Description: PIPERIDINE CCR-3 RECEPTOR ANTAGONISTS This invention relates to certain piperidine quaternary salts that are CCR-3 receptor antagonists, pharmaceutical compositions containing them, methods for their use and methods for preparing these compounds. Tissue eosinophilia is a feature of a number of pathological conditions such as asthma, rhinitis, eczema and parasitic infections ((see Bousquet, J. et al. N. Eng. J. Med. 323: 1033-1039 (1990) and Kay, A.B. and Corrigan. C.J. Br. Med. Bull. 48:51-64 (1992)). In asthma, eosinophil accumulation and activation are associated with damage to bronchial epithelium and hyperresponsiveness to constrictor mediators. Chemokines such as RANTES, eotaxin and MCP-3 are known to activate eosinophils ((see Baggiolini, M. and Dahinden, CA. Immunol. Today. 15:127-133 (1994), Rot, A. M. et al. J. Exp. Med. 176, 1489-1495 (1992) and Ponath. P.D. et al. J. Clin. Invest., Vol. 97, #3, 604-612 (1996)). However, unlike RANTES and MCP-3 which also induce the migration of other leukocyte cell types, eotaxin is selectively chemotactic for eosinophils ((see Griffith- Johnson, D.A et al. Biochem. Biophy. Res. Commun. 197: 1167 (1993) and Jose, P.J. et al. Biochem. Biophy. Res. Commun. 207, 788 (1994)). Specific eosinophil accumulation was observed at the site of administration of eotaxin whether by intradermal or intraperitoneal injection or aerosol inhalation ((see Griffith-Johnson, D.A et al. Biochem. Biophy. Res. Commun. 197: 1167 (1993); Jose, P.J. et al. J. Exp. Med. 179, 881-887 (1994); Rothenberg, M.E. et al. J. Exp. Med. 181, 1211 (1995) and Ponath. P.D. /. Clin. Invest., Vol. 97, #3, 604-612 (1996)). Glucocorticoids such as dexamethasone, methprednisolone and hydrocortisone have been used for treating many eosinophil-related disorders, including bronchial asthma ((R. P. Schleimer et. al., Am . Rev. Respir. Dis., 141, 559 (1990)). The glucocorticoids are believed to inhibit LL-5, LL-3 mediated eosinophil survival in these diseases. However, prolonged use of glucocorticoids can lead to side effects such as glaucoma, osteoporosis and growth retardation in the patients ((see Hanania N.A et al., J. Allergy and Clin. Immunol, Vol. 96, 571-579 (1995) and Saha M. T. et al, Ada Paediatήca, Vol. 86, #2, 138-142 (1997)). It is therefore desirable to have an alternative means of treating eosinophil related diseases without incurring these undesirable side effects. Recently, the CCR-3 receptor was identified as a major chemokine receptor that eosinophils use for their response to eotaxin, RANTES and MCP-3. When transfected into a murine pre-β lymphoma line, CCR-3 bound eotaxin, RANTES and MCP-3 and conferred chemotactic responses on these cells to eotaxin, RANTES and MCP-3 ((see Ponath. P.D. et al. J. Exp. Med. 183, 2437-2448 (1996)). The CCR-3 receptor is expressed on the surface of eosinophils, T-cells (subtype Th-2), basophils and mast cells and is highly selective for eotaxin. Studies have shown that pretreatment of eosinophils with an anti-CCR-3 mAb completely inhibits eosinophil chemotaxis to eotaxin, RANTES and MCP-3 ((see Heath H. et al. J. Clin. Invest., Vol. 99, #2, 178-184 (1997)). WO 98/04554 discloses piperidine analogs that are CCR-3 receptor antagonists. Blocking the ability of the CCR-3 receptor to bind RANTES, MCP-3 and eotaxin and thereby preventing the recruitment of eosinophils should provide for the treatment of eosinophil-mediated inflammatory diseases. The present invention therefore concerns novel piperidine quaternary salts which are capable of inhibiting the binding of eotaxin to the CCR-3 receptor and thereby provide a means of combating eosinophil induced diseases, such as asthma.

Compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed "isomers". Isomers that differ in the arrangement of their atoms in space are termed "stereoisomers". Stereoisomers that are not mirror images of one another are termed "diastereomers" and those that are non-superimposable mirror images of each other are termed "enantiomers". When a compound has an asymmetric center, for example, where a carbon atom is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and 5-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a "racemic mixture". The compounds of this invention may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)- stereoisomers or as mixtures thereof. For example, if the R 3 and R 4 substituents in a compound of Formula (I) are different, then the carbon to which they are attached is an asymmetric center and the compound of Formula (I) can exist as an (R)~ or (S)-stereoisomer. Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers and mixtures, racemic or otherwise, thereof. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art (see discussion in Chapter 4 of "Advanced Organic Chemistry", 4th edition J. March, John Wiley and Sons, New York, 1992). A "pharmaceutically acceptable excipient" means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes an excipient that is acceptable for veterinary use as well as human pharmaceutical use. "A pharmaceutically acceptable excipient" as used in the specification and claims includes both one and more than one such excipient. A "pharmaceutically acceptable counterion" means an ion having a charge opposite to that of the substance with which it is associated and that is pharmaceutically acceptable. Representative examples include, but are not limited to, chloride, bromide, iodide, methanesulfonate, p-tolylsulfonate, trifluoroacetate, acetate, and the like. A "pharmaceutically acceptable salt" of a compound means a salt that is pharmaceutically acceptable and that possesses the desired pharmacological activity of the parent compound. Such salts include: (1) acid addition salts, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like; or formed with 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, tartaric acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)-benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2- napthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, 4-methylbicyclo[2.2.2]oct-2-ene-l-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, hydroxynapthoic acid, salicylic acid, stearic acid, muconic acid, and the like; or (2) salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base such as ethanolamine, diethanolamine, triethanolamine, tromethamine, N-methylglucamine, and the like. "Leaving group" has the meaning conventionally associated with it in synthetic organic chemistry i.e., an atom or group capable of being displaced by a nucleophile and includes halogen, alkanesulfonyloxy, arenesulfonyloxy, ester, or amino such as chloro, bromo, iodo, mesyloxy, tosyloxy, trifluorosulfonyloxy, methoxy, N,O- dimethylhydroxyl-amino, and the like. "Pro-drugs" means any compound which releases an active parent drug according to Formula (I) in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of Formula (I) are prepared by modifying functional groups present in the compound of Formula (I) in such a way that the modifications may be cleaved in vivo to release the parent compound. Prodrugs include compounds of Formula (I) wherein a hydroxy, sulfhydryl or amino group in compound (I) is bonded to any group that may be cleaved in vivo to regenerate the free hydroxyl, amino, or sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to esters (e.g., acetate, formate, and benzoate derivatives), carbamates (e.g., N.N- dimethylaminocarbonyl) of hydroxy functional groups in compounds of Formula (I), and the like. "Treating" or "treatment" of a disease includes: (1) preventing the disease, i.e. causing the clinical symptoms of the disease not to develop in a mammal that may be exposed to or predisposed to the disease but does not yet experience or display symptoms of the disease, (2) inhibiting the disease, i.e., arresting or reducing the development of the disease or its clinical symptoms, or (3) relieving the disease, i.e., causing regression of the disease or its clinical symptoms. A "therapeutically effective amount" means the amount of a compound that, when administered to a mammal for treating a disease, is sufficient to effect such treatment for the disease. The "therapeutically effective amount" will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated.

