Abstract A series of novel 1,2‐bissubstituted disulfanes bearing beta‐amino acid, dihydropyrimidine‐2,4‐(1 H ,3 H )‐dione, hydrazide, hydrazone and azole moieties were synthesized. The antibacterial activity was evaluated by determining minimum inhibition (by broth microdilution) and minimum bactericidal (by growth on agar) concentrations. The assessment revealed that MIC values for L. monocytogenes varied between 3.9 and 62.5 μg/mL as well as for S. aureus ranged between 7.8 and 250 μg/mL, with the exception of one compound with much weaker MIC of 500 μg/mL. The MBC values for L. monocytogenes have been found to be of 7.8–250 μg/mL, while S. aureus demonstrated the higher resistance and MBCs varied in the range of 7.8–500 μg/mL. The determined MBC/MIC ratios showed that eleven compounds were classified bactericidal agents for all tested bacteria.
