Description:
AMINE SUBSTITUTED TRIAZOLE DERIVATIVES AND USES THEREOF

The present invention relates to novel amine substituted 1 ,2,4-triazole derivatives, to processes for the preparation of such compounds, to pharmaceutical compositions containing such compounds, and to the use of such compounds or compositions for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of renal and cardiovascular diseases.

The liquid content of the human body is subject to various physiological control mechanisms, the purpose of which is to keep it constant (volume homeostasis). In the process, both the volume filling of the vascular system and also the osmolarity of the plasma are continuously recorded by appropriate sensors (baroreceptors and osmoreceptors). The information which these sensors supply to the relevant centers in the brain regulates drinking behaviour and controls fluid excretion via the kidneys by means of humoral and neural signals. The peptide hormone vasopressin is of central importance in this [Schrier R.W., Abraham W.T., New Engl. J. Med. 341, 577-585 (1999)].

Vasopressin is produced in specialized endocrine neurons in the Nucleus supraopticus and N. para- ventricularis in the wall of the third ventricle (hypothalamus) and is transported from there along the neural processes into the posterior lobes of the hypophysis (neurohypophysis). There the hormone is released into the bloodstream in response to stimulus. A loss of volume, e.g. as a result of acute bleeding, heavy sweating, prolonged thirst or diarrhoea, is a stimulus for intensified release of the hormone. Conversely, the secretion of vasopressin is inhibited by an increase in the intravascular volume, e.g. as a result of increased fluid intake.

Vasopressin exerts its action mainly via binding to three receptors, which are classified as Via, Vlb and V2 receptors and which belong to the family of G protein-coupled receptors. Via receptors are mainly located on the cells of the vascular smooth musculature. Their activation gives rise to vasoconstriction, as a result of which the peripheral resistance and blood pressure rise. Apart from this, Via receptors are also detectable in the liver. Vlb receptors (also named V3 receptors) are detectable in the central nervous system. Together with corticotropin-releasing hormone (CRH), vasopressin regulates the basal and stress-induced secretion of adrenocorticotropic hormone (ACTH) via the Vlb receptor. V2 receptors are located in the distal tubular epithelium and the epithelium of the collecting tubules in the kidney. Their activation renders these epithelia permeable to water. This phenomenon is due to the incorporation of aquaporins (special water channels) in the luminal membrane of the epithelial cells.

The importance of vasopressin for the reabsorption of water from the urine in the kidney becomes clear from the clinical picture of diabetes insipidus, which is caused by a deficiency of the hormone, e.g. owing to hypophysis damage. Patients who suffer from this disease excrete up to 20 liters of urine per 24 hours if they are not given replacement hormone. This volume corresponds to about 10% of the primary urine. Because of its great importance for the reabsorption of water from the urine, vasopressin is also synonymously referred to as antidiuretic hormone (ADH). Consequently, pharmacological inhibition of the action of vasopressin/ADH on the V2 receptor results in increased urine excretion. In contrast to the action of other diuretics (thiazides and loop diuretics), however, V2 receptor antagonists cause increased water excretion, without substantially increasing the excretion of electrolytes. This means that with V2 antagonist drugs, volume homeostasis can be restored without affecting electrolyte homeostasis. Hence, drugs with V2 antagonistic activity appear particularly suitable for the treatment of all disease conditions which are associated with an overloading of the body with water, without the electrolytes being adequately increased in parallel.

A significant electrolyte abnormality is measurable in clinical chemistry as hyponatremia (sodium concentration < 135 mmol/L); it is the most important electrolyte abnormality in hospital patients, with an incidence of about 5% or 250 000 cases per year in the US alone. If the plasma sodium concentration falls below 1 15 mmol/L, comatose states and death are imminent. Depending on the underlying cause, a distinction is made between hypovolemic, euvolemic and hypervolemic hyponatremia. The forms of hypervolemia with edema formation are clinically significant. Typical examples of these are the syndrome of inappropriate ADH/vasopressin secretion (SIADH) (e.g. after craniocerebral trauma or as paraneoplasia in carcinomas) and hypervolemic hyponatremia in liver cirrhosis, various renal diseases and heart failure [De Luca L. et al., Am. J. Cardiol. 96 (suppl.), 19L-23L (2005)]. In particular, patients with heart failure, in spite of their relative hyponatremia and hypervolemia, often display elevated vasopressin levels, which are seen as the conse- quence of a generally disturbed neurohumoral regulation in heart failure [Francis G.S. et al., Circulation 82, 1724-1729 (1990)].

The disturbed neurohormonal regulation essentially manifests itself in an elevation of the sympathetic tone and inappropriate activation of the renin-angiotensin-aldosterone system. While the inhibition of these components by beta-receptor blockers on the one hand and by ACE inhibitors or angiotensin-receptor blockers on the other is now an inherent part of the pharmacological treatment of heart failure, the inappropriate elevation of vasopressin secretion in advanced heart failure is at present still not adequately treatable. Apart from the retention of water mediated by V2 receptors and the unfavourable hemodynamic consequences associated therewith in terms of increased backload, the emptying of the left ventricle, the pressure in the pulmonary blood vessels and cardiac output are also adversely affected by V la-mediated vasoconstriction. Furthermore, on the basis of experimental data in animals, a direct hypertrophy -promoting action on the heart muscle is also attributed to vasopressin. In contrast to the renal effect of volume expansion, which is mediated by activation of V2 receptors, the direct action on the heart muscle is triggered by activation of Via receptors.

