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-naphthalenediones (1–25). These derivatives were tested for antifungal and antibacterial activities,in vitro, againstCandida albicans 10231 and local,Aspergillus niger KCTC 1231,Tricophyton mentagrophytes KCTC 6085,Bacillus subtilis ATCC 6633,Pseudomonas aeruginosa NCTC 10490,Staphylococcus aureus ATCC 6538p,Escherichia coli NIHJ. The MIC values were determined by the two-fold agar dilution/streak 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 moiety was the most effective in preventing the growth of fungi, such asCandida albicans, Aspergillus niger andTricophyton mentagrophytes.
