Purmorphamine
Purmorphamine is the first small-molecule agonist developed for the protein Smoothened [1]. Purmorphamine activates the Hedgehog (Hh) signaling pathway, resulting in the up- and downregulation of its downstream target genes, including Gli1 and Patched. Purmorphamine may ultimately be useful in the treatment of bone-related disease andneurodegenerative disease [2].
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].

| Applications | Modulation of Hh signaling by purmorphamine in hMSCs was evaluated at 7 and 14 days through the gene expression of the membrane receptors SMO and PTCH1, and the transcriptional factors GLI1 and GLI2. Gene expression of SMO was up-regulated at 7 days (P≤0.05) and down-regulated at 14 days (P≤0.05) by purmorphamine. PTCH1 expression was increased by purmorphamine at 7 days (P≤0.05) and not affected at 14 days (P≤0.05). Purmorphamine up-regulated the expression of GLI1 and GLI2 at 7 (P≤ 0.05) and 14 days (P≤0.05). |

| Applications | Subcutaneous transplantation of human mesenchymal stem cell-based constructs into rats. According to the histology sections, labeled cells were present inside the scaffolds. Based on real-time PCR results, it has been shown the up-regulation of human osteoblast genes, ALP, osteocalcin, Runx-2, and collagen I in transplanted cell constructs. |
| Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
