  • Published : 2002.12.01

Abstract

6,7-Bis-[S-(aryl)thio]-5,8-quinolinediones 4 and 5 were synthesized by the substitution of 6,7-dichloro-5,8-quinolinediones with appropriate arylthiols. Their antifungal activity were tested in vitro for their growth inhibitory activities against pathogenic fungi in comparison with flucytosine. The antifungal activities were significantly improved by S-(aryl)thio moieties of the compounds 4 and 5. The all tested compounds 4 and 5 showed generally good activities against C. albicans and A. niger ranging from 0.8 to 25 $\mu\textrm{g}$/ml. Among them, compounds 4d-4h and 5a-5c exhibited also good activities against C. krusei and C. tropicalis. The activities of compounds 4j and 4I were comparable to those of flucytosine against all tested fungi.
