Evolved DNAzymes and Stable Activation Chemistry Enable High‐Efficiency DNA Ligation
In vitro selection of pre‐structured DNA libraries and chemical screening of alternative activation groups yielded trans‐acting DNAzymes with faster ligation rates and enhanced DNA substrate stability. The combination of C3S1 DNAzymes and phosphobenzimidazole‐activated DNA substrates provides improved DNA ligation performance, offering promise for ...

Self‐Calibrating Ratiometric DNA Aptamer Probe for Quantitative ATP Imaging in Living Cells
We developed the RFA–ECHO probe, an internally calibrated ATP sensor that remains responsive across millimolar ATP levels. Its self‐correcting Cy5/ECHO ratio ensures accurate quantification independent of probe uptake. Compared with FRET‐based sensors, it yields a robust ratiometric shift, distinguishing high‐ATP cancer cells from normal ones, enabling

5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

Thiopurine methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) are key enzymes that catabolize thiopurines. Decreased or no‐function alleles in TPMT and NUDT15 are associated with reduced or no enzyme activity and predictive of pronounced adverse effects, including severe myelosuppression, that may occur among individuals treated with standard ...

Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

This study exploits the comparable binding tolerances between the fluorinase enzyme and the A2A adenosine receptor towards the development of novel C‐2 functionalised 5′‐fluorodeoxy‐adenosine (FDA)‐based agonists with enzymatic 18F‐labelling capability for positron emission tomography (PET).
