Resistance
to β-lactam antibiotics can be mediated by metallo-β-lactamase
enzymes (MBLs). An MBL inhibitor could restore the effectiveness of
β-lactams. We report on the evaluation of approved thiol-containing
drugs as inhibitors of NDM-1, VIM-1, and IMP-7. Drugs were assessed
by a novel assay using a purchasable fluorescent substrate and thermal
shift. Best compounds were tested in antimicrobial susceptibility
assay. Using these orthogonal screening methods, we identified drugs
that restored the activity of imipenem.
