FIELD OF THE INVENTION [002] Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments comprising such compounds, and methods of using such compounds to treat, prevent or diagnose diseases, disorders or conditions associated with prostaglandin D ₂ .

BACKGROUND OF THE INVENTION

[003] Prostaglandins are acidic lipids derived from the metabolism of arachidonic acid by the action of cyclooxygenase enzymes and downstream synthases. Prostaglandins have a diverse range of activities and have a well recognized role in pain and inflammation. Prostaglandin D ₂ (PGD ₂ ) is an acidic lipid mediator derived from the metabolism of arachidonic acid by cyclooxygenases and PGD ₂ synthases. PGD ₂ is produced by mast cells, macrophages and T _H 2 lymphocytes in response to local tissue damage as well as allergic inflammation in diseases such as asthma, rhinitis, and atopic dermatitis. Exogenous PGD ₂ applied to bronchial airways elucidates many characteristics of an asthmatic response suggesting that PGD ₂ plays an important pro-inflammatory role in allergic diseases. [004] PGD ₂ binds to a number of receptors, which include the thromboxane-type prostanoid (TP) receptor, PGD ₂ receptor (DP, also known as DP ₁ ) and chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2; also known as DP ₂ ). DP ₂ is associated with promoting chemotaxis and activation of T _H 2 lymphocytes, eosinophils and basophils. In particular, PGD ₂ binds to DP ₂ , and mediates its effects through a Gi-dependant elevation in calcium levels and reduction of intracellular cyclic AMP. In T _H 2 lymphocytes, IL4, IL5 and IL 13 cytokine production is stimulated. These cytokines have been implicated in numerous biological actions including, by way of example only, immunoglobulin E production, airway response, mucous secretion, and eosinophil recruitment.

SUMMARY OF THE INVENTION [005] Presented herein are compounds, pharmaceutical compositions and medicaments, methods, for (a) diagnosing, preventing, or treating allergic and non-allergic inflammation, (b)

mitigating adverse signs and symptoms that are associated with inflammation, and/or (c) controlling immunological, proliferative disorders. These disorders may arise from one or more of a genetic, iatrogenic, immunological, infectious, oncological, toxic, surgical, and/or traumatic etiology. In one aspect, the methods, compounds, pharmaceutical compositions, and medicaments described herein comprise antagonists of PGD ₂ receptors. In one aspect, the methods, compounds, pharmaceutical compositions, and medicaments described herein comprise antagonists of DP ₂ [006] In one aspect provided herein are compounds of Formula (I), Formula (II), Formula (III), Formula (IV), Formula (V), Formula (VI), Formula (VII), and Formula (VIII), pharmaceutically acceptable salts, pharmaceutically acceptable prodrugs, and pharmaceutically acceptable solvates thereof, which are anatgonists of DP ₂ , and are used to treat mammals suffering from one or more PGD _r dependent conditions or diseases, including, but not limited to, asthma, rhinitis, chronic obstructive pulmonary disease, pulmonary hypertension, interstitial lung fibrosis, arthritis, allergy, psoriasis, inflammatory bowel disease, adult respiratory distress syndrome, myocardial infarction, aneurysm, stroke, cancer, endotoxic shock, proliferative disorders and inflammatory conditions. In some embodiments, PGD ₂ -dependent conditions or diseases include those wherein an absolute or relative excess of PGD ₂ is present and/or observed. In one aspect, the mammal is a human.

DETAILED DESCRIPTION OF THE INVENTION [0160] Prostaglandin D ₂ (PGD ₂ ) is an acidic lipid derived from the metabolism of arachidonic acid by cyclooxygenases and PGD ₂ synthases. PGD ₂ is produced by mast cells, macrophages and T _H 2 lymphocytes in response to local tissue damage as well as in response allergic inflammation observed in diseases such as asthma, rhinitis, and atopic dermatitis. More specifically, exogenous PGD ₂ applied to bronchial airways elicits many responses that are characteristic of acute asthma. [0161] PGD ₂ is a major mast cell product that acts via two receptors, the D-type prostanoid (DP, also known as DP ₁ ) and the chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2, also known as DP ₂ ) receptors. DP ₂ mediates the chemotaxis of eosinophils, basophils, and Th2 lymphocytes, and DP ₁ receptor plays an important role in eosinophil trafficking. DP ₁ antagonists do not inhibit the release of eosinophils when induced by the DP ₂ - selective agonists. However, eosinophils in human bone marrow specimens express DPi and DP ₂ receptors at similar levels and human peripheral blood expresses both DPi and DP ₂ , but the DPi receptor is expressed at lower levels. In agreement with this, the chemotaxis of human peripheral blood eosinophils is inhibited by both DPj and DP ₂ antagonists. Accordingly, DP ₁ , DP ₂ and dual DP ₁ ZDP ₂ antagonists are useful in the treatment of allergic inflammation. [0162] Activation of DP ₂ is associated with chemotaxis and activation of T _H 2 lymphocytes, eosinophils and basophils. In particular, PGD ₂ binds to DP ₂ and mediates many of its effects

