Description
[0001] The present invention relates to carboxylic acid aromatic amides of general formula (I) as described and defined herein, to pharmacological compositions and combinations comprising said compounds and to the use of said compounds for manufacturing a pharmaceutical composition for the treatment or prophylaxis of a disease or disorder and for the treatment of pains, which are associated with such diseases, in particular of Bradykinin B1 receptor associated disorders which are related to inflammation or at least partially driven by neurogenic events like diseases related to chronic pain or frequent pain conditions like but not restricted to osteoarthritis, rheumatoid arthritis, gout, inflammatory bowel disease, and endometriosis and diseases related to Bradykinin B1 receptor activation and / or up-regulation in affected tissue like but not restricted to asthma, fibrosis in various tissues or diabetes as a sole agent or in combination with other active ingredients.BACKGROUND OF THE INVENTION
[0002] The present invention relates to chemical compounds that antagonize the effects of human Bradykinin B1 receptor (Gene Name BDKRB1, Gene ID 623).
[0003] The Bradykinin B1 receptor is a membrane-bound G-protein coupled receptor, which is linked to a second messenger system that triggers increase of intracellular calcium concentrations. The main signalling pathway is linked to Gq protein and phospholipase C (Leeb-Lundberg, L. M. et al. (2005), Pharmacol Rev 57(1): 27-77). Activation of Bradykinin B1 receptor has been shown to be pro-algesic, pro-fibrotic, and proinflammatory while Bradykinin B1 receptor antagonists had clear anti-inflammatory and analgesic effects in various animal models (Gougat, J. B. et al. (2004), J Pharmacol Exp Ther 309(2): 661-669; Dias, J. P. et al. (2007), Br J Pharmacol 152(2): 280-287; Schuelert, N. et al. (2015), Eur J Pain 19(1): 132-142). As consequence of Bradykinin B1 receptor activity increased gene expression and protein levels of proinflammatory cytokines like e.g. Il-6 and Il-8 that attract and activate inflammatory leucocytes, increase of PGE2 (Prostaglandin 2) levels and therefore activation of the inflammation related prostaglandin pathway, phosphorylation and upregulation of TRPV1 (Transient Receptor Potential Vanilloid 1) receptors which are important mediators of pain transduction and induction of neurogenic inflammation (neuropeptide release in inflamed tissue) were observed (Phagoo, S. B. et al. (1999). Mol Pharmacol 56(2): 325-333; Westermann, D. et al. (2009), Diabetes 58(6): 1373-1381; Walsh, D. A. et al. (2006), Curr Drug Targets 7(8): 1031-1042; Farkas S. et al. (2011), Drugs of the Future 36(4): 301-319). Bradykinin B1 receptor agonists are endogenously produced by the activated kallikrein-kinin system. This system consists of circulating kininogens, the ubiquitous expressed proteolytic enzymes kallikreins which are activated by tissue damage, and kinins which are formed by activated kallikreins out of kininogens (Review Fincham, C. I. et al. (2009), Expert Opin Ther Pat 19(7): 919-941). These kinins (e.g. bradykinin, kalidin, des-Arg9-bradykinin, des-Arg10-kalidin) are proinflammatory peptides that mediate vascular and pain responses to tissue injury, with functions in cardiovascular homeostasis, contraction or relaxation of smooth muscle, inflammation and nociception. They exert most of their effects by interacting with two classes of G-protein-coupled receptors called Bradykinin receptor 1 and 2. The classification of the kinin receptors was originally achieved by means of pharmacological studies originally carried out at the end of the 1970s. During the 1990s, the existence of Bradykinin B1 receptor and B2 receptors was further confirmed through cloning and genetic deletion studies (Menke, J. G. et al. (1994), J Biol Chem 269(34): 21583-21586). The past 30 years of research on the kinin system has indicated that both Bradykinin B1 receptor and B2 receptor are involved in pain and inflammation (Leeb-Lundberg, L. M. et al. (2005), Pharmacol Rev 57(1): 27-77; Marceau, F. (2005), Trends Pharmacol Sci 26(3): 116-118; Marceau, F. (2004), Nat Rev Drug Discov 3(10): 845-852; Chen, J. J. et al. (2007), Expert Opin Ther Targets 11 (1): 21 -35).
[0004] It has been demonstrated that the B2 receptor is widely expressed in a constitutive manner throughout most mammalian tissues. In contrast, the Bradykinin B1 receptor is not constitutively expressed to a great extent under normal conditions, but is up-regulated under various inflammatory conditions such as asthma, arthritis and osteoarthritis, sepsis and type-1 diabetes, as well as by some neuropathological diseases such as epilepsy, stroke and multiple sclerosis. Bradykinin B1 receptor up-regulation can be induced for example by Il-1beta (Phagoo, S. B.et al. (1999), Mol Pharmacol 56(2): 325-333) and Bradykinin B2 receptor activation (NF-kB activation leading to IL1b expression in fibroblasts) (Leeb-Lundberg, L. M. et al. (2005), Pharmacol Rev 57(1): 27-77).
[0005] Once upregulated, the Bradykinin B1 receptor is expressed on neurons, macrophages, neutrophils, fibroblasts, smooth muscle cells and the vascular endothelium (Fincham, C. I. et al. (2009), Expert Opin Ther Pat 19(7): 919-941). Recent findings suggest that the Bradykinin B1 receptor expressed in the peripheral and in the central nervous system is involved in processing of inflammatory pain (Schuelert, N. et al. (2015). Eur J Pain 19(1): 132-142).
