These molecules may serve as energy sources; they may provide essential chemical elements, such as calcium, nitrogen or iron; or they may be complete molecules, e.g., certain amino acids, fatty acids and vitamins, that the cells need but cannot synthesize themselves. Digestion which incorporates the. processes of breakdown and assimilation of food materials as well as the elimination of undigestable waste material takes place in a long convoluted tube that extends from the mouth to the anus, known as the gastrointestinal (Gl) tract. The Gl tract begins with the oral cavity, the mouth, and continues to include the, pharynx, esophagus, stomach, small intestine, large intestine and anus. The Gl tract, from beginning to end, has four tissue layers: (1) the mucosa, which is the innermost layer, is made up of columnar epithelial cells that are in direct contact with ingested materials and facilitate fluid and electrolyte transport and digestion and absorption of nutrients, an underlying basement membrane consisting of connective tissue and a thin layer of smooth muscle; (2) the submucosa, which is the second innermost layer, is made up of connective tissue containing small clusters of nerve cells and nerve fibers, and blood and lymph vessels; (3) the muscularis externa, which is the third

innermost layer, is made up of two separate layers of smooth muscle tissue oriented in opposing directions and containing a vast network of nerve cell clusters and nerve fibers sandwiched in-between these layers; and (4) the serosa, which is the outermost layer consisting of a coating of connective tissue that is in contact with the environment of the peritoneal cavity of the abdomen.

Along most of the Gl tract, the muscularis externa is made up of two opposing layers of smooth muscle, the inner layer, in which the cellular orientation is perpendicular to the long axis of the gut, and the outer layer, in which cellular orientation is parallel to the long axis of the gut. Coordinated contractions of these muscle layers produce ring-like constrictions that mix food, as well as wave-like motions, known as peristalsis, that move food along the Gl tract. At several points, the circular layer of muscle thickens into heavy bands forming valve-like constrictions called sphincters, which by relaxing and contracting, act to regulate the passage of food from one area of the Gl tract to another.

Breakdown and assimilation of nutrients from food materials is accomplished chiefly by the highly coordinated activities of the stomach and small intestine. The stomach is influenced by both the nervous and endocrine systems. Anticipation of food and the presence of food in the mouth stimulate churning movements of the stomach and the production of gastric juices. When food reaches the stomach, its presence causes the release of the hormone gastrin from gastric endocrine cells into the bloodstream. Gastrin acts on the cells of the stomach to increase their secretion of gastric juices. Food is converted in the stomach to a semiliquid mass as a result of gastric juices, including pepsin, hydrochloric acid and the churning motions. The food is then emptied into the small " intestine, where the breakdown of food is completed. The resulting nutrient molecules are then absorbed into the circulatory system, from which they are delivered to the individual cells. The small intestine contains a variety of digestive secretions, some produced by the intestinal cells and some by the pancreas and liver. Other epithelial cells, the goblet cells of the mucosa, secrete mucus. The digestive activities of the small

intestine are coordinated and regulated by hormones. In addition to hormonal influences, the intestinal tract is also regulated by the autonomic and enteric nervous systems, which are involved in regulating the secretion of digestive enzymes, and coordinating the activities of contraction and epithelial secretion. Thus, a complex interplay of stimuli and checks and balances serves to activate digestive enzymes, adjust the chemical environment and regulate the movement of ingested materials in the intestines.

