Product Description
Ecopipam (SCH 39166) HCl is a potent, selective, orally bioactive dopamine D1/D5 receptor blocker (antagonist) with Kis of 1.2 nM and 2.0 nM, respectively. Ecopipam HCl has over 40-fold selectivity for D2, D4, 5-HT and α2a receptors (Ki=0.98, 5.52, 0.08 and 0.73 μM). Ecopipam HCl may be utilized in the research into schizophrenia and obesity.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
In the isolated basal hippocampal formation, the proconvulsant effects of dopamine (10 μM) are totally eliminated by ecopipam (2 μM) hydrochloride [2].
ln Vivo
Ecopipam hydrochloride (0.003-0.3 mg/kg; single dosage; subcutaneous injection) removes the potentiating effects of island nicotine inducers as sensory enhancers [3]. Ecopipam Hydrochloride (10 mg/kg, Intermediate) Overlapping Antioxidants in Apomorphine-Induced Stereotypy Ecopipam Hydrochloride (5 and 10 μM, perfusion, 1 μL/min) reversibly and dose-dependently decreases striatal apomorphine Release of choline [5].
Animal Protocol
Animal/Disease Models: Male youth Long-Evans impression [4]. Nicotine injected rats [3] Doses: 0.003, 0.01, 0.03, 0.1, 0.3 mg/kg
Route of Administration: Single subcutaneous injection 20 minutes before nicotine (0.1 mg/kg)
Experimental Results: Pressure on active and inactive levers diminished in a dose-dependent manner.

Solubility Data
Solubility (In Vitro)
DMSO : ~100 mg/mL (~285.49 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.14 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 (7.14 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
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.