Synthesis of Compounds of Formula (I) In general, compounds of Formula (I) where m, R, R 1 , R 2 , R 3 , R 4 , R 5 , Q, Ar and Ar 1 are as defined above in its broadest sense are prepared by converting aminoalkyl derivatives of Formulae LT(a-b) and carboxyalkyl derivatives of Formulae LT(c-d) to a compound of Formula (la) which is then converted to the quartemary salt of Formula (I) as shown in Fig. 1 below. Synthesis of compounds of Formulae LI (a-d) and their conversion to compounds of Formulae (la) and (I) are described in detail in Schemes A-J below. Synthesis of compounds of Formulae LΙ(a-d) Preparation of Compounds of Formula (Ηa) A compound of Formula (TJa) where T is nitrogen, m is at least 1 and R, R , R " , R 3 , R 4 , R 6 , Q and Ar 1 are as defined in their broadest sense above is prepared as illustrated in Scheme A below. Scheme A In general, compounds of Formula (TJa) are prepared in two steps by first converting a compound of formula 1 to an N-protected aminoalkyl derivative of formula 2, followed by removal of the amino protecting group in 2, as described in detail below. An N-protected aminoalkyl derivative of formula 2 [where PG is an amino protecting group (e.g., tert-butoxycarbonyl (BOC), benzyloxycarbonyl (CBZ), benzyl, and the like) and R 6 is hydrogen] is prepared by reacting a compound of formula 1 with a compound of formula 3 PG-N(R 6 )CR 3 R (CHR) m-1 X (3) where X is an aldehyde, ketone (X = -C(O)R where R is alkyl), carboxy or a reactive carboxy derivative e.g., acid halide. The reaction conditions employed for the preparation of 2 depend on the nature of the X group. If X is an aldehyde or a ketone group, the reaction is carried out under reductive amination reaction conditions i.e., in the presence of a suitable reducing agent (e.g., sodium cyanoborohydride, sodium tiiacetoxyborohydride, and the like) and an organic acid (e.g., glacial acetic acid, trifluoroacetic acid, and the like) at ambient temperature. Suitable solvents for the reaction are halogenated hydrocarbons (e.g., 1,2- dichloroethane, chloroform, and the like). If X is a carboxy group, the reaction is carried out in the presence of a suitable coupling agent (e.g., N,N- dicyclohexylcarbodiimide, l-(3-dimethylaminopropyl)-3-ethylcarbodiimide, and the like) in a suitable organic solvent (e.g., methylene chloride, tetrahydrofuran, and the like) to give an amide intermediate. Reduction of the amide intermediate with a suitable reducing agent (e.g., diborane, lithium aluminum hydride, and the like) in an ethereal organic solvent such as ether or tetrahydrofuran then provides a compound of formula 2. If X is an acid derivative such as an acid chloride, the reaction is carried out in the presence of a suitable base such as triethylamine, pyridine in an organic solvent (e.g., methylene chloride, dichloroethane, N,N-dimethylformamide, and the like) to give an amide intermediate which is reduced to compound 2 as described above. In general, compounds of formula 3 are commercially available or they can be prepared by methods well known in the field of organic chemistry. Some examples of such procedures are illustrated and described in detail below. PG-N(R 6 )CR 3 R 4 C0 2 H PG-N(R 6 ) -1 COR PG-N(R 6 ) (3) (m-l= 1 or 2) (iv) PG-N(R 6 )CR 3 R 4 (CHR) m- ιCOCI (3) (m-l= 1 or 2) (i) An aldehyde of formula 3 (X is a -CHO, and m-1 = 0) is conveniently prepared from the corresponding natural or unnatural α-amino acid of formula 3 where X is a carboxy group and m-1 = 0 by first converting the α-amino acid to the corresponding ester followed by reduction of the ester group to an aldehyde group with a suitable reducing agent such as DIBAL-H ® . An aldehyde of formula 3 where m-1 = 1 or 2 can be prepared, if desired, from an aldehyde or ketone (X = -COR where R is alkyl) of formula 3_ where m-1 = 0 under Wittig reaction conditions. For example, an aldehyde 3 where m-1 = 1 and R is hydrogen or alkyl is prepared by condensing the corresponding aldehyde or ketone of formula 3 where m-1 = 0 with a Wittig reagent derived from chloromethyl methyl ether, followed by acidic hydrolysis of the resulting enol ether intermediate. An aldehyde 3 where m-l= 2 and R are hydrogen or alkyl can be prepared by condensing the corresponding aldehyde or ketone 3 where m-1 = 0 with a Wittig reagent derived from bromoacetate or 2- bromopropionate respectively, followed by sequential reduction of the double bond and the