Abstract

The antifungal activity of a library of 32 cyclitols and derivatives, including 6 previously unreported cyclitol amino acid conjugates, was studied against the clinically important yeasts Candida albicans, Candida tropicalis and Cryptococcus neoformans along with Saccharomyces cerevisiae. Bioautography followed by standardized microbroth dilution methods were used and allowed to identify an azidoinositol glycoside (11) and an azidoconduritol linked to an aromatic aldehyde (18) as promising compounds. The results suggest the relevance of exploring synthetic cyclitolic structures as potential antifungal leaders.
