Antimalarial Activity of Macrocyclic Trichothecenes Isolated from the Fungus Myrothecium verrucaria

Abstract
Bioassay-guided fractionation of an extract from the fungus Myrothecium verrucaria BCC 112 resulted in the first isolation of roridin E acetate (5) from nature together with four common macrocyclic trichothecene isomers (1−4). Trichothecenes 1−5, while known as mycotoxins, were evaluated for their high antimalarial activity.