through a Gj-dependent elevation of intracellular calcium levels and reduction of cyclic AMP. In T _H 2 lymphocytes, IL4, IL5 and IL13 cytokine production are also stimulated by DP ₂ activation. These cytokines have been implicated in numerous biological actions including, by way of example only, immunoglobulin E production, airway response, mucous secretion, and eosinophil recruitment. [0163] The terms CRTH2 and DP ₂ , refer to the same receptor and are used interchangeably herein. Likewise, another common name for DP is DP], and the two terms are used interchangeably herein. Illustrative Biological Activity [0164] Prostaglandins (PGs) are recognized physiological lipid acid mediators produced by the release of arachidonic acid from cell membrane phospholipids and converted to prostaglandins by the action of COXi and COX ₂ cyclooxygenases and PG synthases. The cyclooxygenases sequentially convert arachidonic acid to cyclic endoperoxide prostaglandin G ₂ (PGG ₂ ) and subsequently, prostaglandin H ₂ (PGH ₂ ). Depending on the tissue, physiological signal, and/or synthase type, PGH ₂ can be converted to numerous different prostaglandins, such as PGE ₂ , PGD ₂ , PGF ₂ Ct, and PGI ₂ as well as thromboxane A ₂ , another eicosanoid signaling molecule. These mediators then elicit a wide variety of physiological responses including vasoconstriction or dilation, platelet aggregation, calcium transport, pain sensitization, hormone release, inflammatory and immune response, and cellular growth. [0165] Prostaglandin D ₂ is a major metabolite produced from the PGH ₂ intermediate via hematopoietic PGD ₂ synthase or lipocalin PGD ₂ synthase, hi the brain and central nervous system, PGD ₂ is produced and thought to Junction in pain perception and sleep regulation. In other tissues, PGD ₂ is produced primarily in immunoglobulin E (IgE) activated mast cells and to a lesser extent, in macrophages, dendritic cells, T helper 2 (T _H 2) lymphocytes and other leukocytes. In the cell, PGD ₂ is rapidly metabolized and converted to other downstream effectors including A ¹² PGJ ₂ , 9αl IpPGF ₂ , 13,14-dihydro-15-keto-PGD ₂ , and 15-deoxy-δ ^{12 14} PGD ₂ .. [0166] Mast-cell-derived PGD ₂ is produced in high concentrations in response to an allergen challenge. Studies in preclinical species have observed the following features when PGD ₂ is applied to in vivo preparations, or its overproduction is engineered by genetic manipulation: -Vasodilatation leading to erythema (flare) and -potentiation of oedema (wheal). -Recruitment of eosinophils and TH2 lymphocytes. -Modulation of TH2-cytokine production. -Bronchoconstriction. [0167] Injection of PGD ₂ into human skin has been shown to produce a long lasting erythema, to potentiate the effects of other mediators on induration and leukocyte infiltration in human skin and to enhance oedema formation in rat skin. It is most likely that these effects of PGD ₂ , like those of

other vasodilator prostaglandins, are due to an increased blood flow to the inflamed lesion and are, therefore, most likely to be mediated predominantly by the DPj receptor. Although these observations make it clear that DP ₁ mediates the vascular effects of PGD ₂ , the capacity of PGD ₂ to promote the cellular changes associated with inflammation is not due to an action on DPi. [0168] The main receptors that are activated by PGD ₂ or its metabolites and mediate its effects are DP ₁ , CRTH2 (or DP ₂ ) and TP. [0169] DPi (or DP) is a G-protein coupled seven-transmembrane receptor that, upon activation by PGD ₂ binding, leads to an increase in intracellular cAMP levels. DP _t is expressed in the brain, bronchial smooth muscle, vascular and airway smooth muscle, dendritic cells, and platelets and induces PGD ₂ dependent bronchodilation, vasodilation, platelet aggregation inhibition, and suppression of cytokine production. Genetic analysis of DPj function using knock-out mice has shown that mice lacking DP do not develop asthmatic responses in an ovalbumin-induced asthma model. Analysis of selective DP anatgonists in guinea pig allergic rhinitis models demonstrated dramatic inhibition of early nasal responses, as assessed by sneezing, mucosal plasma exudation and eosinophil infiltration. DP antagonism alleviates allergen-induced plasma exudation in the conjunctiva in a guinea pig allergic conjuctivitis model and antigen-induced esinophil infiltration into the lung in a guinea pig asthma model. [0170] Much of the pro-iriflarnmatory activity OfPGD ₂ is through interaction with DP ₂ (or CRTH2). DP ₂ is a G-protein coupled receptor and is typically highly expressed in T _H 2 lymphocytes, eosinophils and basophils. DP ₂ activation functions to directly activate and recruit T _H 2 lymphocytes and eosinophils. Activated T _H 2 lymphocytes produce and secrete inflammatory cytokines including RA, IL5, and ILl 3. Despite binding PGD ₂ with a similar affinity as DPi , DP ₂ is not structurally related to DPi and signals through a different mechanism- the effects OfDP ₂ are mediated through Gi-dependent elevation in intracellular calcium levels and reduction in intracellular levels of cyclic AMP. DP ₂ activation is important in eosinophil recruitment in response to allergic challenge in such tissues as nasal mucosa, bronchial airways, and skin. The application of either PGD ₂ or selective DP ₂ agonists both exacerbate and enhance allergic responses in lung and skin. DP ₂ activation appears to have a crucial role in mediating allergic responses, and thus the use of antagonists OfPGD ₂ activation of the DP ₂ receptor are an attractive approach to treat the inflammatory component of allergic diseases such as asthma, rhinitis, and dermatitis. [0171} TP receptors primarily function to antagonize DP ₁ receptor's effects such as promoting bronchoconstriction, vasoconstriction, and platelet aggregation. While TP receptor's main ligand is thromboxane A ₂ , it also binds and is activated by the PGD ₂ derivative, 9αl 1 βPGF ₂ . TP is a Gq- coupled prostanoid receptor that binds thromboxane with high affinity, promoting platelet aggregation and constriction of both vascular and airway smooth muscle. PGD ₂ activates the TP

receptor in human bronchial muscle, probably through the formation of the 11 -ketoreductase metabolite 9αl lβPGF2. The bronchoconstrictor effects of TP dominate over the bronchodilator effects of DPi in the airways. [0172] DP] and DP ₂ have crucial, and complementary, roles in the physiological response of animals to PGD ₂ and blockade of either one or both of these receptors may prove beneficial in alleviating allergic diseases or conditions triggered by PGD ₂ , such as, but not limited to, allergic rhinitis, asthma, dermatitis, and allergic conjunctivitis.

