Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Rapid Access to Photoswitchable RNA Binders: Fluorination Enhances Protein Rescue by Exon Inclusion

Chemistry – A European Journal, EarlyView.
An adaptable approach, many light‐switchable RNA binders. We report a versatile strategy for rapidly synthesizing photoswitchable RNA binders. The ligands can target SMN2 pre‐mRNA, restoring the levels of the corresponding protein by exon‐inclusion rescue.

Multi‐state Photoswitching in Thienoquinoid‐Based Fluorescent Trithiophenes

Chemistry – A European Journal, EarlyView.
A methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...

Building Blocks for Acetylenic Scaffolding Inspired by 6,6,12‐Graphyne

European Journal of Organic Chemistry, EarlyView.
6,6,12‐Graphyne is an elusive allotrope of carbon. Here, we present the synthesis and properties of a selection of useful molecular building blocks to advance the preparation of various segments of 6,6,12‐graphyne. These modules are derived from tri‐ and tetraethynylethene derivatives, di‐ and tetraethynyl‐substituted tolane derivatives, as well as ...

Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms

Medicinal Research Reviews, EarlyView.
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...
