The present invention describes new substituted quinolines that inhibit the protein kinase Syk (spleen tyrosine kinase), the preparation and formulation thereof and their use for preparing a medicament.
Syk is an intracellular tyrosine kinase that has an important mediator function in the signal transduction of different receptors in B-cells, mast cells, monocytes, macrophages, neutrophils, T-cells, dendritic cells and epithelial cells. The receptors in which Syk performs an important function in signal transduction include for example the receptors for IgE (Fc{acute over (ε)}RI) and IgG (FcγR1) on mast cells and B cells, the B-cell receptor (BCR) and the T-cell receptor (TCR) on B- and T-cells, the ICAM1 receptor (ICAM1R) on epithelial cells of the respiratory tract, the DAP12-receptor on natural killer cells, dendritic cells and osteoclasts, the dectin 1-receptor on a subpopulation of T-helper cells (Th-17 cells), as well as the integrin receptors for β1-, β2- and β3-integrins on neutrophils, monocytes and macrophages (Wong et al.; Expert Opin. Investig. Drugs (2004) 13(7), 743-762; Ulanova et al.; Expert Opion. Ther. Target (2005) 9(5); 901-921; Wang et al.; J. Immunol. (2006) 177, 6859-6870; Leib and Gut-Landmann et al.; Nature Immunology (2007) 8, 630-638; Slack et al., European J. Immunol. (2007) 37, 1600-1612). The molecular processes are described best for the signal transduction of the Fc{acute over (ε)}RI. In mast cells the binding of IgE to Fc{acute over (ε)}RI causes the cross-linking of IgE-receptors and the recruiting and activation of Lyn (a tyrosine kinase from the Src family). Active Lyn phoshorylates so-called ITAM motifs, which are present in many of the receptors listed above, and thereby generates binding sites for the SH2-domain of Syk. As a result of the binding to the ITAM motif Syk is activated and then phosphorylates various substrates which are needed for the release of allergic and inflammatory mediators such as e.g. histamine and β-hexosamidase (BHA), as well as for the synthesis of lipid mediators, such as e.g. prostaglandins and leukotrienes.
In view of its central function in different signal transduction pathways Syk has been discussed as a therapeutic target for different diseases such as e.g. allergic rhinitis, asthma, autoimmune diseases, rheumatoid arthritis, osteopenia, osteoporosis, COPD and various leukaemias and lymphomas (Wong et al.; Expert Opin. Investig. Drugs (2004) 13(7), 743-762; Ulanova et al.; Expert Opion. Ther. Target (2005) 9(5); 901-921; Sigh and Masuda. Annual Reports in Medicinal Chemistry (2007) Vol 42; 379-391; Bajpai et al.; Expert Opin. Investig. Drugs (2008) Vol 15 (5); 641-659; Masuda and Schmitz; PPT (2008) Vol 21; 461-467; Riccaboni et al., Drug Discovery Today (2010) Vol 00 (O); 517-530; Efremov and Luarenti, Expert Opin Investig Drugs. (2011) 20(5):623-36).
Allergic rhinitis and asthma are diseases associated with allergic reactions and inflammatory processes and involving different cell types such as e.g. Mast cells, eosinophils, T-cells and dendritic cells. After exposure to allergens has occurred, the high affinity immunoglobulin receptors for IgE (Fc{acute over (ε)}RI) and IgG (FcγR1) are activated and induce the release of pro-inflammatory mediators and bronchoconstrictors. An inhibitor of the Syk kinase activity should thus be able to inhibit these steps.
Rheumatoid arthritis (RA) is an autoimmune disease in which the bones and ligaments structures surrounding the joints are progressively destroyed. In the pathophysiology of RA, B-cells play a significant role, as has been demonstrated for example by the therapeutic use of rituximab, a B cell-depleting antibody. In addition to the function of Syk in the signal transduction of the BCR (which after being stimulated also induces the release of pro-inflammatory mediators), Syk also plays an important part in the maturation and proliferation of B cells (Cheng et al. Nature (1995) 378, 303-306, Cornall et al., PNAS (2000) 97(4), 1713-1718). An inhibitor of the Syk kinase activity may thus offer a therapeutic option for the treatment of autoimmune diseases such as RA and diseases with an increased proliferation of B cells, such as e.g. B-cell lymphomas.
