The present invention relates to a combination of a2 -Adrenoceptor subtype C (alpha-2C) antagonists, in particular substituted heterocyclic carboxamides of formula (I) and a norepinephrine (noradrenaline) reuptake inhibitor for the treatment and/or prophylaxis of sleep-related breathing disorders, preferably obstructive and central sleep apneas and snoring.

Background of the invention

Obstructive sleep apnoea (OSA) is a sleep-related respiratory disorder which is characterized by repetitive episodes of obstruction of the upper airways. When breathing in, the patency of the upper airways is ensured by the interaction of two opposite forces. The dilative effects of the musculature of the upper airways counteract the negative intraluminal pressure, which constricts the lumen. The active contraction of the diaphragm and the other auxiliary respiratory muscles generates a negative pressure in the airways, thus constituting the driving force for breathing. The stability of the upper respiratory tract is substantially determined by the coordination and contraction property of the dilating muscles of the upper airways.

Upper airway collapse in OSA is thought to occur at sleep onset because of the reduction of activity of several upper airway dilator muscles, which as a consequence are unable to maintain the anatomically vulnerable airway open. However, some upper airway dilator muscles, including the genioglossus muscle, which is the most important of the dilating muscles of the upper respiratory airway and which is innervated by the hypoglossal nerve, can increase activity during sleep in response to respiratory stimuli, potentially counteracting some of these changes at sleep onset. It was observed that OSA patients have apnea free intervals in which the genioglossus muscle activity is only 25-40% higher compared with sleep phases with frequent obstructive apneas (Jordan AS, White DP, Lo YL et al., Airway dilator muscle activity and lung volume during stable breathing in obstructive sleep apnea. Sleep 2009, 32(3): 361-8). Noradrenaline is one of the most potent neuromodulators of hypoglossal motoneuron activity (Homer R.L. Neuromodulation of hypoglossal motoneurons during sleep. Respir Physiol Neurobiol 2008, 164 (1-2): 179-196). It is thought, that decreased noradrenergic drive leads to sleep-dependent decline of hypoglossal motoneuron excitability resulting in reduced upper airway dilator muscle activity, especially reduced genioglossus muscle activity.

Alpha2C adrenoceptors regulate the release of noradrenaline from central noradrenergic neurons, they are autoreceptors involved in presynaptic feedback inhibition of noradrenaline (Hein L. et al, Two functionally distinct alpha2-adrenergic receptors regulate sympathetic neurotransmission Nature 1999, 402(6758): 181-184). An increase in the activity of the motoneurons of the hypoglossal nerve through Alpha2c adrenoceptor antagonism can stabilize the upper airways and protect them from collapse and occlusion. Moreover, also snoring can be inhibited through the mechanism of stabilization of the upper respiratory airways (Homer R.L. Neuromodulation of hypoglossal motoneurons during sleep. Respir Physiol Neurobiol 2008, 164 (1-2): 179-196).

For simple snoring, there is no obstruction of the upper airways. By the narrowing of the upper airways, the flow velocity of the inhaled and exhaled air increases. This together with the relaxed muscles causes fluttering of the soft tissues of the mouth and throat in the airflow. This slight vibration generated the typical snoring sounds.

Obstructive snoring (upper airway resistance syndrome, heavy snoring, hypopnea syndrome) is caused by a recurrent partial obstruction of the upper airway during sleep. This results in an increase in airway resistance and thus to an increase in work of breathing with significant intrathoracic pressure fluctuations. The negative intrathoracic pressure development during inspiration can thereby reach values as they occur as a result of a complete airway obstruction in OSA. The pathophysiological effects on the heart, circulation and sleep quality are the same as in obstructive sleep apnea. The pathogenesis is likely the same as in OSA. Obstructive snoring often provides the precursor for OSA (Hollandt J.H. et al., Upper airway resistance syndrome (UARS) -obstructive snoring. HNO 2000, 48(8): 628-634).

