Design and synthesis of 8-hydroxy-[1,6]naphthyridines as novel inhibitors of HIV-1 integrase in vitro and in infected cells

J Med Chem. 2003 Feb 13;46(4):453-6. doi: 10.1021/jm025553u.

Abstract

Naphthyridine 7 inhibits the strand transfer of the integration process catalyzed by integrase with an IC50 of 10 nM and inhibits 95% of the spread of HIV-1 infection in cell culture at 0.39 microM. It does not exhibit cytotoxicity in cell culture at < or =12.5 microM and shows a good pharmacokinetic profile when dosed orally to rats. The antiviral activity of 7 and its effect on integration were confirmed using viruses with specific integrase mutations.
