Abstract
Novel 1,3,4-Oxadiazoles bearing benzimidazole nucleus were designed, synthesized using 2-(2-(substituted phenoxymethyl)-1H-benzo[d]imidazol-1-yl)acetohydrazide and carbon disulfide. These newly synthesized benzimidazolyl oxadiazoles along with benzimidazolyl acetates and benzimidazolyl acetohydrazides were screened for their antibacterial activity against two kinds of strains using the agar disk diffusion method and antifungal activity against Aspergillus niger and Ustilago maydis. The results showed that some of the compounds exhibited moderate activity against both the strains in antibacterial activity and majority of compounds are not active in antifungal activity. The structure-activity relationships were briefly discussed. The studies indicated that compounds of Benzimidazolyl acetohydrazide were the most potent inhibitors compared to the other compounds under investigation.
