Bacterial FAS provides essential fatty acids for use in the assembly of key cellular components. Among them, FabI is an enoyl-ACP reductase which catalyzes the final and rate-limiting step of bacterial FAS. It is a potential target for selective antibacterial action, because it shows low overall sequence homology with mammalian enzymes. Until today, various compounds have been reported as inhibitors of bacterial FabI-inhibitory compounds. To discover novel small-molecular FabI inhibitors, we initially screened our compound library for inhibitory activity toward FabI of Escherichia coli. And discovered 4-pyridone derivatives as a lead compound. Structure optimization studies yielded 4-pyridone derivatives 7n having strong FabI-inhibitory and antibacterial activities against Staphylococcus aureus. There have been no reports concerning 4-pyridone derivatives as FabI inhibitor.

Novel 2,3-disubstituted 4-pyridone derivatives were prepared from 4-methoxypyridine through aldol condensation and isomerization of exo-olefin as key reactions, in fairly good to high yields. Copyright