The large intestine is involved in the absorption of water, sodium and other electrolytes. Some of its epithelial cells secrete mucus, which lubricates undigested food residue. Large amounts of water enter the stomach and small intestine by osmosis from body fluids or as secretions of the glands lining the digestive tract. When the absorption process is interfered with and/or secretions from the mucosal glands becomes enhanced, as in diarrhea, severe dehydration can result. Functional bowel disorders involve abnormal motility and secretion within organs of the Gl tract, and are characterized by abdominal discomfort/pain. The Criteria for these disorders are summarized by gastroenterologists in the 'Rome Il criteria' (See, for example, Rome Il Diagnostic criteria for the Functional Gastrointestinal Disorders, Second Edition, Senior Editor Douglas A. Drossman, M.D., Management Services, McLean, VA (2000)). Based on these criteria the disorders are common and include, but are not limited to, functional dyspepsia, irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), non-erosive reflux disease (NERD), and chronic constipation (including colonic inertia, idiopathic pseudoobstruction). GERD is extremely prevalent, is usually associated with non-cardiac chest pain and may be treated with acid-suppressing agents and prokinetic agents. IBS is characterized by the presence of reoccurring constipation and/or diarrhea, which can be associated with gaseous distention/bloating and abdominal discomfort/pain (Thompson, W.G. and Heaton, K.W. Gastroenterology\9BQ, 79, 283-288). The onset of the pain of IBS is associated with a change in the frequency and/or form of stool and-can be relieved by defecation. IBS is an extremely prevalent condition that occurs

to varying severity in 10-15% of the population (Saϊto, Y.A.; Schoenfeld, P.; and Locke, G.R. Am. J. Gastroenterol. 2002, 97, 1910-1915). The pain may be treated with smooth muscle relaxants and antidepressants (Jackson, J. L.; O'Malley, P.G.; Tomkins, G.; Balden, E.; Santoro, J.; and Kroenke, K.; Am. J. Med. 2000, 108, 65-72; Jailwala, J.; Imperiale, T.F.; and Kroenke, K.; Ann. Intern. Med. 2000, 733:136-147; Akehurst, R. and Kaltenthaler, E. Gut 2001, 48, 272-282; Poynard, T.; Regimbeau, C; and Benhamou, Y.; Aliment Pharmacol. Ther. 2001, 15, 355-361). Severe diarrhea predominant IBS is treated by alosetron, whereas constipation predominant IBS is treated by tegaserod. Functional dyspepsia is a disorder of the upper Gl tract with symptoms exacerbated by a meal and associated with early satiety, nausea and vomiting. Although its etiology is unknown, prokinetic agents may relieve the symptoms of IBS. In some patients there is overlap in symptoms between GERD/NERD, functional dyspepsia and IBS. Treatments for functional bowel disorders, such as IBS, have low efficacy and are associated with adverse effects. For example, alosetron is approved by the FDA on a risk management program because it is associated with an increase in ischemic colitis. No treatments effectively alleviate pain in functional bowel disorders.

In addition to functional disorders, inflammatory bowel diseases (IBD) are common and include ulcerative colitis (UC) and Crohn's disease (CD).

Although there may be a genetic component to CD, the etiology of both UC and CD is unknown. UC is a diffuse mucosal disease of the colon, characterized by inflammation and ulceration, which is associated with diarrhea and abdominal cramping. The mucosal inflammation progresses from the rectal area to eventually extend through the large bowel. CD is a transmural inflammation that most frequently involves the distal small bowel and colon. The inflammation can result in ulcers of varying involvement and in severe cases can result in transmural scarring and chronic inflammation. Both infectious and dysregulated immune functions may contribute to disease onset. Therapies for IBD include corticosteroids, immunosuppressives (azathioprine, mercaptopurine, and methotrexate) and aminosalicylates (5-ASA). These therapies involve suppression of the immune system by mimicking

corticosteroids, or have unknown mechanisms of action. Oral corticosteroid use is associated with serious adverse effects, whereas immunosuppressives and aminosalicylates are only moderately effective. Infliximab (a chimeric monoclonal anti-tumor necrosis factor antibody) is effective in CD, however, its use is associated with the presence of antibodies, which reduce its efficacy. There are currently no treatments that target the motility and secretory abnormalities or painful sensation that are associated with gut inflammation.

