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

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Evaluating Thiram‐Induced Embryotoxicity Using Integrated In Silico, In Vitro, and Transcriptomic Approaches

Environmental Toxicology, EarlyView.
ABSTRACT Long‐term exposure to low‐dose food contact materials (FCMs) has raised concerns regarding developmental toxicity. In the present study, we prioritized FCMs with potential developmental toxicity using a weight‐of‐evidence computational model, which predicted 127 chemicals to be of high concern.
