CTDP-32476

CTDP-32476 is an atypical, highly potent dopamine reuptake inhibitor investigated as a potential pharmacotherapy for cocaine addiction.^[1][2][3] Unlike cocaine, which acts as a serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI) by rapidly blocking reuptake of all three monoamines, CTDP-32476 is highly selective for the dopamine transporter (DAT) and does not significantly block either the serotonin or norepinephrine transporters. Its slow-onset and long-duration effects are thought to result from pharmacokinetic properties such as delayed absorption and slower diffusion across the blood-brain barrier (BBB), resulting in a much lower risk of abuse compared to cocaine.^{[citation needed]} However, the evidence for slower BBB penetration is indirect and inferred primarily from behavioral and neurochemical profiles rather than direct permeability measurements. While agonist-replacement therapies have been effective for opiate and nicotine dependence, there is currently no reliably successful agent for cocaine addiction.^[4]

The two enantiomers were labeled ATDP-34209 and ATDP-34210. Their absolute configurations were determined by X-ray crystallography. ATDP-34210 is the RR enantiomer corresponding to the active RR enantiomer of methylphenidate. Both the SS and the RR enantiomers have similar activities.^[3]