[0006] In contrast to Bradykinin B2 receptor and many other GPCRs (G protein-coupled receptors), the Bradykinin B1 receptor does not show agonist induced internalization or relevant desensitization (Prado, G. N. et al. (2002), J Cell Physiol 193(3): 275-286; Eisenbarth, H. et al. (2004), Pain 110(1-2): 197-204). Activation of Bradykinin B1 receptor triggers auto-induction of the receptor. This might lead to an augmentation of the inflammatory or pain-inducing processes.
[0007] Therefore, Bradykinin B1 receptor has been suggested to have a pivotal role including but not limited to several chronic diseases involving diabetes, fibrosis, inflammation, neuroinflammation, neurodegeneration, inflammatory pain, and neuropathic pain (Campos, M. M. et al. (2006), Trends Pharmacol Sci 27(12): 646-651; Wang, P. H. et al. (2009), Int Immunopharmacol 9(6): 653-657; Passos, G. F. et al. (2013), Am J Pathol 182(5): 1740-1749; Gobeil, F. et al. (2014), Peptides 52: 82-89; Huart, A. (2015), Front Pharmacol 6: 8). The contribution of Bradykinin B1 receptor activation in inflammation and pain processes is supported by the demonstration that Bradykinin B1 receptor knockout mice have a largely decreased response to nociceptive and proinflammatory stimuli (Ferreira, J. et al. (2001), Neuropharmacology 41(8): 1006-1012; Ferreira, J. et al. (2005), J Neurosci 25(9): 2405-2412.). The therapeutic impact of Bradykinin B1 receptor blockage for inflammation related diseases is supported further by the pharmacological properties of Bradykinin B1 receptor antagonists shown in many inflammatory and neuropathic pain models (Gougat, J. B. et al. (2004), J Pharmacol Exp Ther 309(2): 661-669; Fox, A. et al. (2005), Br J Pharmacol 144(7): 889-899).
[0008] The fact that Bradykinin B1 receptor expression is induced under disease conditions clearly raises the possibility that therapeutic use of Bradykinin B1 receptor antagonists should be devoid of undesired adverse effects. This property supports the suitability of Bradykinin B1 receptor antagonists for treatment of benign diseases like endometriosis due the expected positive risk benefit ratio. The patient populations for nociceptive pain and neuropathic pain are large, and are driven by separate disease trends that necessitate pain relief. Chronic pain of moderate to severe intensity occurs in 19% of adult Europeans, seriously affecting the quality of their social and working lives (Breivik et al., Eur J Pain. 2006 May;10(4):287-333.). Unfortunately, current treatments for pain are only partially effective, and many cause life-style altering, debilitating, and / or dangerous side effects. For example, non-steroidal anti-inflammatory drugs (NSAIDS) such as aspirin, ibuprofen, and indomethacin are moderately effective against inflammatory pain but they are also renally toxic, and high doses tend to cause gastrointestinal irritation, ulceration, bleeding, confusion and increased cardiovascular risk. Notably, Vioxx was withdrawn from the market in 2004 due to a risk of myocardial infarction and stroke. Patients treated with opioids frequently experience confusion and constipation, and long-term opioid use is associated with tolerance and addiction. Local anaesthetics such as lidocaine and mexiletine simultaneously inhibit pain and cause loss of normal sensation. In addition, when used systemically, local anaesthetics are associated with adverse cardiovascular effects. Thus, there is currently an unmet need in the treatment of chronic pain in general.
[0009] Especially in gynaecological therapy field, endometriosis is the diseases associated with chronic pelvic pain severely affecting quality of life of the patients. Globally, approximately 11% of women aged 15-49 years are affected by endometriosis and additional 6% of women suffer from symptoms suggestive for endometriosis. Main symptoms of endometriosis are chronic or frequent pelvic pain, dyspareunia, dyschezia, dysuria and sub-or infertility. These symptoms severely impair quality of life of patients. Diagnosis of the disease involves a complete medical history, a physical examination and a laparoscopy. As an ultimate confirmation of endometriosis can only be made invasively and symptoms are often unspecific, the mean time from initial symptoms to diagnosis of endometriosis is about 7-10 years. Therefore, endometriosis is under-diagnosed and the number of affected women might be much higher than anticipated. Recently published EndoCost study demonstrated that cost of productivity loss of €6,298 per woman were double the healthcare cost of €3,113 per women, driven mainly by surgery and monitoring visit (Gao, X. et al. (2006), Fertil Steril 86(6): 1561-1572; Simoens S, et al. Hum Reprod (2012), 27(5):1292-9; De Graaff A, et al. (2013), Hum Reprod; 28(10): 2677-85).
[0010] Endometriosis is characterized by growth of endometrial tissue outside of the uterine cavity forming benign tumours (lesions) in the affected part of the body. Depending on lesion location and innervation severity of pain symptoms is observed. Up-regulation of various inflammation markers observed in the affected tissue and in the peritoneal tissue underline the inflammatory character of the disease (Stratton, P. et al. (2011), Hum Reprod Update 17(3): 327-346; Gao, X. et al. (2006), Fertil Steril 86(6): 1561-1572; Laux-Biehlmann et al. (2015), Trends Pharmacol Sci 36(5): 270-276).
[0011] The Bradykinin B1 receptor was identified in endometriosis lesion by immune-histological-chemical (IHC) staining (Yoshino et al. Journal of Reproductive Immunology 112 (2015) 121-140; www.proteinatlas.org) and analysis of mRNA expression of Bradykinin B1 receptor in affected tissue shows a positive correlation to pain severity reported by endometriosis patients. Data describing a role of Bradykinin B1 receptors in affecting the outcome of an endometriosis mouse model (Jingwei, C. et al. (2015), J Tradit Chin Med 35(2): 184-191) further support the concept to treat endometriosis with Bradykinin B1 receptor antagonists.
