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

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.

Synthesis and biological evaluation of benzo[b]naphthyridones, a series of new topical antibacterial agents.

We describe here the synthesis and biological evaluation of a series of benzo[b]naphthyridones, a new family of tricyclic antibacterial compounds that have a gram-positive spectrum of activity. RP60556A, one of the most potent of these compounds, is bactericidal against multiresistant cocci, especially multiresistant Staphylococcus aureus strains. Its physico-chemical and biological properties make it particularly suitable for topical antibacterial use.
