Product Description
L-368,899 HCl is a potent, selective, orally bioavailable, non-peptide oxytocin receptor blocker (antagonist) with IC50s of 8.9 nM and 26 nM for rat and human uterine oxytocin receptor, respectively. Anti-preterm labor agent.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
The IC50 values of L-368,899 hydrochloride for rat and human uterine oxytocin receptors are 8.9 nM and 26 nM, respectively. It is a strong, orally accessible, non-peptide oxytocin receptor antagonist. In rat liver and kidney (IC50: 510 nM, 960 nM, 890 nM, and 2400 nM, respectively), L-368,899 exhibits minimal action on VP receptors [1].
ln Vivo
In both rats and dogs, L-368,899 shows comparable pharmacokinetics. The t1/2 of L-368,899 in both species was two hours following a single intravenous administration. Furthermore, in rats or dogs, L-368,899 has a plasma clearance of 23 to 36 ml/min/kg. For dogs, the Vdss values of L-368,899 are 2.0 and 2.6 L/kg and 3.4 to 4.9 L/kg [2]. Oral access to L-368,899 is available. Oral bioavailability in rats at the 5 mg/kg dose was 14% in females and 18% in males. Moreover, oral bioavailability in male and female rats was 41% and 17%, respectively, at a dosage of 25 mg/kg [2].

Solubility Data
Solubility (In Vitro)
DMSO : ~130 mg/mL (~219.88 mM)
H2O : ~50 mg/mL (~84.57 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.17 mg/mL (3.67 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 21.7 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: ≥ 2.17 mg/mL (3.67 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 21.7 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.
