Proterguride (INNTooltip International Nonproprietary Name; developmental code names VUFB-13416, ZK-39437), also known as 6-propylterguride or 6-propyl-9,10-dihydrolisuride, is a dopamine agonist of the ergoline family described as a prolactin inhibitor and antiparkinsonian agent which was never marketed.^{[1][2][3][4][5]} It is closely structurally related to certain other ergolines like terguride and lisuride.^[1][4] Besides dopamine receptors, the drug also interacts with serotonin, adrenergic, and histamine receptors.^[5] Proterguride was first described in the literature by at least 1981.^[1]

Proterguride (N6-propylterguride or N6-propyldihydrolisuride) is an ergoline derivative with potent dopaminergic activity [124, 125]. It has been reported that strong dopaminergic activity can be achieved at plasma concentrations below 50 pg/mL [125]. Physiologic dopamine receptor stimulation in the human striatum can be simulated by continuous administration of proterguride (PT) [125].
