Coelomycin, a highly substituted 2,6-dioxo-pyrazine fungal metabolite antibacterial agent discovered by Staphylococcus aureus fitness test profiling

J Antibiot (Tokyo). 2010 Aug;63(8):512-8. doi: 10.1038/ja.2010.86. Epub 2010 Jul 28.


Bacterial resistance to antibiotics, particularly to multiple antibiotics, is becoming a cause for significant concern. The only really viable course of action to counter this is to discover new antibiotics with novel modes of action. We have recently implemented a new antisense-based chemical genetic screening technology to accomplish this goal. The discovery and antibacterial activity of coelomycin, a fully substituted 2,6-dioxo pyrazine, illustrates the application of the Staphylococcus aureus fitness test strategy to natural products discovery.
