Sphingosine-1-phosphate is an endogenous second messenger that involved in cell proliferation and survival and is a ligand for S1PR1 [1] [2].

Sphingosine-1-phosphate receptor 1 (S1PR1), also known as endothelial differentiation gene 1 (EDG1), is a G-protein-coupled receptor for sphingosine-1-phosphate (S1P) and is involved in regulating endothelial cell cytoskeletal structure, capillary-like network formation, migration and vascular maturation.

Sphingosine-1-phosphate is an endogenous second messenger and a ligand for S1PR1. In endothelial cells, S1P (1-20 µM) induced EDG-l-dependent morphogenesis. In HEK293EDG-1 cells, S1P bound to S1PR1 with Kd value of 8.1 nM in a time-dependent way. In cells transfected with EDG-l, S1P activated ERK-1 and ERK-2 via EDG-1. S1P existed in platelets and released through platelet activation [2]. In human embryonic kidney (HEK) cells, S1P significantly increased [Ca2+]i with EC50 value of 2 nM in a pertussis toxin-sensitive way and inhibited cAMP accumulation induced by forskolin. Also, S1P increased the binding of guanosine 5’-3-O-(thio)triphosphate to cell membranes. In guinea pig atrial myocytes, S1P at the extracellular face activated Gi protein-regulated inwardly rectifying potassium channels [3]. S1P inhibited programmed cell death mediated by ceramide [4].

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.