The cysteine rich proteins known as Prokineticin 1 (PK1) and Prokineticin 2 (PK2), as well as variants, fragments and molecules having PK activity, have been identified. PK1 and PK2 have been shown to contract gastrointestinal smooth muscle (Li, M.; Bullock, CM.; Knauer, D.J.; Ehlert, FJ. ; and Zhou, Q.Y., MoI. Pharmacol. 2001, 59, 692-698), and suppress feeding (Negri, L; Lattanzi, R.; Giannini, E.; De Felice, M.; Colucci, A. and Melchiorri, P. Brit. J. Pharmacol. 2004, 142, 181-191). PK1 and PK2 act on both PK1 and PK2 receptors, and limited structural changes of C-terminal cysteine-rich regions of these related PKs are tolerated. For example, chimeric PKs, where the cysteine-rich domains of PK1 and PK2 were exchanged between the two and a splice variant of PK2 that included a 21 residue insertion in its C-terminal domain retained activity (Bullock, CM; Li J.D.; Zhou, Q.Y.; MoI. Pharmacol. 2004, 65(3), 582-8). A PK variant binds to receptors of primary sensory neurons, and results in an intense sensitization of peripheral nociceptors to thermal and mechanical stimuli (Mollay, C; Weschelberger, C; Mignogna, G.; Negri, L.; Melchiorri, P.; Barra, D.; Kreil, G.; Eur. J. Pharmacol. 1999, 374, 189- 196; Negri, L.; Lattanzi, R.; Giannini, E.; Metere, A.; Colucci, M.; Barra, D.; Kreil, G.; Melchiorri, P.; Brit. J. Pharmacol. 2002, 137(8), 1147-54).

PK1 (also known as EG-VEGF) induces proliferation, migration and fenestration in capillary endothelial cells derived from endocrine glands. The expression of PK mRNA has been observed in steroidogenic glands, ovary, testis, adrenal and placenta. (LeCouter, J.; Kowalski, J.; Foster, J.; Hass, P., Zhang, Z.; Dillard-Telm, L, Frantz, G., Rangell, L.; DeGuzman, L.; Keller, G.A.; Peale, F.; Gurney, A.; Hillan, K.J.; Ferrara, N. Nature 2001, 412.(6850), 877-84). In 2002 the identification of the PK1 receptor provided a novel molecular basis for

the regulation of angiogenesis in endocrine glands (Masuda, Y.; Takatsu, Y.; Terao, Y.; Kumano, S.; Ishibashi, Y.; Suenaga, M.; Abe, M.; Fukusumi, S.; Watanabe, T.; Shϊntani, Y.; Yamada, T.; Hinuma, S.; Inatomi, N.; Ohtaki, T.; Onda, H.; Fujino, M.; Biochem. Biophys. Res. Commun. 2002, 293(1), 396- 402;LeCouter, J.; Lin, R.; Ferrara, N.; Cold Spring Harb Symp Quant Biol. 2002, 67, 217-21 ). For example, adenoviral delivery of PK1 to the mouse testis results in a potent angiogenic response (LeCouter, J.; Lin, R.; Tejada, M.; Frantz, G.; Peale, F.; Hillan, KJ.; Ferrara, N. Proc. Natl. Acad. ScL USA. 2003, 100, 2685- 90). Recently, it was shown that PK1 mRNA is not normally expressed in colorectal normal mucosa but is detected in colorectal cancer cells (Goi, T.;

Fujioka, M.; Satoh, Y.; Tabata, S.; Koneri, K.; Nagano, H.; Hirono, Y.; Katayama, K.; Hirose, K. and Yamaguchi., Cancer Res. 2004, 64,1906-1910).

WO200236625 discloses PK1 and PK2 polynucleotides and polypeptides and uses thereof. U.S. 20040156842 and corresponding U.S. Patent No. 6,485,938 disclose the use of peptide antagonists of PK1 and PK2 to treat inflammation in the intestine. The references disclose that the antagonists include antibodies that specifically bind with PK1 and PK2 and receptors that bind to amino acid sequences disclosed therein. WO2004087054 discloses methods of modulating gastric acid or pepsinogen secretion by administering a prokineticin receptor antagonist to alter one or more indicia of gastric acid secretion. The reference discloses that the prokineticin receptor antagonist is a modified version of a prokineticin from any species that contains an amino acid sequence at least 80% identical to an amino acid sequence disclosed therein.

