Description: CXCR3 ANTAGONISTS CROSS-REFERENCES TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional applications Serial Nos. 60/255,241, filed December 11, 2000 and 60/296,499, filed June 6, 2001, the disclosures of each being incorporated herein by reference. BACKGROUND OF THE INVENTION Chemokines are chemotactic cytokines that are released by a wide variety of cells to attract macrophages, T cells, eosinophils, basophils and neutrophils to sites of inflammation (reviewed in Schall, Cytokine, 3:165-183 (1991), Schall, et al, Curr. Opin. Immunol, 6:865-873 (1994) and Murphy, Rev. Immun., 12:593-633 (1994)). In addition to stimulating chemotaxis, other changes can be selectively induced by chemokines in responsive cells, including changes in cell shape, transient rises in the concentration of intracellular free calcium ions ([Ca 2+ ])„ granule exocytosis, integrin upregulation, formation of bioactive lipids (e.g., leukotrienes) and respiratory burst, associated with leukocyte activation. Thus, the chemokines are early triggers of the inflammatory response, causing inflammatory mediator release, chemotaxis and extravasation to sites of infection or inflammation. There are four classes of chemokines, CXC (α), CC (β), C(γ), and CX C (δ), depending on whether the first two cysteines are separated by a single amino acid (C- X-C), are adjacent (C-C), have a missing cysteine pair (C), or are separated by three amino acids (CXC 3 ). The α-chemokines, such as interleukin-8 (IL-8), melanoma growth stimulatory activity protein (MGSA), and stromal cell derived factor 1 (SDF-1) are chemotactic primarily for neutrophils and lymphocytes, whereas β-chemokines, such as RANTES, MlP-lα, MlP-lβ, monocyte chemotactic protein- 1 (MCP-1), MCP-2, MCP-3 and eotaxin are chemotactic for macrophages, T-cells, eosinophils and basophils (Deng, et al, Nature, 381:661-666 (1996)). The C chemokine lymphotactin shows specificity for lymphocytes (Kelner, et al, Science, 266:1395-1399 (1994)) while the CX 3 C chemokine fractalkine shows specificity for lymphocytes and monocytes (Bazan, et al, Nature, 385:640-644 (1997). Chemokines bind specific cell-surface receptors belonging to the family of G-protein-coupled seven-transmembrane-domain proteins (reviewed in Horuk, Trends Pharm. Sci., 15:159-165 (1994)) termed "chemokine receptors." On binding their cognate ligands, chemokine receptors transduce an intracellular signal through the associated heterotrimeric G protein, resulting in a rapid increase in intracellular calcium concentration. There are at least twelve human chemokine receptors that bind or respond to β-chemokines with the following characteristic pattern: CCR1 (or "CKR-1" or "CC- CKR-1") MlP-lα, MlP-lβ, MCP-3, RANTES (Ben-Barruch, et al, J. Biol. Chem., 270:22123-22128 (1995); Neote, et al, Cell, 72:415-425 (1993)); CCR2A and CCR2B (or "CKR-2 A"/"CKR-2A" or "CC-CKR-2 A"/"CC-CKR2 A") MCP- 1 , MCP-3 , MCP-4; CCR3 (or "CKR-3" or "CC-CKR-3") eotaxin, RANTES, MCP; (Ponath, et al, J. Exp. Med., 183:2437-2448 (1996)); CCR4 (or "CKR-4" or "CC-CKR-4") TARC, MDC (Imai, et al,. J. Biol. Chem., 273:1764-1768 (1998)); CCR5 (or "CKR-5" or "CC-CKR-5") MIP- lα, RANTES, MlP-lβ (Sanson, et al, Biochemistry, 35:3362-3367 (1996)); CCR6 MIP- 3 alpha (Greaves, et al, J. Exp. Med, 186:837-844 (1997)); CCR7 MIP-3 beta and 6Ckine (Campbell, et α/., J Cell. Biol, 141:1053-1059(1998)); CCR8 1-309, HHV8 vMIP-I, HHV-8 vMIP-II, MCV vMCC-I (Dairaghi, et al, J. Biol. Chem., 274:21569- 21574 (1999)); CCR9 TECK (Zaballos, et al, J. Immunol, 162:5671-5675 (1999)), D6 MIP-1 beta, RANTES, and MCP-3 (Nibbs, et al, J. Biol. Chem., 272:32078-32083 (1997)), and the Duffy blood-group antigen RANTES, MCP-1 (Chaudhun, et al, J. Biol Chem., 269:7835-7838 (1994)). Chemokine receptors, such as CCR1, CCR2, CCR2A, CCR2B, CCR3, CCR4, CCR5, CCR6, CCR7, CCR8, CCR9, CXCR1, CXCR2, CXCR3, CXCR4, CXCR5, CX 3 CR1, and XCR1 have been implicated as being important mediators of inflammatory and immunoregulatory disorders and diseases, including asthma and allergic diseases, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis. The CXCR3 chemokine receptor is expressed primarily in T lymphocytes, and its functional activity can be measured by cytosolic calcium elevation or chemotaxis. The receptor was previously referred to as GPR9 or CKR-L2. Its chromosomal location is unusual among the chemokine receptors in being localized to Xql3. Ligands that have been identified that are selective and of high affinity are the CXC chemokines, IP 10, MIG and ITAC. The highly selective expression of CXCR3 makes it an ideal target for intervention to interrupt inappropriate T cell trafficking. The clinical indications for such intervention are in T-cell mediated autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and type I diabetes. Inappropriate T-cell infiltration also occurs in psoriasis and other pathogenic skin inflammation conditions, although the diseases may not be true autoimmune disorders. In this regard, up-regulation of IP- 10 expression in keratinocytes is a common feature in cutaneous immunopathologies. Inhibition of CXCR3 can be beneficial in reducing rejection in organ transplantation. Ectopic expression of CXCR3 in certain tumors, especially subsets of B cell malignancies indicate that selective inhibitors of CXCR3 will have value in tumor immunotherapy, particularly attenuation of metastasis. In view of the clinical importance of CXCR3, the identification of compounds that modulate CXCR3 function represents an attractive avenue into the development of new therapeutic agents. Such compounds are provided herein.