For these reasons, agents which inhibit the action of vasopressin on the V2 and/or the Via receptor appear suitable for the treatment of heart failure. In particular, compounds with combined activity on both vasopressin receptors (Via and V2) should have both desirable renal as well as hemodynamic effects and thus offer an especially ideal profile for the treatment of patients with heart failure. The provision of such combined vasopressin antagonists also appears to make sense inasmuch as a volume diminution mediated solely via V2 receptor blockade can entail the stimulation of osmoreceptors and, as a result, may lead to a further compensatory increase in vasopressin release. Through this, in the absence of a component simultaneously blocking the Via receptor, the harmful effects of vasopressin, such as for example vasoconstriction and heart muscle hypertrophy, could be further intensified [Saghi P. et al., Europ. Heart J. 26, 538-543 (2005)].

Via receptors are mainly located on vascular smooth muscle cells (VSMC) but also on cardiomyocytes, fibroblasts and specialized renal cells like glomerular mesangial cells or cells of the macula densa which control the release of renin [Wasilewski MA, Myers VD, Recchia FA, Feldman AM, Tilley DG, Cell Signal., 28(3), 224-233, (2016)]. The activation of VSMC Via receptor by vasopressin gives rise to intracellular calcium release and according vasoconstriction. Therefore, stimulation of VSMC Via receptors causes increased vascular resistance and increased cardiac afterload. Cardiac output is adversely affected by V la-mediated vasoconstriction. The increase in afterload and direct stimulation of Via receptors on cardiomyocytes can lead to cardiac hypertrophy and remodeling including fibrosis. Mice with cardiac-specific overexpression of Via receptor develop cardiac hypertrophy leading to dilation and left ventricular dysfunction, suggesting an essential role for Via receptor in the development of heart failure [Li X, Chan TO, Myers V, Chowdhury I, Zhang XQ, Song J, Zhang J, Andrei J, Funakoshi H, Robbins J, Koch WJ, Hyslop T, Cheung JY, Feldman AM, Circulation.; 124, 572-581 (201 1)].

Via receptor is also expressed in the renal cortical and medullary vasculature, where it mediates vasoconstriction of renal vessels and affecting overall renal blood flow. Thus, the activation of Via receptor can decrease renal medullary blood flow inducing further pathological processes as tissue hypoxia, reduced oxygen and accordingly energy supply for tubular transport processes as well as direct damages of mesangial and macula densa cells. It has been demonstrated that mesangial Via receptor activation mediates TGF signaling and causes an increase in production of collagen IV. While this signaling contributes extracellular matrix accumulation and remodeling in the kidney, similar signaling pathways are believed to occur in cardiac cells especially after myocardial infarction, which emphasizes the central role of Via receptor in the development of hypertrophic and fibrotic processes in response to pathophysiological elevated vasopressin levels [Wasilewski MA, Myers VD, Recchia FA, Feldman AM, Tilley DG. Arginine vasopressin receptor signaling and functional outcomes in heart failure. Cell Signal., 28(3), 224-233 (2016)].

Since Via receptors are mainly expressed on VSMCs and thus participating in vascular function, a link to vascular diseases as peripheral arterial disease (PAD) including claudication and critical limb ischemia as well as coronary microvascular dysfunction (CMD) is conceivable. Apart from this, Via receptors are also expressed on human platelets and in the liver. The meaning of platelet Via receptors is not fully understood although vasopressin induces aggregation of human platelets via Via receptor at high concentrations ex vivo. Therefore, inhibition of vasopressin- induced platelet aggregation by Via receptor antagonists is a useful pharmacological ex vivo assay making use of human tissue endogenously expressing the Via receptor [Thibonnier M, Roberts JM, J Clin Invest; 76: 1857-1864, (1985)].

Vasopressin stimulates gluconeogenesis and glycogenolysis via activation of the hepatic Via receptor. Animal studies have shown that vasopressin impairs glucose tolerance which could be inhibited by a Via receptor antagonist thereby providing a link of vasopressin receptor Via to diabetes mellitus. [Taveau C, Chollet C, Waeckel L, Desposito D, Bichet DG, Arthus MF, Magnan C, Philippe E, Paradis V, Foufelle F, Hainault I, Enhorning S, Velho G, Roussel R, Bankir L, Melander O, Bouby N. Vasopressin and hydration play a major role in the development of glucose intolerance and hepatic steatosis in obese rats. Diabetologia., 58(5), 1081 -1090, (2015)]. Vasopressin was shown to contribute to the development of albuminuria and to diabetes-induced nephropathy in animal models which is consistent with epidemiological findings in humans.

It was found recently that vasopressin also seems to play a causal role in the development of preeclampsia. Chronic infusion of vasopressin during pregnancy in mice is sufficient to induce all of the major maternal and fetal phenotypes associated with human preeclampsia, including pregnancy-specific hypertension [Santillan MK, Santillan DA, Scroggins SM, Min JY, Sandgren JA, Pearson NA, Leslie KK, Hunter SK, Zamba GK, Gibson-Corley KN, Grobe JL. Vasopressin in preeclampsia: a novel very early human pregnancy biomarker and clinically relevant mouse model. Hypertension. 64(4), 852-859, (2014)].

