Field of the Invention \n\n The present invention relates to certain thiazolidinone derivatives useful as modulators of the chemokine receptors, including CCR-1, CCR-2, CCR-2A, CCR-2B, CCR-3, CCR-4, CCR-5, CXCR-1, CXCR-2, CXCR-3, and/or CXCR-4 and to pharmaceutical compositions that include these compounds and a pharmaceutically acceptable carrier. In addition, the present invention is directed to methods for inhibiting HIV infectivity. \n\n 2. Summary of the Related Art \n\n Chemokines mediate a range of proinflammatory effects on leukocytes, such as chemotaxis, degranulation, and intigran activation (Baggiolini et al., Adv. Immunol., 1994;55:97-179; Oppenheim et al., Annu. Rev. Immunol., 1991; 9:617-648; Miller et al., Crit. Rev. Immunol., 1992;12:17-46). These effects are mediated by binding to the seven-transmembrane-spanning G-protein coupled receptors (Baggiolini et al., Adv. Immunol., 1994;55:97-179; Murphy, Annu. Rev. Immunol., 1994;12:593-633; Schall et al., Curr. Opin. Immunol., 1994;6:865-873; Gerard et al., Curr. Opin. Immunol., 1994;6;140-145; Mackay, Curr. Bio., In press). Chemokine receptors also serve as co-receptors for HIV-1 entry into cells. This came from observations that RANTES, MIP-1, and MIP-1 suppressed infection of susceptible cells in vitro by macrophage-tropic primary HIV-1 isolates (Cocchi et al., Science (Wash. D.C.), 1995;270:1811-1815). The chemokine receptor CXCR-4 is found to support infection and cell fusion of CD4 ^{ } cells by laboratory-adapted, T-tropic HIV-1 strains (Feng et al., Science (Wash. D.C.), 1996;272:872-877). CCR-5, a RANTES, MIP-1, and MIP-1 receptor, is subsequently identified as the principle co-receptor for primary macrophage-tropic strains (Choe et al., Cell, 1996;85:1135-1148; Alkhatib et al., Science (Wash. D.C.), 1996;272:1955-1958; Doranz et al., Cell, 1996;85:1149-1158; Deng et al., Nature (Lond.) 1996;381:661-666; Dragic et al., Nature (Lond.), 1996;381:667-3). The importance of CCR-5 for HIV-1 transmission is underscored by the observation that certain individuals who had been repeatedly exposed to HIV-1 but remained uninfected had a defect in CCR-5 expression (Liu et al., Cell, 1996; 86:367-377; Samson et al., Nature (Lond.), 1996;382:722-725; Dean et al., Science (Wash. D.C.), 1996;273:1856-1862; Huang et al., Nature Med., 1996;2:1240-1243). These noninfectable individuals are found to be homozygous for a defective CCR-5 allele that contains an internal 32-base pair deletion (CCR-5 32). The truncated protein encoded by this gene is apparently not expressed at the cell surface. CCR-5 32 homozygous individuals comprise 1% of the Caucasian population and heterozygous individuals comprise 20%. In studies of about 2700 HIV-1 infected individuals, no 32 homozygotes are found. Individuals who are heterozygous for 32 CCR-5 allele have been shown to progress more slowly to AIDS than wild-type homozygous individuals (Samson et al., Nature (Lond.), 1996;382:722-725; Dean et al., Science (Wash. D.C.), 1996;273:1856-1862; Huang et al., Nature Med., 1996;2:1240-1243). Thus, the identity of CCR-5 as the principle co-receptor for primary HIV isolates provides an opportunity to understand disease pathogenesis, and more importantly to identify a new avenue for the treatment of HIV-1 infection. \n\n The instant invention is a series of finctionalized heterocycles that block the CD-4/GP-120 interaction with CCR-5 receptor, and thus can be useful in the treatment of HIV infection manifested in AIDS. \n\n SUMMARY OF THE INVENTION \n\n The compounds of the invention are useful in a method of modulating chemokine receptor activity in a patient in need of such modulation, the method comprising the administration of an effective amount of the compound to a subject, preferably mammalian, in need thereof. \n\n The present invention is directed to the use of thiazolidinone derivatives as modulators of chemokine receptor activity. In particular, these compounds are useful as modulators of chemokine receptors, including CCR-1, CCR-2, CCR-2A, CCR-2B, CCR-3, CCR-4, CCR-5, CXCR-3, CXCR1, CXCR2, and/or CXCR-4.