Synthesis of Compounds [0244] Compounds described in the prior section are synthesized using standard synthetic techniques or using methods known in the art in combination with methods described herein. In additions, solvents, temperatures and other reaction conditions presented herein may vary. [0245] The starting material used for the synthesis of the compounds described in the prior section are either synthesized or obtained from commercial sources, such as, but not limited to, Sigma-Aldrich, Fluka, Acros Organics, Alfa Aesar, and the like. The compounds described herein, and other related compounds having different substituents are synthesized using known techniques and materials, including those found in March, ADVANCED ORGANIC CHEMISTRY 4 ^th Ed., (Wiley 1992); Carey and Sundberg, ADVANCED ORGANIC CHEMISTRY 4 ^th Ed., VoIs. A and B (Plenum 2000, 2001), and Green and Wuts, PROTECTIVE GROUPS IN ORGANIC SYNTHESIS 3 ^rd Ed., (Wiley 1999). General methods for the preparation of compounds can be modified by the use of appropriate reagents and conditions for the introduction of the various moieties found in the formulae as provided herein. [0246] In certain embodiments, compounds described herein are prepared according to Scheme 1.

Scheme 1:

[0247] In one aspect, esters of phenyl acetic acids of structure I that have a halide group are reacted with a borylating agent using transition metal mediated reaction conditions to form boronate compounds of structure El. Boronate compounds of structure II are reacted with 2- halobenzaldehydes of structure III under palladium mediated coupling conditions to form biaryl aldehydes of structure IV. Biaryl aldehydes of structure IV are reacted with amines of strucutre V under reductive amination conditions to form amines of structure VI. Amines of strucutre VI are then reacted with acid chlorides of structure VII to form amides of structure VHI. The ester group of amides of structure VlIl is then hydrolyzed to form carboxylic acid compounds of structure IX. [0248] Other metal mediated coupling reactions to form biaryls include, but are not limited to Suzuki reactions, Stille cross couplings, Negishi couplings, Kumada couplings, Ullmann reactions, Hiyama Coupling, and variants thereof (Metal-Catalyzed Cross-Coupling Reactions, Armin de Meijere (Editor), Francois Diederich (Editor), John Wiley & Sons; 2nd edition, 2004; Ozdemir, et al., Tetrahedron, 2005, 61, 9791-9798 ; Ackermann, et al, Org.

[0251] Reaction of amines of structure VI with chloroformates of structure X provide carbamates, which after hydrolysis of the ester moiety, provide carbamates of structure XI. Methods for the preparation of carbamates include those found in, e.g., Greene, T. W. and Wuts, P.G.M "Protective Groups in Organic Synthesis", 3rd Edition, p.549, New York: Wiley, 1999. In one aspect, alkylamines (compounds of structure VI) are treated with phosgene or a phosgene equivalent, such as, for example, trichloromethyl chloroformate or carbonyldiimidazole, to yield an intemediate, which is then treated with a hydroxy containing compound R ¹⁵ -0H to provide carbamates of structure XI.

[0253] Reaction of benzylamines of structure XII with isocyanates or carbamoyl chlorides provides ureas of structure XII after hydrolysis of the ester group. Common methods for the synthesis of isocyanates include the Curtius rearrangement of acyl azides and the Lossen rearrangement of hydroxamic acids. [0254] The synthesis of sulfonamides of structure XIII is depicted in Scheme 3: Scheme 3:

[0255] Reaction of amines of structure VI with sulfonyl chlorides of structure XIV provides sulfonamides that are then treated with NaOH to provide sulfonamides of structure X1H. [0256] In the reactions described, it is necessary in certain embodiments to protect reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in the reactions. Protecting groups are used to block some or all reactive moieties and prevent such groups from participating in chemical reactions until the protective group is removed. In one embodiment, each protective group is removable by a different means. A detailed description of protecting groups and techniques applicable to the creation of protecting groups and their removal are described in Greene and Wuts, Protective Groups in Organic Synthesis, 3rd Ed., John Wiley & Sons, New York, NY, 1999, and Kocienski, Protective Groups, Thieme Verlag, New York, NY, 1994, which are incorporated herein by reference for such disclosure. Further Forms of Compounds [0257] In certain embodiments, compounds of any of Formula (I), Formula (IT), Formula (III), Formula (PV), Formula (V) Formula (VI), Formula (VII), or Formula (VTS) are prepared as a pharmaceutically acceptable acid addition salt (which is a type of a pharmaceutically acceptable salt) by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid, including, but not limited to, inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid metaphosphoric acid, and the like; and organic acids such as acetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, p-toluenesulfonic acid, tartaric acid, trifluoroacetic acid, citric acid, benzoic acid, 3- (4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, arylsulfonic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, 2-naphthalenesulfonic acid, 4-methylbicyclo-[2.2.2]oct-2-ene-1-carboxylic acid, glucoheptonic acid, 4,4'-methylenebis-(3-hydroxy-2-ene-l -carboxylic acid), 3- phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, and muconic acid. [0258] By "pharmaceutically acceptable," as used herein, refers to a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the compound, and is