[0012] Suspected endometriosis is initially treated with non-steroidal anti-inflammatory drugs (NSAID) or combined oral contraceptives (COC) which are used off label. This procedure delays endometriosis diagnosis. Laparoscopy is the gold standard for endometriosis diagnosis which is performed when the initial treatment options fail. During laparoscopy, endometriotic lesions are ablated. However, this procedure is accompanied by a high recurrence rate. Approximately, 70% of treated patients have persistent symptoms that are not managed. Currently, there is no long-term medication available in COC / P (C ombined O ral C ontraceptives / P rogestin) non-responder endometriosis patients in which COCs and progestins failed. Treatment with Gonadotropin Releasing Hormone (GnRH) agonists, which are used as second line therapy (without proof of being superior versus first line) are only approved for short-term treatment (6 months). After GnRH agonist application, systemic estradiol levels are suppressed up to 90% leading to chemical castration with menopausal side effects like bone mass loss and hot flushes. Therefore, new and long-term treatment options with reduced side-effects and high efficacy for patients with COC / P non-responder endometriosis are urgently needed.
[0013] On this background the Bradykinin B1 receptor antagonists are of value for treatment of disorders which are related to inflammation or at least partially driven by neurogenic events like diseases related to chronic pain or frequent pain conditions like but not restricted to osteoarthritis (Kaufman, G. N. et al. (2011), Arthritis Res Ther 13(3): R76), rheumatoid arthritis (Cassim, B. et al. (2009), Rheumatology 48(5): 490-496), gout (Silva, C. R. et al.

M. et al. (2009), J Leukoc Biol 85(3): 544-552), atherosclerosis, diabetes (Dias, J. P. et al. (2012), J Cardiovasc Pharmacol 60(1): 61-69), adipositas including metabolic syndrome (Dias, J. P. et al. (2012), Diabetes Obes Metab 14(3): 244-253), diseases related to muscle atrophy including cachexia (Parreiras, E. S. L. T. et al. (2014), Clin Sci 127(3): 185-194) not limited to cancer cachexia, neuropathic pain (Luiz, A. P. et al. (2015), Neuroscience 300: 189-200), pruritus or itch (Hosogi, M. et al. (2006), Pain 126(1-3): 16-23), cancer (da Costa, P. L. et al. (2014), Cancer Lett 345(1): 27-38), neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) or Alzheimer's disease (Lacoste, et al. (2013) J Neuroinflammation 10: 57), fibrosis in cardiacs (Westermann, D. et al. (2009), Diabetes 58(6): 1373-1381), fibrosis in renal (Huart, A. et al. (2015), Front Pharmacol 6: 8) and fibrosis in lung tissues, overactive urinary bladder syndrome and cystitis (Forner, S. et al. (2012), Br J Pharmacol 167(8): 1737-1752 and Belichard, P. et al (1999), Br J Pharmacol 128(1):213-219), impaired or painful wound healing (Schremmer-Danninger, E. et al. (2004), Biol Chem 385(11): 1069-1076) and sepsis (Murugesan, P et al. (2016), J Infect Dis 213(4): 532-540).
[0014] Several new Bradykinin B1 receptor antagonists are known from prior art (Expert Opinion on Therapeutic Patents (2012), 22:12, 1443-1452). Various approaches for finding new Bradykinin B1 receptor antagonists are described, in particular peptidic structures and small molecules. Especially, arylsulfonamides and so-called cyclopropyl-carboxamides as the two main types of small molecules were investigated during the last decade.
[0015] WO2003 / 065789 (Merck) disclose bradykinin B1 receptor antagonists or inverse agonists of the following general formula which are useful in the treatment or prevention of symptoms such as pain and inflammation associated with the bradykinin B1 pathway.
[0016] Merck was developing the bradykinin B1 receptor antagonist MK-0686 (structure shown below) for the potential treatment of pain and inflammation. Several phase II trials in subjects with osteoarthritis and with post-herpetic neuralgia were initiated. Merck accounted that the compound has a suboptimal pharmacokinetic profile due to metabolic lability.
[0017] Jerini AG, now Shire Group, investigated active Bradykinin B1 receptor antagonists, for example (see WO2009 / 036996) which was reported to have in addition to its activity and acceptable penetration profile reasonable aqueous solubility and pharmacokinetic profile in rat, whereas its human metabolic stability was still poor (Schaudt M, Locardi E, Zischinsky G, et al., Bioorg Med Chem Lett 2010;20:1225-8). Jerini exchanged the cyclopropyl-carboxamide moiety to a semicarbazide or to a five-membered diamino-heterocyclic ring or even to hydroxyureas without any explanation.
[0018] Starting with arylsulfonamide compounds as Bradykinin B1 receptor antagonists, Boehringer Ingelheim reported about several cyclopropyl-carboxamides out of their further development compounds like of the following structure or related to that emerged with the highest binding affinity measured on human B1R-expressing CHO cells (Expert Opinion on Therapeutic Patents (2012), 22:12, 1443-1452).

[0020] A majority of the compounds have a K i value below 20 nM on human recombinant Bradykinin receptors (expressed in CHO cells). Several indolyl compounds are disclosed and represented by the following compound: In WO2012 / 112567 (Georgetown University) small molecule inhibitors of ATP / GTP binding protein like 2 (AGBL2) of the formula are disclosed wherein Ar is substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl; L is absent or -(CHR 6< )-, wherein R 6< is substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl; and R 1< , R 2< , R 3< , R 4< , and R 5< are each independently selected from hydrogen, halogen, hydroxyl, cyano, nitro, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted amino, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted alkoxyl, substituted or unsubstituted aryloxyl, substituted or unsubstituted carbonyl, or substituted or unsubstituted carboxyl. The compounds can be used in methods for treating or preventing cancer and neurologic disorders were described Aromatic Amides with carboxylic acid groups and cyclopropyl moiety are not specifically disclosed.

