UROTENSIN II RECEPTOR ANTAGONISTS

CROSS REFERENCE TO RELATED APPLICATIONS

This present application claims benefit of U.S. Provisional Patent Application Serial No. 60/757,692, filed January 10, 2006, which is incorporated herein by reference in its entirety and for all purposes.

FIELD OF THE INVENTION

The present invention relates to certain novel compounds, methods for preparing compounds, compositions, intermediates and derivatives thereof and methods for treating Urotensin-ll mediated disorders. More particularly, the compounds of the present invention are Urotensin-ll receptor antagonists useful for treating Urotensin-ll mediated disorders.

BACKGROUND OF THE INVENTION

Urotensin-ll (U-Il) is a cysteine-linked cyclic peptide, which exerts potent effects on the cardiovascular, renal, pancreatic, and central nervous systems. Originally, this substance was isolated from the urophysis (a caudal neurosecretory organ) of the goby fish (Gillichthys mirabilis) as a 12-mer, AGTAD- cyclo(CFWKYC)-V (D. Pearson. J. E. Shively, B. R. Clark, I. I. Geschwind, M. Barkley, R. S. Nishioka, H. A. Bern, Proc. Natl. Acad. ScL USA 1980, 77, 5021- 5024), but it has now been identified in all classes of vertebrates. The composition of U-Il ranges from 11 amino acids in humans to 14 amino acids in mice, always with a conserved cysteine-linked macrocycle, CFWKYC. Recently, the U-Il receptor was identified (R. S. Ames, H. M. Sarau, J. K. Chambers, R. N. Willette, N. V. Aiyar, A. M. Romanic, C. S. Louden, J. J. Foley, C. F. Sauermelch, R. W. Coatney, Z. Ao, J. Disa, S. D. Holmes, J. M. Stadel, J. D. Martin, W.-S. Liu, G. I. Glover, S. Wilson, D. E. McNulty, C. E. Ellis, N. A. Elshourbagy, U. Shabon, J. J. Trill, D. W. P. Hay, E. H. Ohlstein, D. J. Bergsma, S. A. Douglas, Nature (London) 1999, 401, 282-286) as a G-protein-coupled receptor (GPCR) previously known as the GPR14 orphan receptor, (M. TaI, D. A. Ammar, M. Karpuj, V. Krizhanovsky, M. Nairn, D. A. Thompson, Biochem. Biophys. Res. Commun. 1995, 209, 752-759; and A. Marchese, M. Heiber, T. Nguyen, H. H. Q. Heng, V. R. Saldivia, R. Cheng, P. M. Murphy, L.-C. Tsui, X. Shi, P. Gregor, S. R. George, B. F. O'Dowd, J. M. Docherty, Genomics 1995, 29, 335-344) which is expressed predominantly in cardiovascular tissues.

Goby U-Il possesses powerful vasoconstrictor activity in fish, mammals, and humans (J. M. Conlon, K. Yano, D. Waugh, N. Hazon, J. Exp. Zoo!. 1996, 275, 226-238; F. Bόhm, J. Pernow, Br. J. Pharmacol. 2002, 135, 25-27).

