IRAK4 plays a key role in the activation of the immune system, in particular in innate immunity.
Innate immunity is based on the fact that microorganisms such as bacteria and viruses have certain inherent features which are recognized by the immune system, resulting in its activation. What is recognized are certain pathogen-associated molecular patterns (PAMPs). PAMPs are recognized by the pattern recognition receptors (PRR) which include toll-like receptors (TLR) (Janeway and Medzhitov, Annu. Rev. Immunol., 2002). In humans, ten different TLRs have been described.
TLR1 and TLR6 are coreceptors for TLR2. TLR2 recognize inter alia lipoproteins and lipopeptides. TLR3 recognizes double-stranded RNA. TLR4 recognizes inter alia LPS (lipopolysaccharides) of gram-negative bacteria and lipoteichoic acid of gram-positive bacteria.
TLR5 recognizes flagellin. CpG motives in bacterial DNA are recognized by TLR9 (Miggin, O'Neill, J. Leukoc. Biol., 2006). Additional molecules may further modify the recognition ies of TLRs (Akashi-Takamura and Miyake, Current n in Immunology, 2008). In addition to the recognition of PAMPs, TLRs are also able to ize DAMPs (damage-associated molecular n). These are nous cell-derived molecules formed as the result of a trauma, an ischaemia or other tissue-destroying processes in the absence of any obvious infection. DAMPs can be constituents both of the cytoplasm and the s. They are secreted, for example HMGB1 (high-mobility group box 1 n), which is ized by TLR2 and TLR4. Other DAMPs are released de novo or accumulate, for example, in the outer plasma membrane, e.g. HSP90 (heat shock protein 90), where they are recognized by TLR2 and TLR4. Others for their part are produced as final degradation products during cell death (Krysko, Garg, et al., Nat Rev Cancer, 2012).
In addition to TLRs, other components such as cytokines also play an important role in innate immunity. Here, mention may be made in particular of the interleukin (IL)-1 family including interleukins IL-1, IL-18 and IL-33. They are produced and released by various immune cells in the presence of infections or cell or tissue stress. The immune response is then triggered by binding to the respective receptor (Dinarello, Annu. Rev. Immunol., 2009).
TLRs t for TLR3) as well as the receptors of the IL-1 family (IL-1R (receptor), IL-18R and IL-33R) have the same signal e which is activated by binding of the respective ligand to its or. The ligand receptor binding leads to the recruitment of the adaptor molecule MyD88 [myeloid differentiation primary response gene (88)] to the receptor Via TIR/TIR demain interaction which is a constituent both of the receptors and of MyD88. In addition to the TIR domain, MyD88 has an N-terminal "death domain" (DD) which interacts with the DD domain of the interleukin—1 or associated kinase-4 (IRAK4). IRAK4 belongs to a serine/threonine kinase family which also includes the structurally similar kinases IRAKl, [RAKZ and IRAK-M (Cao et al., e, 1996; Muzio et al., Science, 1997; Wesehe, Gao, et al., Journal of Biological Chemistry, 1999; Li, Strelow, et al., PNAS, 2002). Except for IRAK«M, which is only expressed in monocytes and macrophages, the expression of IRAK4, IRAKl and IRAKZ is ubiquitous (Flannery and Bowie, Biochemical Pharmacology, 2010). As a result of the activation process, several MyD88 and IRAK4 molecules form a multicomplex which is referred to as “myddosome” (Precious et al., J. Biol. Chem.. 2009). This myddosome now interacts with IRAKI or IRAK2 via DD-DD interactions. forming a larger complex in the process (Lin, Lo, et al., Nature. 2010). The formation of this complex then triggers autophosphorylation of IRAK4, which subsequently results in the phosphorylation of IRAKI or [RAKl As a consequence of the activation of IRAKI or IRAKZ, these kinases are autophosphorylated (Kollewe, Mackensen, et al., l of Biological Chemistry, 2004). The activated lRAKl or IRAK2 interacts with TRAF6 (tumor—necrosis factor— receptor-associated factor 6) which, with the uhiquitin enzyme complex (E2), acts as ubiquitin protein ligase, which leads to K62-associated ubiquitination of TRAF6. In turn, this process leads to fiirther complex formation with other proteins. This complex induces the activation of TAKl (Xia, Sun, et al., , 2009). ted TAKl mediates the activation of the NF (nuclear factor)- kB signal pathway and the MAPK (mitogen-activated protein kinase) signal pathway (Wang, Deng, et al., Nature, 2001). In the first signal pathway, TAKl leads to the activation of the [KK complex whereby the inhibiting IkB protein is phosphorylated and ed by the proteasome. NF-kB, which had been blocked by IkB beforehand, now migrates from the cytoplasm into the nucleus Where it binds to a specific DNA motive, the kB motive, leading to the transcription of various genes (Gasparini and Feldmann, Curr Pharm Des, 2012).
In the MAPK signal pathway, TAKl phosphorylates various members of the MAPK family such as MK3, -4, -6 and -7 (Wang, Deng, et al., Nature, 2001). The activation of these kinases results in the activation of p38 and JNK (c-Jun inal kinase) (Ono and Han, Cellular Signalling, 2000; Davis, Cell, 2000), The activation both of the NF-kB signal pathway and of the MAPK signal y leads to various processes associated with different immune processes. Thus, this is an increased expression of various inflammatory signal molecules and enzymes such as, for e, cytokines, chemokines and COX-2, and an increased mRNA stability of certain genes (Holtmann, Enninga, et al., Journal of ical Chemistry, 2001; Datta, Novotny, et al., The Journal of Immunology, 2004). Furthermore, these processes may be ated with the proliferation and differentiation of certain cell types (Wan, Chi, et al., Nat Immunol, 2006; McGettrick and J. l, h Journal of Haematology, 2007).
