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.
