Abstract

A novel series of 3,5-disubstituted isoxazoles bearing kojic acid moiety were synthesized via Cu(I)-catalyzed 1,3-dipolar cycloaddition reaction of terminal alkynes with nitrile oxide formed in situ from the corresponding hydroximoyl chloride. Structures of the synthesized compounds were characterized using spectroscopic analysis data. Antimicrobial activity of the isoxazole conjugates was determined as MIC values by broth microdilution method against different bacteria: Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Salmonella typhi, and fungi Candida kefyr. The obtained results revealed notable antibacterial and antifungal activities of the compounds.
