N-(4-(Azaindazol-6-yl)-phenyl)-sulfonamides and their use as pharmaceuticals
The present invention relates to N-(4-(azaindazol-6-yl)-phenyl)-sulfonamides of the formula I,
wherein Ar, n, X, Z, R1 , R2 and R3 have the meanings indicated below. The compounds of the formula I are valuable pharmacologically active compounds which modulate protein kinase activity, specifically the activity of serum and glucocorticoid regulated kinase (SGK), in particular of serum and glucocorticoid regulated kinase isoform 1 (SGK-1 , SGK1 ), and are suitable for the treatment of diseases in which SGK activity is inappropriate, for example degenerative joint disorders or
inflammatory processes such as osteoarthritis or rheumatism. The invention furthermore relates to processes for the preparation of the compounds of the formula I, their use as pharmaceuticals, and pharmaceutical compositions comprising them.
Due to their physiologic importance, variety, and ubiquity, protein kinases have become one of the most important and widely-studied family of enzymes in biochemical and medical research. Studies have shown that the currently known about 500 different protein kinases are key regulators of many cell functions, including signal transduction, transcriptional regulation, cell motility, growth, differentiation, division and destruction. They act through reversible phosphorylation of the hydroxyl groups of distinct amino acids in proteins. Several oncogenes have been shown to encode protein kinases, suggesting that kinases play a role also in oncogenesis. These processes are highly regulated, often by complex intermeshed pathways where each kinase itself will be regulated by one or more kinases.
Consequently, aberrant or inappropriate protein kinase activity can contribute to the rise of disease states associated with such aberrant kinase activity.
The protein kinase family is typically classified into two main subfamilies, protein tyrosine kinases, which phosphorylate tyrosine residues, and protein serine/threonine kinases (PSTK) which phosphorylate serine and threonine residues. The PSTK subfamily is usually cytoplasmic or associated with the particulate fractions of cells, possibly by anchoring proteins. Aberrant PSTK activity has been implicated or is suspected in a number of pathologies such as rheumatoid arthritis, psoriasis, septic shock, bone loss, many cancers and other proliferative diseases. Accordingly,
PSTKs and their associated signal transduction pathways are important targets for drug design.
Serum and glucocorticoid regulated kinases, also designated as serum/glucocorticoid regulated kinase, serum and glucocorticoid induced kinase, serum and glucocorticoid inducible kinase or serum and glucocorticoid dependent kinase, form a family of PSTKs. Currently three members are known, designated as SGK-1 , SGK-2 and SGK-3. They are also designated as SGKL (SGK-like) and CISK (cytokine-independent survival kinase). At the protein level the three isoforms show a homology of at least 80% in their catalytic domain. SGK-1 was described in 1993 for the first time as an "immediate early gene" in a rat mammary cancer cell line
(Webster, M.K. et al., Immediate-early Transcriptional Regulation and Rapid mRNA Turnover of a Putative Serine/Threonine Protein Kinase, J. Biol. Chem. 1993, 268, 1 1482-1 1485). SGK-1 mRNA is expressed ubiquitously in almost all adult tissues and in several embryonic tissues. SGK-2 is expressed with greatest abundance in epithelial tissues, such as in the kidney, liver, pancreas, and specific areas of the brain, whereas SGK-3 was detected in all tested tissues, especially in the adult heart and spleen (Kobayashi, T. et al., Characterization of the structure and regulation of two novel isoforms of serum and glucocorticoidinduced protein kinase, Biochem. J. 1999, 344, 189-197).
A distinguishing feature of SGK to many other kinases is based on the stringent stimulus-dependent regulation of transcription, cellular localization and enzymatic activation of the molecule (Firestone, G.L. et al., Stimulus-Dependent Regulation of Serum and Glucocorticoid Inducible Protein Kinase (SGK) Transcription, Subcellular Localization and Enzymatic Activity, Cell. Physiol. Biochem. 2003, 13, 1 -12). A variety of stimuli are known which induce and activate SGK-1 . These include mineralocorticoids, gonadotropins, 1 ,25(OH)2D3, p53, osmotic, hypotonic and cellular volume changes, and cytokines such as GM-CSF, TNF-alpha and TGF-beta (reviewed in Lang, F. et al., (Patho)physiological Significance of the Serum- and Glucocorticoid-Inducible Kinase Isoforms, Physiol. Rev. 2006, 86, 1 151 -1 178). In further growth-dependent signaling pathways SGK is induced by serum, insulin and IGF-1 , FSH, Fibroblast and Platelet-derived growth factor, activators of the Erk signaling cascade and TPA (reviewed in Lang, F. et al., Physiol. Rev. 2006, 86, 1 151 -1 178). SGK-1 is also known to be activated in pathological changes such as ischemic brain injury (Imaizumi, K. et al., Differential expression of sgk mRNA, a member of the Ser/Thr protein kinase gene family, in rat brain after CNS injury, Mol. Brain Res. 1994, 26, 189-196), pulmonary fibrosis (Warntges, S. et al., Excessive Transcription of the Human Serum and Glucocorticoid Dependent Kinase hSGK1 in Lung Fibrosis, Cell. Physiol. Biochem. 2002, 12, 135-142) or cardiac fibrosis (Funder, J., Mineralocorticoids and Cardiac Fibrosis: The Decade in Review, Clin. Exp.