Prokineticin 2 receptor antagonists are useful in the treatment and prevention of various mammalian disease states, for example, visceral pain that is associated with IBS and IBD. Additionally, PK2 receptor antagonists are useful for the treatment of GERD or other forms of secretory diarrhea. And, PK2 receptor antagonists are useful in treating cancer-specific angiogenesis factor in the large intestine and reproductive organs.

It is an object of the present invention provide a method of treating or ameliorating a condition mediated by a prokineticin 2 receptor.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the following terms are intended to have the following meanings:

With reference to substituents, the term "independently" means that when more than one of such substituent is possible, such substituents may be the same or different from each other. Therefore, designated numbers of carbon atoms (e.g. Cv 8 ) shall refer independently to the number of carbon atoms in an alkyl or cycloalkyl moiety or to the alkyl portion of a larger substituent in which alkyl appears as its prefix root.

As used herein, unless otherwise noted, "alkyl" whether used alone or as part of a substituent group refers to straight and branched carbon chains having 1 to 8 carbon atoms or any number within this range.

Additional embodiments of the present invention include the use of those compounds wherein the substituents are selected from one or more of the variables defined herein (i.e. A-i, U 1 s, X, P, A 2 , W, and Q) are independently selected to be any individual substituent or any subset of substituents selected from the complete list as defined herein.

The compounds used in the present invention may also be present in the form of pharmaceutically acceptable salts. For use in medicine, the salts of the compounds of this invention refer to non-toxic "pharmaceutically acceptable salts" (Ref. International J. Pharm., 1986, 33, 201-217; J. Pharm.Sci., 1997 (Jan), 66, 1 , 1). Other salts well known to those in the art may, however, be useful in the preparation of compounds according to this invention or of their pharmaceutically acceptable salts. Representative organic or inorganic acids include, but are not limited to, hydrochloric, hydrobromic, hydroiodic, perchloric, sulfuric, nitric, phosphoric, acetic, propionic, glycolic, lactic, succinic, maleic, fumaric, malic, tartaric, citric, benzoic, mandelic, methanesulfonic, hydroxyethanesulfonic, benzenesulfonic, oxalic, pamoic, 2- naphthalenesulfonic, p-toluenesulfonic, cyclohexanesulfamic, salicylic, saccharinic or trifluoroacetic acid. Representative organic or inorganic bases

include, but are not limited to, basic or cationic salts such as benzathine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine, procaine, aluminum, calcium, lithium, magnesium, potassium, sodium and zinc.

The present invention includes within its scope methods of treatment or prevention using one or more 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.

Where the compounds used in this invention have at least one chiral center, they may accordingly exist as enantiomers. Where the compounds possess two or more chiral centers, they may additionally exist as diastereomers. It is to be understood that uses of all such isomers and mixtures thereof are encompassed within the scope of the present invention. Furthermore, some of the crystalline forms for the compounds may exist as polymorphs and as such are intended to be included for use in the present invention. In addition, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents, and such solvates are intended to be encompassed for uses within the scope of this invention.

Where the processes for the preparation of the compounds as described hereinabove 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.

During any of the processes for preparation of the compounds of Formula

(I) as described herein, 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. McOrnie, 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 Formula (I) as described herein (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 methods of treatment or prevention using one or more pharmaceutical and/or veterinary compositions comprising compounds of Formula (I) and one or more pharmaceutically or veterinarily acceptable carriers, excipients or diluents.

By way of example, in the pharmaceutical and veterinary compositions for uses according to the present invention, the compounds of Formula (I) 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 stabilisers 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 flavouring or coloring agents.

The compositions (as well as the compounds alone) can also be injected parenterally, for example intracavernosally, 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 for uses according to 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 uses according to 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.

The pharmaceutical composition for uses according to the instant invention will generally contain a per dosage unit (e.g., tablet, capsule, powder, injection, teaspoonful and the like) from about 0.001 to about 50 mg/kg. In one embodiment, the pharmaceutical composition contains a per dosage unit of from

about 0.01 to about 20 mg/kg of compound, and preferably from about 0.05 to about 10 mg/kg. Methods are known in the art for determining therapeutically effective doses for the instant pharmaceutical compositioji. The therapeutically effective amount for administering the pharmaceutical composition to a human, for example, can be determined mathematically from the results of animal studies.

