Product Description
Itopride (HSR803 free base) is a potent dopamine-2 antagonist and acetylcholinesterase (AChE) inhibitor. Itopride increases gastric motility through antidopaminergic and antiacetylcholinester effects and may be used as a gastrointestinal prokinetic agent. Itopride may be utilized in study/research of gastroesophageal reflux disease (GERD).
Biological Activity I Assay Protocols (From Reference)
ln Vitro
The prokinetic action of icopride hydrochloride is regulated by the antagonistic effect on dopamine D2 receptors and the inhibitory effect on AChE in both the colon and the ileum [3]. In the ileum of guinea pigs, itopride hydrochloride (0.1 nM-1 μM) dramatically increases the rate of peristalsis propagation [3].
ln Vivo
In comparison to the vehicle group, itopride hydrochloride (30 mg/kg; oral) dramatically accelerated stomach emptying [4]. Oral ilopride hydrochloride (30 mg/kg) exhibits a T1/2 of 24.9 min and a Cmax of 358 ‰ [4].
Animal Protocol
Animal/Disease Models: Male ddY strain mouse (23.7-28.5 g) [2]
Doses: 3 mg/kg, 10 mg/kg, 30 mg/kg
Route of Administration: Oral
Experimental Results:Accelerated gastric emptying at 30 mg/kg dose .

Animal/Disease Models: Male ddY strain mouse (23.7-28.5 g) [2]
Doses: 3 mg/kg, 10 mg/kg, 30 mg/kg (pharmacokinetic/PK/PK analysis)
Route of Administration: Oral
Experimental Results:Cmax (358 ‰), T1 /2 (24.9 minutes), dose 30 mg/kg.

Solubility Data
Solubility (In Vitro)
DMSO : ~100 mg/mL (~253.24 mM)
H2O : ~50 mg/mL (~126.62 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.33 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.

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

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.
