Monobactams are bacterially-produced monocyclic β-lactam antibiotics. The β-lactam ring is not fused to another ring, in contrast to most other β-lactams.[1]
Monobactams are narrow-spectrum antibiotics effective only against aerobic Gram-negative[2] bacilli.[3][4] Due to their narrow spectrum, monobactams can be used to treat infections by susceptible bacteria without disrupting the patient's microbiota. Monobactams are neverthless seldom used.[2]
Aztreonam is the principal[3] and sole commercially available member of monobactams.[5] Other monobactams include tigemonam,[6] nocardicin A, and tabtoxin.
Pharmacology
Monobactams exert their antibacterial effects by binding to penicillin-binding proteins, thereby inhibiting bacterial wall synthesis. Monobactams are synergetic with aminoglycosides, andpiperacillin.[4]
Bacterial resistance to monobactams have been observed, and is mediated by bacterial betalactamases.[4]
Adverse effects
Adverse effects to monobactams can include skin rash and occasional abnormal liver functions.
Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam.[7] Monobactams can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
Research
Siderophore-conjugated monobactams show promise for the treatment of multi drug-resistant pathogens.[8]
