A new dissociative anesthetic, 3-MeO-PCMo, a morpholine analogue of 3-MeO-PCP, was synthesized and characterized along with five related compounds. All six arylcyclohexylmorpholines were analyzed using chromatographic, mass spectrometric, and spectroscopic techniques, allowing differentiation of positional isomers. In vitro binding studies in rat forebrain preparations showed moderate affinity for the N-methyl-D-aspartate receptor (NMDAR), with 3-Me-PCMo having the highest affinity, followed by 3-MeO-PCMo. 3-MeO-PCMo had affinity comparable to ketamine and approximately 12-fold lower than PCP. These findings support anecdotal reports of dissociative effects from 3-MeO-PCMo in humans.
