Attached as an end group to a moiety containing an aliphatic group, an alicyclic group, an aromatic group, and / or a heterocyclic group It is a functional group that is

[0005] S1P receptor modulators are those that bind to one or more sphingosine-1 phosphate receptors ( It is a compound that acts as an agonist for S1P1 to S1P8. It binds to S1P receptors. The agonists that bind to the Gα-GTP and Gβγ-GTP are, for example, intracellular heterotrimers. dissociation of mer-G proteins and / or increased phosphorylation of agonist-bound receptors and This can result in activation of downstream signaling pathways / kinases.

[0006] The binding affinity of S1P receptor modulators to individual human S1P receptors was evaluated using the following assay: It can be determined by Say: The S1P receptor modulator activity of the compounds was determined by measuring the S1P receptors S1P1, S1P2, and S The appropriate human S1P receptors are stably expressed and tested for S1P3, S1P4 and S1P5. Membrane proteins prepared from transfected CHO or RH7777 cells expressing Compound-induced GTP[γ- 35 S] binding to determine functional receptor activity. The assay used is SPA (scintillation proximity based) Briefly, compounds dissolved in DMSO were serially diluted and assayed for S1P receptor activation. Presence of membrane proteins was confirmed by buffering with 50 mM Hepes, 100 mM NaCl, 10 mM MgCl 2, 10 μM GDP, 0.1% lipid-free BSA and 0.2 nM GTP[γ- 3 5 S] (1200 Ci / mmol) was added to immobilized SPA beads (Amersham-Pharmacia). (10-20 μg / well) in a 96-well microtiter plate. After incubation for 1 min, unbound GTP[γ- 35 The membrane is separated by centrifugation. bound GTP[γ- 35 The luminescence of SPA beads triggered by [S] was measured using TOPcount Quantitation was performed using a triad (Packard). 50 Using standard curve fitting software In this assay, S1P receptor modulators are Preferably, it has a binding affinity to the S1P receptor of <50 nM.

[0007] Desirable S1P receptor modulators may, for example, have lymphocyte homing properties in addition to S1P binding properties. Compounds that promote the immune-regulating properties of the immune system, e.g., secondary lymphoid tissues, without causing systemic immunosuppression. Induce lymphopenia by redistribution (preferably reversible) of lymphocytes from the circulation to the Compound. Sequesters naive cells; CD4 and CD8 T cells and B cells from blood stimulates the cells to migrate to lymph nodes (LNs) and Peyer's patches (PPs).

[0008] Lymphocyte homing properties may be measured in the blood lymphocyte depletion assay described below. S1P receptor modulators or vehicle were administered orally by gavage to rats. Tail blood was taken on day -1 to monitor blood levels and baseline individual values. and tail blood was collected at 2, 6, 24, 48 and 72 hours after application. In this assay, an S1P receptor agonist or modulator may be used, for example Reduces peripheral blood lymphocytes by 50% when administered at <20mg / kg.

[0038] In vivo: Relapsing experimental autoimmune encephalomyelitis (EAE) The disease was induced in female Lewis rats by injecting mofetil emulsified in complete Freund's adjuvant. The disease was induced by immunization with rat spinal cord tissue, which produced an acute disease by day 11. This is followed by a near-complete remission around day 16, followed by a relapse around day 26. On the sixth day, the rats were deeply anesthetized with isoflurane (3%, 20 L / min), and the thorax was excised and the heart was The left ventricle of the liver was perfused with rinsing solution (NaCl 0.9%, 250,000 A winged infusion set was attached to an airtight pressurized syringe containing 0.0 U / l heparin, 35°C. The right atrium was perforated with a 19-gauge needle from a thoracic ventricle catheter (SV-19BLK; Termudo, Elkton, MD). A hole is drilled to inject irrigation fluid under a precisely controlled pressure of 120 mmHg. This was continued for 5 min (at a constant rate of 20 ml / min) followed by the addition of pre-fixation solution (P Add 2% performaldehyde in BS (35°C). Finally, add up to 30 ml of polyurethane. Polypropylene resin (PUII4; Vasqtec, Zuerich, Switzerland) was injected at the same rate. After 48 h, the Lipid-filled brains and spinal cords were removed from the animals and dissociated in 7.5% KOH at 50°C for 24 hours. The casts were then washed thoroughly with distilled water and After storage in water, they are dried by freeze-drying. These vascular casts are then The results will be quantified using computed tomography.

[0039] In this assay, an S1P1 receptor modulator, e.g., Compound A, is administered to an animal: When administered orally at 0.1 to 20 mg / kg, it significantly blocks disease-associated angiogenesis. The hydrochloride salt of Compound A completely blocked disease-associated angiogenesis and was administered orally at 0.3 mg / kg. Compound A hydrochloride was administered at 0.3 mg / kg once every 2 or 3 days. Similar effects are obtained when administered orally once or once weekly.
