Psychotridine is an alkaloid found in some species of the Psychotria genus, namely Psychotria colorata,[1] but also Psychotria forsteriana,[2] Psychotria lyciiflora,[3] Psychotria oleoides,[3] and Psychotria beccarioides.[4] Psychotridine has analgesic effects and dose-dependently inhibits dizocilpine binding to cortical membranes in vitro, suggesting that it acts as a non-competitive NMDA receptor antagonist.[1]