A therapeutically effective amount for use of the compounds of Formula (I) or a pharmaceutical composition thereof comprises a dose range from about 0.1 mg to about 3000 mg, in particular from about 1 mg to about 1000 mg or, more particularly from about 10 mg to about 500 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.

For oral administration, a pharmaceutical composition is preferably provided in the form of tablets containing, 0.01 , 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 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.

It is also apparent to one skilled in the art that the therapeutically effective dose for active compounds of Formula (I) 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 for uses according to 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 prokineticin receptor 2 antagonists is required for a subject in need thereof.

The invention also provides methods of treatment or prevention using 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.

As antagonists of a Prokineticin 2 receptor, the compounds of Formula (I) . are useful in methods for treating or preventing a disease or condition in a mammal which disease or condition is affected by the antagonistic activity of one or more Prokineticin 2 receptors. As described above, such methods comprise administering to a mammal in need of such treatment or prevention a therapeutically effective amount of a compound of Formula (I), and enantiomers, diastereomers, tautomers, solvates, and pharmaceutically acceptable salts thereof. In particular, the compounds of Formula (I) are useful in methods for preventing or treating gastrointestinal (Gl) diseases, cancers of the Gl tract and reproductive organs, and pain. Examples of Gl diseases to be within the scope of the present invention include, but are not limited to: irritable bowel syndrome (IBS, including diarrhea-predominant, as well as alternating diarrhea/constipation forms of IBS), inflammatory bowel disease (IBD, including ulcerative colitis, and Crohn's disease), and GERD and secretory bowel disorders induced by pathogens.

Examples of cancers within the scope of the present invention include, but are not limited to, testicular cancer, ovarian cancer, Leydig cell carcinoma, and cancers of the small or large bowel. An example of pain to be covered within the scope of the present invention, is, but not restricted to, visceral hyperalgesia often associated with IBS and IBD.

While the present invention comprises methods of treatment or prevention using one or more compositions comprising one or more of the compounds of Formula (I), the present invention also comprises such uses of compositions comprising intermediates used in the manufacture of compounds of Formula <l).

A compound of formula C5 may be coupled with a compound of formula C6 in the presence of an organometallic reagent such as tetrakis(triphenylphosphine)-palladium to yield a compound of formula C7. Hydrogenation of a compound of formula C7 provides a

compound of formula Formula (1)-C1 which may be further reduced by prolonged exposure to hydrogenation conditions to yield a compound of Formula (I)-C2. Alternatively, a compound of formula C7 may be converted directly to a compound of formula (I)-C2 using conventional hydrogenation reagents and methods. One of ordinary skill in the art will recognize that the duration of exposure of a compound to hydrogenation conditions is one way of controlling the degree of reduction of an alkyne to an alkene or alkane.

HEK 293 cells were grown to 100% confluence in DMEM selective high- glucose media (Invitrogen, Carlsbad, California) containing 10% FBS, 2OmM HEPES, sodium pyruvate, penicillin and streptomycin (50 μg/ ml each), and G418 (400 mg/ L). The DMEM media used to culture the HEK 293 cells was replenished every other day with fresh media over a two-week period of time. Culture media containing the PK-1 peptide was collected, and filtered in 500 mL 0.2 μm pore size filters (Corning Incorporated, Corning, NY). The filtrate was stored in a filtrate bottle at 4 C. The PK-1 peptide containing media was purified by gravity flow passage of media over M2 agarose columns (Sigma Chemical, St. Louis, MO) at 4 C. Following media passage, the agarose columns were washed with sterile 1X PBS (pH 7.4) until protein could no longer be detected by OD 280 nm. Columns were then eluted with a 0.1 M glycine-HCI solution at pH 2.8. The eluted material was immediately neutralized, by collecting into tubes containing

1 M Tris pH8. Peak fractions were identified by OD 280 and pooled. The pooled fractions were subjected to Enterokinaεe cleavage of Flag epitope 4units/ mL overnight at room temperature. Enterokinase was removed, and sample aliquot was stored at -80 C. .