Moreover, it appears to be the most potent vasoconstrictor known, (S. A. Douglas, E. H. Ohlstein, Trends Cardiovasc. Med. 2000, 10, 229-237), causing concentration-dependent contraction of isolated arterial rings of rats and humans with an EC5O value of less than 1 nM, which is ca. ten times more potent than endothelin-1. Recently, Kikkawa, H. and Kushida, H. in International Publication WO 2005/072226 disclosed the use of Urotensin-ll antagonists for the prevention and/or treatment of inflammatory bowel diseases including, but not limited to, Crohn's disease, ulcerative colitis, and inflammatory colitis caused by bacteria, ischemia, radiation, drugs, or chemical substances. Relative to the role of U-Il in chronic vascular disease, this peptide was reported to induce hypertrophy in cardiomyocytes (Y. Zou, R. Nagai, T. Yamazaki, FEBS Letters 2001 , 508, 57-60) and the proliferation of smooth muscle cells (T. Watanabe, R. Pakala, T. Katagiri, C. R. Benedict, Circulation 2001 , 104, 16-18), which suggests an involvement in heart failure and atherosclerosis. In addition, U-Il has been shown to increase peripheral vascular tone, a characteristic of chronic heart failure (M. Lim, S. Honisett, C. D. Sparkes, P. Komesaroff, A. Kompa, H. Krum, Circulation 2004, 109, 1212-1214). Recent results have shown increased U-Il receptor levels observed in the atherosclerotic lesions of the human aorta (N. Bousette, L. Patel, S. A. Douglas, E. H. Ohlstein, A. Giaid, Atherosclerosis 2004, 176, 117-123). Relative to healthy individuals, the expression of U-ll-like immunoreactivity was 2-fold higher in the plasma of patients with renal dysfunction who were not on dialysis, and 3-fold higher in those on haemodialysis (K. Totsune, K. Takahashi, Z. Arihara, M. Sone, F. Satoh, S. Ito, Y. Kimura, H. Sasano, O. Murakami, Lancet 2001, 358, 810-811). Recently, Kinoshita, M. and Kushida, H. in International Publication WO 2005/034873 disclosed the use of Urotensin-ll antagonists for reducing nephrotoxicity and diarrhea caused by anti-neoplastic agents.

U-Il has been described as a potential mediator in diabetes. For instance, U-Il was shown to inhibit the release of insulin in the perfused rat pancreas in response to increasing glucose levels (R. A. Silvestre, J. Rodriguez-Gallardo, E. M. Egido, J. Marco, Horm. Metab. Res.2001, 33, 379-381). Elevated U-Il levels were seen in patients with diabetis mellitus (K. Totsune, K. Takahashi, Z. Arihara, M. Sone, S. Ito, O. Murakami, Clin. ScL 2003, 104, 1-5) even without renal failure.

A U-Il antagonist may be useful for the treatment of pain, neurological and psychiatric conditions, migraine, neuromuscular deficit, and cardiovascular disorders. ICV (intracerebroventricular) administration of U-Il increases rearing, grooming, and motor activity suggesting a CNS stimulatory activity (J. Gartlon, F. Parker, D. C. Harrison, S. A. Douglas, T. E. Ashmeade, G. J. Riley, Z. A. Hughes, S. G. Taylor, R. P. Munton, J. J. Hagan, J. A. Hunter, D. N. C. Jones, Psychopharmacology 2001 , 155, 426-433). U-Il increases Fos expression in the cingulate cortex and periaqueductal grey brain regions important in cognitive, emotional, and motor responses; the perceptions of pain; and panic responses (J. E. Gartlon, T. Ashmeade, M. Duxon, J. J. Hagan, D. N. C. Jones, Eur. J. of Pharmacol. 2004, 493, 95-98). U-Il induces anxiogenic-like responses in rodents in the elevated plus maze and hole-board tests (Y. Matsumoto, M. Abe, T. Watanabe, Y. Adachi, T. Yano, H. Takahashi, T. Sugo, M. Mori, C. Kitada, T. Kurokawa, M. Fujino, Neuroscience Letters 2004, 358, 99-102).

The present invention includes within its scope prodrugs of the compounds of this invention. In general, such prodrugs will be functional derivatives of the compounds that are readily convertible in vivo into the required compound. Thus, in the methods of treatment of the present invention, the term "administering" shall encompass the treatment of the various disorders described with the compound specifically disclosed or with a compound which may not be specifically disclosed, but which converts to the specified compound in vivo after administration to the patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in "Design of Prodrugs", ed. H. Bundgaard, Elsevier, 1985. Compound Forms

The term "form" means, in reference to compounds of the present invention, such may exist as, without limitation, a salt, stereoisomer, tautomer, crystalline, polymorph, amorphous, solvate, hydrate, ester, prodrug or metabolite form. The present invention encompasses all such compound forms and mixtures thereof. The term "isolated form" means, in reference to compounds of the present invention, such may exist in an essentially pure state such as, without limitation, an enantiomer, a racemic mixture, a geometric isomer (such as a cis or trans stereoisomer), a mixture of geometric isomers, and the like. The present invention encompasses all such compound forms and mixtures thereof. Certain compounds of Formula (I) may exist in various stereoisomeric or tautomeric forms and mixtures thereof. The invention encompasses all such compounds, including active compounds in the form of essentially pure enantiomers, racemic mixtures and tautomers.