The central importance of IRAK4 in immunological processes mediated by the TLR (except for TLR3) and IL—1 receptor family is shown by the deletion of IRAK4. Cells isolated from patients where absence of 1RAK4 had been trated show no activity after stimulation of various TLRs (except for TLR3) and the IL-ll3 family (Davidson, Currie, et al., The Journal of Immunology, 2006; Ku, von Bemuth, ct a1., IBM, 2007). Furthermore, mice with IRAK4 deletion p no response to IL—IB stimulation and s TLR stimulations except for TLR3 i, Suzuki, et al., Nature, 2002). Here, in particular the kinase activity of [RAK4 plays a crucial role (Kim, Staschke, et a1., IBM, 2007). In contrast, deletion of IRAKI or IRAK2 only results in a signal pathway activity loss after ation (Thomas, Allen, et al., The Journal of Immunology, 1999; Swantek, Tsen, et al., The Journal of Immunology, 2000; Kawagoe, Sato, et al., Nat Immunol. 2008). For their part, mice having deletion of IRAK2 and IRAKl show a phenotype comparable to that of animlas with IRAK4 deletion (Kawagoe. Sato. et al.. Nat l. 2003).
The l role of [RAH-1 in the pathology of various inflammatory ers associated with the p... {1! signal pathway described had already been shown by direct ison of ype (WT) mice with genetically modified animals having a kinase-inactivated form of M4 (IRAK4 KDKJ).
IRAK4 KDKI animals have an improved clinical picture in the animal model of multiple sclerosis, atherosclerosis, myocardial infarction and Alzheimer‘s disease (Rekhter, Staschke, et a1., mical and BiOphysical Research Communication, 2008; a, Mizue, et a1., Circulation, 2009; Staschke, Dong, et al., The Journal of Immunology, 2009; Kim, Febbraio, et al., The Journal of Immunology, 2011; Cameron, Tse, et al., The Journal of Neuroscience, 2012).
Furthermore, it was found that deletion of IRAK4 in the animal model protects against virus— induced myocarditis by virtue of an improved anti—viral reaction with simultaneously reduced systemic inflammation (Valaperti, Nishii, et a1., Circulation, 2013).
Owing to the central role of IRAK4 in the MyD88—mediated signal cascade of TLRs (except for TLR3) and the IL-1 receptor family, the inhibition of IRAK4 can be ed for the prophylaxis and/or treatment of ers mediated by the receptors mentioned. TLR-dependent processes are ated with a large number of different disorders. Thus, it has been found that TLRs are involved in the pathogenesis of multiple sclerosis, rheumatoid arthritis, metabolic syndrome, diabetes, osteoarthritis, Sjogren syndrome and sepsis (Scanzello, Plaas, et a1. Curr Opin Rheumatol, 2008; Roger, vaux, et al, PNAS, 2009; Gambuzza, Licata, et al., Journal of Neuroimmunology, 2011; Fresno, Archives Of Physiology And Biochemistry, 2011; Goh and Midwood, Rheumatology, 2012; Dasu, Ramirez, et a1., Clinical Science, 2012; Ramirez and Dasu, Curr Diabetes Rev, 2012; Li, Wang, et a1., Pharmacology & Therapeutics, 2013). Skin disorders such as psoriasis, at0pic dermatitis, acne inversa and acne vulgaris are associated with the IRAK4- mediated TLR signal pathway.
The disorders mentioned are characterized by an increased expression of certain TLR3, and their pathological immune reactions are ed by certain TLR-associated ation processes (Gilliet, Conrad, et a1., Archives of Dermatology, 2004; r, Langnickel, et a1., Allergy, 2008; Miller, Adv Dermatol, 2008; Terhorst, Kalali, et a1., Am J Clin Dermatol, 2010; za, Wolpert, et al., J Invest Dermatol, 2012; Selway, Kurczab, et a1., BMC Dermatology, 2013; a, Koch, et a1. Indian Dermatol Online, 2013).
Pulmonary disorders such as pulmonary fibrosis, obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), acute lung injury (ALI), interstitial lung disease (ILD), sarcoidosis and pulmonary hypertension show an ation with various TLR-mediated signal ys. The pathogenesis of the pulmonary disorders may be either infectiously mediated or non-infectiously mediated processes (Ramirez Cruz, Maldonado Bernal, et a1., Rev Alerg Mex, 2004; Jeyaseelan. Chu. et al., Infection and Immunity, 2005: Seki, Tasaka. et a1., Inflammation Research. 2010: Xiang. Fan. et a1., Mediators of Inflammation, 2010: Margaritopoulos. Antonjou, ct a1., Fibrogencsis 8.: Tissue Repair, 2010: Hilberath, Carlo, et al., The FASEB Journal, 2011; Nadigel. tainc. et 31.. Respiratory Research. 2011; Kovach and ford. International Immunophannacology. 2011; Bauer, Shapiro, et a1., Mol Med, 2012; Deng, Yang, et al., PLOS One, 2013; Freeman, Martinez, et a1., Respiratory Research, 2013; Dubaniewicz, A., Human Immunology, 2013). For instance, HMGBI (high-mobility group box 1 protein) - an endogenous ligand of TLR2 and TLR4 - is elevated in patients with pulmonary fibrosis, Blocking of these TLR signal pathways leads to reduced inflammation in the animal model (Yang, Cui, et al, The Journal of Immunology, 2009; Entezari, Weiss, at 211., Mol Med, 2012). The involvement of TLR2— mediated processes in the pathogenesis of sarcoidosis has recently been demonstated in in vitro and in vivo s (Chen, Song, et a1., American l of Respiratory and Critical Care Medicine, 2010; Gabrilovich, h, et al., Clinical & Experimental Immunology, 2013).
TLRS are also involved in the pathogenesis of other inflammatory ers such as Behcet's disease, gout and graft rejection, ore, here the inhibition of IRAK4 is a suitable therapeutic ch (Iriu-Bryan, Scott, et a1., Arthritis & Rheumatism, 2005; Shi, Mucsi, et a1., Immunological Reviews, 2010; Leventhal and Schroppel, Kidney Int, 2012; Kreisel and Goldstein, Transplant ational, 2013; Li, Wang, et a1., Pharmacology & Therapeutics, 2013). Lesions and peritoneal macrophages of endometriosis ts also have, compared to healthy volunteers, an enhanced immune response ing LPS (lipopolysaccharide) stimulation (Allhorn, Boing, et a1., Reproductive Biology and Endocrinology, 2008; Khan, Kitajima, et a1., Journal of Obstetrics and Gynaecology Research, 2013).