At a time of 24 h prior to running the assay, in cell culture media (DMEM containing high Glucose and L-glutamine, 10% FBS, 1% Pen/Streptomycin, 1% Sodium Pyruvate, 2OmM HEPES, Zeocin 200mg/L), 100 μL of 1.3 * T0 6 /ml HEK 293 GPR73 (prokineticin 1 receptor) expressing cells were plated in a 96 well poly-d-lysine coated plate (Costar), and incubated at 37 C and 5% CO2. On the day in which the assay was run, the media was removed and 200 μL of 5X

Calcium Plus Dye (Molecular Devices) which was previously resuspended with 200 mL of assay buffer [HBSS w/ Ca 2+ and Mg 2+ w/o phenol red, 20 mM HEPES, 0.1% BSA, 10 mL probenecid (710 mg probenecid in 5 mL of /IN NaOH, to which was then added 5 mL HBSS containing 20 mM HEPES)] was added to each well of the 96-well plate. The plate was incubated at 37 C and

5% CU 2 for 30 min in dark. The plate was removed and allowed to reach RT for 15 min in the dark. The assay was then run on the FLlPR. In Brief: base line read for 1 min, compound added (25 μl_) and incubated for 4 min, 15 seconds, PK1 ligand preparation added (25 μL) for a final concentration of a previously determined EC 5 0 and fluorescence was counted for 1 min, 45 seconds. Baseline is described as the amount of relative fluorescence read when buffer alone is added to cells. Baseline was subtracted from all wells. Percent of control was calculated as follows:

(Baseline subtracted well value is divided by baseline subtracted max value) * 100. Percent inhibition is 100 minus the percent of control value.

The IC 50 is defined as the amount of a given compound required to inhibit 50% of the maximum signal that is generated by the concentration of PK1 preparation used in our assay. IC50 values were calculated using GraphPad Prism.

Biological Example 3 Effect ofPK1 on Secretion and Gut Mucosal Ion Transport in Mammals

Methodology. Segments of ileum starting at a point 2 cm proximal to the ileocecal junction and extending 10 cm proximally were freshly excised, placed

Into Krebs-Ringer bicarbonate (KRB) solution, and emptied of their contents as a plastic rod was gently inserted into the intact segment. Ileal segments were scored with the back-edge of scalpel blade along the entire mesenteric border, and the intact muscular layers including the myenteric plexus were carefully removed with flat-head forceps. Three rectangular tissue sheets approximately 1.5 cm in length were prepared from the remaining muscle-stripped, mucosa- submucosa tissues and cut with care taken to avoid Peyer * s patches. Each tissue sheet containing intact submucosal ganglia was pinned over a rectangular portal (total cross-sectional area of exposed mucosa = 0.50 cm 2 ) between halves of an acrylic mounting cassette that was inserted between the tissue-bathing reservoirs of a modified Ussing-type flux chamber (Physiologic Instruments, Inc., San Diego, CA).

The apical (i.e., mucosal) and basolateral (i.e., serosal) surface of each tissue was bathed with 6 ml of an oxygenated KRB solution maintained at 36 C. Once mounted, tissues were allowed to equilibrate for 0.5-1 h before electrical field stimulation and addition of secretagogues or drugs. The KRB solution contained (in mM) 120 NaCI, 6 KCI, 1.2 MgCI 2 , 1.2 NaH 2 PO 4 , 14.4 NaHCO 3 , 2.5 CaCI 2 , and 11.5 glucose or 11.5 mannitol. The KRB solution was continuously aerated with 95% O 2 : 5% CO 2 and maintained at pH 7.3. Each chamber was equipped with a pair of saturated KCI-agar bridges for measurement of transmural electrical potential difference (PD) across the tissue, and a pair of Ag- AgCI agar electrodes connected to an automated voltage-clamp device (model VCC MC6, or model VCC MC8, Physiologic Instruments, Inc., San Diego, CA) that compensated for solution resistance between the PD-sensing bridges and for deviations detected from a transmural potential difference (PD) across the tissues that were clamped at 0 mV. Tissue conductance (G) was calculated {in mS) by determining the current necessary to change PD by 1 mV using bipolar pulses from a pulse generator. Short-circuit current (Isc in μA), an index of net active ion transport, was measured continuously. Tissue conductance (Gt in mS), an index of the barrier function to passive flow of ions, was calculated from changes in Isc and the transepithelial potential difference for each tissue.

