What is "enpiprazole"

n. A phenylpiperazine tranquilizer.

Enpiprazole ( INN, BAN) is an anxiolytic drug of the phenylpiperazine group that was never marketed. It produces anxiolytic-like effects in animals, though these effects appear to be biphasic and may reverse at high doses. It is known to produce ortho-chlorophenylpiperazine (o-cPP) as a metabolite.
