The molecule is an ergostanoid that is (22E)-ergosta-7,22-diene substituted by hydroxy groups at positions 3, 5 and 9 and an oxo group at position 6 (the 3beta,5alpha stereoisomer). It has been isolated from Aspergillus ochraceus. It has a role as an Aspergillus metabolite. It is a 3beta-hydroxy steroid, a 5alpha-hydroxy steroid, a 9-hydroxy steroid, a 6-oxo steroid, an ergostanoid and a tertiary alpha-hydroxy ketone.