Patients having lupus erythematosus and adult onset Still disease have an elevated expression of TLR7, MyD88 and 1RAK4 (Chen, Lin, et a1., Arthritis Res Ther, 2013). In the disease model of lupus, inhibition of TLR7, 8 and 9 and the use of animals having a deletion of TLR7 and/or TLR9 result in an improved pathogenesis (Christensen, Shupe, et a1., Immunity, 2006; Nickerson, Christensen, et al., The Journal of Immunology, 2010; Zhu, Jiang, et a1., Autoimmunity, 2013).
Patients suffering from chronic inflammatory bowel diseases such as ulcerative colitis or Crohn's disease do not only have polymorphisms in various TLR genes. In various s models, it was shown that certain TLRs are also involved in the pathogenesis of these bowel disorders (Rakoff- Nahoum, Hao, et al., Immunity, 2006; Heimesaat, Fischer, et al., PLoS ONE, 2007; Cairo, Inflammatory Bowel Diseases, 2010; Walsh, Carthy, et al., Cytokine & Growth Factor Reviews, 2013).
In addition to the disorders already mentioned, IRAK4—mediated TLR processes have been bed in the pathogenesis of eye disorders such as keratitis, allergic conjunctivitis, conjunctivitis sicca, macular degeneration and uveitis (Kaamiranta and Salminen, J Mol Med (Berl), 2009; Sun and Pearlman, Investigative Ophthalmology & Visual Science, 2009; Redfern and McDermott, Experimental Eye Research, 2010; Kezic, Taylor, et al., J Leukoc Biol, 2011: Chang, McCluskey. et al., Clinical & Experimental Ophthalmology, 2012; Guo. Gao, et al., lmmunol Cell Biol. 2012: Lee. Hattori. et al., igative Ophthalmology & Visual Science. 2012).
The role of TLRs in aneriosclerosis has been supported not only by the is of human samples but also with the aid of various animal models (Seneviratne, Sivagurunathan, et al., Clinica Chimica Aeta, 2012; Falck-Hansen, eridi, et al., International Journal of Molecular Sciences, 2013).
By virtue of the central role of IRAK4 in TLR-mediated processes, the inhibition of IRAK4 allows the treatment and/or prevention of vascular and neurological disorders such as, for example, myocardial reperfusion , myocardial infarction, hypertension (Oyarna, Blais, et al., Circulation, 2004; Timmers, Sluijter, et al., Circulation Research, 2008, Fang and Hu, Med Sci Monit, 2011; Bijani, International Reviews of Immunology, 2012; Bomfim, Dos Santos, et al., Clin Sci (Lond), 2012; Christia and Frangogiannis, European Journal of Clinical Investigation, 2013; Thompson and Webb, Clin Sci (Lond), 2013) and also Alzheimer‘s disease, stroke and Parkinson's disease (Carty and Bowie, Biochemical Pharmacology, 2011; Lim, Kou, et al., The American Journal of Pathology, 201 1; Béraud and Maguire—Zeiss, Parkinsonism & Related Disorders, 2012; Noelker, More], et al., Sci. Rep, 2013; Wang, Wang, eta1., Stroke, 2013). es as well as lia and astrocytes express a large part of the known TLRs.
In the animal model, on ofTLR? protects against various triggers of pruritus (Nicotra, Loram, et al., Experimental Neurology, 2012; Liu and Ji, Pflugers Arch, 2013). In addition to the role of TLRs in pruritus, it was possible to demonstrate involvement in pain processes using various animal models (Kim, Lee, et al., Toll-like ors: Roles in Infection and thology, 2009; Guerrero, Cunha, et al., European Journal of Pharmacology, 2012; Nicotra, Loram, et al., Experimental Neurology, 2012; David, Ratnayake, et al., Neurobiology of Disease, 2013). s with pain patients support these findings (Kwok, nson, et al., PLoS ONE, 2012; Chopra and Cooper, J Neuroimmune Pharmacol, 2013).
Since the TLR signals are mediated via IRAK4, it has to be assumed that there is a therapeutic effect by inhibition of IRAK4 in the indications mentioned.
This also applies to some oncological disorders. Certain lymphomas have an activating MyD88 mutation which can be treated using an IRAK4 inhibitor (Ngo, Young, et al., Nature, 2011; Treon, Xu, et al., New England Journal of Medicine, 2012; Choi, Kim, et al., Human ogy, 2013).
Chronic lymphatic leukaemia, melanomas and liver cell carcinomas are likewise associated with mutations in MyD88 or changes in MyDSS activity (Puente, Pinyol, et al., , 2011; Srivastava, Geng, et al., Cancer Research, 2012; Liang, Chen, et al., Clinical Cancer Research, 2013). Furthermore, MyD88 plays an important role in pendent tumours, so TRAK4 inhibitors are also suitable for treating these (Kfoury. A.. K. L. Corf. et al.. Journal of the National Cancer Institute. 2013).