The compounds of the present invention may be present in the form of pharmaceutically acceptable salts. For use in medicines, the "pharmaceutically acceptable salts" of the compounds of this invention refer to non-toxic acidic/anionic or basic/cationic salt forms.

Suitable pharmaceutically acceptable salts of the compounds of this invention include acid addition salts which may, for example, be formed by mixing a solution of the compound according to the invention with a solution of a pharmaceutically acceptable acid such as hydrochloric acid, sulphuric acid, fumaric acid, maleic acid, succinic acid, acetic acid, benzoic acid, citric acid, tartaric acid, carbonic acid or phosphoric acid.

Furthermore when the compounds of the present invention carry an acidic moiety, suitable pharmaceutically acceptable salts thereof may include alkali metal salts, e.g. sodium or potassium salts; alkaline earth metal salts, e.g. calcium or magnesium salts; and salts formed with suitable organic ligands, e.g. quaternary ammonium salts. Thus, representative pharmaceutically acceptable salts include the following: acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, calcium, camsylate (or camphosulphonate), carbonate, chloride, clavulanate, citrate, dihydrochloride, edetate, fumarate, gluconate, glutamate, hydrabamine, hydrobromine, hydrochloride, iodide, isothionate, lactate, malate, maleate, mandelate, mesylate, nitrate, oleate, pamoate, palmitate, phosphate/diphosphate, salicylate, stearate, sulfate, succinate, tartrate, tosylate. The invention includes compounds of various isomers and mixtures thereof. The term "isomer" refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. Such substances have the same number and kind of atoms but differ in structure. The structural difference may be in constitution (geometric isomers) or in an ability to rotate the plane of polarized light (stereoisomers).

The term "optical isomer" means isomers of identical constitution that differ only in the spatial arrangement of their groups. Optical isomers rotate the plane of polarized light in different directions. The term "optical activity" means the degree to which an optical isomer rotates the plane of polarized light.

The term "racemate" or "racemic mixture" means an equϊmolar mixture of two enantiomeric species, wherein each of the isolated species rotates the plane of polarized light in the opposite direction such that the mixture is devoid of optical activity. The term "enantiomer" means an isomer having a nonsuperimposable mirror image. The term "diastereomer" means stereoisomers that are not enantiomers.

The term "chiral" means a molecule which, in a given configuration, cannot be superimposed on its mirror image. This is in contrast to achiral molecules which can be superimposed on their mirror images.

The invention is considered to include the tautomeric forms of all compounds of Formula I. In addition, for chiral embodiments of the invention, the invention is considered to include pure enantiomers, racemic mixtures, as well as mixtures of enantiomers having 0.001% to 99.99% enantiomeric excess. In addition, some of the compounds represented by Formula I may be prodrugs, i.e., derivatives of a drug that possess superior delivery capabilities and therapeutic value as compared to the active drug. Prodrugs are transformed into active drugs by in vivo enzymatic or chemical processes.

The two distinct mirror image versions of the chiral molecule are also known as levo (left-handed), abbreviated L, or dextro (right handed), abbreviated D, depending on which way they rotate polarized light. The symbols "R" and "S" represent the configuration of groups around a stereogenic carbon atom(s).

An example of an enantiomerically enriched form isolated from a racemic 5 mixture includes a dextrorotatory enantiomer, wherein the mixture is substantially free of the levorotatory isomer. In this context, substantially free means the levorotatory isomer may, in a range, comprise less than 25% of the mixture, less than 10 %, less than 5 %, less than 2 % or less than 1 % of the mixture according to the formula:

I D o/ T (mass levorotatory}

■ υ % levorotatory = — x 100

(mass dextrorotatory) + (mass levorotatory)

