Description

RECEPTOR ANTAGONISTS IL-8 FIELD OF THE INVENTION This invention relates to novel substituted benzoisothiazole compounds, pharmaceutical compositions, methods for their preparation, and use thereof for treating diseases mediated by IL-8, GROa, GROß, GRO ?, ENA-78 and NAP-2.
BACKGROUND OF THE INVENTION Many different names have been applied to interleukin (IL-8), as neutrophil activating / activating protein -1 (NAP-1), monocyte-derived neutrophil chemotactic factor (MDNCF), neutrophil activating factor (NAF), and T-cell lymphocyte chemotactic factor. Interleukin-8 is a chemoattractant for neutrophils, basophils, and a subset of T cells. It is produced by a majority of nucleated cells that include macrophages, fibroblasts, endothelial and epithelial cells exposed to TNF, IL-1a, IL-1β or LPS, and by neutrophils themselves when exposed to LPS or chemotactic factors such as FMLP. M. Baggiolini et al., J. Clin. Invest. 84, 1045 (1989); J. Schroder et al., J. Immunol. 139, 3474 (1987) and J. Immunol. 144. 2223 (1990); Strieter et al., Science 243. 1467 (1989) and J. Biol. Chem. 264, 10621 (1989); Cassatella et al., J. Immunol. 148, 3216 (1992). GROa, GROß, GRO? and NAP-2 also belong to the family chemokine. Similar to IL-8, these chemokines have been referred to by different names. For example GROa, ß,? have been referred to as MGSAa, ß and? respectively (Growth Stimulating Activity of Melanoma or Growth Stimulating Activity Melanoma), see Richmond et al., J. Cell Physiology 129, 375 (1986) and Chang et al., J. Immunol 148, 451 (1992). All chemokines in the family that possess the ELR motif directly preceding the CXC motif bind to the IL-8B receptor. IL-8, GROa, GROß, GRO ?, NAP-2 and ENA-78 stimulate a number of functions in vitro. All of them have been shown to have chemoattractant properties for neutrophils, whereas IL-8 and GROa have demonstrated chemotactic activity of basophils and T-lymphocytes. In addition IL-8 can induce histamine release from basophils of both normal and atopic individuals. GRO-a and IL-8 may also induce lysozomal enzyme release and neutrophil respiratory bursts. IL-8 has also been shown to increase surface expression of Mac-1 (CD11 b / CD18) on neutrophils without de novo protein synthesis. This may contribute to increased adhesion of neutrophils to vascular endothelial cells. Many known diseases are characterized by massive infiltration of neutrophils. Like IL-8, Groa, GROß, GRO? and NAP-2 promote the accumulation and activation of neutrophils, these chemokines have been : ¿.- .-: St. Iík. involved in a wide range of acute and chronic inflammatory disorders including psoriasis and rheumatoid arthritis, Baggiolini et al., FEBS Lett. 307, 97 (1992); Miller et al., Crit. Rev. Immunol. 12. 17 (1992); Oppenheim et al., Annu. Rev. Immunol. 9, 617 (1991); Seitz et al., J. Clin. Invest. 87. 463 (1991); Miller et al., Am. Rev. Respir. Dis 146, 427 (1992); Donnely et al., Lancet 341, 643 (1993). In addition, ELR chemokines (those that contain the ELR motif of amino acids just before the CXC motif) have also been implicated in angiostasis. Strieter et al., Science 258, 1798 (1992). In vitro, IL-8, GROa, GROß, GRO? and NAP-2 induce neutrophil shape change, chemotaxis, granule release, and respiratory bursts, binding to and activating receptors of the seven-transmembrane family, chained to G protein, particularly binding to IL-8 receptors, most notably the receptor B. 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 recipient family is unprecedented. For a summary consult R. Freidinger in: Proqress in Druq Research, Vol. 40, pp. 33-98, Birkhauser Verlag, Basel 1993. Hence, the IL-8 receptor represents a promising target for the development of new anti-inflammatory agents. Two IL-8 receptors of high human affinity (77% homology) have been characterized: IL-8Ra, which binds only to IL-8 with high affinity, and IL-8Rβ, which has high affinity for IL-8 as well as for GRO-a, GROß, GRO? and NAP-2. See Holmes et al., Supra; Murphy et al., Science 253. yes sj? & 1280 (1991); Lee et al., J. Biol. Chem. 267, 16283 (1992); LaRosa et al., J, Biol. Chem. 267, 25402 (1992); and Gayle et al., J. Biol. Chem. 268. 7283 (1993). There remains a need for treatment, in this field, for compounds that are capable of binding the IL-8 a or β receptor. Therefore, conditions associated with an increase in the production of IL-8 (which is responsible for chemotaxis of neutrophils and subsets of T cells in the inflammatory site) would benefit by compounds that are inhibitors of IL-8 receptor binding.

