JJC8-088 is a dopamine reuptake inhibitor (DRI) that was derived from the wakefulness-promoting agent modafinil. [1] [2] [3]

It has substantially higher affinity for the dopamine transporter (DAT) than modafinil (Ki = 6.72 nM vs. 2,600 nM; 387-fold). [2] In contrast to modafinil and other analogues, which are atypical DRIs, JJC8-088 is a typical cocaine-like DRI. [1] [3] It has potent cocaine-like psychostimulant effects, produces robust and dose-dependent increases in dopamine levels in the nucleus accumbens, and is readily self-administered by and substitutes for cocaine in animals. [1] [3]

Similarly to cocaine, but unlike modafinil and other analogues, JJC8-088 stabilizes the DAT in an outward-facing open conformation. [1] It has been theorized that cocaine-like DRIs may actually act as dopamine releasing agent-like DAT "inverse agonists" rather than as simple transporter blockers. [4]

In addition to its affinity for the DAT, JJC8-088 has low affinity for the serotonin transporter (SERT) (Ki = 213 nM; 32-fold less than for the DAT) and for the norepinephrine transporter (NET) (Ki = 1950 nM; 290-fold less than for the DAT). [2] It also binds with high affinity to the sigma σ1 receptor (Ki = 41.6 nM). [5]

The drug has high affinity for the hERG antitarget (IC50 Tooltip half-maximal inhibitory concentration = 130 nM) and could produce cardiotoxicity. [6] [7]

A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron. This results in increased extracellular concentrations of dopamine and increase in dopaminergic neurotransmission.

<span class="mw-page-title-main">Dopamine transporter</span> Mammalian protein found in Homo sapiens

The dopamine transporter is a membrane-spanning protein coded for in humans by the SLC6A3 gene, that pumps the neurotransmitter dopamine out of the synaptic cleft back into cytosol. In the cytosol, other transporters sequester the dopamine into vesicles for storage and later release. Dopamine reuptake via DAT provides the primary mechanism through which dopamine is cleared from synapses, although there may be an exception in the prefrontal cortex, where evidence points to a possibly larger role of the norepinephrine transporter.

<span class="mw-page-title-main">(+)-CPCA</span> Stimulant drug

(+)-CPCA is a stimulant drug similar in structure to pethidine and to RTI-31, but nocaine lacks the two-carbon bridge of RTI-31's tropane skeleton. This compound was first developed as a substitute agent for cocaine.

<span class="mw-page-title-main">Monoamine releasing agent</span> Class of compounds

A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the release of a monoamine neurotransmitter from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitter. Many drugs induce their effects in the body and/or brain via the release of monoamine neurotransmitters, e.g., trace amines, many substituted amphetamines, and related compounds.

<span class="mw-page-title-main">JZ-IV-10</span> Chemical compound

JZ-IV-10 is a piperidine derivative related to cocaine which acts as a highly potent serotonin–norepinephrine–dopamine reuptake inhibitor. The eugeroic modafinil was used as a lead to fuel this compound's discovery.

<span class="mw-page-title-main">RTI-83</span> Chemical compound

RTI-83 is a phenyltropane derivative which represents a rare example of an SDRI or serotonin-dopamine reuptake inhibitor, a drug which inhibits the reuptake of the neurotransmitters serotonin and dopamine, while having little or no effect on the reuptake of the related neurotransmitter noradrenaline. With a binding affinity (Ki) of 55 nM at DAT and 28.4 nM at SERT but only 4030 nM at NET, RTI-83 has reasonable selectivity for DAT/SERT over NET

<span class="mw-page-title-main">Serotonin–dopamine reuptake inhibitor</span> Class of drug

A serotonin–dopamine reuptake inhibitor (SDRI) is a type of drug which acts as a reuptake inhibitor of the monoamine neurotransmitters serotonin and dopamine by blocking the actions of the serotonin transporter (SERT) and dopamine transporter (DAT), respectively. This in turn leads to increased extracellular concentrations of serotonin and dopamine, and, therefore, an increase in serotonergic and dopaminergic neurotransmission.

Flmodafinil, also known as bisfluoromodafinil and lauflumide, is a wakefulness-promoting agent related to modafinil which has been developed for treatment of a variety of different medical conditions. These include chronic fatigue syndrome, idiopathic hypersomnia, narcolepsy, attention deficit hyperactivity disorder (ADHD), and Alzheimer's disease. Aside its development as a potential pharmaceutical drug, flmodafinil is sold online and used non-medically as a nootropic.

1-(3-Chlorophenyl)-4-(2-phenylethyl)piperazine (3C-PEP) is a designer drug of the piperazine class of chemical substances. 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 disclosing a series of piperazine compounds as sigma receptor ligands. Later, it was discovered to be a highly potent dopamine reuptake inhibitor.

<span class="mw-page-title-main">JHW-007</span> Atypical dopamine reuptake inhibitor

JHW-007 is a cocaine analogue and a high affinity atypical dopamine reuptake inhibitor that is being researched for the treatment of cocaine addiction. JHW-007 has been found to blunt the psychostimulant effects of cocaine and reduce self-administration in rodents. JHW-007 exposure has been shown to block the conditioned place preference effects of cocaine. JHW-007 may directly antagonize the autoregulatory dopamine D2 receptor, a hypothesis that was developed following the observation of JHW-007's ability to inhibit D2 receptor-mediated currents in the midbrain.
