Cat.No. 5833 - Ex 26 | C28H28ClFN2O3 | CAS No. 1233332-37-0
Description: Potent and selective S1P1 receptor antagonist
Chemical Name: 1-[[[5'-[[1-(4-Chloro-3-methylphenyl)ethyl]amino]-2'-fluoro-3,5-dimethyl[1,1'-biphenyl]-4-yl]carbonyl]amino]-cyclopropanecarboxylic acid
Purity: ≥98% (HPLC)

Biological Activity

Potent and selective S1P1 receptor antagonist (IC50 = 0.93 nM). Exhibits > 3,000-fold selectivity for S1P1 over S1P2, S1P3, S1P4 and S1P5. Induces lymphocyte sequestration in peripheral lymph nodes and upregulates S1P1 receptor expression. Reduces disease severity in mice with EAE. Increases IFN-α production in stimulated dendritic cells in vivo.

Preparing Stock Solutions

The following data is based on the product molecular weight 494.98. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.02 mL 10.1 mL 20.2 mL
5 mM 0.4 mL 2.02 mL 4.04 mL
10 mM 0.2 mL 1.01 mL 2.02 mL
50 mM 0.04 mL 0.2 mL 0.4 mL
