Anti‐Apoptotic and Neurite‐Protective Nanomedicine Augments Embryonic Stem Cells‐Derived Retinal Ganglion Cell Transplantation in Glaucoma Recovery

Advanced Science, EarlyView.
Lithium‐epigallocatechin gallate nanoparticles (Li‐EGCG NPs) are co‐transplanted with embryonic stem cell‐derived retinal ganglion cells (ESC‐RGCs) to enhance cell survival and therapeutic efficacy in an acute pathological glaucomatous injury model. This synergistic approach protects RGC cells, preserves retinal structure and improves visual function ...

Reactions of nitroxides XIII: Synthesis of the Morita–Baylis–Hillman adducts bearing a nitroxyl moiety using 4-acryloyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl as a starting compound, and DABCO and quinuclidine as catalysts

Beilstein Journal of Organic Chemistry, 2012
The Morita–Baylis–Hillman adducts bearing a nitroxyl moiety were synthesized from 4-acryloyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl and aliphatic, aryl and heterocyclic aldehydes.

A Computational Journey across Nitroxide Radicals: From Structure to Spectroscopic Properties and Beyond

Molecules, 2021
Nitroxide radicals are characterized by a long-lived open-shell electronic ground state and are strongly sensitive to the chemical environment, thus representing ideal spin probes and spin labels for paramagnetic biomolecules and materials.

A Polymer‐Intercalated Modulation Assembly Strategy Towards Mesoporous Single‐Crystalline BiVO4 Materials for Enhanced Photocatalytic Performance

Advanced Science, EarlyView.
A polymer‐intercalated modulation assembly strategy was proposed to synthesize mesoporous single‐crystalline BiVO4 with tunable pore structure by co‐assembly of inorganic–organic composite through coordination bonds and hydrogen bonds. Thanks to single‐crystalline properties and mesoporous structure with vanadium vacancy microenvironment, the prepared ...

Residue‐Specific Signatures of Structural Water Identified by Dissolution Dynamic Nuclear Polarization with UV‐Generated Radicals

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Structural water molecules in proteins are notoriously hard to detect in solution. Hyperpolarized water with UV radicals as polarizing agents provides the sensitivity and resolution to detect residue‐specific signatures of structural water with NMR spectroscopy.

Spatial structure regulation towards armor-clad five-membered pyrroline nitroxides catholyte for long-life aqueous organic redox flow batteries

eScience
Five-membered pyrroline nitroxides with high-potential is fascinating as catholyte for aqueous organic redox flow batteries (AORFBs), however, it suffers from a primary deficiency of insufficient stability due to ring-opening side reaction.

Aufklärung des Wirkmechanismus der Synthetase: Das Dimer der Pyrrolysyl‐tRNA‐Synthetase nutzt sekundäre Bindungsstellen in der Zelle

Angewandte Chemie, EarlyView.
Das Dimer der Pyrrolysyl‐tRNA‐Synthetase zeigt im katalytischen Zyklus einen alternierenden Wirkmodus seiner Monomere, der durch die Belegung sekundärer Bindungsstellen an den Intermonomer‐Grenzflächen außerhalb der katalytischen Bindungsstelle realisiert wird.

Simultaneous Imaging of Cu+ and Cu2+ in Neural Cells Using DNAzyme Probes Reveals Mechanistic Link Between Copper Redox Imbalance and Amyloid Pathology

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
We develop Cu+‐ and Cu2+‐specific DNAzyme fluorescent probes to visualize both copper redox states in living neurons. Aβ oligomers cause intracellular copper overload, triggering FDX1 dependent cuproptosis and generating ROS. This work links copper redox imbalance with Aβ pathology and offers a selective, sensitive way to monitor copper homeostasis in ...
