SAG is a potent, selective, and cell-permeable small-molecule agonist of the Hedgehog pathway. It modulates the coupling of Smo with its downstream effector by interacting with the Smo heptahelical domain (KD = 59 nM). SAG induces Hedgehog pathway activation with an EC50 of ~3 nM in NIH 3T3-derived Shh-LIGHT2 cells and counteracts Cyclopamine-KAAD inhibition of Smo. It was reported that SAG acts as an activator at low concentrations and as an inhibitor at high concentrations (>1 µM). In recent studies, SAG was shown to prevent glucocorticoid-induced neonatal cerebellar injury, and trigger rapid metabolic rewiring via AMPK.