Also contemplated are salts of amino acids such as arginate and the like and gluconate, galacturonate (see, for example, Berge S. M. et al., Pharmaceutical Salts, J. of Pharma. Sci., 1977;66:1). \n\n The acid addition salts of said basic compounds are prepared by contacting the free base form with a sufficient amount of the desired acid to produce the salt in the conventional manner. The free base form may be regenerated by contacting the salt form with a base and isolating the free base in the conventional manner. The free base forms differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free base for purposes of the present invention. \n\n Pharmaceutically acceptable base addition salts are formed with metals or amines, such as alkali and alkaline earth metals or organic amines.

The free acid form may be regenerated by contacting the salt form with an acid and isolating the free acid in the conventional manner. The free acid forms differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free acid for purposes of the present invention. \n\n Certain of the compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms, including hydrated forms, are equivalent to unsolvated forms and are intended to be encompassed within the scope of the present invention. \n\n Certain of the compounds of the present invention possess one or more chiral centers and each center may exist in the R or S configuration. The present invention includes all diastereomeric, enantiomeric, and epimeric forms as well as the appropriate mixtures thereof. Additionally, the compounds of the present invention may exist as geometric isomers. The present invention includes all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof. \n\n Representative compounds of the invention are shown below in Table 1, below. Each compound is assigned a number, which number will be referred to below in the working examples and in subsequent tables. \n\n\n TABLE 1 \n\n\n 1 \n\n\n 2 \n\n\n 3 \n\n\n 4 \n\n\n 5 \n\n\n 6 \n\n\n 7 \n\n\n 8 \n\n\n 9 \n\n\n 10 \n\n\n 11 \n\n\n 12 \n\n\n 13 \n\n\n 14 \n\n\n 15 \n\n\n 16 \n\n\n 17 \n\n\n 18 \n\n\n 19 \n\n\n 20 \n\n\n 21 \n\n\n 22 \n\n\n 23 \n\n\n Representative compounds of the present invention, which are encompassed by Formula I include, but are not limited to, the compounds in Table 1 and their pharmaceutically acceptable acid or base addition salts, or amide or prodrugs thereof, as well as solvates and hydrates thereof. \n\n The compounds of the present invention can be prepared and administered in a wide variety of oral and parenteral dosage forms. Thus, the compounds of the present invention can be administered by injection, that is, intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally. Also, the compounds of the present invention can be administered by inhalation, for example, intranasally. Additionally, the compounds of the present invention can be administered transdermally. It will be obvious to those skilled in the art that the following dosage forms may comprise as the active component, either a compound of Formula I or a corresponding pharmaceutically acceptable salt of a compound of Formula 1. \n\n For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material. \n\n In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component. \n\n In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. \n\n The powders and tablets preferably contain from five or ten to about seventy percent of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term preparation is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component, with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration. \n\n For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify. \n\n Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution. \n\n Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizing, and thickening agents as desired. \n\n Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents. \n\n Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like. \n\n The pharmaceutical preparation is preferably in unit dosage form. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form. \n\n The quantity of active component in a unit dose preparation may be varied or adjusted from 1 mg to 1000 mg, preferably 10 mg to 100 mg according to the particular application and the potency of the active component. The composition can, if desired, also contain other compatible therapeutic agents. \n\n In therapeutic use as agents for the treatment of HIV infection, the compounds utilized in the pharmaceutical method of this invention can be administered at the initial dosage of about 1 mg to about 100 mg per kilogram daily. A daily dose range of about 25 mg to about 75 mg per kilogram is preferred. The dosages, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the compound being employed. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under the circumstance is reached. For convenience, the total daily dosage may be divided and administered in portions during the day if desired. \n\n The compounds of Formula I are valuable antagonists of the CCR-5 chemokine receptor. As such, these compounds are useful scientific research tools for studying the role of CCR-5 in various biological processes in vitro. Compounds which are antagonists of the CCR-5 chemokine receptor are expected to have efficacy in inhibiting HIV infection and are thus useful in the treatment of AIDS. The compounds of the present invention are evaluated in a CCR-5 receptor binding assay (see below). \n\n The examples presented below are intended to illustrate particular embodiments of the invention, and are not intended to limit the scope of the specification or the claims in any way. \n\n An illustration of the preparation of compounds of the present invention is shown in Schemes 1-2. R ^{ 1 } , R ^{ 11 } , R ^{ 8 } , and R ^{ 9 } are as defined above for Formula I. \n\n Armed with the disclosure provided herein (particularly the schemes and the synthetic examples that follow) and knowledge common to all who practice in the field, those of ordinary skill in the art will be able to make and use the entire scope of compounds disclosed herein. \n\n The invention compounds can be prepared by any of several synthetic methods, utilizing standard methodologies well-known to those skilled in organic chemistry. Preferred methods of synthesis of the final target compounds is shown in Schemes 1-2. \n\n In Scheme 1, a Schiff base is first prepared from the corresponding aryl aldehyde and a haloalkylamine, for example, 3-chloropropylamine. The imine intermediate (Schiff base) is then reacted with a cyclizing agent such as mercaptoacetic acid to afford a substituted 4-thiazolidinone. The chloride is displaced with an amine in the presence of base, preferably a tertiary base, to afford the 3-aminosubstitutedpropyl-4-thiazolidinone. This thiazolidinone is reacted with an aryl aldehyde such as benzaldehyde in the presence of a strong base, as, for example, potassium t-butoxide, to yield the 5-methylene thiazolidinone of the invention. \n\n Alternatively, the synthetic sequence depicted in Scheme 2 can be used to prepare the compounds of the invention. For example, a benzaldehyde is reacted with a 3-aminosubstituted propylamine to afford a Schiff base. As in Scheme 1, the imine Schiff base intermediate is next reacted with mercaptoacetic acid at reflux to afford the corresponding 4-thiazolidinone. The 4-thiazolidinone is subsequently reacted with another benzaldehyde in the presence of a strong base, as, for example, potassium t-butoxide to yield the final product. The route shown in Scheme 2 is especially suited for preparing invention compounds having a second substituent at the 2-position of the 4-thiazolidinone. \n\n The present invention is further directed to combinations of the present compounds with one or more agents useful in the prevention or treatment of AIDS. For example, the compounds of this invention may be effectively administered, whether at periods of pre-exposure and/or postexposure, in combination with effective amounts of the anti-HIV compounds, immunomodulators, anti-infectives, or prophactic or therapeutic vaccines known to those of ordinary skill in the art. Examples of such compounds are found in Table 2, below. \n\n\n TABLE 2 \n\n Drug Name Manufacturer Indication \n\n\n ANTIVIRALS \n 097 Hoechst/Bayer HW infection, AIDS, ARC \n (non-nucleoside reverse \n transcriptase (RT) inhibitor) \n GW141 Glaxo Wellcome HIV infection, AIDS, ARC \n W94/VX473 (protease inhibitor) \n Amprenavir \n GW1592U89 Glaxo Wellcome HW infection, AIDS, ARC \n Abacavir (RT inhibitor) \n Acemannan Carrington Labs ARC \n (Irving, Tx) \n Acyclovir Burroughs Wellcome HIV infection, AIDS, \n ARC, in Combination \n with AZT \n AD-439 Tanox Biosystems HIV infection, AIDS, ARC \n AD-519 Tanox Biosystems HIV infection, AIDS, ARC \n Adefovir dipivoxil Gilead Sciences HIV infection \n AL-721 Ethigen ARC, PGL HIV positive, \n (Los Angeles, CA) AIDS \n Alpha Interferon Glaxo Wellcome Kaposi's sarcoma, HIV in \n combination \n Alferon Interferon Inteferon Sciences Kaposi's sarcoma, HIV in \n combination \n Ansamycin Adria Laboratories ARC \n LM 427 (Dublin, OH) \n Erbamont \n (Stamford, CT) \n Antibody which Advanced Biotherapy AIDS, ARC \n neutralizes pH Concepts \n labile alpha aberrant (Rockville, MD) \n Interferon \n AR177 Aronex Pharm HIV infections, AIDS, \n ARC \n beta-fluoro-ddA Nat'l Cancer Institute AIDS-associated diseases \n BMS-232623 Bristol-Myers HIV infection, AIDS, ARC \n (CGP-73547) Squibb/Novartis (protease inhibitor) \n BMS-234475 Bristol-Myers HIV infection, AIDS, ARC \n (CGP-61755) Squibb/Novartis (protease inhibitor) \n (-)6-Chloro-4(S)- Merck HIV infection, AIDS, ARC \n cyclopropylethynyl- (non-nucleoside reverse \n 4(S)-trifluoro- transcriptase inhibitor) \n methyl-1,4-dihydro- \n 2H-3,1-benzoxazin- \n 2-one \n CI-1012 Warner-Lambert HIV-1 infection \n Cidofovir Gilead Science CMV retinitis, herpes, \n papillomavirus \n Combivir AZT Glaxo Wellcome HIV infection, AIDS, ARC \n 3TC \n Curdlan sulfate AJI Pharma USA HIV infection \n Cytomegalovirus MedImmune CMV retinitis \n immune globin \n Cytovene Syntex/Roche Sight threatening CMV, \n Ganciclovir peripheral CMV, retinitis \n Delaviridine Pharmacia-Upjohn HIV infection, AIDS, ARC \n (RT inhibitor) \n Dextran Sulfate Ueno Fine Chem.

