3-HO-PCP acts as a high-affinity uncompetitive antagonist of the NMDA receptor via the dizocilpine (MK-801) site (Ki = 30 nM). It has much higher affinity than PCP for this site (Ki = 250 nM, for comparison; 8-fold difference). The drug also has high affinity for the μ-opioid receptor (MOR) (Ki = 39–60 nM), the κ-opioid receptor (KOR) (Ki = 140 nM), and the sigma σ1 receptor (Ki = 42 nM; IC50 = 19 nM), whereas it has only low affinity for the δ-opioid receptor (Ki = 2,300 nM). The high affinity of 3-HO-PCP for opioid receptors is unique among arylcyclohexylamines and is in contrast to PCP, which has only very low affinity for the MOR (Ki = 11,000–26,000 nM; 282- to 433-fold difference) and the other opioid receptors (Ki = 4,100 nM for the KOR and 73,000 nM for the DOR).
3-HO-PCP is an arylcyclohexylamine. Close analogues of 3-HO-PCP include PCP, 3-MeO-PCP, 4-MeO-PCP, 3-MeO-PCMo, and somewhat more distantly ketamine, methoxyketamine, 3-MeO-PCE, and methoxetamine.
Society and culture
On October 18, 2012 the Advisory Council on the Misuse of Drugs in the United Kingdom released a report about methoxetamine, saying that the "harms of methoxetamine are commensurate with Class B of the Misuse of Drugs Act (1971)", despite the fact that the act does not classify drugs based on harm. The report went on to suggest that all analogues of MXE should also become class B drugs and suggested a catch-all clause covering both existing and unresearched arylcyclohexamines, including 3-HO-PCP.
