Tocinoic acid is a peptide oxytocin receptor antagonist which is used in scientific research.[1] Intracerebroventricular injection of the drug has been found to block the prosocial behavior induced by the serotonin releasing agent MDMA without affecting baseline social behavior in animals.[2][3][4][1] Similar findings have been made for the non-peptide selective oxytocin receptor antagonist L-368899.[2][5] However, in other studies, other oxytocin receptor antagonists have been ineffective in blocking MDMA-induced prosocial behavior.[1][6][7] The reasons for these discrepancies are unclear.[2][1]
