Provisional Patent Application Serial No. 60/646436, filed January 21, 2005. This application relates to PCT application No. PCT/US05/28914, filed August 12, 2005.

The entire contents of each of the aforementioned patent applications are hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

Th e sphingosin e-1 -phosphate (SlP) receptors 1-5 constitute a family of seven transmembrane G-protein coupled receptors. These receptors, referred to as SIPl to S !P5, are activated via binding by sphingosin e-1 -phosphate, which is produced by the sphingosine kinase-catalyzed phosphorylation of sphingosine. SlP receptors are cell surface receptors involved in a variety of cellular processes, including cell proliferation and differentiation, cell survival, cell invasion, lymphocyte trafficking, and cell migration. Sphingosine-1 -phosphate is found in plasma and a variety of other tissues, and exerts autocrine and paracrine effects, including regulating the secretion of growth factors Administration of SlP to an animal results in sequestration of lymphocytes into the lymph nodes and Peyers patches without causing lymphocyte depletion. This activity, which is of potential utility in treating diseases or conditions associated with inappropriate immune response, including transplant rejection and autoimmu ne diseases, is believed to proceed via activation of the SlPl receptor. Administration of SlP in vivo also has negative effects, including hypotension and bradycardia, which are believed to be due to signaling through one or more of the other S I P receptors, i.e. S 1P2 to S 1P5. Accordingly, there is a great need in the art for compounds which are potent and selective agonists of th e SlPl receptor.

SUMMARY OF THE INVENTION

BRIEF DESCRIPTION OF THE DRAWING

Figure 1 is a graph showing the results of the lymphopenia assay for certain compounds of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The compounds provided by the present invention are modulators of the S lPl receptor, e.g., agonists or antagonists of the S lPl receptor. In particular embodiments, the compounds are selective agonists of the SlPl receptor, e.g., containing a selectivity enhancing moiety (SEM). In addition to the SlPl modulator compounds, th e invention also provides pharmaceutical compositions comprising these compounds and methods of using these compounds for treating a condition associated with an inappropriate immune response, such as transplant rejection or an autoimmun e disease.

Definitions

The term "selectivity enhancing moiety (SEM)," as used herein, refers to on e or more moieties that provide an enhancement in th e selectivity of the compound to which they are attached for the SlPl receptor, as compared to the compound not containing the moiety or moieties, The SEM confers selectivity to the compound to which it is attached for the SlPl receptor as compared to, for example, the S1P2 to S 1P5 receptors. Th e enhancement conferred to a compound by the SEM may be measured by, for example, determining the binding specificity of a compou nd for the S IPl receptor and on e or more of the other S lP receptors or by monitoring the

- 14 - SUBSTTTTJTE SHEET (RULE 26)

phosphorylation of a compound, e.g., in vivo, wherein enhancement conferred to a compound by the SEM may be in the form of increased binding and/or increased phosphorylation. Without wishing to be boun d by theory, it is believed that the enhancement of th e selectivity for the SlPl receptor may be the result of an alteration in the overall conformation of the compound (e.g., due to local or global conformational changes); the electronic properties of the compound (e.g. , resulting in altered binding properties locally or globally); or the Iypophilicity of the compound. In certain embodiments, the SEM is selected from, but not limited to, a group consisting of halogen (e.g., F, Cl, and Br), cyano, straight chain or branch ed Cj -Cs- alkyl, straight chain or branch ed C 1 -C 6 -alkoxy, straight chain or branch ed halo-C 1 -C 6 - alkyl (e.g., CF3), straight chain or branched halo-C 1 -C 6 -alkoxy, C 1 -C 6 -alkoxy-C 1 -C 6 - alkyl, hydroxyl-d-Q-alkyl, carboxy-C 1 -C 6 -alkyl, C 1 -C 6 -alkyJ-SO 2 Or N(R)R', wherein R and R' are each independently hydrogen, straight chain or branched C 1 -C 6 - alkyl, straight chain or branch ed C 1 -Q-alkoxy, straight chain or branched halo-C 1 -Cή- alkyl, straight chain or branched halo-C 1 -Cή-alkoxy, Cj-Cβ-alkoxy-C 1 -C 6 -alkyl, hydroxyl-C 1 -C 6 -alkyl, carboxy-C 1 -C 6 -alkyl or C 1 -C 6 -alkyi-SCh ; alkylcarbonyl, thioether, aikylsulfonyl, alkylcarbonylamino, alkylaminocarbσnyl, alkyloxycarbonyl, alkylcarbonyloxy, substituted or unsubstituted aromatic , substituted or unsubstituted heteroaromatic, any straight chain or branched alkylene, straight chain or branched alkenyl, straight chain or branch ed alkynyl, straight chain or branch ed alkenylene, arylalkyl, alkylaryl, alkylene-aryl, alkenyl-aryl, alkynyl-aryl or alkenylen e-aryl group.

