Deciphering the Evolution of Cephalosporin Resistance to Ceftolozane-Tazobactam in Pseudomonas aeruginosa

open access: yesmBio, 2018
Pseudomonas aeruginosa produces a class C β-lactamase (e.g., PDC-3) that robustly hydrolyzes early generation cephalosporins often at the diffusion limit; therefore, bacteria possessing these β-lactamases are resistant to many β-lactam antibiotics.

Neutralizing Carbapenem Resistance by Co-Administering Meropenem with Novel β-Lactam-Metallo-β-Lactamase Inhibitors

open access: yesAntibiotics, 2023
Virulent Enterobacterale strains expressing serine and metallo-β-lactamases (MBL) genes have emerged responsible for conferring resistance to hard-to-treat infectious diseases. One strategy that exists is to develop β-lactamase inhibitors to counter this

Optimization of β-Lactam/β-Lactamase Inhibitor Dosing

open access: yes, 2020
Infections caused by extended-spectrum β-lactamase (ESBL)-producing Gram-negative bacteria are associated with increased mortality and cost of care.

N-Nitroso-β-lactams as β-lactamase inhibitor [PDF]

open access: yes, 1989
N-Nitroso-β-phenyl-β-lactam has been found to be a specific inhibitor of β-lactamase. N-Nitroso-α-phenyl-β-lactam, by contrast, was virtually ineffective although a transient inhibition of short duration was observed.

Insight into the effect of inhibitor resistant S130G mutant on physico-chemical properties of SHV type beta-lactamase: a molecular dynamics study.

open access: yesPLoS ONE, 2014
Bacterial resistance is a serious threat to human health. The production of β-lactamase, which inactivates β-lactams is most common cause of resistance to the β-lactam antibiotics.

Sulbactam-containing β-lactamase inhibitor combinations [PDF]

open access: yes, 2008
Sulbactam irreversibly inhibits the hydrolytic activity of β-lactamases. This compound is commercially available in combination with either ampicillin or cefoperazone. In each instance, the activity of the partner antibiotic against β-lactamase-producing

The Preparation of Novel Fluorenes Inspired by Hipposudoric Acid

open access: yesHelvetica Chimica Acta, EarlyView.
In this research we report on the design and synthesis of a series of fluorene‐based derivatives loosely inspired by the tricyclic framework of hipposudoric acid. Preparation of sixteen novel N‐alkylated derivatives was accomplished via a series of concise one‐step amide N‐alkylation reactions.

Motion pattern of the complex involved in klebsiella pneumoniae carbapenemases and β-Lactamase inhibitor protein

open access: yes四川大学学报. 自然科学版, 2017
Carbapenems, used in clinical treatment of multi-drug resistance bacterial infection, can be hydrolyzed by Klebsiella pneumoniae carbapenemases, which weaken the treatment effect of gram negative bacterial infection.
