A tyrosinase inhibitor from Aspergillus niger [PDF]

Journal of Food Science and Technology, 2014
Tyrosinase, in the presence of oxygen, is the main culprit in post harvest browning of food products, resulting in the drop in its commercial value. In an effort to seek natural tyrosinase inhibitors for food applications, a screening programme was undertaken. Of the 26 fungal cultures isolated from soil samples of Agumbe forest, India, one isolate S16,

Thiopurine Drugs Repositioned as Tyrosinase Inhibitors [PDF]

International Journal of Molecular Sciences, 2017
Drug repositioning is the application of the existing drugs to new uses and has the potential to reduce the time and cost required for the typical drug discovery process. In this study, we repositioned thiopurine drugs used for the treatment of acute leukaemia as new tyrosinase inhibitors.

Thiazolopyrimidine derivatives as novel class of small molecule tyrosinase inhibitor. [PDF]

BMC Chem, 2023
Tyrosinase, the rate-limiting enzyme of melanogenesis, plays a crucial role in hyperpigmentation. As a result, in this study, a novel class of thiazolopyrimidine derivatives was developed and synthesized as tyrosinase inhibitor.

Boronic Derivatives of Thiosemicarbazones as Tyrosinase Inhibitors

Pharmaceutics
Background: Tyrosinase is a copper-dependent oxyreductase capable of catalyzing the oxidation of mono- and diphenols. Its activity is crucial in the biosynthetic pathway of melanin, the pigment responsible for the pigmentation of mammalian skin and fur ...

Rifampicin is not an inhibitor of tyrosinase

International Journal of Biological Macromolecules, 2022
Rifampicin has been previously described as an inhibitor of tyrosinase (Chai et al., Int. J. Biol. Macromol. 102 (2017) 425-430). However, rifampicin contains a p-diphenol group and compounds with such a moiety have been shown before to reduce tyrosinase-generated o-quinones.
