Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Integrative Bioinformatics, Experimental Validation, and Interpretable Machine Learning Reveal Oxyresveratrol‐Mediated Protection Against Cadmium‐Induced Lung Adenocarcinoma‐Related Transcriptional Dysregulation

Environmental Toxicology, EarlyView.
ABSTRACT Cadmium (Cd) is a toxic heavy metal strongly implicated in lung adenocarcinoma (LUAD) through mechanisms involving oxidative stress, epigenetic dysregulation, and chronic inflammation. This study aimed to identify Cd‐responsive genes associated with LUAD and to evaluate the protective effects of oxyresveratrol (O‐RES) against Cd‐induced ...

Novel tyrosinase inhibitory peptide with free radical scavenging ability

Journal 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 ...

Inactivation of Tyrosinase by Dopa

Journal of Investigative Dermatology, 1980
Tyrosinase in a melanosome is known to be inactivated during melanin formation in vivo, and a similar inactivation was observed in vitro when melanosomes isolated from Harding Passey mouse melanoma were incubated with dopa. Tyrosinase, whether particle bound or in soluble form, was inactivated during the dopa-tyrosinase reaction and the reduction rate ...

Plant‐derived nanovesicles as potential drug delivery systems for topical use: Emerging applications in dermatology and cosmetology

VIEW, EarlyView.
Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...

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 ...

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Dorsal Crypsis and Chemical Defense Jointly Shape Brain Size in Toads

Integrative Zoology, EarlyView.
We found that total brain size and dorsal crypsis under both ultraviolet‐sensitive (UVS) and violet‐sensitive (VS) tetrachromatic bird visual models were negatively associated across eight species of toads. Our findings suggest that when species reduce predation risk by evolving increased dorsal crypsis, they may exhibit decreased brain size due to ...
