From Wikipedia, the free encyclopedia
A-412,997 is a drug which acts as a dopamine agonist that is used in scientific research. It is the first drug developed that is a highly selective agonist for the D4 subtype, with significantly improved selectivity over older D4-preferring compounds such as PD-168,077 and CP-226,269.[1] It is unclear what applications this drug might be used for, but in animal tests it induced penile erection and improved cognitive performance in rats.[2] Also unlike other dopamine agonists, selective D4 agonists do not cause side effects such as sedation and nausea, and so might have advantages over older dopamine agonist drugs.[3]
