IL-8 RECEPTOR ANTAGONISTS

FIELD OF THE INVENTION

Thi.s invention relates to a novel group of phenyl urea compounds, processes for the preparation thereof, the use thereof in treating IL-8. GROα. GROβ. GROγand NAP-2 mediated diseases and pharmaceutical compositions lor use in such therapy

BACKGROUND OF THE INVENTION

Many different names have been applied to Interleukin-8 (IL-8). such as neutrophil attractant/activauon protein- 1 (NAP-1). monocyte derived neutrophil chemotactic factor (MDNCF), neutrophil activating factor (NAF). and T-cell lymphocyte chemotactic factor. lnierleukin-8 i.s a chemoattractant for neutrophils. ba.sophil.s. and a sub.sct of T-cells. It is produced by a majority of nucleated cells including macrophages, fibroblasts, endothehal and epithelial cells exposed to TNF, IL- l α, IL-lβ 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).

Groα, GROβ. GROγ and NAP-2 also belong to the chemokinc α family. Like IL-8 these chemokincs have also been referred lo by different names For instance GROα, β, γ havc been referred to as MGSAα. β and γ respectively (Melanoma Growth Stimulating Activity). see Richmond et al. J. Cell Phy.siologv 129. 375 ( 1 86) and Chang ei al. J. Immunol 148. 45 1 ( 1 92). All ot the chcmokines of the α-lamily which possess the ELR motif directly preceding the CXC motif bind to the 1L-8 B receptor

IL-8. Groα. GROβ. GROγ and NAP-2 stimulate a number ol lunctions in vitro have all been shown to have chcmoattraciani properties lor neutrophils. while IL-8 and GROσ have demonstrated T-lymphocy.cs. and basophiles chemotactic activity In addition IL-fc can induce histamine release irom basophils Iron, both normal and atopic individuals GRO-α and IL-8 can in addition, induce lyso omal cn/yme release and respiratory burst from neutrophils IL-8 has also been shown to increase ihe surface expression of Mac- 1 (CD I l b/CD 1 ) on neutrophils without de protein synthesis This may contribute to increased adhesion oi the neutrophils to vascular cndothclial cells Many known diseases arc characterized b\ massive neutrophil infiltration As IL-8. Groα, GROβ. GROγ and NAP- 2 promote the accumulation and activation of neutrophils. these chcmokines have been implicated in a wide range ol acute and chronic inflammatory disorders including psoriasis and rheumatoid arthritis.

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 ot the seven-transmembrane. G-protem-linked lamily, in particular by binding to IL-8 receptors, most notably the B-receptor Thomas et al , J. Biol. Chem. 26 14839 ( 1991). and Holmes et al . Science 253. 1278 ( 1991 ) The development of non-peptide small molecule antagonists tor members ol this receptor lamily 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 ol novel anti-inflammatory agents Two high aflinity human IL-8 receptors (77% homology) have been characteπzed IL-

8Rα, which binds only IL-8 with high affinity, and IL-8Rβ, which has high affinity tor IL-8 as well as lor GRO-α. GROβ, GROγ and NAP-2 See Holmes et al . supra: Murphy et al , Science 253. 1280 ( 19 1 ): Lee et al.. J Biol. Chem. 267. 16283 ( 199?) LaRosa et al , ! Biol Chem 267. 25402 ( 1992). and Gayle et al , J. Biol Chem 268. 7283 ( 1993) There remains a need tor treatment, in this field, tor compounds which are capable ol binding to the IL-8 α or β receptor Therefore, conditions associated with an increase in IL-8 production (which is responsible lor chemotaxis ot neutrophil and T-cclls subsets into the inflammatory site ⁾ would benefit by compounds which arc inhibitors ol IL-8 receptor binding

METHOD OF TREATMENT

The compounds of Formula (I), (la), (II) and (III), or a pharmaceutically acceptable salt thereol can be used in the manufacture of a medicament for the prophylactic or ihcrapeuuc treatment of any disease stale in a human, or other mammal, which is exacerbated or caused by excessive or unregulated IL-8 cytokine production by such mammal's cell, uch as but not limited lo monocyies and/or macrophages. or other chcmokines which bind to the IL-8 α or β receptor, also rclcncd lo as the type I or type II receptor

For purposes herein, the compounds of Formula (I), (la). (lb). ( Ic). (II) and (III) all have ihe same dosages, and dosage formulations as that of Formula (I ) are used interchangeably Accordingly, the present invention provides a method ot treating a chemokine mediated disease, wherein the chcmokinc is one which binds to an IL-8 or β recepior and which method comprises administering an ctteciivc amouni ol a compound ol Formula (I) or a pharmaceutically acceptable sail thereol In particular, the chcmokines ai s IL-X. GROα. GROβ. GROγ or NAP-2

The compounds of Formula (p are administered in an amouni sufficient to inhibit cyiokinc tunction. in particular IL-8.GROα. GROβ. GROγ or NAP-2 . such that they are ologically regulated down to normal levels ol physiological tunction. or in some case lo

subnormal levels, so as to ameliorate the disease siatc Abnormal levels of IL-8. GROα. GROβ, GROγ or NAP-2 tor instance in the context of the present invention, consuiute: (ι) levels of free IL-8 greater than or equal to I picogram per mL: (ii) any cell associated IL-8. GROα, GROβ, GROγ or NAP-2 above normal physiological levels: or (iii)ιhe presence of IL- 8, GROα, GROβ. GROγ or NAP-2 above basal levels in cells or tissues which IL-8, GROα, GROβ. GROγ or NAP-2respectively, is produced.

