It is a sesquiterpenoid isolated from the fungus Aspergillus aculeatus. It has a role as an Aspergillus metabolite. It is a sesquiterpenoid, a carbobicyclic compound, a L-proline derivative and a carboxylic ester. It is functionally related to an aculene D. It is a conjugate base of an aculene B(1+)."}]
