Definitions
- the present invention relates to a new use for a sphingosine-1-phosphate (S1P) receptor agonist, particularly in the treatment of heart diseases.
- S1P sphingosine-1-phosphate
- S1P receptor agonists are accelerating lymphocyte homing agents which elicit a lymphopenia resulting from a re-distribution, preferably reversible, of lymphocytes from circulation to secondary lymphatic tissue, without evoking a generalized immunosuppression.

Abstract
The invention relates to the use of sphingosine-1-phosphate receptor agonist in the treatment of heart diseases.
Description
- The present invention relates to a new use for a sphingosine-1-phosphate (S1P) receptor agonist, particularly in the treatment of heart diseases.
- S1P receptor agonists are accelerating lymphocyte homing agents which elicit a lymphopenia resulting from a re-distribution, preferably reversible, of lymphocytes from circulation to secondary lymphatic tissue, without evoking a generalized immunosuppression. Naïve cells are sequestered; CD4 and CD8 T-cells and B-cells from the blood are stimulated to migrate into lymph nodes (LN) and Peyer's patches (PP), and thus for example infiltration of cells into transplanted organs is inhibited.
- S1P receptor agonists are typically sphingosine analogues, such as 2-substituted 2-amino-propane-1,3-diol or 2-amino-propanol derivatives, e.g. a compound comprising a group of formula X
- wherein
Z is H; C1-6alkyl; C2-6alkenyl; C2-6alkynyl; phenyl; phenyl substituted by OH; C1-6alkyl substituted by 1 to 3 substituents selected from the group consisting of halogen, C3-8cyclo-alkyl, phenyl and phenyl substituted by OH; or CH2—R4z wherein R4z is OH, acyloxy or a residue of formula (a) - wherein Z1 is a direct bond or O, preferably O; each of R5z, and R6z, independently, is H, or C1-4alkyl optionally substituted by 1, 2 or 3 halogen atoms;
R1z is OH, acyloxy or a residue of formula (a); and each of R2z and R3z, independently, is H, C1-4alkyl or acyl. - Group of formula X is a functional group attached as a terminal group to a moiety which may be hydrophilic or lipophilic and comprise one or more aliphatic, alicyclic, aromatic and/or heterocyclic residues, to the extent that the resulting molecule wherein at least one of Z and R1z is or comprises a residue of formula (a), signals as an agonist at one of more sphingosine-1-phosphate receptor.
- S1P receptor agonists are compounds which signal as agonists at one or more sphingosine-1 phosphate receptors, e.g. S1P1 to S1P8. Agonist binding to a S1P receptor may e.g. result in dissociation of intracellular heterotrimeric G-proteins into Gα-GTP and Gβγ-GTP, and/or increased phosphorylation of the agonist-occupied receptor and activation of downstream signaling pathways/kinases. The binding affinity of S1P receptor agonists may be measured as described at paragraph I. below. Preferred S1P receptor agonists are those targeting e.g. S1P2 and/or S1P3.
- Examples of appropriate S1P receptor agonists are, for example
-

- The S1P receptor agonists have, on the basis of observed activity, e.g. homing of lymphocytes, e.g. as described in EP627406A1 or U.S. Pat. No. 6,004,565, been found to be useful e.g. as immunosuppressant, e.g. In the treatment of acute allograft rejection.
- It has now been found that S1P receptor agonists have a beneficial effect in heart diseases, e.g. in chronic heart failure, congestive heart failure, complications of cardiovascular surgery, peri-operative hypertension, unstable angina or acute myocardial infarction.
- Chronic heart failure is a clinical syndrome characterized by distinctive symptoms and signs resulting from disturbances in cardiac output, e.g. Inadequate for the body's needs. It is often associated with other changes such as cardiac hypertrophy and myocardial ischemia. Congestive heart failure (CHF), or heart failure, is a condition in which the heart cannot pump enough blood to the body's other organs. As blood flow out of the heart slows, blood returning to the heart through the veins backs up, causing congestion in the tissues.

