Abstract

Three previously undescribed highly modified lanostane triterpenoids, ganopyrone A, ganocolossusin I, and ganodermalactone Y, were isolated from the artificially cultivated fruiting bodies of the basidiomycete Ganoderma colossus TBRC-BCC 17711. Ganopyrone A possesses an unprecedented polycyclic carbon skeleton with an α-pyrone ring and C-18/C-23 bond. It showed antimalarial activity against Plasmodium falciparum K1 (multidrug-resistant strain) with an IC50 value of 7.8 μM (positive control: dihydroartemisinin, IC50 1.4 nM), while its cytotoxicity (Vero cells) was much weaker (IC50 103 μM).

Keywords: Antimalarial activity; Ganoderma colossus; Modified lanostanes; Mushroom cultivation.