The proper fluidity can be maintained, for example, by th e use of a coating such as lecithin, by the maintenance of the required particle size in th e case of dispersion and by th e use of surfactants. Prevention of the action of

microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabeπs, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, or sodium chloride in the composition. Prolonged absorption of th e injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

Sterile injectable solutions can be prepared by incorporating th e compound of the invention in th e required amount in an appropriate solvent with one or a combination of the ingredients enumerated above, as needed, followed by filtered sterilization. Gen erally, dispersions are prepared by incorporating th e compound into a steriie vehicle which contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of steriie powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze-drying which yields a powder of the compound plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Oral compositions generally include an inert diluent or an edible carrier. They can be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the compound of the invention can be incorporated with excipients and used in the form of tablets, troches, or capsules. Oral compositions can also include an enteric coating. Oral compositions can also be prepared using a fluid carrier for use as a mouthwash, wherein the compound in the fluid carrier is applied orally and swished and expectorated or swallowed. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. Th e tablets, pills, capsules, troch es and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystallin e cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as aiginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring,

For administration by inhalation, the compounds of the invention are delivered in the form of an aerosol spray from a pressured container or dispenser which contains a suitable propelfant, e.g., a gas such as carbon dioxide, or a nebulizer.

EXAMPLES

Example 1 Synth esis of Phenylamtde Compounds with Alkoxy Tail Group

Certain of the target compounds were synth esized using either the method illustrated in Scheme 1 or the method illustrated in Scheme 2, In Scheme 1, allcylation of the hydroxy! group of a substituted aminophenoi is achieved using alky] bromide and a catalytic amount of NaI in the presence of either CS2CO3 in DMF (60 0 C) or KO'Bu in acetone (50 0 C). The amino group of th e desired intermediate is then acylated with Boc-protected amino acid using either N-ethylcarbodiimide (EDC), 1- hydroxybenzotriazole (HOBt), and N,N-diisopropylethylamine (DIPEA) in CH 2 Cb or lAS-tetramethyluroniurn h exafluorophosphate (HATU) and DIPEA in DMP. The final compound was obtained in good yields from Boc deprotection of the later intermediate with 30% trifluoroacetic acid (TFA) in CH2CI2. Scheme 2 provides an alternative approach to synthesis of the desired final compound in which the amino group of the aminoph enoi is acylated first, followed by alkylation of th e hydroxy! residue.

Example 2

Synth esis of Ph enylimidazole Compounds with Alkoxy Tail Group

The desired compounds were synth esized as described in Scheme 3. Substituted phenols were alkylated with the appropriate alkyl bromide using KO'Bu in acetone and a catalytic amount of NaI at 50 0 C, or in a microwave at 80 0 C using KO'Bu in THF. Friedel-Crafts acylation of the corresponding phenyl ether provides the desired bromoacetoph enone precursor. Reaction of the bromoacetophenone with an amino acid gave the amino acid ester as an intermediate which, upon intramolecular cyclization in the presence of excess ammonium acetate, provided the desired phenylimidazole. The phenylimidazole was either deprotected to remove the Boc group using 30% TFA in CH 2 Ch, or was phosphorylated as illustrated in Scheme 4.

