Abstract

This invention relates to the novel use of phenyl ureas in the treatment of disease states mediated by the chemokine, Interleukin-8 (IL-8).

Description

The IL-8 receptor antagonist
Invention field
The present invention relates to ring guanidine compound, its preparation method, its purposes in the disease of treatment IL-8, GRO α, GRO β, GRO γ, NAP-2 and ENA-78 mediation and the pharmaceutical composition that is used for this therapy of one group of novelty.
Background of invention
Interleukin 8 (IL-8) has many different titles, lure/activated protein-1 (NAP-1) such as neutrophilic granulocyte, come from monocytic neutrophilic chemotactic factor (MDNCF), the neutrophilic granulocyte activation factor (NAF) and T cell lymphocyte chemotactic factor.Interleukin 8 is the chemical inhibitor to neutrophilic granulocyte, basophil and T cell subsets, it is by comprising that the huge most nucleated cell of having a liking for cell, fibroblast, endotheliocyte and epithelial cell that are exposed to TNF, IL-1 α, IL-1 β or LPS produce, and by being exposed to LPS or being produced such as the neutrophilic granulocyte of the chemotactic factor of FMLP itself.M.Baggiolini etc., J.Clin.Invest.84,1045 (1989); J.Schroder etc., J.Immunol.139,3474 (1987) and J.Immunol.144,2223 (1990): Strieter etc., Science 243,1467 (1989) and J.Biol.Chem.264,10621 (1989); Cassatella etc., J.Immunol.148,3216 (1992).
Gro α, GRO β, GRO γ and NAP-2 also belong to chemokine alpha family, as IL-8, these chemotactic factors are also by titled with different titles, for example GRO α, β, γ are called as MGSA α, β and γ (melanoma growth-stimulating activity (Melanoma GrowthStimulating Activity)) respectively, see Richmond etc., J.Cell Physiology129,375 (1986) and Chang etc., J.Immunol 148,451 (1992).All chemotactic factors that have a α family that is located immediately at the ELR motif before the CXC motif all with the IL-8B receptors bind.
External, IL-8, Gro α, GRO β, GRO γ, NAP-2 and ENA-78 have promoted many functions, and they all demonstrate the granulocytic chemical attractants characteristic of neutrality, and IL-8 and GRO α demonstrate T-lymphocyte and basophil chemotactic activity simultaneously.In addition, IL-8 can induce the basophil of normal and atopic individuality to discharge histamine.In addition, IL-8 and GRO-α can induce the lysozyme of neutrophilic granulocyte to discharge and respiratory burst.IL-8 also demonstrates has increased Mac-1 (CD11b/CD18) surface expression at neutrophilic granulocyte when not having de novo albumen synthetic.This can help to increase the adhesive attraction of neutrophilic granulocyte and vascular endothelial cell.Many known diseases are to be feature with a large amount of neutrophil infiltration.Promote gathering and activating of neutrophilic granulocyte as IL-8, Gro α, GRO β, GRO γ and NAP-2, these chemotactic factors are relevant with the very large-scale acute and chronic inflammation disease that comprises psoriasis and rheumatic arthritis, Baggiolini etc., FEBS Lett.307,97 (1992); Miller etc., Crit.Rev.Immunol.12,17 (1992); Oppenheim etc., Annu Rev.Immunol.9,617 (1991); Seitz etc., J.Clin.Invest.87,463 (1991); Miller etc., Am.Rev.Respir.Dis.146,427 (1992); Donnely etc., Lancet 341,643 (1993).In addition, ELR chemotactic factor (those just in time before the CXC motif contain aminoacid ELR motif) is also relevant with antagonist, Strieter etc., and Science 258,1798 (1992).
External, by in conjunction with and activate the receptor of striding the G albumen coupling family of film for seven times, particularly pass through in conjunction with the IL-8 receptor, the most significant is the B receptor, and IL-8, Gro α, GRO β, GRO γ and NAP-2 induce neutrophilic granulocyte alteration of form, chemotaxis, particle release and respiratory burst, Thomas etc., J.Biol.Chem.266,14839 (1991) and Holmes etc., Science 253,1278 (1991).The development of this receptor family member's non-peptide micromolecule antagonist has had precedent, and its summary sees that R.Freidinger is at Progress inDrug Research, Vol.40, pp.33-98, Birkhauser Verlag, Basel1993.Therefore, the IL-8 receptor has been represented the target full of hope of novel anti-inflammatory drug development.
The feature of the human IL-8 receptor (77% homology) of two kinds of high-affinities is as follows: only with the bonded IL-8R α of IL-8 high-affinity, and the IL-8RB that IL-8 and GRO α, GRO β, GRO γ and NAP-2 is all had high-affinity.See Holmes etc., see above; Murphy etc., Science 253,1280 (1991); Lee etc., J.Biol.Chem.267,16283 (1992); LaRosa etc., J.Biol.Chem.267,25402 (1992); With Gayle etc., J.Biol.Chem.268,7283 (1993).
In this field, to the treatment also need can with IL-8 α or the bonded chemical compound of beta receptor.Therefore, the chemical compound of the inhibitor of IL-8 receptors bind will be useful to increase (it is responsible for neutrophilic granulocyte and T cell subsets chemotactic are arrived areas of inflammation) relevant disease with the IL-8 generation.
Summary of the invention
The invention provides a kind of method for the treatment of chemokine mediated diseases, wherein, chemotactic factor and IL-8 α or beta receptor combination, and the method comprises formula (I) compound or pharmaceutically acceptable salt thereof of using effective dose.Particularly this chemotactic factor is IL-8.
