Product Description

JTE 013 (JTE-013) is a novel potent and selective S1P2 (sphingosine-1-phosphate 2) antagonist with IC50 of 17.6 nM. It binds to the human and rat receptors with IC50 values of 17 and 22 nM, respectively, and with IC50 values >10 µM for human S1P1 and S1P3. It reverses the inhibitory effects of S1P2 signaling on cell migration of vascular ECs and smooth muscle cells. It also regulates endothelial tight junctions and barrier function in vitro. Blockage of S1P2 signaling by JTE-013 significantly enhances the effects of S1P on the increase of TEER, an in vitro measurement of endothelial integrity, as well as the formation of TJs in senescent ECs.

Biological Activity I Assay Protocols (From Reference)

ln Vitro

In vitro activity: JTE-013 reverses the inhibitory effects of S1P2 signaling on cell migration of vascular ECs and smooth muscle cells. It also regulates endothelial tight junctions and barrier function in vitro. Blockage of S1P2 signaling by JTE-013 significantly enhances the effects of S1P on the increase of TEER, an in vitro measurement of endothelial integrity, as well as the formation of TJs in senescent ECs

Kinase Assay: JTE 013 is a novel potent and selective S1P2 (sphingosine-1-phosphate 2) antagonist with IC50 of 17.6 nM. It binds to the human and rat receptors with IC50 values of 17 and 22 nM, respectively, and with IC50 values >10 µM for human S1P1 and S1P3. It reverses the inhibitory effects of S1P2 signaling on cell migration of vascular ECs and smooth muscle cells. It also regulates endothelial tight junctions and barrier function in vitro. Blockage of S1P2 signaling by JTE-013 significantly enhances the effects of S1P on the increase of TEER, an in vitro measurement of endothelial integrity, as well as the formation of TJs in senescent ECs.

Cell Assay: HUVECs preincubated with various concentrations of JTE-013 for 10 min are allowed to migrate for 4 h toward the lower chamber where the indicated concentrations of Sph-1-P are placed. The migrated cells on the lower side of the filter are fixed, stained, and counted.

ln Vivo

JTE-013 inhibition of S1P2 significantly inhibits microvascular permeability in an in vivo animal model. It modulates the responses of brain endothelium by inhibiting cerebrovascular permeability, the development of intracerebral heamorrhage, and neurovascular injury in an experimental model of stroke. JTE-013 reduced mast cell activation, airway infiltration, and the serum levels of histamine and several cytokines in vitro and in vivo studies. In a murine model, JTE-013 suppresses streptozotocin-induced blood glucose increases, pancreatic b cell apoptosis, and the incidence of diabetes. In a New Zealand obese diabetic mouse model under high-fat diet conditions, it protected pancreatic b cells. Treatment with JTE-013 also reduces plasma levels of IL-1b and IL-18 (endotoxin-induced inflammatory cytokines) in ApoE−/− mice and S1P2 gene deficiency reduces atherosclerosis. The compound offers a novel means of treating inflammatory disorders, such as, atherosclerosis and sepsis.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:

Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
Enter 25 into the Concentration (End) box and select the correct unit (mM)
Enter 25 into the Volume (End) box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