ester group in the resulting α,β-unsaturated ester. The ketone of formula 3 where m-1 = 0 can be prepared from the α-amino acids of formula 3 by converting the α-amino acids 3 to a Weinreb amide, followed by treatment with a Grignard reagent of formula RMgBr where R is an alkyl group. Alternatively, the aldehyde can be prepared by oxidation of the hydroxy group in an α-amino alcohol such as 2- amino- 1 -propanol, and the like. Generally, both natural and unnatural amino acids and their corresponding esters are commercially available from vendors such as Aldrich and Bachem. Examples of unnatural amino acids include, homoserine, homocysteine, N-α- methylarginine, norleucine, N-methylisoleucine, phenylglycine, hydroxyproline, pyroglutamine, ornithine, 2-aminoisobutyric acid, 2-aminobutyric acid, β- cyclohexylalanine, 3-(l-naphthyl)alanine, 3-(2-naphthyl)alanine, citrulline, pipecolinic acid, piperazic acid, 4-chlorophenylalanine, 4-fluorophenylalanine, sarcosine, serine ethyl ester, and alanine methyl ester are commercially available.

Alternatively, they can be prepared from the α,β-unsaturated ester formed in the Wittig reaction, see (i) above, by reduction of the double bond, followed by the hydrolysis of the ester group by methods well known in the art. (iii) Compounds of formula 3 where X is -C(O)R (where R is alkyl) and m-1 = 0, 1 or 2 can be prepared by alkylating the corresponding aldehyde of formula 3 (X is -CHO) with a Grignard reagent, followed by oxidation of the resulting alcohol with a suitable oxidizing agent such as potassium permanganate, and the like. Alternatively, they can be prepared from the corresponding acid of formula 3 as described in (i) above. (iv) Compounds of formula 3 where X is an acid derivative e.g., an acid chloride can be prepared from the corresponding acids of formula 3 (X is -COOH), prepared as described in (iii) above, by chlorinating the carboxy group with a suitable chlorinating agent (e.g., oxalyl chloride, thionyl chloride and the like) in a suitable organic solvent such as methylene chloride and the like. Alternatively, a compound of formula 2 can also be prepared by reacting a compound of formula 1 with an alkylating agent of formula 4 PG-N(R 6 )CR 3 R 4 (CHR) rr 4 where Y is a leaving group under alkylating conditions such as halo (e.g., chloro, bromo or iodo) or sulfonyloxy group (e.g., methylsulfonyloxy or 4-methylphenyl- sulfonyloxy or trifluoromethylsulfonyloxy). The reaction is carried out in the presence of a base such as sodium carbonate, sodium hydride, triethylamine and the like. Suitable solvents are aprotic organic solvents such as tetrahydrofuran, N.N- dimethylformamide, and the like. In general, compounds of formula 4 where Y is a halo or a sulfonyloxy group can be prepared from compounds of formula 3 by reducing an aldehyde, ketone or carboxy group to an alcohol, followed by treatment with a suitable halogenating agent (e.g., thionyl chloride, thionyl bromide, carbon tetrabromide in the presence of triphenylphosphine, and the like) or sulfonylating agent (e.g., methylsulfonyl chloride, para-toluenesulfonyl chloride and triflic anhydride) respectively. Suitable aldehyde, ketone and carboxy group reducing agents include lithium aluminum hydride, borane, and the like. In some instances, a compound of Formula (TJa) can be prepared by reacting a compound of formula 1 with a conjugated nitro-olefin under Michael addition reaction conditions, followed by reduction of the nitro group under standard hydrogenation reaction conditions. Conjugated nitro-olefins are commercially available or can be prepared by known literature procedures e.g., see Corey, E.J. et al, J. Am. Chem. Soc, 100(19), 8294-5, (1978). The N-protected aminoalkyl derivative 2 is converted to a compound of Formula (Ha) by removal of the amino protecting group. The conditions utilized depend on the nature of the protecting group. For example, if the protecting group is the tert-butoxycarbonyl group it is removed under acidic hydrolysis reaction condition whereas if it is the benzyl group it is removed under catalytic hydrogenation reaction conditions. A compound of Formula (TJa) where R 6 is other than hydrogen can be prepared, if desired, by alkylating the corresponding compound of Formula (TJa) where R is hydrogen with an alkylating agent R 6 Y where Y is a leaving group under alkylating conditions, utilizing the reaction conditions described above.