- 1.1 A method for treating chronic heart failure in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;
- 1.2 A method for improving heart energy efficiency and/or reducing its oxygen needs in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;
- 1.3 A method for improving cardiac output in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;
- 1.4 A method for treating arrhythmia or tachyarrhythmia, e.g. atrial fibrillation, atrial flutter or sinus ventricular tachycardia, in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;
- 1.5 A method for treating congestive heart failure in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;
- The method of the invention is also appropriate for patients with acutely decompensated congestive heart failure and patients with pre-existing arrythmias.
- 1.6 A method for treating complications of cardiovascular surgery, e.g. peri-operative hypertension, in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;
- 1.7 A method for treating unstable angina in a subject in need thereof comprising administering to said subject a therapeutically effective amount of a S1P receptor agonist;

- Utility of the S1P receptor agonists, e.g. in the treatment of heart diseases, as hereinabove specified, may be demonstrated in animal test methods as well as in clinic, for example in accordance with the methods hereinafter described.
- Transient Transfection of Human S1P Receptors into HEK293 Cells
- S1P receptors and Gi proteins are cloned, and equal amounts of 4 cDNAs for the S1P receptor, Gi-α, Gi-β and Gi-γ are mixed and used to transfect monolayers of HEK293 cells using the calcium phosphate precipitate method (M. Wigler et al, Cell. 1977; 11; 223 and D S. Im et al., Mol. Pharmacol. 2000; 57; 753). Briefly, a DNA mixture containing 25 μg of DNA and 0.25 M CaCl is added to HEPES-buffered 2 mM Na2HPO4. Subconfluent monolayers of HEK293 cells are poisoned with 25 mM chloroquine, and the DNA precipitate is then applied to the cells. After 4 h, the monolayers are washed with phosphate-buffered saline and refed media (90% 1:1 Dulbecco's modified essential media (DMEM):F-12+10% fetal bovine serum). The cells are harvested 48-72 h after addition of the DNA by scraping in HME buffer (in mM: 20 HEPES, 5 MgCl2, 1 EDTA, pH 7.4) containing 10% sucrose on ice, and disrupted using a Dounce homogenizer. After centrifugation at 800×g, the supernatant is diluted with HME without sucrose and centrifuged at 100,000×g for 1 h. The resulting pellet is rehomogenized and centrifuged a second hour at 100,000×g. This crude membrane pellet is resuspended in HME with sucrose, aliquoted, and snap-frozen by immersion in liquid nitrogen. The membranes are stored at 70° C. Protein concentration is determined spectroscopically by Bradford protein assay.
- GTPγS binding experiments are performed as described by D S. Im et al., Mol. Pharmacol. 2000; 57:753. Ligand-mediated GTPγS binding to G-proteins is measured in GTP binding buffer (in mM: 50 HEPES, 100 NaCl, 10 MgCl2, pH 7.5) using 25 μg of a membrane preparation from transiently transfected HEK293 cells. Ligand is added to membranes in the presence of 10 μM GDP and 0.1 nM [35S]GTPγS (1200 Ci/mmol) and incubated at 30° C. for 30 min. Bound GTPγS is separated from unbound using the Brandel harvester (Gaithersburg, Md.) and counted with a liquid scintillation counter.
- The effect of a S1P receptor agonist, e.g. a compound of formula I on chronic heart failure is tested in rabbits where heart failure is induced as a consequence of a large myocardial infarction (R P. H of et al. J. Cardiovasc. Pharmacol., 1991, 18, 361-368). The changes of atrial natriuretic factor or baroflex sensitivity are a reliable indicator of the status of the heart failure in this animal model. When administered i.v. at a dose of from 0.1 to 10 mg/kg, a S1P receptor agonist, e.g. the compounds of formula I, e.g. Compound A, have a beneficial effect on the heart failure.