Central sleep apnea (CSA) occurs as a result of disturbed brain function or impaired respiratory regulation. CSA is characterized by a lack of drive to breathe during sleep, resulting in repetitive periods of insufficient or absent ventilation and compromised gas exchange. There are several manifestations of CSA. These include high altitude-induced periodic breathing, idiopathic CSA (ICSA), narcotic-induced central apnea, obesity hypoventilation syndrome (OHS), and Cheyne-Stokes breathing (CSB). While the precise precipitating mechanisms involved in the various types of CSA may vary considerably, unstable ventilatory drive during sleep is a principal underlying feature (Eckert D.J. et al., Central sleep apnea: Pathophysiology and treatment. Chest 2007, 131(2): 595-607).

US 2018/0235934 Al describes methods for treating disorders such as obstructive sleep apnea using agents for promoting hypoglossal motoneuron excitability. As agents for promoting hypoglossal motoneuron excitability a disinhibtor and/or stimulant of central noradrenic neurons is described. In some embodiments the disinhibitor of central noradrenergic neurons is an alpha2-adrenoceptor antagonist such as yohimbine or an alpha2 -adrenoceptor subtype A (alpha-2A) antagonists or alpha2- adrenoceptor subtype C (alpha-2C) antagonist. The alpha2 -adrenoceptor antagonist are selected from the group consisting of Atipamezole, MK-912, RS-79948, RX 821002, [3H]2-methoxy-idazoxan and JP- Alpha2C adrenoceptors belong to the family of G-protein coupled receptors. Beside the different Alpha 1 -adrenoceptors three different Alpha2 -adrenoceptor subtypes exist (Alpha2A, Alpha2B and Alpha2C). They are involved in the mediation of several diverse physiologic effects in different tissues upon stimulation by endogeneous catecholamines (epinephrine, norepinephrine), either derived from synapses or via the blood. Alpha2 adrenoceptors play an important physiological role, mainly in the cardiovascular system and in the central nervous system. Alpha2A- and Alpha2C-adrenoceptors are the main autoreceptors involved in presynaptic feedback inhibition of noradrenaline in the central nervous system. The potency and affinity of noradrenaline at the Alpha2C-adrenoceptor is higher than that for the Alpha2A-adrenoceptor. The Alpha2C-adrenoceptor inhibits noradrenaline release at low endogenous concentrations of noradrenaline, while Alpha2A -adrenoceptors inhibit noradrenaline release at high endogenous noradrenaline concentrations (Uys M.M. et al. Therapeutic Potential of Selectively Targeting the a2C-Adrenoceptor in Cognition, Depression, and Schizophrenia - New Developments and Future Perspective. Frontiers in Psychiatry 2017, Aug 14;8: 144. doi: 10.3389/fpsyt.2017.00144. eCollection 2017).

A further mechanism to increase endogenous noradrenaline levels is via inhibition of the norepinephrine transporter (NET). The norepinephrine transporter is located in the plasma membrane of noradrenergic neurons, where it regulates the take up of synaptically released norepinephrine (NE). Reuptake of NE by the NET protein is the primary mechanism by which the biological effects of NE in the synapse are terminated. A norepinephrine reuptake inhibitor increases the synaptic availability of NE (Zhou J Norepinephrine transporter inhibitors and their therapeutic potential. Drugs Future 2004 Dec;29(12):1235-1244).

.Noradrenaline reuptake inhibitors are described in the literature as agents for the treatment of depression and attention-deficit/hyperactivity disorder_(Aew/ J.M. SNaRIs, NaSSAs, and NaRIs: new agents for the treatment of depression. Lancet 2000 Mar ll;355(9207):911-8, Kratochvil C.J. et al., Atomoxetine: a selective noradrenaline reuptake inhibitor for the treatment of attention- deficit/hyperactivity disorder. Expert Opin Pharmacother 2003 Jul; 4 (7): 1165-74).

In WO 2018/200775 and WO 2019/152475 compositions for the treatment of conditions associated with pharyngeal airway muscle collapse while the subject is in a non-fullv conscious state, e.g.. sleep apnea and snoring, comprising administration of a norepinephrine reuptake inhibitor (NRI) and a muscarinic receptor antagonist are described.

