    • The minimal inhibitory concentrations (MIC, μg/mL) were estimated by the disk diffusion method. The final concentration of all cultures in Mueller-Hinon agar (MHA) for bacteria was adjusted to 106 CFU/mL and used for inoculation in the MIC test. Serial dilutions of the test compounds (dissolved in DMSO) were prepared at concentrations of 0-2000 μg/mL. Each plate was inoculated with 0.1 mL of the prepared bacterial cultures. Similarly, each plate carried a blank disc, with solvent DMSO only in the center to serve as negative control. The inoculated plates were then incubated at 37 °C for 18-20 h. The minimal inhibitory concentration (MIC) was detected as the lowest concentration of drug in plate for which no visible growth took place by macroscopic evaluation. All determinations were performed in triplicate and confirmed by three separate experiments.

    • -1 MTT in PBS) was added and cells were incubated for a further 4 h. 200 μL of DMSO were added to each culture to dissolve the MTT crystals. The MTT-formazan product dissolved in DMSO was estimated by measuring absorbance at 570 nm with a micro plate reader. Then the inhibitory percentage of each compound at various concentrations was calculated, and the IC50 value was determined.
