| Targets |
Diclofensine targets the monoamine transporters for dopamine (DAT), norepinephrine (NET), and serotonin (SERT). It is a potent inhibitor of all three transporters, blocking the reuptake of these neurotransmitters from the synaptic cleft. The IC₅₀ values for blocking dopamine, norepinephrine, and serotonin in rat brain synaptosomes are 0.74 nM, 2.3 nM, and 3.7 nM, respectively. This triple reuptake inhibition is the basis for its antidepressant activity.

| ln Vitro |
In vitro, Diclofensine is a potent inhibitor of monoamine reuptake. It blocks the uptake of dopamine, norepinephrine, and serotonin by rat brain synaptosomes with high potency, as shown by its IC₅₀ values of 0.74 nM, 2.3 nM, and 3.7 nM, respectively. This activity profile makes it a classic example of a triple reuptake inhibitor (TRI).
|
| ln Vivo |
In vivo, Diclofensine acts as an antidepressant by increasing the synaptic concentrations of dopamine, norepinephrine, and serotonin. Its triple reuptake inhibition mechanism is expected to produce robust antidepressant effects. However, its clinical development was likely limited due to side effect profiles common to monoamine reuptake inhibitors. It is not currently used clinically.
|
| Enzyme Assay |
In vitro non-cell enzyme/receptor binding assays for Diclofensine typically involve measuring the inhibition of neurotransmitter uptake into synaptosomes (nerve terminals) prepared from rat brain. The synaptosomes are incubated with radiolabeled dopamine, norepinephrine, or serotonin in the presence of varying concentrations of Diclofensine. The amount of radioactivity taken up is measured, and IC₅₀ values are calculated from the inhibition curves.
|
| Cell Assay |
In vitro cell-based assays for Diclofensine use cell lines expressing the human monoamine transporters (hDAT, hNET, hSERT) to determine its potency against the human targets. Cells are incubated with the compound and a fluorescent or radiolabeled substrate, and the inhibition of substrate uptake is measured to calculate IC₅₀ values.
|
| Animal Protocol |
In vivo animal studies for Diclofensine have likely been conducted in rodent models of depression, such as the forced swim test or tail suspension test. The compound would be administered systemically, and its ability to reduce immobility time, indicating antidepressant-like activity, would be assessed. Brain levels of monoamines would also be measured to confirm target engagement.
|
| ADME/Pharmacokinetics |
Diclofensine has a molecular weight of 322.23 g/mol and a molecular formula of C₁₇H₁₇Cl₂NO. It has a LogP of 4.42, indicating moderate lipophilicity. As a small molecule, it is expected to be orally bioavailable and to cross the blood-brain barrier. The compound should be stored as a powder at -20°C for long-term stability.
|
| Toxicity/Toxicokinetics |
Diclofensine's toxicity profile is likely similar to other monoamine reuptake inhibitors, which can include cardiovascular effects, gastrointestinal disturbances, and central nervous system side effects. At high doses, it may cause serotonin syndrome or hypertensive crisis. Comprehensive toxicological data are not publicly available as the compound is a research tool.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.76 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), Clear solution.
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 900 μL of corn oil and mix well. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
