Abstact

The bridged monobactam β-lactamase inhibitor MK-8712 (1) effectively inhibits class C β-lactamases. Side chain N-alkylated and ring-opened analogs of 1 were prepared and evaluated for combination with imipenem to overcome class C β-lactamase mediated resistance. Although some analogs were more potent inhibitors of AmpC, none exhibited better synergy with imipenem than 1.
