Abstract

We report a promising NDM-1 inhibitor, disulfiram, which can covalently bind to NDM-1 by forming an S-S bond with the Cys208 residue. Its copper-containing metabolite in vivo, Cu(DTC)2, also inactivated NDM-1 through oxidizing the Zn(ii) thiolate site of the enzyme, therefore exhibiting dual functional inhibitory potential against B1 and B2 subclass MβLs.
