Product Description
Acoltremon (WS-12; AR-15512) is a potent and specific TRPM8 agonist, an analogue of menthol that works as a coolant. WS-12 displays analgesic effects and may be utilized in study/research of chronic neuropathic pain.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
In tests involving heterologously produced TRP ion channels, Acoltremon (10 μM) exhibits TRPM8 agonism [1]. In DRG neurons, acoltremon (1 or 10 μM; 0-250 s) seems to be a very strong and selective TRPM8 channel agonist [1].
ln Vivo
In mice, acoltremon (ip; 10 mg/kg; once) produces analgesic effects by activating TRPM8 specifically [1].
Cell Assay
Cell Viability Assay[1]
Cell Types: HEK293T Cell
Tested Concentrations: 10 μM
Incubation Duration:
Experimental Results: Activates mouse TRPM8 (mTRPM8), but neither activates nor inhibits mTRPA1.

Cell viability assay[1]
Cell Types: Cultured Mouse DRG Neurons
Tested Concentrations: 1 or 10 μM
Incubation Duration: 0-250 s
Experimental Results: Approximately 10% to 14% of cultured wild-type neurons were shown to respond to WS-12 .
Animal Protocol
Animal/Disease Models: Trpm8–/– mice and capsaicin-injected mice [1]
Doses: 10 mg/kg
Route of Administration: intraperitoneal (ip) injection; 10 mg/kg; primary
Experimental Results:significant analgesic effect in Trpm8-/ -The effect is lost in mice. In the rotarod test, mice demonstrated no change in latency decline. Reducing capsaicin-induced nociceptive behavior.

Solubility Data
Solubility (In Vitro)
DMSO : ~20 mg/mL (~69.11 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2 mg/mL (6.91 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 20.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 3.4552 mL 17.2759 mL 34.5519 mL
5 mM 0.6910 mL 3.4552 mL 6.9104 mL
10 mM 0.3455 mL 1.7276 mL 3.4552 mL

*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
g/mol

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Reconstitution Calculator allows you to calculate the volume of solvent required to reconstitute your vial.

  • Enter the mass of the reagent and the desired reconstitution concentration as well as the correct units
  • Click the “Calculate” button
  • The answer appears in the Volume (to add to vial) box

Method for preparing DMSO stock solution mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.

Method for preparing in vivo formulation:Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
             (2) Be sure to add the solvent(s) in order.
