  Benzo[f]naphtyridones: a new family of topical antibacterial agents active on multi-resistant Gram-positive pathogens

  摘要：

  The synthesis and antibacterial activity of benzo[f][1,7]naphtyridone derivatives are reported. These compounds are potent antibacterial agents with a Gram-positive spectrum of activity. They are active against multi-resistant cocci, especially Staphylococcus aureus strains. Their physico-chemical and biological properties make them particularly suitable for topical antibacterial use. (C) 2003 Elsevier Science Ltd. All rights reserved.