Chronic obstructive pulmonary disease (COPD) is characterised by a successive deterioration in lung function and chronic inflammation of the airways, which is initiated and produced by noxious substances of all kinds and contributes to the maintenance of the course of the disease. At a cellular level, in COPD there is in particular a multiplication of T-lymphocytes, neutrophils, granulocytes and macrophages. In particular, there is an increase in the number of CD8-positive lymphocytes, that is directly connected with the impairment of lung function. Another characteristic of COPD are acute deteriorations in lung function (exacerbations), characterised by viral (e.g. Rhinovirus), or bacterial (e.g. Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis) infections.
In view of the pro-inflammatory function of Syk in macrophages, T-cells and neutrophils as described above (see: Wong et al.; Expert Opin. Investig. Drugs (2004) 13(7), 743-762; and references cited therein) an inhibitor of the Syk kinase activity could be a new therapeutic approach to the treatment of the inflammatory processes that underlie COPD. It has also been shown that Syk in epithelial cells of the respiratory tract is involved in the ICAM1R-mediated uptake and subsequent replication of the Rhinovirus and that a si-RNA against Syk blocks these steps (Wang et al.; J. Immunol. (2006) 177, 6859-6870; Lau et al.; J. Immunol. (2008) 180, 870-880). Thus, an inhibitor of the Syk kinase activity could also be used therapeutically in exacerbations caused by Rhinoviruses.
Various studies suggest that Syk is involved in the malignant transformation of lymphocytes (summarised in Sigh and Masuda, Annual Reports in Medicinal Chemistry (2007) Vol 42; 379-391). A TEL-Syk fusion protein with a constitutive Syk activity transformed B cells of a patient with myelodysplastic syndrome, a constitutively active ITK-Syk fusion protein was isolated from patients with peripheralT-cell lymphomas (PTCL). Moreover, constitutively active Syk was found in B-cell lymphoma cells of patients, especially in B-lineage acute lymphoblastic leukemia (B-ALL), follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), mantle cell lymphomas and B cell Non-Hodgkin Lymphomas (NHLs) as well as in acute myeloid leukemia (AML). On the basis of these data it seems that Syk is a proto-oncogene in haematopoietic cells and represents a potential target for the treatment of certain leukaemias and lymphomas.
Idiophathic thrombocytoenic purpura (ITP) is an autoimmune disease in which IgG autoantibodies against antigens present on platelets bind to and destroy platelets. Patients with ITP have an accelerated clearance of circulating IgG-coated platelets via macrophages in the spleen and the liver. In view of the pro-inflammatory FcγR-mediated function of Syk in macrophages an inhibitor of Syk is considered to have a therapeutic benefit in FcγR-mediated cytopenias like ITP. Indeed the Syk inhibitor R788 (R406) improved platelet counts in a single center, oben label study in patients with ITP (Podolanczuk et al; Blood (2009) 113, 3154-3169).
Bullous pemphigoid (Ujiie et al. Journal of Dermatology 2010; 37: 194-204) is a chronic, autoimmune, subepidermal, blistering skin disease that rarely involves mucous membranes. Bullous pemphigoid is characterized by the presence of immunoglobulin G (IgG) autoantibodies specific for the hemidesmosomal bullous pemphigoid antigens BP230 (BPAg 1) and BP180 (BPAg2). Pemphigus vulgaris (Venugopal et al. Dermatol. Clin. 2011; 29:373-80) is a chronic blistering skin disease with skin lesions that are rarely pruritic, but which are often painful. Pemphigus vulgaris is an autoimmune disease caused by IgG autoantibodies directed against both desmoglein 1 and desmoglein 3 resulting in the loss of cohesion between keratinocytes in the epidermis. It is characterized by extensive flaccid blisters and mucocutaneous erosions. In both diseases IgG autoantibodies bind to Fc receptor gamma (FcR9) and activate FcR9 and downstream signaling via Syk kinase. Thus, an inhibitor of the Syk kinase activity which blocks downstream signalling of the FcR9 could be used therapeutically to treat patients with bullous pemphigoid and pemphigus vulgaris. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease which can affect basically any organ of the body. It is characterised by a multisystem inflammation of the microvascular and the presence of autoantibodies. FcγR-deficient mice are protected from several aspects of SLE in disease-related preclinical models, suggesting that an inhibitor of Syk can have a therapeutic benefit in SLE in view of the pro-inflammatory FcγR-mediated function of Syk in various cells.
