Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

open access: yesChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Photochemistry of (‐)‐Levoglucosenone: Norrish Type I Reaction and Photoinduced Electron Transfer Processes

open access: yesChemPhotoChem, Volume 10, Issue 5, May 2026.
Photochemically excited levoglucosenone (LGO) efficiently undergoes Norrish type I reactions yielding particularly functionalized alkenes. In the presence of tertiary amines, this reaction is quenched by an intermolecular electron transfer. This process leads to addition products with high stereoselectivity.

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 13, 1 May 2026.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...

High-pressure activation for the solvent- and catalyst-free syntheses of heterocycles, pharmaceuticals and esters

open access: yesBeilstein Journal of Organic Chemistry
High hydrostatic pressure (HHP) was found to be an efficient activation method in several catalyst- and solvent-free reactions and has found application for the syntheses of heterocycles and the preparation of active pharmaceutical ingredients (APIs) via

Azobenzene‐Functionalized Ionic Liquids: Light‐Responsive Surfactants With Catalytic Potential

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
Surface‐active imidazolium‐based ionic liquids containing an azobenzene group exhibit different micellization properties upon photoisomerization. Applying a sulfonate tag to the azobenzene moiety profoundly affects the physicochemical behavior of both isomers in water.