DETAILED DESCRIPTION OF THE INVENTION Definitions The term "alkyl," by itself or as part of another substituent, means, unless otherwise stated, a straight or branched chain, or cyclic hydrocarbon radical, or combination thereof, which may be fully saturated, mono- or polyunsaturated and can include di- and multivalent radicals, having the number of carbon atoms designated (i.e. C I -C I Q means one to ten carbons). Examples of saturated hydrocarbon radicals include groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, t-butyl, isobutyl, sec-butyl, cyclohexyl, (cyclohexyl)methyl, cyclopropylmethyl, homologs and isomers of, for example, n-pentyl, n-hexyl, n-heptyl, n-octyl, and the like. An unsaturated alkyl group is one having one or more double bonds or triple bonds. Examples of unsaturated alkyl groups include vinyl, 2-propenyl, crotyl, 2-isopentenyl, 2-(butadienyl), 2,4-pentadienyl, 3-(l,4-pentadienyl), ethynyl, 1- and 3-propynyl, 3-butynyl, and the higher homologs and isomers. The term "alkylene" by itself or as part of another substituent means a divalent radical derived from an alkane, as exemplified by -CH 2 CH 2 CH 2 CH 2 -, and further includes those groups described below as "heteroalkylene." Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, with those groups having 10 or fewer carbon atoms being preferred in the present invention. A "lower alkyl" or "lower alkylene" is a shorter chain alkyl or alkylene group, generally having eight or fewer carbon atoms, or more. The terms "alkoxy," "alkylamino" and "alkylthio" (or thioalkoxy) are used in their conventional sense, and refer to those alkyl groups attached to the remainder of the molecule via an oxygen atom, an amino group, or a sulfur atom, respectively. Similarly, the term dialkylamino refers to an amino group having two attached alkyl groups that can be the same or different. The term "heteroalkyl," by itself or in combination with another term, means, unless otherwise stated, a stable straight or branched chain, or cyclic hydrocarbon radical, or combinations thereof, consisting of the stated number of carbon atoms and from one to three heteroatoms selected from the group consisting of O, N, Si and S, and wherein the nitrogen and sulfur atoms may optionally be oxidized and the nitrogen heteroatom may optionally be quatemized. The heteroatom(s) O, N and S may be placed at any interior position of the heteroalkyl group. The heteroatom Si may be placed at any position of the heteroalkyl group, including the position at which the alkyl group is attached to the remainder of the molecule. Examples include -CH 2 -CH 2 -O-CH 3 , -CH 2 - CH 2 -NH-CH 3 , -CH 2 -CH 2 -N(CH 3 )-CH 3 , -CH 2 -S-CH 2 -CH 3 , -CH 2 -CH 2 ,-S(O)-CH 3 , -CH 2 - CH 2 -S(O) 2 -CH 3 , -CH=CH-O-CH 3 , -Si(CH 3 ) 3 , -CH 2 -CH=N-OCH 3 , and -CH=CH-N(CH 3 )- CH 3 . Up to two heteroatoms may be consecutive, such as, for example, -CH 2 -NH-OCH 3 and -CH 2 -O-Si(CH 3 ) . When a prefix such as (C 2 -C 8 ) is used to refer to a heteroalkyl group, the number of carbons (2-8, in this example) is meant to include the heteroatoms as well. For example, a C 2 -heteroalkyl group is meant to include, for example, -CH 2 OH (one carbon atom and one heteroatom replacing a carbon atom) and -CH 2 SH. The term "heteroalkylene" by itself or as part of another substituent means a divalent radical derived from heteroalkyl, as exemplified by -CH2-CH 2 -S-CH 2 CH 2 - and -CH 2 -S-CH 2 - CH 2 -NH-CH 2 -. For heteroalkylene groups, heteroatoms can also occupy either or both of the chain termini (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, and the like). Still further, for alkylene and heteroalkylene linking groups, no orientation of the linking group is implied. The terms "cycloalkyl" and "heterocycloalkyl", by themselves or in combination with other terms, represent, unless otherwise stated, cyclic versions of "alkyl" and "heteroalkyl", respectively. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule. Examples of cycloalkyl include cyclopentyl, cyclohexyl, 1-cyclohexenyl, 3- cyclohexenyl, cycloheptyl, and the like. Examples of heterocycloalkyl include 1 -(1,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-morpholinyl, 3- morpholinyl, tetrahydrofuran-2-yl, tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3-yl, 1 -piperazinyl, 2-piperazinyl, and the like. The terms "halo" or "halogen," by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as "haloalkyl," are meant to include monohaloalkyl and polyhaloalkyl. For example, the term "halo(Cι-C )alkyl" is mean to include trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like. The term "aryl" means, unless otherwise stated, a polyunsaturated, typically aromatic, hydrocarbon substituent which can be a single ring or multiple rings (up to three rings) which are fused together or linked covalently. The term "heteroaryl" refers to aryl groups (or rings) that contain from zero to four heteroatoms selected from N, O, and S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. A heteroaryl group can be attached to the remainder of the molecule through a heteroatom. Non-limiting examples of aryl and heteroaryl groups include phenyl, 1-naphthyl, 2-naphthyl, 4-biphenyl, 1 -pyrrolyl, 2- pyrrolyl, 3-pyrrolyl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl, pyrazinyl, 2-oxazolyl, 4- oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2- thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-fiιryl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl, 3- pyridyl, 4-pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-benzimidazolyl, 5-indolyl, 1-isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6- quinolyl. Substituents for each of the above noted aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. For brevity, the term "aryl" when used in combination with other terms (e.g., aryloxy, arylthioxy, arylalkyl) includes both aryl and heteroaryl rings as defined above. Thus, the term "arylalkyl" is meant to include those radicals in which an aryl group is attached to an alkyl group (e.g., benzyl, phenethyl, pyridylmethyl and the like) including those alkyl groups in which a carbon atom (e.g., a methylene group) has been replaced by, for example, an oxygen atom (e.g., phenoxymethyl, 2-pyridyloxymethyl, 3- (l-naphthyloxy)propyl, and the like). Each of the above terms (e.g., "alkyl," "heteroalkyl," "aryl" and "heteroaryl") are meant to include both substituted and unsubstituted forms of the indicated radical. Preferred substituents for each type of radical are provided below. Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be a variety of groups selected from: -OR', =O, =NR\ =N-OR', -NR'R", -SR', -halogen, -SiR'R"R'", -OC(O)R', -C(O)R', -CO 2 R\ -CONR'R", -OC(O)NR'R", -NR"C(O)R', -NR'- C(O)NR"R"\ -NR"C(O) 2 R\ -NH-C(NH 2 )=NH, -NR'C(NH 2 )=NH, -NH-C(NH 2 )=NR\ - S(O)R\ -S(O) 2 R', -S(O) 2 NR'R", -CN and -NO 2 in a number ranging from zero to (2m'+l), where m' is the total number of carbon atoms in such radical. R', R" and R'" each independently refer to H, unsubstituted (Cι-C 8 )alkyl and heteroalkyl, unsubstituted aryl, aryl substituted with 1-3 halogens, alkoxy or thioalkoxy groups, or aryl-(C 1 -C 4 )alkyl groups. When R' and R" are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 5-, 6-, or 7-membered ring. For example, -NR'R" is meant to include 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term "alkyl" in its broadest sense is meant to include groups such as haloalkyl (e.g., -CF and -CH 2 CF ) and acyl (e.g., -C(O)CH 3 , -C(O)CF 3 , -C(O)CH 2 OCH 3 , and the like). Preferably, the alkyl groups will have from 0-3 substituents, more preferably 0, 1, or 2 substituents, unless otherwise specified. Similarly, substituents for the aryl and heteroaryl groups are varied and are selected from: -halogen, -OR', -OC(O)R', -NR'R", -SR', -R', -CN, -NO 2 , -CO 2 R\ -CONR'R", -C(O)R', -OC(O)NR'R", -NR"C(O)R', -NR"C(O) 2 R', ,-NR'-C(O)NR"R'", -NH-C(NH 2 )=NH, -NR'C(NH 2 )=NH, -NH-C(NH 2 )=NR', -S(O)R', -S(O) 2 R', -S(O) 2 NR'R", -N 3 , -CH(Ph) 2 , ρerfluoro(Cι-C 4 )alkoxy, and perfluoro(C 1 -C 4 )alkyl, in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R\ R" and R'" are independently selected from H, (Cι-C 8 )alkyl and heteroalkyl, unsubstituted aryl and heteroaryl, (unsubstituted aryl)-(Cι-C 4 )alkyl, and (unsubstituted aryl)oxy-(C ι -C 4 )alkyl. Two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -T-C(O)-(CH 2 ) q -U-, wherein T and U are independently -NH-, -O-, -CH 2 - or a single bond, and q is an integer of from 0 to 2. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -A-(CH 2 ) r -B-, wherein A and B are independently -CH 2 -, -O-, -NH-, -S-, -S(O)-, -S(O) 2 -, -S(O) 2 NR'- or a single bond, and r is an integer of from 1 to 3. One of the single bonds of the new ring so formed may optionally be replaced with a double bond. