TYROSINASE AND PLANT RESPIRATION [PDF]

Journal of General Physiology, 1943
The evidence presented in this paper supports the conclusion that at least 85 per cent of the oxygen uptake of the respiring tissue of potato tuber enters the chemistry of the cell by way of a tyrosinase-catalyzed oxidation. The qualitative aspects of this conclusion are in agreement with the claim made by Boswell and Whiting.

Tyrosinase-Mediated Oxidative Coupling of Tyrosine Tags on Peptides and Proteins

, 2020
Oxidative coupling (OC) through o-quinone intermediates has been established as an efficient and site-selective way to modify protein N-termini and the unnatural amino acid p-aminophenylalanine (paF).

Synthesis and Biological Activity Evaluation of 2-Cyanopyrrole Derivatives as Potential Tyrosinase Inhibitors

Frontiers in Chemistry, 2022
In order to find potential inhibitors of tyrosinase, two series of pyrrole derivatives A (1–17) and B (1–8) were synthesized and screened for their inhibitory activities on tyrosinase. Most of the 2-cyanopyrrole derivatives exhibited effective inhibitory

Tyrosinase Driven‐Intracellular Polymerization of a Porphyrin Derivative Induced Immunogenic Death of Melanoma Cells and Strengthened Photodynamic Therapy

Advanced Science, EarlyView.
This study uses tyrosinase, which is highly expressed in melanoma, to drive porphyrins to polymerize and self‐assemble within tumor cells to form retented microstructures. This process induces immunogenic death and activates immune responses (M1 macrophages, dendritic cells, CD8+T cells), turning “cold” tumors into “hot” tumors.

The inhibition of tyrosinase by pyridinones [PDF]

Biochemical Journal, 1989
3-Hydroxypyridine-4-ones have potential as orally active chelators of iron(III) and therefore may find application in the treatment of thalassaemia. An undesirable feature of these molecules is that they inhibit tyrosinase. We have established that alkyl substitution at position 2 in the aromatic ring minimizes interaction with tyrosinase and does so ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common
