Nomifensine maleate
Based on 6 publication(s) in Google Scholar
Nomifensine ((±)-Nomifensine) maleate is a potent norepinephrine (NE) and dopamine (DA) reuptake inhibitor. Nomifensine maleate inhibits uptake of NE, DA and 5-HT in rat brain synaptosomes, with IC50 values of 6.6 nM, 48 nM and 830 nM, and Ki values of 4.7 nM, 26 nM and 4000 nM, respectively. Nomifensine maleate has antidepressant and analgesic effects. Nomifensine maleate is used in neurodegenerative diseases, compound addiction, and pain research.

Biological Activity
Nomifensine (5 mg/kg/day; s.c. using minipumps; 2-14 days) maleate potently and significantly inhibits dopamine neuronal firing in the ventral tegmental area of SD rats after 2 days, with recovery to normal after 14-day treatment due to D2 autoreceptor desensitization[4].
Nomifensine (0.625-5 mg/kg; s.c.; 30 min before testing) maleate produces analgesia (only in the formaldehyde test) and abolishs the nociceptive behavior induced by 2% formaldehyde in rats[6].
Nomifensine (20 mg/kg; i.p.; once a day; 6 consecutive days) maleate can suppress the neurotoxicity of MPTP (HY-15608) in C57 black mice, inhibiting the long-term depletion of neostriatal DA concentration induced by MPTP[7].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.75 mg/mL (7.76 mM); Clear solution

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.75 mg/mL (7.76 mM); Clear solution
This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
