  • Activating Shh signaling by SAG injection in naïve mice significantly increased BDNF expression, and pretreatment with cyclopamine effectively prevented the upregulation of BDNF induced by SAG (E). Tissues were collected at 2 hours after SAG injection. Six mice were included in each group.

Biological Activity

Description Smoothened Agonist (SAG) HCl is a cell-permeable Smoothened (Smo) agonist with EC50 of 3 nM in Shh-LIGHT2 cells.
Smoothened [1]
(mouse cultured cell assay)
3 nM(EC50)
In vitro

SAG regulates Smo activity by binding directly to the Smo heptahelical bundle. [1] SAG induces Smo-dependent signaling through Gli in a GRK2-dependent way. [2] SAG also (1 nM) induces proliferation of neuronal and glial precursors without affecting the differentiation pattern of newly produced cells. [3]

Western blotting for LC3I/II. Huh7, Hep3B and HepG2 cells were incubated with vehicle control, SAG (0.5 µM), Pur (10 µM), Shh (0.4 µg/ml), GANT61 (20 µM) or GDC0449 (20 µM) for 48 hours.


PubMed: 25636740     

In the absence of SAG, Smo is not detected at the cilium. MRT-92 alone does not induce Smo trafficking to the primary cilium. Cell exposure to SAG induces Smo trafficking to the cilium, which is abolished by MRT-92.

TM3 cells were cultured in the presence of the SMO agonist (SAG) to monitor response to HH activation. A) In control cells (a-c; 0 h), primary cilia marked by Ac-T (red; arrows) only displayed occasional, speckled appearance of SMO (green). After 1 h in the presence of 100 nM SAG (d-f), a stronger and more frequent localization of SMO to the primary cilia was observed, now also at the ciliary base (f; insert; arrow), and this was even more apparent after 4 h of SAG-stimulation (g-i). Nuceli were stained with DAPI. Scale bar = 10 μm.

In vivo In the adult rat hippocampus, the intracerebroventricular administration of SAG (2.5 nM) significantly increases the number of newly generated cells and extends survival of hippocampal cells. [3] In mice, SAG (20 μg/g, i.p.) effectively prevents GC-induced neonatal cerebellar developmental abnormalities. [4]

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