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -(CH 2 ) s -X-(CH 2 )t-, where s and t are independently integers of from 0 to 3, and X is -O-, -NR'-, -S-, -S(O)-, -S(O) 2 -, or -S(O) 2 NR'-. The substituent R' in -NR'- and -S(O) 2 NR'- is selected from hydrogen or unsubstituted (Ci- C 6 )alkyl. As used herein, the term "heteroatom" is meant to include oxygen (O), nitrogen (N), sulfur (S) and silicon (Si). The term "pharmaceutically acceptable salts" is meant to include salts of the active compounds which are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds of the present invention contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present invention contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge, et al. (1977) J. Pharm. Sci. 66:1-19). Certain specific compounds of the present invention contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts. (1) The terms "treat", "treating" or "treatment", as used herein, refer to a method of alleviating or abrogating a disease and/or its attendant symptoms. The terms "prevent", "preventing" or "prevention", as used herein, refer to a method of barring a subject from acquiring a disease. The neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of the present invention. In addition to salt forms, the present invention provides compounds which are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present invention. Additionally, prodrugs can be converted to the compounds of the present invention by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the present invention when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug.

Methods of Use In yet another aspect, the present invention provides methods of treating CXCR3 -mediated conditions or diseases by administering to a subject having such a disease or condition, a therapeutically effective amount of a compound or composition of the invention. The "subject" is defined herein to include animals such as mammals, including , but not limited to, primates (e.g., humans), cows, sheep, goats, horses, dogs, cats, rabbits, rats, mice and the like. As used herein, the phrase "CXCR3-mediated condition or disease" and related phrases and terms refer to a condition characterized by inappropriate, e.g., less than or greater than normal, CXCR3 activity. Inappropriate CXCR3 activity might arise as the result of CXCR3 expression in cells which normally do not express CXCR3, increased CXCR3 expression (leading to, e.g., inflammatory and immunoregulatory disorders and diseases), or, decreased CXCR3 expression (leading to, e.g., certain cancers and angiogenic and vasculogenic-related disorders). Inappropriate CXCR3 functional activity might arise as the result of CXCR3 expression in cells which normally do not express CXCR3, increased CXCR3 expression (leading to, e.g., inflammatory and immunoregulatory disorders and diseases) or decreased CXCR3 expression. Inappropriate CXCR3 functional activity might also arise as the result of chemokine secretion by cells which normally do not secrete a CXC chemokine, increased chemokine expression (leading to, e.g., inflammatory and immunoregulatory disorders and diseases) or decreased chemokine expression. A CXCR3 -mediated condition or disease may be completely or partially mediated by inappropriate CXCR3 functional activity. However, a CXCR3 -mediated condition or disease is one in which modulation of CXCR3 results in some effect on the underlying condition or disease (e.g., a CXCR3 antagonist results in some improvement in patient well-being in at least some patients). The term "therapeutically effective amount" means the amount of the subject compound that will elicit the biological or medical response of a tissue, system, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician or that is sufficient to prevent development of or alleviate to some extent one or more of the symptoms of the disease being treated. Diseases and conditions associated with inflammation, infection and cancer can be treated with the present compounds and compositions. In one group of embodiments, diseases or conditions, including chronic diseases, of humans or other species can be treated with inhibitors of CXCR3 function. These diseases or conditions include: (1) inflammatory or allergic diseases such as systemic anaphylaxis or hypersensitivity responses, drug allergies, insect sting allergies and food allergies; inflammatory bowel diseases, such as Crohn's disease, ulcerative colitis, ileitis and enteritis; vaginitis; psoriasis and inflammatory dermatoses such as dermatitis, eczema, atopic dermatitis, allergic contact dermatitis, urticaria; vascuhtis; spondyloarthropathies; scleroderma; asthma and respiratory allergic diseases such as allergic rhinitis, hypersensitivity lung diseases, and the like, (2) autoimmune diseases, such as arthritis (rheumatoid and psoriatic), multiple sclerosis, systemic lupus erythematosus, type I diabetes, glomerulonephritis, and the like, (3) graft rejection (including allograft rejection and graft-v-host disease) and conditions associated therewith, and (4) other diseases in which undesired inflammatory responses are to be inhibited, e.g-., atherosclerosis, myositis, neurodegenerative diseases (e.g., Alzheimer's disease), encephalitis, meningitis, hepatitis, nephritis, sepsis, sarcoidosis, conjunctivitis, otitis, chronic