Pharmacol. Physiol. 2001 , 28, 1002-1006).
In order to be converted into its functional form, SGK-1 requires activation by phosphorylation. This is mediated by a signaling cascade involving the
phosphatidylinositol 3 (PI-3) kinase and phosphoinositide 3-dependent kinases PDK1 and PDK2. The activation of SGK-1 through the PI-3 kinase signaling pathway is known to be a response to insulin, IGF and growth factors. For activation the phosphorylation of two amino acid residues is necessary, threonine256 on the T-loop (mediated by PDK1 ) and serine422 at the hydrophobic motif of the protein (catalyzed by a putative PDK2) (reviewed in Lang, F. et al., Physiol. Rev. 2006, 86, 1 151 -1 178).
For the function of SGK, there are a series of studies that show regulatory influence of SGK-1 , SGK-2 and SGK-3 on cell membrane channels. It was shown that the epithelial Na+ channel (ENaC), the main transporter for the mineralocorticoid-regulated Na+ reabsorption in the renal tubule, is a target of SGK-1 , SGK-2 and SGK-3 (Faletti, C.J. et al., sgk: an essential convergence point for peptide and steroid hormone regulation of ENaCmediated Na+ transport, Am. J. Physiol. Cell Physiol. 2002, 282, C494-C500; Friedrich, B. et al., The serine/threonine kinases SGK2 and SGK3 are potent stimulators of the epithelial Na+ Channel alpha, beta, gamma-ENaC, Pflugers Arch. - Eur. J. Physiol. 2003, 445, 693-696). The interaction of ENaC and SGK is not by direct phosphorylation, but due to the inactivation of the ubiquitin ligase Nedd4-2 (Debonneville, C. et al., Phosphorylation of Nedd4-2 by Sgk1 regulates epithelial Na+ channel cell surface expression, EMBO J. 2001 , 20, 7052-7059) as a result of phosphorylation by SGK. As a result, the amount and residence time of ENaC in the cell membrane is increased (Staub, O. et al., Regulation of stability and function of the epithelial Na+ channel (ENaC) by ubiquitination, EMBO J. 1997, 16, 6325-6336). It has also been shown that the renal outer medullary potassium channel (ROMK1 ) and the sodium-hydrogen exchanger 3 (NHE3) are indirectly regulated by SGK, via the Na+/H+ exchange regulating factor 2 (NHERF2) as an intermediary molecule (Yun, C.C. et al., Glucocorticoid Activation of Na+/H+ Exchanger Isoform 3 Revisited. The Roles of SGK1 and NHERF2, J. Biol. Chem. 2002, 277, 7676-7683; Yun, C.C, Concerted Roles of SGK1 and the Na+/H+
Exchanger Regulatory Factor 2 (NHERF2) in Regulation of NHE3, Cell. Physiol, Biochem. 2003, 13, 29-40). In addition it has also been shown that SGK influences the Kv1 .3 channel-dependent K+ current (Gamper, N. et al., IGF-1 up-regulates K+ Channels via PI3-kinase, PDK1 and SGK1 , Pflugers Arch. 2002, 443, 625-634) and regulates the amino acid transporter SN1 and 4F2/LAT (Wagner, C.A. et al., The heterodimeric amino acid transporter 4F2hc/LAT1 is associated in Xenopus oocytes with a non-selective cation channel that is regulated by the serine/threonine kinase sgk-1 , J. Physiol. 2000, 526.1 , 35-46; Boehmer, C. et al., Properties and regulation of glutamine transporter SN1 by protein kinases SGK and PKB, Biochem. Biophys. Res. Commun. 2003, 306, 156-162). SGK-1 has also been shown to play a role in cell proliferation and electrolyte homeostasis (Vallon, V. et al., New insights into the role of serum- and glucocorticoid-inducible kinase SGK1 in the regulation of renal function and blood pressure, Curr. Opin. Nephrol. Hypertens. 2005, 14, 59-66; Lang, F. et al., Regulation of Channels by the Serum and Glucocorticoid-linducible Kinase -Implications for Transport, Excitability and Cell Proliferation, Cell. Physiol. Biochem. 2003, 13, 41 -50). SGK-1 is thought to regulate several cellular mechanisms that contribute to disease states. For example, SGK-1 has been shown to mediate fibronectin formation in diabetic nephropathy (Feng, Y. et al., SGK1 -mediated
Fibronectin Formation in Diabetic Nephropathy, Cell. Physiol. Biochem. 2005, 16, 237-244). SGK1 has also been shown to mediate insulin, IGF-1 , and aldosterone-induced Na+ retention in renal and cardiovascular disease (Vallon, V. et al., Curr. Opin. Nephrol. Hypertens. 2005, 14, 59-66; Lang, F. et al., Cell. Physiol. Biochem. 2003, 13, 41 -50). SGK1 has furthermore been shown to be activated by loss of laforin in Lafora disease, a genetic form of myoclonic epilepsy, SGK1 inhibition resulting in a reduction of abnormal glycogen accumulation and offering a way of treating Lafora disease (Singh, P. K. et al., Activation of serum/glucocorticoid-induced kinase 1 (SGK1 ) underlies increased glycogen levels, mTOR activation, and autophagy defects in Lafora disease, Mol. Biol. Cell 2013, 24, 3776-3786).
