SAG is a synthetic chlorobenzothiophene-containing Hh pathway agonist that regulates smo activity. It is a SMO agonist at EC50 of 3 nM and but inhibits hedgehog signaling at >1 μM. 
Smoothened (SMO) is a GPCR-like receptor that mediates hedgehog signaling with Patched to regulate gene expression through the Gli transcription factors. It is plays an important role for embryogenesis and adults tissue homeostasis
In a mouse cultured cell assay (Shh-LIGHT2), SAG induces pathway activation (EC50 ≈3 nM). It differs in that pathway activity decreases dramatically as SAG concentration surpasses 1 μM.  SAG binds directly to the SMO heptahelical bundle. SAG dose dependently blocks this association and produces apparent dissociation constant (KD) of 59 nM for the SAG/SMO complex. 
SAG also antagonizes GC’s antiproliferative effects in CGNP P4 wild-type mice primary cultures. At 15-240 nM, SAG prevents the neurotoxic effects of glucocorticoids without interfering with the beneficial effects of glucocorticoids on lung maturation.
