A series of novel benzimidazole-derived chalcones containing the 1,3,4-oxadiazole moiety were synthesized and characterized by IR, 1H, 13C NMR, and mass spectra and elemental analysis. The synthesized compounds were evaluated for their efficiency as antibacterial agents against two Gram-positive and Gram-negative strains of bacteria along with antifungal activity against three fungal species. Antibacterial activity revealed that tested compounds exhibited potent activity whereas some compounds exhibited moderate antifungal activity as compared to the standards.