Osteoarthritis (OA) is one of the most common degenerative joint diseases and leads in an advanced stage to a loss of joint function. During the chronic course of illness, there is a destruction of the articular cartilage down to the underlying bone tissue, which makes a joint replacement surgery in affected patients necessary. In addition to the destruction of the cartilage, pathological changes in the synovial membrane and the ligaments can also be observed. The disease is temporarily accompanied by inflammatory processes like in rheumatoid arthritis, but differs from it. The exact causes of the disease are still unknown, however, several factors come into question, such as metabolic changes, mechanical stress, genetic disorders or joint injuries. Regardless of the original trigger, the degradation of articular cartilage occurs as a common pathological feature of OA. A key feature of the pathological condition of OA is the proteolytic cleavage of collagens and proteoglycans. Simultaneously a number of other processes occur such as anabolic repair mechanisms, ^differentiation of the cells or cell death. The precise molecular mechanisms underlying these processes are still poorly understood.
The healthy functioning of the adult cartilage is created by its unique biomechanical properties, providing both the resistance against high pressure as well as the necessary elasticity of the tissue. The decisive factor is the special organization of the cartilage tissue. Unlike most other tissues, the cartilage cells are not in direct contact but are embedded separately from each other in an extracellular matrix (ECM). The macromolecules of this ECM guarantee the viability of the articular cartilage and joints. The basic structure of the ECM consists of a network that is formed by fibrils of collagen types II, IX and XI. Proteoglycans, mainly aggrecan, are embedded in the ECM producing an extremely high osmotic water binding capacity. The water pressure generated in connection with the properties of the collagen backbone guarantees the specific properties of the cartilage. A main feature of the pathogenesis of OA is the loss of the ECM of the cartilage and the articular cartilage tissue. The function of the affected joint is restricted by or lost by this mechanism. In addition, various symptomatic parameters such as pain appear during symptomatic progression of the disease. Current treatments for osteoarthritis are limited mostly to the alleviation of symptomatic complaints. A causal therapy based on drugs, which leads to the decrease of cartilage degeneration, is not possible to current knowledge. Therefore, there is a considerable need for novel drugs for the prevention and/or therapy of osteoarthritis.
It has been shown, through comparative gene expression analysis of samples of total-cellular RNA from healthy and degenerated/degenerating cartilage that SGK-1 is expressed in degenerated/degenerating osteoarthritic cartilage, while it is not detectable in healthy articular cartilage (Bartnik, E. et al., Use of a
Serum/Glucocorticoid-regulated Kinase, WO 2006/061 130). Moreover, further experiments gave evidence of the causal implication of SGK in the pathogenesis of degenerative cartilage changes (Bartnik, E. et al., WO 2006/061 130). As a
conclusion of these studies, SGK-1 is specifically involved in pathological conditions of the cartilage, for example in the context of rheumatoid arthritis or osteoarthritis, in particular in the context of osteoarthritis, and thus represents a key molecule inducing cartilage degradative processes. Due to the high homology between the SGK family members, it is assumed that this also applies to the SGK-2 and SGK-3.
The identification of these relationships allows the discovery of drugs for the prevention or therapy of degenerative cartilage changes by determining the effect of potential drugs on the activity of SGK and/or the levels of SGK by known test methods. The causal implication of SGK in the pathogenesis of degenerative joint disease allows a focused search for therapeutic agents that target regulatory mechanisms for the restoration of normal cell physiology of cartilage. In the joints of mouse embryos SGK-1 mRNA was detected specifically in hypertrophic
chondrocytes but not in proliferative cells. The role of SGK-1 in this model of skeletal development and endochondral ossification shows that the natural occurrence of SGK-1 in cartilage is not associated with the synthesis and maintenance of cartilage, but exerts its function in the conversion (hypertrophy) and degradation. The expression of SGK-1 in osteoarthritic cartilage is thus a process that causes or promotes the pathology of OA. Due to its regulatory properties SGK-1 could be a key molecule for the induction of early pathological changes in cartilage as well as for the later degradative activities. Therefore, SGK-1 is a very relevant target for the pharmacological intervention in osteoarthritis.
