization of the enzyme tyrosinase (Tyr) in lipid matrices can be explored to produce biosensors for detecting polyphenols, which is relevant for the food industry. Herein, we shall demonstrate the importance of ...
Inhibitory effects of compounds isolated from Lepechinia meyenii on tyrosinase
(Pergamon-Elsevier Science Ltd, 2019-03)
To contribute enzymatic browning inhibitors to the food industry and also extend knowledge about the phytochemical profile of the anti-tyrosinase plant Lepechinia meyenii, its ethanol extract was subjected to bioguided ...
A Tyrosinase Inhibitor from a Nitrogen-Enriched Chemically Engineered Extract
(American Chemical Society, 2019-09)
The enzyme tyrosinase is involved in the biosynthesis of melanin and the enzymatic browning of fruits and vegetables, and therefore, its inhibitors have potential to treat hyperpigmentary disorders or to function as food ...
In vitro biological evaluation and molecular docking studies of natural and semisynthetic flavones from Gardenia oudiepe (Rubiaceae) as tyrosinase inhibitors
(Academic Press Inc Elsevier Science, 2019-02)
Hyperpigmentation disorders are difficult to treat without causing permanent depigmentation or irritation. The most effective hypopigmenting agents are tyrosinase inhibitors, however some of those currently used have shown ...