obstructive pulmonary disease, sinusitis and Behcet's syndrome. In another group of embodiments, diseases or conditions are treated with agonists of CXCR3 function. Examples of diseases to be treated with CXCR3 agonists include cancers, diseases in which angiogenesis or neovascularization play a role (neoplastic diseases, retinopathy and macular degeneration), infectious diseases and immunosuppressive diseases. Preferably, the present methods are directed to the treatment or prevention of diseases or conditions selected from neurodegenerative diseases (e.g., Alzheimer's disease), multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, atherosclerosis, encephalitis, meningitis, hepatitis, nephritis, sepsis, sarcoidosis, psoriasis, eczema, uticaria, type I diabetes, asthma, conjunctivitis, otitis, allergic rhinitis, chronic obstructive pulmonary disease, sinusitis, dermatitis, inflammatory bowel disease, ulcerative colitis, Crohn's disease, Behcet's syndrome, gout, cancer, viral infections (e.g., HIV), bacterial infections, and organ transplant conditions or skin transplant conditions. The term "organ transplant conditions" is meant to include bone marrow transplant conditions and solid organ (e.g., kidney, liver, lung, heart, pancreas or combination thereof) transplant conditions. Diseases or conditions that can be treated with the present compounds and compositions include diseases commonly associated with (1) inflammatory or allergic diseases, (2) autoimmune diseases, (3) graft rejection and (4) other diseases in which undesired inflammatory responses are to be inhibited, as described above. For example, restenosis following a procedure such as balloon angioplasty, is commonly associated with atherosclerosis and can be treated with the present compounds and compositions. Depending on the disease to be treated and the subject's condition, the compounds of the present invention may be administered by oral, parenteral (e.g., intramuscular, intraperitoneal, intravenous, ICV, intracisternal injection or infusion, subcutaneous injection, or implant), inhalation spray, nasal, vaginal, rectal, sublingual, or topical routes of administration and may be formulated, alone or together, in suitable dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles appropriate for each route of administration. In the treatment or prevention of conditions which require chemokine receptor modulation an appropriate dosage level will generally be about 0.001 to 100 mg per kg patient body weight per day which can be administered in single or multiple doses. Preferably, the dosage level will be about 0.01 to about 25 mg/kg per day; more preferably about 0.05 to about 10 mg/kg per day. A suitable dosage level may be about 0.01 to 25 mg/kg per day, about 0.05 to 10 mg/kg per day, or about 0.1 to 5 mg/kg per day. Within this range the dosage may be 0.005 to 0.05, 0.05 to 0.5 or 0.5 to 5.0 mg/kg per day. For oral administration, the compositions are preferably provided in the form of tablets containing 1.0 to 1000 milligrams of the active ingredient, particularly 1.0, 5.0, 10.0, 15.0. 20.0, 25.0, 50.0, 75.0, 100.0, 150.0, 200.0, 250.0, 300.0, 400.0, 500.0, 600.0, 750.0, 800.0, 900.0, and 1000.0 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. The compounds may be administered on a regimen of 1 to 4 times per day, preferably once or twice per day. It will be understood, however, that the specific dose level and frequency of dosage for any particular patient may be varied and will depend upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of that compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the host undergoing therapy. The compounds of the present invention can be combined with other compounds having related utilities to treat or prevent inflammatory and immune disorders and diseases, including asthma and allergic diseases, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis, and those pathologies noted above. In many instances, compositions which include a compound of the invention and an alternative or second therapeutic agent have additive or synergistic effects when administered. For example, in the treatment or prevention of inflammation, the present compounds may be used in conjunction or combination with an antiinflammatory or analgesic agent such as an opiate agonist, a lipoxygenase inhibitor, such as an inhibitor of 5-lipoxygenase, a cyclooxygenase inhibitor, such as a cyclooxygenase-2 inhibitor, an interleukin inhibitor, such as an interleukin-1 inhibitor, an NMD A antagonist, an inhibitor of nitric oxide or an inhibitor of the synthesis of nitric oxide, a non-steroidal antiinflammatory agent, or a cytokine-suppressing antiinflammatory agent, for example with a compound such as acetaminophen, aspirin, codiene, fentanyl, ibuprofen, indomethacin, ketorolac, morphine, naproxen, phenacetin, piroxicam, a steroidal analgesic, sufentanyl, sunlindac, tenidap, and the like.