To specifically study the function of SGK-1 during differentiation of cartilage, human SGK-1 was overexpressed in murine ATDC5 cells. In these experiments, it was clearly demonstrated that overexpression of SGK-1 causes inhibition of cartilage synthesis. Both the amount of Alcian blue stained proteoglycan as well as aggrecan mRNA was significantly reduced. A kinase deficient SGK-1 form, however, had no negative effect on these parameters. Regarding the effect of SGK-1 in OA-diseased articular cartilage, several conclusions can be drawn from these experiments. On the one hand, SGK-1 expressing chondrocytes are no longer able to synthesize sufficient extracellular matrix such as proteoglycans, which are essential for the function of the tissue. On the other hand, the cartilage cells are inhibited to compensate for, or repair, degradation processes by increasing the expression of genes such as
aggrecan. Therefore a function of SGK-1 as a potential cause and central factor of OA pathology is confirmed. SGK-1 thus represents a highly relevant target molecule for the development of novel drugs for the treatment of degenerative cartilage changes, especially osteoarthritis.
In view of the relevance of SGK-1 for various physiological processes outlined above, inhibitors of SGK-1 such as the compounds of the present invention can be used in the treatment, including therapy and prophylaxis, of various disease states in which SGK-1 activity plays a role or which are associated with an inappropriate SGK-1 activity, or in which an inhibition, regulation or modulation of signal transduction by SGK-1 is desired by the physician, for example degenerative joint disorders and degenerative cartilage changes including osteoarthritis, osteoarthrosis, rheumatoid arthritis, spondylosis, chondrolysis following joint trauma and prolonged joint immobilization after meniscus or patella injuries or ligament tears, connective tissue disorders such as collagenoses, periodontal disorders, wound-healing disturbances, diabetes including diabetes mellitus, diabetic nephropathy, diabetic neuropathy, diabetic angiopathy and microangiopathy, obesity, metabolic syndrome
(dyslipidaemia), systemic and pulmonary hypertension, cerebral infarctions, cardiovascular diseases including cardiac fibrosis after myocardial infarction, cardiac hypertrophy and heart failure, arteriosclerosis, renal diseases including
glomerulosclerosis, nephrosclerosis, nephritis, nephropathy and electrolyte excretion disorder, and any type of fibrosis and inflammatory processes including liver cirrhosis, lung fibrosis, fibrosing pancreatitis, rheumatism, arthritis, gout, Crohn's disease, chronic bronchitis, radiation fibrosis, sclerodermatitis, cystic fibrosis, scar formation and Alzheimer's disease. Inhibitors of SGK-1 such as the compounds of the present invention can also be used in the treatment of pain including acute pain like pain following injuries, post-operative pain, pain in association with an acute attack of gout and acute pain following jaw-bone surgery interventions, and chronic pain like pain associated with chronic musculoskeletal diseases, back pain, pain associated with osteoarthritis or rheumatoid arthritis, pain associated with inflammation, amputation pain, pain associated with multiple sclerosis, pain associated with neuritis, pain associated with carcinomas and sarcomas, pain associated with AIDS, pain
associated with chemotherapy, trigeminus neuralgia, headache, migraine, cephalalgia, neuropathic pains and post-herpes zoster neuralgia. Inhibitors of SGK-1 such as the compounds of the present invention can also be used in tumor therapy for inhibiting the growth of tumor cells and tumor metastases, and for the treatment of chronic disorders of the locomotor system such as inflammatory, immunologically or metabolically-related acute and chronic arthritides, arthropathies, myalgias and disturbances of bone metabolism. Further, inhibitors of SGK-1 such as the
compounds of the present invention can be used in the treatment of peptic ulcers, especially in forms that are triggered by stress, in the treatment of tinnitus, in the treatment of bacterial infections and in anti-infective therapy, for increasing the learning ability and attention, for counteracting cellular aging and stress and thus increasing life expectancy and fitness in the elderly, in states of neuronal excitability including epilepsy and progressive myoclonic epilepsy of the Lafora type (Lafora disease), in the treatment of glaucoma or cataracts, and in the treatment of
coagulopathies including dysfibrinogenaemia, hypoproconvertinaennia, haemophilia B, Stuart-Prower defect, prothrombin complex deficiency, consumption coagulopathy, fibrinolysis, immunokoagulopathy or complex coagulopathies. Further details about the physiological role of SGK are found in the literature, for example in the mentioned literature articles and others.
The identification of small compounds that specifically inhibit, regulate or modulate signal transduction by SGK, is therefore desirable and an object of the present invention. But besides being effective SGK inhibitors, it is desirable that such inhibitors also have further advantageous properties, for example high bioavailability, stability in plasma and liver, and selectivity versus other kinases or receptors whose inhibition or activation is not intended. Thus, it is an object of the present invention to provide SGK inhibitors which effectively inhibit an aberrant activity of SGK in a pathological context and which have further advantageous properties, for example high bioavailability, stability in plasma and liver, and selectivity versus other kinases and receptors which are not intended to be influenced in an agonistic or antagonistic manner. This object is achieved by providing the novel compounds of the formula I
which exhibit excellent SGK-1 inhibitory activity and are favorable agents with high bioavailability and stability in plasma and liver.