Baseline recordings of short-circuit current (Isc) and G for each tissue were acquired and recorded for an additional 15 min period prior to the start of an experimental protocol. Stimulated changes in Isc were measured and recorded continuously with a computerized data acquisition system (PowerLab 8SP, ADlnstruments, Inc., Colorado Springs, CO). Neurally-evoked changes in Isc were obtained by application of electrical field stimulation (80V, 0.5 ms, 10 Hz, 5 s) from the outputs of an electronic stimulator (S-48, Grass-Telefactor, Astro-Med, Inc., West Warwick, Rl) attached via aluminum foil electrodes placed in direct contact with the mucosal surface at opposite poles of each tissue. Pharmacological agents and secretagogues were routinely added to the basolateral-side reservoir. Agonist or secretagogue effects on Isc were continuously recorded following basolateral addition. Concentration-response curves were constructed from the cumulative, step-wise addition of predetermined increasing amounts of agonist or secretagogue that were added at or near the peak Isc response to the preceding lower concentration. Effects of antagonists or inhibitors of secretion were evaluated after a 10-20 minute exposure period that was followed by challenge with a specific agonist or secretagogue.

Statistical Analysis. All values are reported as means + SE. Electrophysiological data obtained with Ussing flux-type chambers were normalized to tissue surface area and expressed per cm 2 . Stimulated changes in ion transport were determined as the absolute difference between a baseline value prior to stimulation and the maximal response (δlsc) evoked by a given stimulus or secretagogue. An estimated EC 5 Q for the stimulatory action of PK1 on epithelial secretion was determined from a 7-point cumulative concentration- response test using a computer calculated curve-fitting function in PRISM (GraphPad Software, Inc.). An unpaired, two-tailed Student's t-test was used to determine statistical significance between any two groups, e.g., control and experimental tissues. An ANOVA in conjunction with a post hoc Neuman-Keuls multiple comparisons test was used to determine significant differences among multiple groups. P < 0.05 was considered statistically significant.

Summary of results. The basal lsc was 35.2 + 2.4 μA/cm 2 and tissue conductance (G) was 33.7 + 0.9 mS/cm 2 (n = 79 tissues from 34 rats). Following a single-dose addition of PK1 to the Krebs solution bathing the basolateral tissue surface, lsc gradually increased to a peak value within 2-4 min and then declined back toward baseline within 10-15 min. The PK1- evoked increases in lsc were concentration dependent with an ECso of approximately 8.2 nM determined from cumulative concentration-response studies (see Fig. 2). The maximal response for the PK1 -evoked response occurred at 100 nM; 100 nM PK1 evoked an increase in lsc of 28.7 + 2.9 μA/cm 2 from baseline (n = 42 tissues from 29 rats) and 10 nM PK1 evoked an increase of 13.5 + 2. μA/cm 2 (n = 33 tissues from 22 rats). The concentrations of 10 nM and 100 nM were used in all subsequent studies. PK1 had no significant effect on G in any of our studies. The pro-secretory effect of PK1 was not blocked in the presence of the nerve conduction toxin, Tetrodotoxin (TTX), or blockade of muscarinic receptors present on mucosal enterocytes by the anti-cholinergic drug, Atropine, indicating that the its action is not dependent on intrinsic neural activity in the tissues. The PK1 evoked increase in lsc requires the presence of endogenous PK1 receptors since exogenous PK1 peptide added to ileum mucosal tissues from PK1 receptor knock-out mice failed to elicit a significant change in lsc compared to wild-type littermates.