Likewise, solutions of, 4-N,N-dimethylamino-piperidine (ii), 1-(2-pyridyl)piperazine (iii), piperidine (iv), 4-piperidino-piperidine (v), morpholine (vi), 1-(2-pyrimidyl)piperazine (vii), 1-cyclohexylpiperazine (viii), phenyl-1,3,8-triazaspiro-4,5decan-4-one (ix), and 3-(tert-butoxycarbonylamino) pyrrolidine (x) are added to rows ii, iii, iv, v, vi, vii, viii, ix, and x, respectively. Diisopropylethyl amine (2.64 mL of a 0.5 M solution, 1.32 mmol) is then added to every well via the liquid handling robot. The 40 vessels are capped and heated overnight at 73 C. with agitation. The solutions are cooled and treated with polystyrene supported isocyanate resin (0.3 g, 1.7 mmol/g, 0.5 mmol). The heterogeneous mixtures are agitated 4 hours at room temperature and concentrated with the GeneVac. The contents of each vial is dissolved in CHCl _{ 3 } and placed on top of a Varian Chem Elut hydromatrix column (CE1003) which has been pre-washed with 2 M HCl. The product is eluted from each column with CHCl _{ 3 } (5 mL). The eluents are treated with MgSO _{ 4 } , filtered, and concentrated into 2 dram pre-weighed vials with a GeneVac solvent concentrator. \n\n The individual samples are dissolved in methanol (4.5 mL) and split into four new plates by the transfer of 1 mL aliquots. This creates four identical 410 arrays. \n\n Array 1 is diluted with toluene (2 mL), and each well is treated with 3-fluorobenzaldehyde (I) (2 mL of a 0.3 M solution, 0.6 mmol), followed by the addition of 3 molecular sieves (10 pellets). Potassium tert-butoxide (0.9 mL of a 1 M solution in THF, 0.9 mmol) is then added, and the mixtures are heated to 65 C. for 5 hours, cooled to room temperature, and treated with polyamine resin (0.2 g) (Booth and Hodges, J. Am. Chem. Soc., 1997; 119:4882) and basic alumina (activity grade I, 0.3 g), and agitated overnight at room temperature. Each individual reaction is placed on top of an acidic ion exchange column (Baker 7090-07) previously treated with a water/methanol solution. The columns are eluted with methanol (5 mL) to remove impurities followed by ammonia in methanol (5 mL of a 2 M solution, 10 mmol) to elute the products. The individual methanolic ammonia fractions are placed into pre-weighed 2 dram vials and concentrated on the GeneVac. \n\n In a likewise fashion array 2 is reacted with 3-trifluoromethyl-benzaldehyde (II), array 3 with benzaldehyde (III), and array 4 with 3-chlorobenzaldehyde (IV). The products are purified in the manner of array 1. \n\n Results of Array Synthesis \n\n Results of the combinatorial synthesis of new Thiazolidinone compounds are shown in Table 4, below. \n\n\n TABLE 4 \n\n Reagent 1 HPLC \n Cmpd (Thiazolidin- Reagent 2 Reagent 3 RT \n IUPAC Name 4-one) (amine) (aldehyde) LC-MS (min) \n\n 25 5-(3-Fluoro-benzylidene)- A 4 I 479 3.0 \n 3-(3-piperidin-1-yl-propyl)- \n 2-(3-trifluoromethyl-phenyl)- \n thiazolidin-4-one \n 26 5-(3-Fluoro-benzylidene)-2- B 3 I 