of olympicin A prompted us to carry out the total synthesis of 6 and a series of analogues in order to assess their structure-activity profile as a new group of antibacterial agents. Following the synthesis of 6 and structurally-related acylphloroglucinols 7–15 and 18–24, their antibacterial activities against a panel of S. aureus strains were evaluated. The presence of an alkyloxy group consisting

Naturalproducts represent a rich source of antibiotics that address versatile cellular targets. The deconvolution of their targets via chemical proteomics is often challenged by the introduction of large photocrosslinkers. Here we applied elegaphenone, a largely uncharacterized naturalproductantibiotic bearing a native benzophenone core scaffold, for affinity‐based protein profiling (AfBPP) in Gram‐positive