Thus, a subject of the present invention are the compounds of the formula I, in any of their stereoisomeric forms or a mixture of stereoisomeric forms in any ratio, and the pharmaceutically acceptable salts thereof,

If structural elements such as groups, substituents or numbers, for example, can occur several times in the compounds of the formula I, they are all independent of each other and can in each case have any of the indicated meanings, and they can in each case be identical to or different from any other such element. In a
dialkylamino group, for example, the alkyl groups can be identical or different.
Alkyl groups, i.e. saturated hydrocarbon residues, can be linear (straight-chain) or branched. This also applies if these groups are substituted or are part of another group, for example an -O-alkyl group (alkyloxy group, alkoxy group) or an HO-substituted alkyl group (-alkyl-OH, hydroxyalkyl group). Depending on the respective definition, the number of carbon atoms in an alkyl group can be 1 , 2, 3, 4, 5, 6, 7 or 8, or 1 , 2, 3, 4, 5 or 6, or 1 , 2, 3 or 4, or 1 , 2 or 3, or 1 or 2, or 1 . Examples of alkyl are methyl, ethyl, propyl including n-propyl and isopropyl, butyl including n-butyl, sec-butyl, isobutyl and tert-butyl, pentyl including n-pentyl, 1 -methylbutyl, isopentyl, neopentyl and tert-pentyl, hexyl including n-hexyl, 2,2-dimethylbutyl, 3,3-dimethylbutyl, 2-methylpentyl, 3-methylpentyl and isohexyl, heptyl including n-heptyl, and octyl including n-octyl and 2,2-dimethylhexyl. Examples of -O-alkyl groups are methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, isobutoxy, tert-butoxy, n-pentoxy.
A substituted alkyl group can be substituted in any positions, provided that the respective compound is sufficiently stable and is suitable as a pharmaceutical active compound. The prerequisite that a specific group and a compound of the formula I are sufficiently stable and suitable as a pharmaceutical active compound, applies in general with respect to the definitions of all groups in the compounds of the formula I. Independently of any other substituents which can be present on an alkyl group, and unless specified otherwise, alkyl groups can be substituted by one or more fluorine substituents, for example by 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10 or 1 1 fluorine substituents, or by 1 , 2, 3, 4 or 5 fluorine substituents, or by 1 , 2 or 3 fluorine substituents, which can be located in any positions. I.e., independently of any other substituents which can be present on an alkyl group, an alkyl group can be unsubstituted by fluorine substituents, i.e. not carry fluorine substituents, or substituted by fluorine substituents, wherein all alkyl groups in the compounds of the formula I are independent of one
another with regard to the optional substitution by fluorine substituents. For example, in a fluoro-substituted alkyl group one or more methyl groups can carry three fluorine substituents each and be present as trifluoromethyl groups, and/or one or more methylene groups (CH2) can carry two fluorine substituents each and be present as difluoromethylene groups. The explanations with respect to the substitution of a group by fluorine also apply if the group additionally carries other substituents and/or is part of another group, for example of an -O-alkyl group. Examples of fluoro-substituted alkyl groups are -CF3 (trifluoromethyl), -CHF2, -CH2F, -CHF-CF3, -CHF-CHF2, -CHF-CH2F, -CH2-CF3, -CH2-CHF2, -CH2-CH2F, -CF2-CF3, -CF2-CHF2, -CF2-CH2F, -CH2-CHF-CF3, -CH2-CHF-CHF2, -CH2-CHF-CH2F, -CH2-CH2-CF3, -CH2-CH2-CHF2, -CH2-CH2-CH2F, -CH2-CF2-CF3, -CH2-CF2-CHF2, -CH2-CF2-CH2F, -CHF-CHF-CF3, -CHF-CHF-CHF2, -CHF-CHF-CH2F, -CHF-CH2-CF3, -CHF-CH2-CHF2, -CHF-CH2-CH2F, -CHF-CF2-CF3, -CHF-CF2-CHF2, -CHF-CF2-CH2F, -CF2-CHF-CF3, -CF2-CHF-CHF2, -CF2-CHF-CH2F, -CF2-CH2-CF3, -CF2-CH2-CHF2, -CF2-CH2-CH2F, -CF2-CF2-CF3, -CF2-CF2-CHF2, or -CF2-CF2-CH2F. Examples of fluoro-substituted -O-alkyl groups are trifluoromethoxy (-O-CF3), 2,2,2-trifluoroethoxy, pentafluoroethoxy and 3,3,3-trifluoropropoxy. With respect to all groups or substituents in the compounds of the formula I which can be an alkyl group which can generally contain one or more fluorine substituents, as an example of groups or substituents containing fluorine-substituted alkyl, which may be included in the definition of the group or substituent, the group CF3 (trifluoromethyl), or a respective group such as -O-CF3, may be mentioned.