relatively nontoxic, i.e., the material may be administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained. [0259] The term "pharmaceutically acceptable salt" refers to a formulation of a compound that does not cause significant irritation to an organism to which it is administered and does not abrogate the biological activity and properties of the compound. In some embodiments, pharmaceutically acceptable salts are obtained by reacting a compound of any of Formula (I), Formula (II), Formula (HI), Formula (IV), Formula (V), Formula (VI), Formula (VS), or Formula (Vπi) with acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid and the like. Pharmaceutically acceptable salts are also obtained by reacting a compound of any of Formula (I), Formula (D), Formula (HI), Formula (IV), Formula (V), Formula (VI), Formula (VII), or Formula (VIII) with a base to form a salt such as an ammonium salt, an alkali metal salt, such as a sodium or a potassium salt, an alkaline earth metal salt, such as a calcium or a magnesium salt, a salt of organic bases such as dicyclohexylamine, N-methyl-D-glucamine, tris(hydroxymethyl)methylamine, and salts with amino acids such as arginine, lysine, and the like. [0260] In other embodiments, compounds of any of Formula (I), Formula (H), Formula (DI), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (Vm) are prepared as a pharmaceutically acceptable salts by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base, including, but not limited to organic bases such as ethanolamine, diethanolamine, triethanolamine, tromethamine, ν-methylglucamine, and the like, or with an inorganic base such as aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, and the like. [0261] It should be understood that a reference to a pharmaceutically acceptable salt includes the solvent addition forms or crystal forms thereof, particularly solvates or polymorphs. Solvates contain either stoichiometric or non-stoichiometric amounts of a solvent, and are optionally formed during the process of crystallization with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Solvates of compounds of any of Formula (I), Formula (H), Formula (JE), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (VIII) are conveniently prepared or formed during the processes described herein. By way of example only, hydrates of compounds of any of Formula (T), Formula (H), Formula (III), Formula (TV), Formula (V) Formula (VI), Formula (VII), or Formula (VIII) are conveniently prepared by recrystallization from an aqueous/organic solvent mixture, using organic solvents including, but not limited to, dioxane, tetrahydrofuran, ethanol, or methanol. In addition, the compounds provided herein can exist in unsolvated as well as solvated forms. In general, the solvated forms are considered

equivalent to the unsolvated forms for the purposes of the compounds and methods provided herein. [02621 In yet other embodiments, the compounds of any of Formula (I), Formula (II), Formula (III), Formula (TV), Formula (V) Formula (VI), Formula (VII), or Formula (VIII) are prepared in various forms, including but not limited to, amorphous forms, milled forms and nano-particulate forms, In addition, compounds of any of Formula (I), Formula (II), Formula (III), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (VIII) include crystalline forms, also known as polymorphs. Polymorphs include the different crystal packing arrangements of the same elemental composition of a compound. Polymorphs usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Various factors such as the recrystallization solvent, rate of crystallization, and storage temperature may cause a single crystal form to dominate. [0263] In some embodiments, compounds of any of Formula (I), Formula (II), Formula (III), Formula (IV), Formula (V) Formula (VI), Formula (VIT), or Formula (V1H) are prepared as prodrugs. A "prodrug" refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. An example, without limitation, of a prodrug would be a compound of any of Formula (I), Formula (II), Formula (III), Formula (IV), Formula (V), Formula (VI), Formula (VII), or Formula (VET) which is administered as an ester (the "prodrug") to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. [0264] Prodrugs are generally drug precursors that, following administration to a subject and subsequent absorption, are converted to an active, or a more active species via some process, such as conversion by a metabolic pathway. Some prodrugs have a chemical group present on the prodrug that renders it less active and/or confers solubility or some other property to the drug. Once the chemical group has been cleaved and/or modified from the prodrug the active drug is generated. Prodrugs are often useful because, in some situations, they are easier to administer than the parent drug. In certain embodiments, the prodrug of a compound described herein is bioavailable by oral administration whereas the parent is not. Furthermore, in some embodiments, the prodrug of a compound described herein has improved solubility in pharmaceutical compositions over the parent drug.

[0265] In other embodiments, prodrugs are designed as reversible drug derivatives, for use as modifiers to enhance drug transport to site-specific tissues. In specific embodiments, the design of prodrugs to date is to increase the effective water solubility of the therapeutic compound for targeting to regions where water is the principal solvent.

Stella, Prodrugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series; and Edward B. Roche, Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987. [0266] Additionally, prodrug derivatives of compounds of any of Formula (T), Formula (II), Formula (HI), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (V1H) are prepared, if desired (e.g., for further details see Saulnier et al., (1994), Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985). By way of example only, in one aspect appropriate prodrugs are prepared by reacting a non-derivatized compound of any of Formula (I), Formula (II), Formula (IU), Formula (IV), Formula (V), Formula (VI), Formula (VS), or Formula (VIII) with a suitable carbamylating agent, such as, but not limited to, 1,1-acyloxyalkylcarbanochloridate, para- nitrophenyl carbonate, or the like. Prodrug forms of the herein described compounds, wherein the prodrug is metabolized in vivo to produce a derivative as set forth herein are included within the scope of the claims. Indeed, some of the herein-described compounds are a prodrug for another derivative or active compound. [0267] In some embodiments, sites on the aromatic ring portion of compounds of any of Formula (I), Formula (II), Formula (111), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (VIII) are susceptible to various metabolic reactions Therefore incorporation of appropriate substituents on the aromatic ring structures will reduce, minimize or eliminate this metabolic pathway. In specific embodiments, the appropriate substituent to decrease or eliminate the susceptibility of the aromatic ring to metabolic reactions is, by way of example only, a halogen, or an alkyl group.

[0268] In another embodiment, the compounds described herein are labeled isotopically (e.g. with a radioisotope) or by another other means, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels. [0269] In yet another embodiment, the compounds of any of Formula (I), Formula (II), Formula (in), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (VIII) possess one or more stereocenters and each center exists independently in either the R or S configuration. The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms as well as the appropriate mixtures thereof. In certain embodiments, compounds of any of Formula (I),

Formula (II), Formula (HI), Formula (IV), Formula (V) Formula (VI), Formula (VII), or Formula (Vπi) are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, resolution of enantiomers is carried out using covalent diastereomeric derivatives of the compounds described herein. In other embodiments, dissociable complexes are utilized (e.g., crystalline diastereomeric salts). Diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and are, in specific embodiments, separated by taking advantage of these dissimilarities. In these embodiments, the diastereomers are separated by chiral chromatography or by separation/resolution techniques based upon differences in solubility. The optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that does not result in racemization. Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers, Racemates and Resolutions", John Wiley and Sons, Inc., 1981. [0270] Additionally, in certain embodiments, the compounds provided herein exist as geometric isomers. The compounds and methods provided herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof. In some embodiments, the compounds described herein exist as tautomers. All tautomers are intended to be within the scope of the molecular formulas described herein. In additional embodiments of the compounds and methods provided herein, mixtures of enantiomers and/or diastereoisomers, resulting from a single preparative step, combination, or interconversion are envisioned.

