Biological activities of compounds 1–12.

^aMIC₉₀ represents the minimal inhibitory concentration of tested compounds that prevent 90% of E. coli BW25113 growth as measured by resazurin reduction.

^bEC₉₀ represents the effective concentration of tested compounds that prevents the growth of E. coli BW25113 in the presence of 8 µg/mL pyridomycin as measured by resazurin reduction (the MIC₉₀ of pyridomycin alone is 12.5–25 µg/mL). Data are the result of at least two biological replicates and are presented as mean values ± SEM. Source data are provided as a Source Data file.
