Abstract

|
|
|
In order to evaluate the antimicrobial effect of 2,3-disubstituted-1,4-naphthalenedione derivatives, we synthesized several 2-chloro, 2-bromo and 2-hydroxy-3(substituted)-1, 4-naphthalene-diones (1-25). These derivatives were tested for antifugal and antibacterial activities, in vitro, against Candida albicans 10231 and local, Aspergillus niger KCTC 1231, Tricophyton mentagrophytes KCTC 6085, Baciilus subtilis ACTT 6633, Pseudomonas aeruginsa NCTC 10490, Staphylococcus aureus ATCC 6538P, Escherichia coli NIHJ. The MIC values were determined by the two-fold agar dilution/strea method. Among these derivatives, 4, 5 and 6 showed the potent antifungal activities. Also 5 and 6 had the antibacterial activities. 5 with (1,2,4-triazolyl)-amino moirty was the most effective in preventing the growth of fungi, such as Candida albicans, Aspergillus niger and Tricophyton mentagrophytes.
