Compounds 1-8 and ketoconazole (positive control) were dissolved in methanol at different concentrations from 10 to 0.078 μg/mL by the continuous two-fold dilution methods. A 10 μL quantity of test solution was absorbed by a paper disc (5 mm diameter) and placed on the assay plates. After 12 h incubation, zones of inhibition (mm in diameter) were recorded. The minimum inhibitory concentrations (MICs) were defined as the lowest concentration at which no microbial growth could be observed. The MIC values of compounds 1-8 were 2.5, 2.5, 15.6, 10.6, 1.3, 5.0, 10.2, and 10.1 μM, respectively (ketoconazole with MIC value of 0.2 μM).
