Structures and colistin MICs of the most effective compounds in colistin-susceptible strains of A. baumannii and K. pneumoniae. All compounds were located on plate 13160331. Dianemycin lowered the colistin MIC 16-fold in both AB5075 and KP2146, from 1 μg/mL to 0.0625 μg/mL. Scopafungin and variabiline monohydrochloride had the same activity in KP2146. Natural products were tested at 20 μM. Fold change as compared to the control antibiotic MIC is expressed in parentheses. * indicates the lowest antibiotic concentration tested.