Vasopressin levels can be elevated in women with dysmenorrhoea (a gynecological disorder which is characterised by cyclical cramping pelvic pain) during menstruation, which appear to increase myometrial smooth muscle contraction. It was found recently that a selective vasopressin Via receptor antagonist (relcovaptan/SR-49059) can reduce intrauterine contractions elicited by vasopressin.

For these reasons, agents which inhibit the action of vasopressin on the Via receptor appear suitable for the treatment of several cardiovascular diseases. In particular, agents which inhibit the action of vasopressin selectively on the Via receptor offer an especially ideal profile for the treatment of otherwise normovolemic patients, i.e. those which are not eligible for decongestion by e.g. high doses of loop diuretics or V2 antagonists, and where induced aquaresis via V2 inhibition may be undesired.

Certain 4-phenyl-l,2,4-triazol-3-yl derivatives have been described in WO 2005/063754-A1 and WO 2005/105779-A1 to act as vasopressin Via receptor antagonists that are useful for the treatment of gynecological disorders, notably menstrual disorders such as dysmenorrhea. In WO 201 1/104322-A1, a particular group of bis-aryl-bonded l,2,4-triazol-3-ones, including 5-phenyl-l,2,4-triazol-3-yl and 1 -phenyl- l,2,3-triazol-4-yl derivatives thereof, has been disclosed as antagonists of vasopressin Via and/or V2 receptors being useful for the treatment and/or prevention of cardiovascular diseases.

In WO 2016/071212-A1 certain 5-(hydroxyalkyl)-l -phenyl- 1 ,2,4-triazole derivatives have been disclosed, which act as potent antagonists of both vasopressin Via and V2 receptors and, in addition, exhibit significantly enhanced aquaretic potency in vivo after oral application.

In WO 2017/191 107-A1 and WO 2017/191 102-A1 certain 5-(carboxamide)-l -phenyl- 1,2,4- triazole derivatives as well as in WO 2017/191 1 14-A1 specific 5-(hydroxyalkyl)-l-heteroaryl- 1,2,4-triazole derivatives have been described, which represent highly potent and selective antagonists of the Via receptor and are particularly useful for the treatment and/or prevention of renal and cardiovascular diseases in subjects which do not suffer from fluid overload and who therefore should not be decongested.

Further novel 5-(carboxamide)-substituted, 5-(fluoroalkyl)-substituted and 3-(hydroxyalkyl)- substituted 1,2,4-triazole derivatives have been disclosed as antagonists of vasopressin V2 and/or Via receptors in WO 2017/191 105-Al, WO 2017/191 1 12-Al, WO 2017/191 1 15-Al and WO 2018/073144-A1.

It was an object of the present invention to provide novel compounds which act as potent selective or dual Vla/V2 receptor antagonists and as such are suitable for the treatment and/or prevention of diseases, more particularly for the treatment and/or prevention of renal and cardiovascular disorders.

The compounds of the present invention have valuable pharmacological properties and can be used for the prevention and/or treatment of various diseases and disease-induced states in humans and other mammals.

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).

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.

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.

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.

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), U C, 13 C, 14 C, 15 N, 17 0, 18 0, 32 P, 33 P, 33 S, 34 S, 35 S, 36 S, 18 F, 36 C1, 82 Br, 123 I, 124 I, 125 I, 129 I and 131 I, respectively.

With respect to the treatment and/or prevention 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 U 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 (H. J. Leis et al., Curr. Org. Chem., 1998, 2, 131) in the context of preclinical or clinical studies.

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 (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. 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 Letters, 201 1, 52, 3865) is a direct 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 (J. G. Atkinson et al., US Patent 3966781). 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. Further information on the state of the art with respect to deuterium-hydrogen exchange is given for example in Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990; R. P. Hanzlik et al., Biochem. Biophys. Res. Commun. 160, 844, 1989; P. J. Reider et al., J. Org. Chem. 52, 3326-3334, 1987; M. Jarman et al., Carcinogenesis 16(4), 683-688, 1995; J. Atzrodt et al., Angew. Chem., Int. Ed. 2007, 46, 7744; K. Matoishi et al., Chem. Commun. 2000, 1519-1520; K. Kassahun et al., WO2012/1 12363.

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).

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; A. Streitwieser et al., J. Am. Chem. Soc, 1963, 85, 2759;], basicity [C. L. Perrin et al., J. Am. Chem. Soc, 2005, 127, 9641 ; C. L. Perrin, et al., J. Am. Chem. Soc, 2003, 125, 15008; C. L. Perrin in Advances in Physical Organic Chemistry, 44, 144], 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; D. J. Kushner et al., Can. J. Physiol. Pharmacol., 1999, 77, 79). 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). 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., WO2012/1 12363) 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 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 P450.

Where the plural form of the word compounds, salts, polymorphs, hydrates, solvates and the like, is used herein, this is taken to mean also a single compound, salt, polymorph, isomer, hydrate, solvate or the like.

By "stable compound' or "stable structure" is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.