In addition to the mediation of MyDSS- and TLR- (except for TLR3)-associated ses. [RAK4 also mediates the signals of the lL-l receptor family. Inflammatory disorders such as CAPS (cryopyrin-associated periodic syndromes) ing FCAS (familial cold autoinflammatory syndrome), MWS (Muckle-Wells syndrome), NOMID (neonatal-onset multisystem inflammatory disease) and CONCA ic infantile, neurological, ous, and articular) syndrome; FMF (familial mediterranean fever), HIDS (hyper-lgD syndrome), TRAPS (tumour necrosis factor receptor l-associated periodic syndrom), juvenile idiopathic arthritis, adult-onset Still’s disease, Adamantiades-Behcet's disease, rheumatoid arthritis, osteoarthritis, keratoconjunctivitis sicca and n syndrome are treated by blocking the IL—1 signal pathway; therefore here, too, an IRAK4 inhibitor is suitable for treatment of the diseases mentioned (Narayanan, es, et al., Cornea, 2008; Henderson and Goldbach—Mansky, Clinical Immunology, 2010; Dinarello, European Journal of Immunology, 2011; Gul, Tugal—Tutkun, et al., Ann Rheum Dis, 2012; Pettersson, Annals of MedicinePetterson, 2012; Ruperto, Brunner, et al., New England Journal of Medicine, 2012; Nordstrom, Knight, et al., The Journal of Rheumatology, 2012; Vijmasi, Chen, et al., M01 Vis, 2013; Yamada, Arakaki, et al., Opinion on eutic Targets, 2013). IL—18 in particular is associated with the pathogenesis of rheumatoid arthritis, adult-onset Still's disease, type-1 diabetes, multiple sclerosis and lupus erythematosus, thus, by virtue of the mechanism of action, IRAK4 inhibitors can be ed for the treatment and/or prevention of the disorders mentioned (Volin and Koch, J eron Cytokine Res, 201 l; i, Hagglof, et al., Cell M01 Life Sci, 2013; Yap and Lai, Nephrology, 2013). rmore, IRAK4 inhibitors are suitable for the ent of type-2 diabetes and the sequelae of a myocardial infarction as there are indications that the inhibition of the IL-1 signal pathway is a promising therapeutic approach (Abbate, Kontos, et al., The American Journal of Cardiology, 2010; Akash, Shen, et al., Journal of ceutical Sciences, 2012; Abbate, Van Tassell, ct al., The American Journal of logy, 2013). Several components of the IL-1 receptor family are associated with various pulmonary disorders such as asthma, COPD, idiopathic interstitial pneumonia and acute respiratory distress syndrome (ARDS) and the role in its pathogenesis was supported in various animal models (Kang, Homer, et al., The Journal of Immunology, 2007; Imaoka, Hoshino, et al., European Respiratory Journal, 2008; Couillin, Vasseur, et al., The Journal of Immunology, 2009; Lloyd, Current Opinion in Immunology, 2010; Pauwels, Bracke, et al., European Respiratory Journal, 2011; Yin, Li, et al., Clinical & mental Immunology, 2012; Alexander-Brett, et al., The Journal of al Investigation, 2013; Bunting, , et al., BioMed Research International, 2013; Byers, Alexander-Brett, et al., The Journal of Clinical Investigation, 2013; Kawayama, Okamoto, et al., J Interferon Cytokine Res, 2013; ez~Gonzalez, Roca, et al., American Journal of Respiratory Cell and Molecular Biology, 2013; Qiu, Li, et al., logy, 2013).
Furthermore. various studies have shovm that there is a relation between the amount of lL-iB and its receptor. IL—IS and 11:33, and the disorder endomriosis (Altman. Lawson. et al.. Human Reproduction, 2007: Lawson, Bourcier, et al., Journal of Reproductive Immunology, 2003; Sikora, Mieiczarek—Palacz. et al., American l of Reproductive Immunology: Santulli, Borghese. et al., Human Reproduction, 2013). Moreover, in the animal model the growth of human endometrial tissue could be blocked by stration of the endogenous IL-IB inhibitor IL-1R2 (Khoufache, Bondza, et al., The American Journal of Pathology, 2012). By way of its mechanism of action, an IRAK4 inhibitor is also effective in this case. Chronic inflammatory bowel diseases such as Crohn's disease and ulcerative colitis are associated with the dysregulation of the IL-1 receptor family (Kobori, Yagi, et al., J Gastroenterol, 2010; Hao, Liu, et al., Curr Opin Gastroenterol, 2013).
In addition to the indications mentioned, IRAK4 inhibitors are also le for the treatment and/or prevention of ogical disorders mediated by the IL-1 receptor family, such as stroke apoplexy, Alzheimer's disease, stroke, skull-brain trauma and pain such as cancer pain, postOperative pain, inflammation—induced pain and chronic pain (Wolf, Livshits, et al., Brain, Behavior, and Immunity, 2008; Brough, Tyrrell, et al., Trends in Pharmacological, 2011; SciencesDenes, Kitazawa, Cheng, et al., The Journal of Immunology, 2011; Pinteaux, et al., Cerebrovascular Diseases, 2011; del Rey, Apkarian, ct al., Armals of the New York Academy of Sciences, 2012; Denes, son, ct al., Disease Models & Mechanisms, 2013; Han, Zhao, et al., Neuroscience, 2013; Zhao, Zhang, ct al., Neuroscience, 2013). Owing to the propagation of processes mediated by the [U receptor family by IRAK4, IRAK4 inhibitors are active in dermatological ers such as psoriasis, atopic itis and allergic contact dermatitis. The ILI receptor family is ed in the enesis of the disorders mentioned er, Guigue, et al., Annals of Internal Medicine, 2010; Cevikbas, Steinhoff, J Invest ol, 2012; Minkis, Aksentijevich, et al., Archives of Dermatology, 2012; , Ayala, et al., Experimental Dermatology, 2013; Sedimbi, Hagglof, et al., Cell M01 Life Sci, 2013).
Association of IRAK4 with numerous different disorders by mediation of various signals via TLRs (except for TLR3) and the 1L1 receptor family shows that by inhibition of IRAK4 it is possible to influence a large number of disorders in a positive manner.
The compounds described in the present invention are capable of inhibiting IRAK4. This is also ted by the fact that the compounds according to the invention have inhibiting ty in TLR- and IL} -tnediated processes.
Accordingly, it was an object of the t invention to e novel compounds which, in the manner described above, act as inhibitors of interleukin—1 receptor associated kinase—4 ).
The novel 1RAK4 inhibitors are suitable in panicular for the ent and for the prevention of proliferative and inflammatory disorders characterized by an overreacting immune system. ular mention may be made here of inflammatory skin disorders, cardimascular disorders. pulmonary disorders, eye disorders, autoimmune disorders and neoplastic disorders.

