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
合成了包含亲脂性C -7侧链和极性C -3硫代吡啶鎓基团的独特组合的头孢菌素衍生物,发现它们在体外和体内均显示出强大的抗-MRSA活性。利用的最佳C -7侧链是2,5-二氯苯基硫代乙酰胺基和2,6-二氯吡啶-4-基硫代乙酰胺基。所述Ç -3 thiopyridinium环在与氨基酸和丙酮酸基团被设计为赋予水溶解度按要求IV制剂氮所取代。本文描述了这些新型头孢菌素的特征,并着重介绍了开发的合成方法以允许其实用,大规模的合成。
