Abstract
2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones and 2H-[1,2,3]triazolo[4,5-g]quinoline-4,9-diones were synthesized and tested for in vitro antifungal activity against pathogenic fungi. Many of those synthesized showed potent antifungal activity. Compounds 3a, 3b, 3g, and 3h completely inhibited the growth of all fungal species tested at the MIC level of 0.8–12.5 µg/mL. The results suggest that 2H-[1,2,3]triazolo[4,5-g]isoquinoline-4,9-diones could be antifungal agents.