If, in the synthesis intermediates and working examples of the ion bed below, a compound is given in the form of a salt of the corresponding base or acid, the exact stoichiometric composition of such a salt as obtained by the reSpective preparation and/or ation process is generally not known. Unless specified in more detail, ons to names and structural formulae, such as "hydrochloride", "trifluoroacetate", "sodium salt" or "X HCl”, "x CF3COOH", "x Na+" are not to be understood stoichiometrically in the case of such salts, but have only descriptive character with regard to the salt-forming components comprised therein.
This applies correspondingly if synthesis intermediates or working examples or salts thereof were obtained by the preparation and/or purification processes described in the form of es, for IO example hydrates, ofunknown stoichiometric composition (if of a defined type).
Compounds according to the invention are the compounds of the formula (I) and their salts, solvates and solvates of the salts. the compounds encompassed by formula (I) of the formulae mentioned below and their salts, solvatcs and solvatcs of the salts and the compounds encompassed by a (I) and ned below as working examples. and their salts. solvates and solvates of the salts, if the compounds encompassed by formula (I) and mentioned below are not already salts, solvates and solvates of the salts.
Preferred salts in the context of the present invention are physiologically acceptable salts of the compounds according to the invention. The invention also encompasses salts which themselves are able for ceutical applications but which can be used, for example, for the isolation or purification of the inventive compounds.
Physiologically acceptable salts of the compounds according to the invention include acid on salts of mineral acids, carboxylic acids and sulphonic acids, for example salts of hydrochloric acid, hydrobromie acid, sulphuric acid, phosphoric acid, methanesulphonic acid, ethanesulphonic acid, toluenesulphonic acid, benzenesulphonic acid, naphthalenedisulphonic acid, acetic acid, trifluoroacetic acid, propionic acid, lactic acid, tartaric acid, malic acid, citric acid, c acid, maleic acid and benzoic acid.
Physiologically acceptable salts of the compounds according to the invention also include salts of conventional bases, by way of example and with preference alkali metal salts (eg. sodium and 3O potassium salts), ne earth metal salts (e.g. calcium and magnesium salts) and ammonium salts derived from ammonia or organic amines having 1 to 16 carbon atoms, by way of example and with preference ethylamine, diethylarnine, triethylaminc, iisopropylamine, monoethanolamine, diethanolamine, anolamine, dicyclohexylamine, ylaminoethanol, procaine, dibenzylamine, ylmorpholine, arginine, lysine, ethylenediamine and N- methylpiperidine.

PCT/EP20l4/O77877 The compounds according to the invention may, depending on their structure, exist in different stereoisomeric forms, i.e. in the form of configurational isomers or else optionally as mational isomers iomers and/or diastcreomers, including those in the case of atropisomers). The present invention therefore encompasses the enantiomers and diastereomers, and the respective mixtures thereof. The stereoisomerically homogeneous tuents can be isolated from such mixtures of omers and/or diastereomers in a known manner; chromatography processes are preferably used for this purpose, eSpecially HPLC tography on an achiral 0r chiral phase.
Where the compounds according to the invention can occur in tautomeric forms, the t invention encompasses all the tautomeric forms.
The present invention also encompasses all suitable isotopic variants of the compounds according to the invention. An isotopic variant of a compound according to the invention is understood here as naming a compound in which at least one atom within the compound according to the invention has been exchanged for another atom of the same atomic number, but with a different atomic mass than the atomic mass which usually or predominantly occurs in nature. Examples of isotopes which can be incorporated into a compound according to the invention are those of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur, fluorine, chlorine, bromine and iodine, such as 2H (deuterium), 3H (tritium), 13C, 14C, 15N, 170, 180, 32F, 33F, 338, 348, 353, 363, 18F, 36Cl, SZBr, 1231, 1241, 1291 and 1311. Particular isotopic ts of a compound according to the invention, especially those in which one or more radioactive isotopes have been orated, may be beneficial, for example, for the examination of the mechanism of action or of the active compound distribution in. the body; due to comparatively easy preparability and detectability, especially compounds ed with 3H or 14C es are suitable for this purpose. In addition, the incorporation of isotopes, for example of deuterium, can lead to particular therapeutic benefits as a consequence of greater lic stability of the compound, for example to an extension of the half—life in the body or to a reduction in the active dose required; such modifications of the compounds according to the invention may therefore in some cases also constitute a preferred embodiment of the present invention. Isotopic variants of the compounds according to the invention can be prepared by the processes known to those skilled in the art, for example by the s described further below and the procedures bed in the working examples, by using corresponding isotopic modifications of the tive reagents and/or starting compounds.

The present invention r provides medicaments which comprise at least one compound according to the invention, typically together with one or more inert, nontoxic, pharmaceutically le excipients, and the use thereof for the aforementioned purposes.
The compounds ing to the invention can act systemically and/or locally. For this e, they can be administered in a suitable manner, for example by the oral, parenteral, pulmonal, nasal, gual, lingual. buccal. rectal. dermal. transdermal, conjunctiva] or otic route, or as an implant 01' stem.
The compounds according to the invention can be administered in suitable stration forms for these administration routes.
Suitable administration forms for oral administration are those which work according to the prior art and release the compounds according to the invention rapidly and/or in a modified manner and which contain the compounds according to the invention in crystalline and/or amorphized and/or ved form, for example tablets (uncoated or coated tablets, for example with gastric juice- resistant or retarded-dissolution or insoluble coatings which control the release of the compound ing to the invention), tablets or films/oblates which disintegrate rapidly in the oral cavity, films/lyophilizates, capsules (for example hard or soft gelatin capsules), sugar—coated tablets, granules, pellets, powders, ons, suspensions, aerosols or solutions.
Parenteral administration can be accomplished with avoidance of an absorption step (for example by an enous, intraarterial, intracardiac, intraspinal or intralumbar route) or with inclusion of an absorption (for example by an intramuscular, subcutaneous, intracutaneous, aneous or intraperitoneal route). Suitable administration forms for parenteral administration include injection and on formulations in the form of solutions, suspensions, emulsions, lyophilizatcs or e powders.