Similarly, an example of an enantiomerically enriched form isolated from a racemic mixture includes a levorotatory enantiomer, wherein the mixture is substantially free of the dextrorotatory isomer. In this context, substantially free means the dextrorotatory isomer may, in a range, comprise less than 25% of the 15 mixture, less than 10 %, less than 5 %, less than 2 % or less than 1 % of the mixture according to the formula:

(mass dextrorotatory)

% dextrorotatory = * — x 100

(mass dextrorotatory) + (mass levorotatory)

"Geometric isomer" means isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl 20 ring, or to a bridged bicyclic system. Substituent atoms (other than hydrogen) on each side of a carbon-carbon double bond may be in an E or Z configuration. In the "E" configuration, the substituents are on opposite sides in relationship to the carbon- carbon double bond. In the "Z" configuration, the substituents are oriented on the same side in relationship to the carbon-carbon double bond.

25 Substituent atoms (other than hydrogen) attached to a ring system may be in a cis or trans configuration. In the "cis" configuration, the substituents are on the same side in relationship to the plane of the ring; in the "trans" configuration, the substituents are on opposite sides in relationship to the plane of the ring. Compounds having a mixture of "cis" and "trans" species are designated "cis/trans".

The isomeric descriptors ("R," "S," "E," and "Z") indicate atom configurations relative to a core molecule and are intended to be used as defined in the literature.

Where the processes for the preparation of the compounds according to the invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form, or individual enantiomers may be prepared either by enantiospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation of diastereomeric pairs by salt formation with an optically active acid, such as (-)-di-p-toluoyl-d-tartaric acid and/or (+)-di-p-toluoyl-l-tartaric acid followed by fractional crystallization and regeneration of the free base. The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column.

Furthermore, compounds of the present invention may have at least one crystalline, polymorph or amorphous form. The plurality of such forms are included in the scope of the invention. In addition, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents (e.g., organic esters such as ethanolate and the like). The plurality of such solvates are also intended to be encompassed within the scope of this invention.

During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J.F.W. McOmie, Plenum Press, 1973; and T.W. Greene & P.G.M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known from the art.

Even though the compounds of the present invention (including their pharmaceutically, acceptable salts and pharmaceutically acceptable solvates) can be administered alone, they will generally be administered in admixture with a pharmaceutical carrier, excipient or diluent selected with regard to the intended route of administration and standard pharmaceutical or veterinary practice. Thus, the present invention is directed to pharmaceutical and veterinary compositions comprising compounds of Formula (I) and one or more pharmaceutically acceptable carriers, excipients or diluents.

By way of example, in the pharmaceutical and veterinary compositions of the present invention, the compounds of the present invention may be admixed with any suitable binder(s), lubricant(s), suspending agent(s), coating agent(s), and/or solubilising agent(s). Tablets or capsules of the compounds may be administered singly or two or more at a time, as appropriate. It is also possible to administer the compounds in sustained release formulations.

Alternatively, the compounds of the general Formula (I) can be administered by inhalation or in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or dusting powder. An alternative means of transdermal administration is by use of a skin patch. For example, they can be incorporated into a cream consisting of an aqueous emulsion of polyethylene glycols or liquid paraffin. They can also be incorporated, at a concentration of between 1 and 10% by weight, into an ointment consisting of a white wax or white soft paraffin base together with such stabilizers and preservatives as may be required.

For some applications, preferably the compositions are administered orally in the form of tablets containing excipients such as starch or lactose, or in capsules or ovules either alone or in admixture with excipients, or in the form of elixirs, solutions or suspensions containing flavoring or coloring agents.

The compositions (as well as the compounds alone) can also be injected parenterally, for example intracavemosally, intravenously, intramuscularly or subcutaneously. In this case, the compositions will comprise a suitable carrier or diluent.

For parenteral administration, the compositions are best used in the form of a sterile aqueous solution which may contain other substances, for example enough salts or monosaccharides to make the solution isotonic with blood.

For buccal or sublingual administration the compositions may be administered in the form of tablets or lozenges which can be formulated in a conventional manner.

