Smoothened agonist (SAG) is a chlorobenzothiophene-containing compound which acts as a SMO agonist (EC50 = 3 nM) but inhibits hedgehog signaling at high concentrations (>1 ?M).{21771} It directly binds to SMO and can block SMO inhibition by cyclopamine.{21771} Binding of SAG alters the conformation of SMO, leading to its accumulation in cilia and activation of gene transcription.{20488,21775,21773} At 15-240 nM, SAG prevents the neurotoxic effects of glucocorticoids without interfering with the beneficial effects of glucocorticoids on lung maturation.{21772} At higher concentrations (0.4 mM), SAG improves the conversion of human induced pluripotent stem cells to the neural lineage.{21770}