For the other administration routes, suitable es are inhalable medicament forms (including powder inhalers, nebulizers), nasal drops, solutions or sprays, s, films/oblates or capsules for lingual, sublingual or buccal administration, suppositories, ear or eye preparations, vaginal capsules, aqueous suspensions (lotions, g mixtures), lipophilic suspensions, ointments, WO 91426 PCT/EP2014/O77877 creams, transdermal therapeutic s (eg. patches), milk, pastes, foams, sprinkling powders, ts or stents.
Preference is given to oral or parenteral administration, especially oral administration.
The compounds ing to the invention can be converted to the administration forms mentioned. This can be accomplished in a manner known per 36 by mixing with inert, non-toxic, pharmaceutically suitable excipients. These excipients include carriers (for example microcrystalline cellulose, lactose, ol), solvents (cg. liquid polyethylene glycols), emulsifiers and dispersing or wetting agents (for example sodium dodecylsulphate, polyoxysorbitan oleate), binders (for e polyvinylpyrrolidone), synthetic and natural polymers (for example n), stabilizers (e.g. antioxidants, for example ic acid), colorants (cg. inorganic pigments. for example iron ) and flavour and/or odour tants. in general. it has been found to be advantageous in the case of parenteral administration to administer amounts of from about 0.001 to 1 mg/kg. preferably about 0.01 to 0.5 rug/kg, of body weight to achieve efToctivc results. In the case of oral administration the dosage is about 0.01 to 100 mg/kg, preferably about 0.01 to 20 mg/kg and most preferably 0.1 to 10 mg/kg ofbody weight.
It may nevertheless be necessary where appropriate to deviate from the stated amounts, specifically as a function of the body weight, route of administration, individual response to the active compound, nature of the preparation and time or interval over which administration takes place.
Thus, in some cases less than the abovementioned minimum amount may be sufficient, while in other cases the upper limit mentioned must be exceeded. In the case of stration of greater amounts, it may be advisable to divide them into several individual doses over the day.
The working examples which follow illustrate the invention. The invention is not restricted to the examples.
Unless stated otherwise, the percentages in the tests and examples which follow are percentages by weight; parts are parts by weight. Solvent ratios, dilution ratios and concentration data for the liquid/liquid solutions are in each case based on volume.
Preparation of the compounds according to the invention The preparation of the compounds according to the invention is rated by the following synthesis schemes: The ediates 0 shown in Synthesis Scheme 1 can be prepared analogously to ture and patent procedures, for example from 4-substituted 2-fluoronitrobenzaldehydes or 2—chloro-5— nitrobenzaldchydes, or they are commercially available. For the preparation, 4-substituted Z—fluoro— -nitrobenzaldehydes are reacted with hydrazine (J. Med. Chem, 2013, 56, 4343). The resulting 5- nitroindazoles (Intermediates 0) can be reduced, for example, with palladium on carbon by hydrogenation (U8201228984, W020067l940, 153596, EP2045253) or transfer hydrogenation (Eur. J. Med. Chem. 2010. 45. 5520) or by reaction with iron (J. Chem. Soc., 1955. 2412) or tintII) chloride {Bioorg. Med. Chem. 2004. 12. 2115. U3201215962) to give the corresponding S-aminoindazoles. The Intermediates la can be converted into Intermediates 1b. The radical R: can be introduced by various routes, for e via aIkylation with alkyl halides (Bioorg. Med. Chem, 2010, 18, 4801) or alkylsulphonates or via reductive amination by reaction with aldehydes (W02009102498) or ketones (EP140325). le for use as reducing agents are various hyride donors such as, for example, sodium borohydride, sodium cyanoborohydride or sodium trisacetoxyborohydride. Alternatively, it is also possible to e the anilinic nitrogen of the Intermediates la first using an acyl halide or a carboxylic ide, and then to reduce the amide using a suitable reducing agent to give the ponding amine, which also s Intermediates lb. Suitable for use as reducing agents are, for example, lithium aluminium hydride (J. Am. Chem. Soc, 1954, 76, 1384), borane as complex with dimethyl sulphide etic Communications, 1991, 21, 1579) or tetrahydrofuran (Org. and Biomol. Chem, 2012, 10, 8692) or sodium bis(2-methoxyethoxy)aluminium hydride (WO200873461).

Wuts, Theodora W. , 4th Edition (8th er 2006), Wiley—Interscience, Chapter 7), giving the Intermediates 2. The preferred protective group is the tert-butyloxycarbonyl group (BOC protective group). The BOC protective group is ably introduced with di-teIt-butyl dicarbonate in the presence of a base such as, for example, N,N—diisopropylethylamine or triethylamine.
The Intermediates 2 can be reacted with carboxylic esters halogenated in the carboxylic acid moiety such as, for example, methyl bromoacetate, ethyl bromoacetate, tert—butyl bromoacetate, benzyl bromoacetate, ethyl 3-brom0propanoate or ethyl 2-bromopropanoate under basic conditions to give a mixture of the corresponding regioisomeric 1— and 2-a1kylated le compounds (Organic Letters, 2009, 11, 5054; WO200474284; USZOO9286800; WO200919167; W0201297744; J. Med. Chem, 2007, 50, 3101; Molecules, 2006, 11, 86). Here, preference is given to the reaction with N,N—dicyclohexylmethylamine in ydrofuran or N,N- dimethylformamide between 25°C and 100°C (J. Org. Chem. 2006, 71, 5392). Likewise preferred is the reaction in the presence of potassium carbonate in N,N-dimethylformamide. The mixtures of the regioisomeric l— and lated indazole compounds can be separated by column chromatography or preparative HPLC, which gives access to the 2-alkylated indazole compounds (Intermediates 3).
The sion of the Intermediates 3 into the Intermediates 4 can be carried out under known conditions (Protecting Groups, Philip J. Kocienski, 3rd Revised n (9th February 2005), Thieme, Chapter 6; Greene's Protective Groups in Organic Synthesis, Peter G. M. Wuts, Theodora W. Greene, 4th Edition (8th December 2006), Wiley—Interscience, Chapter 5; W02009l9l67 Al).
