6-Methoxy-tetrahydro-β-carboline (MTBC) is a sterically hindered analog of serotonin which may be produced endogenously. MTBC stimulated rat prolactin release in a dose-related manner. The onset of the hyperprolactinemic effect was rapid (peak around 15 min) and of short duration (<60 min). Its effect upon serum prolactin was blocked by methysergide, a serotonin receptor blocker, and was potentiated by pretreatment with parachlorophenylalanine, an inhibitor of serotonin synthesis, suggesting its action could be the result of a direct serotonergic effect on the brain.
