  • Title: Synthesis and evaluation of a class of new coumarin triazole derivatives as potential antimicrobial agents.
    Author: Shi Y, Zhou CH.
    Journal: Bioorg Med Chem Lett; 2011 Feb 01; 21(3):956-60. PubMed ID: 21215620.
    Abstract:
    A series of new coumarin-based 1,2,4-triazole derivatives were designed, synthesized and evaluated for their antimicrobial activities in vitro against four Gram-positive bacteria (Staphylococcus aureus, MRSA, Bacillus subtilis and Micrococcus luteus), four Gram-negative bacteria (Escherichia coli, Proteus vulgaris, Salmonella typhi and Shigella dysenteriae) as well as three fungi (Candida albicans, Saccharomyces cerevisiae and Aspergillus fumigatus) by two-fold serial dilution technique. The bioactive assay showed that some synthesized coumarin triazoles displayed comparable or even better antibacterial and antifungal efficacy in comparison with reference drugs Enoxacin, Chloromycin and Fluconazole. Coumarin bis-triazole compounds exhibited stronger antibacterial and antifungal efficiency than their corresponding mono-triazole derivatives.
