Abstract
β-lactamase, an enzyme secreted by bacteria, is the main resistant mechanism of Gram-negative bacteria to β-lactam antibiotics. The resistance of bacteria to β-lactam antibiotics can be evaluated by testing the activity of β-lactamase. Traditional phenotypic detection is a golden principle, but it is time-consuming. In recent years, many new methods have emerged, which improve the efficiency by virtue of their sensitivity, low cost, easy operation, and other advantages. In this paper, we systematically review these researches and emphasize their limits of detection, sample operation, and test duration. Noteworthily, some detection systems can identify the β-lactamase subtype conveniently. We mainly divide these tests into three categories to elaborate their characteristics and application status. Both advantages and disadvantages of these methods are discussed. Additionally, we analyze the recent 5 years published researches to predict the trend of development in this field.

Abstract
β-lactam antibiotics are one of the most widely used and diverse classes of antimicrobial agents for treating both Gram-negative and Gram-positive bacterial infections. The β-lactam antibiotics, which include penicillins, cephalosporins, monobactams and carbapenems, exert their antibacterial activity by inhibiting the bacterial cell wall synthesis and have a global positive impact in treating serious bacterial infections. Today, β-lactam antibiotics are the most frequently prescribed antimicrobial across the globe. However, due to the widespread use and misapplication of β-lactam antibiotics in fields such as human medicine and animal agriculture, resistance to this superlative drug class has emerged in the majority of clinically important bacterial pathogens. This heightened antibiotic resistance prompted researchers to explore novel strategies to restore the activity of β-lactam antibiotics, which led to the discovery of β-lactamase inhibitors (BLIs) and other β-lactam potentiators. Although there are several successful β-lactam-β-lactamase inhibitor combinations in use, the emergence of novel resistance mechanisms and variants of β-lactamases have put the quest of new β-lactam potentiators beyond precedence. This review summarizes the success stories of β-lactamase inhibitors in use, prospective β-lactam potentiators in various phases of clinical trials and the different strategies used to identify novel β-lactam potentiators. Furthermore, this review discusses the various challenges in taking these β-lactam potentiators from bench to bedside and expounds other mechanisms that could be investigated to reduce the global antimicrobial resistance (AMR) burden.

Abstract
The emergence of antibiotic resistance has prompted the development of rapid antimicrobial susceptibility testing (AST) technologies to guide antibiotic prescription. A novel electrochemiluminescence (ECL) biosensor developed can quantitatively measure the binding between the lectin and lipopolysaccharide (LPS) on Gram-negative bacteria for bacterial determination and to characterize the antimicrobial activities of β-lactam and non-β-lactam antibiotics to normal and antibiotic-resistant bacteria. The biosensor utilizes ruthenium complex tagged concanavalin A (Ru-Con A) coated on NH2-MIL-53(Al) interface for LPS binding measurements. The decreased ECL signal obtained was directly proportional to increasing Escherichia coli (E. coli) BL21 concentrations. The sensitivity displayed logarithmic dependence in the range of (50-5.0) × 104 cells/mL, with a detection limit of 16 cells/mL. The minimum inhibitory concentration (MIC) values of antibiotics for normal E. coli BL21 were 0.02-0.2, 2-4, 0.002-0.02, and 0.2-1 mg/L for levofloxacin hydrochloride (LVX), tetracycline (TCY), imipenem (IPM), and cefpirome (CPO), respectively. The increased MIC values (8-16 and 4 mg/L for IMP and CPO, respectively) in New Delhi metallo-β-lactamase-1 expressing E. coli BL21 (NDM-1-E. coli BL21) indicated greater resistance to β-lactams in NDM-1-E. coli BL21 compared with normal E. coli BL21. Therefore, the changed ECL signal because of binding between LPS with the lectin has a relation with the type of antibiotic and bacterial strains, making the ECL biosensor promote clinical practicability and facilitate antibiotic stewardship.

