Synthesis, Characterization and AntibacterialActivity of Azomethine Derivatives Derived from 2-Formylphenoxyacetic Acid

Molecules, 2007
A series of eight new azomethine derivatives were synthesized by reacting 2-formylphenoxyacetic acid with aromatic amines. The chemical structures of these compounds were confirmed by means of 1H-NMR, 13C-NMR, MS and elemental analysis.

Second-generation nitazoxanide derivatives: thiazolides are effective inhibitors of the influenza A virus [PDF]

, 2018
Aim: The only small molecule drugs currently available for treatment of influenza A virus (IAV) are M2 ion channel blockers and sialidase inhibitors. The prototype thiazolide, nitazoxanide, has successfully completed Phase III clinical trials against ...

Recent advances in organic broad‐spectrum photodetection materials and devices

InfoMat, EarlyView.
Graphical Abstract This review systematically outlines the evolution of organic photodetectors from fullerene‐based to advanced non‐fullerene acceptors, highlighting how molecular engineering (e.g., D–A, quinoidal, and A‐D‐A′‐D‐A architectures) extends spectral response into the short‐wave infrared region.

An Organometallic [2]Catenane With Pt‒(di‐NHC)‒Pt Units: A Topology‐Driven Strategy for Enhanced Phosphorescence in Discrete Aggregates

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
The mechanically interlocked Borromean rings are stabilized by π···π stacking interactions while the [2]catenane is stabilized by solvophobic effects. While the π···π interactions in the Borromean rings lead to severe luminescence quenching, the solvophobically assembled [2]catenane effectively circumvents these interactions, simultaneously restricting

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Isolation and Structural Characterization of Se‐Hügerschoff Intermediates Derived From 4‐Bromoaniline

Journal of Heterocyclic Chemistry, EarlyView.
Isolation and characterization of Se‐brominated Hügerschoff intermediates enable structural and mechanistic insight into seleno‐Hügerschoff cyclization to 2‐aminobenzoselenazoles. ABSTRACT A brominated intermediate within the Hügerschoff reaction has long been postulated but never directly observed.
