title: HRE 664, a new parenteral penem. I. Antibacterial activity in vitro.
abstract: The new penem antibiotic HRE 664 displays potent antibacterial activity in vitro against a broad spectrum of clinically relevant bacterial strains including Gram-negative and Gram-positive aerobes and anaerobes. With an MIC 90% of 0.43 micrograms/ml, it is also active against methicillin-resistant staphylococci. HRE 664 is extremely stable against beta-lactamases, it binds preferentially to the penicillin-binding proteins 2, 3, 5 and 6 of Escherichia coli.
