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.

FPI-1523 sodium, a derivative of avibactam, is a potent β-lactamase inhibitor with Kd values of 4 nM and 34 nM for CTX-M-15 and OXA-48, respectively. It inhibited PBP2 with an IC50 of 3.2 μM and has a high level of antibacterial and considerable antimicrobial activity.

Avibactam (NXL-104) free acid is a covalent, reversible inhibitor of non-β-lactam β-lactamase, with IC50 values of 8 nM for β-lactamase TEM-1 and 5 nM for CTX-M-15.

FPI-1523, a derivative of Avibactam, is a potent inhibitor of β-lactamase enzymes with Kd values of 4 nM and 34 nM for CTX-M-15 and OXA-48, respectively. It also inhibits PBP2 with an IC50 of 3.2 μM and demonstrates significant antimicrobial activity.

ANT3310 is an inhibitor of broad-spectrum covalent Serine β-Lactamase with IC50s ranging from 1 nM to 175 nM for AmpC, CTX-M-15, TEM-1, OXA-48, OXA-23, and KPC-2. ANT3310 can be used in studies about bacterial infection.

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].

FPI-1465 is a dual inhibitor of serine-β-Lactamases and Penicillin-binding proteins (PBPs), demonstrating inhibition of PBP2 with an IC50 of 1.0 μg mL. Additionally, it exhibits activity against β-lactamase CTX-M-15 and OXA-48, with dissociation constants (Kd) of 0.011 μM and 5.3 μM, respectively [1].
