Orally active, full agonist at 5-HT1A receptors. Binds rat 5-HT1A with high affinity (Ki = 2.0 nM) and is > 300-fold selective over other 5-HT receptor subtypes (IC50 > 650 nM). Increases motoneuron survival and promotes effects of NGF on neurite outgrowth in vitro. Displays neurotrophic activity in several neurodegenerative models in vivo..