Certain Pharmaceutical and Medical Terminology [0297] The term "acceptable" with respect to a formulation, composition or ingredient, as used herein, means having no persistent detrimental effect on the general health of the subject being treated. [0298} The term "modulate," as used herein, means to interact with a target either directly or indirectly so as to alter the activity of the target, including, by way of example only, to enhance the activity of the target, to inhibit the activity of the target, to limit the activity of the target, or to extend the activity of the target.

[0299] The term "modulator," as used herein, refers to a molecule that interacts with a target either directly or indirectly. The interactions include, but are not limited to, the interactions of an agonist, partial agonist, an inverse agonist and antagonist. In one embodiment, a modulator is an antagonist. [0300] The term "agonist," as used herein, refers to a molecule such as a compound, a drug, an enzyme activator or a hormone modulator that binds to a specific receptor and triggers a response in the cell. An agonist mimics the action of an endogenous ligand (such as prostaglandin, hormone or neurotransmitter) that binds to the same receptor. [0301] The term "antagonist," as used herein, refers to a molecule such as a compound, which diminishes, inhibits, or prevents the action of another molecule or the activity of a receptor site.

Antagonists include, but are not limited to, competitive antagonists, non-competitive antagonists, uncompetitive antagonists, partial agonists and inverse agonists.

[0302] Competitive antagonists reversibiy bind to receptors at the same binding site (active site) as the endogenous ligand or agonist, but without activating the receptor. [0303) Non-competitive antagonists (also known as allosteric antagonists) bind to a distinctly separate binding site from the agonist, exerting their action to that receptor via the other binding site. Non-competitive antagonists do not compete with agonists for binding. The bound antagonists may result in a decreased affinity of an agonist for that receptor, or alternatively may prevent conformational changes in the receptor required for receptor activation after the agonist binds. [0304] Uncompetitive antagonists differ from non-competitive antagonists in that they require receptor activation by an agonist before they can bind to a separate allosteric binding site. [0305] Partial agonists are defined as drugs which, at a given receptor, might differ in the amplitude of the functional response that they elicit after maximal receptor occupancy. Although they are agonists, partial agonists can act as a competitive antagonist if co-administered with a full agonist, as it competes with the full agonist for receptor occupancy and producing a net decrease in the receptor activation observed with the full agonist alone. [0306] An inverse agonist can have effects similar to an antagonist, but causes a distinct set of downstream biological responses. Constitutively active receptors which exhibit intrinsic or basal activity can have inverse agonists, which not only block the effects of binding agonists like a classical antagonist, but inhibit the basal activity of the receptor.

[0307] The term "PGD ₂ -dependent", as used herein, refers to conditions or disorders that would not occur, or would not occur to the same extent, in the absence OfPGD ₂ .

Methods of Dosing and Treatment Regimens

[0363] In one embodiment, the compound of any of Formula (I) ₅ Formula (II), Formula (III), Formula (IV), Formula (V), Formula (VI), Formula (VII), or Formula (VIII) are used in the preparation of medicaments for the treatment of PGD ₂ -dependent or PGD ₂ -mediated diseases or conditions. In addition, a method for treating any of the diseases or conditions described herein in a subject in need of such treatment, involves administration of pharmaceutical compositions containing at least one compound of any of Formula (I), Formula (II), Formula (III), Formula (FV), Formula (V), Formula (VT), Formula (VII), or Formula (V1H) or a pharmaceutically acceptable salt, pharmaceutically active metabolite, pharmaceutically acceptable prodrug, or pharmaceutically acceptable solvate thereof, in therapeutically effective amounts to said subject. [0364] In certain embodiments, the compositions containing the compound(s) described herein are administered for prophylactic and/or therapeutic treatments. In certain therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest the symptoms of the disease or condition. Amounts effective for this use depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician. Therapeutically effective amounts are optionally determined by methods including, but not limited to, a dose escalation clinical trial. [0365] In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a "prophylactically effective amount or dose." In this use, the precise amounts also depend on the patient's state of health, weight, and the like. When used in a patient, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician. [0366] In certain embodiments wherein the patient's condition does not improve, upon the doctor's discretion the administration of the compounds are administered chronically, that is, for an extended period of time, including throughout the duration of the patient's life in order to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition. [0367] hi certain embodiments wherein a patient's status does improve, administration of the compounds is given continuously; or, alternatively, the dose of drug being administered may be

temporarily reduced or temporarily suspended for a certain length of time (i.e., a "drug holiday"). In specific embodiments, the length of the drug holiday is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, and 365 days. The dose reduction during a drug holiday is, by way of example only, by 10%- 100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%. [0368] Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, in specific embodiments, the dosage or the frequency of administration, or both, is reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. In certain embodiments, however, the patient requires intermittent treatment on a long-term basis upon any recurrence of symptoms. [0369] The amount of a given agent that corresponds to such an amount varies depending upon factors such as the particular compound, disease condition and its severity, the identity (e.g., weight) of the subject or host in need of treatment, but can nevertheless be determined according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. In general, however, doses employed for adult human treatment are typically in the range of 0.02-5000 mg per day. In one aspect, the dose is in the range of 1-1500 mg per day, 1-500 mg per day, 1 -250 mg per day, or 1 -100 mg per day. In one embodiment, the desired dose is conveniently presented in a single dose or in divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.

