5,8-Quinazolinediones modified at positions 6 and 7 were synthesized and tested for in vitro antifungal activities against Candida species and Aspergillus niger. Most of 5,8-quinazolinediones 3-5 generally exhibited potent antifungal activity. 6-Arylamino-7-chloro-5,8-quinazolinediones (3) generally showed more potent antifungal activity than 7-arylthio-5,8-quinzolinediones (4) and 6,7-bis-(arylthio)-5,8-quinazolinediones (5).