The above explanations with respect to alkyl groups apply correspondingly to alkyl groups which in the definition of a group in the compounds of the formula I are bonded to two adjacent groups, or linked to two groups, and may be regarded as divalent alkyl groups (alkanediyl groups), like in the case of the alkyl part of a substituted alkyl group. Thus, such groups can also be linear or branched, the bonds to the adjacent groups can be located in any positions and can start from the same carbon atom or from different carbon atoms, and they can be unsubstituted or substituted by fluorine substituents independently of any other substituents.
Examples of such divalent alkyl groups are -CH2-, -CH2-CH2-, -CH2-CH2-CH2-,
-CH2-CH2-CH2-CH2-, -CH2-CH2-CH2-CH2-CH2-, -CH2-CH2-CH2-CH2-CH2-CH2-, -CH(CH3)-, -C(CH3)2-, -CH(CH3)-CH2-, -CH2-CH(CH3)-, -C(CH3)2-CH2-,
-CH2-C(CH3)2-. Examples of fluoro-substituted alkanediyl groups, which can contain 1 , 2, 3, 4, 5 or 6 fluorine substituents, or 1 , 2, 3 or 4 fluorine substituents, or 1 or 2 fluorine substituents, for example, are -CF2-, -CHF-, -CHF-CHF2-, -CHF-CHF-, -CH2-CF2-, -CH2-CHF-, -CF2-CF2-, -CF2-CHF-, -CH2-CHF-CF2-, -CH2-CHF-CHF-, -CH2-CH2-CF2-, -CH2-CH2-CHF, -CH2-CF2-CF2-, -CH2-CF2-CHF-, -CHF-CHF-CF2-, -CHF-CHF-CHF-, -CHF-CH2-CF2-, -CHF-CH2-CHF-, -CHF-CF2-CF2-, -CHF-CF2-CHF-, -CF2-CHF-CF2-, -CF2-CHF-CHF-, -CF2-CH2-CF2-, -CF2-CH2-CHF-, -CF2-CF2-CF2-, or -CF2-CF2-CHF-.
The number of ring carbon atoms in a (C3-C7)-cycloalkyl group can be 3, 4, 5, 6 or 7. Examples of cycloalkyi are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl. Independently of any other substituents which can be present on a cycloalkyi group, and unless specified otherwise, cycloalkyi groups can be
substituted by one or more (Ci-C4)-alkyl substituents, for example by 1 , 2, 3 or 4 identical or different (Ci-C4)-alkyl substituents, for example by methyl groups, which can be located in any positions. I.e., independently of any other substituents which can be present on a cycloalkyi group, a cycloalkyi group can be unsubstituted by (Ci-C4)-alkyl substituents, i.e. not carry (Ci-C4)-alkyl substituents, or substituted by (Ci-C4)-alkyl substituents, wherein all cycloalkyi groups in the compounds of the formula I are independent of one another with regard to the optional substitution by (Ci-C4)-alkyl substituents. Examples of such alkyl-substituted cycloalkyi groups are 1 -methylcyclopropyl, 2,2-dimethylcyclopropyl, 1 -methylcyclopentyl, 2,3-dimethylcyclopentyl, 1 -methylcyclohexyl, 4-methylcyclohexyl, 4-isopropylcyclohexyl, 4-tert-butylcyclohexyl, 3,3,5,5-tetramethylcyclohexyl. Independently of any other substituents including (Ci-C4)-alkyl substituents which can be present on a cycloalkyi group, and unless specified otherwise, cycloalkyi groups can further be substituted by one or more fluorine substituents, for example by 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10 or 1 1 fluorine substituents, or by 1 , 2, 3, 4 or 5 fluorine substituents, or by 1 , 2 or 3 fluorine substituents, which can be located in any positions and can also be present in a (Ci-C4)-alkyl substituent. I.e., independently of any other substituents which can be
present on a cycloalkyl group, a cycloalkyl group can be unsubstituted by fluorine substituents, i.e. not carry fluorine substituents, or substituted by fluorine substituents, wherein all cycloalkyl groups in the compounds of the formula I are independent of one another with regard to the optional substitution by fluorine substituents.
Examples of fluoro-substituted cycloalkyl groups are 1 -fluorocyclopropyl, 2,2-difluorocyclopropyl, 3,3-difluorocyclobutyl, 1 -fluorocyclohexyl, 4,4-difluorocyclohexyl, 3,3,4,4,5,5-hexafluorocyclohexyl. Cycloalkyl groups can also be substituted
simultaneously by fluorine and alkyl. Examples of the group -(Ci-C4)-alkyl-(C3-C7)-cycloalkyl are cyclopropylmethyl-, cyclobutylmethyl-, cyclopentylmethyl-,
cyclohexylmethyl-, cycloheptylmethyl-, 1 -cyclopropylethyl-, 2-cyclopropylethyl-, 1 -cyclobutylethyl-, 2-cyclobutylethyl-, 1 -cyclopentylethyl-, 2-cyclopentylethyl-, 1 -cyclohexylethyl-, 2-cyclohexylethyl-, 1 -cycloheptylethyl-, 2-cycloheptylethyl-. In one embodiment of the invention, a -(Ci-C4)-alkyl-(C3-C7)-cycloalkyl group in any one or more occurrences of such a group, independently of any other occurrences, is a -(Ci-C2)-alkyl-(C3-C7)-cycloalkyl group, in another embodiment a -CH2-(C3-C7)-cycloalkyl group. In the group -(Ci-C4)-alkyl-(C3-C7)-cycloalkyl, and likewise in all other groups, the terminal hyphen denotes the free bond via which the group is bonded, and thus indicates via which subgroup a group composed of subgroups is bonded.
