Abstract
|
|
|
|
In order to evaluate the antimicrobial effect of 2,3-substituted-1.4-naphthoquinone derivatives, we newly synthesized several 2-chloro, 2-bromo and 2-hydroxy-1, 4-naphthoquinones and subjected to antibacterial and antifungal activites, in vitro, against Escherichia coli NIHJ, Staphylococcus aureus ATCC6538p, Candida albicans 10231, Aspergillus niger 1231 and Tricophyton mentagrophytes 6085. Among these derivatives 3, 9, 18 and 23 showed the potent antibacterial activities. 18, 23 and 28 have the antifungal activities. However, these compounds have no significant hemolytic activity at concentrations higher than that required for showing the antibacterial and antifungal activities.
