Reported herein is a fluorescence assay for the rapid screening of metallo-β-lactamase (MBL) inhibitors. This assay employs a fluorogenic carbapenem CPC-1 as substrate and is compatible with all MBLs, including B1, B2 and B3 subclass MBLs. The efficiency of this assay was demonstrated by the rapid inhibition screening of a number of molecules against B2 MBL CphA and 2,3-dimercaprol was identified as a potent CphA inhibitor.
