Product Description
MRT-81 is a potent antagonist of human and rodent smoothened (Smo) receptors with IC50 of 41 nM in Shh-light2 cells. MRT-81 has potent hedgehog inhibitory activity. MRT-81 could be used in cancer research.
Biological Activity I Assay Protocols (From Reference)
Targets
IC50: 41 nM (Shh-light2 cells Smo receptors)[1]
ln Vitro
MRT-81 inhibits the Smo agonist SAG (0.1 μM)-induced differentiation of mesenchymal pluripotent C3H10T1/2 cells into alkaline phosphatasepositive osteoblasts, with an IC50 value of 64 nM[1]. With an IC50 less than 10 nM, MRT-81 (1-1000 nM) is a strong antagonist of SAG (0.01 μM)-induced rat granule cell precursors (GCPs) proliferation[1]. In HEK-hSmo cells, MRT-81 (0, 0.1, 1, 10, 30, 100, 300, 1000 nM; 2 h; 37 °C) inhibits the binding of BODIPY-cyclopamine (5 nM) to hSmo in a dose-dependent manner, with an IC50 of 63 nM[1].

Solubility Data
Solubility (In Vitro)
DMSO: 100 mg/mL (179.97 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.50 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 25.0 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 1.7997 mL 8.9986 mL 17.9973 mL
5 mM 0.3599 mL 1.7997 mL 3.5995 mL
10 mM 0.1800 mL 0.8999 mL 1.7997 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
