development of antibacterial agents with new chemical scaffolds and mechanisms of action. We present the first structure–activity relationship (SAR) study of 16 derivatives of a structurally novel antibiotic merochlorin A that were designed using a biosynthetic blueprint. Our lead compounds are active against several Gram‐positive bacteria such as Staphylococcus aureus (SA), methicillin‐resistant Staphylococcus
