Studying Target-Engagement of Anti-Infectives by Solvent-Induced Protein Precipitation and Quantitative Mass Spectrometry.

Antimicrobial resistance (AMR) poses a serious threat to global health. The rapid emergence of resistance contrasts with the slow pace of antimicrobial development, emphasizing the urgent need for innovative drug discovery approaches. This study addresses a critical bottleneck in early drug development by introducing integral solvent-induced protein precipitation (iSPP) to rapidly assess the target-engagement of lead compounds in extracts of pathogenic microorganisms under close-to-physiological conditions.

Targeting the IspE Enzyme.

The enzyme IspE in is considered an attractive drug target, as it is essential for parasite survival and is absent in the human proteome. Yet it still has not been addressed by a small-molecule inhibitor. In this study, we conducted a high-throughput screening campaign against the IspE enzyme.

IspE kinase as an anti-infective target: Role of a hydrophobic pocket in inhibitor binding.

Enzymes of the methylerythritol phosphate (MEP) pathway are potential targets for antimicrobial drug discovery. Here, we focus on 4-diphosphocytidyl-2-C-methyl-D-erythritol (IspE) kinase from the MEP pathway. We use biochemical and structural biology methods to investigate homologs from pathogenic microorganisms; Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii.

[Securing the management of medicines at risk in a geriatric hospital: A comprehensive approach].

High-risk drugs, which are potentially a source of serious adverse reactions, are a major concern in healthcare establishments, particularly for geriatric patients, who often have multiple medications and co-morbid conditions. With a view to continuously improving the quality and safety of care, we have embarked on a proactive approach aimed at identifying, securing and improving the management of medicines at risk in geriatric wards.

The effects of moderate prenatal alcohol exposure on performance in hippocampal-sensitive spatial memory and anxiety tasks by adult male and female rat offspring.

Moderate prenatal alcohol exposure (mPAE) results in structural alterations to the hippocampus. Previous studies have reported impairments in hippocampal-sensitive tasks, but have not compared performance between male and female animals. In the present study, performance in hippocampal-sensitive spatial memory and anxiety behavior tests were compared across adult male and female saccharin (SACC) control mPAE Long-Evans rat offspring.
