AI Technical Summary
Current treatments for cardiovascular and kidney diseases, particularly those involving autonomic imbalance, lack effective and safe therapeutic options, especially for patients with comorbidities like diabetes and heart failure, where autonomic dysfunction contributes to increased morbidity and mortality.
Development of new 7-substituted 1-aryl-naphthyridine-3-carboxamides as potent positive allosteric modulators of the muscarinic M2 receptor to enhance parasympathetic activity, offering a potential therapeutic approach by modulating receptor conformations and improving cardiovascular and renal function.
These compounds provide a promising therapeutic strategy for treating and preventing cardiovascular and kidney diseases by enhancing parasympathetic activity, reducing inflammation, and improving mitochondrial function, potentially leading to improved patient outcomes and reduced side effects.
Description
[0001] The present application relates to new 7-substituted 1-aryl-naphthyridine-3-carboxamides, processes for their production, their use alone or in combinations for the treatment and / or prevention of diseases and their use for the production of medicaments for the treatment and / or prevention of diseases, in particular for the treatment and / or prevention of cardiovascular diseases and / or kidney diseases.
[0002] Muscarinergic receptors are membrane-based receptors that bind the neurotransmitter acetylcholine (ACh) as an endogenous ligand (acetylcholine receptors), but can also be activated by muscarin. These G protein-coupled receptors exist as five subtypes (M1-M5) that are expressed in almost all tissues in the human organism. They are found in both the central and peripheral nervous systems as well as in many organs of the autonomic nervous system.
[0003] The M2 type (M2R) is predominantly expressed in the heart. At the cellular level, M2R stimulation by the agonist acetylcholine causes an inhibition of adenyl cyclase and an activation of the inwardly rectifying potassium channel (IKACh channel, GIRK: G protein activated inwardly rectifying K+ channel; also Kir3.x). This increases the potassium conductivity, which leads to hyperpolarization of the muscle cells. Accordingly, the cells become more difficult to depolarize, which leads to a negative chronotropic and dromotropic effect, so that the heart rate decreases. The M2R is the main mediator of the parasympathetic control of cardiac function, which is controlled by the vagus nerve. The right vagus nerve reduces the heart rate via the sinoatrial node, while the left predominantly increases the atrioventricular conduction time via the atrioventricular node (AV node). Overall, the influence of the vagus on the resting frequency of the heart predominates compared to the sympathetic nervous system. The effects of stimulation of M2R are therefore opposite to those of beta-adrenergic stimulation.
[0004] The activation of the M2 receptor by the endogenous agonist acetylcholine, but also by synthetic analogues such as carbachol, oxotremorin-M or Iperoxo (Schrage et al., Biochem. Pharmacol. 2014, 90(3), 307-319) occurs through the binding of the agonist to the so-called orthosteric binding site of the receptor and a resulting conformational change of the receptor or stabilization of the active receptor conformation. In addition to the endogenous agonist acetylcholine (ACh), the classic naturally occurring muscarinic receptor agonists include various plant alkaloids such as arecoline, muscarine and pilocarpine (Neubig et al., Pharmacol Rev., 2003, 55, 597-606). The orthosteric binding site of all muscarinic acetylcholine receptors is highly evolutionarily conserved and shows a high sequence and structural homology between the different subtypes. Therefore, many of the known agonists are nonselective towards the different subtypes of muscarinic acetylcholine receptors (Kruse et al., Mol Pharmacol., 2013, 84(4), 528-540). The M2R has an orthosteric as well as an allosteric binding site (Gregory et al., Current Neuropharmacol., 2007, 5(3), 157-167). The oldest known allosteric modulator is gallamine (Clark and Mitchelson, Br. J. Pharmac., 1976, 58, 323-331).
[0005] Allosteric modulators have clear differences compared to classic, orthosteric ligands. The allosteric modulator itself has no direct influence on receptor activation. The binding of the alloster results in a modulation of the binding affinity and / or effectiveness of the orthosteric agonist. The effect of an allosteric modulator can only develop in the presence of the endogenous ligand. This results in a spatial and temporal specificity of the allosteric effect (Conn et al., Nat. Rev. Drug Disc., 2009, 8, 41-54; Conn et al, Nat. Rev. Drug. Disc., 2014, 13, 692-708). Furthermore, the effect of an allosteric modulator is self-limiting if it stabilizes the binding of the agonist at high concentrations. This in turn generally results in a more favorable safety pharmacological profile compared to agonists, since toxic effects are limited due to receptor overactivation (Christopoulos, Mol. Pharmacol., 2014, 86, 463-478).
[0006] The mutual influence of allosteric and orthosteric ligands in terms of affinity and intrinsic activity, known as cooperativity, is determined by both ligands. In the case of a positive allosteric modulator of the M2R, the effects of the ACh (orthosteric ligand) are enhanced (positive cooperativity). Due to their ability to modulate receptor conformations in the presence of an orthosteric ligand, allosteric ligands can produce fine-tuning pharmacological effects (Wang et al., J. Pharmacol. Exp. Therap., 2009, 331, 340-348). In the case of the positive allosteric modulator of M2R, this can be expected to have an advantageous effect profile, a reduced risk of side effects and a starting point for the development of subtype-selective ligands compared to a full agonist.
