In vitro activity of N-formimidoyl thienamycin (MK0787)

Abstract

The in vitro activity of N-formimidoyl thienamycin (MK0787), a stable congener of thienamycin, was determined against 200 species of aerobic and 84 species of anaerobic bacteria. The compound was highly active against resistant gram-negative bacilli, penicillin-resistant Staphylococcus aureus, enterococci, and anaerobic bacteria. The new derivative of thienamycin was more active than the parent compound, probably reflecting the stability of the analog.
