3C-PEP, also known as 1-(3-chlorophenyl)-4-(2-phenylethyl)piperazine, is a designer drug of the piperazine class of chemical substances. 3C-PEP is related to meta-cholorophenylpiperazine (mCPP) and phenethylamine which 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 disclosing a series of piperazine compounds as sigma receptor ligands. Later, it was discovered to be a highly potent dopamine reuptake inhibitor.

Pharmacology

3C-PEP is one of the most potent dopamine transporter (DAT) ligands reported to date. It is highly selective for the dopamine transporter (dissociation constant Ki = 0.04 nM) with relatively low affinity for the closely related norepinephrine transporter (NET, Ki = 1107 nM ) and the serotonin transporter (SERT, Ki = 802 nM). In addition, the compound has lower (or no) affinity for the PCP/NMDA receptor (Ki > 10000 nM), D2-like receptors (Ki = 327 nM), serotonin 5-HT2 receptors (Ki = 53 nM), and opioid receptors (Ki > 10000 nM).

With a DAT dissociation constant Ki of 0.04 nM, 3C-PEP is one of the most potent dopamine transporter ligands 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.