Aryl piperazines as a2 -Adrenoceptor subtype C (alpha-2C) antagonists as well as their preparation and the use thereof as a medicament are known from WO 03/082866 Al where the compounds are disclosed as useful for the treatment for disorders such as disorder propagated by stress, Parkinson's disease, depression, schizophrenia, attention deficit hyperactivity disorder, post-traumatic stress disorder, obsessive compulsive disorder, Tourette's syndrome, blepharospasm or other focal dystonias, temporal lobe epilepsy with psychosis, a drug-induced psychosis, Huntington's disease, a disorder caused by fluctuation ofthe levels of sex hormones, panic disorder, Alzheimer's disease or mild cognitive impairment. There is nothing disclosed about the use of these compounds in the treatment of sleep- related breathing disorders, preferably obstructive and central sleep apneas and snoring.

WO 2021089683 describes substituted heterocyclic carboxamides as inhibitors of adrenoreceptor ADRA2C and their use for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of breathing difficulties including sleep-induced breathing difficulties such as central and obstructive sleep apnoea, snoring.

The current gold standard treatment for patients with OSA is continuous positive airway pressure (CPAP). The positive airflow pressure that is generated by an airflow turbine pump splints open the upper airway, reversing all potential causes of pharyngeal collapse, thereby preventing hypopneas, apneas and sleep fragmentation. Unfortunately, up to 50% of all patients with OSA do not tolerate CPAP in the long-term (M. Kohler, D. Smith, V. Tippett et al., Thorax 2010 65(9):829-32: Predictors of long-term compliance with continuous positive airway pressure). Therefore, there is still the need to find effective therapeutic agents for the treatment and/or prophalxis of sleep-related breathing disorders such as obstructive sleep apnea. Therefore the object of the present invention is to provide an effective therapeutic agent for the treatment and/or prophalxis of sleep-related breathing disorders, for example of obstructive sleep apnea, central sleep apnea and snoring.

Surprisingly, it has now been found that the combination of an a2-Adrenoceptor subtype C (alpha-2C) antagonist with a noradrenaline reuptake inhibitor inhibits upper airway collapsibility with synergistic efficacy and is thus suitable for the production of medicaments for the use in the treatment and/or prophylaxis of sleep-related breathing disorders, preferably obstructive and central sleep apneas and snoring. It was found that a synergism of the combination of an a2 -Adrenoceptor subtype C (alpha-2C) antagonists with a noradrenaline reuptake inhibitor allows lower doses of each treatment.

Compounds of the invention are the compounds of the formula (I) and the salts, solvates and solvates of the salts thereof, the compounds that are encompassed by formula (I) and are of the formulae mentioned below and the salts, solvates and solvates of the salts thereof and the compounds that are encompassed by formula (I) and are cited below as working examples and the salts, solvates and solvates of the salts thereof if the compounds that are encompassed by formula (I) and are mentioned below are not already salts, solvates and solvates of the salts.

Compounds of the invention are likewise /V-oxides and S-oxides of the compounds of the formula (I) and the salts, solvates and solvates of the salts thereof.

Preferred salts in the context of the present invention are physiologically acceptable salts of the compounds according to the invention. Also encompassed are salts which are not themselves suitable for pharmaceutical applications but can be used, for example, for the isolation, purification or storage of the compounds of the invention.

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 bearing a sufficiently basic nitrogen atom in a chain or in a ring, such as an acid-addition salt with an inorganic acid, or "mineral acid", such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, sulfamic acid, bisulfuric acid, phosphoric acid or nitric acid, for example, 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, pectinic acid, 3 -phenylpropionic acid, pivalic acid, 2-hydroxyethanesulfonic acid, itaconic acid, trifluoromethanesulfonic acid, dodecylsulfuric acid, ethanesulfonic acid, benzenesulfonic acid, para-toluenesulfonic acid, methanesulfonic acid, 2- naphthalenesulfonic acid, naphthalenedisulfonic 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, for example.