Methodology. The basic methodology for Ussing-type ion flux chambers used in these studies was the same as that described in detail above with the following modifications to the experimental protocol. Following a 30-45 minute equilibration period, baseline-stable tissues were subjected to a train of electrical field stimulation (EFS; 80 V, 0.5 ms, 10 Hz, 5 s) applied from contacts connecting the foil electrodes on opposite poles of the tissue to the polarized, isolated

outputs from an electronic square-pulse stimulator. The responses to two sequential EFS were used to gauge tissue viability and comparability of the responses of individual tissues from each rat and between rats. Tissue conductance was measured at periodic intervals as changes in the amplitudes of brief short-circuit current responses evoked by application of 1 mV amplitude- bipolar pulses from a pulse generator using Ohm's Law. Three to four tissues from each rat were studied. The tissues from a given animal were grouped and assigned accordingly: one control tissue which received only vehicle followed by two consecutive doses of PK- 1 lϊgand added in a cumulative fashion to the basolateral surface of the tissue; the remaining two to three tissues from the same animal were assigned to be exposed to a given PK-1 receptor antagonist (e.g., 3-4 tissues from 1 rat: Control, Antagonist i, Antagonist 2 , and/or Antagonist 3 ). Test compound was added to the basolateral tissue side reservoir at a final concentration of 1 μM and allowed a 15 minute incubation period prior to challenge with the PK1 peptide. At the end of this 15 min exposure period, PK1 ligand at 10 and 100 nM was added in a cumulative fashion to each tissue to characterize the inhibitory effect of the test compound. At the conclusion of the experiment, EFS was re-applied to gauge tissue viability and stability of responsiveness. For the Cholera toxin studies, paired mucosal tissues were obtained from each rat and mounted in Ussing-type chambers. Following tissue equilibration, baseline-stable and conductance-stable tissues were exposed to 1 μg/ml Cholera toxin (i.e., one tissue from each pair) added to the mucosa together with simultaneous addition of DMSO vehicle or Compound 3 of the present invention (i.e., one tissue from each pair) to the serosa at a final concentration of 10 μM to start the experiment. From this point on, baseline lsc and periodic assessment of tissue conductance were monitored and recorded for up to 4 hours.

Summary of results. Pre-treatment of tissues with PK1 antagonists alone had no measurable effect on baseline lsc and tissue conductance (G). The results indicate that suppression of the PK1 evoked increase in lsc in isolated rat ileum mucosa was successfully achieved in the presence of Compound 3 of the

present invention, which was identified using a functional cell based screening assay (i.e., mobilization of intracellular Ca 2+ ) as a putative antagonist at the PK1 receptor. In trials with this compound, the observed suppression of the lsc response evoked by two ascending cumulative concentrations of PK1 showed characteristics of a significant surmountable antagonism (see Fig. 3). These data strongly suggest that good efficacy can be achieved in the selective functional blockade of the PK1 receptor by this small molecule inhibitor to modulate the pro-secretory effect of PK1 on the intestinal epithelium. The selectivity of the functional blockade of the PK1 receptor by Compound 3 was confirmed by testing this compound against an unrelated cholinergic secretagogue, carbachol. Compound 3 failed to suppress the pro-secretory effect of carbachol tested at two different concentrations added in an ascending cumulative fashion to the serosal side of each tissue in the Ussing-type flux chambers (see Fig. 4). To investigate the potential anti-secretory efficacy of selective small molecule PK1 receptor antagonists, we established a model of secretory diarrhea ex vivo in the Ussing-type flux chambers with mucosal exposure to Cholera toxin. Mucosal application of Cholera toxin mimics the route of exposure for this disease-causing agent in animals and man. Pre-treatment of isolated rat ileum mucosa with Compound 3 (10 μM added to the serosa), did significantly suppress the sustained increase in baseline lsc over time evoked by 1 μg/ml Cholera toxin added to the mucosa by approximately 50-60% (see Fig.5). These data suggest the potential for the efficacious use of PK1 receptor antagonists from this chemical class in gut disease states that have a significant secretory diarrhea component.
