| Purmorphamine Usage And Synthesis |
| Description | Small molecules that promote osteoblast differentiation might be useful as therapeutic agents for bone diseases such as osteoporosis. Purmorphamine is a 2,6,9-trisubstituted purine that promotes the differentiation of both human and mouse mesenchymal progenitor cells into osteoblasts. The EC50 value for differentiation of C3H10T1/2 cells based on alkaline phosphatase expression is 1 μM. Investigation into purmorphamine’s mechanism of action indicates that it directly binds to and activates the 7-transmembrane Smo receptor of the Hedgehog signaling pathway. | | Chemical Properties | Light Tan Solid | | Uses | An activator of the hedgehog (Hh) signaling pathway. | | Uses | Purmorphamine has been used to study the consequences of upregulation of Hedgehog signalling pathway in Tupfel long fin strain Zebrafish. | | Uses | Activates the Hedgehog pathway by targeting Smoothened | | Definition | ChEBI: A member of the class of purines that is purine substituted at C-2 by a 1-naphthyloxy group, at C-4 by a 4-morpholinophenylamino group, and at N-9 by a cyclohexyl group. | | Biochem/physiol Actions | Purmorphamine activates the Hedgehog (Hh) signaling pathway, directly binding to the Smoothened (Smo) receptor. In various studies, purmorphamine has been shown to induce osteoblast differentiation, generate cardiomyocytes from human embryonic stem cells, increase the neuronal differentiation of a human striatal neural stem cell line, and to differentiate human umbilical cord mesenchymal stem cells (hUCMSCs) into motoneurons. | | in vitro | purmorphamine activated the hedgehog pathway by directly bound and activated smoothened with the ic50value of ~ 1.5 μm in competing with cyclopamine, a smo antagonist [1]. in multi-potent c3h10t1/2 cells, purmorphamine was a potent inducer of osteogenesis. in c3h10t1/2 cells, the ec50 values assessed based on alp expression for purmorphamine was 1 μm. purmorphamine (1 μm) in combination with bmp-4 (100 ng/ml) increased alp activity more than 90-fold in 3t3-l1 cells [3].administration of purmorphamine at 3 and 5 μm up-regulated the level of osteocalcin on day 14 (p ≤ 0.05)[4]. | | in vivo | in rats transplanted with stem cell-based constructs subcutaneously, treatment with purmorphamine tended to up-regulate alp transcripts when compared with those injected by either dexamethasone or injection water (p ≤ 0.05) [4]. | | References | 1) Wu et al.
