Comment: Aztreonam is a monocyclic β-lactam antibiotic that is resistant to β-lactamase hydrolysis. It was isolated from Chromobacterium violaceum. Functionally it preferentially binds to and inactivates penicillin-binding protein-3 (PBP-3) and thereby inhibits bacterial cell wall synthesis. Aztreonam was removed from the World Health Organization's List of Essential Medicines in 2019.
