A library of 53 benzimidazole derivatives, with substituents at positions 1, 2 and 5, were synthesized and screened against a series of reference strains of bacteria and fungi of medical relevance. The SAR analyses of the most promising results showed that the antimicrobial activity of the compounds depended on the substituents attached to the bicyclic heterocycle. In particular, some compounds displayed antibacterial activity against two methicillin-resistant Staphylococcus aureus (MRSA) strains with minimum inhibitory concentrations (MICs) comparable to the widely-used drug ciprofloxacin. The compounds have some common features; three possess 5-halo substituents; two are derivatives of (S)-2-ethanaminebenzimidazole; and the others are derivatives of one 2-(chloromethyl)-1Hbenzo[ d]imidazole and (1H-benzo[d]imidazol-2-yl)methanethiol. The results from the antifungal screening were also very interesting: 23 compounds exhibited potent fungicidal activity against the selected fungal strains. They displayed equivalent or greater potency in their MIC values than amphotericin B. The 5-halobenzimidazole derivatives could be considered promising broad-spectrum antimicrobial candidates that deserve further study for potential therapeutic applications.

A novel curcumin mimic library (14a-14h and 15a-15h) possessing variously substituted benzimidazole groups was synthesized through the aldol reaction of (E)-4-(4-hydroxy-3-methoxyphenyl)but-3-en-2-one (7) or (E)-4-(3-hydroxy-4- methoxyphenyl)but-3-en-2-one (13) with diversely substituted benzimidazolyl-2-carbaldehyde (12a-12h). The MTT assay of the cancer cells MCF-7, SH-SY5Y, HEP-G2, and H460 showed that compound 14c with IC50 of 1.0 and 1.9 μM has a strong inhibitory effect on the growth of SH-SY5Y and Hep-G2 cells, respectively, and that compound 15h with IC50 of 1.9 μM has a strong inhibitory effect on the growth of MCF-7 cancer cells.
