title: Effects of HR-592, a new derivative of indole, on conditioned behavior.
abstract: Effects of HR-592, a new derivative of indole, on conditioned avoidance and intracranial self-stimulation behavior were investigated in rats using a shuttle box and a Skinner box, respectively. The oral administration of HR-592 at doses of 3-10 mg/kg caused a dose-dependent suppression of the conditioned avoidance response. Even the escape response was slightly suppressed in the group administered 10 mg/kg of HR-592. The self-stimulation behavior was suppressed dose-dependently from 1 to 8 h after the administration of 6-10 mg/kg of HR-592. These results indicate that the action of HR-592 on conditioned avoidance response and intracranial self-stimulation behavior is similar to the action of neuroleptics.
