3-MeO-PCMo is a dissociative anesthetic drug which is similar in structure to phencyclidine[1][2] and been sold online as a designer drug.[3][4] The inhibitory effect of 3-MeO-PCMo on the reduction in the density of the drebrin clusters by NMDAR stimulation with glutamic acid is lower than that of PCP or 3-MeO-PCP, with half maximal inhibitory concentration (IC50) values of 26.67 μM (3-MeO-PCMo), 2.02 μM (PCP) and 1.51 μM (3-MeO-PCP).[5]
