    Cefonicid Sodium
    • Detailed Description

      CAS Number: 61270-78-8

      Molecular Formula: C18H16N6O8S3 • 2Na

      Molecular Weight: 586.53

      Mechanism of Action: Cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases.

      Storage Conditions: -20°C

      Tariff Code: 2941.90.3000

    • Applications

      Spectrum: Effective against Gram-positive and Gram-negative bacteria.

      Microbiology Applications: Cefonicid sodium is effective against E. coli, Klebsiella, Enterobacter, and Citrobacter.

      Eukaryotic Cell Culture Applications: The interaction of cefonicid (and other beta-lactams including cefazolin, cephalothin, ampicillin, and piperacillin) with the purified mitochondrial carnitine/acylcarnitine transporter reconstituted in liposomes has been studied. When added to the proteoliposome, cefonicid was found to competitively inhibit the carnitine/carnitine antiport catalysed by the reconstituted transporter. It was the most effective of the antibiotics tested with an IC50 of 0.12 mM after 60 h of incubation. (Pochini et al 2008)
