Visible‐Light Photocatalyzed Selective Synthesis of 1,2‐ or 1,3‐Dithianes From Thietanes: An Experimental and Theoretical Study

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 24, December 22, 2025.
Although this article formally presents a regioselective photochemical ring enlargement of thietanes into 1,2‐ or 1,3‐dithianes, time‐dependent density functional theory calculations have revealed that 1,3‐dithianes are in fact formed thought photoinduced hydrogen atom transfers from 1,2‐dithianes initially resulting from the ring enlargement using ...

A Miniaturized Optical Bioassay Towards Early‐Stage Diagnosis of Cancer Using Immunosensing of Biomarkers (CA 15.3, PSA and CEA) by Toluidine Blue‐Decorated Poly(Methyl Methacrylate): Proof of Concept

open access: yesAnalytical Science Advances, Volume 6, Issue 2, December 2025.
ABSTRACT The current study evaluated the application of a novel and advanced photochemical biosensing platform for the detection of multiple biomarkers of prostate‐specific antigen (PSA), carcinoembryonic antigen (CEA) and cancer antigen 15–3 (CA 15.3) in human plasma samples using optical biomedical analysis.

High‐Throughput Photocatalysis for Generating Reliable Datasets Analyzed by Machine Learning

open access: yesChemPhysChem, Volume 26, Issue 23, November 28, 2025.
Photocatalytic materials are typically tested on limited analytes, limiting real‐world relevance. High throughput‐photocatalysis, enabling rapid, modular experimentation across 27 analytes is introduced. Using P25 TiO2, dye removal datasets with machine learning is paired.

In‐Silico Exploration of the StreptomeDB Database for Potential Irreversible DprE1 Inhibitors toward Antitubercular Treatment

open access: yesChemistryOpen, Volume 14, Issue 11, November 2025.
StreptomeDB‐derived nitro compounds are screened against Mycobacterium tuberculosis decaprenylphosphoryl‐D‐riboseoxidase (DprE1) . Covalent docking, molecular dynamics simulations, and molecularmechanics/generalized Born surface area analyses identify hydroxythaxtomin and lajollamycin B as potent DprE1 inhibitors, surpassing the reference PBTZ169 in ...

Small Molecular Dibenzochalcogenophenes as Potent Organic Emitters

open access: yesChemistry – A European Journal, Volume 31, Issue 56, October 8, 2025.
This review compiles recent achievements and applications of purely organic small luminescent DBC. We present frequently employed functionalities and design strategies, accomplishing room temperature phosphorescence (RTP). In addition, we discuss the challenges for luminescent selenium and tellurium derivatives as well as the influence of commercial ...
