We report the discovery of a promising NDM-1 inhibitor, ebselen, through a cell-based screening approach. Enzymatic kinetic study and ESI-MS analysis suggested that ebselen could bind to NDM-1 by forming a S-Se bond with the Cys(221) residue at the active site, thereby exhibiting a new inhibition mechanism with broad spectrum inhibitory potential.
