Hyalodendrin: a new fungitoxic epidithiodioxopiperazine produced by a Hyalodendron species

Abstract
A new fungitoxic metabolite, designated hyalodendrin, isolated from a culture medium which had supported growth of Hyalodendron sp., an imperfect fungus, was identified as 3-benzyl-6-hydroxymethyl-1,4-dimethyl-3,6-epidithiopiperazine-2,5-dione on the basis of spectrometric and chemical investigations.