Further, another suitable pharmaceutically acceptable salt of a sufficiently acidic compound of the present invention is an alkali metal salt, for example a sodium or potassium salt, an alkaline earth metal salt, for example a calcium, magnesium or strontium salt, or an aluminum or zinc salt, or an ammonium salt derived from ammonia or from an organic primary, secondary or tertiary amine having 1 to 20 carbon atoms, such as ethylamine, diethylamine, triethylamine, ethyldiisopropylamine, monoethanolamine, diethanolamine, triethanolamine, dicyclohexylamine, dimethylaminoethanol, diethylaminoethanol, tris(hydroxymethyl)aminomethane, procaine, dibenzylamine, N- methylmorpholine, arginine, lysine, 1,2-ethylenediamine, /V-methylpiperidine, /V-methylglucamine, N.N- dimethylglucamine, /V-ethylglucamine, 1,6-hexanediamine, glucosamine, sarcosine, serinol, 2-amino- 1,3 -propanediol, 3-amino-l,2-propanediol, 4-amino- 1,2,3 -butanetriol, or a salt with a quarternary ammonium ion having 1 to 20 carbon atoms, such as tetramethylammonium, tetraethylammonium, tetra(«-propyl)ammonium, tetra(«-butyl)ammonium, A-bcnzyl-AA'A'-trimcthylammonium. choline or benzalkonium.

Those skilled in the art will further recognize that it is possible for acid addition salts of the claimed compounds to be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods. Alternatively, alkali and alkaline earth metal salts of acidic compounds of the present invention are prepared by reacting the compounds of the present invention with the appropriate base via a variety of known methods.

The present invention includes all possible salts of the compounds of the present invention as single salts, or as any mixture of said salts, in any ratio.

In the present text, in particular in the Experimental Section, for the synthesis of intermediates and of examples of the present invention, when a compound is mentioned as a salt form with the corresponding base or acid, the exact stoichiometric composition of said salt form, as obtained by the respective preparation and/or purification process, is, in most cases, unknown. Unless specified otherwise, suffixes to chemical names or structural formulae relating to salts, such as "hydrochloride", "trifluoroacetate", "sodium salt", or "x HQ", "x CF3COOH", "x Na ⁺ ", for example, mean a salt form, the stoichiometry of this salt not being specified. This applies analogously to cases in which synthesis intermediates or example compounds or salts thereof have been obtained as solvates, for example hydrates, by the preparation and/or purification processes described.

Solvates in the context of the invention are described as those forms of the compounds according to the invention which form a complex in the solid or liquid state by coordination with solvent molecules. Hydrates are a specific form of the solvates in which the coordination is with water. Solvates preferred in the context of the present invention are hydrates.

The compounds of the invention may, depending on their structure, exist in different stereoisomeric forms, i.e. in the form of configurational isomers or else, if appropriate, as conformational isomers (enantiomers and/or diastereomers, including those in the case of atropisomers). The present invention therefore encompasses the enantiomers and diastereomers, and the respective mixtures thereof. It is possible to isolate the stereoisomerically homogeneous constituents from such mixtures of enantiomers and/or diastereomers in a known manner. Preference is given to employing chromatographic methods for this purpose, especially HPLC chromatography on achiral or chiral separation phases. In the case of carboxylic acids as intermediates or end products, separation is alternatively also possible via diastereomeric salts using chiral amine bases.

In the context of the present invention, the term "enantiomerically pure" is understood to the effect that the compound in question with respect to the absolute configuration of the chiral centers is present in an enantiomeric excess of more than 95%, preferably more than 98%. The enantiomeric excess, ee, is calculated here by evaluating an HPLC analysis chromatogram on a chiral phase using the formula below:

If the compounds of the invention can occur in tautomeric forms, the present invention encompasses all the tautomeric forms.

