Smoothened agonist (SAG) was one of the first small-molecule agonists developed for the protein Smoothened,^[1] a key part of the hedgehog signaling pathway, which is involved in brain development as well as having a number of other functions in the body.

Smoothened agonist has been shown to aid proliferation and survival of developing neurons,^[2] and prevent drug-induced brain injury.^[3] When injected into the cerebellum of newborn mice with an induced Down syndrome-like condition, Smoothened agonist was able to stimulate normal cerebellum development, resulting in significant behavioural improvement once the mice had grown to adulthood.^[4]

Smoothened Agonist was capable of inducing androgen production in both prostate and bone stromal cells that was significantly greater than even similarly treated prostate cancer cells.^[5]
