Potent, selective antagonist at the rat 5-HT1B receptor (Ki = 47 nM). Increases synthesis and metabolism of 5-HT in the brain following systemic administration and improves passive avoidance retention performance in vivo. Increases subthalamic nucleus-triggered complex EPSCs and burst firing in SNr GABA neurons