Likewise, compounds of the present invention may be used in combination with other drugs that are used in the treatment/prevention/suppression or amelioration of the diseases or conditions for which compounds of the present invention are useful. Such other drugs may be administered, by a route and in an amount commonly used therefor, contemporaneously or sequentially with a compound of the present invention. When a compound of the present invention is used contemporaneously with one or more other drugs, a pharmaceutical composition containing such other drugs in addition to the compound of the present invention is prefened. Accordingly, the pharmaceutical compositions of the present invention include those that also contain one or more other active ingredients, in addition to a compound of the present invention.

The weight ratio of the compound of the present invention to the second active ingredient may be varied and will depend upon the effective dose of each ingredient. Generally, an effective dose of each will be used. Thus, for example, when a compound of the present invention is combined with an NSAID the weight ratio of the compound of the present invention to the NSAID will generally range from about 1000:1 to about 1 : 1000, preferably about 200:1 to about 1:200. Combinations of a compound of the present invention and other active ingredients will generally also be within the aforementioned range, but in each case, an effective dose of each active ingredient should be used. Immunosuppressants within the scope of the present invention further include, but are not limited to, leflunomide, RAD001, ERL080, FTY720, CTLA-4, antibody therapies such as orthoclone (OKT3), daclizumab (Zenapax®) and basiliximab (Simulect®), and antithymocyte globulins such as thymoglobulins.

When used in combination, the practitioner can administer a combination of the therapeutic agents, or administration can be sequential. In still other particularly prefened embodiments, the present methods are directed to the treatment or prevention of rheumatoid arthritis, wherein the compound of the invention is administered either alone or in combination with a second therapeutic agent selected from the group consisting of methotrexate, sulfasalazine, hydroxychloroquine, cyclosporine A, D-penicillamine, infiiximab (Remicade®), etanercept (Enbrel®), auranofin and aurothioglucose.

In yet another aspect, the present invention includes methods to evaluate putative specific agonists or antagonists of CXCR3 function. Accordingly, the present invention is directed to the use ofthese compounds in the preparation and execution of screening assays for compounds which modulate the activity of the CXCR3 chemokine receptor. For example, the compounds of this invention are useful for isolating receptor mutants, which are excellent screening tools for more potent compounds. Furthermore, the compounds of this invention are useful in establishing or determining the binding site of other compounds to the CXCR3 chemokine receptor, e.g., by competitive inhibition. The compounds of the instant invention are also useful for the evaluation of putative specific modulators of the CXCR3 chemokine receptor, relative to other chemokine receptors including CCR1, CCR2, CCR2A, CCR2B, CCR3, CCR4, CCR5, CCR6, CCR8, CCR10, CXCR3 and CXCR4,. One of skill in the art will appreciate that thorough evaluation of specific agonists and antagonists of the above chemokine receptors has been hampered by the lack of availability of non-peptidyl (metabolically resistant) compounds with high binding affinity for these receptors. Thus the compounds provided herein are particularly useful in this context. Combinatorial libraries of putative CXCR3 agonists or antagonists can be screened for pharmacological activity in in vitro or in vivo assays. Conventionally, new chemical entities with useful properties are generated by identifying a chemical compound (called a "lead compound") with some desirable property or activity, e.g., CXCR3 chemokine receptor modulation activity, creating variants of the lead compound, and evaluating the property and activity of those variant compounds. However, the cunent trend is to shorten the time scale for all aspects of drug discovery. Because of the ability to test large numbers quickly and efficiently, high throughput screening (HTS) methods are replacing conventional lead compound identification methods. In one preferred embodiment, high throughput screening methods involve providing a library containing a large number of potential therapeutic compounds (candidate compounds). Such "combinatorial chemical libraries" are then screened in one or more assays to identify those library members (particular chemical species or subclasses) that display a desired characteristic activity. The compounds thus identified can serve conventional "lead compounds" or can themselves be used as potential or actual therapeutics. A combinatorial chemical library is a collection of diverse chemical compounds generated by either chemical synthesis or biological synthesis by combining a number of chemical "building blocks" such as reagents. For example, a linear combinatorial chemical library, such as a polypeptide (e.g., mutein) library, is formed by combining a set of chemical building blocks called amino acids in every possible way for a given compound length (i.e., the number of amino acids in a polypeptide compound). Millions of chemical compounds can be synthesized through such combinatorial mixing of chemical building blocks (Gallop et. al. (1994) J. Med. Chem. 37(9):1233-1251). Preparation and screening of combinatorial chemical libraries is well known to those of skill in the art. Such combinatorial chemical libraries include, but are not limited to, peptide