R 4 is an optionally substituted aryl or an optionally substituted heteroaryl. R 1< is independently an optionally substituted C 1 -C 6 aliphatic, an optionally substituted aryl, an optionally substituted heteroaryl, an optionally substituted C 3 -C 10 membered cycloaliphatic or an optionally substituted 4 to 10 membered heterocycloaliphatic, carboxy, amido, amino, halo, or hydroxy, provided that at least one R 1< is an optionally substituted aryl or an optionally substituted heteroaryl and said R 1< is attached to the 3- or 4-position of the phenyl ring.

[0078] As used herein, the term "leaving group" means an atom or a group of atoms that is displaced in a chemical reaction as stable species taking with it the bonding electrons. In particular, such a leaving group is selected from the group comprising: halide, in particular fluoride, chloride, bromide or iodide, (methylsulfonyl)oxy, [(trifluoromethyl)sulfonyl]oxy, [(nonafluorobutyl)sulfonyl]oxy, (phenylsulfonyl)oxy, [(4-methylphenyl)sulfonyl]oxy, [(4-bromophenyl)sulfonyl]oxy, [(4-nitrophenyl)-sulfonyl]oxy, [(2-nitrophenyl)sulfonyl]oxy, [(4-isopropylphenyl)sulfonyl]oxy, [(2,4,6-triisopropylphenyl)sulfonyl]oxy, [(2,4,6-trimethylphenyl)sulfonyl]oxy, [(4-tert-butylphenyt)sulfonyl]oxy and [(4-methoxyphenyl)sulfonyl]oxy.
[0079] It is possible for the compounds of general formula (I) to exist as isotopic variants. The invention therefore includes one or more isotopic variant(s) of the compounds of general formula (I), particularly deuterium-containing compounds of general formula (I).
[0080] The term "Isotopic variant" of a compound or a reagent is defined as a compound exhibiting an unnatural proportion of one or more of the isotopes that constitute such a compound.
[0081] The term "Isotopic variant of the compound of general formula (I)" is defined as a compound of general formula (I) exhibiting an unnatural proportion of one or more of the isotopes that constitute such a compound.
[0082] The expression "unnatural proportion" means a proportion of such isotope, which is higher than its natural abundance. The natural abundances of isotopes to be applied in this context are described in "Isotopic Compositions of the Elements 1997", Pure Appl. Chem., 70(1), 217-235, 1998, which is incorporated herein by reference.
[0083] Examples of such isotopes include stable and radioactive isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, bromine and iodine, such as 2< H (deuterium), 3< H (tritium), 11< C, 13< C, 14< C, 15< N, 17< O, 18< O, 32< P, 33< P, 33< S, 34< S, 35< S, 36< S, 18< F, 36< Cl, 82< Br, 123< I, 124< I, 125< I, 129< I and 131< I, respectively.
[0084] With respect to the treatment and / or prophylaxis of the disorders specified herein the isotopic variant(s) of the compounds of general formula (I) preferably contain deuterium ("deuterium-containing compounds of general formula (I)"). Isotopic variants of the compounds of general formula (I) in which one or more radioactive isotopes, such as 3< H or 14< C, are incorporated are useful e.g. in drug and / or substrate tissue distribution studies. These isotopes are particularly preferred for the ease of their incorporation and detectability. Positron emitting isotopes such as 18< F or 11< C may be incorporated into a compound of general formula (I). These isotopic variants of the compounds of general formula (I) are useful for in vivo imaging applications. Deuterium-containing and 13< C-containing compounds of general formula (I) can be used in mass spectrometry analyses in the context of preclinical or clinical studies.
[0085] Isotopic variants of the compounds of general formula (I) can generally be prepared by methods known to a person skilled in the art, such as those described in the schemes and / or examples herein, by substituting a reagent for an isotopic variant of said reagent, preferably for a deuterium-containing reagent. Depending on the desired sites of deuteration, in some cases deuterium from D 2 O can be incorporated either directly into the compounds or into reagents that are useful for synthesizing such compounds. Deuterium gas is also a useful reagent for incorporating deuterium into molecules. Catalytic deuteration of olefinic bonds and acetylenic bonds is a rapid route for incorporation of deuterium. Metal catalysts (i.e. Pd, Pt, and Rh) in the presence of deuterium gas can be used to directly exchange deuterium for hydrogen in functional groups containing hydrocarbons. A variety of deuterated reagents and synthetic building blocks are commercially available from companies such as for example C / D / N Isotopes, Quebec, Canada; Cambridge Isotope Laboratories Inc., Andover, MA, USA; and CombiPhos Catalysts, Inc., Princeton, NJ, USA.
[0086] The term "deuterium-containing compound of general formula (I)" is defined as a compound of general formula (I), in which one or more hydrogen atom(s) is / are replaced by one or more deuterium atom(s) and in which the abundance of deuterium at each deuterated position of the compound of general formula (I) is higher than the natural abundance of deuterium, which is about 0.015%. Particularly, in a deuterium-containing compound of general formula (I) the abundance of deuterium at each deuterated position of the compound of general formula (I) is higher than 10%, 20%, 30%, 40%, 50%, 60%, 70% or 80%, preferably higher than 90%, 95%, 96% or 97%, even more preferably higher than 98% or 99% at said position(s). It is understood that the abundance of deuterium at each deuterated position is independent of the abundance of deuterium at other deuterated position(s).
