Description: IL-8 RECEPTOR ANTAGONISTS FIELD OF THE INVENTION This invention relates to novel guanidine substituted compounds, pharmaceutical compositions, processes for their preparation, and use thereof in treating IL-8, GROα, GROβ, GROγ and NAP-2 mediated diseases BACKGROUND OF THE INVENTION Many different names have been applied to Interleukιn-8 (IL-8), such as neutrophil attractant/activation protein- 1 (NAP-1 ), monocyte derived neutrophil chemotactic factor (MDNCF), neutrophil activating factor (NAF), and T-cell lymphocyte chemotactic factor Interleukιn-8 is a chemoattractant for neutrophils, basophils, and a subset of T-cells It is produced by a majority of nucleated cells including macrophages, fibroblasts, endothelial and epithelial cells exposed to TNF, IL-lα, IL-lβ or LPS, and by neutrophils themselves when exposed to LPS or chemotactic factors such as FMLP.

IL-8, GROα, GROβ, GROγ and NAP-2 stimulate a number of functions in vitro They have all been shown to have chemoattractant properties for neutrophils, while IL-8 and GROa have demonstrated T-lymphocytes, and basophiles chemotactic activity In addition IL-8 can induce histamine release from basophils from both normal and atopic individuals GRO-α and IL-8 can in addition, induce lysozomal enzyme release and respiratory burst from neutrophils IL-8 has also been shown to increase the surface expression of Mac- 1 (CD1 lb/CD 18) on neutrophils without de novo protein synthesis This may contribute to increased adhesion of the neutrophils to vascular endothelial cells Many known diseases are characterized by massive neutrophil infiltration As IL-8. Groα, GROβ, GROγ and NAP-2 promote the accumulation and activation of neutrophils, these chemokmes have been implicated in a wide range of acute and chronic inflammatory disorders including psoriasis and rheumatoid arthritis.

Am Rev. Respir Pis 146. 427 (1992). Donnely et al , Lancet 341. 643 (1993) In addition the ELR chemokmes (those containing the amino acids ELR motif just prior to the CXC motif) have also been implicated in angiostasis Stπeter et al, Science 258, 1798 (1992) In vitro, IL-8, GROα, GROβ, GROγ and NAP-2 induce neutrophil shape change, chemotaxis, granule release, and respiratory burst, by binding to and activating receptors of the seven-transmembrane, G-protein-hnked family, in particular by binding to IL-8 receptors, most notably the B-receptor Thomas et al , J Biol Chem 266. 14839 ( 1991 ). and Holmes et al . Science 253. 1278 ( 1991 ) The development of non-peptide small molecule antagonists for members of this receptor family has precedent For a review see R Freidinger in Progress in Drug Research. Vol 40, pp 33-98, Birkhauser Verlag, Basel 1993 Hence, the IL-8 receptor represents a promising target for the development of novel anti-inflammatory agents Two high affinity human IL-8 receptors (77% homology) have been characterized. IL-8Ra. which binds only IL-8 with high affinity, and IL-8Rb, which has high affinity for IL-8 as well as for GROα, GROβ, GROγ and NAP-2 See Holmes et al , supra; Murphy et al., Science 253. 1280 ( 1991), Lee et al , J Biol Chem 267. 16283 (1992), LaRosa et al , J Biol Chem 267. 25402 ( 1992), and Gavle et al . J Biol Chem 268. 7283 ( 1993) There remains a need for treatment, in this field, tor compounds which are capable of binding to the IL-8 a or b receptor. Therefore, conditions associated with an increase in IL-8 production (which is responsible for chemotaxis of neutrophil and T-cells subsets into the inflammatory site) would benefit by compounds which are inhibitors of IL-8 receptor binding SUMMARY OF THE INVENTION This invention provides for a method of treating a chemokine mediated disease, wherein the chemokine is one which binds to an IL-8 a or b receptor and which method comprises administering an effective amount of a compound of Formula (I) or a pharmaceutically acceptable salt thereof.