Accordingly, the present invention provides a method of treating a disease mediated by chemokine, wherein chemokine is that which binds to an IL-8 a or β receptor and which method comprises the administration of an effective amount of a compound of the invention. Formula I or a pharmaceutically acceptable salt thereof. In particular, the chemokines are IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78. The compounds of the formula (I) are administered in an amount sufficient to inhibit the function of the cytosine, in particular IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78, so that they are biologically regulated at normal levels of physiological function, or in certain cases at normal levels, to improve the state of the disease. The abnormal levels of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 for example in the context of the present invention, constitute: i) levels of free IL-8 greater than or equal to a picogram per ml; ii) any associated cell IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 of the above normal physiological levels; or iii) the presence of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 of the above basal levels in cells or tissues in which respectively IL-8, GROa, GROß, GRO? , NAP-2 or ENA-78. There are several disease states in which the production of excessive or unregulated IL8 is involved in the exacerbation and / or provocation of the disease. The chemokine-mediated diseases * bmlm < ^,. * ». ^, ^^^ ,, m tsmm - - ^ o - ** - *** »*** - include psoriasis, atopic dermatitis, arthritis, asthma, chronic obstructive pulmonary disease, respiratory distress syndrome in adults, intestinal disease inflammatory, Crohn's disease, ulcerative colitis, infarction, septic shock, endotoxic shock, negative gram sepsis, 5 toxic shock syndrome, cardiac and renal reperfusion injury, glumerulonephritis, thrombosis, graft reaction against host, Alzheimer's disease, rejections of allograft, malaria, restinosis, angiogenesis or unwanted release of hematopoietic stem cells, rhinovirus infections, and various indications of bone resorption, such as osteoporisis or osteoarthritis. The association of interleukin-8 and rhinovirus can be found in articles such as: Turner, et al., Clin. Infected Dis. (1988), 26 (4), 840-846; Sanders, et al., J. Vitral.

The association of interleukin-8 and osteoporosis can be found in articles such as: Streckfus ai al., J. Geronlol., Ser. A (1997), 52A (6), M343-M351; Hermann, T. W095 / 31722; and Chaudhary, et al., Endocrinology (Balíimore) (1992), 130 (5), 2528-34. These diseases are characterized mainly by massive neutrophil infiltration, T cell infiltration, or growth ^^ te ^ gi ^^^^ g ^ gagteaM ^^^^^ T ^? ^ g ^^ neovascular, and are associated with the production of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA- 78 which is responsible for the chemocytosis of neutrophils in the inflammatory site or the directional growth of the endoihelial cells. In contrast to inflammatory diseases (IL-8, GROa, GROß, GRO? Or NAP-5 2), it has the unique property of promoting neutrophil chemocytosis, including the release of but not limited to the release of elasiasa as well as the production and activation of superoxide. The a-chemokines, but paricularly, GROa, GROß, GRO? or NAP-2, which work in the lipo I or II receptor IL-8 can promote neovascularization of tumors by promoting the directional growth of the endoíeliales cells. Therefore, the inhibition of the induced chemolaxis of IL-8 or activation can lead to a direct reduction in neutrophil infiltration. Recent evidence also implicates the role of chemokines in the trafficking of HIV infections, Liííleman et al., Nalure 381, pp, 661 (1996) and Koup el al., Nalure 381, pp, 667 (1996). The present invention also provides a means of treatment, in an acute fixation, as well as prevention, in those individuals susceptible to CNS damage by the anhydrocyanin receptor compounds of chemokine of the formula (I). CNS injuries, as defined in the present, include open-head or rash injuries, such as surgery, or closed head injury, as a damage to the head region.
