Analysis of Benzoate 1,2‐Dioxygenase Identifies Shared Electron Transfer Components With DxnA1A2 in Rhizorhabdus wittichii RW1

open access: yesJournal of Basic Microbiology, Volume 65, Issue 8, August 2025.
ABSTRACT Rhizorhabdus wittichii RW1 is known for its ability to degrade polycyclic aromatic hydrocarbons, such as dibenzo‐p‐dioxin (DD) and dibenzofuran (DF). We hypothesized that the R. wittichii RW1 benzoate 1,2‐dioxygenase shares electron transfer components with the DD/DF angular dioxygenase (DxnA1A2), similar to many aromatic hydrocarbon degrading

Recent advances in the structure, function and regulation of the volume‐regulated anion channels and their role in immunity

open access: yesThe Journal of Physiology, Volume 603, Issue 15, Page 4255-4291, 1 August 2025.
Abstract figure legend The volume‐regulated anion channel (VRAC), composed of leucine‐rich repeat‐containing 8 (LRRC8) proteins, serves both canonical and non‐canonical functions in vertebrate cells. The canonical function of this channel relates to its original description, which is homeostatic regulation of cell volume in response to hypotonic ...

Tuning NIR Absorption and Emission of Diphenyl‐Dihydrophenazine‐Based Merocyanines with Ultra Narrow Band Gap

open access: yesChemistry – A European Journal, Volume 31, Issue 42, July 25, 2025.
Novel merocyanine derivatives with a strong diphenyl‐dihydrophenazine donor and a series of strong electron acceptors were developed. The indanone and indandione acceptor units were modified by dicyanovinylene groups to tune acceptor strength. Among these derivatives, DPPZ‐IDD realized an ultranarrow electrochemical gap of 0.93 eV and an optical band ...

Hochgradig enantioselektive Organokatalyse mit zweizähnigen Halogenbrückendonoren

open access: yesAngewandte Chemie, Volume 137, Issue 30, July 21, 2025.
In einer Mukaiyama‐Aldol‐Modellreaktion mit allgemeinen Substraten wurden hohe Enantioselektivitäten mit einem modifizierbaren, bidentaten Iod(I)‐basierten Halogenbrücken‐Organokatalysator erreicht. Die entscheidende Rolle der Halogenbrücken wurde durch das schlechte Abschneiden des entsprechenden Wasserstoffbrückendonors und durch DFT‐Berechnungen ...

Highly Enantioselective Organocatalysis with Bidentate Halogen Bond Donors

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 30, July 21, 2025.
In a model Mukaiyama aldol reaction with unbiased substrates, high enantioselectivity was achieved with a modifiable bidentate iodine(I)‐based halogen bonding organocatalyst. The crucial role of halogen bonding was confirmed by the low performance of the corresponding hydrogen bond donor and via DFT calculations.

A General Strategy for C(sp3)─H Bond Etherification via Quinoline Derivative‐Mediated Electrolysis

open access: yesAdvanced Science, Volume 12, Issue 22, June 12, 2025.
A quinoline‐based mediator is introduced for the electrochemical etherification of C(sp3)─H bonds, enabling the process with minimal dependence on substrate electronic properties. The reaction demonstrates compatibility with various C─H bonds, including tertiary benzylic C─H bonds and unactivated C(sp3)─H bonds.

PTC in the Polyenolate‐Mediated [10+2]‐Cycloaddition for the Synthesis of α,α‐Disubstituted Amino Acid Precursors

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 8, April 15, 2025.
Abstract The manuscript describes a formal [10+2] higher‐order cycloaddition between 2‐arylideneindan‐1‐ones and α‐alkylidene azlactones as higherene precursors and higherenofiles respectively. The reaction is realized under Brønsted‐base catalysis utilizing the phase transfer catalysis approach.

Panchromatic Absorption of Unsymmetrical Donor‐Acceptor Dyes Based on a Meta‐Conjugated 1,3,5‐Heteroaryltriazine Core

open access: yesChemistry – A European Journal, Volume 31, Issue 11, February 20, 2025.
Little explored are 1,3,5‐triazine cores that are substituted with three different heteroaromatic groups despite their distinct optical and electronic properties. 1,3,5‐Triazines substituted with strong donor and acceptor thiophenes give rise to long wavelength absorption tails due to intramolecular charge transfer absorptions of the meta‐conjugated ...