[0007] From the positive allosteric M4R and M2R ligand LY2119620 (3-amino-5-chloro- N -cyclopropyl-4-methyl-6-[2-(4-methylpiperazin-1-yl)-2-oxoethoxy]thieno[2,3-b]pyridine-2-carboxamide), the crystal structure in complex with the M2R was published. The allosteric binding site of the M2R is spatially adjacent to, but clearly demarcated from, the orthosteric binding site and, in comparison to the other muscarinic receptor subtypes, shows less conservation or has larger sequence differences (Kruse et al., Nature, 2013, 504, 101- 106). LY2119620 has been described as a nonselective M2R / M4R positive allosteric modulator (Croy et al., Molecular Pharmacology, July 2014 86, 1, 106-115; Schober et al., Molecular Pharmacology, July 2014 86, 1, 116-123).
[0008] As a component of the autonomic nervous system, the M2R plays an important role in the pathogenesis and progression of cardiovascular diseases. Autonomic imbalance characterized by vagal (parasympathetic) attenuation and a dominance of the sympathetic nervous system is closely associated with increased morbidity and mortality. The clinical and prognostic significance of autonomic imbalance is well documented in various cardiovascular diseases, including heart failure (HF), cardiac arrhythmias, ischemia / reperfusion (I / R), hypertension (He et al., Br. J. Pharmacol. 2014 , Epub) and chronic kidney disease (Ranpuria et al., Nephrol Dial Transplant. 2008, 23(2), 444-4499). Particularly in patients with comorbidities such as diabetes, autonomic imbalance can contribute to increased morbidity and mortality (Vinik et al., Diabet Med., 2011, 28(6), 643-651). Baroreceptor reflex dysfunction, such as hypertensive crises or hypertension variability, as signs of autonomic nervous system dysfunction, often accompany the acute phase of ischemic or hemorrhagic stroke (Sykora et al., Stroke, 2009, 40(12), 678-682 ).
[0009] The often observed comorbidity between cardiovascular and mental illnesses, such as between heart failure and depression, is probably based on common pathomechanisms associated with autonomic imbalance (Halaris et al., Mod Trends Pharmacopsychiatri., 2013, 28, 144-161). Chronic stress shifts the homeostatic balance of the autonomic nervous system. Decreased vagal tone contributes to a pro-inflammatory status, with impaired neurotransmitter regulation, particularly serotonergic transmission. Other mental illnesses have also been associated with autonomic dysregulation, such as attention-deficit / hyperactivity disorder (ADHD), which is characterized by disinhibition, poor emotional self-control, inattention, and hyperactivity (Rash and Aguirre-Camacho, Atten Defic Hyperact Disord., 2012, 4(4), 167-177).
[0010] A strengthening of parasympathetic activity through a positive allosteric modulator including expected anti-inflammatory effects, increase in nitric oxide (NO), regulation of the redox state, improvement of mitochondrial function and calcium regulation could therefore represent a new therapeutic principle, especially in cardiovascular diseases. There is ample evidence that modulation of parasympathetic activity can be considered as a potential therapeutic target in chronic heart failure. Vagus nerve stimulation in dogs with healed myocardial infarction was able to significantly reduce the incidence of sudden cardiac death and mortality in chronic heart failure rats (De Ferrari, J. Cardiovasc. Transl. Res., 2014, 7(3), 310-320). In a dog model with heart failure (LVEF 35%) and an implanted vagal stimulator, it was demonstrated that the therapy group experienced a significant improvement in left ventricular ejection fraction (LVEF) and reduction in end-systolic and end-diastolic volumes (LVESV; LVEDV) compared to the sham group as well as a significant reduction in heart rate within 3 months. The described effect of VNS was additive to the administration of beta blockers (De Ferrari, J. Cardiovasc. Transl. Res., 2014, 7(3), 310-320). The plasma levels of TNF-α and IL-6 as well as their myocardial protein expression could be reduced by vagal stimulation in this animal model, which suggests that strengthening the parasympathetic nervous system has positive effects on pro-inflammatory cytokines in addition to the effects on LV remodeling.
