A series of polyhalo isophthalonitrile derivatives (3 and 4) that incorporate a variety of substituents at the 2-, 4-, 5- and/or 6-positions of the isophthalonitrile moieties have been designed and synthesized. These derivatives were evaluated for their antimicrobial activity against Staphylococcus aureus, Bacillus cereus (Gram-positive bacteria), Escherichia coli, Pseudomonas aeruginosa (Gram-negative bacteria); and Candida albicans (Fungi). Compounds 3 and 4 showed stronger inhibition of Gram-positive bacteria and fungi growth, and the antimicrobial ability of compound 3j (a 4-(benzylamino)-5-chloro-2,6-difluoro analog, MIC[SA] = 0.5 μg/mL; MIC[BC] = 0.4 μg/mL; MIC[CA] = 0.5 μg/mL) were close to nofloxacin and fluconazole and identified as the most potent antimicrobial agents in the series. The preliminary analysis of structure-activity relationships is also discussed.
