Product Description

Milnacipran HCl, a medication used in the clinical treatment of fibromyalgia, is a potent inhibitor of both norepinephrine transporter (NET) and norepinephrine transporter (SERT) with IC50 of 77 nM and 420 nM, respectively. Milnacipran is mainly excreted in the urine as the parent and glucoronide (> 80%), and only a small fraction (< 10%) is metabolized via N-de-ethylation by the CYP3A4 enzyme. Milnacipran at high concentration can inhibit certain ligand-gated ion-channel (LGIC) receptors, including NMDA, 5-HT3A and nACh receptors, with IC50 of 58.4 μM, 185 μM, 14.3 μM.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

In vitro activity: Milnacipran is mainly excreted in the urine as the parent and glucoronide (> 80%), and only a small fraction (< 10%) is metabolized via N-de-ethylation by the CYP3A4 enzyme. Milnacipran at high concentration can inhibit certain ligand-gated ion-channel (LGIC) receptors, including NMDA, 5-HT3A and nACh receptors, with IC50 of 58.4 μM, 185 μM, 14.3 μM.

ln Vivo
Milnacipran (10 and 30 mg/kg, PO) causes a dose-related increase in the extracellular levels of 5-HT and NA in the medial prefrontal cortex of rats. Milnacipran (30 and 60 mg/kg, PO) significantly reduces the duration of both the immobility time in the forced swimming test and the freezing time in the conditioned fear stress test in rats, which are animal behavioral models for depression and anxiety, respectively. Milnacipran (<40 mg/kg i.p.) dose-dependently increases the extracellular levels of NA and 5-HT in hypothalamus of freely moving guinea pigs. Milnacipran administrated at 10 mg/kg and 40 mg/kg decreases NA metabolite MHPG levels by 57% and 47%, respectively, in hypothalamus of freely moving guinea pigs.

Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.84 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to 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.

Solubility in Formulation 2: ≥ 2.5 mg/mL (8.84 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline 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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
