SAG hydrochloride 是一种有效的Smoothened (Smo)受体激动剂 (EC50=3 nM;Kd=59 nM)。SAG hydrochloride 可激活 Hedgehog 信号通路并抵消 Cyclopamine (HY-17024) 对 Smo 的抑制作用。
生物活性 | SAG hydrochloride is a potentSmoothened (Smo) receptoragonist (EC50=3 nM;Kd=59 nM). SAG hydrochloride activates theHedgehogsignaling pathway and counteracts Cyclopamine (HY-17024) inhibition ofSmo[1][2][3]. |
IC50& Target | |
体外研究 (In Vitro) | SAG (0.1 nM-100 μM; 30 h) induces firefly luciferase expression in Shh-LIGHT2 cells with an EC50of 3 nM and then inhibits expression at higher concentrations[1]. SAG (1-1000 nM; 1 h) competes for the binding of BODIPY-cyclopamine to Smo-expressing Cos-1 cells, yielding an apparent dissociation constant (Kd) of 59 nM for the SAG/Smo complex[1]. SAG (100 nM) inhibits the inhibitory effect of ShhN-induced pathway activation by Robotnikinin[2]. SAG (250 nM; 48 h) significantly increases SMO mRNA and protein expression in MDAMB231 cells[3]. SAG (250 nM; 24 and 48 h) increases CAXII mRNA expression in MDAMB231 cells at 24h in normoxic and hypoxic conditions in MDAMB231 cells[3]. SAG (250 nM; 24 h) increases MDAMB231 cells migration[3].

体内研究 (In Vivo) | SAG (1.0 mM) induces more osteogenesis mainly at the defect borders and a significant increase in BV/TV at the eight week timepoint in CD-1 mice[4]. SAG (15-20 mg/kg; i.p.) induces pre-axial polydactyly prevalently in a dose-dependent manner in mice[5].
Animal Model: | Pregnant C57BL/6J mice[5] | Dosage: | 15, 17, 20 mg/kg | Administration: | A single i.p. | Result: | Effective in ca. 80% of the embryos and increased Gli1 and Gli2 mRNA expression in the limb bud, with Gli1 mRNA being the most upregulated at the dose of 20 mg/kg. |
