    Ceftibuten

    1,482,390.00Rp - 11,294,400.00Rp

    Ceftibuten is a third generation cephalosporin antibiotic.  It has exceptional β-lactamase stability and is resistant to inactivation by most β-lactamases made by common Gram-negative and Gram-positive bacteria.  Ceftibuten can be used to study drug resistance and transport pathways.  Ceftibuten is freely soluble in aqueous solution and DMSO.

    Mechanism of Action Like β-lactams, 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.
    Spectrum Ceftibuten is a broad-spectrum antibiotic targeting a wide variety of Gram-positive and Gram-negative bacteria.
    Microbiology Applications

    Ceftibuten is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive and Gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options.

    Representative MIC values include:

    • Haemophilus influenzae 0.015 µg/mL – 1 µg/mL
    • Escherichia coli 0.015 µg/mL - 8 µg/mL

    Eukaryotic Cell Culture Applications Ceftibuten uptake in human intestinal epithelial cells (Caco‐2) cells growing on transwells was studied, and authors found that uptake involves multiple transport pathways. Since cells are polarized, with an apical end and a basolateral end, the apical transport system was found to be different. Apical uptake is mediated by an energy-dependent carrier and energy-independent facilitated diffusion (Menon and Barr 2002).