The present invention also encompasses all suitable isotopic variants of the compounds of the invention. An isotopic variant of a compound according to the invention is understood here to mean a compound in which at least one atom within the compound according to the invention has been exchanged for another atom of the same atomic number, but with a different atomic mass from the atomic mass which usually or predominantly occurs in nature ("unnatural fraction"). The expression "unnatural fraction" is understood to mean a fraction of such an isotope higher than its natural frequency. The natural frequencies of isotopes to be employed in this connection can be found in "Isotopic Compositions of the Elements 1997", Pure Appl. Chem., 70(1), 217-235, 1998. Examples of isotopes which 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), 1 ³ C, ¹⁴ C, ¹⁵ N, ¹⁷ O, ¹⁸ O, ³² P, ³³ P, ³³ S, ³⁴ S, ³⁵ S, ³⁶ S, ¹⁸ F, ³⁶ C1, ⁸² Br, ¹²³ I, ¹²⁴ I, ¹²⁹ I and ¹³¹ I. Particular isotopic variants of a compound according to the invention, especially those in which one or more radioactive isotopes have been incorporated, may be beneficial, for example, for the examination of the mechanism of action or of the active ingredient distribution in the body; due to the comparatively easy preparability and detectability, especially compounds labeled with ³ H or ¹⁴ C isotopes are suitable for this purpose. In addition, the incorporation of isotopes, for example of deuterium, can lead to particular therapeutic benefits as a consequence of greater metabolic stability of the compound, for example an extension of the half-life in the body or a reduction in the active dose required; such modifications of the compounds of the invention may therefore possibly also constitute 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 the general formula (I) into which one or more radioactive isotopes such as ³ H or ¹⁴ C have been incorporated are beneficial, for example, in medicament and/or substrate tissue distribution studies. Because of their easy incorporability and detectability, these isotopes are particularly preferred. It is possible to incorporate positron-emitting isotopes such as ¹⁸ F or ⁿ C into a compound of the general formula (I). These isotopic variants of the compounds of the 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 within the scope of preclinical or clinical studies in mass spectrometry analyses (H. J. Leis et al., Curr. Org. Chem., 1998, 2, 131). Isotopic variants of the compounds of the invention can be prepared by commonly used processes known to those skilled in the art, for example by the methods described further down and the procedures described in the working examples, by using corresponding isotopic modifications of the respective reagents and/or starting compounds.

Isotopic variants of the compounds of the general formula (I) can generally be prepared by processes 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. According to the deuteration sites desired, it is possible in some cases to incorporate deuterium from D2O either directly into the compounds or into reagents which 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). A photochemical deuteration and tritiation method has also been described (Y. Y. Loh et al., Science 10.1126/science.aap9674 (2017). Another useful reagent for incorporation of deuterium into molecules is deuterium gas. A rapid route for 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). For direct exchange of hydrogen for deuterium in hydrocarbons containing functional groups, it is also possible to use metal catalysts (i.e. Pd, Pt and Rh) in the presence of deuterium gas (J. G. Atkinson et al., US Patent 3966781). Various deuterated reagents and synthesis units are commercially available from companies like, for example, C/D/N Isotopes, Quebec, Canada; Cambridge Isotope Laboratories Inc., Andover, MA, USA; and CombiPhos Catalysts, Inc., Princeton, NJ, USA. Further information relating to the prior 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. The term "deuterium-containing compound of the general formula (I)" is defined as a compound of the general formula (I) in which one or more hydrogen atoms have been replaced by one or more deuterium atoms and in which the frequency of deuterium in every deuterated position in the compound of the general formula (I) is higher than the natural frequency of deuterium, which is about 0.015%. More particularly, in a deuterium-containing compound of the general formula (I), the frequency of deuterium in every deuterated position in the compound of the general formula (I) is higher than 10%, 20%, 30%, 40%, 50%, 60%, 70% or 80%, preferably higher than 90%, 95%, 96% or 97%, even further preferably higher than 98% or 99%, in this position or these positions. It will be apparent that the frequency of deuterium in every deuterated position is independent of the frequency of deuterium in other deuterated positions.

The selective incorporation of one or more deuterium atoms into a compound of the general formula (I) can alter the physicochemical properties (for example 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, and cause changes in the ratio of parent compound to metabolites or the amounts of metabolites formed. Such changes may lead to particular therapeutic benefits and therefore be preferable under particular circumstances. Reduced rates of metabolism and metabolic switching, where the ratio of metabolites is changed, 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 the exposure to parent compound and metabolites can have important consequences with respect to the pharmacodynamics, tolerability and efficacy of a deuterium-containing compound of the 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; 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 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. Indiplon (A. J. Morales et al., Abstract 285, The 15 ^th 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) 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). 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.

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 profde, deuterium- containing compounds of general formula (I) having a certain pattern of one or more deuteriumhydrogen 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 P450.