By way of further example, pharmaceutical and veterinary compositions containing one or more of the compounds of the invention described herein as the active ingredient can be prepared by intimately mixing the compound or compounds with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending upon the desired route of administration (e.g., oral, parenteral). Thus for liquid oral preparations such as suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, stabilizers, coloring agents and the like; for solid oral preparations, such as powders, capsules and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Solid oral preparations may also be coated with substances such as sugars or be enteric-coated so as to modulate the major site of absorption. For parenteral administration, the carrier will usually consist of sterile water and other ingredients may be added to increase solubility or preservation. Injectable suspensions or solutions may also be prepared utilizing aqueous carriers along with appropriate additives.

Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal skin patches well known to those skilled in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

It is also apparent to one skilled in the art that the therapeutically effective dose for active compounds of the invention or a pharmaceutical composition thereof will vary according to the desired effect. Therefore, optimal dosages to be administered may be readily determined and will vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease condition. In addition, factors associated with the particular subject being treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to an appropriate therapeutic level. The above dosages are thus exemplary of the average case. There can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention.

Compounds of this invention may be administered in any of the foregoing compositions and dosage regimens or by means of those compositions and dosage regimens established in the art whenever use of the compounds of the invention as analgesics is required for a subject in need thereof.

The invention also provides a pharmaceutical or veterinary pack or kit comprising one or more containers filled with one or more of the ingredients of the pharmaceutical and veterinary compositions of the invention. Optionally associated with such container(s) can be a notice in the form prescribed by a governmental agency regulating the manufacture, use or safe of pharmaceuticals or biological products, which notice reflects approval by the agency of manufacture, use or sale for human administration. The present invention includes the use of an instant compound in the manufacture of a medicament for treating a Urotensin fl-mediated disorder.

The present invention is also directed to a method for treating a Urotensin-ll mediated disorder. An embodiment of the present invention is a method for treating a disorder including, but not limited to, vascular hypertension, heart failure, atherosclerosis, renal failure, nephrotoxicity and diarrhea caused by antineoplastic agents, post-myocardial infarction, pulmonary hypertension/fibrosis, diabetes, and CNS indications including pain, Alzheimer's, convulsions, depression, migraine, psychosis, anxiety, neuromuscular deficit, and stroke. The present method of using Urotensin Il receptor antagonists to reduce anti-neoplastic agent induced diarrhea and nephrotoxicity is applicable in any situations when anti-neoplastic agents (such as cisplatin, cis- diaminedichloroplatinum) are being administered to treat cancers or tumors. However, most often UII antagonists are used when tumors or cancers being treated are those of solid malignancies, notably those of the bladder, cervix, lung, ovary, and testis such as testicular tumor; bladder cancer; ureterpyelonephritic tumor; prostatic cancer; ovarian cancer; head and neck cancer; non-small-cell lung cancer; esophageal cancer; cervical cancer; neuroblastoma; gastric cancer; small cell lung cancer; bone cancer; non-Hodgkin's lymphomas; tumors of brain, endometrium, upper gastrointestinal tract, head and neck, and thymus; neuroblastoma; and sarcoma of bone and soft tissue.

Recent data (American Heart Association Scientific Sessions 2005, "SB- 611812 in the treatment of heart failure", by Nicolas Bousette at Montreal General Hospital, Canada) has demonstrated that Urotensin Il receptor antagonists may be useful for improving cardiac function and for cardiac remodeling associated with chronic heart failure (CHF).

A therapeutically effective amount for use of the instant compounds or a pharmaceutical composition thereof comprises a dose range from about 0.1 mg to about 3000 mg, from about 0.1 mg to about 1000 mg, from about 10 mg to about 500 mg or from about 1 mg to about 100 mg of active ingredient in a regimen of about 1 to 4 times per day for an average (70 kg) human; although, it is apparent to one skilled in the art that the therapeutically effective amount for active compounds of the invention will vary as will the conditions being treated. Optimal dosages of the compounds of Formula (I) to be administered for the treatment of or prevention of Urotensin Il mediated disorders may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease condition. In addition, factors associated with the particular patient .being treated, including patient age, weight, diet and time of administration, will result in the need to adjust dosages.

For oral administration, a pharmaceutical composition is preferably provided in the form of tablets containing 0.01 , 10.0, 50.0, 100, 150, 200, 250, and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the subject to be treated.