libraries (see, e.g., U.S. Patent No. 5,010,175, Furka (1991) Int. J. Pept. Prot. Res. 37:487-493, Houghton et. al. (1991) Nature 354: 84-88), peptoid libraries (PCT Publication No WO 91/19735), encoded peptide libraries (PCT Publication WO 93/20242), random bio-oligomer libraries (PCT Publication WO 92/00091), benzodiazepine libraries (U.S. Patent No. 5,288,514), libraries of diversomers, such as hydantoins, benzodiazepines and dipeptides (Hobbs et. al (1993) Proc. Nat. Acad. Sci. USA 90:6909-6913), vinylogous polypeptide libraries (Hagihara et al. (1992) J. Amer. Chem. Soc. 114:6568), libraries of nonpeptidyl peptidomimetics with a Beta-D-Glucose scaffolding (Hirschmann et al. (1992) J. Amer. Chem. Soc. 114:9217-9218), analogous organic syntheses of small compound libraries (Chen et. al. (1994) J. Am. Chem. Soc. 116:2661), oligocarbamate libraries (Cho et al. (1993) Science 261:1303) and/or peptidyl phosphonate libraries (Campbell et al (1994) J. Org. Chem. 59:658). See, generally, Gordon et al. (1994) J. Med. Chem. 37:1385-1401, nucleic acid libraries (.see, e.g., Stratagene Coφ.), peptide nucleic acid libraries (see, e.g., U.S. Patent No. 5,539,083), antibody libraries (see, e.g., Vaughn et. al. (1996) Nature Biotechnology 14(3):309-314), and PCT/US96/10287), carbohydrate libraries (see, e.g., Liang et al. (1996) Science 274:1520-1522, and U.S. Patent No. 5,593,853), and small organic molecule libraries (see, e.g., benzodiazepines, Baum (1993) C&EN Jan 18, page 33; isoprenoids, U.S. Patent No. 5,549,974; pynolidines, U.S. Patent Nos. 5,525,735 and 5,519,134; moφholino compounds, U.S. Patent No. 5,506,337; benzodiazepines, U.S. Patent No. 5,288,514; and the like). Devices for the preparation of combinatorial libraries are commercially available (see, e.g., 357 MPS, 390 MPS, Advanced Chem Tech, Louisville KY; Symphony, Rainin, Woburn MA; 433A Applied Biosystems, Foster City CA; 9050 Plus, Millipore, Bedford, MA). A number of well known robotic systems have also been developed for solution phase chemistries. These systems includes automated workstations like the automated synthesis apparatus developed by Takeda Chemical Industries, LTD. (Osaka, Japan) and many robotic systems utilizing robotic arms (Zymate II, Zymark Coφoration, Hopkinton MA; Orca, Hewlett-Packard, Palo Alto CA), which mimic the manual synthetic operations performed by a chemist. Any of the above devices are suitable for use with the present invention. The nature and implementation of modifications to these devices (if any) so that they can operate as discussed herein will be apparent to persons skilled in the relevant art. In addition, numerous combinatorial libraries are themselves commercially available (see e.g., ComGenex, Princeton NJ; Asinex, Moscow, Russia; Tripos, Inc., St. Louis MO; ChemStar, Ltd, Moscow, Russia; 3D Pharmaceuticals, Exton PA; Martek Biosciences, Columbia MD; etc.). High throughput assays for the presence, absence, quantification, or other properties of particular compounds may be used to test a combinatorial library that contains a large number of potential therapeutic compounds (potential modulator compounds). The assays are typically designed to screen large chemical libraries by automating the assay steps and providing compounds from any convenient source to assays, which are typically run in parallel (e.g., in microtiter formats on microtiter plates in robotic assays). Prefened assays detect enhancement or inhibition of CXCR3 receptor function. High throughput screening systems are commercially available (see e.g., Zymark Coφ., Hopkinton MA; Air Technical Industries, Mentor OH; Beckman Instruments, Inc., Fullerton CA; Precision Systems, Inc., Natick MA; etc.). These systems typically automate entire procedures, including all sample and reagent pipetting, liquid dispensing, timed incubations, and final readings of the microplate in detector(s) appropriate for the assay. These configurable systems provide high throughput and rapid start up as well as a high degree of flexibility and customization. The manufacturers of such systems provide detailed protocols for various high throughput systems. Thus, for example, Zymark Coφ. provides technical bulletins describing screening systems for detecting the modulation of gene transcription, ligand binding, and the like. EXAMPLES Reagents and solvents used below can be obtained from commercial sources such as Aldrich Chemical Co. (Milwaukee, Wisconsin, USA). Η-NMR spectra were recorded on a Varian Gemini 400 MHz NMR spectrometer. Significant peaks are tabulated in the order: number of protons, multiplicity (s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet; br s, broad singlet) and coupling constant(s) in Hertz (Hz). Electron Ionization (El) mass spectra were recorded on a Hewlett Packard 5989A mass spectrometer. Mass spectrometry results are reported as the ratio of mass over charge, followed by the relative abundance of each ion (in parentheses). In tables, a single m/e value is reported for the M+H (or, as noted, M-H) ion containing the most common atomic isotopes. Isotope patterns correspond to the expected formula in all cases. Electrospray ionization (ESI) mass spectrometry analysis was conducted on a Hewlett- Packard 1100 MSD electrospray mass spectrometer using the HP1 100 HPLC for sample delivery. Normally the analyte was dissolved in methanol at O.hng/mL and 1 microliter was infused with the delivery solvent into the mass spectrometer, which scanned from 100 to 1500 daltons. All compounds could be analyzed in the positive ESI mode, using 1:1 acetonitrile/water with 1% acetic acid as the delivery solvent. The compounds provided below could also be analyzed in the negative ESI mode, using 2mM NH 4 OAc in acetonitrile/water as delivery solvent.

