• 产品描述： SB 4 是一种 bone morphogenetic protein 4 (BMP4) signaling 的有效的选择性激动剂，其EC50值为74 nM。SB 4可增强经典的BMP信号传导并激活 SMAD-1/5/9 磷酸化

• 靶点： BMP4(Cell-free assay):74 nM(EC50);TGF-beta/Smad

• 体外研究：
  BMP signaling agonist sb4 (0.05 μM-1 μM; 24 hours) induces phosphorylated SMAD-1/5/9 in a dose-dependent manner in PRECs cells under serum-starved conitions.
  BMP signaling agonist sb4 (1 μM; 0-60 mins) enhances the efficacy of signaling at each concentration of rhBMP4 tested. This effect is most pronounced at low concentrations of rhBMP4, whereby sb4 increases BRE-luc expression 2-fold at 0.4 ng/ml of rhBMP4.

• 细胞实验： Cell lines: Primary mouse kidney epithelial cells (PRECs) Concentrations: 0.05 μM-1 μM Incubation Time: 0-1 h, 24 h Method: The BRE-Luc cells are stimulated with 2 ng/ml rhBMP4 for 1 h, after which the media are removed and replaced with fresh media containing either DMSO or 1 μm SB 4. p-SMAD-1/5/9 levels are then examined after 0, 5, 15, 30, 45, and 60 min of SB 4 treatment and compared with DMSO controls.