[0087] The selective incorporation of one or more deuterium atom(s) into a compound of general formula (I) may alter the physicochemical properties (such as for example acidity [C. L. Perrin, et al., J. Am. Chem. Soc., 2007, 129, 4490], basicity [C. L. Perrin et al., J. Am. Chem. Soc., 2005, 127, 9641], lipophilicity [B. Testa et al., Int. J. Pharm., 1984, 19(3), 271] and / or the metabolic profile of the molecule and may result in changes in the ratio of parent compound to metabolites or in the amounts of metabolites formed. Such changes may result in certain therapeutic advantages and hence may be preferred in some circumstances. Reduced rates of metabolism and metabolic switching, where the ratio of metabolites is changed, have been reported (A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). These changes in the exposure to parent drug and metabolites can have important consequences with respect to the pharmacodynamics, tolerability and efficacy of a deuterium-containing compound of general formula (I). In some cases, deuterium substitution reduces or eliminates the formation of an undesired or toxic metabolite and enhances the formation of a desired metabolite (e.g. Nevirapine: A. M. Sharma et al., Chem. Res. Toxicol., 2013, 26, 410; Efavirenz: A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102; both incorporated herein by reference). In other cases, the major effect of deuteration is to reduce the rate of systemic clearance. As a result, the biological half-life of the compound is increased. The potential clinical benefits would include the ability to maintain similar systemic exposure with decreased peak levels and increased trough levels. This could result in lower side effects and enhanced efficacy, depending on the particular compound's pharmacokinetic / pharmacodynamic relationship. ML-337 (C. J. Wenthur et al., J. Med. Chem., 2013, 56, 5208) and Odanacatib (K. Kassahun et al., WO2012 / 112363) are examples for this deuterium effect. Still other cases have been reported in which reduced rates of metabolism result in an increase in exposure of the drug without changing the rate of systemic clearance (e.g. Rofecoxib: F. Schneider et al., Arzneim. Forsch. / Drug. Res., 2006, 56, 295; Telaprevir: F. Maltais et al., J. Med. Chem., 2009, 52, 7993; incorporated herein by reference). Deuterated drugs showing this effect may have reduced dosing requirements (e.g. lower number of doses or lower dosage to achieve the desired effect) and / or may produce lower metabolite loads.
[0088] A compound of general formula (I) may have multiple potential sites of attack for metabolism. To optimize the above-described effects on physicochemical properties and metabolic profile, deuterium-containing compounds of general formula (I) having a certain pattern of one or more deuterium-hydrogen exchange(s) can be selected. Particularly, the deuterium atom(s) of deuterium-containing compound(s) of general formula (I) is / are attached to a carbon atom and / or is / are located at those positions of the compound of general formula (I), which are sites of attack for metabolizing enzymes such as e.g. cytochrome P 450 . Optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example, by the formation of diastereoisomeric salts using an optically active acid or base or formation of covalent diastereomers. Examples of appropriate acids are tartaric, diacetyltartaric, ditoluoyltartaric and camphorsulfonic acid. Mixtures of diastereoisomers can be separated into their individual diastereomers on the basis of their physical and / or chemical differences by methods known in the art, for example, by chromatography or fractional crystallisation. The optically active bases or acids are then liberated from the separated diastereomeric salts. A different process for separation of optical isomers involves the use of chiral chromatography (e.g., chiral HPLC columns), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable chiral HPLC columns are manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ among many others, all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of this invention can likewise be obtained by chiral syntheses utilizing optically active starting materials.

[0273] Methods of testing for a particular pharmacological or pharmaceutical property are well known to persons skilled in the art.
[0274] The example testing experiments described herein serve to illustrate the present invention and the invention is not limited to the examples given.Synthesis of compounds of general formula (I) of the present invention
[0275] Compounds of general formula (I) with the meaning of R 1< , R 2< , R 3< , R 5< , R 6< and R 7< as defined in general formula (I), can be synthesised according to various general procedures.
[0276] Scheme 1 depicts the synthesis starting from synthons of the formula (II), wherein Hal stands for Cl, Br or I, Br being preferred; and wherein ALK stands for C 1 -C 5 -alkyl, methyl, ethyl and propyl being preferred). The aryl halides of the general formula (II) can be cross-coupled with boronic acids of the general formula (III) or alternatively with their respective pinacol esters to yield compounds of general formula (IV) by Pd-mediated reactions (Suzuki coupling) known to those skilled in the art. A suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane and optionally water) is used and a base (such as triethylamine, potassium carbonate, caesium carbonate) and a catalyst-ligand mixture, for example of palladium(II) acetate / triphenylphosphine, tetrakis-(triphenylphosphine)palladium(0), bis(triphenylphosphine)palladium(II) dichloride, bis(diphenylphosphino)ferrocenedichloropalladium (II) is utilised at temperatures between 20 °C and 120 °C, preferred at 100 °C.
[0277] Aromatic amines of general formula (IV) may react with carboxylic acids of general formula (V) by methods known to those skilled in the art to give the amide compounds of general formula (VI). The reaction is mediated by activating a carboxylic acid of general formula (V) with reagents such as dicyclohexylcarbodiimide (DCC), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDCI), N-hydroxybenzotriazole (HOBT), N-[(dimethylamino)-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yloxy)methyliden]-N-methylmethanaminium hexafluorophosphate (HATU) or propylphosphonic anhydride (T3P). For example, the reaction with HATU takes place in an inert solvent, such as N,N-dimethylformamide, dichloromethane or dimethyl sulfoxide in the presence of the appropriate aniline of general formula (IV) and a tertiary amine (such as triethylamine or diisopropylethylamine) at temperatures between -30 °C and +60 °C.