Am. Chem. Soc. 83, 2951 (1961) and removal of the N-protecting group provides a compound of formula 1 where Q is -CO-. Reduction of the olefinic bond in the alkylidene intermediate followed by removal of the N-protecting group provides compounds of formula \ where Q is an alkylene chain.

The α,β-unsaturated ester 7 is converted to the corresponding alcohol derivative 8a (m = 1) by first converting 7 to an aldehyde, followed by treatment with an organometallic reagent such as a Grignard reagent or an organolithium reagent of formula R MgBr or R Li, respectively. The double bond is reduced under hydrogenation reaction conditions and the ester group is reduced to the aldehyde group with a suitable reducing agent such as DLBAL-H 8 .

The compounds of the invention are CCR-3 receptor antagonists and therefore should inhibit recruitment of eosinophil, T cells, basofils and mast cells by chemokines such as RANTES, eotaxin and MCP-3. The quaternary salts of the present invention are, in general, more potent than their corresponding non- quaternized piperidine analogs. Therefore, compounds of this invention and compositions containing them are useful in the treatment of eosiniphil-induced diseases such as asthma, rhinitis, eczema, and parasitic infections in mammals, especially humans. The CCR-3 antagonistic activity of the compounds of this invention may be measured by in vitro assays such as ligand binding and chemotaxis assays as described in more detail in Examples 5, 6 and 7. It can be assayed in vivo by Ovalbumin induced Asthma in Balb/c Mice Model as described in more detail in Example 8. In general, the compounds of this invention will be administered in a therapeutically effective amount by any of the accepted modes of administration for agents that serve similar utilities. The actual amount of the compound of this invention, i.e., the active ingredient, will depend upon numerous factors such as the severity of the disease to be treated, the age and relative health of the subject, the potency of the compound used, the route and form of administration, and other factors. Therapeutically effective amounts of compounds of Formula (I) may range from approximately 0.005-20 mg per kilogram body weight of the recipient per day; preferably about 0.01-10 mg/kg/day. Thus, for administration to a 70 kg person, the dosage range would most preferably be about 0.7 mg to 0.7 g per day. In general, compounds of this invention will be administered as pharmaceutical compositions by any one of the following routes: oral, systemic (e.g., transdermal, intranasal or by suppository), or parenteral (e.g., intramuscular, intravenous or subcutaneous) administration. The preferred manner of administration is oral using a convenient daily dosage regimen which can be adjusted according to the degree of affliction. Compositions can take the form of tablets, pills, capsules, semisolids, powders, sustained release formulations, solutions, suspensions, elixirs, aerosols, or any other appropriate compositions. The choice of formulation depends on various factors such as the mode of drug administration (e.g., for oral administration, formulations in the form of tablets, pills or capsules are preferred) and the bioavailability of the drug substance. For liposomal formulations