The emerging of the New Delhi metallo-beta-lactamase (NDM-1) has become one of the greatest threats to the clinical treatment. Although the structure of NDM-1 has been determined by X-ray crystallography, the molecular mechanism and process of catalysis reaction remain elusive. NMR spectroscopy plays a unique role in the characterization of conformational dynamics. Here we report the backbone H, N and C chemical shift assignments of NDM-1 by heteronuclear multidimensional NMR spectroscopy as well as its secondary structure in solution as predicted by TALOS+.

The rapid and early detection of infections and antibiotic resistance markers is a critical challenge in healthcare. Currently, most commercial diagnostic tools for analyzing antimicrobial resistance patterns of pathogens require elaborate culture-based testing. Our study aims to develop a rapid, accurate molecular detection system that can be used directly from culture, thereby introducing molecular testing in conjunction with culture tests to reduce turnaround time and guide therapy.

Given the ever-evolving landscape of antimicrobial resistance, the emergence of New Delhi metallo-β-lactamase-1 (NDM-1) has introduced a formidable challenge to global public health. In previous research, we identified the Compound Zndm19 as an NDM-1 inhibitor and reported Zndm19 derivatives, which exhibited moderate antibacterial activity when combined with meropenem (MEM). This moderate activity may have been due to the inability of Zndm19 to efficiently penetrate the bacterial outer membrane or its susceptibility to hydrolysis, which prevented it from exerting strong enzyme inhibition in synergy with bacterial cells.

Unlabelled: Carbapenem-resistant spp. pose a significant challenge in clinical settings due to limited treatment options for nosocomial infections. Carbapenem-hydrolyzing class D beta-lactamases are the primary cause for carbapenem resistance, while metallo-beta-lactamases (MBLs) New Delhi metallo beta-lactamase (NDM) and imipenemase (IMP) also contribute.

Background and objectives Antimicrobial resistance (AMR) is a growing global threat, with carbapenemase-producing Enterobacterales (CPEs) representing a critical public health challenge. Rapid and accurate detection of CPEs is essential for controlling fatal bacterial AMR infections. This study evaluated the performance of MacConkey media supplemented with ertapenem (MacErt1 and MacErt2) for the detection of CPEs.
