1-(3-Chlorophenyl)-4-(2-phenylethyl)piperazine (3C-PEP) is a
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.[1] Later, it was discovered to be a highly potent dopamine reuptake inhibitor.[2]
Pharmacology
3C-PEP is one of the most potent
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 D2-like receptor (Ki = 327 nM), serotonin 5-HT2 receptor (Ki = 53 nM), opioid receptor (Ki > 10000 nM), and the PCP/NMDA receptor (Ki > 10000 nM).[2]
With a DAT dissociation constant Ki of 0.04 nM, 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.