IL-1 is a ma|or component, and whose production or action, is exacerbated or secreted in response to IL-8, would therefore be considered a disease stated mediated by IL-8. As used herein, the term "cytokine" refers to any secreted polypeptide that affects the functions of cells and is a molecule which modulates interactions between cells in the immune, inflammatory or hematopoietic response. A cytokine includes, but is not limited to, monokines and lymphokines, regardless of which cells produce them. For instance, a monokine is generally referred to as being produced and secreted by a mononuclear cell, such as a macrophage and/or monocyte. Many other cells however also produce monokines, such as natural killer cells, fibroblasts, basophils, neutrophils, endothelial cells, brain astrocytes, bone marrow stromal cells, epideral keratinocytes and B-lymphocytes. Lymphokines are generally referred to as being produced by lymphocyte cells. Examples of cytokines include, but are not limited to, Interleukin- 1 (IL- 1 ), Interleukιn-6 (IL-6), Interleukιn-8 (IL-8), Tumor Necrosis Factor-alpha (TNF-α) and Tumor Necrosis Factor beta (TNF-β) As used herein, the term "chemokine" refers to any secreted polypeptide that affects the functions of cells and is a molecule which modulates interactions between cells in the immune, inflammatory or hematopoietic response, similar to the term "cytokine" above. A chemokine is primarily secreted through cell transmembranes and causes chemotaxis and activation of specific white blood cells and leukocytes, neutrophils, monocytes, macrophages, T-cells, B-cells, endothelial cells and smooth muscle cells. Examples of chemokmes include, but are not limited to, IL-8, GRO- α, GRO-β, GROγ, ENA-78, NAP-2, IP- 10, MlP- l a, MlP-b, PF4, and MCP 1 , 2, and 3 In order to use a compound of Formula (I) or a pharmaceutically acceptable salt thereof in therapy, it will normally be formulated into a pharmaceutical composition in accordance with standard pharmaceutical practice.

After 1 hour at room temperature the plate is harvested using a Tomtec 96-well harvester onto a glass fiber filtermat blocked with 1 % polyethylenimine/0.5% BSA and washed 3 times with 25 mM NaCl, 10 mM TrisHCl. 1 mM MgSOd, 0.5 mM EDTA, 0.03 % CHAPS. pH 7.4. The filter is then dried and counted on the Betaplate liquid scintillation counter. The recombinant IL- 8 Rα, or Type I, receptor is also referred to herein as the non-permissive receptor and the recombinant IL-8 Rβ, or Type II, receptor is referred to as the permissive receptor. Chemotaxis Assay : The in vitro inhibitory properties of these compounds are determined in the neutrophil chemotaxis assay as described in Current Protocols in Immunology, vol I, Suppl 1, Unit 6.12.3., whose disclosure is incorporated herein by reference in its entirety. Neutrophils where isolated from human blood as described in Current Protocols in Immunology Vol I, Suppl 1 Unit 7.23.1 , whose disclosure is incorporated herein by reference in its entirety. The chemoattractants IL-8, GRO-α, GRO-β, GRO-γ and NAP-2 are placed in the bottom chamber of a 48 multiwell chamber (Neuro Probe, Cabin John, MD) at a concentration between 0.1 and 100 nM. The two chambers are separated by a 5um polycarbonate filter. When compounds of this invention are tested, they are mixed with the cells (0.001 - 1000 nM) just prior to the addition of the cells to the upper chamber. Incubation is allowed to proceed for between about 45 and 90 min at about 37°C in a humidified incubator with 5% CO2- At the end of the incubation period, the polycarbonate membrane is removed and the top side washed, the membrane then stained using the Diff Quick staining protocol (Baxter Products, McGaw Park, IL, USA). Cells which have chemotaxed to the chemokine are visually counted using a microscope. Generally, four fields are counted for each sample, these numbers are averaged to give the average number of cells which had migrated. Each sample is tested in triplicate and each compound repeated at least tour times To certain cells (positive control cells) no compound is added, these cells represent the maximum chemotactic response of the cells 5 In the case where a negative control (unstimulated) is desired, no chemokine is added to the bottom chamber. The difference between the positive control and the negative control represents the chemotactic activity of the cells Elastase Release Assay 10 The compounds of this invention are tested for their ability to prevent Elastase release from human neutrophils. Neutrophils are isolated from human blood as described in Current Protocols in Immunology Vol I, Suppl 1 Unit 7 23 1 PMNs 0 88 x IO 6 cells suspended in Ringer's Solution (NaCl 1 18. CI 4 56, NaHCO3 25. KH2PO4 1 03, Glucose 1 1 1 , HEPES 5 mM. pH 7 4) are placed in each well of a 96 well plate in i s a volume of 50 ul To this plate is added the test compound (0 001 - 1000 nM) in a volume of 50 ul, Cytochalasin B in a volume of 50 ul (20ug/ml) and Ringers buffer in a volume of 50 ul These cells are allowed to warm (37 °C, 5% CO2, 95% RH) for 5 min before IL-8, GROα, GROβ, GROγ or NAP-2 at a final concentration of 0.01 - 1000 nM was added The reaction is allowed to proceed for 45 min before the 96 well plate is 0 centrifuged (800 xg 5 min) and 100 ul of the supernatant removed This suppernatant is added to a second 96 well plate followed by an artificial elastase substrate (MeOSuc- Ala-Ala-Pro-Val-AMC, Nova