Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

Chemistry – A European Journal, EarlyView.
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.

Purine and pyrimidine synthesis differently affect the strength of the inoculum effect for aminoglycoside and β-lactam antibiotics

Microbiology Spectrum
The inoculum effect has been observed for nearly all antibiotics and bacterial species. However, explanations accounting for its occurrence and strength are lacking.

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications

Chemistry – A European Journal, EarlyView.
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 ...

Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for Thiopurine Dosing Based on TPMT and NUDT15 Genotypes: 2025 Update

Clinical Pharmacology &Therapeutics, EarlyView.
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 ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
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.

The Characterization of the Purine Nucleoside Phosphorylase from Agaricus bisporus and Its Potential Application in Reducing Purine Content in Beer

Journal of Fungi
Beer, the most popular alcoholic beverage, poses health risks for individuals with gout and hyperuricemia due to its high purine content. Herein, we identified a novel purine nucleoside phosphorylase (AbPNP) from the edible mushroom Agaricus bisporus and

A2A Adenosine Receptor Agonists With Last‐Step Enzymatic 18F‐Labelling Potential (Fluorinase) for Positron Emission Tomography (PET)

European Journal of Organic Chemistry, EarlyView.
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).
