Stemolecule Dorsomorphin dihydrochloride (also known as Compound C) is a potent inhibitor of AMP-activated protein kinase (AMPK) (Ki=109nM) and bone morphogenic protein (BMP) signaling1,2. It was identified in a screen for compounds that perturb dorsoventral axis formation in zebrafish3. Dorsomorphin functions through inhibition of BMP type I receptors ALK2, ALK3 and ALK6 and thus blocks BMP-mediated SMAD1/5/8 phosphorylation3. BMP signaling coordinates developmental patterning and have essential physiological roles in mature organisms4,5. Dorsomorphin has been used to probe BMP signaling in iron-hepcidin homeostasis, cardiomyogenesis and osteogenesis3,6,7.


Product Name: Stemolecule Dorsomorphin

Catalog Number: 04-0024

Size: 2 mg

Alternate Name(s)

  • Compound C
  • 6-[4-(2-piperidin-1-ylethoxy)phenyl]-3-pyridin-4-ylpyrazolo[1,5-a]pyrimidine

Chemical Formula: C24H25N5O.2·HCl·H2O

Molecular Weight: 490.43

CAS Number: 866405-64-3

Purity: Greater than 99% by HPLC analysis

Formulation: Yellow solid

Solubility: For a 10 mM concentrated stock solution of Dorsomorphin, reconstitute the compound by adding 407.8 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 cell culture, the media should be prewarmed prior to adding the reconstituted compound. Note: for most cells, the maximum tolerance to DMSO is less than 0.5%. This molecule is soluble in DMSO at 20 mM and water at 100 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.

Quality Control: The purity of Dorsomorphin was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. Cellular toxicity of Dorsomorphin was tested on mouse embryonic stem cells.