In substituted phenyl groups, including phenyl groups representing Ar, for example, the substituents can be located in any positions. In monosubstituted phenyl groups, the substituent can be located in position 2, in position 3 or in position 4. In
disubstituted phenyl groups, the substituents can be located in positions 2 and 3, in positions 2 and 4, in positions 2 and 5, in positions 2 and 6, in positions 3 and 4, or in positions 3 and 5. In trisubstituted phenyl groups, the substituents can be located in positions 2, 3 and 4, in positions 2, 3 and 5, in positions 2, 3 and 6, in positions 2, 4 and 5, in positions 2, 4 and 6, or in positions 3, 4 and 5. If a phenyl group carries four substituents, some of which can be fluorine atoms, for example, the substituents can be located in positions 2, 3, 4 and 5, in positions 2, 3, 4 and 6, or in positions 2, 3, 5 and 6. If a polysubstituted phenyl group or any other polysubstituted group carries different substituents, each substituent can be located in any suitable position, and the present invention comprises all positional isomers. The number of substituents in
a substituted phenyl group can be 1 , 2, 3, 4 or 5. In one embodiment of the invention, the number of substituents in a substituted phenyl group, is 1 , 2, 3 or 4, in another embodiment 1 , 2 or 3, in another embodiment 1 or 2, in another embodiment 1 , wherein the number of substituents in any occurrence of such a substituted group is independent of the number of substituents in other occurrences.
In heterocyclic groups, including the groups Het1 , Het2, Het3, heterocyclic groups representing Ar, heterocyclic groups R30 and other heterocyclic rings which can be present in the compounds of the formula I, such as rings formed by two group together with the atom or atoms carrying them, the hetero ring members can be present in any combination and located in any suitable ring positions, provided that the resulting group and the compound of the formula I are suitable and sufficiently stable as a pharmaceutical active compound. In one embodiment of the invention, two oxygen atoms in any heterocyclic ring in the compounds of the formula I cannot be present in adjacent ring positions. In another embodiment of the invention, two hetero ring members selected from the series consisting of oxygen atoms and sulfur atoms cannot be present in adjacent ring positions in any heterocyclic ring in the compounds of the formula I. In another embodiment of the invention, two hetero ring members selected from the series consisting of nitrogen atoms carrying an exocyclic group like a hydrogen atom or a substituent, sulfur atoms and oxygen atoms cannot be present in adjacent ring positions in any heterocyclic ring in the compounds of the formula I. The choice of hetero ring members in an aromatic heterocyclic ring is limited by the prerequisite that the ring is aromatic, i.e. it comprises a cyclic system of six delocalized pi electrons in case of a monocycle or 10 delocalized pi electrons in case of a bicycle. Monocyclic aromatic heterocycles are 5-membered or 6-membered rings and, in the case of a 5-membered ring, comprise one ring heteroatom selected from the series consisting of oxygen, sulfur and nitrogen, wherein this ring nitrogen carries an exocyclic group like a hydrogen atom or a substituent, and optionally one or more further ring nitrogen atoms, and, in the case of a 6-membered ring, comprise one or more nitrogen atoms as ring heteroatoms, but no oxygen atoms and sulfur atoms as ring heteroatoms. Heterocyclic groups in the compounds of the formula I can be bonded via a ring carbon atom or a ring nitrogen atom, unless specified
otherwise in the definition of the respective group, wherein a heterocyclic group can be bonded via any suitable carbon atom or nitrogen atom, respectively, in the ring. In substituted heterocyclic groups, the substituents can be located in any positions.
The number of ring heteroatoms which can be present in a heterocyclic group in the compounds of the formula I, the number of ring members which can be present, and the degree of saturation, or hydrogenation, i.e. whether the heterocyclic group is saturated and does not contain a double bond within the ring, or whether it is partially unsaturated and contains one or more, for example one or two, double bonds within the ring but is not aromatic, or whether it is aromatic and thus contains two double bonds within the ring in the case of a 5-membered monocyclic aromatic heterocycle and three double bonds within the ring in the case of a 6-membered monocyclic aromatic heterocycle, for example, is specified in the definitions of the individual groups in the compounds of the formula I. Examples of heterocyclic ring systems, from which heterocyclic groups in the compounds of the formula I including, for example, Het1 , Het2, Het3, heterocyclic groups representing Ar, heterocyclic groups R30 and rings formed by two groups together with the atom or atoms carrying them, can be derived, and from any one or more of which any of the heterocyclic groups in the compounds of the formula I is selected in one embodiment of the invention, provided that the ring system is comprised by the definition of the group, are oxetane, thietane, azetidine, furan, tetrahydrofuran, thiophene, tetrahydrothiophene, pyrrole, pyrroline, pyrrolidine, [1 ,3]dioxole, [1 ,3]dioxolane, isoxazole ([1 ,2]oxazole),

Ring sulfur atoms, in particular in saturated and partially unsaturated heterocycles, can generally carry one or two oxo groups, i.e. doubly bonded oxygen atoms (=O), and in such heterocycles, besides a ring sulfur atom, also an S(O) group (S(=O)) and an S(O)2 group (S(=O)2) can be present as hetero ring member.
