| Targets |
3-CPMT targets the dopamine transporter (DAT) with high affinity, exhibiting a Ki of 30 nM. It blocks the re-uptake of dopamine by binding to the DAT. The compound's tropane scaffold is responsible for its interaction with the monoamine transporter.

|---|---|
| ln Vitro |
In cell-free binding assays, 3-CPMT demonstrates high-affinity binding to the dopamine transporter with a Ki of 30 nM. Radioligand displacement studies confirm its potent interaction with the DAT binding site. The compound's affinity for DAT is comparable to that of cocaine, yet its behavioral profile is markedly different. In cellular uptake assays, 3-CPMT potently inhibits dopamine reuptake in neurons. The compound blocks DAT-mediated dopamine transport, leading to increased extracellular dopamine levels. Despite its potent dopamine uptake inhibition, it is a weak psychomotor stimulant and does not produce cocaine-like effects in behavioral models.
|
| ln Vivo |
In vivo behavioral studies demonstrate that 3-CPMT does not display a cocaine-like behavioral profile despite its ability to inhibit dopamine uptake. It is a weak psychomotor stimulant and does not substitute for cocaine in addicted rats. This unique profile makes 3-CPMT valuable for understanding the relationship between DAT inhibition and psychostimulant effects.
|
| Enzyme Assay |
Dopamine transporter binding assays for 3-CPMT are performed using membrane preparations from cells or tissues expressing DAT. Radioligand binding studies use [³H]WIN 35,428 or similar DAT-selective ligands. Membranes are incubated with varying concentrations of 3-CPMT and the radioligand, followed by filtration and scintillation counting. Ki values are calculated from competition binding curves.
|
| Cell Assay |
Dopamine uptake inhibition assays are conducted using neuronal cell cultures or synaptosomal preparations. Cells are pre-incubated with 3-CPMT at various concentrations, then [³H]dopamine is added. Uptake is terminated after a defined period, and accumulated radioactivity is measured. IC50 or Ki values are determined from concentration-response curves.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties of 3-CPMT have been characterized in rodent models. The compound is capable of crossing the blood-brain barrier due to its lipophilic nature. Its long-acting antihistaminic properties suggest extended duration of action. Detailed PK parameters including half-life and bioavailability require further characterization.
|
| Toxicity/Toxicokinetics |
Preclinical toxicity studies on 3-CPMT are limited. In behavioral studies, the compound is administered at various doses without significant adverse effects reported. Its weak psychomotor stimulant profile suggests a lower abuse liability compared to cocaine. The compound's antihistaminic activity may contribute to its safety profile.

| Additional Infomation |
3-CPMT is a cocaine analog that binds with a high affinity to the dopamine transporter and blocks the reabsorption of dopamine.
3-CPMT is a research tool for studying dopamine transporter function and the mechanisms of psychostimulant action. Its unique property of inhibiting dopamine uptake without producing cocaine-like effects makes it valuable for understanding the dissociation between DAT inhibition and behavioral stimulation. The compound is also known for its antihistaminic activity. |

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of DMSO stock solution (25.0 mg/mL) to 400 μL of PEG300 and mix well; then add 50 μL of Tween-80 and mix well; finally add 450 μL of physiological saline and adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
