Purmorphamine activates the Hedgehog pathway by directly binds and activates Smoothened with IC50 of ~ 1.5 μM in compete with cyclopamine, a Smo antagonist.  Purmorphamine is a potent inducer of osteogenesis in multipotent C3H10T1/2 cells. The EC50 (based on ALP expression) for Purmorphamine is 1 μM in C3H10T1/2 cells. Purmorphamine (1 μM) and BMP-4 (100 ng/mL) together increase ALP activity more than 90-fold in 3T3-L1 cells.  In contrast to BMP-4, Purmorphamine induces osteogenesis by activating Hedgehog signaling in multipotent mesenchymal progenitor cells. 
|In vivo||Purmorphamine up-regulates ALP expression in human mesenchymal stem cell-based constructs on rats. |
Binding assay:Smo binding assays are conducted with BODIPY-cyclopamine and Smo-overexpressing cells as previously described4,5, using CMV promoter-based, SV40 origin-containing expression constructs for Smo-Myc3, the deletion mutant SmoCRD (deletion of amino acids 68 to 182), and SmoCT (deletion of amino acids 556 to 793). HEK 293T cells are grown on poly-D-lysine-treated glass coverslips in 12-well plates until 70% confluency and then transfected with the appropriate expression construct (0.5 g/well) using FuGene 6 according the manufacturer's protocols. Two days after transfection, the HEK 293T cells are incubated with DMEM containing 0.5% bovine calf serum, 5 nM BODIPY-cyclopamine, and varying concentrations of Purmorphamine (0, 1.5, or 5 M) (1 mL/well) for 1 h at 37 ℃. The Smo-overexpressing cells are then washed with 1 × PBS buffer (1 mL/well), mounted with DAPI-containing medium, and visualized using a Leica DM4500B fluorescence microscope. For binding assays using fixed cells, the Smo-overexpressing HEK 293T cells are fixed with 3% paraformaldehyde in 1 × PBS buffer for 10 min at room temperature (1 mL/well), treated with 1 × PBS containing 10 mM glycine and 0.2% sodium azide for 5 min (1 mL/well), washed with 1 × PBS buffer (1 mL/well), and treated with the Purmorphamine-containing media described above for 4 h at room temperature.
|In vitro||DMSO||4 mg/mL warmed (7.68 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+5% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (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.
