Effect of N-formimidoyl thienamycin (MK0787) on beta-lactamases and activity against beta-lactamase-producing strains

Abstract
N-Formimidoyl thienamycin (MK0787) was active against beta-lactamase-producing strains and was an effective inhibitor of beta-lactamases extracted and purified from these strains except for plasmid-mediated penicillinase type IV.
