KPC-2-IN-2 (Compound 6c) is a potent Klebsiella pneumoniae carbapenemase (KPC-2) inhibitor with a Ki of 0.038 μM and can enhance the activity of cefotaxime in E. coli expressing KPC-2 [1].

KPC-2-IN-1, a boronic acid derivative, serves as an effective KPC-2 inhibitor with a K i of 0.032 μM, augmenting cefotaxime's efficacy against KPC-2 expressing E. coli. It demonstrates good tolerance in human HEK-293 cells, rendering it valuable for researching E. coli's resistance to β-lactam antibiotics [1] [2].

Durlobactam sodium salt (ETX2514) is a beta-lactamase inhibitor with IC50 values of 4 nM, 14 nM and 190 nM against class A KPC-2, class C AmpC and class D OXA-24.

Avibactam Tetrabutylammonium is the salt form of Avibactam.Avibactam is a non-β-lactam β-lactamase inhibitor that inhibits TEM-1, P99, and KPC-2 β-lactamases (IC50=8 80 38 nM) with covalent and reversible and can be used to treat urinary tract infections.

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.

KPC-IN-1 (compound 1e) is an inhibitor of Klebsiella pneumoniae carbapenemase KPC-2, with an IC50 value of 8.3 nM. KPC is a β-lactamase expressed in Gram-negative bacteria that hydrolyzes carbapenems, leading to significant bacterial resistance to carbapenem antibiotics.

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 salt-13C5 is the 13C labeled compound of Avibactam sodium salt. Avibactam sodium salt has a CAS number of 1192491-61-4. Avibactam is a reversible β-lactamase inhibitor (IC50: 8 80 38 nM, for TEM-1 P99 KPC-2 β-lactamases).
