产品描述 | Cefuroxime-d3is intended for use as an internal standard for the quantification of cefuroxime by GC- or LC-MS. Cefuroxime is a cephalosporin antibiotic with broad-spectrum activity against Gram-positive and Gram-negative bacteria includingS. pyogenes,S. pneumoniae,S. viridans,E. coli,P. mirabilis,H. influenzae, andN. gonorrhoeae(mean MICs = 0.005-8.2 μg/ml).1Like other cephalosporins, cefuroxime inhibits peptidoglycan crosslinking and bacterial cell wall synthesis.2It is resistant to hydrolysis by bacterial β-lactamases, increasing its efficacy against β-lactamase-producing Gram-negative bacteria.3Cefuroxime is protective against Gram-positive and Gram-negative infectionsin vivowith mean ED50values ranging from 2 to 35 and 1 to 55 mg/kg, in mice and rats, respectively.4Formulations containing cefuroxime have been used to treat urinary tract infections. 1.O'Callaghan, C.H., Sykes, R.B., Griffiths, A., et al.Cefuroxime, a new cephalosporin antibiotic: Activity in vitroAntimicrob.
