  Synthesis and structure-activity relationship of C-3 benzoyloxymethyl cephalosporins exhibiting anti-MRSA activities

  摘要：

  A series of cephalosporins bearing C-3 benzoyloxymethyl groups were prepared and evaluated for their anti-MRSA activity and plasma stability. They exhibit excellent in vitro activity (MIC = 0.06 similar to 2 mu g/mL) against MRSA and excellent stability in human plasma. (C) 1997 Elsevier Science Ltd.

Less than 500 fM of β-lactamase in cell lysates can be readily detected, and β-lactamase expression in living cells can be imaged with a red fluorescence derivative. These new fluorogenic substrates should find uses in clinical diagnostics

  Cephalosporin derivatives containing a unique combination of lipophilic C-7 sidechains and polar C-3 thiopyridinium groups were synthesized and found to exhibit potent anti-MRSA activity in vitro and in vivo. The optimum C-7 sidechains utilized were 2,5-dichlorophenylthioacetamido and 2,6-dichloropyrid-4-ylthioacetamido. The C-3 thiopyridinium rings were substituted at nitrogen with amino acid and
