Biology of advanced uveal melanoma and next steps for clinical therapeutics [PDF]

open access: yes, 2014
Uveal melanoma is the most common intraocular malignancy although it is a rare subset of all melanomas. Uveal melanoma has distinct biology relative to cutaneous melanoma, with widely divergent patient outcomes.

Tyrosinase Inhibitors from Crude Drugs.

open access: yesBiological and Pharmaceutical Bulletin, 1994
Various crude drugs were examined for their tyrosinase inhibitory activity. Marked activity was observed in Chouji and Yakuchi extracts and the active substances in these extracts were identified as eugenol and yakuchinone A, respectively. Other vanillyl compounds such as ferulic acid, curcumin and yakuchinone B also had higher activities than eugenol ...

UV-A light treatment for controlling enzymatic browning of fresh-cut fruits [PDF]

open access: yes, 2016
Enzymatic browning is critical in the preservation of the quality and the shelf-life of fresh-cut fruits. Non-thermal technologies such as UV radiation are emerging for controlling polyphenol oxidase (PPO) activity, the main agent responsible for ...

A Competitive Inhibitor of Tyrosinase [PDF]

open access: yesAustralian Journal of Biological Sciences, 1951
The kinetics of the activation of catechol by tyrosinase prepared from the potato and the mushroom, and of its inhibition by sodium m-hydroxybenzoate, have been studied. The enzyme-substrate dissociation constants differed markedly between the two enzyme sources (K.

Control Strategies in Guanine Biocrystallization

open access: yesAngewandte Chemie, EarlyView.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Novel tyrosinase inhibitory peptide with free radical scavenging ability

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
Tyrosinase is a key enzyme involved in melanin synthesis. Therefore, various tyrosinase inhibitors have been screened by researchers in recent years. In the present study, we discovered a novel tyrosinase inhibitor, a peptide ECGYF (named EF-5), with ...

Synthesis, In Silico Studies, and Antioxidant and Tyrosinase Inhibitory Potential of 2-(Substituted Phenyl) Thiazolidine-4-Carboxamide Derivatives

open access: yesPharmaceuticals, 2023
Heterocyclic nuclei have shown a wide variety of biological activities, highlighting their importance in drug discovery. Derivatives of 2,4-subsituted thiazolidine have a structural similarity with the substrates of tyrosinase enzymes. Hence, they can be

Loss of strumpellin in the melanocytic lineage impairs the WASH Complex but does not affect coat colour [PDF]

open access: yes, 2016
The five-subunit WASH complex generates actin networks that participate in endocytic trafficking, migration and invasion in various cell types. Loss of one of the two subunits WASH or strumpellin in mice is lethal, but little is known about their role in

Kinetics Investigation on Mushroom Tyrosinase Inhibition of Proso Millet

open access: yesJournal of Chemistry, 2018
Proso millet (Panicum miliaceum) is rich in nutritive components and is widely used as a human food, feed and forage for animals, and fuel. This study investigated the effect of a proso millet extract on the inhibition of tyrosinase, a key enzyme in ...
