Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

Advanced Science, Volume 13, Issue 34, 19 June 2026.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.

Population‐Specific Chemotypes in Pseudomisopates rivas‐martinezii (Sanchez Mata) Güemes From La Serrota and Gredos Massifs (Iberian Central Range)

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Pseudomisopates rivas‐martinezii, a critically endangered Iberian endemic, reveals population‐specific chemotypes when analyzed by elemental analysis, FTIR, and GC–MS. Underground tissues from both populations share a convergent histidine‐derived metabolite profile, whereas aerial parts diverge markedly: La Serrota accumulates phenolic derivatives from

Monoamine Oxidase and Cholinesterase Inhibition Profiles of Semicarbazone and Thiosemicarbazone Derivatives

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Thiosemicarbazones generally show higher MAO‐B inhibitory potential than their corresponding semicarbazones, and particularly T6 is the most potent, which contains R = H and X = S in its Tail Unit, with an IC50 value of 6.45 µM with SI of 3.6. ABSTRACT Twenty semicarbazone and thiosemicarbazone derivatives (T1–T20) were synthesized and evaluated for ...