[0278] It is also possible to convert a carboxylic acid of the general formula (V) into the corresponding carboxylic acid chloride with an inorganic acid chloride (such as phosphorus pentachloride, phosphorus trichloride or thionyl chloride) and then into the amide compounds of general formula (VI), in pyridine or a solvent (such as dichloromethane, or N,N-dimethylformamide), in the presence of the appropriate amine formula (IV) and a tertiary amine (for example triethylamine) at temperatures between -30 °C and +60 °C. The ester moiety of compounds of general formula (VI) are then converted to the final target compounds of general formula (I) by ester group saponification in a solvent (such as tetrahydrofuran, methanol or N,N-dimethylformamide) using an appropriate base (for example aqueous lithium hydroxide or aqueous sodium hydroxide) at temperatures between 0 °C and +80 °C. Alternatively, the ester compounds of general formula (VI) can be converted to the final target compounds of general formula (I) by ester group saponification using an appropriate inorganic acid (for example hydrochloric acid or sulfuric acid) at temperatures between 0 °C and +80 °C, usually at circa +60 °C.
[0279] Aryl halides of the general formula (II) are either commercially available or can be synthesised by those skilled in the art from the corresponding carboxylic acid compound. For example, by reacting the corresponding carboxylic acid with an alcohol (such as methanol, ethanol or propanol) in inorganic acid (for example hydrochloric acid or sulfuric acid) at temperatures between 0 °C and 100 °C.
[0280] The starting materials of the general formula (II) are either commercially available or can be synthesized via methods known to those skilled in the art from appropriate precursors. For example, the amino group may be obtained by reduction of the corresponding nitro group with hydrogen in the presence of a palladium catalyst in solvents like ethanol, ethyl acetate or mixtures thereof. Alternatively, the nitro group may be reduced using iron powder in solvents like methanol or ethanol in the presence of acid (such as hydrochloric or acetic acid). The nitro group may be introduced by classical methods like treatment with nitric acid / sulphuric acid or potassium nitrate / sulphuric acid (with appropriate concentration and volume ratio) at temperatures between 0 °C and 25 °C. The sequence of reaction steps (nitro reduction, Suzuki reaction, amide formation, nitrile hydrolysis) may be changed as appropriate.
[0281] The carboxylic acids of the general formula (V) are either commercially available or can be synthesized via methods known to those skilled in the art from appropriate precursors. For example, arylcyclopropanecarboxylic acids may be prepared from the corresponding arylacetonitrile by cyclopropanation with 1-bromo-2-chloroethane (1.5 eq) in aqueous base (such as sodium hydroxide solution) in the presence of benzyltriethylammonium chloride (0.02 eq.) and subsequent acidic or basic hydrolysis of the nitrile with e.g. lithium hydroxide in water or concentrated hydrochloric acid at temperatures between 20 °C and 100 °C.
[0282] Scheme 2 depicts the synthesis starting from synthons of the formula (VII), wherein Hal stands for Cl, Br or I, Br being preferred. The aryl halides of the general formula (VII) can be cross-coupled with boronic acids of the general formula (III) or alternatively with their respective pinacol esters to yield compounds of general formula (VIII) by Pd-mediated reactions (Suzuki coupling) known to those skilled in the art. A suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane and optionally water) is used and a base (such as potassium carbonate or caesium carbonate) and a catalyst-ligand mixture, for example of palladium(II) acetate / triphenylphosphine, tetrakis(triphenylphosphine)palladium(0), bis(triphenylphosphine)-palladium(II) dichloride, bis(diphenylphosphino)ferrocenedichloropalladium (II) is utilised at temperatures between 20 °C and 120 °C, preferred at 100 °C. The nitro group of a compound of general formula (VIII) is then reduced to the corresponding aniline of general formula (IX) by reaction under a hydrogen atmosphere in the presence of a palladium catalyst (for example 5-10% palladium on carbon) in an appropriate solvent (for example ethanol or ethyl acetate) at temperatures between 0 °C and 100 °C. In analogy to the procedures described for Scheme 1, amide coupling gives compounds of the general formula (X). The nitrile moiety of formula (X) is hydrolysed to carboxylic acid of general formula (I) by reaction with either an inorganic base (for example aqueous lithium hydroxide or aqueous sodium hydroxide) or an inorganic acid (for example hydrochloric acid or sulfuric acid) optionally in an inert solvent (such as tetrahydrofuran, 1,4-dioxane or N,N-dimethylformamide) at temperatures between 10 °C and 100 °C.
[0283] Scheme 3 shows an alternative approach in which the sequence of reaction steps is changed and the nitrile moiety of general formula (IX) is transformed into an ester group in two steps (wherein ALK stands for methyl, ethyl or propyl) and later revealed as the carboxylic acid group. Starting from synthons of general formula (IX), first the nitrile is converted into the carboxylic acid of general formula (XI) and then reacted with a suitable alcohol (such as methanol, ethanol or propanol) in inorganic acid (for example hydrochloric acid or sulfuric acid) at temperatures between 0 °C and 100 °C to form ester compounds of general formula (IV). In analogy to the procedures described for Scheme 1, amide coupling gives compounds of the general formula (VI), followed by ester group saponification to yield the target compounds of general formula (I).
[0284] Scheme 4 shows an alternative approach to synthesis of compounds of general formula (I) where R 1< is an N-linked optionally substituted 5-membered heteroaryl group, for example pyrazolyl or imidazolyl, or alternatively R 1< is an N-linked optionally substituted bicyclic 8- to 10-membered heteroaryl group, for example indole. Starting from synthons of the general formula (VII) (wherein Hal stands for F, Cl or Br) the aryl halide can first be substituted by a nucleophile of general formula (XIV) to yield a compound of general formula (VIII). The substitution takes place in a dipolar aprotic solvent such as acetonitrile, dimethylsulfoxide or N,N-dimethylformamide and in the presence of an appropriate base (for example potassium carbonate or sodium hydride) at temperatures between 20 °C and 100 °C, preferably at 60 °C. In analogy to the procedures described for Scheme 2, nitro group reduction followed by amide formation gives compounds of general formula (X) that are subsequently converted to the final targets of general formula (I) by nitrile group hydrolysis.
