3-MeO-PCE (3-Methoxyeticyclidine) Product Description

Introduction

3-Methoxyeticyclidine, abbreviated as 3-MeO-PCE, is a synthetic dissociative anesthetic from the arylcyclohexylamine class. It is a methoxy-substituted analog of eticyclidine (PCE), differing by the presence of a methoxy group at the 3-position on the phenyl ring. 3-MeO-PCE has gained attention as a designer drug and research chemical with potent dissociative properties comparable to ketamine and PCP. It is primarily employed in scientific research to investigate NMDA receptor antagonism, pharmacodynamics, and toxicology. The compound is not approved for medical use.

Pharmacological Profile and Mechanism of Action

Proposed Mechanism of Action

3-MeO-PCE acts as a potent non-competitive NMDA receptor antagonist, inhibiting glutamate neurotransmission responsible for excitatory signaling in the brain and spinal cord. Binding affinity (Ki) for the NMDA receptor is approximately 61 nM, indicating greater potency than ketamine. It displays secondary interactions with monoamine transporters including moderate affinity for dopamine and serotonin transporters, with weaker binding to histamine and adrenergic receptors. The dissociative effects arise chiefly through NMDA receptor blockade.

Research Applications

3-MeO-PCE provides an important molecular tool for studying the pharmacology of dissociative anesthetics, NMDA receptor physiology, and neurotoxicity. It finds use in forensic toxicology and analytical chemistry to identify emerging designer dissociatives in biological and environmental samples.

Comparison to PCE, 3-HO-PCE, and 3-MeO-PCP

3-MeO-PCE shares close similarity with eticyclidine (PCE), differing by its methoxy group at the 3-position. Compared to 3-HO-PCE, it has a methoxy instead of hydroxy substitution, impacting pharmacokinetics and receptor affinity. Its NMDA receptor affinity is similar to 3-MeO-PCP but differs in other receptor interactions and side effect profiles, providing diverse applications in receptor binding studies.

Advantages for Research

High potency NMDA antagonist for detailed pharmacodynamic investigations.
Chemical stability and purity facilitate reproducible laboratory experimentation.
Serves forensic and toxicological methodologies to identify designer dissociatives.