of the drug for parenteral or oral delivery the drug and the lipids are dissolved in a suitable organic solvent e.g. tert-butanol, cyclohexane (1% ethanol). The solution is lypholized and the lipid mixture is suspended in an aqueous buffer an allowed to form a liposome. If necessary, the liposome size can be reduced by sonification. (see., Frank Szoka, Jr. and Demetrios Papahadjopoulos, "Comparative Properties and Methods of Preparation of Lipid Vesicles (Liposomes)", Ann. Rev. Biophys. Bioeng., 9:467-508 (1980), and D.D. Lasic, "Novel Applications of Liposomes", Trends in Biotech., 16:467- 608, (1998)) Recently, pharmaceutical formulations have been developed especially for drugs that show poor bioavailability based upon the principle that bioavailability can be increased by increasing the surface area i.e., decreasing particle size. For example, U.S. Pat. No. 4,107,288 describes a pharmaceutical formulation having particles in the size range from 10 to 1,000 nm in which the active material is supported on a crosslinked matrix of macromolecules. U.S. Pat. No. 5,145,684 describes the production of a pharmaceutical formulation in which the drug substance is pulverized to nanoparticles (average particle size of 400 nm) in the presence of a surface modifier and then dispersed in a liquid medium to give a pharmaceutical formulation that exhibits remarkably high bioavailability. The compositions are comprised of in general, a compound of Formula (I) in combination with at least one pharmaceutically acceptable excipient. Acceptable excipients are non-toxic, aid administration, and do not adversely affect the therapeutic benefit of the compound of Formula (I). Such excipient may be any solid, liquid, semi-solid or, in the case of an aerosol composition, gaseous excipient that is generally available to one of skill in the art . Solid pharmaceutical excipients include starch, cellulose, talc, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, magnesium stearate, sodium stearate, glycerol monostearate, sodium chloride, dried skim milk and the like. Liquid and semisolid excipients may be selected from glycerol, propylene glycol, water, ethanol and various oils, including those of petroleum, animal, vegetable or synthetic origin, e.g., peanut oil, soybean oil, mineral oil, sesame oil, etc. Preferred liquid carriers, particularly for injectable solutions, include water, saline, aqueous dextrose, and glycols. Compressed gases may be used to disperse a compound of this invention in aerosol form. Inert gases suitable for this purpose are nitrogen, carbon dioxide, etc. Other suitable pharmaceutical excipients and their formulations are described in Remington's Pharmaceutical Sciences, edited by E. W. Martin (Mack Publishing Company, 18th ed., 1990). The level of the compound in a formulation can vary within the full range employed by those skilled in the art. Typically, the formulation will contain, on a weight percent (wt%) basis, from about 0.01-99.99 wt% of a compound of Formula (I) based on the total formulation, with the balance being one or more suitable pharmaceutical excipients. Preferably, the compound is present at a level of about 1-80 wt%. Representative pharmaceutical formulations containing a compound of Formula (I) are described in Example 4.

