Isolated from the culture broth of Penicillium, it acts as a selective inhibitor of acetylcholinesterase. It has a role as an antimicrobial agent, an EC 3.1.1.7 (acetylcholinesterase) inhibitor and a Penicillium metabolite. It is an organic heterotetracyclic compound, a tertiary alcohol, a cyclic ketone, an aromatic ether and a delta-lactone."}]