[0285] In Scheme 4 general formula (XIV) represents R 1< -H wherein R 1< is an optionally substituted 5-membered heteroaryl group linked through a ring nitrogen atom to the hydrogen atom, or R 1< is an optionally substituted bicyclic 8- to 10-membered heteroaryl linked through a ring nitrogen atom to the hydrogen atom.
[0286] Scheme 5 shows an alternative approach to synthesis compounds of general formula (I) where R 1< is an N-linked optionally substituted 5-membered heteroaryl group, for example pyrazolyl or imidazolyl, or alternatively R 1< is an N-linked optionally substituted bicyclic 8- to 10-membered heteroaryl group, for example indole. Starting from synthons of the general formula (XII) (wherein Hal stands for F, Cl or Br; and wherein ALK stands for methyl, ethyl or propyl), the aryl halide can first be substituted by a nucleophile of general formula (XIV) to yield a compound of general formula (XIII). The substitution takes place in a dipolar aprotic solvent such as acetonitrile, dimethylsulfoxide or N,N-dimethylformamide and in the presence of an appropriate base (for example potassium carbonate or sodium hydride) at temperatures between 20 °C and 100 °C, preferably at 60 °C. In analogy to the procedures described for Scheme 2, nitro reduction gives compounds of general formula (IV), followed by amide coupling gives compounds of the general formula (VI), followed by ester group saponification to yield the target compounds of general formula (I).
[0287] In Scheme 5 general formula (XIV) represents R 1< -H wherein R 1< is an optionally substituted 5-membered heteroaryl group linked through a ring nitrogen atom to the hydrogen atom, or R 1< is an optionally substituted bicyclic 8- to 10-membered heteroaryl linked through a ring nitrogen atom to the hydrogen atom.
[0288] Scheme 6 depicts the synthesis starting from synthons of the formula (XV), wherein Hal stands for Br or I, Br being preferred. The aryl halides of the general formula (XV) can be cross-coupled with boronic acids of the general formula (III) or alternatively with their respective pinacol esters to yield compounds of general formula (XVI) by Pd-mediated reactions (Suzuki coupling) known to those skilled in the art. A suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane and optionally water) is used and a base (such as triethylamine, potassium carbonate, caesium carbonate) and a catalyst-ligand mixture, for example of palladium(II) acetate / triphenylphosphine, tetrakis-(triphenylphosphine)palladium(0), bis(triphenylphosphine)-palladium(II) dichloride, bis(diphenylphosphino)ferrocenedichloropalladium (II) is utilised at temperatures between 20 °C and 120 °C, preferred at 100 °C. The chloro group of a compound of general formula (XVI) is converted to a nitrile group to yield compounds of general formula (IX), by Pd-mediated cyanation reactions with potassium ferrocyanide known to those skilled in the art. A suitable solvent mixture (for example 1,4-dioxane or tetrahydrofuran and optionally water) is used and a base (such as potassium acetate) and a catalyst-ligand mixture (for example tris[dibenzylideneacetone]dipalladium / dicyclohexyl[2',4',6'-tri(propan-2-yl)biphenyl-2-yl]phosphane) is utilised at temperatures between 20 °C and 120 °C, usually 100 °C. In analogy to the procedures described for Scheme 3, the nitrile moiety of general formula (IX) is converted into the carboxylic acid of general formula (XI) and then reacted with a suitable alcohol (such as methanol, ethanol or propanol; wherein ALK stands for methyl, ethyl or propyl) in inorganic acid (for example hydrochloric acid or sulfuric acid) at temperatures between 0 °C and 100 °C to form ester compounds of general formula (IV). In analogy to the procedures described for Scheme 1, amide coupling gives compounds of the general formula (VI), followed by ester group saponification to yield the target compounds of general formula (I). The sequence of reaction steps (nitrile hydrolysis, amide formation) may be changed as appropriate. In analogy with Scheme 2, final compounds of general formula (I) can be accessed directly via nitrile group hydrolysis carried out as a final transformation.
[0289] Scheme 7 shows an alternative approach to synthesis of compounds of general formula (I) with the meaning of R 1< , R 2< , X and R 3< as defined in general formula (I). The aryl group of general formula (XVII) can be nitrated by reaction with a mixture of nitric acid and sulfuric acid at temperatures between -20 °C and +20 °C, preferred below +10 °C. The carboxylic acid group of a compound of general formula (XVIII) is reacted with a suitable alcohol (such as methanol, ethanol or propanol; wherein ALK stands for methyl, ethyl or propyl) in inorganic acid (for example hydrochloric acid or sulfuric acid) at temperatures between 0 °C and 100 °C to form ester compounds of general formula (XIX). The hydroxy group of a compound of general formula (XIX) is converted to a triflate group to yield compounds of general formula (XX), by reaction with trifluoromethanesulfonic anhydride in base (for example triethylamine) and an inert solvent (such as dichloromethane) at temperatures between -20 °C and + 40 °C, usually at 0 °C. The aryl triflates of the general formula (XX) can be cross-coupled with boronic acids of general formula (III) or alternatively with their respective pinacol esters to yield compounds of general formula (XIII), by Pd-mediated reactions (Suzuki coupling) known to those skilled in the art. A suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane and optionally water) is used and a base (such as triethylamine, potassium carbonate, caesium carbonate) and a catalyst-ligand mixture, for example of palladium(II) acetate / triphenylphosphine, tetrakis(triphenylphosphine)palladium(0), bis(triphenylphosphine)-palladium(II) dichloride, bis(diphenylphosphino)ferrocene-dichloropalladium (II) is utilised at temperatures between 20 °C and 120 °C, preferred at 100 °C. In analogy to the procedures described for Scheme 2, nitro group reduction followed by amide formation gives compounds of general formula (VI) that are subsequently converted to the final targets of general formula (I) by ester group hydrolysis as detailed in Scheme 1.