[0011] Based on the experimental preclinical data, the first clinical studies on vagal stimulation in patients with chronic heart failure, as already established in the treatment of epilepsy and depression, have now been carried out. The effect of parasympathetic enhancement via direct vagus nerve stimulation (VNS) was evaluated in a non-randomized observational study of 32 patients with left ventricular (LV) systolic dysfunction, with results indicating that vagal stimulation improved quality of life, exercise tolerance, and LV function. Remodeling favorably influenced (De Ferrari GM et al., Eur. Heart J., 2011, 32, 847-855) In the multicenter open-label feasibility study ANTHEM-HF, the safety, tolerability and effectiveness of vagal stimulation in patients with chronic stable, symptomatic heart failure with reduced ejection fraction (HFrEF) in addition to standard therapy (Premchand RK et al., J. Card. Fail., 2014, 20(11), 808-816). Continuous vagal nerve stimulation used in this study resulted in improvements in ejection fraction, heart rate variability, NYHA class, and quality of life. The first placebo-controlled clinical study NECTAR-HF, however, was unable to show any significant effect of vagus nerve stimulation on the cardiac function of HF patients after 6 months (Zannad et al., Eur. Heart J., 2015, 36(7), 425-433) . Only the quality of life could be improved. The INOVATE-HF study with 650 HF patients was unable to show any effects of this therapy in terms of mortality and hospitalization. (Gold et al., J Am Coll Cardiol., 2016, Mar 29. pii: S0735-1097(16)32404-4. doi: 10.1016 / j.jacc.2016.03.525). Quality of life and walking distance were significantly improved.
[0012] In addition to the risk of infection and the potential risks of a surgical procedure, therapy using electrical stimulation of the vagus nerve is limited by side effects such as: dysphonia, cough and mouth / throat pain (Premchand RK et al., J. Card. Fail., 2014, 20(11 ), 808-816). Drug strengthening of the parasympathetic nervous system through a direct effect on the M2R could represent a new therapeutic option.
[0013] Atrial fibrillation is the most common persistent cardiac arrhythmia and its prevalence increases with age (Chen et al., Circ. Res., 2014, 114(9), 1500-1515). Atrial fibrillation and heart failure are often associated and reinforce each other. The prevalence of atrial fibrillation increases with the clinical severity of heart failure (Maisel and Stevenson, Am. J. Cardiol., 2003, 91, (suppl) 2D-8D). Clinical data suggest that patients in whom heart failure is accompanied by atrial fibrillation have a poor prognosis. Both mortality (overall mortality, sudden death and pump failure) and morbidity (hospitalization) were found to be significantly increased in this patient group.
[0014] When treating atrial fibrillation, a distinction is made between two treatment strategies: the so-called frequency control with adjustment and, if possible, normalization of the ventricular frequency in the context of atrial fibrillation, and the so-called rhythm control, which includes measures with which a sinus rhythm is to be established or maintained. An effective treatment consists of a combination of non-drug as well as drug or interventional measures (Levalter T, Advanced Training Program Pharmacy, 2011, 5, 106-127).
[0015] Beta blockers, class I and class III antiarrhythmics are used to control the rhythm with medication after cardioversion, depending on the underlying cardiac disease and the extent of the left ventricular pump function impairment. In patients with permanent atrial fibrillation as well as in oligosymptomatic (often older) patients with persistent or paroxysmal atrial fibrillation, pure frequency control while maintaining and leaving atrial fibrillation is often the treatment of choice. Medications that have an influence on the refractory period or the conduction capacity of the AV node are primarily used. In principle, this effect could be achieved by stimulating the M2R, which physiologically plays the key role at this point, e.g. with the help of a positive allosteric modulator. So far, beta blockers, digitalis, calcium antagonists and, in individual cases, amiodarone are available, which are used on an individual basis, taking into account the lifestyle, the underlying cardiac disease or any accompanying diseases. However, the options for drug therapy are inadequate, particularly in patients with reduced left ventricular pump function and severe heart failure. Calcium antagonists are contraindicated in this patient group. Digoxin therapy leads to increased mortality in patients with atrial fibrillation, as recent studies have shown (Leong-Sit and Tang, Curr. Opin. Cardiol., 2015 , EPub). A meta-analysis reported a lack of effectiveness for beta-blockers in patients with atrial fibrillation and heart failure (Leong-Sit and Tang, Curr. Opin. Cardiol., 2015 , EPub). The medical need for new, efficient and safe therapies for frequency control is correspondingly high. This could be achieved through drug stimulation of the M2R.
[0016] The object of the present invention is to identify and provide new substances which are potent, positive allosteric modulators of the muscarinic M2 receptor and as such are suitable for the treatment and / or prevention of, in particular, cardiovascular diseases and / or kidney diseases.
[0017] 1-Benzyl-substituted 4-oxo-1,4-dihydroquinolines-3-carboxylic acids are described as allosteric modulators of the M1 muscarinic receptor for the treatment of neurodegenerative diseases such as Alzheimer's and schizophrenia (Scammells et al., ACS Chem. Neurosci., 2013, 4 (7), 1026-1048; Mistry et al., J. Med. Chem. 2013, 56, 5151-5172). Pyridonecarboxylic acid derivatives which have antibacterial activity are known from EP 0945435 B1, among others. WO 2002 / 085886-A2, WO 2003 / 050107-A1 and WO 2005 / 026145-A2 describe 7-piperidino-substituted quinolone carboxylic acid derivatives, as well as various 7-pyrrolide in WO 2005 / 026165-A1 and WO 2005 / 049602-A1 ino -substituted quinolone carboxylic acid derivatives and in EP 1650192-A1 special 7-azetidinyl quinolone carboxylic acid derivatives with antimicrobial / antibacterial activity are claimed. Quinolone derivatives which can be used as platelet aggregation inhibitors are known from WO 2005 / 009971-A1 and JP 2005012561. In WO 2015 / 189560-A1, 1,4-dihydroquinoline derivatives are disclosed as NPRC agonists for the treatment of cardiovascular diseases. Quinolone carboxylic acid derivatives as MCT modulators are described in WO 2016 / 081464-A1 for the treatment of tumor diseases and inflammatory processes in particular.