Also included in this definition is ischemic infarction, particularly in the brain area. Ischemic infarction can be defined as a focal neurological inflammation resulting from inadequate blood supply to a particular area of the brain, usually as a consequence of an embolus, anus, or local arelomaiosa closure of the blood spleens. The role of inflammatory cilocines in that area has arisen and the present invention provides a means for the potential treatment of said damages. Relatively low traffic, for acute damage as well as allergies, has been available. The TNF-a is a cilocin with proinflamal actions, including the expression of adhesion molecules of endoíeliales leukocytes. The leukocytes infiltrate the ischemic lesions of the brain and therefore the compounds that inhibit or reduce the levels of TNF are useful for the 15th year of cerebral ischemic damage. See Liu el al., Síoke, Vol. 25., No. 7, pp. 1481-88 (1994), the description of which is incorporated herein by reference. Models of closed head injury and trauma with mixed 5-LO / CO agents are described in Shohami et al., J. of Vaisic & 20 Clinical Physiology and Pharmacology, Vol. 3, No. 2, pp. 99-107 (1992), whose description is incorporated in the présenle by reference. It was found that the treatment that reduces the formation of edema improves the functional result in said treated animals.
The current evidence also indicates the use of IL-8 inhibitors in the irradiation of alellosclerosis. The first reference, Boisvert et al., J. Clin. Invest, 1998, 101: 353-363 shows, from the bone marrow transplantation, that the absence of IL-8 receptors in stem cells (and, therefore, 5 in monocytes / macrophages) leads to a reduction in the development of atherosclerotic plaques in mice deficient in LDL receptor.

The compounds of the formula (I) will be administered in a quantity sufficient to inhibit IL-8, bind IL-8 alpha or beta receptors, from which they bind to these receptors, as evidenced by a reduction in chemolaxis and neulrophilic acclivation. The discovery that the compounds of the formula (I) are inhibitors of the IL-8 bond is based on the effects of the compounds of the formulas (I) in the binding assays in vitro receptor described in the présenle. The compounds of the formula (I) have been shown to be inhibitors of IL-8 type II receptors. As used herein, the term "disease or disease state mediated by IL-8" refers to any disease state in which that IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 has a role, either through the production of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 themselves, or by IL-8, GROa, GROß, GRO ?, NAP-2 or ENA 78 that cause the release of monocyte, but not limitation to IL-1, IL-6 or FNT. A case of disease in which, for example, IL-1 is a major component, and whose production or action is exacerbated or secreted in response to IL-8, is therefore considered a disease condition mediated by IL-1. 8 As used herein, the term "disease or condition of chemokine-mediated disease" refers to any disease state in which a chemokine that binds to an IL-8 a or β receptor has a role, such but not limited to IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78. This includes a disease cycle in which IL-8 has a function, either in the production of IL-8 itself, or IL-8 that causes it to be released, to listen to monocyte, such as but not being limited to IL- 1, IL-6 or FNT. 15 A disease state in which, for example, IL-1 is a major component, and whose production or action is exacerbated or secreted in response to IL-8, will therefore be considered a disease context mediated by IL-1. 8 As used herein, the term "cytokine" refers to any secreted polypeptide that affects the functions of cells and is a molecule that modulates the inleractions between cells in the inflammatory or hematopoiemic immune response. A cilokine includes, but is not limited to, monocytes and lymphokines, despite the cells that produce them. For example, it is generally referred to that a monocline is produced and ^ &mM ^ ^ ... * m ~ "^ to * a * h * a ^ <. ^^^. ,, - ^ A ^^^ secret by a mononuclear cell, such as a macrophage and / or Several cells, however, also produce monocytes, such as natural killer cells, fibroblasts, basophils, neutrophils, endothelial cells, cerebral astrocytes, bone marrow stryromatic cells, epidermal keralinocytes, and B-lymphocytes. lymphokines to be produced by lymphocyte cells Examples of cytokines include, but are not limited to, interleukin-1 (IL-1), inerieucin-6 (IL-6), inerieucin-8 (IL-8), factor lumoral-alpha necrosis (TNF-a) 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 that modulates the interactions between the cells in the immune, inflammatory or haematopoietic response, similar to the term no "cyanococline." A chemokine is secreted mainly from the cell membranes and causes the chemocytosis and acyivation of specific white blood cells and leukocytes, neulrophils, monocytes, macrophages, T cells, B cells, endoihelial cells, and smooth muscle cells. . Examples of chemokines include, but are not limited to, IL-8, GRO-a, GRO-β, GRO- ?, NAP-2, ENA-78, IP-10, MIP-1a, MlP-β, PF4, and MCP 1, 2 and 3.