Here, preference is given to ysis with lithium hydroxide or lithium hydroxide monohydrate in a mixture of tetrahydrofiiran and water (J. Med. Chem.. 2012. 55. 1318, Bioorg. Med. Chem, 2009. 17. 7] l3). Optionally. ethanol or methanol may also be added.
The Intermediates 4 can be reacted with amines to give the corresponding Intermediates 5. Here, use may be made of various coupling rugents known from the literature (Amino Acids. Peptides and Proteins in Organic Chemistry. Vol.3 * ng Blocks, Catalysis and Coupling Chemistry, Andrew B. Hughes, Wiley, Chapter 12 - Peptide-Coupling Reagents, 407—442; Chem. Soc.

Chem. Let., 2008, 18, 2093).
The Intermediates 5 obtained in this manner can be converted into Intermediates 6. The removal of the protective group at the anilinic nitrogen can be carried out under known reaction ions (Protecting Groups, Philip J. Kocienski, 3rd Revised Edition (9th February 2005), Thieme, Chapter 8; 's Protective Groups in Organic Synthesis, Peter G. M. Wuts, ra W.

Using the coupling reagents known from the ture which were already mentioned for the preparation of the Intermediates 5, the Intermediates 6 can be reacted with heterocyclic carboxylic acids to give compounds of the general formula (I). Here, too, preference is given to using 1—(3- dimethylaminopropyl)ethylcarbodiimide hydrochloride in combination with oxy—1H- benzotriazole hydrate (U82006194801).

Assessment of physiological efficacy The in-vitro ty of the compounds according to the invention can be shown in the following assays: Irak4 kinase assay The Irak4-inhibitory activity of the substances ing to the ion of the present invention was measured in the Irak4 TR-FRET assay (TR—FRET = Time Resolved scence Resonance Energy Transfer) described in the paragraphs that follow.
Recombinant fusion protein from N-terminal GST (glutathione S-transferase) and human Irak4, expressed in baculovirus-infected insect cells (Hi5, BTl~TN-SBl—4, cell line sed from lmitrogcn, catalogue No. 3855-02) and purified via y tography, was used as enzyme.
The substrate used for the kinase reaction was the biotinylated peptide biotin-Alix- KKARFSRFAGSSPSQASFAEPG (C-terminus in amide form) which can be sed, for example, from Biosyntan GmbH n-Buch).
For the assay, 11 different concentrations in the range from 20 uM to 0.073 nM were prepared from a 2 mM solution of the test substance in DMSO. For the assay, 50 111 of the respective solution were pipetted into a black low—volume 384-well microtitre plate (Greiner e, Frickenhausen, Germany), 2 pl of a on of lrak4 in assay buffer [50 mM HEPES pH 7.5, 5 mM MgClZ, 1.0 mM dithiothreitol, 30 uM activated sodium orthovanadate, 0.1 % (w/v) of bovine gamma—globulin (BGG) 0.04% (v/v) nonidet-P40 (Sigma)] were added and the mixture was incubated for 15 min to allow prebinding of the substances to the enzyme prior to the kinase reaction. The kinase reaction was then started by addition of 3 ul of a solution of adenosine triphosphate (ATP, 1.67 mM = final concentration in 5 pl of assay volume: 1 pM) and peptide substrate (0.83 MM = final concentration in 5 ul assay volume: 0.5 uM) in assay buffer, and the resulting mixture was incubated at 22°C for the reaction time of 45 min. The concentration of the Irak4 was adjusted to the respective activity of the enzyme and set such that the assay was carried out in the linear range. Typical concentrations were in the order of about 0.2 nM. The on was stopped by addition of 5 pl of a solution of T detection reagents [0.1 uM streptavidin-XL665 (Cisbio Bioassays; France, catalogue No. 6lOSAXLG) and 1.5 nM anti-phosphoserin antibody [Merck Millipore, "STK Antibody", catalogue No. 35—002] and 0.6 nM LANCE EUaW1024-1abelled anti—mouse-IgG antibody (Perkin- Elmer, product No. AD0077, alternatively it is possible to use a terbium cryptate—labelled anti- mouse—IgG antibody from Cisbio Bioassays) in aqueous EDTA solution (100 mM EDTA, 0.4 % [w/v] bovine serum albumin [BSA] in 25 mM HEPES pH 7.5).
The resulting mixture was incubated at 22°C for l h to allow formation of a complex of the biotinylated orylated substrate and the detection ts. The amount of the phosphorylated substrate was then evaluated by measuring the resonance energy transfer from europium e- labelled anti-mouse-IgG antibody to streptavidin-XL665. To this end, the fluorescence ons at 620 nm and 665 run were measured after excitation at 350 nm in a TR-FRET measuring instrument, for example a Rubystar (BMG Labtechnologies, Offenburg, Germany) or a Viewlux (Perkin-Elmer). The ratio of the emissions at 665 nm and 622 nm was taken as a e of the amount of phosphorylated substrate. The data were normalized (enzyme reaction without test substance = 0% inhibition; all other assay components but no enzyme 2 100% inhibition).
Typically, the test substances were tested on the same microtitre plate at 11 different concentrations in the range from 20 pM to 0.073 nM (20 pM, 5.7 uM, 1.6 uM, 0.47 uM, 0.13 pM, 38 nM, ll nM, 3.1 nM, 0.89 nM, 0.25 nM and 0.073 nM). The dilution series were prepared prior to the assay (2 mM to 7.3 nM in 100% DMSO) by serial dilutions. The [C50 values were calculated using a 4- parameter fit.

As a neutral control, cells were treated with 0.05 ug/ml LPS and 1% DMSO and, as inhibitor l, only once with 1% DMSO.
The plates are centrifuged at 80 g for 30 s and incubated at 37°C, 5% C02 and 95% atmospheric humidity for 17 h. The amount of TNF—a was determined using the TNF-alpha HTRF ion Kit (Cisbio, Cat No. 62TNFPEB/C). To this end, in each case 2 ul of the detection solution consisting of anti—TNF—u—XL665 conjugate and NF—a—cryptate conjugate, dissolved in accordance with the instructions of the manufacturer in the reconstitution , were added for the HTRF (Homogeneous Time-Resolved Fluorescence) test. After the on, the mixture was incubated either at room temperature for 3 h or at 4°C overnight. The signals were then read at 620/665 nm using an HTRF-enabled measuring instrument such as the BMG PheraStar.