[0020] Compounds according to the invention are also N -Oxides of the compounds of formula (I) and their salts, solvates and solvates of the salts.
[0021] In the context of the present invention, physiologically harmless salts of the compounds according to the invention are preferred as salts. Also included are salts that are not suitable for pharmaceutical applications themselves, but can be used, for example, for the isolation, purification or storage of the compounds according to the invention.
[0022] A suitable pharmaceutically acceptable salt of the compounds of the present invention may be, for example, an acid addition salt of a compound of the present invention having a sufficiently basic nitrogen atom in a chain or ring, such as an acid addition salt with an inorganic acid or "mineral acid", for example hydrochloric acid , hydrobromic acid, hydroiodic acid, sulfuric acid, sulfamic acid, disulfuric acid, phosphoric acid or nitric acid, or with an organic acid, such as formic acid, acetic acid, acetoacetic acid, pyruvic acid, trifluoroacetic acid, propionic acid, butyric acid, hexanoic acid, heptanoic acid, undecanoic acid, lauric acid, benzoic acid, salicylic acid, 2 -(4-Hydroxybenzoyl)benzoic acid, camphoric acid, cinnamic acid, cyclopentanepropionic acid, digluconic acid, 3-hydroxy-2-naphthoic acid, nicotinic acid, pamoic acid, pectic acid, 3-phenylpropionic acid, pivalic acid, 2-hydroxyethanesulfonic acid, itaconic acid, trifluoromethanesulfonic acid, dodecylsulfuric acid, ethanesulf onic acid, benzenesulfonic acid, para-toluenesulfonic acid, methanesulfonic acid, 2-naphthalenesulfonic acid, naphthalene disulfonic acid, camphorsulfonic acid, citric acid, tartaric acid, stearic acid, lactic acid, oxalic acid, malonic acid, succinic acid, malic acid, adipic acid, alginic acid, maleic acid, fumaric acid, D-gluconic acid, mandelic acid, ascorbic acid, glucoheptanoic acid, glycerophosphoric acid, Aspartic acid, sulfosalicylic acid or thiocyanic acid.

[0024] Furthermore, it is known to those skilled in the art that acid addition salts of the claimed compounds can be prepared by reacting the compounds with the corresponding inorganic or organic acid using a number of known methods. Alternatively, alkali metal and alkaline earth metal salts of the acidic compounds according to the invention are prepared by reacting the compounds according to the invention with the corresponding base using various known methods.
[0025] The present invention includes all possible salts of the compounds of the present invention as individual salts or as a mixture of these salts in any ratio.
[0026] When a compound is mentioned in the present text, especially in the experimental part, for the synthesis of intermediate products and examples of the present invention as a salt form with the corresponding base or acid, the exact stoichiometric composition of the salt form as determined by the respective preparation and / or or cleaning process was obtained is not known in most cases. Unless otherwise indicated, additions to chemical names or structural formulas that refer to salts, such as "hydrochloride", "trifluoroacetate", "sodium salt" or "x HCl", "x CF 3 COOH", "x Na +< " a salt form, although the stoichiometry of this salt is not specified. This applies accordingly to cases in which synthesis intermediates or example compounds or salts thereof were obtained as solvates, for example as hydrates, according to the production and / or purification process described.
[0027] In the context of the invention, solvates are those forms of the compounds according to the invention which form a complex in the solid or liquid state through coordination with solvent molecules. Hydrates are a special form of solvates that coordinate with water. Hydrates are preferred as solvates in the context of the present invention.
[0028] Depending on their structure, the compounds according to the invention can exist in different stereoisomeric forms, i.e. in the form of configurational isomers or optionally also as conformational isomers (enantiomers and / or diastereomers, including those in atropisomers). The present invention therefore encompasses the enantiomers and diastereomers as well as their respective mixtures. The stereoisomerically uniform components can be isolated in a known manner from such mixtures of enantiomers and / or diastereomers. Chromatographic methods are preferably used for this, in particular HPLC chromatography on achiral or chiral separation phases. In the case of carboxylic acids as intermediates or end products, a separation can alternatively be carried out via diastereomeric salts using chiral amine bases.
[0029] In the context of the present invention, the term “enantiomerically pure” is understood to mean that the compound in question is present in an enantiomeric excess of more than 95%, preferably more than 98%, with regard to the absolute configuration of the chiral centers. The enantiomeric excess enantiomeric excess, ee value) is calculated by evaluating the chromatogram of an HPLC analysis on a chiral phase using the following formula: ee = Enantiomer 1 Flächenprozent − Enantiomer 2 Flächenprozent Enantiomer 1 Flächenprozent − Enantiomer 2 Flächenprozent × 100 % .
