Int J Biol Macromol 2023; 252:126441. [PMID: 37607651 DOI: 10.1016/j.ijbiomac.2023.126441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 07/08/2023] [Accepted: 08/18/2023] [Indexed: 08/24/2023]
Abstract
Metallo-carbapenemases-mediated carbapenem-resistant Enterobacterales (CREs) has been acknowledged as "urgent threat" by the World Health Organization. The discovery of new strategies that block metallo-carbapenemases activity to reverse carbapenem resistance is an urgent need. In this study, a coumarin copper complex containing a PEG linker and glucose ligand, GluC-Cu, was used to reverse carbapenem resistance. Interestingly, it could effectively inhibit metallo-carbapenemases (NDM-1, IMP-1 and ImiS) with an IC50 value in the range of 0.23-1.21 μM, and simultaneously release the green fluorescence signal (GluC), therefore exhibiting self-reported inhibition performance. The inhibition mechanism of oxidizing Zn(II) thiolate site of NDM-1 from Cu2+ to Cu+ was verified by fluorescence assay, HR-MS, and XPS. Moreover, GluC-Cu in combination with meropenem showed excellent synergistic antibacterial effect to effectively combat E. coli expressing metallo-carbapenemases in vitro and in a mice infection model. This bifunctional metallo-carbapenemases inhibitor provides a novel chemical tool to overcome carbapenem resistance.

Design, Synthesis, and Biological Evaluation of New 1H-Imidazole-2-Carboxylic Acid Derivatives as Metallo-β-Lactamase Inhibitors. Bioorg Med Chem 2022; 72:116993.

Abstract
As one of important mechanisms to β-lactam antimicrobial resistance, metallo-β-lactamases (MBLs) have been receiving increasing worldwide attentions. Ambler subclass B1 MBLs are most clinically relevant, because they can hydrolyze almost all β-lactams with the exception of monobactams. However, it is still lacking of clinically useful drugs to combat MBL-medicated resistance. We previously identified 1H-imidazole-2-carboxylic acid as a core metal-binding pharmacophore (MBP) to target multiple B1 MBLs. Herein, we report structural optimization of 1H-imidazole-2-carboxylic acid and substituents. Structure-activity relationship (SAR) analyses revealed that replacement of 1H-imidazole-2-carboxylic acid with other structurally highly similar MBPs excepting thiazole-4-carboxylic acid resulted in decreased MBL inhibition. Further SAR studies identified more potent inhibitors to MBLs, of which 28 manifested IC50 values of 0.018 µM for both VIM-2 and VIM-5. The microbiological tests demonstrated that the most tested compounds showed improved synergistic effects; some compounds at 1 µg/ml were able to reduce meropenem MIC by at least 16-fold, which will be worth further development of new potent inhibitors particularly targeting VIM-type MBLs.

Abstract
The effectiveness of β-lactam antibiotics is increasingly influenced by serine β-lactamases (SBLs) and metallo-β-lactamases (MBLs), which can hydrolyze β-lactam antibiotics. The development of effective β-lactamase inhibitors is an important direction to extend use of β-lactam antibiotics. Although six SBL inhibitors have been approved for clinical use, but no MBL inhibitors or MBL/SBL dual-action inhibitors are available so far. Broad-spectrum targeting clinically relevant MBLs and SBLs is currently desirable, while it is not easy to achieve such a purpose owing to structural and mechanistic differences between MBLs and SBLs. In this review, we summarized recent advances of inhibitor chemotypes targeting MBLs and SBLs and their inhibition mechanisms, particularly including lead discovery and structural optimization strategies, with the aim to provide useful information for future efforts to develop new MBL and SBL inhibitors.

