Abstract

ABSTRACT In this paper, we describe our discovery of burnettiene A (1) as an antimalarial compound from the culture broth of Lecanicillium primulinum (current name: Flavocillium primulinum) FKI-6715 strain utilizing our original multidrug-sensitive yeast system. This polyene-decalin polyketide natural product was originally isolated as an antifungal active compound from Aspergillus burnettii. However, the antifungal activity of 1 has been revealed in only one fungal species, and the mechanism of action of 1 remains unknown. After the validation of mitochondrial function inhibitory of 1, we envisioned a new antimalarial drug discovery platform based on mitochondrial function inhibitory activity. We evaluated antimalarial activity and 1 showed antimalarial activity against Plasmodium falciparum FCR3 (chloroquine sensitive) and the K1 strain (chloroquine resistant). Our study revealed the utility of our original screening system based on a multidrug-sensitive yeast and mitochondrial function inhibitory activity for the discovery of new antimalarial drug candidates.