The present invention additionally also encompasses prodrugs of the compounds of the invention. The term "prodrugs" refers here to compounds which may themselves be biologically active or inactive, but are converted while present in the body, for example by a metabolic or hydrolytic route, to compounds of the invention.

The preferred administration is the oral route.

For these administration routes, the compounds according to the invention can be administered in suitable administration forms.

For oral administration, administration forms which function according to the state of the art, releasing the compounds according to the invention rapidly and/or in a modified manner, which contain the compounds according to the invention in crystalline and/or amorphized and/or dissolved form, such as for example tablets (uncoated or coated tablets, for example with gastric juice-resistant or delayed dissolution or insoluble coatings, which control the release of the compound according to the invention), tablets rapidly disintegrating in the oral cavity or films/wafers, films/lyophilisates, capsules (for example hard or soft gelatine capsules), dragees, granules, pellets, powders, emulsions, suspensions, aerosols or solutions are suitable.

Parenteral administration can be effected omitting an absorption step (e.g. intravenous, intra-arterial, intracardial, intraspinal or intralumbar administration) or involving absorption (e.g. intra-muscular, subcutaneous, intracutaneous, percutaneous or intraperitoneal administration). Suitable administration forms for parenteral administration include injection and infusion preparations in the form of solutions, suspensions, emulsions, lyophilisates or sterile powders.

For the other administration routes, for example inhalation formulations (including powder inhalers and nebulisers), nasal drops, solutions or sprays, pharyngeal sprays, tablets for lingual, sublingual or buccal administration, tablets, films/wafers or capsules, suppositories, oral or ophthalmic preparations, vaginal capsules, aqueous suspensions (lotions, shakable mixtures), lipophilic suspensions, ointments, creams, transdermal therapeutic systems (e.g. plasters), milk, pastes, foams, dusting powders, implants or stents are suitable.

Oral administration is preferred.

The compounds according to the invention can be converted into the stated administration forms. This can be effected in a manner known per se by mixing with inert, non-toxic, pharmaceutically suitable additives. These additives include carriers (for example microcrystalline cellulose, lactose, mannitol), solvents (e.g. liquid polyethylene glycols), emulsifiers and dispersants or wetting agents (for example sodium dodecylsulphate, polyoxysorbitan oleate), binders (for example polyvinylpyrrolidone), synthetic and natural polymers (for example albumin), stabilizers (e.g. antioxidants such as for example ascorbic acid), colourants (e.g. inorganic pigments such as for example iron oxides) and flavour or odour correctors.

In general, to achieve effective results in oral administration it has been found advantageous to administer quantities of about 0.01 to 100 mg/kg, preferably about 0.1 to 10 mg/kg body weight. In nasal or pharyngeal administration, the dosage is about 0.01 pg/kg to 1000 pg/kg, preferably about 0.1 to 500 pg/kg body weight. Nonetheless it can sometimes be necessary to deviate from the said quantities, namely depending on body weight, administration route, individual response to the active substance, nature of the preparation and time or interval at which administration takes place. Thus in some cases it can be sufficient to manage with less than the aforesaid minimum quantity, while in other cases the stated upper limit must be exceeded. In the event of administration of larger quantities, it may be advisable to divide these into several individual administrations through the day.

The preferred administration is the oral route for a compound of of formula (I) and the oral route for the noradrenaline reuptake inhibitor.

For oral administration, administration forms which function according to the state of the art, releasing the compounds according to the invention rapidly and/or in a modified manner, which contain the compounds according to the invention in crystalline and/or amorphized and/or dissolved form, such as for example tablets (uncoated or coated tablets, for example with gastric juice-resistant or delayed dissolution or insoluble coatings, which control the release of the compound according to the invention), tablets rapidly disintegrating in the oral cavity or films/wafers, films/lyophilisates, capsules (for example hard or soft gelatine capsules), dragees, granules, pellets, powders, emulsions, suspensions, aerosols or solutions are suitable.

C. Experimental Methods - Combination of an al-Adrenoceptor subtype C (alpha-20 antagonists with a noradrenaline reuptake inhibitor

Advantageous pharmacological properties of the combination of an a2 -Adrenoceptor subtype C (alpha- 20 antagonists with a noradrenaline reuptake inhibitor can be determined by the following methods.

