Purmorphamine is a small molecule that promotes the differentiation of human and murine mesenchymal progenitor cells into osteoblasts1,2. The mechanism of action study of Purmorphamine indicates that it is an agonist of Smoothened, a 7-transmembrane receptor of the hedgehog signaling pathway3,4. Purmorphamine can also be used to replace sonic hedgehog for the generation of motor neurons from human embryonic stem cells5.

For a 10 mM concentrated stock solution of Purmorphamine, reconstitute the compound by adding 960.4 µL of DMSO to the entire contents of the vial. If precipitate is observed, warm the solution to 37 °C for 2 to 5 minutes. For use in cell culture, warm the medium just prior to adding the reconstituted compound. Once the compound is added, mix and filter-sterilize the medium using a 0.2 uM low-protein binding filter. Purmorphamine is soluble in DMSO at 50 mM.
Storage and Stability
Store powder at 4 °C protected from light. Information about the stability of Stemolecules in solution is largely not available. As a general guideline, we recommend that stock solution be freshly made and stored in aliquots at −20 °C, protected from light. The effect of storage of stock solutions should be verified for each application.
The purity of Purmorphamine was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. No acute cytotoxicity was observed in mouse embryonic stem cells following a 6 hour exposure to 1 nM — 100 uM of Purmorphamine.
