Product Description
AZ8838 is a potent, competitive, allosteric, orally bioactive PAR2 non-peptide small molecule antagonist (inhibitor) with pKi of 6.4 for hPAR2.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
AZ8838 is kept in a closed pocket [1]. In Ca2+ assay, AZ8838 is a strong antagonist of SLIGRL-NH2, having a pIC50 of 5.70 ± 0.02[1]. AZ8838 shown efficacy in suppressing IP1 synthesis (pIC50 = 5.84 ± 0.02) [1]. AZ8838 inhibits peptide-induced ERK1/2 phosphorylation (pIC50 = 5.7 ± 0.1) and β-arrestin-2 recruitment (pIC50 = 6.1 ± 0.1) [1].
ln Vivo
A PAR2 agonist-induced rat paw edema model has demonstrated anti-inflammatory effects with AZ8838 (10 mg/kg; oral; 2 hours ago) [1].
Animal Protocol
Animal/Disease Models: Wistar rat, acute edema model induced by PAR2 agonist 2f-LIGRLO-NH2 [1]
Doses: 10 mg/kg
Route of Administration: Oral administration, once, 2 hrs (hrs (hours)) ago
Experimental Results: demonstrated a 60% reduction in foot swelling . Inhibition of 2f-LIGRLO-NH2 induces activated mast cells, inhibition of 2f-LIGRLO-NH2 reduces tryptase-positive (AA1+ve) intact mast cells in the paw, and blocks histamine release.

Solubility Data
Solubility (In Vitro)
DMSO : ~200 mg/mL (~853.72 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 5 mg/mL (21.34 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 50.0 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: ≥ 5 mg/mL (21.34 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 50.0 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.

Solubility in Formulation 3: ≥ 5 mg/mL (21.34 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 50.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 4.2686 mL 21.3429 mL 42.6858 mL
5 mM 0.8537 mL 4.2686 mL 8.5372 mL
10 mM 0.4269 mL 2.1343 mL 4.2686 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
