Department of Pathology, Hershey Medical Center, Hershey, Pennsylvania, USA.

Faropenem demonstrated low MICs (< or = 1 microg/ml) for all penicillin-susceptible and nonsusceptible pneumococci and exhibited very strong abilities to bind to Streptococcus pneumoniae penicillin-binding proteins (PBPs), except for PBP2X. The lower faropenem affinity for PBP2X did not affect MICs for any strains tested, and only imipenem had lower MICs, with much lower binding affinities for all PBPs tested, than faropenem.

D047090	beta-Lactams	Four-membered cyclic AMIDES, best known for the PENICILLINS based on a bicyclo-thiazolidine, as well as the CEPHALOSPORINS based on a bicyclo-thiazine, and including monocyclic MONOBACTAMS. The BETA-LACTAMASES hydrolyze the beta lactam ring, accounting for BETA-LACTAM RESISTANCE of infective bacteria.	beta-Lactam,4-Thia-1-Azabicyclo(3.2.0)Heptanes,4-Thia-1-Azabicyclo(4.2.0)Octanes,beta Lactam,beta Lactams