The addition rate was slow enough to maintain internal temperature of the reaction below 38° C. Upon completed addition of the acid chloride, the heterogeneous reaction mixture was stined for 2.5 h at ambient temperature and then poured into 1600 mL water. The resulting water/DMF mixture, with white precipitate, was stined vigorously at ambient temperature for one h, after which time the solid was collected by vacuum filtration, rinsing the solid with cold water (2 x 100 mL).

Unless otherwise noted, all reagents used are available from commercial sources (e.g., Sigma). Test compounds are diluted in DMSO to a concentration that is 40- times the intended final assay concentration; 5 μL are transfened to each well of a 96- well flat-bottomed polypropylene plate (e.g., from Greiner, Inc.). CXCR3 -expressing cells obtained from ChemoCentryx were used in the assays to generate the data set forth in the Table provided in Figure 12. The cells were resuspended in assay buffer (25 mM Hepes, 80 mM NaCI, 1 mM CaCl 2 , 5 mM MgCl 2 , 0.2% bovine serum albumin, pH 7.1, stored at 4 °C) at 5 million cells per mL; 100 μL of this cell suspension is then transfened to each well of a 96-well plate containing the diluted test compounds. 125 I-labelled chemokine (purchased from commercial sources, e.g., Amersham, PE Life Sciences) is diluted in assay buffer to a concentration of approximately 60 pM; 100 μL of this chemokine solution is transfened to each well of a 96-well plate containing compounds and cell suspension. The plates are sealed with commercially available foil plate seals (e.g., from E&K Scientific), and stored at 4 °C for 2 to 4 h, shaking gently. At the end of this incubation period, the contents of the assay plates are transferred to GF/B filter plates (Packard) that have been pre-coated by dipping into a solution containing 0.3% polyethyleneimine (Sigma), using a cell harvester (Packard), and washing twice with wash buffer (25 mM Hepes, 500 mM NaCI, 1 mM CaCl 2 , 5 mM MgCl 2 , pH 7.1 , stored at room temperature). The filter plates are sealed on the bottom with plate seals (Packard), 50 μL of Microscint-20 scintillation fluid (Packard) is added to each well, and the top of the plates are sealed with clear plastic (TopSeal A, Packard). The plates are counted on a scintillation counter, such as a Packard TopCount. To measure non-specific binding, 4 wells containing unlabelled "cold" chemokine were included on each 96-well plate. To measure maximum binding, 4 wells containing 5 μL of DMSO, 100 μL of cell suspension and 100 μL of 125 I-labelled chemokine solution were included on each 96-well plate. Data were analyzed using commercially available software (e.g., Excel from Microsoft, Prism from GraphPad Software Inc.). Other assays may be used to identify compounds that modulate CXCR3 chemokine receptor activity, for example, binding assays (see, e.g., Weng et al. (1998) J. Biol Chem. 273:18288-18291, Campbell et al. (1998) J. Cell Biol. 141:1053-1059, Endres et al. (1999) J. Exp. Med. 189:1993-1998 and Ng et al. (1999) J. Med. Chem. 42:4680-4694), calcium flux assays (see, e.g., Wang et al. (2000) Mol Pharm.. 57:1190- 1198 and Rabin et al. (1999; J. Immunol. 162:3840-3850) and chemotaxis assays (see, e.g., Albanesi et al. (2000) J. Immunol. 165:1395-1402 and Loetscher et al. (1998; Ewr. J. Immunol. 28:3696-3705).