The compounds of the present invention optionally contain one asymmetric centre, depending upon the location and nature of the various substituents desired. It is possible that one asymmetric carbon atom is present in the (R) or (S) configuration, which can result in racemic mixtures. In certain instances, it is possible that asymmetry also be present due to restricted rotation about a given bond, for example, the central bond adjoining two substituted aromatic rings of the specified compounds. Preferred compounds are those which produce the more desirable biological activity. Separated, pure or partially purified isomers and stereoisomers or racemic mixtures of the compounds of the present invention are also included within the scope of the present invention. The purification and the separation of such materials can be accomplished by standard techniques known in the art.

The 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., HPLC columns using a chiral phase), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable HPLC columns using a chiral phase are commercially available, such as those manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ, for example, among many others, which are all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of the present invention can likewise be obtained by chiral syntheses utilizing optically active starting materials. In order to distinguish different types of isomers from each other reference is made to IUPAC Rules Section E (Pure Appl Chem 45, 1 1 -30, 1976).

The present invention includes all possible stereoisomers of the compounds of the present invention as single stereoisomers, or as any mixture of said stereoisomers, e.g. (R)- or (S)- isomers, in any ratio. Isolation of a single stereoisomer, e.g. a single enantiomer or a single diastereomer, of a compound of the present invention is achieved by any suitable state of the art method, such as chromatography, especially chiral chromatography, for example.

In the context of the present invention, the term "enantiomerically pure" is to be understood as meaning that the compound in question with respect to the absolute configuration of the chiral centre is present in an enantiomeric excess of more than 95%, preferably more than 97%. The enantiomeric excess, ee, is calculated here by evaluating of the corresponding HPLC chromatogram on a chiral phase using the formula below:

ee = [E A (area%) - E B (area%)] x 100% / [E A (area%) + E B (area%)] (E A : major enantiomer, E B : minor enantiomer)

Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of cardiovascular and renal disorders, by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known active ingredients or medicaments that are used to treat these conditions, the effective dosage of the compounds of the present invention can readily be determined for treatment of each desired indication. The amount of the active ingredient to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular compound and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated.

The total amount of the active ingredient to be administered will generally range from about 0.001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 20 mg/kg body weight per day. Clinically useful dosing schedules will range from one to three times a day dosing to once every four weeks dosing. In addition, it is possible for "drug holidays", in which a patient is not dosed with a drug for a certain period of time, to be beneficial to the overall balance between pharmacological effect and tolerability. It is possible for a unit dosage to contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. Illustratively, the compound of the present invention may be administered parenterally at a dose of about 0.001 mg/kg to about 10 mg/kg, preferably of about 0.01 mg/kg to about 1 mg/kg of body weight. In oral administration, an exemplary dose range is about 0.01 to 100 mg/kg, preferably about 0.01 to 20 mg/kg, and more preferably about 0.1 to 10 mg/kg of body weight. Ranges intermediate to the above -recited values are also intended to be part of the invention.

Of course the specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compound employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of treatment and number of doses of a compound of the present invention or a pharmaceutically acceptable salt or ester or composition thereof can be ascertained by those skilled in the art using conventional treatment tests.

The following exemplary embodiments illustrate the invention. The invention is not restricted to the examples.

The various aspects of the invention described in this application are illustrated by the following examples which are not meant to limit the invention in any way.

The example testing experiments described herein serve to illustrate the present invention and the invention is not limited to the examples given.

All reagents, for which the synthesis is not described in the experimental part, are either commercially available, or are known compounds or may be formed from known compounds by known methods by a person skilled in the art.

The compounds and intermediates produced according to the methods of the invention may require purification. Purification of organic compounds is well known to the person skilled in the art and there may be several ways of purifying the same compound. In some cases, no purification may be necessary. In some cases, the compounds may be purified by crystallization. In some cases, impurities may be stirred out using a suitable solvent. In some cases, the compounds may be purified by chromatography, particularly flash column chromatography, using for example prepacked silica gel cartridges, e.g. Biotage SNAP cartidges KP-Sil ® or KP-NH ® in combination with a Biotage autopurifier system (SP4 ® or Isolera Four ® ) and eluents such as gradients of hexane/ethyl acetate or DCM/methanol. In some cases, the compounds may be purified by preparative HPLC using for example a Waters autopurifier equipped with a diode array detector and/or on-line electrospray ionization mass spectrometer in combination with a suitable prepacked reverse phase column and eluents such as gradients of water and acetonitrile which may contain additives such as trifluoroacetic acid, formic acid or aqueous ammonia.

In some cases, purification methods as described above can provide those compounds of the present invention which possess a sufficiently basic or acidic functionality in the form of a salt, such as, in the case of a compound of the present invention which is sufficiently basic, a trifluoroacetate or formate salt for example, or, in the case of a compound of the present invention which is sufficiently acidic, an ammonium salt for example. A salt of this type can either be transformed into its free base or free acid form, respectively, by various methods known to the person skilled in the art, or be used as salts in subsequent biological assays. It is to be understood that the specific form (e.g. salt, free base etc.) of a compound of the present invention as isolated and as described herein is not necessarily the only form in which said compound can be applied to a biological assay in order to quantify the specific biological activity.

