1-Pyridyl-3,4-dihydro-beta-carbolines (2a-2f) were synthesized by two methods. The central action of these compounds was investigated in mice and rats using behavioral tests. The most active 6-methoxy-1-(3-pyridyl)-3,4-dihydro-beta-carboline (2e) possesses potential antidepressant properties, as it reversed the effects of reserpine (sedation, hypothermia and ptosis), potentiated the stimulation induced by levodopa given jointly with pargyline, and reduced the immobility time in the despair test. Moreover, compound 2e inhibited the spontaneous locomotor activity, evoked tremor and produced an analgesic effect.
