Upregulation of Melanogenesis and Tyrosinase Activity: Potential Agents for Vitiligo

Molecules, 2017
Melanin, the compound primarily responsible in humans for hair, eye and skin pigmentation, is produced by melanocytes through a complicated process called melanogenesis that is catalyzed by tyrosinase and other tyrosinase-related proteins.

Investigation of the Efficacy of Benzylidene-3-methyl-2-thioxothiazolidin-4-one Analogs with Antioxidant Activities on the Inhibition of Mushroom and Mammal Tyrosinases

Molecules
Based on the fact that substances with a β-phenyl-α,β-unsaturated carbonyl (PUSC) motif confer strong tyrosinase inhibitory activity, benzylidene-3-methyl-2-thioxothiazolidin-4-one (BMTTZD) analogs 1–8 were prepared as potential tyrosinase inhibitors ...

Valorization of fruit pits from Prunus laurocerasus and Prunus cerasifera as agro‐food byproducts: Bioactive properties and safety assessment for potential food additive applications

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Food additives are widely used to extend the shelf life of foods and maintain their quality. In this study, the potential of Prunus laurocerasus and Prunus cerasifera fruit pits (endocarp and seed) as food additives was investigated in terms of cytotoxicity, antigenotoxicity, antioxidant activity, enzymatic anti‐browning, and urease

The Mycobacterium tuberculosis Rv0132c Gene Product Mtb‐FGD2 Can Act as an F420‐Dependent Glucose Dehydrogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The role of the cell envelope‐associated Rv0132c/FGD2 from Mycobacterium tuberculosis has long been a subject of debate. Importantly, FGD2 is found only in pathogenic mycobacteria, making it a potential drug target. While some suggest it functions as a glucose‐6‐phosphate dehydrogenase, others propose it acts instead as an F420‐dependent ...