In the case of the synthesis intermediates and working examples of the invention described hereinafter, any compound specified in the form of a salt of the corresponding base or acid is generally a salt of unknown exact stoichiometric composition, as obtained by the respective preparation and/or purification process. Unless specified in more detail, additions to names and structural formulae, such as "hydrochloride", "trifluoroacetate", "sodium salt" or "x HQ", "x CF3COOH", "x Na + " should not therefore be understood in a stoichiometric sense in the case of such salts, but have merely descriptive character with regard to the salt-forming components present therein.

This applies correspondingly if synthesis intermediates or working examples or salts thereof were obtained in the form of solvates, for example hydrates, of unknown stoichiometric composition (if they are of a defined type) by the preparation and/or purification processes described.

B-l. Cellular in vitro assay for determining vasopressin receptor activity

The identification of agonists and antagonists of the Via and V2 vasopressin receptors from humans, rats and dogs as well as the quantification of the activity of the compounds of the invention is carried out using recombinant cell lines. These cell lines originally derive from a hamster's ovary epithelial cell (Chinese Hamster Ovary, CHO Kl, ATCC: American Type Culture Collection, Manassas, VA 20108, USA). The test cell lines constitutively express the human, rat or dog Via or V2 receptors. In case of the G a -coupled Via receptors, cells are also stably transfected with a modified form of the calcium-sensitive photoproteins aequorin (human and rat Via) or obe- lin (dog Via), which, after reconstitution with the cofactor coelenterazine, emit light when there are increases in free calcium concentrations [Rizzuto R, Simpson AW, Brini M, Pozzan T, Nature 358. 325-327 (1992); Illarionov BA, Bondar VS, Illarionova VA, Vysotski ES, Gene 153 (2), 273- 274 (1995)]. The resulting vasopressin receptor cells react to stimulation of the recombinantly expressed Via receptors by intracellular release of calcium ions, which can be quantified by the resulting photoprotein luminescence. The G s -coupled V2 receptors are stably transfected into cell lines expressing the gene for firefly luciferase under control of a CRE-responsible promoter. Activation of V2 receptors induces the activation of the CRE-responsive promoter via cAMP increase, thereby inducing the expression of firefly luciferase. The light emitted by photoproteins of Via cell lines as well as the light emitted by firefly luciferase of V2 cell lines corresponds to the activation or inhibition of the respective vasopressin receptor. The bioluminescence of the cell lines is detected using a suitable luminometer [Milligan G, Marshall F, Rees S, Trends in Pharmacological Sciences 17, 235-237 (1996)].

Test procedure:

Vasopressin Via receptor cell lines:

On the day before the assay, the cells are plated out in culture medium (DMEM/F12, 2% FCS, 2 mM glutamine, 10 mM HEPES, 5 μg/ml coelenterazine) in 384-well microtiter plates and kept in a cell incubator (96% humidity, 5% v/v CO 2 , 37°C). On the day of the assay, test compounds in various concentrations are placed for 10 minutes in the wells of the microtiter plate before the agonist [Arg 8 ] -vasopressin at EC 5 0 concentration is added. The resulting light signal is measured immediately in a luminometer.

Vasopressin V2 receptor cell lines:

On the day before the assay, the cells are plated out in culture medium (DMEM/F12, 2% FCS, 2 mM glutamine, 10 mM HEPES) in 384-well microtiter plates and kept in a cell incubator (96% humidity, 5% v/v CO2, 37°C). On the day of the assay, test compounds in various concentrations and the agonist [Arg 8 ] -vasopressin at EC50 concentration are added together to the wells, and plates are incubated for 3 hours in a cell incubator. Upon addition of the cell lysis reagent Triton and the substrate luciferin, luminescence of firefly luciferase is measured in a luminometer.

B-2. Radioactive binding assay

IC50 and Ki values can be determined in radioactive binding assays using membrane fractions of recombinant human embryonic kidney cell line 293 (HEK293) or CHO-Kl cell lines expressing the respective human vasopressin Via and V2 receptors.

Human recombinant vasopressin Via receptors expressed in HEK293 cells are used in 50 mM Tris-HCl buffer, pH 7.4, 5 mM MgCi2, 0.1% BSA using standard techniques. Aliquots of prepared membranes are incubated with test compounds in various concentrations in duplicates and 0.03nM [ 125 I]Phenylacetyl-D-Tyr(Me)-Phe-Gln-Asn-Arg-Pro-Arg-Tyr-N H 2 for 120 minutes at 25°C. Nonspecific binding is estimated in the presence of 1 μΜ [Arg 8 ]Vasopressin. Receptors are filtered and washed, the filters are then counted to determine [ 125 I]Phenylacetyl-D-Tyr(Me)-Phe-Gln-Asn-Arg- Pro-Arg-Tyr-NH2 specifically bound.

CHO-Kl cells stably transfected with a plasmid encoding human vasopressin V2 receptor are used to prepare membranes in 50 mM Tris-HCl buffer, pH 7.4, 10 mM MgCh, 0.1% BSA using standard techniques. Aliquots of prepared membrane are incubated with test compounds in various concentrations in duplicates and 4 nM [ 3 H](Arg 8 )-Vasopressin for 120 minutes at 25°C. Nonspecific binding is estimated in the presence of 1 mM (Arg 8 )-vasopressin. Membranes are filtered and washed 3 times and the filters are counted to determine [ 3 H](Args)- Vasopressin specifically bound.

