Metal–Ligand Cooperative Control of Reactivity in a Porphyrin Manganese(IV)–Oxo–Phenoxyl Radical Complex for Water Activation

ChemistryEurope, Volume 4, Issue 9, September 2026.
We report a manganese porphyrin flanked with an imidazole–phenol pair. Under oxidizing conditions, we generate a manganese(IV)‐oxo and a spatially separated phenoxyl radical. We found that the Mn(IV)═O–PhO• can be the siege for the water oxidation. The Oxygen Evolving Complex (OEC) is a Mn4Ca cluster at the heart of Photosystem II that catalyzes the ...

Evaluation of Novel Isatin–Schiff Base Derivatives: Monoamine Oxidase Inhibition and Antimicrobial Assessment

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Five novel series of isatin–Schiff base derivatives are synthesized and evaluated for neuroprotective and anti‐infective potential. The compounds demonstrate exceptional, reversible, and competitive monoamine oxidase inhibition, with chloro‐substitutions dictating isoform selectivity.

Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes

Chemistry – A European Journal, Volume 32, Issue 32, 24 August 2026.
The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...
