The molecule is an organic heterotetracyclic compound that is 4,4,6a,12b-tetramethyl-1,4a,5,6,6a,12,12a,12b-octahydro-2H,11H-benzo[f]pyrano[4,3-b]chromene-3,11(4H)-dione substituted at position 4a by a hydroxy and and at position 9 by 4-methoxyphenyl group (the 4aS,6aR,12aR,12bR stereoisomer). 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.
