Design, Synthesis, and Biological Evaluation of Benzimidazol‐2‐One Hybrids as Potential Anti‐Alzheimer's Disease Agents

open access: yesDrug Development Research, Volume 87, Issue 6, September 2026.
ABSTRACT Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder for which single‐target therapies often provide insufficient benefit, motivating the development of multi‐target‐directed ligands (MTDLs). In this study, a novel series of benzimidazolone‐based hybrids incorporating piperazine, coumarin, and triazole moieties was designed,

Unleashing the power of visible‐near infrared spectroscopy: predicting Golden Delicious apple enzyme activity

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7503-7511, September 2026.
Abstract BACKGROUND Enzymatic browning is a significant reaction in fruits that affects their color, appearance, and quality. The quality of apples, as a perishable product, is mainly influenced by the activity of two browning‐related enzymes, polyphenol oxidase (PPO) and peroxidase (POD), during storage.

Crosslinking of Linear Polyimines Into Aminal‐Linked Porous Organic Polymers for C2 Hydrocarbon/Methane Separation

open access: yesAngewandte Chemie, Volume 138, Issue 35, 24 August 2026.
Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...

Glove Reuse Limits in Hair Dyeing: Permeation of p‐Phenylenediamine and Aminophenols Through Natural Rubber Latex and Neoprene After Repeated Washing

open access: yesContact Dermatitis, Volume 95, Issue 3, Page 309-317, September 2026.
Disposable glove reuse reduced chemical protection during repeated hair‐dye exposure. Under ASTM F739 testing, natural‐rubber‐latex deteriorated rapidly after one reuse, whereas neoprene performed better initially but also declined over repeated cycles. Wash type had no significant effect. These findings support single‐use only and discourage the reuse