IC50 values are determined by a non-linear, least squares regression analysis using MathlQTM (ID Business Solutions Ltd., UK). The inhibition constant K; is calculated using the equation of Cheng and Prusoff (Cheng, Y., Prusoff, W.H., Biochem. Pharmacol. 22:3099-3108, 1973).

B-3. Cellular in vitro assay for detecting the action of vasopressin Via receptor antagonists on the regulation of pro-fibrotic genes

The cell line H9C2 (American Type Culture Collection ATCC No. CRL-1446), described as a cardiomyocyte type isolated from rat cardiac tissue, endogenously expresses the vasopressin Via receptor AVPR1A in high copy number, whereas AVPR2 expression cannot be detected. Likewise, the cell line NRK49F (ATCC No. CRL1570) isolated from rat kidney tissue, shows similar expression pattern of high AVPR1A mRNA expression and diminishing AVPR2 expression. For cell assays detecting the inhibition of AVPR1A receptor-dependent regulation of gene expression by receptor antagonists, the procedure is as follows:

H9C2 cells or NRK49F cells are seeded in 6-well microtiter plates for cell culture at a cell density of 50 000 cells/ well in 2.0 ml of Opti-MEM medium (Invitrogen Corp., Carlsbad, CA, USA, Cat. No. 11058-021) and held in a cell incubator (96% humidity, 8% v/v C0 2 , 37°C). After 24 hours, sets of three wells (triplicate) are charged with vehicle solution (negative control) and vasopressin solution ([Arg8]-vasopressin acetate, Sigma, Cat. No. V9879), or test compound (dissolved in vehicle: water with 20% v/v ethanol) and vasopressin solution. In the cell culture, the final vasopressin concentration is 1 nM. The test compound solution is added to the cell culture in small volumes, so that a final concentration of 0.03% of ethanol in the cell assay is not exceeded. After an incubation time of 5 hours, the culture supernatant is drawn off under suction, the adherent cells are lysed in 350 μΐ of RLT buffer (Qiagen, Cat. No. 79216), and the RNA is isolated from the lysate using the RNeasy kit (Qiagen, Cat. No. 74104). This is followed by DNAse digestion (Invitrogen, Cat. No. 18068-015), cDNA synthesis (Promaga, ImProm-II Reverse Transcription System, Cat. No. A3800) and Reverse Transcription Polymerase Chain Reaction (RTPCR) (pPCR MasterMix RT-QP2X-03-075, Eurogentec, Seraing, Belgium). All procedures take place in accordance with the working protocols of the test reagents' manufacturers. The primer sets for the RTPCR are selected on the basis of the mRNA gene sequences (NCBI GenBank Entrez Nucleotide Data Base) using the Primer3Plus program with 6-FAM TAMRA-labelled probes. The RTPCR for determining the relative mRNA expression in the cells of the various assay batches is carried out using the Applied Biosystems ABI Prism 7700 Sequence Detector in 384 -well microtiter plate format in accordance with the instrument operating instructions. The relative gene expression is represented by the delta-delta Ct value [Applied Biosystems, User Bulletin No. 2 ABI Prism 7700 SDS, December 1 1, 1997 (updated 10/2001)] with reference to the level of expression of the ribosomal protein L-32 gene (GenBank Acc. No. NM_013226) and the threshold Ct value of Ct = 35.

B-4. Inhibition of vasopressin induced aggregation of human platelets

Human platelets endogenously express the Via receptor. It was found that relatively high vasopressin concentrations (ca. 50-100 nM) stimulate platelet aggregation ex vivo. Therefore, platelets enriched from human blood may serve as a Via expressing tissue for pharmacological studies with corresponding high concentrations of vasopressin antagonists.

Human blood is collected in a 10 mM trisodium citrate solution by venous puncture from nonsmoking healthy volunteers (n=4-8) who were drug free for at least 1 week. Platelet-rich plasma (PRP) is obtained by centrifuging the blood sample at 140 g for 20 min at 4°C. The resulting pellet is further centrifuged (15.000 rpm, 2 min) to produce platelet-poor plasma (PPP). Platelet aggregation is measured turbidimetrically using an aggregometer (APACT 4). The reaction is followed by monitoring changes in light transmission on 178 μΐ ^ PRP aliquots, under continuous stirring at 37°C, against PPP control. Various concentrations of vasopressin antagonists (in 2 μΐ.) are added to PRP 5 min before the addition of 20 μΐ ^ Arg -vasopressin (final concentration 100 nM. The inhibitory effects of the compounds are determined by measuring the height of the aggregation wave from the bottom of the shape change compared with the control response. IC50 values are calculated a dose-response inhibition curve by an iterative nonlinear regression program

B-5. Effects on the contraction of isolated rat vessel rings

Isolated aorta

Test compounds can be investigated on isolated aortic rings from male Wistar rats endogenously expressing the Via receptor. Male Wistar rats are euthanized using carbon dioxide. The aorta is removed and placed in ice-cold Krebs-Henseleit buffer of following composition (in mmol/1): NaCl 112, KC1 5.9, CaCl 2 2.0, MgCl 2 1.2, NaH 2 P0 4 1.2, NaHCOs 25, glucose 1 1.5. The aorta is cut into 3 mm rings and transferred to 20 ml organ baths containing Krebs-Henseleit solution equilibrated with 95% 0 2 , 5% CO2 at 37°C. For recording of isometric tension the rings are mounted between two hooks. The resting tension is adjusted to 3 g. After an equilibration period, each experiment is started by exposing the preparation to K+ (50 mM) Krebs-Henseleit solution. The aortic rings are than pre-contracted using 1 nmol/1 Arg-vasopressin. After a stable contraction is established, a cumulative dose response curve of the test compound is constructed. The stabilized contraction induced by Arg-vasopressin is defined as 100% tension. The relaxation is expressed as percentage tension.