There are many disease states in which excessive or unregulated IL-8 production is implicated in exacerbaύng and/or causing the disease. Chemokine mediated diseases include psoriasis, atopic dermatitis, arthritis, asthma, chronic obstructive pulmonary disease, adult respiratory distress syndrome, inflammatory bowel disease, Crohn's disease, ulcerativc colitis. stroke, septic shock, endotoxic shock, gram negative sepsis, toxic shock syndrome, cardiac and renal reperfusion injury, glomerulonephritis. thrombosis, graft vs. host reaction, alzheimers disease, allograft rejections, malaπa. restinosis, angiogenesis or undesired hematopoietic stem cells release.

These diseases are primarily characterized by massive neutrophil infiltration, T-ccll infiltration, or neovascular growth, and are associated with increased IL-8, GROα, GROβ, GROγ or NAP-2 production which is responsible for the chemotaxis of neutrophils into ihe inflammatory site or the directional growth of endothelial cells. In contrast to other inflammatory cytokines (IL- 1, TNF. and IL-6), IL-8. GROα, GROβ. GROγ or NAP-2 has the unique property of promoting neutrophil chemotaxis, enzyme release including but not limited to elastase release as well as superoxide production and activation The α-chcmokines but particularly. GROα. GROβ. GROγ or NAP-2. working through the IL-8 type 1 or II receptor can promote the neovascularizaiion of tumors by promoting ihe directional growth ol endothelial cells. Thcrelorc. die inhibition of IL-8 induced chemotaxis or activation would lead to a direct reduction in the neutrophil infiltration.

The compounds of Formula (I) arc administered in an amount sufficient to inhibit IL- binding to ihe IL-8 alpha or beta receptors, from binding lo these receptors, such as cvidencetl by a reduction in neutrophil chemotaxis and activation. The discovery thai the compounds ol Formula (I) are inhibitors of IL-8 binding is based upon the cllccis ol the compounds ol Formulas (I) in the in vitro receptor binding assays which are described herein. The compounds of Formula (I) have been shown to be dual inhibitors ot both recombinant type I and type II IL-8 receptors. Preferably the compounds are inhibitors of only one receptor, preferably Type II

As used herein, the term "IL-8 mediated disease or disease state" relers to any and all disease states in which IL-8. GROα. GROβ, GROγ or NAP-2 plays a role, cither by production of IL-8, GROα, GROβ, GROγ or NAP-2 themselves, or by IL-8. GROα, GROβ, GROγ or NAP-2 causing another monokine to be released, such as bui not limited to IL- 1. IL- 6 or TNF. A disease state in which, for instance, IL- 1 is a major component, and whose production or action, is exacerbated or secreted in response to IL-8. would theref re be considered a disease stated mediated by IL-8

As used herein, the term "chemokine mediated disease or disease stale" relers to any and all disease states in which a chemokine which binds to an IL-8 α or β receptor plays a role such as but not limited to IL-8, GRO-α, GRO-β, GRO-γ, or NAP-2 This would include a disease state in which, IL-8 plays a role, either by production of IL-8 itself , or by IL-8 causing another monokine to be released, such as but not limited to IL- 1. IL-6 or TNF A disease stale in which, for instance, IL- 1 is a maior component, and whose producuon or action, is exacerbated or secreted in response to IL-8, would therefore be considered a disease staled mediated by IL-8.

As used herein, the term "cytokine" refers to any secreted polypcptidc d al all ecus the funcuons of cells and is a molecule which modulates interactions between cells in ihe immune. inflammatory or hematopoietic response. A cytokine includes, bui is not limned to. monokincs and lymphokines, regardless of which cells produce them For instance, a monokine is generally referred to as being produced and secreted by a mononuclcar cell, such as a macrophage and/or monocytc. Many other cells however also produce monokincs. such as natural killer cells, fibroblasts. basophils, neutrophils. endothelial cells, brain astrocyies. bone marrow siromal cells, epideral keratinocytes and B-lymphocyics Lymphokines are general! \ rclerrcd to as being produced by lymphocyte cells Examples ot cyiokincs include, but aie not limited to. Inicrleukιn- 1 (IL- 1 ). Intcrlcukm-6 (IL-6), Inicrlcukιn-8 (1L-8). Tumoi Neciosis Factor-alpha (TNF-α) and Tumor Necrosis Factor beta (TNF- 1..)

As used herein, ϋie term "chemokine" relers to any secreted polypcptidc thai al lecis die tuncuons ol cells and is a molecule which modulates interactions beiween cells in the immune inflammatory or hematopoieuc response, similar to the term cyiokine" A chcmokinc is pπmaπly secreted through cell iransmcmbrancs and causes chemotaxis and activation ol specific while blood cells and leukocytes, neutrophils. monocyics. macrophages. T-cells. B- cells, endothelial cells and smooth muscle cells Examples ol chcmokines include, but aic not limited to. IL-8. GRO-α, GRO-β. GRO-γ. NAP-2. IP- 10. MlP- l α. MlP-β.
