Recent Developments to Cope the Antibacterial Resistance via β-Lactamase Inhibition

Molecules, 2022
Antibacterial resistance towards the β-lactam (BL) drugs is now ubiquitous, and there is a major global health concern associated with the emergence of new β-lactamases (BLAs) as the primary cause of resistance.

Evaluation of inhibitory action of novel non β-lactam inhibitor against Klebsiella pneumoniae carbapenemase (KPC-2). [PDF]

PLoS ONE, 2014
The use of three classical β-lactamase inhibitors (Clavulanic acid, tazobactam and sulbactam) in combination with β-lactam antibiotics is presently the mainstay of antibiotic therapy against Gram-negative bacterial infections.

Multiparametric determination of genes and their point mutations for identification of beta-lactamases [PDF]

, 2010
More than half of all currently used antibiotics belong to the beta-lactam group, but their clinical effectiveness is severely limited by antibiotic resistance of microorganisms that are the causative agents of infectious diseases. Several mechanisms for

Phosphonopeptides Revisited, in an Era of Increasing Antimicrobial Resistance [PDF]

, 2020
Given the increase in resistance to antibacterial agents, there is an urgent need for the development of new agents with novel modes of action. As an interim solution, it is also prudent to reinvestigate old or abandoned antibacterial compounds to assess

Dynamic energy budget approach to evaluate antibiotic effects on biofilms [PDF]

, 2017
Quantifying the action of antibiotics on biofilms is essential to devise therapies against chronic infections. Biofilms are bacterial communities attached to moist surfaces, sheltered from external aggressions by a polymeric matrix.
