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.

| Description | 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. |
| In vitro | Pipequaline is extensively bound to plasma proteins: i.e. human serum albumin (HSA), alpha-1-acid glycoprotein (AAG), lipoproteins and blood cells, mainly erythrocytes[1]. |
| In vivo | Intravenously administered pipequaline exerts a partial suppression of activations by kainate, glutamate and acetylcholine. Microiontophoretic applications of pipequaline reduces the neuronal activation by kainate[2]. Pipequaline produces dose-related decreases in motor activity. Pipequaline produces significant dose-related decreases in the number of head-dips made[3]. |
| Animal Research | Rats: Pipequaline is dissolved in water to give injection volumes of 2 mL/kg. Rats are injected with 5, 10, and 50 mg/kg pipequaline. Infrared cells in the walls of the box provided automated measures of locomotor activity and rearing, respectively[3]. |
