Exploiting the aggregation propensity of beta-lactamases to design inhibitors that induce enzyme misfolding

open access: yesNature Communications, 2023
There is an arms race between beta-lactam antibiotics development and co-evolving beta-lactamases, which provide resistance by breaking down beta-lactam rings.

Cefonicid: A stable .BETA.-lactamase inhibitor.

open access: yesThe Journal of Antibiotics, 1981
The stability of cefonicid (SK&F 75073) towards representatives of six major classes of beta-lactamases was determined using a spectrophotometric assay. Cefonicid was stable to hydrolysis by the Type I enzyme from Enterobacter cloacae and by the enzyme from the anaerobe, Bacteroides fragilis. It was 6 to 7 times more stable than cefamandole to the Type

Approachable Synthetic Methodologies for Second-Generation β-Lactamase Inhibitors: A Review [PDF]

open access: yes
Some antibiotics that are frequently employed are β-lactams. In light of the hydrolytic process of β-lactamase, found in Gram-negative bacteria, inhibitors of β-lactamase (BLIs) have been produced.

The ideal patient profile for new beta-lactam/beta-lactamase inhibitors [PDF]

open access: yes, 2018
PURPOSE OF REVIEW: The worldwide spread of extended-spectrum beta-lactamase (ESBL)-producing bacteria, the overuse of carbapenems, the emergence of carbapenemase-producing organisms and the growing importance of multidrug-resistant and/or extended drug ...

Carbapenem-sparing beta-lactam/beta-lactamase inhibitors versus carbapenems for bloodstream infections caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae: a systematic review and meta-analysis

open access: yesInternational Journal of Infectious Diseases, 2023
Objectives: Bloodstream infections (BSIs) caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) have become a worldwide public health threat, and beta-lactam/beta-lactamase inhibitor combinations (BLBLIs) are considered as one

In Vitro Susceptibilities of Capnocytophaga Isolates to β-Lactam Antibiotics and β-Lactamase Inhibitors [PDF]

open access: yes, 2000
The susceptibilities of 43 pharyngeal isolates of Capnocytophaga to beta-lactam antibiotics, alone or in combination with beta-lactamase inhibitors, were tested by an agar dilution method.

Diketene analogs as .BETA.-lactamase inhibitor.

open access: yesChemical and Pharmaceutical Bulletin, 1989
Compounds having a structural analogy with diketene have been synthesized and their potencies as beta-lactamase inhibitors have been studied. Among six compounds so far tested, alpha-phenyl-beta-benzylidene-3-propanolide was shown to be an irreversible inhibitor of the enzyme. The availability of simple monocyclic compounds as beta-lactamase inhibitors

High‐Density E. Coli Cultivation Arrays for Combinatorial Drug Testing With Subsequent Lipid Profiling by MALDI‐MS

open access: yesAdvanced Science, EarlyView.
High‐throughput antibiotic cross‐gradient assays on microdroplet arrays. A multichannel printhead together with five pressure regulators forms droplet arrays of up to 20 832 droplets within 25 minutes. Each droplet contains unique concentrations of antibiotics, allowing to moniture a vast spectrum of bacterial repsonses over night. The bacterial growth

Cyclobutanone analogues of beta‐lactam antibiotics: beta‐lactamase inhibitors with untapped potential? [PDF]

open access: yes, 2016
Beta‐Lactam antibiotics have been used for many years to treat bacterial infections. However the effective treatment of an increasing range of microbial infections is threatened by bacterial resistance to beta‐lactams: the ...
