Pipequaline hydrochloride

Pipequaline hydrochloride (PK-8165 hydrochloride) is an anticonflict and anticonvulsant quinoline derivative and an anxiolytic drug that was never marketed. It possesses a novel chemical structure, not closely related to other drugs of this type, with a pharmacological profile similar to benzodiazepines but predominantly anxiolytic, exhibiting minimal sedative, amnestic, or anticonvulsant effects, thus classified as a nonbenzodiazepine anxiolytic.
