Product Description
KI-7 is an A2B adenosine receptor-positive allosteric modulator (PAM). KI-7 enhances cAMP accumulation induced by the non-selective A2B adenosine receptor agonist (activator) NECA (EC50=445.8 nM). KI-7 also enhanced cAMP accumulation induced by the selective A2B adenosine receptor agonist (activator)s BAY 60-6583 and adenosine, with EC50s of 2390 nM and 2550 nM, respectively.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Runx2 and Osterix mRNA expression can be significantly increased by KI-7 (1 μM; 5–21 days; mesenchymal stem cells) [1]. Cell viability is significantly increased at both differentiation stages by KI-7 (1 μM; 15–21 days) [1]. It has been demonstrated that KI-7, a positive allosteric modulator of the A2B adenosine receptor in MSCs, enhances the in vitro osteoblast differentiation-promoting actions of both adenosine and synthetic orthosteric A2B adenosine receptor agonists. KI-7, BAY 60-6583, and NECA all significantly increased the production of IL-6. Even though this effect only becomes noticeable at day 21, KI-7 amplifies the effects of orthotopic agonists at both differentiation stages [1].

Solubility Data
Solubility (In Vitro)
DMSO : ~250 mg/mL (~705.42 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.87 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 20.8 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 2.8217 mL 14.1084 mL 28.2167 mL
5 mM 0.5643 mL 2.8217 mL 5.6433 mL
10 mM 0.2822 mL 1.4108 mL 2.8217 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.
