Lenapenem is a carbapenem-class beta-lactam antibiotic intermediate/research compound. It is mainly used in pharmaceutical research, antibacterial activity studies, and as a reference material for the development and quality control of carbapenem antibiotics. It acts by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins (PBPs).
