Toward Multi(radio)metalated DNA: Enzymatic Polymerization of Metal‐Chelate‐Modified Deoxyribonucleoside Triphosphates

open access: yesAngewandte Chemie, EarlyView.
This work presents the first enzymatic polymerization of defined metal‐chelator‐modified nucleotides that leverage polymerase fidelity for uniform (radio)metal loading with successful incorporation of five different metals: Ga, In, Tb, Lu, and Y.

Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Citrus aurantium honey‐mediated gut homeostasis and anti‐inflammation via Thorl/Nprl2‐TORC1 signaling: Network pharmacology and Drosophila validation

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The study employed a four‐tiered strategy: (1) UHPLC‐FTMS profiling of Citrus aurantium honey to characterize its chemical composition; (2) network pharmacology analysis integrating target prediction, protein–protein interaction networks, and KEGG pathway enrichment to identify the Thor1/Nprl2‐TORC1 axis as a key mechanistic pathway; (3) in vitro ...

AND‐Logic‐Gated Aptamer Switch for Precise Targeting and Regulation of RNA G‐Quadruplexes

open access: yesAngewandte Chemie, EarlyView.
An AND‐logic‐gated aptamer switch enables tumor‐selective activation of RNA G‐quadruplex (rG4)‐targeting function. By combining cell‐surface recognition and intracellular redox sensing, the system achieves precise regulation of disease‐relevant RNA structures exclusively in tumor cells, with minimal off‐target effects in normal cells, offering a ...

Positive Electrochemical Potentials Induce Enhanced Chemoselectivity and Activity in the Thermocatalytic Hydrogenation of 3‐Nitrostyrene

open access: yesAngewandte Chemie, EarlyView.
Induced by positive electrochemical potentials, thermocatalytic hydrogenation (TCH) of 3‐nitrostyrene with H2 delivers one single product with six‐fold enhanced yield. The enhanced selectivity and activity originate from changes in the adsorption geometry of 3‐nitrostyrene and in the surface concentration of 3‐nitrostyrene and hydrogen via a concurrent