[0030] To the extent that the compounds according to the invention can occur in tautomeric forms, the present invention encompasses all tautomeric forms.
[0031] The present invention also includes all suitable isotopic variants of the compounds according to the invention. An isotopic variant of a compound according to the invention is understood to mean a compound in which at least one atom within the compound according to the invention is opposed to another atom of the same atomic number, but with a different atomic mass than the atomic mass that usually or predominantly occurs in nature ("unnatural proportion") ) is replaced. The term “unnatural portion” means a portion of such an isotope that is higher than its natural abundance. The natural frequencies of isotopes to be used in this context can be found in "Isotopic Compositions of the Elements 1997", Pure Appl. Chem., 70(1), 217-235, 1998. Examples of isotopes that can be incorporated into a compound according to the invention are those of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, bromine and iodine, such as 2< H (deuterium), 3< H (tritium), 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, 129<I and 131<I. Certain isotopic variants of a compound according to the invention, in particular those in which one or more radioactive isotopes are incorporated, can be of use, for example, for studying the mechanism of action or the distribution of active ingredients in the body; Because they are comparatively easy to produce and detect, compounds marked with 3<H or 14<C isotopes are particularly suitable for this purpose. In addition, the incorporation of isotopes such as deuterium can lead to certain therapeutic benefits as a result of greater metabolic stability of the compound, such as an extension of the half-life in the body or a reduction in the required effective dose; Such modifications of the compounds according to the invention may therefore also represent a preferred embodiment of the present invention. With regard to the treatment and / or prophylaxis of the disorders specified here, the isotopic variant(s) of the compounds of the general formula (I) preferably contain deuterium ("deuterium-containing compounds of the general formula (I)"). Isotopic variants of the compounds of general formula (I), into which one or more radioactive isotopes, such as 3<H or 14<C, are incorporated, are useful, for example, in drug and / or substrate tissue distribution studies. These isotopes are particularly preferred because of their easy incorporation and detectability. Positron-emitting isotopes such as 18<F or 11<C can be incorporated into a compound of the general formula (I). These isotopic variants of the compounds of general formula (I) are suitable for use in in vivo imaging applications. Deuterium-containing and 13<C-containing compounds of the general formula (I) can be used in mass spectrometry analyzes in the context of preclinical or clinical studies (H. J. Leis et al., Curr. Org. Chem., 1998, 2, 131). Isotopic variants of the compounds according to the invention can be prepared using commonly used methods known to those skilled in the art, for example using the methods described below and the instructions given in the exemplary embodiments, by using corresponding isotopic modifications of the respective reagents and / or starting compounds. Isotopic variants of the compounds of general formula (I) can generally be prepared according to methods known to those skilled in the art, as described in the schemes and / or examples described here, by replacing a reagent with an isotopic variant of the reagent, preferably a deuterium-containing reagent. Depending on the desired deuteration sites, in some cases deuterium from D 2 O can be incorporated either directly into the compounds or into reagents that can be used for the synthesis of such compounds (Esaki et al., Tetrahedron, 2006, 62, 10954; Esaki et al., Chem. Eur. J., 2007, 13, 4052). Deuterium gas is also a useful reagent for incorporating deuterium into molecules. A rapid route to incorporation of deuterium is the catalytic deuteration of olefinic bonds (H. J. Leis et al., Curr. Org. Chem., 1998, 2, 131; J. R. Morandi et al., J. Org. Chem., 1969, 34 (6), 1889) and acetylenic bonds (N. H. Khan, J. Am. Chem. Soc., 1952, 74 (12), 3018; S. Chandrasekhar et al., Tetrahedron, 2011, 52, 3865). To directly exchange hydrogen for deuterium in functional group-containing hydrocarbons, metal catalysts (i.e., Pd, Pt, and Rh) can also be used in the presence of deuterium gas (J. G. Atkinson et al., U.S. Patent 3,966,781). Various deuterated reagents and synthesis building blocks are commercially available from companies such as C / D / N Isotopes, Quebec, Canada; Cambridge Isotope Laboratories Inc., Andover, MA, USA; and CombiPhos Catalysts, Inc., Princeton, NJ, USA. Further information regarding the state of the art with regard to deuterium-hydrogen exchange can be found, for example, in Hanzlik et al., J. Org. Chem., 1990, 55, 3992-3997; R.P. Hanzlik et al., Biochem. Biophys. Res. Commun., 1989, 160, 844; P. J. Reider et al., J. Org. Chem., 1987, 52, 3326-3334; M. Jarman et al., Carcinogenesis, 1993, 16(4), 683-688; J. Atzrodt et al., Angew. Chem., Int. Ed. 2007, 46, 7744; K. Matoishi et al., 2000, J. Chem. Soc, Chem. Commun., 1519-1520; K. Kassahun et al., WO 2012 / 112363.