Example 41 of the present invention is directed to compounds of Formula (I) or a form thereof as described herein selected from the group consisting of:

BIOLOGICAL EXAMPLES

Example 1 Rat UIf Calcium Mobilization FLIPR Assay A calcium mobilization assay based on a Fluorescence Imaging Plate

Reader (FLIPR, Molecular Devices, Sunnyvale, CA) was used to determine antagonist activity, after a 5 min incubation, in response to the agonist cyclic peptide (Ac)-CFWK(2-Nal)C-NH2 (FLIPR EC50 = 0.54 ± 0.2 nM, rU-ll Ki = 0.12 ± 0.05 nM) at 1 nM (W. A. Kinney, H. R. Almond, Jr., J. Qi, C. E. Smith, R. J. Santulli, L. de Garavilla, P. Andrade-Gordon, D. S. Cho, A. M. Everson, M. A. Feinstein, P. A. Leung, B. E. Maryanoff, Angew. Chem., Intl. Ed. 2002, 41 , 2940- 2944), in CHO cells transfected with rat GPR14 (U-Il receptor) (M. TaI, D. A. Ammar, M. Karpuj, V. Krizhanovsky, M. Nairn, D. A. Thompson, Biochem.

Biophys. Res. Commun. 1995, 209, 752-759. A. Marchese, M. Heiber, T. Nguyen, H. H. Heng, V. R. Saldivia, R. Cheng, P. M. Murphy, L. C. Tsui, X. Shi, P. Gregor, Genomics 1995, 29, 335-344.).

To derive these cells, the complete coding sequence of rat U-H (Genbank Accession No. U32673) was amplified by nested PCR from rat heart marathon- Ready cDNA. PCR was carried out by using the DNA polymerase PFU (Stratagene) following conditions suggested by the manufacturer. The PCR products were cloned into pcDNA3 (Invitrogen) digested with EcoR I and Xba I. Clones containing rat U-Il receptor were verified by complete sequencing of the U-Il receptor insert to ensure a lack of PCR-introduced errors. The constructed vector was transfected into CHO cells by using lipofectamine (GIBCO BRL). CHO cells with high expression of rat U-Il receptor were selected and established as stable cell lines by using G418. CHO cells were seeded at 25,000 cells per well into 96-well, black-wall, clear-bottom microtiter plates 24 h before assay. Cells in culture media (DMEM/F12 containing 15 mM HEPES, L-glutamine, pyridoxine hydrochloride; 10% fetal bovine serum; 1 mg/mL G418 sulfate; antibiotic- antimycotic; pH 7.4) were loaded with proprietary dye, from the FLIPR Calcium Assay Kit (Molecular Devices), prepared in assay buffer (Hanks Balanced Salts Solution, 20 mM HEPES, 0.1% BSA, 2.5 mM probenecid, pH 7.4), and incubated for 1 h at 37 0C. Calcium mobilization determinations were performed at room temperature (23 0C). The use of rat GPR14 was considered acceptable, because human U-Il has similar affinity for human or rat GPR14 in the transfected cells (S. A. Douglas, E. H. Ohlstein, Trends Cardiovasc. Med. 2000, 10, 229-237).

Results for Calcium Mobilization using the Rat UII FLlPR Assay are shown in Table 1 and Table 2. Table 2 contains IC50 values which represent an average value for the compound tested.

Example 2 Human Radioligand Binding Assay

Human Skeletal Muscle Myoblasts (HSMM) were obtained from Cambrex, and were cultured according to manufacturer's instruction. Cell viability was examined by trypan blue exclusion. Cells at less than 4 passages were used in all studies. For the (125I)-U-II binding experiments (Described in: "Characterization of Functional Urotensin Il Receptors in Human Skeletal Muscle Myoblasts: Comparison with Angiotensin Il Receptors" J. Qi, L. K. Minor, C. Smith, B, Hu, J. Yang, P. Adrade-Gordon, B. Damiano, Peptides 2005, 26, 683-690.), HSMM were plated in 12-well Costar plates in complete medium for 48 h to reach 70% confluence. The binding medium used was Dulbecco's modified Eagle's medium (DMEM) containing 2 mg/ml BSA and 25 mM HEPES (pH 7.4). The cells were washed at room temperature 2x with the binding medium, and were incubated with 0.2 ml per well of prepared binding medium containing 0.150 nM (125I)-U-II and compounds for 3 h. The cells were washed 4x with the binding medium and solubilized in 1% SDS and 0.5 N NaOH. Radioactivity was quantified by gamma counting.