The ty of the substances is expressed as the ratio between neutral and inhibitor control in percent. The lC50 values were calculated using a 4-parameter fit.

The control group was treated with the e in which the substance had been dissolved (substance vehicle) and also with the vehicle in which the LPS had been dissolved. 0.2 mg of LPS/kg body weight (Sigma, Cat.
No. 1.4391) (lipopolysaccharides from E. coii 0] 1 l:B4) was administered intraperitoneally (i.p.) to the groups treated with substance, and also to the positive control group. In addition, the positive control group was treated with the substance vehicle described above. The substance was administered orally 8 hours before induction of inflammation by administration of LPS. To examine the effect of the compounds according to the invention on the ation, a final blood sample was taken from the animals after 1.5 hours. The concentration of certain nes in the plasma was determined using the Mouse ammatory 7-Plex Tissue Culture Kit (MSD, Cat.
No. K15012B) in accordance with the instructions of the manufacturer. Fig. 1 shows the amount of TNF-a in the plasma, which is reduced in a dose-dependent manner by administration of Exemplary Compound 64 in comparison with the duced concentration.
In vivo model of IL-lli—mediated inflammation To evaluate the potential efficacy of the compounds according to the invention in IL-lB-mediated disorders, IL—lB was administered i.p. to female Balb/c mice (about 8 weeks old, Charles River Laboratories, Germany) and the effect of the compounds according to the invention on IL—lfi— mediated cytokine secretion was examined. In each case, the group size was 5 animals. The l group was treated with the vehicles used for dissolving the substance and the IL-1 [5. In each case 90 ug of IL—lB /kg body weight (R&D, Cat. No. 40l-ML/CF) were administered i.p to the groups treated with substance and the ve control group. The substance or its vehicle in the ve control group were stered 4 hours before the administration of IL-1 B. The determination. of TNF-a in the plasma after the final removal of blood was carried out 2 heurs afier administration of the IL-lB using the Mouse Prolnflammatory 7-Plex Tissue Culture Kit (MSD, Cat. No. B) in accordance with the instructions of the manufacturer. Administration of IL-lB lead to an elevated TNF-a plasma concentration which was inhibited by treatment with Exemplary Compound 64. This is illustrated by Figure 2.
Oxygen-induced in viva retinopathy (OIR) model It has been shown that oxygen-induced retinopathy is a useful animal model for the study of pathological l angiogenesis. This model is based on the observation that hyperoxia during early postnatal development in the retina causes arrest or delay of the growth of normal retinal blood vessels. When, after a 7-day hyperoxia phase, the animals are returned to nonnoxic room air, this is equivalent to relative hypoxia. The ischaemic situation caused in this manner results in an abnormal neovascularization which has some similarities with pathophysiological neovascularization in eye disorders such as wet AMD elated macular degeneration). In addition, the cularization caused is highly reproducible, quantifiable and an important parameter for examining the e mechanisms and possible treatments for various forms of retinal disorders. This is why this model is suitable for examining the effect of the compounds according to the invention on this pathological process.
To this end, young murine animals of an age of 7 days, for example young C57Bl/6 s, are exposed to a hyperoxic nment (70% oxygen) for 5 days, From day 12 to day 17, the mice are kept under normoxic conditions Norrnoxic means room air with 21% oxygen. During this period, the animals are then ed to groups treated with substance and vehicle group and treated according to the group. The animals are sacrificed on day 17, and the eyes are then removed and fixated in 4% formalin. After washing in phosphate-buffered saline, the retina is excised, a flat preparation thereof is produced and this is stained with isolectin B4 dy (Tual~Chalot, Allinson, et al., J. Vis. Exp, 2013). Quantification of neovasculaiization is d out using a Zeiss ApoTome.
In vivo model of laser-induced choroidal neovascularization This study serves to igate the efficacy of a test substance on reduction of extravasation/oedema formation and/or choroidal neovascularization in the rat model of laser- induced choroidal neovascularization. In the animal model, laser-mediated photocoagulation leads to destruction of Bruch's membrane with concomitant damage to the vessels and inflammation— associated neovascularization. Both processes correspond to the pathomechanism of macular degeneration (Grossniklaus, Kang, Berglin, Prog Retin Eye Res, 2010).
To ine the effect of the compounds ing to the invention, Brown Norway Rats (Charles River Laboratories) are assigned to the appropriate groups (substance and vehicle) and anaesthetized, and 0.5% tropicamide is instilled into the eyes to dilate the pupils. After the animals have been anaesthetized (15 mg/kg xylazine and 80 mg/kg ketamine), choroidal neovascularization is triggered by g six holes into the retina in each eye of each animal using a 532 nm argon laser (lesion size: 50 um — 75 um; laser intensity: 150 mW; duration: 100 ms). The treatment of the animals with the substance according to the invention or the corresponding vehicle is d out either from day 1 or from day 7 up to and including day 23. Angiography is d out on day 21.
To this end, the animals are in each case anaesthetised, the pupils are dilated and 10% sodium scein solution is injected subcutaneously. The angiogram is recorded at most 10 minutes after the injection and assessed by three blinded observers using a score system (0: no ng = no tissue injury, = slight staining = slight tissue , 2: moderate staining = moderate tissue injury, 3: maximum staining = maximum tissue injury). The animals are sacrificed on day 23, after which the eyes are removed and fixated in 4% strength paraformaldehyde solution for one hour at room temperature. After one washing, the retina is carefully peeled off and the -choroidea complex is stained using an FITC isolectin B4 antibody and then applied flat to a microscope slide.
The preparations obtained in this manner are evaluated using a fluorescence microscope (Apotom, Zeiss) at an excitation wavelength of 488 nm. The volume or the area of choroidal neovascularization is calculated by morphometric analysis using Axiovision 4.6 software.
