Functional dynamics of water in New Delhi metallo‐β‐lactamase catalysis

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Water plays a critical role in the hydrolysis of antibiotics by New Delhi metallo‐β‐lactamases (NDMs). The reaction proceeds through a nucleophilic attack on the β‐lactam ring, followed by cleavage of the C–N bond and formation of an anionic nitrogen intermediate. This intermediate is then protonated by a water molecule diffusing from the bulk

Evaluating the Educational Value of Artificial Intelligence in Pharmacotherapy Education

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Final‐year medical students frequently make prescribing errors, partly because they have had insufficient training in therapeutic reasoning. Students need to understand the underlying rationale behind a drug choice in order to subsequently apply that knowledge critically and independently.

A novel fusion tool to enable G protein‐coupled receptor structure determination

Acta Crystallographica Section D, Volume 82, Issue 6, Page 655-663, June 2026.
The development of a new fusion tool in which a β‐lactamase fusion tag and a binding partner enabled the structure determination of an antagonist‐bound G protein‐coupled receptor by cryo‐EM is reported.Structure determination of G protein‐coupled receptors (GPCRs) plays an important role in accelerating drug development against this medically important

Cefdinir binding to a class A β‐lactamase revealed by serial cryo‐crystallography

Acta Crystallographica Section D, Volume 82, Issue 6, Page 672-682, June 2026.
Serial cryo‐crystallography reveals the structure of the extended‐spectrum β‐lactamase CTX‐M‐14 in complex with the third‐generation cephalosporin antibiotic cefdinir.One of the most common resistance mechanisms against antibiotics employed by Gram‐negative bacteria involves the production of β‐lactamases, resulting in rapid hydrolysis of the ...

Species‐Specific Optimisation and Environmental Regulation of Biofilm Formation in Enterobacter cloacae: Inhibitory Role of Glucose in Biofilm Development

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
This study demonstrates that mild salinity stress (1%–2% NaCl) significantly enhances biofilm formation in Enterobacter cloacae. Using a standardised 96‐well microtiter plate assay, we optimised in vitro biofilm quantification and classification, providing a reproducible framework for studying environmental and clinical biofilm development mechanisms ...

Altered Pathogen Spectrum of Spontaneous Bacterial Peritonitis in Patients Treated With Proton Pump Inhibitors

Alimentary Pharmacology &Therapeutics, Volume 63, Issue 11, Page 1487-1494, June 2026.
This multicenter, observational study reveals distinct alterations in the microbial spectrum of spontaneous bacterial peritonitis (SBP) associated with proton pump inhibitor use. These results are especially relevant for guiding empiric antibiotic therapy of SBP.

Effects of Nacubactam and Its Metabolites on QTc Interval: A Pooled Analysis of Two Randomized Phase 1 Studies

Clinical and Translational Science, Volume 19, Issue 6, June 2026.
ABSTRACT Nacubactam is a β‐lactamase inhibitor. Early‐phase studies with 1000/2000/4000/8000 mg nacubactam monotherapy were not powered to assess proarrhythmic risk. Therefore, this analysis pooled electrocardiogram data from two placebo‐controlled studies to quantify potential effects of nacubactam on cardiac repolarization.

Exploring the Antimicrobial Efficacy of Mesenchymal Stem Cell Secretome Against Klebsiella pneumoniae in Urinary Tract Infections

Clinical and Translational Science, Volume 19, Issue 6, June 2026.
ABSTRACT Antimicrobial resistance (AMR) has become a global health crisis, with Klebsiella pneumoniae (K. pneumoniae) emerging as a major driver of AMR and a leading cause of urinary tract infections (UTIs). Mesenchymal stem cell (MSC)‐derived secretomes have gained attention for their antimicrobial properties.
