| Bioactivity | Purmorphamine is a smoothened/Smo receptor agonist with an EC50 of 1 μM. | ||||||||||||
| Target | IC50: 1.5 μM (Smoothened) | ||||||||||||
| Invitro | Purmorphamine (10, 20 μM) in combination with sirolimus significantly decreases cell numbers according to the MTT assay. Purmorphamine induces up-regulation of alkaline phosphatase activity and expression of RUNX-2 at day 14. Up-regulation of osteocalcin is detected at the 3 and 5 μM doses of purmorphamine on day 14 post-induction. Matrix mineralization remains unchanged in the presence or absence of purmorphamine[1]. Purmorphamine induces STAT3 phosphorylation in mouse ES cell line ES14 and mesenchymal stem cell line C3H10T1/2[2]. Purmorphamine up-regulates the expressionof markers of the osteoblast phenotype-ALP activity and bone-like nodule formationd-in human bonemarrow mesenchymal cells[3]. | ||||||||||||
