Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

open access: yesChemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2673-2691, May 2026.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Development of Mild Palladium‐Catalyzed N‐Arylation of Ortho‐Acylanilines in Rhamnolipid Micellar System

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Aqueous micellar catalysis using industrially sourced rhamnolipids enables efficient Pd‐catalyzed N‐arylation of o‐acylanilines at 40°C. This surfactant‐driven system offers a sustainable and more efficient alternative to organic solvents, combining broad substrate scope, low catalyst loading, and enhanced energy efficiency.

The Role of Acridin-9(10H)-one in the Inhibition of Carbon Steel Corrosion: Thermodynamic, Electrochemical and DFT Studies

open access: yesInternational Journal of Electrochemical Science, 2013
Inhibition of the corrosion of carbon steel in aerated 1.0 M HCl solution by acridin-9(10H)-one (Hydacr) was investigated by use of gravimetric, potentiodynamic polarization (Tafel) and electrochemical impedance spectroscopy.

Shaping the Afterglow of Indolo[3, 2‐b]Carbazoles via Modulating Intersystem Crossing (ISC/rISC) and Phosphorescence Rates

open access: yesAggregate, Volume 7, Issue 4, April 2026.
In a series of indolo[3,2‐b]carbazoles (X‐ICZ‐p1; X = F, Cl, Br), the afterglow properties are shaped by modulating intersystem crossing (ISC/rISC) and phosphorescence rates. F/Cl‐ICZ‐p1 systems show moderate rates, achieving color‐tunable, dual‐mode afterglow in polymethyl methacrylate from persistent thermally activated delayed fluorescence (pTADF ...
