Relationship between continuous infusion meropenem PK/PD target attainment and C‐reactive protein dynamics in onco‐haematologic patients with febrile neutropenia

British Journal of Clinical Pharmacology, EarlyView.
Aim Meropenem is a second‐line antimicrobial agent in the treatment of febrile neutropenia in onco‐haematological patients. A population pharmacokinetic/pharmacodynamic (PK/PD) analysis for assessing the relationship between meropenem exposure and C‐reactive protein (C‐RP) over time was conducted.

Extrapolation and pharmacokinetic protocol design optimization for ceftriaxone as an exemplar for the development of antibiotics for children

British Journal of Clinical Pharmacology, EarlyView.
Aim Ceftriaxone is a cephalosporin commonly used for the treatment of acute, severe infections; however, there are conflicting data on its disposition properties in children, making it a suitable case study for the evaluation of the appropriateness of extrapolation approaches based on exposure matching principles for paediatric patients and exploring ...

Structural shifts in TolC facilitate Efflux-Mediated β-lactam resistance

Communications Biology
Efflux-mediated β-lactam resistance is a major public health concern, reducing the effectiveness of β-lactam antibiotics against many bacteria. Structural analyses show the efflux protein TolC in Gram-negative bacteria acts as a channel for antibiotics ...

Cefepime exposure in prolonged or intermittent infusion in critically ill children

British Journal of Clinical Pharmacology, EarlyView.
Aims Cefepime is commonly used in critically ill children for whom there is a high between‐subject variability. To reach the therapeutic pharmacokinetic (PK) target in critically ill patients, prolonged infusion of beta‐lactams seems to be the most efficient.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Bifunctional Beta-Lactam Antibiotics

, 2021
The molecular structure of β-lactam antibiotics can be modified either to introduce another β-lactam ring (the pharmacophore conferring bactericidal activities to these molecules), or to add other pharmacophores that modify their pharmacological ...

Clinical Model‐Informed Precision Dosing Consult Service for Accelerating Personalized Medication in Pediatric Patients

Clinical Pharmacology &Therapeutics, EarlyView.
Traditional dosing strategies often rely on a “one‐size‐fits‐all” paradigm, assuming an “average” patient with typical demographic and pharmacological characteristics. In reality, this often overlooks existing between‐patient variability and can lead to suboptimal drug exposure or toxicity. This issue is especially pronounced in pediatric patients, who

Synthetic Lethality Reveals Mechanisms of Mycobacterium tuberculosis Resistance to β-Lactams

mBio, 2014
Most β-lactam antibiotics are ineffective against Mycobacterium tuberculosis due to the microbe’s innate resistance. The emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains has prompted interest to repurpose this class of ...
