Inhibitory effects and mechanism of antifungal action of the natural cyclic depsipeptide, aureobasidin A against Cryptococcus neoformans

Cryptococcosis is an opportunistic fungal infection caused mainly by Cryptococcus neoformans. The aim of the present study was to evaluate the inhibitory effect of aureobasidin A on C. neoformans with special focus on its mode of action. The effect of aureobasidin A on cell membrane ergosterol content, cell wall permeability, membrane pumps activities, the total oxidant status (TOS) and melanin production was evaluated. Cytotoxicity and cell...