[0032] The term "deuterium-containing compound of general formula (I)" is defined as a compound of general formula (I) in which one or more hydrogen atoms are replaced by one or more deuterium atoms and in which the abundance of deuterium in each deuterated position of the compound of general formula (I) is higher than the natural abundance of deuterium, which is about 0.015%. In particular, in a deuterium-containing compound of general formula (I), the abundance of deuterium in 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% in this position or these positions. It is understood that the abundance of deuterium in each deuterated position is independent of the abundance of deuterium in other deuterated positions.
[0033] By selectively incorporating one or more deuterium atoms into a compound of the general formula (I), the physicochemical properties (such as acidity [A. Streitwieser et al., J. Am. Chem. Soc., 1963, 85, 2759; C. L. Perrin et al., J. Am. Chem. Soc., 2007, 129, 4490], basicity [C. L. Perrin, et al., J. Am. Chem. Soc., 2003, 125, 15008; C. L. Perrin in Advances in Physical Organic Chemistry, 44, 144; 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 is changed and changes in the ratio of parent compound to metabolites or in the amounts of metabolites formed are caused. Such changes may result in certain therapeutic benefits and therefore may be preferred in certain circumstances. Decreased metabolic rates and metabolic switching, in which the ratio of metabolites changes, have been reported (D. J. Kushner et al., Can. J. Physiol. Pharmacol., 1999, 77, 79; A. E. Mutlib et al., Toxicol. Appl . Pharmacol., 2000, 169, 102). These changes in exposure to parent compound and metabolites may have important consequences with respect to the pharmacodynamics, tolerability and efficacy of a deuterium-containing compound of general formula (I). In some cases, deuterium replacement reduces or eliminates the formation of an undesirable or toxic metabolite and increases the formation of a desired metabolite (e.g. nevirapine: A. M. Sharma et al., Chem. Res.Toxicol., 2013, 26, 410; Uetrecht et al ., Chemical Research in Toxicology, 2008, 21, 9, 1862; Efavirenz: A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). In other cases, the main effect of deuteration is to reduce the rate of systemic clearance. This increases the biological half-life of the compound. Potential clinical benefits include the ability to maintain similar systemic exposure with reduced peak levels and increased trough levels. This could result in reduced side effects and increased efficacy depending on the pharmacokinetics / pharmacodynamics relationship of the compound in question. Examples of this deuterium effect are Indiplon (A. J. Morales et al., Abstract 285, The 15th North American Meeting of the International Society of Xenobiotics, San Diego, CA, October 12-16, 2008), ML-337 (C. J. Wenthur et al., J. Med. Chem., 2013, 56, 5208) and odanacatib (K. Kassahun et al., WO2012 / 112363). Other cases have also been reported in which reduced metabolic rates lead to an increase in drug exposure 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). Deuterated drugs that exhibit this effect may have reduced dosage requirements (e.g., lower number of doses or lower dosage to achieve the desired effect) and / or result in lower metabolite burdens.
[0034] A compound of general formula (I) may have several potential sites of attack for metabolism. To optimize the effects described above on the physicochemical properties and the metabolic profile, deuterium-containing compounds of the general formula (I) with a specific pattern of one or more deuterium-hydrogen exchanges can be selected. In particular, the cutcrium atom(s) of the cutcrium-containing compound (cn) of the general formula (I) is / are bound to a carbon atom and / or is / are in the positions of the compound of the general formula (I), which are attack sites for metabolic enzymes such as cytochrome P 450.

[0126] The compounds according to the invention show an unpredictable, valuable pharmacological and pharmacokinetic spectrum of activity.
[0127] They are therefore suitable for use as medicines for the treatment and / or prophylaxis of diseases in humans and animals.

[0128] The compounds according to the invention represent positive allosteric modulators of the muscarinic M2 receptor and are therefore suitable for the treatment and / or prevention of diseases and pathological processes, in particular cardiovascular diseases and / or kidney diseases, in which there is a dysregulation of the autonomic nervous system or an imbalance The M2 receptor is involved between the activity of the sympathetic and parasympathetic parts of the autonomic nervous system.
[0129] The subject of the present invention are positive allosteric modulators of the muscarinic M2 receptor. Allosteric modulators have clear differences compared to classic, orthosteric ligands. The effect of an allosteric modulator is self-limiting if it stabilizes the binding of the agonist at high concentrations. Furthermore, the effect of an allosteric modulator can only develop in the presence of the endogenous ligand. The allosteric modulator itself has no direct influence on receptor activation. This results in spatial and temporal specificity of the allosteric effect. The mutual influence of allosteric and orthosteric ligands in terms of affinity and intrinsic activity, known as cooperativity, is determined by the two ligands. In the case of a positive allosteric modulator, the effects of the orthosteric ligand are enhanced (positive cooperativity). Because of their ability to modulate receptor conformations in the presence of an orthosteric ligand, allosteric ligands can produce fine-tuning of pharmacological effects.

