Monobactam

Aztreonam. (The four-membered ring at the bottom is the β-lactam. There is a second thiazole ring, but it is not fused to the β-lactam ring.)

Monobactams are β-lactam compounds wherein the β-lactam ring is alone and not fused to another ring, in contrast to most other β-lactams. They are effective only against aerobic Gram-negative bacteria (e.g., Neisseria, Pseudomonas).

The only commercially available monobactam antibiotic is aztreonam.