In unit dosage form, the formulation is divided into unit doses containing appropriate quantities of one or more compound. In specific embodiments, the unit dosage is in the form of a package containing discrete quantities of the formulation. Non-limiting examples are packaged tablets or capsules, and powders in vials or ampoules. Aqueous suspension compositions are optionally packaged in single-dose non-re- closeable containers. Alternatively, multiple-dose re-closeable containers are used, in which case it is typical to include a preservative in the composition. By way of example only, formulations for parenteral injection are, in some embodiments, presented in unit dosage form, which include, but are not limited to ampoules, or in multi-dose containers, with an added preservative. [0371] In one embodiment, the daily dosages appropriate for the compound of any of Formula (I), Formula (II), Formula (III), Formula (IV), Formula (V), Formula (VI), Formula (VII), or Formula

(Vπi) described herein are from about 0.01 to about 10 mg/kg per body weight. In specific embodiments, an indicated daily dosage in a large mammal, including, but not limited to, humans, is in the range from about 0.5 mg to about 1000 mg, conveniently administered in divided doses, including, but not limited to, up to four times a day or in extended release form. In certain embodiments, suitable unit dosage forms for oral administration comprise from about 1 to 500 mg active ingredient, from about 1 to 250 mg active ingredient, or from about 1 to 100 mg active ingredient. In other embodiments, the daily dosage or the amount of active in the dosage form are lower or higher than the ranges indicated herein, based on a number of variables in regard to an individual treatment regime. In various embodiments, the daily and unit dosages are altered depending on a number of variables including, but not limited to, the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner. [0372J Toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD ₅₀ (the dose lethal to 50% of the population) and the ED ₅₀ (the dose therapeutically effective in 50% of the population). The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD ₅₀ and ED ₅₀ . m certain embodiments, the data obtained from cell culture assays and animal studies are used in formulating the therapeutically effective daily dosage range and/or the therapeutically effective unit dosage amount for use in mammals, including humans, hi some embodiments, the daily dosage amount of the compounds described herein lies within a range of circulating concentrations that include the ED ₅₀ with minimal toxicity. In certain embodiments, the daily dosage range and/or the unit dosage amount varies within this range depending upon the dosage form employed and the route of administration utilized.

[0401] In certain embodiments, different therapeutically-effective dosages of the compounds disclosed herein will be utilized in formulating pharmaceutical composition and/or in treatment regimens when the compounds disclosed herein are administered in combination with one or more additional agent, such as an additional therapeutically effective drug, an adjuvant or the like. Therapeutically-effective dosages of drugs and other agents for use in combination treatment regimens can be determined by means similar to those set forth hereinabove for the actives themselves. Furthermore, the methods of prevention/treatment described herein encompasses the use of metronomic dosing, i.e., providing more frequent, lower doses in order to minimize toxic side effects. In some embodiments, a combination treatment regimen encompasses treatment regimens in which administration of a DP ₂ antagonist described herein is initiated prior to, during, or after treatment with a second agent described above, and continues until any time during treatment with the second agent or after termination of treatment with the second agent. It also

includes treatments in which a DP ₂ antagonist described herein and the second agent being used in combination are administered simultaneously or at different times and/or at decreasing or increasing intervals during the treatment period. Combination treatment further includes periodic treatments that start and stop at various times to assist with the clinical management of the patient. For example, in one embodiment, a DP ₂ antagonist described herein in the combination treatment is administered weekly at the onset of treatment, decreasing to biweekly, and decreasing further as appropriate. [0402] Compositions and methods for combination therapy are provided herein. In accordance with one aspect, the pharmaceutical compositions disclosed herein are used to treat PGD ₂ - dependent or PGD ₂ mediated conditions. In accordance with another aspect, the pharmaceutical compositions disclosed herein are used to treat respiratory diseases (e.g., asthma), where treatment with a DP ₂ antagonist is indicated and to induce bronchodilation in a subject. In one embodiment, the pharmaceutical compositions disclosed herein are used to treat airways or nasal inflammation diseases such as asthma and rhinitis. [0403] In one embodiment, pharmaceutical compositions disclosed herein are used to treat a subject suffering from a vascular inflammation-driven disorder. In one embodiment, the pharmaceutical compositions disclosed herein are used to treat skin inflammation diseases such as atopic dermatitis. [0404] In certain embodiments, combination therapies described herein are used as part of a specific treatment regimen intended to provide a beneficial effect from the co-action of a DP ₂ described herein and a concurrent treatment. It is understood that the dosage regimen to treat, prevent, or ameliorate the condition^) for which relief is sought, is modified in accordance with a variety of factors. These factors include the type of respiratory disorder and the type of bronchoconstriction or inflammation from which the subject suffers, as well as the age, weight, sex, diet, and medical condition of the subject. Thus, in some instances, the dosage regimen actually employed varies and, in some embodiments, deviates from the dosage regimens set forth herein. [0405] For combination therapies described herein, dosages of the co-administered compounds vary depending on the type of co-drug employed, on the specific drug employed, on the disease or condition being treated and so forth. In additional embodiments, when co-administered with one or more biologically active agents, the compound provided herein is administered either simultaneously with the biologically active agent(s), or sequentially. If administered sequentially, the attending physician decides on the appropriate sequence of administering protein in combination with the biologically active agent(s). [0406] In combination therapies, the multiple therapeutic agents (one of which is one of the compounds described herein) are administered in any order or even simultaneously. If