Isolated A. renalis

Male Wistar rats (200-250 g) are euthanized using carbon dioxide. The A. renalis is removed and placed in ice-cold Krebs-Henseleit buffer of following composition (in mmol/1): NaCl 1 12, KC1 5.9, CaCl 2 2.0, MgCl 2 1.2, NaH 2 P0 4 1.2, NaHCOs 25, glucose 1 1.5. For measurement of isometric tension, ring segments, 2 mm in length, are mounted in a small vessel chamber myograph (Danish Myo Technology A/S, Denmark) using two tungsten wires fixed to mounting jaws. One mounting jaw is attached to a micrometer, allowing control of vessel circumference. The other mounting jaw is attached to a force transducer for measurement of tension development. The whole preparation is kept in a chamber with physiological salt solution at 37°C, bubbled with oxygen. After a 30 min equilibration period, the vessels are stretched to their optimal lumen diameter for active tension development which is determined based on the internal circumference-wall tension ratio. The internal circumference is set to 90% of what the vessels would have if they are exposed to a passive tension equivalent to that produced by a transmural pressure of 100 mmHg.

Afterwards, the vessels are washed three times with Krebs-Henseleit buffer and left to equilibrate for 30 min. The contractility is then tested by a twofold exposure to a high K + solution (50 mmol/1 KC1). After washing with Krebs-Henseleit buffer the vessels are then pre-contracted using 1 nmol/1 Arg-vasopressin. After a stable contraction is established, a cumulative dose response curve of the test compound is constructed. The stabilized contraction induced by Arg-vasopressin is defined as 100% tension. The relaxation is expressed as percentage tension.

B-6. In vivo assay for detecting cardiovascular effects: blood pressure measurement in anaesthetized rats (vasopressin 'challenge' model)

Male Sprague-Dawley rats (250-350 g body weight) are used under ketamine/ xylazine/ pentobarbital injection anaesthesia. Polyethylene tubes (PE-50, Intramedic ® ), prefilled with heparin-containing (500 IU/ml) isotonic sodium chloride solution, are introduced into the jugular vein and the femoral vein and then tied in. Arg-vasopressin (SIGMA) is injected via one venous access, with the aid of a syringe; the test substance is administered via the second venous access. For determination of the systolic blood pressure, a pressure catheter (Millar SPR-320 2F) is tied into the carotid artery. The arterial catheter is connected to a pressure transducer which feeds its signals to a recording computer equipped with suitable recording software. In a typical experiment, the experimental animal is administered 3-4 successive bolus injections at intervals of 10- 15 min with a defined amount of Arg-vasopressin (30 ng/kg) in isotonic sodium chloride solution. When the blood pressure has reached initial levels again, the test substance is administered as a bolus, with subsequent continuous infusion, in a suitable solvent. After this, at defined intervals (10-15 min), the same amount of Arg-vasopressin as at the start is administered again. On the basis of the blood pressure values, a determination is made of the extent to which the test substance counteracts the hypertensive effect of Arg-vasopressin. Control animals only receive solvent instead of the test substance.

Following intravenous administration, the compounds of the invention, in comparison to the solvent controls, bring about an inhibition of the blood pressure increase caused by Arg-vasopressin. B-7. In vivo assay for detecting cardiovascular effects: diuresis investigations in conscious rats kept in metabolism cages

Wistar rats (220-450 g body weight) are kept with free access to feed (Altromin) and drinking water. During the experiment, the animals are kept with free access to drinking water for 4 to 8 or up to 24 hours individually in metabolism cages suitable for rats of this weight class (Tecniplast Deutschland GmbH, D-82383 HohenpeiBenberg). At the beginning of the experiment, the animals are administered the test substance in a volume of 1 to 3 ml/kg body weight of a suitable solvent by means of gavage into the stomach. Control animals only receive solvent. Controls and substance tests are carried out in parallel on the same day. Control groups and substance-dose groups each consist of 4 to 8 animals. During the experiment, the urine excreted by the animals is collected continuously in a receiver at the base of the cage. The volume of urine per time unit is determined separately for each animal, and the concentration of urinary electrolytes is measured by standard methods of flame photometry. Before the beginning of the experiment, the body weight of the individual animals is determined.

B-8. In vivo assay for detecting protective renal effects: Acute ischemia/reperfusion injury model in rodents

Laboratory bred male C57B1/6J mice 6-8 weeks old are obtained from Taconic Biosciences, male 6-8 weeks old Sprague Dawley® rat are obtained from Charles River. Both rats and mice are maintained under standard laboratory conditions, 12 hour light-dark cycles with access to normal chow and drinking water at libitum. For the ischemia reperfusion injury model a total of 10-12 rats or mice is used in each control and experimental group.

