Abstract

A series of 6-[N-(halophenyl)amino]-7-chloro-5, 8-quinolinedione derivatives 1-10 were tested for antifungal susceptibilities, in vitro, aginst pathogenic Candida species such as C. ablbicans, C glabrata, C. krusei, C. parapsilosis and C. tropicalis. The MICs were determined by the standard macrodilution techniques, according to the NCCLS 1992 guidelines. The 6-[N-(halo-standard macrodilution techniques, according to the NCCLS 1992 gidelines. The 6-[N-(halo-phenyl)amino]-7-chloro-5, 8-quinolinedione derivatives showed generally potent antifungal activities against pathogenic Candida species. Among them, derivative 1, 2, 5, and 7 showed more potent antifungal activities than kietoconazole. All derivatives 1-10 had specially potent activities against C. torpicalis. Derivative 1 and 2 containing 9N-3, 4-dihalo-phenyl)amino moiety exhibited the potent antifugal activities. Derivative 2 with (3, 4-dichlorophenyl)amino substitutent was the most effetive in preventing the growth of Candida species at MICs 4.mu.g/ml respectively.
