recommendations! Published in 2021 at "Advanced drug delivery reviews"

DOI: 10.1016/j.addr.2021.02.014

Abstract: To win the battle against resistant, pathogenic bacteria, novel classes of anti-infectives and targets are urgently needed. Bacterial uptake, distribution, metabolic and efflux pathways of antibiotics in Gram-negative bacteria determine what we here refer to… read more here.

DOI: 10.1016/j.jiph.2021.11.008

Abstract: BACKGROUND Progressive decline of immune response in HIV patients makes them susceptible to frequent bacterial infections. High usage of antibiotics influences the emergence of multidrug-resistant bacteria and worsens the clinical outcomes. In this study, the… read more here.

DOI: 10.1021/acs.chemrev.0c01005

Abstract: Iron is an indispensable metabolic cofactor in both pro- and eukaryotes, which engenders a natural competition for the metal between bacterial pathogens and their human or animal hosts. Bacteria secrete siderophores that extract Fe3+ from… read more here.

DOI: 10.1021/acs.jmedchem.3c01584

Abstract: Insect defensins are a large family of antimicrobial peptides primarily active against Gram-positive bacteria. Here, we explore their hidden anti-Gram-negative bacterial potential via a nature-guided strategy inspired by natural deletion variants of Drosophila defensins. Referring… read more here.

recommendations! Published in 2019 at "Journal of medicinal chemistry"

DOI: 10.1021/acs.jmedchem.8b01357

Abstract: The presence of lipopolysaccharide and emergence of drug resistance make the treatment of Gram-negative bacterial infections highly challenging. Herein, we present the synthesis and antibacterial activities of cholic acid-peptide conjugates (CAPs), demonstrating that valine-glycine dipeptide-derived… read more here.

recommendations! Published in 2020 at "Open Forum Infectious Diseases"

DOI: 10.1093/ofid/ofaa051

Abstract: Abstract Fourty patients were treated with meropenem-vaborbactam (MEV) for serious Gram-negative bacterial (GNB) infections. Carbapenem-resistant Enterobacteriaceae (CRE) comprised 80.0% of all GNB infections. Clinical success occurred in 70.0% of patients. Mortality and recurrence at 30… read more here.