Animals are anesthetized with continuous inhaled isoflurane. A right nephrectomy is performed through a right flank incision 7 days before the ischemic procedures in the contralateral kidneys. For renal ischemia a left flank incision is made. Renal vessels are exposed by dissection of the left renal pedicle. Non-traumatic vascular clamps are used to stop blood flow (artery and vein) during 45 min (rats) or 25 min (mice) of ischemia. Reperfusion is established by removing the clamps. The abdominal wall (muscular layer and skin) is closed with 5.0 polypropylene sutures. Temgesic® (Buprenorphin, 0.025 mg/kg s.c.) is applied as an analgesic.

Urine of each animal is collected in metabolic cages over night before sacrifice at 24h post ischemia. Upon sacrifice, blood samples are obtained under terminal anesthesia. After centrifugation of the blood samples, serum is isolated. Both serum creatinine and serum urea are measured via clinical biochemistry analyzer (Pentra 400). For the assessment of serum and urinary kidney injury biomarkers (Neutrophil gelatinase-associated lipocalin [NGAL], kidney injury molecule- 1 [KIM-1 ] and Osteopontin) ELlSA's are performed according to the manufacturers protocol. Both urinary creatinine and albumin are measured to determine the albumin/creatinine ratio. Total RNA is isolated from kidneys. Left kidneys are snap-frozen in liquid nitrogen at sacrifice. Kidney tissue is then homogenized and RNA is obtained. Total RNA is transcribed to cDNA. Using TaqMan real-time PCR renal NGAL, Osteopontin, KIM- 1, Nephrin and Podocin mRNA expression is analyzed in whole kidney tissue.

Differences between groups are analyzed by one-way ANOVA with Dunnett's corrections for multiple comparisons. Statistical significance is defined as p < 0.05. All statistical analyses are done using GraphPad Prism 6.

B-9. In vivo assay for detecting cardiovascular effects: hemodynamic investigations in anaesthetized dogs

Male beagle dogs (Beagle, Marshall BioResources, USA) with a weight of between 10 and 15 kg are anesthetized with pentobarbital (30 mg/kg iv, Narcoren®, Merial, Germany) for the surgical interventions and the hemodynamic and functional investigation termini. Pancuroniumbromide (Pancuronium Inresa, Inresa, Germany, 2-4 mg/animal i.v.) serves additionally as a muscle relaxant. The dogs are intubated and ventilated with an oxygen/ambient air mixture (30/70%), about 2,5-4 L/min. Ventilation takes place using a ventilator from GE Healthcare (Avance, Germany) and is monitored using a carbon dioxide analyzer (-Datex Ohmeda). The anesthesia is maintained by continual infusion of pentobarbital (50 μg/kg/min); fentanyl is used as an analgesic (10 μ § ^ § /1ι).

In preparatory interventions, the dogs are fitted with a cardiac pacemaker. At start of experiment, a cardiac pacemaker from Biotronik (Logos®, Germany) is implanted into a subcutaneous skin pocket and is contacted with the heart via a pacemaker electrode (Siello S60®, Biotronik, Germany) which is advanced through the external jugular vein, with illumination, into the right ventricle.

Thereafter accesses are removed and the dog wakes spontaneously from the anesthesia. After a further 7 days, the above-described pacemaker is activated and the heart is stimulated at a frequency of 220 beats per minute.

The actual drug testing experiments take place 28 days after the beginning of pacemaker stimulation, using the following instrumentation:

• Introduction of a bladder catheter for bladder relief and for measuring the flow of urine · Attachment of electrocardiography (ECG) leads to the extremities for ECG measurement

• Introduction of a sheath introducer filled with sodium chloride solution into the femoral artery. This tube is connected to a pressure sensor (Braun Melsungen, Melsungen, Germany) for measuring the systemic blood pressure Introduction of a Millar Tip catheter (type 350 PC, Millar Instruments, Houston, USA) through a port secured in the carotid artery, for measuring cardiac hemodynamics .

Introduction of a Swan-Ganz catheter (CCOmbo 7.5F, Edwards, Irvine, USA) via the jugular vein into the pulmonary artery, for measuring the cardiac output, oxygen saturation, pulmonary arterial pressures and central venous pressure

Siting of a venous catheter in the cephalic vein, for infusing pentobarbital, for liquid replacement and for blood sampling (determination of the plasma levels of substance or other clinical blood values)

Siting of a venous catheter in the saphenous vein, for infusing fentanyl and for administration of substance

Infusion of vasopressin (Sigma) in increasing dosage, up to a dose of 4 mU/kg/min. The pharmacological substances are then tested with this dosage.

The primary signals are amplified if necessary (ACQ7700, Data Sciences International, USA or Edwards-Vigilance-Monitor, Edwards, Irvine, USA) and subsequently fed into the Ponemah system (Data Sciences International, USA) for evaluation. The signals are recorded continuously throughout the experimental period, and are further processed digitally by said software, and averaged over 30 seconds.

Although the invention has been disclosed with reference to specific embodiments, it is apparent that other embodiments and variations of the invention may be devised by others skilled in the art without departing from the true spirit and scope of the invention. The claims are intended to be construed to include all such embodiments and equivalent variations.