[0201] The compounds according to the invention can act systemically and / or locally. For this purpose, they can be applied in a suitable manner, such as oral, parenteral, pulmonary, nasal, sublingual, lingual, buccal, rectal, dermal, transdermal, conjunctival, otic or as an implant or stent.
[0202] For these routes of administration, the compounds according to the invention can be administered in suitable application forms.
[0203] Suitable for oral administration are application forms that function according to the prior art and release the compounds according to the invention quickly and / or in a modified manner and which contain the compounds according to the invention in crystalline and / or amorphized and / or dissolved form, such as tablets (uncoated or coated Tablets, for example with gastro-resistant or delayed-dissolving or insoluble coatings which control the release of the compound according to the invention), tablets or films / wafers that quickly disintegrate in the oral cavity, films / lyophilisates, capsules (for example hard or soft gelatin capsules), dragees, granules, Pellets, powders, emulsions, suspensions, aerosols or solutions.
[0204] Parenteral administration can occur bypassing an absorption step (e.g. intravenous, intraarterial, intracardiac, intraspinal or intralumbar) or by involving absorption (e.g. inhalative, intramuscular, subcutaneous, intracutaneous, percutaneous or intraperitoneal). Suitable forms of application for parenteral administration include injection and infusion preparations in the form of solutions, suspensions, emulsions, lyophilisates or sterile powders.
[0205] Suitable for the other routes of application are, for example, inhalation dosage forms (including powder inhalers, nebulizers, metered dose aerosols), nasal drops, solutions or sprays, tablets to be administered lingually, sublingually or buccally, films / wafers or capsules, suppositories, ear or eye preparations, vaginal capsules, aqueous Suspensions (lotions, shaking mixtures), lipophilic suspensions, ointments, creams, transdermal therapeutic systems (e.g. plasters), milk, pastes, foams, scattering powders, implants or stents.
[0206] Oral and parenteral administration are preferred, in particular oral, intravenous and intrapulmonary (inhalation) administration.
[0207] The compounds according to the invention can be converted into the application forms listed. This can be done in a manner known per se by mixing with inert, non-toxic, pharmaceutically suitable excipients. These excipients include, among others, carriers (e.g. microcrystalline cellulose, lactose, mannitol), solvents (e.g. liquid polyethylene glycols), emulsifiers and dispersants or wetting agents (e.g. sodium dodecyl sulfate, polyoxysorbitan oleate), binders (e.g. polyvinylpyrrolidone), synthetic and natural polymers (e.g. albumin) , stabilizers (e.g. antioxidants such as ascorbic acid), colorants (e.g. inorganic pigments such as iron oxides) and taste and / or odor correctors.
[0208] In general, it has proven to be advantageous to administer amounts of about 0.001 to 1 mg / kg, preferably about 0.01 to 0.5 mg / kg of body weight for parenteral administration in order to achieve effective results. When administered orally, 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 body weight.
[0209] Nevertheless, it may be necessary to deviate from the amounts mentioned, depending on body weight, route of application, individual behavior towards the active ingredient, type of preparation and time or interval at which the application takes place. In some cases it may be sufficient to get by with less than the aforementioned minimum quantity, while in other cases the aforementioned upper limit must be exceeded. If larger quantities are applied, it may be advisable to distribute them in several individual doses throughout the day.

[0218] The percentages in the following example and test descriptions are percentages by weight unless otherwise stated; Parts are parts by weight. Solvent ratios, dilution ratios and concentration information for liquid / liquid solutions each refer to the volume.
[0219] When purifying compounds according to the invention by preparative HPLC using the methods described, in which the eluents contain additives such as trifluoroacetic acid, formic acid or ammonia, the compounds according to the invention can be obtained in salt form, for example as trifluoroacetate, formate or ammonium salt, provided that the compounds according to the invention Compounds contain sufficient basic or acidic functionalities. Such a salt can be converted into the corresponding free base or acid using various methods known to those skilled in the art.
[0220] Purity information usually refers to corresponding peak integrations in the LC / MS chromatogram, but may also have been determined using the 1H NMR spectrum. If no purity is specified, it is usually 100% purity according to automatic peak integration in the LC / MS chromatogram or the purity was not explicitly determined.
[0221] Information on yields in % of theory. Th. are usually purity-corrected if a purity <100% is specified. For batches that contain solvents or are contaminated, the yield can formally be “>100%”; in these cases the yield is not corrected for solvent or purity.
[0222] The following descriptions of the coupling patterns of 1H-NMR signals were partly taken directly from the suggestions of the ACD SpecManager (ACD / Labs Release 12.00, Product version 12.5) and were not necessarily strictly questioned. In addition to these 1<H-NMR data, there may be additional widespread signals - due to the existing molecular dynamics (particularly in the range of 2.50 - 4.20 ppm) - which are not stated separately. Some of the SpecManager suggestions were adjusted manually. Manually adjusted or assigned descriptions are usually based on the visual appearance of the signals in question and do not necessarily correspond to a strict, physically correct interpretation. As a rule, the chemical shift information refers to the center of the signal in question. For wide multiplets, an interval is specified. Signals obscured by solvents or water were either tentatively assigned or are not listed. Strongly broadened signals - e.g. caused by rapid rotation of molecular parts or due to exchanging protons - have also been tentatively assigned (often referred to as broad multiplet or broad singlet) or are not listed.
