Isolated from the stem of the fruiting bodies of the basidiomycete strain Laccaria amethystea, it exhibits inhibitory activity against proteases. It has a role as a metabolite and a protease inhibitor. It is a member of isochromenes, an organic heterotricyclic compound, a member of phenols, a member of orthoquinones, a cyclic acetal and an enol ether."}]