administration is simultaneous, the multiple therapeutic agents are, by way of example only, provided in a single, unified form, or in multiple forms (e.g., as a single pill or as two separate pills). In one embodiment, one of the therapeutic agents is given in multiple doses, and in another, two (or more if present) are given as multiple doses. In some embodiments of non-simultaneous administration, the timing between the multiple doses vary from more than zero weeks to less than four weeks. In addition, the combination methods, compositions and formulations are not to be limited to the use of only two agents; the use of multiple therapeutic combinations is also envisioned. [0407J In additional embodiments, the DP ₂ antagonist described herein are used in combination with procedures that provide additional or synergistic benefit to the patient. By way of example only, patients are expected to find therapeutic and/or prophylactic benefit in the methods described herein, wherein DP ₂ antagonists described herein, and/or combinations with other therapeutics are combined with genetic testing to determine whether that individual is a carrier of a mutant gene that is known to be correlated with certain diseases or conditions. [0408] The DP ₂ antagonist described herein, and combination therapies, are administered before, during or after the occurrence of a disease or condition, and the timing of administering the composition containing a compound varies. Thus, in one embodiment, the compounds described herein are used as a prophylactic and are administered continuously to subjects with a propensity to develop conditions or diseases in order to prevent the occurrence of the disease or condition. In another embodiment, the compounds and compositions are administered to a subject during or as soon as possible after the onset of the symptoms. The administration of the compounds are initiated within the first 48 hours of the onset of the symptoms, preferably within the first 48 hours of the onset of the symptoms, more preferably within the first 6 hours of the onset of the symptoms, and most preferably within 3 hours of the onset of the symptoms. The initial administration is accomplished via any practical route, such as, for example, by intravenous injection, a bolus injection, infusion over 5 minutes to about 5 hours, a pill, a capsule, transdermal patch, buccal delivery, and the like, or combination thereof. In specific embodiments, a compound described herein is administered as soon as is practicable after the onset of a disease or condition is detected or suspected, and for a length of time necessary for the treatment of the disease, such as, for example, from about 1 month to about 3 months. In some embodiments, the length required for effective treatment varies, and the treatment length is adjusted to suit the specific needs of each subject. For example, in specific embodiments, a compound described herein or a formulation containing the compound is administered for at least 2 weeks, about 1 month to about 5 years, or from about 1 month to about 3 years.

[0409] By way of example, therapies which combine DP ₂ antagonists described herein with inhibitors of PGD ₂ synthesis or PGD ₂ receptor antagonists, either acting at the same or other points

in the PGD ₂ synthesis pathway, are encompassed herein for treating PGD ₂ -dependent or PGD ₂ mediated diseases or conditions. In addition, by way of example, encompassed herein are therapies that combine DP ₂ antagonists described herein with inhibitors of inflammation for treating PGD ₂ - dependent or PGD ₂ mediated diseases or conditions. [0410] In another embodiment described herein, methods for treatment of PGD ₂ -dependent or PGD ₂ mediated conditions or diseases include administration to a patient compounds, pharmaceutical compositions, or medicaments described herein in combination with an antiinflammatory agent including, but not limited to, non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids (glucocorticoids).

Chem., 2007, 50, 794-806 and Cheng et al, PNAS, 2006 Apr 25;103(17):6682-7.) and S-5751 (Arimura et al, J. Pharmacol. Exp. Ther., 2001 Aug; 298(2):411-9). For some patients, the most appropriate formulation or method of use of such combination treatments depends on the type OfPGD ₂ - dependent or PGD ₂ mediated disorder, the time period in which the DP ₂ antagonist acts to treat the disorder and/or the time period in which the DPi receptor antagonist acts to prevent DPi receptor activity. By way of example only, some embodiments described herein provide for such combination treatments that are used for treating a patient suffering from respiratory disorders such as asthma and rhinitis. [0416] In another embodiment described herein, methods for treatment of PGD ₂ -dependent or PGD ₂ mediated conditions or diseases includes administering to a patient compounds, pharmaceutical compositions, or medicaments described herein in combination with a TP receptor antagonist.

[0417] In one embodiment, the co-administration of a DP ₂ receptor antagonist with a DPi receptor antagonist or a TP receptor antagonist has therapeutic benefit over and above the benefit derived from the administration of a either a DP ₂ antagonist, DPi antagonist or a TP antagonist alone. In the case that substantial inhibition Of PGD ₂ activity has undesired effects, partial inhibition of this

pathway through the amelioration of the effects of the proinflammatory agonists combined with the block of the DPi receptor, TP receptor and/or DP ₂ receptor may afford substantial therapeutic benefits, particularly for respiratory diseases.

CHO cells stably expressing the recombinant human CRTH2 receptor are resuspended in 10 mM Hepes, 7.4 containing 1 mM DTT, lysed and centrifuged at 75,000 xg to pellet the membranes. The membranes are resuspended in 10 mM Hepes, 7.4 containing 1 mM DTT and 10% glycerol. Membranes (-12.5 μg per well) are incubated in 96-well plates with 0.05 nM [ ³⁵ S]-GTPyS, 80 nM PGD ₂ , 5 μM GDP, and test compound in Assay Buffer (50 mM Hepes, pH 7.4, 100 mM NaCl, 5 mM MgCl ₂ and 0.2% human serum albumin) for 60 minutes at 3O°C. The reactions are terminated by rapid filtration through Whatman GF/B glass fibre filter plates. The filter plates are washed 3 times with 1 ml cold Assay Buffer and dried. Scintillant is then added to the plates and the radioactivity retained on the filters is determined on a Packard TopCount (Perkin Elmer). Specific binding is determined as total radioactive binding minus non-

specific binding in the absence of the ligand (80 nM PGD ₂ ). IC ₅₀ S were determined using

Graphpad prism analysis of drug titration curves.