U.S. Pat. No. 3,928,367, U.S. Pat. No. 4,017,500, U.S. Pat. No. 4,115,395 and U.S. Pat. No. 4,260,759 describe 5-amino-1,6-naphthyridines with an antifungal and antibacterial activity. WO 9918077 describes 5-piperazinyl-1,6-naphthyridines as serotonin antagonists. U.S. Pat. No. 7,321,041 describes substituted 1,6-naphthyridines as SYK-inhibitors, however these 1,6-naphthyridines have a completely different substitution pattern from the compounds according to the invention. PCT/EP1011050871 discloses 1,6-naphthyridines which are substituted in 5- and in 7-position. In contrast to that the instant invention concerns 5-,7-disubstituted quinolines instead of naphthyridines.

Surprisingly it has now been found that quinolines of formula 1 are particularly suitable for the treatment of respiratory complaints, allergic diseases, osteoporosis, gastrointestinal diseases, autoimmune diseases, inflammatory diseases and diseases of the peripheral or central nervous system, particularly for the treatment of asthma, allergic rhinitis, rheumatoid arthritis, allergic dermatitis and COPD.

The following Examples were prepared analogously to the methods of synthesis described above. These compounds are suitable as SYK inhibitors and have IC50-values of less than or equal to 1 μmol. The IC50-values of the individual example substances are shown in the following Table 1 and were experimentally determined as follows:
Syk Kinase Test
Recombinant human Syk (amino acids 342-635) was expressed as a fusion protein with an N-terminal GST tag, affinity-purified and deep-frozen at a concentration of approx. 50-100 μM in test buffer (25 mM HEPES pH7.5; 25 mM MgCl2; 5 mM MnCl2; 50 mM KCl; either 0.2% BSA or 0.2% HSA; 0.01% CHAPS; 100 μM Na3VO4; 0.5 mM DTT) and 10% glycerol at −80° C. until use.
The catalytic activity of the GST-Syk kinase fusion protein was determined using the Kinase Glo® Luminescence Kinase test (Promega; V6712). In this homogeneous test the amount of ATP remaining after the kinase reaction is quantified by a luciferin-luciferase reaction using luminescence. The luminescence signal obtained correlates with the amount of ATP still present and thus correlates inversely with the activity of the protein kinase.
Method
The test compounds were dissolved in 100% DMSO at a concentration of 10 mM and diluted in DMSO to a concentration of 1 mM. All further dilutions of the substances were carried out with 7.5% DMSO in test buffer until a concentration was reached which was 7.5 times above the final test concentration (final concentration of the compounds: 30 μM to 1 nM). 2 μl aliquots of these dilutions were transferred into a 384-well Optiplate (Perkin Elmer, #6007290). GST-Syk was diluted to 6.0 nM in the test buffer and 10 μl of this dilution were used in the kinase test (final concentration of Syk=4 nM in a total volume of 15 μl). After 15 minutes incubation at room temperature 3 μl of a mixture of 750 nM ATP and 100 μg/ml poly (L-Glutamic acid L-Tyrosine 4:1), Fluka #81357) in test buffer were added to each well and the incubation was continued for a further 60 minutes at room temperature.
Positive controls are the reaction mixtures that contain no test substance; negative controls (blanks) are reaction mixtures that contain no kinase.
After 60 minutes, 10 μl Kinase-Glo® solution (Promega, Cat. #V6712) (heated to room temperature) were added to each well and incubation was continued for a further 15 minutes. The plates were read in a Microplate Scintillation and Luminescence Counter (Canberra Packard GmbH).
Data Evaluation and Calculation:
The output file of the “Counter” is a text file that contains the well number and measured counts in two columns. For data evaluation and calculation, the measurement of the negative control was set as 100% inhibition and the measurement of the positive control was set as 0% inhibition. Based on this values the % inherent value for the measurement of each substance concentration was calculated using an “MS-Excel-VB macro”. Normally, the % inhibition values calculated are between 100% and 0% inhibition values but may also occur outside these limits in individual cases. The IC50 values were calculated from the % inhibition values using “GraphPadPrism” software (Version 5) (GraphPad Software Inc.).

Examples of iNOS-inhibitors within the scope of the present invention may also include antisense oligonucleotides, particularly those antisense oligonucleotides which bind iNOS-coding nucleic acids. For example, WO 01/52902 describes antisense oligonucleotides, particularly antisense oligonucleotides, which bind iNOS coding nucleic acids, for modulating the expression of iNOS. iNOS-antisense oligonucleotides as described particularly in WO 01/52902 may therefore also be combined with the PDE4-inhibitors of the present invention on account of their similar effect to the iNOS-inhibitors.
Suitable HMG-CoA reductase inhibitors (also called statins) which may be preferably used in double or triple combinations with the compounds of formula 1 are selected from among Atorvastatin, Cerivastatin, Flurvastatin, Lovastatin, Pitavastatin, Pravastatin, Rosuvastatin, Simvastatin, optionally in form of their pharmaceutically available acid addition salts, prodrugs, solvates or hydrates thereof.
