SAG, a highly potent agonist of SMO (smoothened). This small molecule compound activates the hedgehog pathway by directly binding to SMO. Note: in the Gli-1 reporter gene assay, SAG acts as an activator at concentrations from approximay 1 nM to 1 uM, but as an inhibitor at concentrations high than 1 uM.
Purity: Greater than 98% as determined by LC/MS analysis. LC/MS and/or NMR data available upon request.
Biological Activity: In a cell-based assay measuring the activation of the Gli-1 reporter gene, this compound gives EC50 of 5-15 nM.
