Selective non-lipid inhibitor of sphingosine kinase (IC50 = 0.5 μM); does not act at ATP-binding site. Displays no inhibition of ERK2, PI 3-kinase, or PKCα at concentrations up to 60 μM. Reduces levels of sphingosine-1-phosphate in MDA-MB-231 breast cancer cells. Induces apoptosis and inhibits proliferation in several other tumor cell lines in vitro (IC50 = 0.9 - 4.6 μM).

Preparing Stock Solutions
The following data is based on the product molecular weight 302.78. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||3.3 mL||16.51 mL||33.03 mL|
|5 mM||0.66 mL||3.3 mL||6.61 mL|
|10 mM||0.33 mL||1.65 mL||3.3 mL|
|50 mM||0.07 mL||0.33 mL||0.66 mL|
The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.