As mentioned, unless specified otherwise in the definition of the respective group in the compounds of the formula I, heterocyclic groups can be bonded via any suitable ring carbon atom and ring nitrogen atom, for example in the case of heterocyclic groups representing R30.

The present invention comprises all stereoisomeric forms of the compounds of the formula I, for example all enantiomers and diastereomers including cis/trans isomers. The invention likewise comprises mixtures of two or more stereoisomeric forms, for example mixtures of enantiomers and/or diastereomers including cis/trans isomers, in all ratios. Asymmetric centers contained in the compounds of the formula I can all independently of each other have S configuration or R configuration. The invention relates to enantiomers, both the levorotatory and the dextrorotatory antipode, in enantiomerically pure form and essentially enantiomerically pure form, and in the form of their racemate, i.e. a mixture of the two enantiomers in molar ratio of 1 :1 , and in the form of mixtures of the two enantiomers in all ratios. The invention likewise relates to diastereomers in the form of pure and essentially pure diastereomers and in the form of mixtures of two or more diastereomers in all ratios. The invention also comprises all cis/trans isomers of the compounds of the formula I in pure form and essentially pure form, and in the form of mixtures of the cis isomer and the trans isomer in all ratios. Cis/trans isomerism can occur in substituted rings. The preparation of individual stereoisomers, if desired, can be carried out by resolution of a mixture according to customary methods, for example, by chromatography or crystallization, or by use of stereochemically uniform starting compounds in the synthesis, or by stereoselective reactions. Optionally, before a separation of stereoisomers a derivatization can be carried out. The separation of a mixture of stereoisomers can be carried out at the stage of the compound of the formula I or at the stage of an intermediate in the course of the synthesis. For example, in the case of a compound of the formula I containing an asymmetric center the individual enantiomers can be prepared by preparing the racemate of the compound of the formula I and resolving it into the enantiomers by high pressure liquid
chromatography on a chiral phase according to standard procedures, or resolving the racemate of any intermediate in the course of its synthesis by such chromatography or by crystallization of a salt thereof with an optically active amine or acid and converting the enantiomers of the intermediate into the enantiomeric forms of the final compound of the formula I, or by performing an enantioselective reaction in the course of the synthesis. The invention also comprises all tautomeric forms of the compounds of the formula I.
Besides the free compounds of the formula I, i.e. compounds in which acidic and basic groups are not present in the form of a salt, the present invention comprises also salts of the compounds of the formula I, in particular their physiologically acceptable salts, or toxicologically acceptable salts, or pharmaceutically acceptable salts, which can be formed on one or more acidic or basic groups in the compounds of the formula I, for example on basic heterocyclic moieties. The compounds of the formula I may thus be deprotonated on an acidic group by an inorganic or organic base and be used, for example, in the form of the alkali metal salts. Compounds of the formula I comprising at least one basic group may also be prepared and used in the form of their acid addition salts, for example in the form of pharmaceutically acceptable salts with inorganic acids and organic acids, such as salts with
hydrochloric acid and thus be present in the form of the hydrochlorides, for example. Salts can in general be prepared from acidic and basic compounds of the formula I by reaction with an acid or base in a solvent or diluent according to customary procedures. If the compounds of the formula I simultaneously contain an acidic and a basic group in the molecule, the invention also includes internal salts (betaines, zwitterions) in addition to the salt forms mentioned. The present invention also comprises all salts of the compounds of the formula I which, because of low physiological tolerability, are not directly suitable for use as a pharmaceutical, but are suitable as intermediates for chemical reactions or for the preparation of
physiologically acceptable salts, for example by means of anion exchange or cation exchange.

More specifically, suitably substituted starting 1 H-pyrazolo[3,4-d]pyrimidine and 1 H-pyrazolo[4,3-c]pyridine derivatives can be employed as building blocks in the preparation of the compounds of formula I, which can be synthesized from suitable precursor compounds, which allow the introduction of a variety of substituents into the various positions of the 1 H-pyrazolo[3,4-d]pyrimidine or 1 H-pyrazolo[4,3-c]pyridine ring system and which can be chemically modified further in order to finally arrive at the compound of the formula I having the desired substituent pattern. For the synthesis of the 1 H-pyrazolo[3,4-d]pyrimidine and 1 H-pyrazolo[4,3-c]pyridine ring system, use can also be made of procedures and transformations which are described in the literature with respect to indazoles.
