Ozanimod (RPC-1063) (RPC1063) is a specific oral S1P Receptor 1 modulator. Ozanimod has been used in trials studying the treatment of Crohn's Disease, Ulcerative Colitis, Multiple Sclerosis, and Relapsing Multiple Sclerosis.

Tyloxapol (Triton WR1339) is a non-ionic liquid polymer utilized as a surfactant.

S1PR1 modulator 1 is a selective inhibitor of S1PR1, with a pIC50 of 7.6.

ASP-4058 is a selective, safe, and orally active second-generation agonist of sphingosine phosphate receptors 1 and 5 (S1P1 and S1P5).ASP-4058 ameliorates experimental autoimmune encephalomyelitis in mice.

LX-2931(LX-3305) is a sphingosine-1-phosphate cleavage enzyme (S1P) inhibitor for the treatment of rheumatoid arthritis.

SLP9101555 is a potent and selective sphingosine kinase 2 (SphK2) inhibitor with a Ki of 90 nM.SLP9101555 has a high affinity for SphK2, which is 200-fold higher than that of SphK1.SLP9101555 dramatically reduces extracellular S1P sphingosine 1-phosphate (S1P) levels.

Fingolimod hydrochloride (FTY720) , a novel immune modulator, is a sphingosine 1-phosphate (S1P) antagonist (IC50: 0.033 nM in K562 and NK cells).

SKI-178 is a sphingosine kinase 1 (SphK1) inhibitor with IC50 of 0.1-1.8 μM. It induces prolonged mitosis followed by apoptotic cell death through the intrinsic apoptotic cascade. The sustained activation of CDK1 during prolonged mitosis, mediated by SKI-178 leads to the simultaneous phosphorylation of the prosurvival Bcl-2 family members, Bcl-2 and Bcl-xl, as well as the phosphorylation and subsequent degradation of Mcl-1.
