Purmorphamine

Purmorphamine is a small molecule Hh agonist, it directly binds to and activates the 7-transmembrane Smo receptor of the Hedgehog signaling pathway. Hedgehog agonist purmorphamine most significantly increased the neuronal differentiation of a human striatal NSC line (STROC05). Purmorphamine up-regulated gene expression of the mediators of Hh pathway, SMO, PTCH1, GLI1, and GLI2. The activation of Hh pathway by purmorphamine increased the expression of several genes. Purmorphamine triggers Hh signaling pathway in hMSCs, inducing an increase in the expression of a set of genes involved in the osteoblast differentiation program. The EC50 value for differentiation of C3H10T1/2 cells based on alkaline phosphatase expression is 1 µM.
