Drug development concerning metallo-β-lactamases in gram-negative bacteria [PDF]

Frontiers in Microbiology, 2022
β-Lactams have been a clinical focus since their emergence and indeed act as a powerful tool to combat severe bacterial infections, but their effectiveness is threatened by drug resistance in bacteria, primarily by the production of serine- and metallo-β-

Evolution of Metallo-β-lactamases: Trends Revealed by Natural Diversity and in vitro Evolution

Antibiotics, 2014
The production of β-lactamase enzymes is one of the most distributed resistance mechanisms towards β-lactam antibiotics. Metallo-β-lactamases constitute a worrisome group of these kinds of enzymes, since they present a broad spectrum profile, being able

Dynamically chiral phosphonic acid-type metallo-β-lactamase inhibitors

Communications Chemistry
Antibiotic resistance is a growing global health threat that risks the lives of millions. Among the resistance mechanisms, that mediated by metallo-β-lactamases is of particular concern as these bacterial enzymes dismantle most β-lactam antibiotics ...

Discovery of potential inhibitors against New Delhi metallo-β-lactamase-1 from natural compounds: in silico-based methods

Scientific Reports, 2021
New Delhi metallo-β-lactamase variants and different types of metallo-β-lactamases have attracted enormous consideration for hydrolyzing almost all β-lactam antibiotics, which leads to multi drug resistance bacteria.

Carbapenem-Resistant Klebsiella pneumoniae in Large Public Acute-Care Healthcare System, New York, New York, USA, 2016–2022

Emerging Infectious Diseases, 2023
Controlling the spread of carbapenem-resistant Enterobacterales is a global priority. Using National Healthcare Safety Network data, we characterized the changing epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) in a large public health

Novel metallo β-lactamase mediated by aShigella flexneriplasmid [PDF]

FEMS Microbiology Letters, 1998
Novel carbapenem-hydrolyzing beta-lactamase (newly named MET-1) encoded on a transferable plasmid pMS390 from Shigella flexneri JS19622 was purified. The molecular weight was 28,000 by SDS-PAGE and the isoelectric point was higher than 9.3. This beta-lactamase favorably hydrolyzed classical cephalosporins and oxyimino-cephalosporins rather than ...

Could β-Lactam Antibiotics Block Humoral Immunity?

Frontiers in Immunology, 2021
It has been reported that treatment with β-lactam antibiotics induces leukopenia and candidemia, worsens the clinical response to anticancer immunotherapy and decreases immune response to vaccination.
