    • 5 CFUs/mL of fungi were prepared from broth cultures in log phase growth. Fungal plates were made in triplicate and incubated at 30 °C for about 24-48 h for yeast, about 72 h for moulds, and about 168 h for dermatophytes. The MIC was defined as the lowest concentration of the test compound, which resulted in no visible growth on the plate.

    • Bacterial growth inhibition assay (disk diffusion method). Growth inhibition was performed by the filter paper disk diffusion method on Mueller-Hinton agar with 7% of defibrinated horse blood under microaerophilic conditions at 37 °C. The samples were tested using different amounts. A sample in 40 μL of methanol was applied by a microsyringe to the paper disks (6 mm diameter). After drying in a fume hood, the disks were placed on the agar surface that was inoculated with Helicobacter pylori. Following incubation for 3-5 days at 37 °C, the inhibition zone around each disk (average diameter) if any, was recorded. All tests were performed in triplicate and the antibacterial activity was expressed as the mean of inhibition diameters (mm) produced by title compounds.
