Isolated from Strongylophora hartmani, it exhibits activity against the influenza virus. It has a role as a metabolite, an antineoplastic agent and an EC 3.2.1.18 (exo-alpha-sialidase) inhibitor. It is a member of phenols, an aromatic ether, a sesquiterpenoid and an organic heterotetracyclic compound."}]
