An Electrophilic Uridine Building Block for Post‐Synthetic RNA Modification as Exemplified for Spin Labeling

Chemistry – A European Journal, EarlyView.
An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...

Tribochemical Surface Modification of Silicon

Chemistry – A European Journal, EarlyView.
Mechanical scribing activates silicon surfaces by generating reactive sites that spontaneously graft alcohol‐, thiol‐, and alkyne‐terminated molecules under ambient conditions. Within 10 s, high‐coverage, electroactive organic layers form without light, heat, or applied voltage, offering a rapid tribochemical route to functional silicon interfaces for ...

Karrikins Regulate the Redox Balance and Sugar Metabolism of Postharvest Kiwifruit (Actinidia deliciosa)

Plants
Karrikins, a class of butenolide compounds derived from plant-derived smoke, positively regulate plant development and stress tolerance. However, their effects on postharvest fruit have scarcely been reported.

Efficient Light‐Driven Multi‐Electron Accumulation on Viologens by Molecular Control Over Photochemical Reaction Pathways

Chemistry – A European Journal, EarlyView.
Minimum structural changes, maximum output: By either utilizing a more oxidizing Ru(II) polypyridyl chromophore or by using a more reducing SED, the photocatalytic reduction of methyl viologen (MV2+) proceeds via a reductive quenching pathway. This not only significantly accelerates the overall photoreduction process but also allows accumulation of ...

Epigenetic Reprogramming via TET2 Prevents Medial Calcification and Restores Vascular Smooth Muscle Cell Identity

JACC: Basic to Translational Science
Summary: Vascular calcification arises from the osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs) and is a hallmark of many cardiovascular pathologies.

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

EcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Exploring the Anticancer Activity of Ruthenium(II)–Arene and Copper(I) Complexes Bearing N‐Heterocyclic Carbene Ligands Containing Azido, Pyridinium, and Ethisterone‐Derived Triazole Groups

European Journal of Inorganic Chemistry, EarlyView.
A versatile library of backbone‐functionalized N‐heterocyclic carbene (NHC) ligands was developed and efficiently converted into Cu(I) and Ru(II) NHC complexes, demonstrating that ligand functionalization strongly modulates anticancer activity, with Cu(I)–NHC species showing potent and selective antiproliferative effects against ovarian and breast ...