- Patients with class IV congestive heart failure are selected: they have elevated intracardiac filling pressures (orthopnea, abdominal discomfort attributed to hepato-splenic congestion, peripheral edema, ascites, rales and jugular venous distension) and inadequate peripheral perfusion. Patients receive a daily dose of the S1P receptor agonist to be tested, e.g. Compound A in free form or a pharmaceutically acceptable salt thereof, e.g. orally, during 2 or 4 weeks or 3 months. The dose may be escalated if necessary. Patients are followed-up for 6 months. Following data are collected during hospitalization and the 6 month follow-up: blood pressure, weight, electrocardiogram, echocardiogram, serum electrolytes, natriuretic hormone profile and exercise stress tests.
- A beneficial effect is observed.
- Daily dosages required in practicing the method of the present invention will vary depending upon, for example, the compound used, the host, the mode of administration, the severity of the condition to be treated. A preferred daily dosage range is about from 0.03 to 2.5 mg/kg per day as a single dose or in divided doses. Suitable daily dosages for patients are on the order of from e.g. 0.5 to 50 mg p.o. Suitable unit dosage forms for oral administration comprise from ca. 0.1 to 25 mg active ingredient, e.g. FTY720, e.g. in hydrochloride form, together with one or more pharmaceutically acceptable diluents or carriers therefor. As an alternative, the S1P receptor agonist may also be administered twice or three times a week, e.g. at a dosage as indicated above.
- The S1P receptor agonist may be administered by any conventional route, in particular enterally, e.g. orally, for example in the form of solutions for drinking, tablets or capsules or parenterally, for example in the form of injectable solutions or suspensions. Pharmaceutical compositions comprising a S1P receptor agonist, e.g. a compound of formula I may be manufactured in conventional manner, e.g. as described in EP-A1-627,406 or in EP-A1-1,002,792.
- The S1P receptor agonists may be administered as the sole ingredient or together with other drugs, e.g. an angiotensin converting enzyme inhibitor, e.g. benazepril, captopril, quinapril, ramipril, enalapril, linisopril or moexipril, an angiotensin II receptor antagonist, e.g. valsartan, losartan, irbesartan, eprosartan, forasartan, olmesartan, ripisartan, saprisartan, candesartan, tasosartan or telmisartan, a synthetic form of B-type natriuretic peptide (BNP) or other human B-type natriuretic peptide, e.g. nesiritide, other drugs used in patients with heart failure, e.g. digoxin or digitalis preparations, a β-blocker, e.g. propanolol, atenolol, a β-adrenergic receptor agonist, e.g. salbutamol, an α-2 receptor agonist, e.g. dexmetomidine, a calcium antagonist, e.g. cilnidipine, or a diuretic, e.g. hydrochlorothiazide or spironolactone.
- Where the S1P receptor agonists are administered in conjunction with other drugs, dosages of the co-administered compound will of course vary depending on the type of co-drug employed, on the specific drug employed, on the condition to be treated, and so forth. The terms “co-administration” or “combined administration” or the like as utilized herein are meant to encompass administration of the selected therapeutic agents to a single patient, and are intended to Include treatment regimens in which the agents are not necessarily administered by the same route of administration or at the same time.
- In accordance with the foregoing the present invention provides in a yet further aspect:
- 5. A pharmaceutical combination comprising a) a first agent which is a S1P receptor agonist, e.g. a compound of formula I, e.g. FTY720, or Compound B or C or a compound of formula V or VIII, or a phosphate thereof, or a pharmaceutically acceptable salt thereof, and b) a co-agent, e.g. a second drug agent as defined above.
- 6. A method as defined above comprising co-administration, e.g. concomitantly or in sequence, of a therapeutically effective amount of a S1P receptor agonist, e.g. a compound of formula I, e.g. FTY720, or Compound B or C, or a compound of formula V or VIII, or a phosphate thereof, or a pharmaceutically acceptable salt thereof, and a second drug substance, e.g. as indicated above.
- S1P receptor agonists are well tolerated at dosages required for use in accordance with the present invention. For example, FTY720 has an acute LD50>10 mg/kg p.o. in rats and monkeys.
- The administration of a pharmaceutical combination of the invention results in a beneficial effect, e.g. a synergistic therapeutic effect, less side-effects or an improved quality of life compared to a monotherapy.