DMF

General procedure for synthesis of substituted biaryl ethonol:

To a DMF solution of the 4-(haloary!oxy)-aniiine (] .0 equiv) and substituted aryl boronic acid in a microwave tube, was added Pd(OAc) 2 (0.1 equiv), triphenyl phosphine (0,2 equiv), cesium carbonate (1.0-1.5 equiv) and TBAC (0, 1 equiv). The reaction was then sealed and heated at 50-70 0 C for 3-18 hours using an oil bath. The reaction mixture was diluted with EtOAc (25 mL), washed with water (2 x 10 mL) and th en brine (1 x 10 mL). The organic layer was then dried over MgSO4, and th en solvent removed under reduced pressure. Th e crude product was purified using th e Combi-Flash silica gel column chromatography, using a Hexane/EtOAc gradient.

Synth esis of Plienylimidazole/Ph enyloxazole Analogs

General method for synthesis of ph enylimidazole/ph enyloxazole

The gen eral approach for synth esis of various ph enylazole compounds 5 is described in Scheme 18. Reaction of desired alcohol with substituted 4- fluoroacetophenone 1 at 60-70 0 C afforded the eth er-acetophenone intermediate 2. The eth er-acetoph enone 2 was then converted to the bromo-acetophenone using CuBr2. Reaction of the bromo-acetophenone with Boc-α-MeSer afforded the desired ester 3 which was then converted to the azole precursor 4 using AcONH). Deprotection of th e Boc group provided the TFA salt of the final compound 5 in good yield. The final compounds were then isolated either as TFA or HCl salts.

Example 12 Lymphopenia Assay

Several of the compounds described herein were evaluated for the ability to induce lymphopenia in mice. Male C57B1/6 mice were divided into groups of three. A control group received the 3% BSA vehicle only. The other groups received a single dose of either a specified dose of test compound in vehicle administered orally (PO). After 6 hours, the mice were anesthesized with isoflurane and approximately 250 μL of blood was removed from the retroorbital sinus and collected in an EDTA microtainer, mixed with an anticoagulant and placed on a tilt table until complete blood count (CBC) analysis. Figure 1 shows the results of the analysis for total lymphocyte count for different doses of compounds 10, 13 and 14, The results show that all three compounds, when dosed orally, are able to induce lymphopenia in mice relative to control,

Binding to SlPl or S1P3 Receptors

The ability of several of the compounds described herein to bind to the SIPl or S1P3 receptor was also tested as follows. For the membrane preparation, plasmid DNA was transfected into HEK 293 T cells using the FuGENE 6 transfection protocol (publicly available by Roche). Briefly, subconfluent monolayers of HEK 293 T cells were transfected with the DNA mixture containing FuGENE 6 (using a 1 :3 ratio). The dishes containing the cells were th en placed in a tissue culture incubator (5% CO 2 , 37°C). The cells were harvested 48 hours after addition of the DNA by scraping in HME buffer (in mM: 20 HEPES 5 5 MgCl 2 , 1 EDTA, pH 7.4, 1 mM PMSF) containing 10% sucrose on ice, and disrupted using a Dounce homogenizer. After centrifugati on at 800 * g, the supernatant was diluted with HME without sucrose and centrifuged at 17,000 x g for 1 hour. This crude membrane pellet was resuspended in HME with sucrose, aliquoted, and snap-frozen by immersion in liquid nitrogen. The membran es were stored at -70 C. Protein concentration was determined spectroscopically by Bradford protein assay.

For th e binding assay, [ 33 P]sphingosine 1-phosphate (obtained from American Radiolabeled Chemicals, Inc) was added to membranes in 200 μl in 96-well plates

with assay concentrations of 2.5 pM [ 33 P]sphingosin e 1-phosphate, 4 mg/mJ BSA, 50 mM HEPES, pH 7.5, 100 mM NaCl, 5 mM MgC12, and 5 μg of protein. Binding was performed for 60 minutes at room temperature with gentle mixing and terminated by collecting the membranes onto GFfB filter plates. After drying the filter plates for 10 minutes, 50 μ! of Microscint40 was added to each well, and filter-bound radionuclide was measured on a Packard Top Count. Nonspecific binding was defined as the amount of radioactivity remaining in the presence of excess of unlabeled SlP. The results for the foregoing binding assays are presented in Table 1 provided below.
