Table 6. Activity of Analogues in Other P. aeruginosa Strains and Toxicity Counter Screen.

^aAverage of at least three replicates ± standard deviation.

^b405 nm wavelength measuring effect on pyoverdine production.

^cMeasurement taken as AbsAC_–35 (absolute active concentration at 35% inhibition), the predetermined activity threshold chosen for comparison because not all compounds reached a plateau of activity at 50% inhibition.

^dQuantified by analysis of the isolated pyoverdine HPLC peaks present in culture media of cells treated with varying concentrations of each inhibitor.