[0290] Scheme 8 shows an alternative approach to synthesis of compounds of general formula (I). Starting from synthons of general formula (XXI), the aniline can first be protected using a combination of two equivalents of a strong base (such as nBuLi) and 1,2-bis(chlorodimethylsilyl)ethane. The intermediate obtained can then be lithiated in situ using nBuLi and then quenched with an alkylchloroformate (such as ethylchloroformate). Subsequent treatment with an inorganic aqueous acid (such as hydrochloric acid) gives compounds of general formula (XXII) wherein ALK stands for methyl, ethyl or propyl. In analogy to the procedures described for Scheme 1, Suzuki coupling followed by amide coupling gives compounds of the general formula (VI). Subsequent ester group saponification yields the target compounds of general formula (I).
[0291] Scheme 9 shows an alternative approach to synthesis of compounds of general formula (I) in which the sequence of reaction steps is changed in comparison to Scheme 1, wherein Hal stands for Cl, Br or I, Br being preferred; and wherein ALK stands for methyl, ethyl or propyl. Starting from synthons of the general formula (II), the aromatic amine may react with carboxylic acids of general formula (V) by methods known to those skilled in the art to give the amide compounds of general formula (XXIII). The reaction is mediated by activating a carboxylic acid of general formula (V) with reagents such as dicyclohexylcarbodiimide (DCC), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDCI), N-hydroxybenzotriazole (HOBT), N-[(di-methylamino)-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yloxy)methyliden]-N-methyl-methanaminium hexafluorophosphate (HATU) or propylphosphonic anhydride (T3P). For example, the reaction with T3P takes place in an inert solvent, such as N,N-dimethylformamide or dichloromethane in the presence of the appropriate aniline general formula (II) and a tertiary amine (such as triethylamine or diisopropylethylamine) at temperatures between -30 °C and +60 °C.
[0292] The aryl halides of the general formula (XXIII) can be cross-coupled with boronic acids of the general formula (III) or alternatively with their respective pinacol esters to yield compounds of general formula (VI) by Pd-mediated reactions (Suzuki coupling) known to those skilled in the art. A suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane and optionally water) is used and a base (such as potassium carbonate or caesium carbonate) and a catalyst-ligand mixture, for example of palladium(II) acetate / triphenylphosphine, tetrakis(triphenylphosphine)palladium(0), bis(triphenylphosphine)palladium(II) dichloride, bis(diphenylphosphino)ferrocenedichloro-palladium (II) is utilised at temperatures between 20 °C and 120 °C, preferred at 100 °C. In analogy to the procedures described for Scheme 1, ester group saponification of an intermediate compound of general formula (VI) yields the target compounds of general formula (I).
[0293] Scheme 10 shows an alternative approach to synthesis of compounds of general formula (I). Alkylation of 2-acetylbutyrolactones of general formula (XXIV) can be achieved with an alkylating agent of general formula (XXV) wherein X stands for Cl, Br or I, Br being preferred in the presence of a base (such as potassium carbonate or sodium carbonate) in an apolar solvent (such as acetonitrile or tetrahydrofuran) at a temperature between 20 °C and 60 °C. Subsequent rearrangement of compounds of general formula (XXVI) to give cyclopropanes of general formula (XXVII) can be achieved via reaction with lithium iodide in a polar solvent (such as dimethylformamide or 1-methyl-2-pyrrolidinone) at temperatures between 100 °C and 200 °C. Carboxylic acids of general formula (V) can then be formed via reaction of compounds of general formula (XXVII) with bromine or iodine in the presence of a sodium hydroxide in a solvent (such as tetrahydrofuran or 1,4-dioxane) at temperatures between 0 °C to 20 °C. In analogy to the procedures described for Scheme 1, amide coupling gives compounds of the general formula (VI). Subsequent ester group saponification yields the target compounds of general formula (I).
[0294] Scheme 11 shows an alternative approach to synthesis of compounds of general formula (I). Starting from synthons of the general formula (XII) (wherein Hal stands for Cl, Br or I; and wherein ALK stands for methyl, ethyl or propyl) the aryl halide can first be converted to a stannane of general formula (XXVIII) via reaction with hexabutyldistannane in the presence of a palladium catalyst (such as tetrakis-(triphenylphosphine)palladium(0), bis(triphenylphosphine)-palladium(II) dichloride) in a suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane or 1,2-dimethoxyethane) at temperatures between 20 °C and 120 °C, preferred at 100 °C. The aryl stannane of the general formula (XXVIII) can then be cross-coupled with aryl halides of the general formula (XXIX), with the meaning of R 1< as defined in general formula (I), by Pd-mediated reactions (Stille coupling) known to those skilled in the art. A suitable solvent (for example N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane or 1,2-dimethoxyethane) is used with a catalyst-ligand mixture, for example of palladium(II) acetate / triphenylphosphine, tetrakis(triphenylphosphine)palladium(0), bis(triphenylphosphine)-palladium(II) dichloride, bis(diphenylphosphino)ferrocenedichloropalladium (II) is utilised at temperatures between 20 °C and 120 °C, preferred at 100 °C. In analogy to the procedures described for Scheme 1, nitro reduction gives compounds of general formula (IV), followed by amide coupling gives compounds of the general formula (VI), followed by ester group saponification to yield the target compounds of general formula (I).
