Biological Activity

Description SB 4 is a potent and selective agonist of bone morphogenetic protein 4 (BMP4) signaling with EC50 of 74 nM. SB 4 enhances canonical BMP signaling and activates SMAD-1/5/9 phosphorylation.
Targets
BMP4 [1]
(Cell-free assay)
74 nM(EC50)
In vitro
In vitro

BMP signaling agonist SB 4 induces phosphorylated SMAD-1/5/9 in a dose-dependent manner in PRECs cells under serum-starved conitions. SB 4 enhances the efficacy of signaling at each concentration of rhBMP4 tested. SB 4 increases BRE-luc expression 2-fold at 0.4 ng/ml of rhBMP4.[1]
Cell Research 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.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
