Tyrosinase inhibitors as potential antibacterial agents

open access: yes, 2019
Tyrosinase is a copper-containing enzyme that catalyzes the biosynthesis of melanin. This enzyme is present in bacteria, fungi, plants and animals, and plays multiple roles in pigmentation, wound healing, radiation protection, primary immune responses ...

Therapeutic Reversal of Severe Neuropsychiatric Symptoms in Wilson's Disease: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 11, November 2026.
ABSTRACT Wilsons disease is an autosomal recessive genetic disorder of copper metabolism that results in copper accumulation in liver and other organs. Hepatic manifestation tends to occur earlier than the neurological manifestation. We present a case with psychiatric presentation.

Beyond monofunctionality: structural perspectives on phenol oxidase side activity in a catalase

open access: yesActa Crystallographica Section D, Volume 82, Issue 11, Page 1224-1239, November 2026.
Structural and biochemical characterization of the extracellular fungal catalase ClCPO uncovers an unexpected phenol oxidase promiscuity. Crystal structures, substrate docking and electron‐transfer pathway analysis identify ligand‐binding regions and support a working mechanistic model for catalase‐associated phenol oxidase activity.Catalases are ...

Nuclear Functional Divergence and Genetic Basis of Cap Colour Variation Revealed by T2T Genomes of Two Compatible Monokaryons in Pholiota adiposa

open access: yesMicrobial Biotechnology, Volume 19, Issue 11, November 2026.
T2T genomes of two compatible monokaryons reveal nuclear functional specialization and identify two candidate loci on chromosomes 6 and 12 associated with red cap colour in the edible mushroom Pholiota adiposa. ABSTRACT Basidiomycete fungi maintain a dikaryotic state throughout their life cycle, in which two genetically distinct haploid nuclei coexist ...

Transformative Chemie maskierter Ortho‐Chinone: Über die direkte Aktivierung von Guajacol zu Lignin‐basierten Klebstoffen

open access: yesAngewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Erneuerbare Guajacole werden durch Phenyliodid(III)diacetat rasch zu maskierten ortho‐Chinonen oxidiert und bilden eine neue Monomerklasse, die mit Multithiolen selektive Michael‐Typ‐Polyadditionen zu Polymeren mit Thiol‐Guajacol‐Verknüpfungen eingeht.

Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 43, 19 October 2026.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

open access: yesAdvanced Science, Volume 13, Issue 59, 23 October 2026.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

The inhibitory effects of ethanol extracts from fresh grape and grape cell on mushroom tyrosinase activity

open access: yes, 2009
[[abstract]]In living organisms, melanin can be formed by enzymatic reaction of tyrosinase with certain substrates such as L-3,4-dihydroxyphenylalanine (L-dopa). The objective of this study was to determine the inhibitory effects of seed and peel ethanol
