A less well-known dissociative research chemical in the arylcyclohexylamine class, O-PCE (Eticyclidine) has been shown in tests to produce anesthetic, hallucinogenic, and NMDA antagonist effects. O-PCE, which shares structural similarities with compounds such as MXE, 3-MeO-PCE, and Deschloroketamine (DCK), has gained attention as a molecule for the investigation of dissociation, receptor binding affinity, and new psychoactive chemicals.