Radiolabeled (125I)-U-II bound specifically and saturably to intact adherent HSMM (Figure 1A). The binding assays were performed at 25 °C to lower nonspecific uptake of (125I)-U-II by the cells that was seen at 37 "C. Using this method, the nonspecific binding was below 10% of total binding. Analysis of the saturation data using the non-linear curve-fitting technique of GraphPad Prism Version 3.0 revealed that the best fit observed was for a one-site model. The derived Kd value was 0.309 ± 0.022 nM (N=3 experiments) with the Hill slope close to unity. Based on the number of cells in a well and Bmax value, the number of UT receptors in HSMM was 2311 ± 236 per cell (N=3 experiments). A time course experiment demonstrated that (125I)-U-II binding to HSMM reached steady state at 3 h, and remained constant up to 5 hr, the longest time point measured. Human U-Il, when add at time 0, efficiently displaced specific binding of (125I)-U-II with a Ki of 0.425 ± 0.096 nM (N=3 experiments). The resulting data is shown in Table 3 and Table 4. Table 4 contains IC50 values which represent an average value for the compound tested.

Example 3 Human UII Calcium Mobilization Assay

6D9 human rhabdomyosarcoma cells were seeded into tissue culture treated 384-well black-walled clear bottom plates (3712, Coming Incorporated, Corning, NY) at 8,000 cells/well in 25 μL of culture medium, and maintained in an incubator (5% CO2 at 37 0C) for 22 hrs prior to the calcium mobilization assay. 25 μL of dye solution was added to the wells such that the final liquid volume before agonist/antagonist treatment was 50 μL for all assays. The cell plates were incubated at 37 0C for 45 minutes and the fluorescence intensity was measured on a Fluorometric Imaging Plate Reader (FLIPRTETRA, Molecular Devices, Sunnyvale, CA).

Antagonist and agonist U-Il were added at room temperature on the FLIPRTETRA, and the fluorescence intensity before and after addition was measured over a period of 4 minutes. The dye incubation time and temperature as well as instrument setting was adjusted so the fluorescence intensity could be compared between plates on the same day. EC50 and IC50 were analyzed using GraphPad Prism 4 software (GraphPad Software Inc., San Diego, CA).

Materials and reagent Preparation: Human Rhabdomyosarcoma cells (6D9: isolated by dilution subcloπing of RMS13 cells, ATCC® Number. CRL-2061 , American Type Culture Collection ATCC, Manassas, VA) was maintained in RPMI-1640 medium (30-2001 , ATCC, Manassas, VA) supplemented with 10% (v/v) Fetal Bovine Serum (SH30071.03, Hyclone, Logan, UT).

Dye preparation: BD™ Calcium Assay Kit (80500-301 , BD Biosciences, Rockville, MD) was prepared according to the manufacture's instruction in 1X Hanks' balanced salt solution (HBSS1 21-023-CV, Mediatech, Inc. Herndon, VA) containing 20 mM HEPES buffer (25-060-CI, Mediatech, Inc. Herndon, VA). Final dye loading conditions included 1.25 mM probenecid (P36400, Invitrogen, Carlsbad, CA) and 0.01 % FBS.

Agonist and antagonist preparation: Human U-Il stock (U-7257, Sigma, St. Louis, MO) was prepared in acidified. water (pH 4.95) at 5 mM. Urantide (PUT-

3639-PI, Peptide International, Louisville, KY) was prepared in water at 5 mM. For assays, U-Il agonist, U-Il antagonist and urantide were diluted with HBSS/HEPES containing 0.01 % FBS.

Test compounds were dissolved in DMSO at 10 mM concentration. The serial dilutions were carried out in HBSS/HEPES. The highest final DMSO concentration was at 0.1%.