Abstract
We introduce a real-time quantitative analytical method for universal silver ions (Ag(I)) and silver nanoparticles (AgNPs) analysis based on a portable nanozyme catalysis-powered portable mini-drainage device. The device is composed of three main glass containers with different specifications. The catalase mimic of ascorbic acid-coated platinum nanoparticles (AA-PtNPs) was used to provide the pumping power to drain water by catalyzing a gas-generation reaction, and the inhibition effect of Ag(I) on the catalytic activity of AA-PtNPs is adopted to connect the target detection event with the mini-drainage device. Experimental results reveal that the mass of the overflowed water is inversely proportional to the concentration of Ag(I) and AgNPs so that their quantitation can be accomplished via real-time weighing of the overflowed water. The importance is that without requiring advanced instruments, this device can quantify Ag(I) and AgNPs with a limit of detection (LOD) of 2.0 nM for Ag(I), and 3.8 pM for AgNPs within 30 min, respectively. The reliability and accuracy are comparable with the inductively coupled plasma optical emission spectrometer (ICP-OES). All these appealing features provide us a remarkable insight into the design of versatile portable devices with potential applications in in-situ environmental monitoring under remote areas and resource-limited settings.

A Degradation Product from Hydrolysate of Imipenem with Imis Broad-Spectrum Inhibits Metallo-β-Lactamases. Jundishapur J Microbiol 2020.

Abstract
Background: Infections caused by metallo-β-lactamases (MβLs)-producing antibiotic-resistant bacteria pose a severe threat to public health. The synergistic use of current antibiotics in combination with MβL inhibitors is a promising therapeutic mode against these antibiotic-resistant bacteria. Objectives: The study aimed to probe the inhibition of MβLs and obtain the active component, P1, in the degradation product after imipenem was hydrolyzed by ImiS. Methods: The hydrolysis of two carbapenems with MβL ImiS was monitored by UV-Vis in real-time, and the degradation product from the leaving group produced after imipenem was hydrolyzed (but not for faropenem) was purified by HPLC to give one component, P1. Results: Kinetic assays revealed that P1 exhibited a broad-spectrum inhibition against VIM-2, NDM-1, ImiS, and L1, from three sub-classes of MβLs, with IC50 values of 8 - 32, 13.8 - 29.3, and 14.2 - 19.2 µM, using imipenem, cefazolin, and nitrocefin as substrates, respectively. Also, P1 showed synergistic antibacterial efficacy against drug-resistant Escherichia coli producing VIM-2, NDM-1, ImiS, and L1, in combination with antibiotics, restoring 16 to 32-fold and 32 to 128-fold efficacies of imipenem and cefazolin, respectively. Spectroscopic and Ellman's reagent analyses suggested that P1, a mercaptoethyl-form imidamide, is a mechanism-based inhibitor, while faropenem has no substrate inhibition, due to the lack of a leaving group. Conclusions: This work reveals that the hydrolysate of imipenem, a carbapenem with a good leaving group, can be used in screening for broad-spectrum inhibitors of MβLs.

Abstract
The emergence and prevalence of carbapenem-resistant bacterial infection have seriously threatened the clinical use of almost all β-lactam antibacterials. The development of effective metallo-β-lactamase (MβL) inhibitors to restore the existing antibiotics efficacy is an ideal alternative. Although several types of serine-β-lactamase inhibitors have been successfully developed and used in clinical settings, MβL inhibitors are not clinically available to date. Herein, we identified that cisplatin and Pd(II) complexes are potent broad-spectrum inhibitors of the B1 and B2 subclasses of MβLs and effectively revived Meropenem efficacy against MβL-expressing bacteria in vitro. Enzyme kinetics, thermodynamics, inductively coupled plasma atomic emission spectrometry (ICP-AES), matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS), and site-directed mutation assays revealed that these metal complexes irreversibly inhibited NDM-1 through a novel inhibition mode involving binding to Cys208 and displacing one Zn(II) ion of the enzyme with one Pt(II) containing two NH3's or one Pd(II) ion. Importantly, the combination therapy of Meropenem and metal complexes significantly suppressed the development of higher-level resistance in bacteria producing NDM-1, also effectively reduced the bacterial burden in liver and spleen of mice infected by carbapenem-resistant Enterobacteriaceae producing NDM-1. These findings will offer potential lead compounds for the further development of clinically useful inhibitors targeting MβLs.