BIOLOGICAL EXAMPLES The chemokine inhibitory effects of IL-8, and GRO-a of the compounds of the present invention are determined by the following in vitro assay: Receptor binding assays: [125 I] IL-8 (human recombinance) is obtained from Amersham Corp., Arlingin Heighis, IL, with specific activity of 2000 Ci / mmoles. The Gro-a is made by NEN-New England Nuclear. All other chemicals are J ^^ jg of analytical degree. High levels of recombinant human IL-8 type receptors a and β were individually expressed in Chinese hamster ovary cells as previously described (Holmes, et al., Science, 1991, 253, 1278). The Chinese hamster ovary membranes were homogenized according to the protocol described above (Haour, et al., J Biol Chem., 249 pp. 2195-2205 (1974)) Except that the homogenization pH regulator was changed to 10mm. of tris-HCL, 1 mm of MgSO4, 0.5 mm of EDTA (ethylenediaminetetraacetic acid), 1 mm of PMSF (a-luenesulfonyl fluoride), 0.5 mg / L of leupepinine, pH 7.5 The concentration of membrane proteins is determined using the Pierce Co. microassay kit using bovine serum albumin as a standard All assays were carried out in a 96-well microplate format.Each reaction mixture contains 125I-IL-8 (0.25Nm) 0/1251 Gro-a and 0.5 μg / ml of IL-8Ra or 1.0 μg / ml of membranes and IL-8Rβ in 20 mm of Bis-Trispropane and 0.4 mm of pH regulators of Tris HCl, Ph 8.0, containing 1.2mm of MgSO4, 0.1 mm of EDTA, 25 mm of NaCl, and 0.03% of CHAPS, plus the drug or compound of interest, which has been predisposed in DMSO to reach a final concentration of 0.01 nM and 100 uM. The assay was initiated by the addition of 125 I-IL-8. After 1 hour at ambient temperature, the plate was cultured using a Tamtec 96-well harvester in a fiberglass filter blocked with 1% polyethyleneimine-0.5% BSA and washed 3 times with 25 mm NaCl, 10 mm TrisHCI, 1 mm MgSO4, 0.5 mm EDTA, 0.03% CHAPS, pH 7.4. The filter then It was dried and counted in the liquid scintillation column of beia plate. The IL-8 receptor Ra, recombinase, or lipo I, is also referred to herein as the non-permissive receptor and reference is made to the IL-8Rβ receptor, recombinanle, or lipo II, as the permissive receptor. It has been found that representative compounds of formula (I), examples 1 to 8, have positive inhibitory activity of < 30 μmg in this assay.
Chemotaxis Assay The in vitro inhibitory properties of said compounds are determined in the neutrophil chemotaxis assay as described in Currenl Protocole in Immunology, vol. I, Suppl 1, Unit 6.12.3, the description of which is incorporated herein by reference in its tolality. The neutróphils were isolated from human blood as described in Currenl Prolocols in Immunology Vol. I, Sup / 1. 1 Unit 6: 12.3, whose description is incorporated herein by reference in its illegality. The chemoattractants IL-8, GRO-a, GRO-β, GRO-? and NAP-2 are placed in the lower chamber of a chamber of 48 multiple cavities (Neuro Probé, Cabin John, MD) at a concentration between 0.1 and 100 nM. The two chambers are separated by a polycarbonate filter of 5 um. When testing the compounds of this invention, they are mixed with the cells (0.001-1000 nM) just before the addition of the cells in the upper chamber. The incubation may proceed from around 45 and 90 min at about 37 ° C in a humidified incubator with 5% C02. At the end of the incubation period, the polycarbonate membrane is removed and the upper area is washed, the membrane then Use the Diff Quick protocol (Baxter Producís, McGaw Park, IL, USA). Cells that chemokine chemoklaxis were visualized using a telescope. Generally, 4 fields were counted for each sample, these numbers are averaged to give the average number of cells that have migrated. Each sample is tested in triplicate and each compound is repeated at least 4 times. For certain cells (posiivoid cells), no compound was added, said cells represented the maximum chemolytic response of the cells. In the case where a negative conirol is desired (not reduced), chemokine is not added to the lower chamber. The difference between the posilive growth and the negative balance represent the chemotactic activity of the cells.
