We report how application of in silico fragment-based molecular design employing thiol-mediated metal anchorage leads to potent MBL inhibitors. The new inhibitors manifest potent inhibition of clinically important B1 subfamily MBLs, including the widespread NDM-1, IMP-1, and VIM-2 enzymes; with lower potency, some of them also inhibit clinically relevant Class A and D serine-beta-lactamases. The inhibitors show selectivity for bacterial MBL enzymes compared to that for human MBL fold nucleases. Cocrystallization of one inhibitor, which shows potentiation of Meropenem activity against MBL-expressing Enterobacteriaceae, with VIM-2 reveals an unexpected binding mode, involving interactions with residues from conserved active site bordering loops.