The therapeutic potential of the the combination of an a2-Adrenoceptor subtype C (alpha-2C) antagonists with a noradrenaline reuptake inhibitor according to the present invention in sleep apnea can be assessed preclinically in a pig model of obstructive sleep apnea (OSA).

Using negative pressure, it is possible to induce collapse and thus obstruction of the upper respiratory tract in anaesthetized, spontaneously breathing pigs (Wirth K.J. et al., Sleep 36(5) (2013) pp. 699-708). German Landrace pigs are used for the model. The pigs are anaesthetized and tracheotomized. Two tracheal cannulas are inserted into the trachea, one into the rostral part and the other into the caudal part of the trachea. Using a connection piece, the rostral cannula is connected to a tube to the negative pressure device and to the distal tracheal cannula. The distal tracheal cannula is additionally connected to a tube with an open end to atmosphere via a connection piece that served for free tracheal breathing, circumventing the upper airway. By appropriate opening and clamping of those tubes breathing can be switched from nasal breathing to breathing through the caudal tracheal cannula, circumventing the upper airway, and the (isolated) upper airway can be connected to the negative pressure device, causing airflow in the inspiratory direction.

At certain points in time, the collapsibility of the upper respiratory tract is tested by having the pig breathe via the caudal cannula and applying negative pressures of -50, -100 and -150 cm water head (cm H2O) to the upper respiratory tract. This causes the upper respiratory tract to collapse, which manifests itself in an interruption of the airflow and a pressure drop in the tube system. This test is conducted prior to the administration of the test substance and at certain intervals after the administration of the test substance. An appropriately effective test substance can prevent this collapse of the respiratory tract in the inspiratory phase.

In this OSA pig model, systemic application of the a2 -Adrenoceptor subtype C (alpha-2C) antagonists of formula (I), such as A-[(3,5-difluoropyridin-2-yl)methyl]-2-[(3J?)-3-methyl[l,4'- bipiperidin]-T-yl]- l,3-thiazole-5-carboxamide with intraduodenal administration of 0.01 mg/kg inhibited upper airway collapsibility at all negative pressures of -50, -100 and -150 cm head (cm H2O) in all pigs at no time point after intraduodenal application. At time point 120 min after intraduodenal administration, upper airway collapsibility was inhibited at the negative pressures of -50 and -100 cm head (cm H2O) and at time point 150 min after intraduodenal administration, upper airway collapsibility was inhibited at the negative pressure of -50 cm head (cm H2O) (see Table 1, 2 and 3 and Figure 1). Systemic application of the noradrenaline reuptake inhibitor atomoxetine via intravenous administration of a bolus injection of 20 pg/kg followed by an intravenous infusion of 12.5 pg/kg/h for four hours inhibited upper airway collapsibility at all negative pressures of -50, -100 and -150 cm head (cm H2O) in all pigs at no time (see Table 4, 5 and 6 and Figure 2. The combination of this non effective dose of the a2-Adrenoceptor subtype C (alpha-2C) antagonists of formula (I) A-|(3.5-difluoropyridin-2-yl)mcthyl |-2-|(3/?)-3- methyl[l,4'-bipiperidin]-T-yl]-l,3-thiazole-5-carboxamide with this non effective dose of the noradrenaline reuptake inhibitor atomoxetine inhibits upper airway collapsibility at all negative pressures of -50, -100 and -150 cm head (cm H2O) for more than five and a half hours (see Table 7, 8 and 9 and Figure 3).

It has been found that the combination of the non effective dose of the adrenoreceptor ADRA2C inhibitor with a non effective dose of the noradrenaline reuptake inhibitor atomoxetine, inhibits upper airway collapsibility with synergistic efficacy compared to each treatment alone. From the above mentioned data it can be deducted that the combination of an adrenoreceptor ADRA2C inhibitor of formula (I) with a noradrenaline reuptake inhibitor inhibits upper airway collapsibility with synergistic efficacy compared to each treatment alone and is thus suitable to treat sleep-related breathing disorders, preferably obstructive and central sleep apneas and snoring.
