Liquid drug assays of the 12 3,4-dihydroisocoumarins and S. cerevisiae strains expressing Pdr5 WT or the mutant Pdr5 EQ. (A) The influence of 14, (R)-19, (S)-19, 3, 4, 21, and 16 on growth of strains expressing Pdr5 WT. (B) The influence of 14, (R)-19, (S)-19, 3, 4, 21, and 16 on growth of strains expressing Pdr5 EQ. (C) The influence of (R)-19a, (S)-19a, 16a and ellagic acid on growth of strains expressing Pdr5 WT. (D) The influence of (R)-19a, (S)-19a, 16a and ellagic acid on growth of strains expressing Pdr5 EQ. Cells were incubated at different concentrations of the compounds for 48 h at 30 °C and OD600 was determined.
