BACKGROUND OF THE INVENTION Chemoattractant cyto ines or chemokines are a family of proinflammatory mediators that promote recruitment and activation of multiple lineages of leukocytes and lymphocytes . They can be released by many kinds of tissue cells after activation. Continuous release of chemokines at sites of inflammation mediates the ongoing migration of effector cells in chronic inflammation. The chemokines characterized to date are related in primary structure. They share four conserved cysteines, which form disulfide bonds. Based upon this conserved cysteine motif, the family is divided into two main branches, designated as the C-X-C chemokines (α-chemokines) , and the C-C chemokines (β-chemokines) , in which the first two conserved cysteines are separated by an intervening residue, or adjacent respectively (Baggiolini, M. and Dahinden, C. A., Immunology Today, 15:127-133 (1994) ) . The C-X-C chemokines include a number of potent chemoattractants and activators of neutrophils, such as interleukin 8 (IL-8) , PF4 and neutrophil-activating peptide-2 (NAP-2) . The C-C chemokines include RANTES (Regulated on Activation, Normal T Expressed and Secreted) , the macrophage inflammatory proteins l and lβ(MIP-l and MIP-lβ) , eotaxin, and human monocyte chemotactic proteins 1-3 (MCP-1, MCP-2, MCP-3), which have been characterized as chemoattractants and activators of monocytes or lymphocytes but do not appear to be chemoattractants for neutrophils. Chemokines, such as RANTES and MlP-lα, have been implicated in a wide range of human acute and chronic inflammatory diseases including respiratory diseases, such as asthma and allergic disorders. The chemokine receptors are members of a super amily of G protein-coupled receptors (GPCR) which share structural features that reflect a common mechanism of action of signal transduction (Gerard, C. and Gerard, N.P., Annu Rev. Immunol . , 12:775-808 (1994); Gerard, C. and Gerard, N. P., Curr. Opin . Immunol . , 6: 140-145 (1994)) . Conserved features include seven hydrophobic domains spanning the plasma membrane, which are connected by hydrophilic extracellular and intracellular loops. The majority of the primary sequence homology occurs in the hydrophobic transmembrane regions with the hydrophilic regions being more diverse. The first receptor for the C-C chemokines that was cloned and expressed binds the chemokines MlP-lα and RANTES. Accordingly, this MIP-l /RANTES receptor was designated C-C chemokine receptor 1 (also referred to as CCR-1; Neote, K., et al . , Cell , 72:415-425 (1993); Horuk, R. et al . , WO 94/11504, May 26, 1994; Gao, J.-I. et al . , J. Exp. Med . , 177:1421-1427 (1993)). Three receptors have been characterized which bind and/or signal in response to RANTES: CCR3 mediates binding and signaling of chemokines including eotaxin, RANTES, and MCP-3 (Ponath et al., J " . Exp . Med . , 183:2437 (1996)), CCR4 binds chemokines including RANTES, MlP-lα, and MCP-1 (Power, et al., J. Biol . Che . , 270:19495 (1995)), and CCR5 binds chemokines including MlP-lα, RANTES, and MlP-lβ (Samson, et al . , Biochem. 35 : 3362-3367 (1996)). RANTES is a chemotactic chemokine for a variety of cell types, including monocytes, eosinophils, and a subset of T-cells. The responses of these different cells may not all be mediated by the same receptor, and it is possible that the receptors CCR1 , CCR4 and CCR5 will show some selectivity in receptor distribution and function between leukocyte types, as has already been shown for CCR3 (Ponath et al . ) . In particular, the ability of RANTES to induce the directed migration of monocytes and a memory population of circulating T-cells (Schall, T. et al., Nature, 347:669-71 (1990)) suggests this chemokine and its receptor (s) may play a critical role in chronic inflammatory diseases, since these diseases are characterized by destructive infiltrates of T cells and monocytes . Many existing drugs have been developed as antagonists of the receptors for biogenic amines, for example, as antagonists of the dopamine and histamine receptors. No successful antagonists have yet been developed to the receptors for the larger proteins such as chemokines and C5a. Small molecule antagonists of the interaction between C-C chemokine receptors and their ligands, including RANTES and MlP-lα, would provide compounds useful for inhibiting harmful inflammatory processes "triggered" by receptor ligand interaction, as well as valuable tools for the investigation of receptor-ligand interactions. SUMMARY OF THE