Suitable forms for administration are for example tablets, capsules, solutions, syrups, emulsions or inhalable powders or aerosols. The content of the pharmaceutically effective compound(s) in each case should be in the range from 0.1 to 90 wt. %, preferably 0.5 to 50 wt. % of the total composition, i.e. in amounts which are sufficient to achieve the dosage range specified hereinafter.
The preparations may be administered orally in the form of a tablet, as a powder, as a powder in a capsule (e.g. a hard gelatine capsule), as a solution or suspension. When administered by inhalation the active substance combination may be given as a powder, as an aqueous or aqueous-ethanolic solution or using a propellant gas formulation.
Preferably, therefore, pharmaceutical formulations are characterised by the content of one or more compounds of formula 1 according to the preferred embodiments above.
It is particularly preferable if the compounds of formula 1 are administered orally, and it is also particularly preferable if they are administered once or twice a day. Suitable tablets may be obtained, for example, by mixing the active substance(s) with known excipients, for example inert diluents such as calcium carbonate, calcium phosphate or lactose, disintegrants such as corn starch or alginic acid, binders such as starch or gelatine, lubricants such as magnesium stearate or talc and/or agents for delaying release, such as carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate. The tablets may also comprise several layers.
Coated tablets may be prepared accordingly by coating cores produced analogously to the tablets with substances normally used for tablet coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar. To achieve delayed release or prevent incompatibilities the core may also consist of a number of layers. Similarly the tablet coating may consist of a number of layers to achieve delayed release, possibly using the excipients mentioned above for the tablets.
Syrups containing the active substances or combinations thereof according to the invention may additionally contain a sweetener such as saccharine, cyclamate, glycerol or sugar and a flavour enhancer, e.g. a flavouring such as vanillin or orange extract. They may also contain suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.
Capsules containing one or more active substances or combinations of active substances may for example be prepared by mixing the active substances with inert carriers such as lactose or sorbitol and packing them into gelatine capsules. Suitable suppositories may be made for example by mixing with carriers provided for this purpose, such as neutral fats or polyethyleneglycol or the derivatives thereof.
Excipients which may be used include, for example, water, pharmaceutically acceptable organic solvents such as paraffins (e.g. petroleum fractions), vegetable oils (e.g. groundnut or sesame oil), mono- or polyfunctional alcohols (e.g. ethanol or glycerol), carriers such as e.g. natural mineral powders (e.g. kaolins, clays, talc, chalk), synthetic mineral powders (e.g. highly dispersed silicic acid and silicates), sugars (e.g. cane sugar, lactose and glucose), emulsifiers (e.g. lignin, spent sulphite liquors, methylcellulose, starch and polyvinylpyrrolidone) and lubricants (e.g. magnesium stearate, talc, stearic acid and sodium lauryl sulphate).
For oral administration the tablets may, of course, contain, apart from the above-mentioned carriers, additives such as sodium citrate, calcium carbonate and dicalcium phosphate together with various additives such as starch, preferably potato starch, gelatine and the like. Moreover, lubricants such as magnesium stearate, sodium lauryl sulphate and talc may be used at the same time for the tabletting process. In the case of aqueous suspensions the active substances may be combined with various flavour enhancers or colourings in addition to the excipients mentioned above.
It is also preferred if the compounds of formula 1 are administered by inhalation, particularly preferably if they are administered once or twice a day. For this purpose, the compounds of formula 1 have to be made available in forms suitable for inhalation. Inhalable preparations include inhalable powders, propellant-containing metered-dose aerosols or propellant-free inhalable solutions, which are optionally present in admixture with conventional physiologically acceptable excipients.
Within the scope of the present invention, the term propellant-free inhalable solutions also includes concentrates or sterile ready-to-use inhalable solutions. The preparations which may be used according to the invention are described in more detail in the next part of the specification.
Inhalable Powders
If the active substances of formula 1 are present in admixture with physiologically acceptable excipients, the following physiologically acceptable excipients may be used to prepare the inhalable powders according to the invention: monosaccharides (e.g. glucose or arabinose), disaccharides (e.g. lactose, saccharose, maltose), oligo- and polysaccharides (e.g. dextran), polyalcohols (e.g. sorbitol, mannitol, xylitol), salts (e.g. sodium chloride, calcium carbonate) or mixtures of these excipients with one another. Preferably, mono- or disaccharides are used, while the use of lactose or glucose is preferred, particularly, but not exclusively, in the form of their hydrates. For the purposes of the invention, lactose is the particularly preferred excipient, while lactose monohydrate is most particularly preferred. Methods of preparing the inhalable powders according to the invention by grinding and micronising and by finally mixing the components together are known from the prior art.
