1-(3-chlorophenyl)-4-(2-phenylethyl)piperazine (3C-PEP) is a psychoactive recreational drug of the piperazine class. 3C-PEP is related to meta-Cholorophenylpiperazine (mCPP) and Phenethylamine that can be thought of as mCPP having a phenylethyl group attached to the nitrogen atom at its 4-position. It was first described in 1994 in a patent[1] disclosing a series of piperazine compounds as Sigma receptor ligands. Later, it was discovered by researchers at the University of Maryland to be a highly potent dopamine reuptake inhibitor.[2] Rather serendipitously, since the investigators were looking for compounds that bind to the Sigma receptor as Sigma ligands have been proposed as potential treatment of psychostimulant abuse including cocaine and methamphetamine abuse.

Pharmacology

3C-PEP is one of the most potent dopamine transporter (DAT) ligand reported to date. It is highly selective for the dopamine transporter (DAT dissociation constant Ki = 0.04nM) with relatively low affinity for the closely related Norepinephrine transporter NET (Ki = 1107nM ) and the Serotonin Transporter SERT (Ki = 802 nm). In addition, the compound has little or no affinity for D2-like receptor (Ki = 327nM), Serotonin 5-HT2 receptor, (Ki = 53nM) Opioid receptor (Ki>10000nM) and the PCP/NMDA receptor (Ki>10000nM). [2] With a DAT dissociation constant Ki of 0.04nM, 3C-PEP is one of the most potent dopamine transporter ligand described to date in the literature. In comparison, cocaine which is a prototypical DAT ligand and reuptake inhibitor has a dissociation constant Ki of 435 nm thus making 3C-PEP about 10,000 times more potent than cocaine as a dopamine transporter inhibitor in vitro.[2]

Legal status

United States

3C-PEP is not scheduled at the federal level in the United States,[3]

Canada

3C-PEP is not scheduled under the Controlled Drugs and Substances Act.
