Identification of Tyrosinase Inhibitors and Their Structure-Activity Relationships via Evolutionary Chemical Binding Similarity and Structure-Based Methods

Molecules, 2021
Tyrosinase is an enzyme that plays a crucial role in the melanogenesis of humans and the browning of food products. Thus, tyrosinase inhibitors that are useful to the cosmetic and food industries are required.

In Vitro and In Vivo Biological Evaluation of Indole-thiazolidine-2,4-dione Derivatives as Tyrosinase Inhibitors

Molecules, 2023
Tyrosinase is an important rate-limiting enzyme in melanin biosynthesis. To find potential tyrosinase inhibitors with anti-melanogenic activity, a series of indole-thiazolidine-2,4-dione derivatives 5a~5z were synthesized by incorporating indole with ...

Comparative Study of High-throughput Screening Models for Anti-hyperpigmentation Compounds

Brazilian Archives of Biology and Technology, 2022
The mushroom tyrosinase assay, B16-F10 mouse melanoma cell model, and zebrafish model are frequently used for high-throughput screening and are widely used for developing anti-hyperpigmentation compounds, although these systems cannot be compared.

Identification of (Z)-2-benzylidene-dihydroimidazothiazolone derivatives as tyrosinase inhibitors: Anti-melanogenic effects and in silico studies

Computational and Structural Biotechnology Journal, 2022
As part of our continuous search for novel tyrosinase inhibitors, we designed 5,6-dihydroimindazo[2,1-b]thiazol-3(2H)-one (DHIT) derivatives based on the structure of MHY773; a potent tyrosinase inhibitor with a 2-iminothiazolidin-4-one template.

In silico and in vitro insights into tyrosinase inhibitors with a 2-thioxooxazoline-4-one template

Computational and Structural Biotechnology Journal, 2021
The β-phenyl-α,β-unsaturated carbonyl (PUSC) scaffold confers tyrosinase inhibitory activity, and in the present study, 16 (Z)-5-(substituted benzylidene)-3-phenyl-2-thioxooxazolidin-4-one analogues containing this scaffold were synthesized.
