nxl 104

Avibactam sodium (NXL-104) is a non-β-lactam β-lactamase inhibitor that inhibits TEM-1, P99, and KPC-2 β-lactamases (IC50=8/80/38 nM) covalently and reversibly. Avibactam sodium has antimicrobial activity and can be used to treat urinary tract infections.

Avibactam free acid is a potent β-lactamase inhibitor exhibiting covalent and reversible properties, capable of inhibiting TEM-1, P99, and CTX-M-15 at nanomolar concentrations. Avibactam free acid and Ceftazidime may be combined for treating urinary tract infections.

Avibactam sodium hydrate (NXL-104 hydrate) is a highly effective β-lactamase inhibitor that inhibits β-lactamases TEM-1 and CTX-M-15, as well as the carbapenemase produced by Klebsiella pneumoniae and carbapenem-resistant Enterobacteriaceae.

Avibactam sodium (NXL-104) dihydrate inhibits CTX-M-15 and β-lactamase TEM-1 with IC50 values of 5 nM and 8 nM, respectively, and is a reversible covalent inhibitor of non-β-lactam β-lactamase [1].