Propellant-Containing Inhalable Aerosols
The propellant-containing inhalable aerosols which may be used according to the invention may contain the compounds of formula 1 dissolved in the propellant gas or in dispersed form. The propellant gases which may be used to prepare the inhalation aerosols according to the invention are known from the prior art. Suitable propellant gases are selected from among hydrocarbons such as n-propane, n-butane or isobutane and halohydrocarbons such as preferably fluorinated derivatives of methane, ethane, propane, butane, cyclopropane or cyclobutane. The propellant gases mentioned above may be used on their own or in mixtures thereof. Particularly preferred propellant gases are fluorinated alkane derivatives selected from TG134a (1,1,1,2-tetrafluoroethane), TG227 (1,1,1,2,3,3,3-heptafluoropropane) and mixtures thereof. The propellant-driven inhalation aerosols used within the scope of the use according to the invention may also contain other ingredients such as co-solvents, stabilisers, surfactants, antioxidants, lubricants and pH adjusters. All these ingredients are known in the art.
Propellant-Free Inhalable Solutions
The compounds of formula 1 according to the invention are preferably used to prepare propellant-free inhalable solutions and inhalable suspensions. Solvents used for this purpose include aqueous or alcoholic, preferably ethanolic solutions. The solvent may be water on its own or a mixture of water and ethanol. The solutions or suspensions are adjusted to a pH of 2 to 7, preferably 2 to 5, using suitable acids. The pH may be adjusted using acids selected from inorganic or organic acids. Examples of particularly suitable inorganic acids include hydrochloric acid, hydrobromic acid, nitric acid, sulphuric acid and/or phosphoric acid. Examples of particularly suitable organic acids include ascorbic acid, citric acid, malic acid, tartaric acid, maleic acid, succinic acid, fumaric acid, acetic acid, formic acid and/or propionic acid etc. Preferred inorganic acids are hydrochloric and sulphuric acids. It is also possible to use the acids which have already formed an acid addition salt with one of the active substances. Of the organic acids, ascorbic acid, fumaric acid and citric acid are preferred. If desired, mixtures of the above acids may also be used, particularly in the case of acids which have other properties in addition to their acidifying qualities, e.g. as flavourings, antioxidants or complexing agents, such as citric acid or ascorbic acid, for example. According to the invention, it is particularly preferred to use hydrochloric acid to adjust the pH.
Co-solvents and/or other excipients may be added to the propellant-free inhalable solutions used for the purpose according to the invention. Preferred co-solvents are those which contain hydroxyl groups or other polar groups, e.g. alcohols—particularly isopropyl alcohol, glycols—particularly propyleneglycol, polyethyleneglycol, polypropyleneglycol, glycolether, glycerol, polyoxyethylene alcohols and polyoxyethylene fatty acid esters. The terms excipients and additives in this context denote any pharmacologically acceptable substance which is not an active substance but which can be formulated with the active substance or substances in the pharmacologically suitable solvent in order to improve the qualitative properties of the active substance formulation. Preferably, these substances have no pharmacological effect or, in connection with the desired therapy, no appreciable or at least no undesirable pharmacological effect. The excipients and additives include, for example, surfactants such as soya lecithin, oleic acid, sorbitan esters, such as polysorbates, polyvinylpyrrolidone, other stabilisers, complexing agents, antioxidants and/or preservatives which guarantee or prolong the shelf life of the finished pharmaceutical formulation, flavourings, vitamins and/or other additives known in the art. The additives also include pharmacologically acceptable salts such as sodium chloride as isotonic agents. The preferred excipients include antioxidants such as ascorbic acid, for example, provided that it has not already been used to adjust the pH, vitamin A, vitamin E, tocopherols and similar vitamins or provitamins occurring in the human body. Preservatives may be used to protect the formulation from contamination with pathogens. Suitable preservatives are those which are known in the art, particularly cetyl pyridinium chloride, benzalkonium chloride or benzoic acid or benzoates such as sodium benzoate in the concentration known from the prior art.
For the treatment forms described above, ready-to-use packs of a medicament for the treatment of respiratory complaints are provided, containing an enclosed description including for example the words respiratory disease, COPD or asthma, together with a naphthyridine according to formula 1 and one or more combination partners selected from those described above.
