Ceralifimod (ONO-4641) is a potent agonist for sphingosine 1-phosphate receptors 1 and 5 (EC50s: 27.3, 334 pM for human S1P receptor 1 and 5).

FTY720 (S)-Phosphate is an S1P receptor 1 (S1PR1) agonist. It is used in the research of acute inflammatory diseases such as acute lung injury.

TRV045 是一种选择性激活鞘氨醇-1-磷酸 (sphingosine-1-phosphate) 亚型 1 受体的激动剂，并且不会影响淋巴细胞运输。TRV045 显示出抗癫痫活性。

ML-178 是一种二氯苯，是鞘氨醇-1-磷酸受体4（S1PR4）的强效选择性激动剂，EC50 为 46 nM，在25 μM 的浓度下对其他 S1P 受体没有影响。

Lysosphingomyelin is an endogenous bioactive sphingolipid and a constituent of lipoproteins.1,2It is produced by the removal of the acyl group from sphingomyelin by a deacylase and acts as a precursor in the biosynthesis of sphingosine-1-phosphate . D-erythroLysosphingomyelin is an agonist of the S1P receptors S1P1, S1P2, and S1P3(EC50s = 167.7, 368.1, and 482.6 nM, respectively, for the human receptors).3It is also an agonist of the orphan receptor ovarian cancer G protein-coupled receptor 1 (ORG1) that induces calcium accumulation in cells overexpressing OGR1 (EC50= ~35 nM).4Levels of D-erythrolysosphingomyelin are increased in skin isolated from patients with atopic dermatitis, as well as postmortem brain from patients with Niemann-Pick disease type A, but not type B.2,5L-threolysosphingomyelin is also an S1P1-3agonist (EC50s = 19.3, 131.8, and 313.3 nM, respectively).3This product is a mixture of D-erythroand L-threolysosphingomyelin.

FTY720 is a derivative of ISP-1 (myriocin), a fungal metabolite of the Chinese herb Iscaria sinclarii as well as a structural analog of sphingosine. It is a novel immune modulator that prolongs allograft transplant survival in numerous models by inhibiting lymphocyte emigration from lymphoid organs. FTY720 is phosphorylated by sphingosine kinase, which then acts as a potent agonist at four of the sphingosine-1-phosphate (S1P) receptors (S1P1, S1P3, S1P4, and S1P5). Down-regulation of S1P1 receptors on T and B lymphocytes by FTY720 results in defective egress of these cells from spleen, lymph nodes, and Peyer's patch. azido-FTY720 is a highly photoreactive analog of FTY720 that can be used to identify receptor binding sites for this ligand.
