The emerging NDM carbapenemases

open access: yesTrends in Microbiology, 2011
Carbapenems were the last β-lactams retaining near-universal anti-Gram-negative activity, but carbapenemases are spreading, conferring resistance. New Delhi metallo-β-lactamase (NDM) enzymes are the latest carbapenemases to be recognized and since 2008 have been reported worldwide, mostly in bacteria from patients epidemiologically linked to the Indian

Prevalence and molecular characterisation of New Delhi metallo-β-lactamases NDM-1, NDM-5, NDM-6 and NDM-7 in multidrug-resistant Enterobacteriaceae from India

International Journal of Antimicrobial Agents, 2014
The growing prevalence of carbapenem resistance in Enterobacteriaceae worldwide is a major concern. New Delhi metallo-β-lactamase (NDM)-mediated carbapenem resistance has been identified in Enterobacteriaceae from numerous countries including those of the Indian subcontinent. Currently, seven NDM β-lactamase variants (NDM-1 to -7) have been identified.

Simplified captopril analogues as NDM-1 inhibitors

Bioorganic and Medicinal Chemistry Letters, 2014
Captopril is a New Delhi metallo-β-lactamase-1 (NDM-1) inhibitor with an IC50 value of 7.9μM. It is composed of two units: a 3-mercapto-2-methylpropanoyl fragment and a proline residue. In this study, we synthesized simple amide derivatives of 3-mercapto-2-methylpropanoic acid, and then tested them as NDM-1 inhibitors in order to identify the ...

The spread and acquisition of NDM-1: a multifactorial problem

open access: yesExpert Review of Anti-infective Therapy, 2013
bla NDM is a major mechanism of resistance of Gram-negative bacteria to β-lactam antibiotics including the carbapenems. bla NDM has been acquired by a large range of Gram-negative bacilli, especially by the Enterobacteriaceae and Acinetobacter spp. The combination of human factors (suboptimal antibiotic stewardship and infection control, movement of ...

Dissemination of NDM-1

The Lancet Infectious Diseases, 2012
The dissemination of members of the Enterobacteriaceae family with extended spectrum beta-lactamases (ESBLs) and metallo-beta-lactamases (MBLs) has become a global concern. ESBLs and MBLs have been reported in humans, domestic animals, wildlife and the environment, and their isolation frequencies are increasing rapidly worldwide. Most studies have been

The directed evolution of NDM-1

Antimicrobial Agents and Chemotherapy, 2023
ABSTRACT β-Lactam antibiotics are among the most frequently prescribed therapeutic agents. A common mechanism of resistance toward β-lactam antibiotics is the production of β-lactamases. These enzymes are capable of hydrolyzing the β-lactam bond, rendering the drug inactive.

Specific NDM-1 Inhibitor of Isoliquiritin Enhances the Activity of Meropenem against NDM-1-positive Enterobacteriaceae in vitro

open access: yesInternational Journal of Environmental Research and Public Health, 2020
NDM-1-positive Enterobacteriaceae have caused serious clinical infections, with high mortality rates. Carbapenem was the ultimate expectation for the treatment of such infections in clinical practice.
