dopamine reuptake inhibitor
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 do ...

Cocaine dependence is a neurological disorder that is characterized by withdrawal symptoms upon cessation from cocaine use. It also often coincides with cocaine addiction which is a biopsychosocial disorder characterized by persistent use o ...
. JHW-007 has been found to blunt the psychostimulatory effects of cocaine and reduce self-administration in rodents.
JHW-007 exposure has been shown to block the conditioned place preference effects of cocaine.

receptor agonist.
Atypical dopamine reuptake inhibition
In contrast to cocaine and other cocaine-like dopamine reuptake inhibitors, JHW-007 binds to the dopamine transporter (DAT) in an occluded (closed) conformation, similar to
R-modafinil.
This type of receptor binding to the DAT has been observed to result in a gradual and sustained increase in extracellular dopamine in the nucleus accumbens. Peak levels of extracellular dopamine are also markedly reduced. Both
modafinil and JHW-007 have been investigated for the treatment of cocaine addiction.