507 2.3 \n (3-fluoro-phenyl)-3-3-(4- \n pyridin-2-yl-piperazin-1-yl)- \n propyl-thiazolidin-4-one \n 27 3-3-(4-Cyclohexyl-piperazin- B 8 I 512 2.5 \n 1-yl)-propyl-5-(3-fluoro- \n benzylidene)-2-(3-fluoro- \n phenyl)-thiazolidin-4-one \n 28 2-(3-Chloro-phenyl)-5-(3- D 3 I 523 2.4 \n fluoro-benzylidene)-3-3-(4- \n pyridin-2-yl-piperazin-1-yl)- \n propy1-thiazolidin-4-one \n 29 2-(3-Chloro-phenyl)-5-(3- D 7 I 524 3.0 \n fluoro-benzylidene)-3-3-(4- \n pyrimidin-2-yl-piperazin- \n 1-yl)-propyl-thiazolidin-4-one \n 30 2-(3-Chloro-phenyl)-3-3-(4- D 3 II 573 2.7 \n pyridin-2-yl-piperazin-1-yl)- \n propyl-5-(3-trifluoromethyl- \n benzylidene)-thiazolidin-4-one \n 31 2-(3-Chloro-phenyl)-3-(3- D 4 II 495 3.3 \n piperidin-1-yl-propyl)-5-(3- \n trifluoromethyl-benzylidene)- \n thiazolidin-4-one \n 32 2-(3-Chloro-phenyl)-3-3-4- D 7 II 574 3.3 \n pyrimidin-2-yl-piperazin- \n 1-yl)-propyl-5-(3- \n trifluoromethyl-benzylidene)- \n thiazolidin-4-one \n 33 5-Benzylidene-3-3-(4- A 3 III 539 2.4 \n pyridin-2-yl-piperazin-1-yl)- \n propyl-2-(3-trifluoromethyl- \n phenyl)-thiazolidin-4-one \n 34 5-Benzylidene- A 7 III 540 3.0 \n 3-3-(4-pyrimidin-2-yl- \n piperazin-1-yl)-propyl- \n 2-(3-trifluoromethyl-phenyl)- \n thiazolidin-4-one \n 35 5-Benzylidene-2-(3-fluoro- B 3 III 489 2.2 \n phenyl)-3-3-(4-pyridin-2-yl- \n piperazin-1-yl)-propyl- \n thiazolidin-4-one \n 36 5-Benzylidene-2-(3-fluoro- B 4 III 411 2.8 \n phenyl)-3-(3-piperidin-1-yl- \n propyl)-thiazolidin-4-one \n 37 5-Benzylidene-3-(3- B 5 III 494 2.1 \n 1,4bipiperidinyl-1-yl- \n propyl)-2-(3-fluoro-phenyl)- \n thiazolidin-4-one \n 38 5-Benzylidene-3-3-(4- B 8 III 494 2.4 \n cyclohexyl-piperazin-1-yl)- \n propyl-2-(3-fluoro-phenyl)- \n thiazolidin-4-one \n 39 5-Benzylidene-2-3-nitro- C 7 III 517 5.2 \n phenyl)-3-3-(4-pyrimidin- \n 2-yl-piperazin-1-yl)-propyl- \n thiazolidin-4-one \n 40 5-Benzylidene-2-(3-chloro- D 3 III 505 2.4 \n phenyl)-3-3-(4-pyridin-2-yl- \n piperazin-1-yl)-propyl- \n thiazolidin-4-one \n 41 5-Benzylidene-3-(3- D 5 III 510 2.3 \n 1,4bipiperidinyl-1-yl- \n propyl)-2-(3-chloro-phenyl)- \n thiazolidin-4-one \n 42 5-Benzylidene-2-(3-chloro- D 6 III 429 2.7 \n phenyl)-3-(3-morpholin-4-yl- \n propyl)-thiazolidin-4-one \n 43 5-Benzylidene-2-(3-chloro- D 7 III 506 2.9 \n phenyl)-3-3-(4-pyrimidin- \n 2-yl-piperazin-1-yl)-propyl- \n thiazolidin-4-one \n 44 5-Benzylidene-2-(3-chloro- D 8 III 510 2.6 \n phenyl)-3-3-(4-cyclohexyl- \n piperazin-1-yl)-propyl- \n thiazolidin-4-one \n 45 5-(3-Chloro-benzylidene)- A 7 IV 574 3.3 \n 3-3-(4-pyrimidin-2-yl- \n piperazin-1-yl)-propyl- \n 2-(3-trifluoromethyl-phenyl)- \n thiazolidin-4-one \n 46 5-(3-Chloro-benzylidene)-3- A 8 IV 578 2.9 \n 3-(4-cyclohexyl-piperazin- \n 1-yl)-propyl-2-(3- \n rifluoromethyl-phenyl)- \n thiazolidin-4-one \n 47 5-(3-Chloro-benzylidene)- B 3 IV 523 2.5 \n 2-(3-fluoro-phenyl)-3-3-(4- \n pyridin-2-yl-piperazin-1-yl)- \n propyl-thiazolidin-4-ne \n 48 5-(3-Chloro-benzylidene)- B 7 IV 524 3.0 \n 2-(3-fluoro-phenyl)-3-3-(4- \n pyrimidin-2-yl-piperazin-1- \n yl)-propyl-thiazolidin-4-one \n 49 5-(3-Chloro-henzylidene)- B 8 IV 528 2.7 \n 3-3-(4-cyclohexyl-piperazin- \n 1-yl)-propyl-2-(3-fluoro- \n phenyl)-thiazolidin-4-one \n 50 5-(3-Chloro-benzylidene)- D 3 IV 539 2.6 \n 2-(3-chloro-phenyl)-3-3- \n (4-pyridin-2-yl-piperazin- \n 1-yl)-propyl-thiazolidin- \n 4-one \n 51 5-(3-Chloro-benzylidene)- D 7 IV 540 3.2 \n 2-(3-chloro-phenyl)- \n 3-3-(4-pyrimidin-2-yl- \n piperazin-1-yl)-propyl- \n thiazolidin-4-one \n 52 5-(3-Chloro-benzylidene)- D 8 IV 544 2.8 \n 2-(3-chloro-phenyl)-3-3-(4- \n cyclohexyl-piperazin-1-yl)- \n propyl-thiazolidin-4-one \n\n\n Example 5 \n\n CCR-5 Receptor Binding Assay \n\n The ^{ 125 } I-gp120/sCD4/CCR-5 binding assay is carried out similarly as described in Wu et al., Nature, 1996;384:179-183. Briefly, the envelope gp120 protein derived from HIV-1 JR-FL (Trkola et al., Nature, 1996;384:184-186), a M-tropic strain, is iodinated using solid phase lactoperoxidase to a specific activity of 20 Ci/g. For each binding reaction (in a final volume of 100 L binding buffer 50 mM HEPES, pH 7.5, 1 mM CaCl _{ 2 } , 5 mM MgCl _{ 2 } , and 0.5% BSA), 25 L (2.5 g) of membranes prepared from CCR-5/L 1.2 cells are mixed with 25 L (3 nM) sCD4, followed by 25 L (0.1 nM) radiolabeled gp120 in the presence or absence of 25 L compound dissolved in DMSO (final concentration of DMSO 0.5%). The reactions are incubated at room temperature for 45 to 60 minutes and stopped by transferring the mixture to GFB filter plates, which are then washed 3 to 4 times with binding buffer containing 0.5 M NaCl. The plates are dried and MicroScint scintillation fluid is added before counting. \n\n The results of the CCR-5 assay are shown in Table 5, below. For Compounds 1-24, results of the assay are expressed as IC _{ 50 } (M), while for Compounds 25-52, results are expressed as % Inhibition at 10 M. As seen in Table 5, the compounds of the invention, represented by Formula I, block the sCD-4/GP-120 binding to CCR-5 receptor with affinity less than or equal to 20 M. \n\n\n TABLE 5 \n\n Compound \n\n\n IC _{ 50 } (M) \n 1 10.8 \n 2 0.25 \n 3 0.28 \n 4 0.20 \n 5 0.71 \n 6 1.26 \n 7 0.14 \n 8 0.78 \n 9 0.39 \n 10 1.04 \n 11 0.98 \n 12 6.64 \n 13 2.82 \n 14 0.46 \n 15 12.67 \n 16 3.81 \n 17 0.071 \n 18 4.12 \n 19 0.28 \n 20 0.17 \n 21 1.4 \n 22 0.4 \n 23 1.99 \n 24 3.10 \n % Inhib. \n 10 M \n 25 50.7 \n 26 75.3 \n 27 57.6 \n 28 78.8 \n 29 86.8 \n 30 61.7 \n 31 54.4 \n 32 81.8 \n 33 62.0 \n 34 79.2 \n 35 76.2 \n 36 63.3 \n 37 56.6 \n 38 54.4 \n 39 70.1 \n 40 84.3 \n 41 62.4 \n 42 64.7 \n 43 95.0 \n 44 54.5 \n 45 57.7 \n 46 51.1 \n 47 75.6 \n 48 84.7 \n 49 54.0 \n 50 77.8 \n 51 84.0 \n 52 43.7 \n\n\n As noted above, the invention compounds are potent modulators of chemokine receptor activity, and as such are useful medical agents for preventing and treating inflammatory disease and viral infections such as HIV.
