Definition:A member of the class of fluoren-9-ones that is 9H-fluoren-9-one which is substituted by a 2-(diethylamino)ethoxy group at positions 2 and 7. It is an interferon inducer and a selective alpha7 nicotinic acetylcholine receptor (alpha7 nAChR) agonist. Its hydrochloride salt is used as an antiviral drug.