[0223] The 1<H-NMR data of selected examples are recorded in the form of 1<H-NMR peak lists. For each signal peak, first the δ value is listed in ppm and then the signal intensity in round brackets. The δ -value signal intensity number pairs of different signal peaks are listed separated by commas. The peak list of an example therefore has the form: δ 1 (intensity 1 ), δ 2 (intensity 2 ), ... , δ i (intensity i ), ... , δ n (intensity n ).
[0224] The intensity of sharp signals correlates with the height of the signals in a printed example of an NMR spectrum in cm and shows the true ratios of the signal intensities when compared with other signals. For broad signals, multiple peaks or the center of the signal and their relative intensity compared to the most intense signal in the spectrum can be shown. The lists of H NMR peaks are similar to the classical 1< H NMR expressions and thus usually contain all the peaks listed in a classical NMR interpretation. In addition, like classic 1<H-NMR printouts, they can show solvent signals, signals from stereoisomers of the target compounds, which are also the subject of the invention, and / or peaks from impurities. The peaks of stereoisomers of the target compounds and / or peaks of impurities usually have, on average, a lower intensity than the peaks of the target compounds (for example with a purity of >90%). Such stereoisomers and / or impurities can be typical of the respective manufacturing process. Their peaks can thus help detect the reproduction of our manufacturing process using "by-product fingerprints". An expert who calculates the peaks of the target compounds using known methods (MestreC, ACD simulation, or using empirically evaluated expected values) can isolate the peaks of the target compounds as necessary, using additional intensity filters if necessary. This isolation would be similar to the relevant peak picking in the classical 1< H NMR interpretation. A detailed description of the representation of NMR data in the form of peak lists can be found in the publication "Citation of NMR Peaklist Data within Patent Applications" (cf. Research Disclosure Database Number 605005, 2014, August 1, 2014 or http: / / www. researchdisclosure.com / searching-disclosures). In the peak picking routine described in Research Disclosure Database Number 605005, the "MinimumHeight" parameter can be set between 1% and 4%. Depending on the type of chemical structure and / or depending on the concentration of the compound to be measured, it may make sense to set the "MinimumHeight" parameter to values <1%.

Alternatively, after acidification, extraction was carried out with ethyl acetate, the combined organic phases were dried over magnesium sulfate or sodium sulfate, filtered and the solvent was removed under reduced pressure. The crude product was then purified either using normal phase chromatography (silica gel, eluent: cyclohexane-ethyl acetate mixtures or dichloromethane-methanol mixtures) or preparative RP-HPLC (water-acetonitrile gradient). Alternatively, the reaction mixture was diluted with a little acetonitrile, water and formic acid and the crude solution obtained was purified using RP-HPLC (water-acetonitrile gradient). Further alternatives for processing, if carried out, are described in the respective experiment. AAV2

The corresponding amide (1.0-10 eq.) and the corresponding 7-chloro-4-oxo-1,4-dihydro-1,8-naphthyridine (1.0 eq.) were then added. The mixture was stirred at 80-110° C. for 1 hour (or until complete conversion according to analytical HPLC or thin layer chromatography with appropriate solvent mixtures). It was then cooled to RT and all volatile components were removed under reduced pressure or, alternatively, the reaction mixture was poured onto water, the pH was adjusted to pH 1 with 1M aqueous hydrochloric acid, extracted with ethyl acetate, and the combined organic phases with saturated aqueous sodium chloride solution washed, dried over magnesium sulfate, filtered and the solvent removed under reduced pressure. The crude product was then purified either using normal phase chromatography (eluent: cyclohexane-ethyl acetate mixtures or dichloromethane-methanol mixtures) or preparative RP-HPLC (water-acetonitrile gradient). Alternatively, the reaction mixture was diluted with a little acetonitrile, water and formic acid or TFA and the resulting crude solution was purified using RP-HPLC (water-acetonitrile gradient). Further alternatives for processing, if carried out differently, are described in the respective experiment. AAV3
[0229] A solution of the corresponding 7-chloro-4-oxo-1,4-dihydro-1,8-naphthyridine in DMF (0.10-0.22M) was mixed with the corresponding amine (1.2 eq.) and DIPEA (1.5-3.5 eq.). offset. The reaction solution was stirred at RT overnight. The crude product was then purified either after aqueous processing and extraction with the appropriate organic solvent using normal phase chromatography (eluent: cyclohexane-ethyl acetate mixtures or dichloromethane-methanol mixtures) or preparative RP-HPLC (water-acetonitrile gradient). Alternatively, the reaction mixture was diluted with a little acetonitrile, water and formic acid and the crude solution obtained was purified using RP-HPLC (water-acetonitrile gradient). Further alternatives for processing, if carried out, are described in the respective experiment.