Elastase Release Assay The compounds of this invention were tested for their ability to prevent the release of elasasis from human nephrophiles. Neulrophiles are isolated from human blood as described in Curreni Prolocols in Immunology Vol. I. Suppl 1 Unit 7.23.1. The PMNs 0.88 x 106 cells Suspended in Ringer's solution (NaCl 118, KCl 4.56, NaHC03 25, KH2P04 1.03, glucose 11.1, HEPES 5 mm, pH 7.4) are placed in each well of a 96-well plate in a volume of 50 ul. To this plate is added the test compound (0.001 - 1000 nM) in a volume of 50 ul, the cyclocalasin B in a volume of 50 ul (20ug / ml) and the Ringer's pH regulator in a volume of 50ul. Said cells could be calendered (37 ° C, 5% C02.95% RH) for 5 min. before it was added IL-8 GROa, GROß.GRO? or NAP-2) at a final concentration of 0.01-1000 mM. The reaction could proceed for 45 min. before a 96-well plate (800 xg 5 min.) and 100 ul of the removed supernatant were centrifuged. Said supernatant was added to a second 96-well plate followed by an artificial elastase substrate (MeOSuc-Ala-Ala-Pro-Val-AMC, Nova Biochem, La Jolla, CA) at a final concentration of 6 mg / ml dissolved in 10 regulated phosphate saline solution. Immediately, the plate was placed in a fluorescent 96-well plate reader (Cyofofor 2350, Millipore, Bedford, MA) and the data were collected at 3 min intervals. according to the method of Nakajima et al J. Biol Chem 254 4027 (1979). The amount of elasilase released from the PMNs is calculated by measuring the rate of degradation of MeOSuc-Ala-Ala-Pro-Val-AMC.

Briefly, the hearts are bisected just below the level of the atria and the base of the heart plus the aortic root 10 are ligated for analysis. After balancing the tissue in the OCT compound during the night, the hearts are immersed in the OCT compound in a cryostat mandrel (Bright Instrument Company Ltd., R.U) with the aorta facing the mandrel. The ice freezes around the mandrel with dry ice. The hearts are then sectioned perpendicular to the axis of the aorta, starting at the heart and proceeding in the direction of the aorta. Once the aortic root has been idenified by the appearance of fresh valve leaflets, alternating 10mm sections are ligated and mounted on gelatinized slides. The sections are air-dried for 1 hour and subsequently briefly rinsed in 60% isopropyl alcohol. Sections are stained with oil red O, coated with Mayer hemaxililin, covered using glycerol gelatin and sealed with nail varnish. nH ¿g ^ i. . . ^^ - ^ Av? É? *.
Quantification of atherosclerosis in the aortic root. Ten alternate sections of the aortic root are observed using an Olympus BH-2 microscope equipped with a 4x objective and a video camera (Hitachi, HV-C10). 24-bit color images are acquired and analyzed using a PC (Daiacell Pentium P5-133, Daiacell Berks, UK) coupled with a frame recording labyrinth (Snapper, Acive Imaging Lid, Berks, UK) and the software is run Optimums (version 5.1, Optimums Corp., WA, USA). The images were captured under identical conditions of the microscopes, camera and PC. The quantification of the lesion-lesion areas is carried out by hand drawing around the lesion using the Optimas software. The three colors are set to quantify the areas that are stained red in the lesions. The absolute values for the cross-sectional areas of the lesions and the red-stained areas are obtained by software calibration using an image of the grid on a hemocytometry slide.