Abstract
The "superbug" infection caused by New Delhi metallo-β-lactamase (NDM-1) has become an emerging threat. Monitoring NDM-1 has proven challenging due to its shuttling between pathogenic bacteria. Here, we report an isothermal titration calorimetry (ITC) method that can monitor activity and inhibition of NDM-1 in live bacterial cells in real time. This method has been exemplified by monitoring of the activity and inhibition of the target enzyme and evaluating the breakdown of antibiotics by pathogenic bacteria expressing β-lactamases. Cell-based studies demonstrate that the NDM-1 expressed in bacterial cells was inhibited by four known inhibitors ethylene diamine tetraacetic acid (EDTA), d-captopril, ebselen and azolylthioacetamide with fifty percent inhibitory concentration (IC50) values of 3.8, 48, 0.55, and 17.5 μM, respectively, which are in good agreement with the data from inhibition kinetics using UV-vis and NMR spectroscopy in vivo. This approach could be applied to screen and evaluate small molecule inhibitors of metallo-β-lactamases (MβLs) in whole cells or to identify drug resistant bacteria.

Abstract
The New Delhi metallo-β-lactamase (NDM-1) is an important clinical target for antimicrobial research, but there are insufficient clinically useful inhibitors and the details of NDM-1 enzyme catalysis remain unclear. The aim of this work is to provide a thermodynamic profile of NDM-1 catalysed hydrolysis of β-lactams using an isothermal titration calorimetry (ITC) approach and to apply this new method to the identification of new low-molecular-weight dicarboxylic acid inhibitors. The results reveal that hydrolysis of penicillin G and imipenem by NDM-1 share the same thermodynamic features with a significant intrinsic enthalpy change and the release of one proton into solution, while NDM-1 hydrolysis of cefazolin exhibits a different mechanism with a smaller enthalpy change and the release of two protons. The inhibitory constants of four carboxylic acids are found to be in the micromolar range. The compounds pyridine-2,6-dicarboxylic acid and thiazolidine-2,4-dicarboxylic acid show the best inhibitory potency and are confirmed to inhibit NDM-1 using a clinical strain of Escherichia coli The pyridine compound is further shown to restore the susceptibility of this E. coli strain to imipenem, at an inhibitor concentration of 400 μM, while the thiazoline compound also shows a synergistic effect with imipenem. These results provide valuable information to enrich current understanding on the catalytic mechanism of NDM-1 and to aid the future optimisation of β-lactamase inhibitors based on these scaffolds to tackle the problem of antibiotic resistance.

Abstract
The emergence of antibiotic resistance caused by β-lactamases, including serine β-lactamases (SβLs) and metallo-β-lactamases (MβLs), is a global public health threat. L1, a B3 subclass MβL, hydrolyzes almost all of known β-lactam antibiotics. We report a simple and straightforward UV-Vis approach for real-time activity assays of β-lactamases inside living bacterial cells, and this method has been exemplified by choosing antibiotics, L1 enzyme, Escherichia coli expressing L1 (L1 E. coli), Escherichia coli expressing extended-spectrum β-lactamases (ESBL-E. coli), clinical bacterial strains, and reported MβL and SβL inhibitors. The cell-based studies demonstrated that cefazolin was hydrolyzed by L1 E. coli and clinical strains, and confirmed the hydrolysis to be inhibited by two known L1 inhibitors EDTA and azolylthioacetamide (ATAA), with an IC50 value of 1.6 and 18.9 μM, respectively. Also, it has been confirmed that the breakdown of cefazolin caused by ESBL-E. coli was inhibited by clavulanic acid, the first SβL inhibitor approved by FDA. The data gained through this approach are closely related to the biological function of the target enzyme in its physiological environment. The UV-Vis method proposed here can be applied to target-based whole-cell screening to search for potent β-lactamase inhibitors, and to assays of reactions in complex biological systems, for instance in medical assays.
