Ozanimod CAS 1306760-87-1
Selective S1P1 / S1P5 Receptor Modulator
Ozanimod (development code RPC1063; marketed as Zeposia) is an orally active, next-generation sphingosine-1-phosphate receptor modulator with an EC50 of approximately 0.41 nM at human S1P1 and 11 nM at S1P5, and minimal activity at S1P2, S1P3 or S1P4. It functions as a functional antagonist: sustained S1P1 internalisation renders lymphocytes blind to the egress gradient, sequestering them in lymph nodes and cutting immune infiltration into the central nervous system and intestinal mucosa. Approved for relapsing multiple sclerosis and moderately to severely active ulcerative colitis.

Receptor Target Profile & S1P Subtype Selectivity
Five G-protein-coupled receptors read the sphingosine-1-phosphate signal; ozanimod deliberately engages only the two that govern lymphocyte egress and oligodendrocyte biology
Ozanimod Mechanism of Action: Agonism That Behaves Like Antagonism
How persistent S1P1 activation traps lymphocytes in lymph nodes and starves inflamed tissue of autoreactive cells
The S1P Egress Gradient
Sphingosine-1-phosphate is abundant in blood and lymph but kept low inside lymphoid tissue by S1P lyase. Lymphocytes sense this gradient through surface S1P1 and use it as the directional cue to exit lymph nodes into the circulation.
High-Affinity S1P1 Engagement
Ozanimod binds S1P1 as a full agonist with an EC50 of about 0.41 nM, triggering Gi/o signalling and β-arrestin recruitment. Its selectivity for S1P1 and S1P5 leaves S1P3-mediated cardiac and vascular effects largely untouched.
Receptor Internalisation & Degradation
Unlike the natural ligand, which allows rapid recycling, ozanimod drives sustained β-arrestin-dependent internalisation, ubiquitination and proteasomal degradation of S1P1 — converting an agonist into a durable functional antagonist.
Lymphocyte Sequestration
Without surface S1P1, the lymphocyte cannot read the egress gradient and remains trapped in the lymph node. Circulating naive and central memory T and B cells fall by roughly 50-65%, while effector memory and tissue-resident immunity is comparatively preserved.
Reduced Tissue Infiltration
With fewer autoreactive lymphocytes in circulation, trafficking across the blood-brain barrier into CNS lesions and into inflamed colonic mucosa falls. This is the shared basis of efficacy in relapsing multiple sclerosis and in ulcerative colitis.
Central S1P5 Component
S1P5 is expressed on oligodendrocytes, oligodendrocyte precursors and astrocytes. Because ozanimod and its major active metabolite CC112273 are CNS-penetrant, a direct glial contribution to remyelination and neuroprotection is an active research question.
Research Applications of the S1P1/S1P5 Modulator Ozanimod
A best-in-class chemical tool for lymphocyte trafficking, autoimmune inflammation and sphingolipid GPCR pharmacology
Relapsing-Remitting Multiple Sclerosis
The RADIANCE and SUNBEAM phase 3 programmes established ozanimod against interferon beta-1a on annualised relapse rate and MRI lesion burden. In the laboratory it is the reference S1P modulator in experimental autoimmune encephalomyelitis, cuprizone demyelination and blood-brain-barrier trafficking models.
NeuroimmunologyUlcerative Colitis & IBD
TOUCHSTONE and the pivotal TRUE NORTH trial demonstrated induction and maintenance of clinical remission in moderately to severely active ulcerative colitis. Widely used in DSS colitis, T-cell transfer colitis and mucosal-healing studies as an oral alternative to anti-integrin biologics.
GastroenterologyS1P Receptor Pharmacology & GPCR Biology
An essential selectivity benchmark in S1P1-S1P5 panels: GTPγS binding, cAMP inhibition, β-arrestin recruitment (PathHunter/Tango), receptor internalisation imaging and BRET-based conformational assays. Frequently paired with fingolimod-phosphate and siponimod as comparators.
Receptor PharmacologyLymphocyte Trafficking & Egress
Used to acutely and reversibly block lymph node egress in vivo, allowing researchers to separate the contribution of newly recruited circulating lymphocytes from that of tissue-resident populations in infection, transplantation and tumour immunology models.
Immune Cell TraffickingCrohn's Disease & Mucosal Immunology
Explored beyond ulcerative colitis into Crohn's disease and other mucosal inflammatory conditions, where reducing lymphocyte recruitment to the gut wall is the therapeutic goal. Useful for studying gut-homing integrin biology and epithelial barrier restoration.
Mucosal ImmunityVascular Barrier & Cardiac Safety Pharmacology
S1P1 maintains endothelial adherens junctions while S1P3 mediates bradycardia. Ozanimod's S1P3-sparing profile makes it the standard tool for dissecting which S1P subtype drives which vascular or cardiac phenotype in safety pharmacology research.
Safety PharmacologyRemyelination & Oligodendrocyte Biology
Because S1P5 is expressed on oligodendrocyte lineage cells and ozanimod is CNS-penetrant, it is applied in oligodendrocyte precursor differentiation assays, myelin sheath formation co-cultures and neuroprotection paradigms.
Glial BiologyMetabolism, DDI & Active-Metabolite Research
Ozanimod is a rich case study in complex metabolism: alcohol/aldehyde dehydrogenases, MAO-B, CYP3A4 and gut microflora generate the major circulating active metabolites CC112273 and CC1084037, with CC112273 cleared by CYP2C8 — the basis of its rifampin, gemfibrozil and MAO-inhibitor interactions.
DMPK / ADMEBroader Autoimmune & Inflammatory Models
Applied across psoriasis, rheumatoid arthritis, lupus, graft-versus-host disease, transplant rejection and acute lung injury models where lymphocyte egress blockade or endothelial barrier stabilisation is the mechanistic hypothesis under test.
