cefazolin

Cefazolin is a semi-synthetic cephalosporin that has a broad spectrum of antibacterial activity and inhibits the synthesis of bacterial cell walls.

Cefazolin sodium (cephazolin sodium) salt binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Cefazolin sodium salt is the sodium salt of cefazolin, a beta-lactam antibiotic and first-generation cephalosporin with bactericidal activity. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity, which results in the weakening of the bacterial cell wall and cell lysis.

Cefazolin-13C2,15N is intended for use as an internal standard for the quantification of cefazolin by GC- or LC-MS. Cefazolin is a broad-spectrum cephalosporin antibiotic that is active in vitro against various Gram-positive and Gram-negative bacteria (MICs = 0.2-12.5 μg/ml). It also inhibits the growth of clinical isolates of S. aureus, E. coli, P. mirabilis, and K. pneumoniae (MICs = 0.1-25 μg/ml). In vivo, cefazolin protects against S. aureus, E. coli, and P. mirabilis infection in mice (ED50s = <0.09-1.78, 0.44-3.63, and 2.31-5.2 mg/animal, respectively). Formulations containing cefazolin have been used to treat a variety of bacterial infections.

Cefazolin sodium pentahydrate, a first-generation cephalosporin antibiotic, is employed in diverse bacterial infection research [1] and exhibits an anti-inflammatory effect capable of attenuating post-operative cognitive dysfunction (POCD) [2].

Cefazolin sodium (Standard) is the standard substance of Cefazolin sodium, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Cefazolin sodium (cephazolin sodium) salt binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Cefazolin sodium salt is the sodium salt of cefazolin, a beta-lactam antibiotic and first-generation cephalosporin with bactericidal activity. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity, which results in the weakening of the bacterial cell wall and cell lysis.

Cefsulodin is a β-lactam antibiotic that lyses actively-growingE. coliby binding specifically to the intermembrane proteins, penicillin-binding proteins 1a and b, whose transglycosylase and transpeptidase activities are involved in cell elongation and septation.1Cefsulodin has been used in combination with other β-lactam antibiotics, such as cefazolin as a strategy to circumvent drug resistance.2

7-ZACA (cefazolin decarboxylated) is a decarboxylated derivative of cefazolin, suitable for biochemical experiments and drug synthesis research.
