Tigemonam<unk> s are monocyclic and bacterially-produced β-lactam antibiotics. The β-lactam ring is not fused to another ring, in contrast to most other β-lactams.<unk> s are effective only against aerobic Gram-negative bacteria (e.g., Neisseria, Pseudomonas). Siderophore-conjugated<unk> s show promise for the treatment of multi drug-resistant pathogens. Aztreonam is a commercially available<unk>  antibiotic. Other examples of<unk> s are tigemonam, nocardicin A, and tabtoxin. Adverse effects to<unk> s can include skin rash and occasional abnormal liver functions.<unk>  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.<unk> s can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