Abstract
Serine/metallo-carbapenemase-coproducing pathogens, often referred to as "superbugs", are a significant clinical problem. They hydrolyze nearly all available β-lactam antibiotics, especially carbapenems considered as last-resort antibiotics, seriously endangering efficacious antibacterial treatment. Despite the continuous global spread of carbapenem resistance, no dual-action inhibitors are available in therapy. This Perspective is the first systematic investigation of all chemotypes, modes of inhibition, and crystal structures of dual serine/metallo-carbapenemase inhibitors. An overview of the key strategy for designing dual serine/metallo-carbapenemase inhibitors and their mechanism of action is provided, as guiding rules for the development of clinically available dual inhibitors, coadministrated with carbapenems, to overcome the carbapenem resistance issue.

Abstract
Continuing our research on the use of organophosphorus derivatives of aziridines in asymmetric synthesis and expanding the scope of their applicability, chiral aziridine-phosphines obtained earlier in our laboratory were used as chiral catalysts in the asymmetric Morita–Baylis–Hillman reaction of methyl vinyl ketone and methyl acrylate with various aromatic aldehydes. The desired chiral products were formed in moderate to high chemical yields and with enantiomeric excess reaching value of 98% ee in some cases. The use of catalysts being pairs of enantiomers led to the desired products with opposite absolute configurations.

Abstract
Metalloenzymes have critical roles in a wide range of biological processes and are directly involved in many human diseases; hence, they are considered as important targets for therapeutic intervention. The specific characteristics of metal ion(s)-containing active sites make exploitation of metal-binding pharmacophores (MBPs) critical to inhibitor development targeting metalloenzymes. This Perspective focuses on boron-containing MBPs, which display unique binding modes with metalloenzyme active sites, particularly via mimicking native substrates or tetrahedral transition states. The design concepts regarding boron-containing MBPs are highlighted through the case analyses on five distinct classes of clinically relevant nucleophilic metalloenzymes from medicinal chemistry perspectives. The challenges (e.g., selectivity) faced by some boron-containing MBPs and possible strategies (e.g., bioisosteres) for metalloenzyme inhibitor transformation are also discussed.

Abstract
The [2-formyl-4-(trifluoromethyl)phenyl]boronic acid as well as its benzoxaborole and bis(benzoxaborole) derivatives were obtained and their properties studied. The 2-formyl compound displays an unusual structure in the crystalline state, with a significant twist of the boronic group, whereas in DMSO solution it tautomerizes with formation of a cyclic isomer. All the studied compounds exhibit relatively high acidity as well as a reasonable antimicrobial activity. Docking studies showed interactions of all the investigated compounds with the binding pocket of Candida albicans LeuRS. High activity against Bacillus cereus was determined for the 2-formyl compound as well as for the novel bis(benzoxaborole), whereas the studied benzoxaborole shows high antifungal action with MIC values equal to 7.8and 3.9 μg/mL against C. albicans and A. niger respectively. None of the studied compounds exhibits reasonable activity against E. coli.

Vibrational Properties of Benzoxaboroles and Their Interactions with Candida albicans’ LeuRS. Symmetry (Basel) 2021.

Abstract
Benzoxaboroles have emerged over the past decade mainly due to their growing medicinal importance. Regarding the wide application of IR spectroscopy in the pharmaceutical industry, the vibrational properties of over a dozen of benzoxaboroles were described, based on results of DFT calculations as well as IR and Raman spectra measurements. Investigated series of compounds included the currently available antifungal drug (Tavaborole, AN2690) as well as its derivatives. An intense and well-isolated band corresponding to the B-OH group stretching vibrations was present in all experimental IR spectra in the range of 1446–1414 cm−1 and can be considered as characteristic for benzoxaboroles. The vibrational properties of benzoxaboroles are shown to be affected by the formation of intramolecular as well as intermolecular hydrogen bonds, which should also influence the interactions of benzoxaboroles with biomolecules and impact on their biological functions. Docking studies of the benzoxaboroles’ adenosine monophosphate (AMP) spiroboronates into the Candida albicans leucyl-RS synthetase binding pocket showed that the introduction of an amine substituent has a strong influence on their binding. The determined values of inhibition constants manifest high potential of some of the investigated molecules as possible inhibitors of that enzyme.
