pbp2

PBP2 is a selective inducer of G-quadruplex structures from the unstructured single-stranded DNA conformations. PBP2 downregulates BCL-2 gene expression in cancer cells.

Zidebactam (WCK-5107) is an effective β-lactamase inhibitor. Zidebactam also is a penicillin-binding protein2 inhibitor (IC50: 0.26 μg mL).

Zidebactam sodium salt is a potent inhibitor of β-lactamase, and also is an inhibitor of penicillin-binding protein2 (PBP2)(IC50 of 0.26 μg mL).

Mecillinam (Hexacillin), an extended-spectrum penicillin antibiotic, is considered to be active against Gram-negative bacteria by binding specifically to penicillin-binding protein 2 (PBP2). It is used primarily to treat urinary tract infections and has also been used in the treatment of paratyphoid fever and typhoid.

WCK-5153 is an enhancer of β-Lactamase and an inhibitor of PBP2 with antimicrobial activities against Pseudomonas aeruginosa. WCK-5153 can be used in studies about the treatment of serious infections caused by highly drug-resistant Gram-negative pathogens.

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.

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.

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].