Example 230c: Whole Blood Esoinophil Shape Change Assay

[01114] Blood is drawn from consenting human volunteers in EDTA vacutainer tubes and used within 1 hr of draw. A 98 μl aliquot of blood is mixed with 2 μl of test compound (in 50% DMSO) in 1.2 ml polypropylene tubes. The blood is vortexed and incubated at 37°C for 15 minutes. 5 μl of 1 μM PGD ₂ in PBS is added for a final concentration of 50 nM and the tubes briefly vortexed. The reactions are incubated for exactly 5 minutes at 37°C and then terminated by placing the tubes on ice and immediately adding 250 μl of ice-cold 1 :4 diluted Cytofix (BD Biosciences). The reactions are transferred to 12 x 75 mM polystyrene round bottom tubes and the red blood cells lysed by the addition of 3 ml ammonium chloride lysing solution (150 mM NH ₄ Cl, 10 mM KHCO ₃ , 0.1 mM EDTA disodium salt) and incubation at room temperature for 15 minutes. The cells are pelleted by spinning at 1300 rpm for 5 minutes at 4°C and washed once with 3 ml ice-cold PBS. The cells are resuspended in 0.2 ml of ice-cold 1 :4 diluted Cytofix (BD Biosciences) and analyzed on a FACSCalibur (BD Biosciences) within 2 hours. Eosinophils were gated on the basis of autofluorescence in the FL2 channel and shape change on 500 eosinophils was assayed by forward scatter and side scatter analysis. The specific change in shape induced by PGD ₂ was calculated as the difference between the percentage of high forward scatter eosinophils in the presence and absence of PGD ₂ . IC ₅₀ S were determined using Graphpad Prism® analysis of drug titration curves. Example 23Od: DPi binding assay [01115] The ability of a compound to bind to the human DPI receptor was evaluated via a radioligand membrane binding assay using the DPi selective synthetic ligand [ ³ H]BWA868 C. Packed human platelets (Biological Specialty Corporation), were resuspended in 6 volumes of Hepes/HBSS buffer (10 mM Hepes, 1 mM DTT in Hanks Balanced Salt Solution (HBSS)), lysed and centrifuged at 75,000 xg to pellet the membranes. Membranes were resuspended in Hepes/HBSS buffer to approximately 12 mg protein/ml. Membranes (20 μg protein/well) are incubated in 96-well plates with 2 nM [ ³ H]BWA868 C and test compound in Assay Buffer (50 mM Hepes, 10 mM MnCl ₂ , 1 mM EDTA, plus or minus 0.2% human serum albumin, pH 7.4) for 60 minutes at room temperature. The reactions are terminated by rapid filtration through Whatman GF/C glass fibre filter plates. The filter plates were pre-soaked in 0.33% polemylenimine for 30 minutes at room temperature then washed in Wash Buffer (50 mM Hepes, 0.5 M NaCl pH 7.4) prior to harvesting. After harvesting, the filter plates are washed 3 times with 1 ml cold Wash Buffer then dried. Scintillant is then added to the plates and the radioactivity retained on the filters is determined on a Packard TopCount (Perkin Elmer). Specific binding is determined as total radioactive binding minus non-specific binding in the presence of 10 μM BW A868C. IC ₅₀ S were determined using GraphPad prism analysis of drug titration curves.

Methods were adapted from those detailed in Nakaya, M., et al.. 2006. Noninvasive system for evaluating allergen-induced nasal hypersensitivity in murine allergic rhinitis. Laboratory Investigation, 86:917-926. Female BALB/c mice (20-25g) are immunized by an intraperitoneal injection (i.p.) of 2 μg ovalbumin (OVA) complexed with alum in a volume 0.2 ml on days 0 and 14. Seven days later (day 21) mice are challenged intranasally with 20 μl of a lOmg/ml solution of OVA. The challenge period occurs daily from days 21 to day 25. Mice (5-7/group) are randomly assigned to receive either compound or vehicle and are treated by oral gavage 1 -2 hour prior to each OVA challenge. The number of sneezes and nasal rubs are counted by an independent blind observe during a period of 8 minutes immediately following OVA challenge on days 21, 23 and 25. A significant increase in allergen-induced sneezing and nasal rubbing occurs over the 5-day challenge period. Inhibition of this effect by select compounds is determined statistically using Graphpad prism.

Example 232: Guinea Pig IV-DKPGD2-induced peripheral blood leukocyte influx [01117] The compounds ability to inhibit leukocyte migration in vivo was assessed using intravenous injection of 13,14-dihydro-15-keto-prostaglandin D2 (DK-PGD2). Methods were adapted from those detailed Shichijo et al., 2003, Chemoattractant receptor-homologous molecule expressed on Th2 cells activation in vivo increases blood leukocyte counts and its blockade abrogates 13, 14-dihydro-15-keto-prostaglandin D2-induced eosinophilia hi rats. Journal of Pharmacology and Experimental Therapeutics, 307:518-525. Male Hartley guinea pigs were immunized with ovalbumin (OVA) on day 0 by intraperitoneal (TP) injection of 1 ml of a 100 μg/ml solution in Imject Alum. They were then used in the DK-PGD2 procedure between days 14 and 21. Subjects were randomly assigned to receive either vehicle (0.5% methyl cellulose, 4 ml/kg, oral (PO)) or one of three to four doses of test compound. Two hours or eighteen hours after dosing, animals were anesthetized with ketamine and challenged with DK-PGD2 (1 mg/kg, IV). Thirty minutes after IV administration, blood was collected via the marginal ear vein into EDTA tubes for cell analysis. 10 μl blood was lysed in 190 μl water followed by a further 20-fold dilution in PBS. A 10 μl fraction was mixed with equal parts trypan blue and loaded on a hemocytometer. Cells were visualized at a magnification of 4OX using a LabPro light microscope and totals counted and recorded. Cells are expressed as total cells x 10 ⁸ per ml of blood. Inhibition of this effect by select compounds is determined statistically using Graphpad prism.