INVENTION It has now been found that a class of small organic molecules are antagonists of chemokine receptor function and can inhibit leukocyte activation and/or recruitment. An antagonist of chemokine receptor function is a molecule which can inhibit the binding and/or activation of one or more chemokines, including C-C chemokines such as RANTES and/or MlP-lα, to one or more chemokine receptors on leukocytes and/or other cell types. As a consequence, processes and cellular responses mediated by chemokine receptors can be inhibited with these small organic molecules. Based on this discovery, a method of treating a subject with a disease associated with aberrant leukocyte recruitment and/or activation is disclosed as well as a method of treating a disease mediated by chemokine receptor function. The method comprises administering to the subject a therapeutically effective amount of a compound or small organic molecule which is an antagonist of chemokine receptor function. Compounds or small organic molecules which have been identified as antagonists of chemokine receptor function are discussed in detail herein below, and can be used for the manufacture of a medicament for treating or for preventing a disease associated with aberrant leukocyte recruitment and/or activation. The invention also relates to the disclosed compounds and small organic molecules for use in treating or preventing a disease associated with aberrant leukocyte recruitment and/or activation. The invention also includes pharmaceutical compositions comprising one or more of the compounds or small organic molecules which have been identified herein as antagonists of chemokine function and a suitable pharmaceutical carrier.

According to the method, chemokine-mediated chemotaxis and/or activation of pro-inflammatory cells bearing receptors for chemokines can be inhibited.

Cells are harvested by centrifugation, washed twice with PBS (phosphate-buffered saline) , and the cell pellets are frozen at -70 to -85°C. The frozen pellet is thawed in ice-cold lysis buffer consisting of 5 mM HEPES (N-2- hydroxyethylpiperazine-N' -2-ethane-sulfonic acid) pH 7.5, 2 mM EDTA (ethylenediaminetetraacetic acid) , 5 μg/ml each aprotinin, leupeptin, and chymostatin (protease inhibitors) , and 100 μg/ml PMSF (phenyl methane sulfonyl fluoride - also a protease inhibitor) , at a concentration of 1 to 5 x 10 7 cells/ml. This procedure results in cell lysis. The suspension is mixed well to resuspend all of the frozen cell pellet. Nuclei and cell debris are removed by centrifugation of 400 x g for 10 minutes at 4°C. The supernatant is transferred to a fresh tube and the membrane fragments are collected by centrifugation at 25,000 x g for 30 minutes at 4°C. The supernatant is aspirated and the pellet is resuspended in freezing buffer consisting of 10 mM HEPES pH 7.5, 300 mM sucrose, lμg/ml each aprotinin, leupeptin, and chymostatin, and 10 μg/ml PMSF (approximately 0.1 ml per each 10 8 cells). All clumps are resolved using a minihomogenizer, and the total protein concentration is determined using a protein assay kit (Bio-Rad, Hercules, CA, cat #500-0002) . The membrane solution is then aliquoted and frozen at -70 to -85°C until needed. Binding Assays utilize the membranes described above. Membrane protein (2 to 20 μg total membrane protein) is incubated with 0.1 to 0.2 nM 125 I-labeled RANTES or MlP-lα with or without unlabeled competitor (RANTES or MlP-lα) or various concentrations of compounds. The binding reactions are performed in 60 to 100 μl of a binding buffer consisting of 10 mM HEPES pH 7.2 , 1 mM CaCl 2 , 5 mM MgCl 2 , and 0.5% BSA (bovine serum albumin), for 60 min at room temperature. The binding reactions are terminated by harvesting the membranes by rapid filtration through glass fiber filters (GF/B or GF/C, Packard) which are presoaked in 0.3% polyethyleneimine . The filters are rinsed with approximately 600 μl of binding buffer containing 0.5 M NaCl , dried, and the amount of bound radioactivity is determined by scintillation counting in a Topcount beta-plate counter. The activities of test compounds can be reported as IC 50 values or the inhibitor concentration required for 50% inhibition of specific binding in receptor binding assays using 125 I -RANTES or 125 MIP-lα as ligand and THP-1 cell membranes. Specific binding can be defined as the total binding minus the non-specific binding; nonspecific binding can be the amount of cpm still detected in the presence of excess unlabeled RANTES or 125 MIP-lα.