The CCR-3 LI.2 transfectant cells, designated as 10E6, are grown in culture medium containing RPMI 1640, 10% Hyclone™ fetal calf serum, 5.5% x 10 "5 2-mercaptoethanol and G 418 (0.8 mg/ml). 18-24 hours before the assay, the transfected cells are treated with n-butyric acid at a final concentration of 5 mM/1 x 10 6 cells/ml, isolated and resuspended at 1 x 10 7 cells/ml in assay medium containing equal parts of RPMI 1640 and M199 with 0.5% BSA. Human eotaxin suspended in PBS (Gibco # 14190-029) at 1 mg/ml is added to bottom chamber in a final concentration of 100 nm. Biocoat™ Transwell culture inserts (Costar Corp., Cambridge MA) having 3 micron pore size were inserted into each well and L1.2 cells (1 x 10 6 ) are added to the top chamber in a final volume of lOOμl. Test compounds in DMSO are added both to the top and bottom chambers such that the final DMSO volume was 0.5%. The assay is performed against two sets of controls. Positive control contained cells with no test compound in the top chamber and only eotaxin in the lower chamber. Negative control contained cells with no test compound in the top chamber and neither eotaxin nor test compound in lower chamber. The plate is incubated at 37 °C. After 4 h, the inserts are removed from the chambers and the cells that have migrated to the bottom chamber are counted by pipetting out 500 μl of the cell suspension from the lower chamber to 1.2 ml Cluster tubes (Costar) and counting them on a FACS for 30 sec. Example 9 Inhibition of Eotaxin mediated chemotaxis of human eosinophils— In vitro Assay The ability of compounds of the invention to inhibit eotaxin mediated chemotaxis of human eosinophils can be assessed using a slight modification of procedure described in Carr, M.W. et al., Proc. Natl. Acad. Sci. USA, 91: 3652- 3656 (1994). Experiments are performed using 24 well chemotaxis plates (Collaborative Biomedical Products). Eosinophils are isolated from blood using the procedure described in PCT Application, Publication No. WO 96/22371. The endothelial cells that should be used are the endothelial cell line ECV 304 that can be obtained from European Collection of Animal Cell Cultures (Porton Down, Salisbury, U.K.). Endothelial cells are cultured on 6.5 mm diameter Biocoat® Transwell tissue culture inserts (Costar Corp., Cambridge MA) with a 3.0 μM pore size. Culture media for ECV 304 cells consists of M199, 10% Fetal Calf Serum, L-glutamine and antibiotics. Assay media consists of equal parts RPMI 1640 and M199, with 0.5% BSA. 24 h before the assay 2 x 10 5 ECV 304 cells are plated on each insert of the 24-well chemotaxis plate and incubated at 37 °C. 20 nM of eotaxin diluted in assay medium is added to the bottom chamber. The final volume in bottom chamber was 600 μl. The endothelial coated tissue culture inserts are inserted into each well. 10 6 eosinophil cells suspended in 100 μl assay buffer are added to the top chamber. Test compounds dissolved in DMSO are added to both top and bottom chambers such that the final DMSO volume in each well is 0.5%. The assay is performed against two sets of controls. Positive control contains cells in the top chamber and eotaxin in the lower chamber. Negative control contains cells in the top chamber and only assay buffer in the lower chamber. The plates are incubated at 37 °C in 5% CO 2 /95% air for 1-1.5 h. The cells that have migrated to the bottom chamber are counted using flow cytometry. 500 μl of the cell suspension from the lower chamber is placed in a tube, and relative cell counts is obtained by acquiring events for a set time period of 30 seconds. Example 10 Inhibition of Eosinophil chemotaxis by CCR-3 Antagonist in Ovalbumin sensitized balb/c mice— In vivo Assay The CCR-3 antagonistic activity of the compounds of the invention can be determined by measuring the inhibition of eosinophil accumulation into the BAL fluid of Ovalbumin (OA)-sensitized balb/c mice after antigen challenge by aerosol. Briefly, male balb/c mice weighing 20-25g are sensitized with OA (10 μg in 0.2 ml aluminum hydroxide solution) intraperitoneally on days 1 and 14. After a week, the mice are divided into ten groups. Test compounds or vehicle (positive control group) are administered. After 1 h, the mice are placed in a Plexiglass box and exposed to OA aerosol generated by a PARISTAR™ nebulizer for 20 min. Mice which have not been sensitized or challenged are included as negative control. After 24 or 72 h, the mice are anesthetized (urethane, approx. Ig/kg, i.p.), a tracheal cannula (PE 60 tubing) is inserted and the lungs are lavaged four times with 0.3 ml PBS. The Bal fluid is transferred into plastic tubes and kept on ice. Total leukocytes in a 20 μl aliquot of the BAL fluid is determined by hemocytometer and/or Coulter Counter™. Differential leukocyte counts are made on Cytospin preparations which have been stained with a modified Wright's stain (Diff-Quick™) by light microscopy using standard morphological criteria.