Biochem, La Jolla, CA) to a final concentration ot 6 ug/ml dissolved in phosphate buffered saline. Immediately, the plate is placed in a fluorescent 96 well plate reader (Cytofluor 2350, Milhpore. Bedford, MA) and data 5 collected at 3 min intervals according to the method of Nakajima et al J Biol Chem 254 4027 ( 1979) The amount of Elastase released from the PMNs is calculated by measuring the rate of MeOSuc-Ala-Ala-Pro-Val-AMC degradation TNF-α in Traumatic Brain Injury Assay 0 The present assay provides for examination of the expression of tumor necrosis factor mRNA in specfic brain regions which follow experimentally induced lateral fluid- percussion traumatic brain injury (TBI) in rats Adult Sprague-Dawley rats (n=42) were anesthetized with sodium pentobarbital (60 mg/kg, l p.) and subjected to lateral fluid- percussion brain injury of moderate severity (2.4 atm ) centered over the left 5 temporaparietal cortex (n= 18), or "sham" treatment (anesthesia and surgery without injury, n=18) Animals are sacrificed by decapitation at 1 , 6 and 24 hr. post injury, brains removed, and tissue samples ot left (injured) parietal cortex (LC), corresponding area in the contralateral right cortex (RC), cortex adjacent to injured parietal cortex (LA), corresponding adjacent area in the right cortex (RA), left hippocampus (LH) and right hippocampus (RH) are prepared Total RNA was isolated and Northern blot hybridization is performed and quantitated relative to an TNF-α positive control RNA (macrophage = 100%) A marked increase of TNF- α mRNA expression is observed in LH ( 104±i 7% of positive control, p < 0 05 compared with sham), LC ( 105±21 %, p< 005) and LA (69±8%, p < 0 01) m the traumatized hemisphere 1 hr following injury An increased TNF- α mRNA expression is also observed in LH (46±8%, p < 005), LC (30±3%, p < 0 01) and LA (32±3%, p < 0 01) at 6 hr which resolves by 24 hr. following injury In the contralateral hemisphere, expression of TNF- α mRNA is increased in RH (46±2%, p < 0 01), RC (4±3%) and RA (22±8%) at 1 hr and in RH (28±1 1 %), RC (7±5%) and RA (26±6%, p < 0 05) at 6 hr but not at 24 hr following injury In sham (surgery without injury) or naive animals, no consistent changes in expression of TNF- α mRNA are observed in any ot the 6 brain areas in either hemisphere at any times These results indicate that following parasagittal fluid-percussion brain injury, the temporal expression of TNF-α mRNA is altered in specific brain regions, including those of the non- traumatized hemisphere Since TNF- α is able to induce nerve growth factor (NGF) and stimulate the release of other cytokines from activated astrocytes, this post-traumatic alteration in gene expression of TNF-α plays an important role in both the acute and regenerative response to CNS trauma CNS Iniurv model for IL-β mRNA This assay characterizes the regional expression of interleukin- I B (IL- lβ) mRNA in specific brain regions following experimental lateral fluid-percussion traumatic brain injury (TBI) in rats Adult Sprague-Dawley rats (n=42) are anesthetized with sodium pentobarbital (60 mg/kg, 1 p ) and subjected to lateral fluid-percussion brain injury of moderate severity (2 4 atm ) centered over the left temporaparietal cortex (n=18), or "sham" treatment (anesthesia and surgery without injury) Animals are sacrificed at 1 , 6 and 24 hr post injury, brains removed, and tissue samples of left (injured) parietal cortex (LC), corresponding area in the contralateral right cortex (RC), cortex adjacent to injured parietal cortex (LA), corresponding adjacent area in the right cortex (RA), left hippocampus (LH) and right hippocampus (RH) are prepared. Total RNA is isolated and Northern blot hybridization was performed and the quantity of brain tissue IL-lβ mRNA is presented as percent relative radioactivity of IL-lβ positive macrophage RNA which was loaded on same gel. At 1 hr. following brain injury, a marked and significant increase in expression of IL- lβ mRNA is observed in LC (200±0.7% of positive control, n=6, p < 005 compared with sham animal). LH (24 5±0 9%, p < 005) and LA (21 5±3 1 %, p < 0 05) in the injured hemisphere, which remained elevated up to 6 hr. post injury in the LC (4 O±O 4%, n=6, p < 0 05) and LH (5 0±1.3%, p < 0.05) In sham or naive animals, no expression of IL- l β mRNA is observed in any of the respective brain areas These results indicate that following TBI. the temporal expression of IL-l β mRNA is regionally stimulated in specific brain regions These regional changes in cytokines, such as IL- l β play a role in the post-traumatic All publications, including but not limited to patents and patent applications, cited in this specification are herein incorporated by reference as if each individual publication were specifically and individually indicated to be incorporated by reference herein as though fully set forth The above description fully discloses the invention including preferred embodiments thereof Modifications and improvements of the embodiments specifically disclosed herein are within the scope of the following claims Without further elaboration, it is believed that one skilled in the are can, using the preceding description, utilize the present invention to its fullest extent Therefore the Examples herein are to be construed as merely illustrative and not a limitation of the scope of the present invention in any way The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows
