Description:
N-(1 -((PHENYL)SULFONYL)-3-(PYRIDIN-3-YL)-2-OXOINDOLIN-3-YL)-3-(P IPERIDIN-1 -YL)AZETIDINE-1 -CARBOXAMIDE DERIVATIVES AS VASOPRESSINE V1 A AND V1 B RECEPTOR MODULATORS FOR THE TREATMENT OF E.G. DIABETBS AND DEPRESSION

The present invention relates to novel substituted oxindole derivatives, pharmaceutical 5 compositions comprising them, and their use for the treatment of vasopressin-related

disorders.

Vasopressin is an endogenous hormone which exerts various effects on organs and tissues. It is suspected that the vasopressin system is involved in various pathological

10 states such as, for example, heart failure and high blood pressure. At present, three

receptors (Via, Vlb or V3 and V2) via which vasopressin mediates its numerous effects are known. Antagonists of these receptors are therefore being investigated as possible new therapeutic approaches for the treatment of diseases (M. Thibonnier, Exp.Opin.

Invest. Drugs 1998, 7(5), 729-740; T. Ryckmans, Current Opinion in Drug Discovery &

15 Development 13 (2010), 538-547; G. Decaux et al., Lancet 371 (2008), 1624-1632; R.

Lemmens-Gruber, M. Kamyar, Cell. Mol. Life Sci. 63 (2006), 1766-1779). 1-(Het)Arylsulfonyl-1,3-dihydro-2H-indol-2-ones have previously been described as ligands of vasopressin receptors, for example in WO 2005/030755, WO 2006/005609, 20 WO 2006/080574, WO 2008/080970, WO 2008/080971, WO 2008/080972, WO

2008/080973, WO 2009/071687, WO 2009/071689, WO 2009/071690,

WO2009/071691, WO 2009/083559, WO 2010/009775 or WO 2010/142739.

Besides the binding affinity for the vasopressin V1b receptor, further properties may be 25 advantageous for the treatment and/or prophylaxis of vasopressin-related disorders,

such as, for example:

1.) a selectivity for the vasopressin V1b receptor compared with the vasopressin Via receptor, i.e. the quotient of the binding affinity for the Via receptor (Ki(V1a)

30 (determined in the unit "nanomolar (nM)") and the binding affinity for the V1b receptor (Ki(V1b)) (determined in the unit "nanomolar (nM)"). A larger quotient

Ki(V1a)/Ki(V1b) means a greater V1b selectivity; 2. ) a selectivity for the vasopressin V1b receptor compared with the vasopressin V2 receptor, i.e. the quotient of the binding affinity for the V2 receptor (Ki(V2)

(determined in the unit "nanomolar (nM)") and the binding affinity for the V1b receptor (Ki(V1b)) (determined in the unit "nanomolar (nM)"). A larger quotient

Ki(V2)/Ki(V1b) means a greater V1b selectivity;

3. ) a selectivity for the vasopressin Vlb receptor compared with the oxytocin OT receptor, i.e. the quotient of the binding affinity for the OT receptor (Ki(OT)

(determined in the unit "nanomolar (nM)") and the binding affinity for the V1b receptor (Ki(V1b)) (determined in the unit "nanomolar (nM)"). A larger quotient

Ki(OT)/Ki(V1b) means a greater V1b selectivity.

4. ) the metabolic stability, for example determined from the half-lives, measured in vitro, in liver microsomes from various species (e.g. rat or human);

5. ) no or only low inhibition of cytochrome P450 (CYP) enzymes: cytochrome P450 (CYP) is the name for a superfamily of heme proteins having enzymatic activity (oxidase). They are also particularly important for the degradation (metabolism) of foreign substances such as drugs or xenobiotics in mammalian organisms. The principal representatives of the types and subtypes of CYP in the human body are: CYP 1A2, CYP 2C9, CYP 2D6 and CYP 3A4. If CYP 3A4 inhibitors (e.g. grapefruit juice, cimetidine, erythromycin) are used at the same time as medicinal substances which are degraded by this enzyme system and thus compete for the same binding site on the enzyme, the degradation thereof may be slowed down and thus effects and side effects of the administered medicinal substance may be undesirably enhanced;

6. ) a suitable solubility in water (in mg/ml);

7. ) suitable pharmacokinetics (time course of the concentration of the compound of the invention in plasma or in tissue, for example brain). The pharmacokinetics can be described by the following parameters: half-life (in h), volume of distribution (in l'kg- 1), plasma clearance (in l»h-l«kg-l), AUC (area under the curve, area under the concentration-time curve, in ng*h*l-l), oral bioavailability (the dose-normalized ratio of AUC after oral administration and AUC after intravenous administration), the so-called brain-plasma ratio (the ratio of AUC in brain tissue and AUC in plasma);

8.) no or only low blockade of the hERG channel: compounds which block the hERG channel may cause a prolongation of the QT interval and thus lead to serious disturbances of cardiac rhythm (for example so-called "torsade de pointes"). The potential of compounds to block the hERG channel can be determined by means of the displacement assay with radiolabeled dofetilide which is described in the literature (G. J. Diaz et al., Journal of Pharmacological and Toxicological Methods, 50 (2004), 187 199). A smaller IC50 in this dofetilide assay means a greater probability of potent hERG blockade. In addition, the blockade of the hERG channel can be measured by electrophysiological experiments on cells which have been transfected with the hERG channel, by so-called whole-cell patch clamping (G. J. Diaz et al., Journal of

Pharmacological and Toxicological Methods, 50 (2004), 187-199).

It was therefore an object of the present invention to provide compounds for the treatment or prophylaxis of various vasopres sin-related diseases. The compounds were intended to have a high activity and selectivity, especially a high affinity and selectivity vis-a-vis the vasopressin Vlb receptor. In addition, the substance of the invention was intended to have one or more of the aforementioned advantages 1.) to 8.).

Table B

The positions (e.g. 3-/5-/6-) of R 3 are relative to the 2- and 4-positions of radicals R 1 and R 2 and to the 1 -position of the attachment point of the ring to the SO 2 group. The preferred compounds among the compounds I.l to 1.40 mentioned above are those of the formulae I.l, 1.6, 1.11, 1.16, 1.21, 1.26, 1.31 and 1.36, and especially compounds of the formulae I.l, 1.6, 1.16 and 1.21. Particularly preferred are compounds of the formulae I.l and 1.6. In a specific embodiment, the compounds I are selected from the compounds specified in the examples, either as a free base or in form of a pharmaceutically acceptable salt, an N-oxide or a stereoisomer thereof or as their racemate or any other mixture of their steroisomers. The compounds I of the invention have a center of chirality in position 3 of the

2-oxindole ring. The compounds of the invention may therefore be in the form of a 1:1 mixture of enantiomers (racemate) or of a nonracemic mixture of enantiomers in which one of the two enantiomers, either the enantiomer which rotates the plane of vibration of linearly polarized light to the left (i.e. minus rotation) (hereinafter (-) enantiomer) or the enantiomer which rotates the plane of vibration of linearly polarized light to the right (i.e. plus rotation) (hereinafter (+) enantiomer), is enriched, or of substantially enantiopure compounds, that is to say of substantially enantiopure (-) enantiomer or (+) enantiomer. Since the compounds of the invention have a single center of asymmetry and no axis/plane of chirality, a nonracemic mixture can also be defined as a mixture of enantiomers in which either the R or the S enantiomer predominates. Substantially enantiopure compounds can accordingly also be defined as substantially enantiopure R enantiomer or substantially enantiopure S enantiomer.

"Substantially enantiopure compounds" means in the context of the present invention those compounds having an enantiomeric excess (ee; % ee = (R-S)/(R+S) x 100 or (S-R)/(S+R) x 100) of at least 80% ee, preferably at least 85% ee, more preferably at least 90% ee, even more preferably at least 95% ee and in particular at least 98% ee.

In one embodiment of the invention, the compounds of the invention are in the form of substantially enantiopure compounds. Particularly preferred compounds have an enantiomeric excess of at least 85% ee, more preferably of at least 90% ee, even more preferably of at least 95% ee and in particular of at least 98% ee.

The invention thus relates both to the pure enantiomers and to mixtures thereof, e.g. mixtures in which one enantiomer is present in enriched form, but also to the racemates. The invention also relates to the pharmaceutically acceptable salts of the pure enantiomers of compounds I, and the mixtures of enantiomers in the form of the pharmaceutically acceptable salts of compounds I.

Preferred embodiments of the invention are compounds of the formula I as detailed above which are characterized in that they are in optically active form, and the enantiomer of the relevant compound of the formula I is the S-enantiomner, in the form of a free base, or a pharmaceutically acceptable salt thereof.

Particularly preference is given to compounds of the general formula I and their pharmaceutically acceptable salts as detailed above in which the corresponding S- enantiomer is present in an optical purity (enantiomeric excess, ee) of more than 50% ee, particularly preferably of at least 80% ee, more preferably of at least 90% ee and even more preferably of at least 95% ee and in particular of at least 98% ee. Likewise preferred embodiments of the invention are compounds of the general formula I as detailed above which are characterized in that they are in optically inactive form, i.e. in the form of the racemate, or in the form of a pharmaceutically acceptable salt of the racemate. Examples of synthetic routes for preparing the oxindole derivatives of the invention are described below.

The compounds of the invention can be prepared by using methods described in WO 2005/030755, WO 2006/005609 and the other references mentioned in the outset for synthesizing analogous compounds, and the preparation is outlined by way of example in the below synthesis schemes. The variables in these synthetic schemes have the same meanings as in formula I.

As shown in scheme 1, 3-hydroxy-l,3-dihydroindol-2-ones IV can be obtained by addition of metallated heterocycles III onto the 3-keto group of the isatins II. The metallated heterocycles, such as, for example, the corresponding Grignard (Mg) or organyllithium compound III (M = MgX or Li; X = I or Br), can be obtained in any conventional way from halogen or hydrocarbon compounds by reaction with Mg or lithium- organic compounds. Examplary methods are described in Houben-Weyl, Methoden der Organischen Chemie, vol. 13, 1-2, chapter on Mg and Li compounds.

The isatins II are either commercially available or were prepared in analogy to methods described in the literature (Advances in Heterocyclic Chemistry, A.R. Katritzky and A.J. Boulton, Academic Press, New York, 1975, 18, 2-58; J. Brazil. Chem. Soc. 12, 273-324, 2001).

The 3-hydroxyoxindoles IV can be converted into the compounds V which have a leaving group LG' in position 3, where the leaving group LG' is a conventional leaving group such as, for example, chlorine or bromide. The intermediate V with for example LG' = CI can be prepared by treating the alcohol IV with thionyl chloride in the pres- presence of a base such as, for example, pyridine, in a suitable solvent such as, for example, dichloromethane. The compounds V can subsequently be reacted with amines, such as, for example, ammonia, in a substitution reaction to give the amines VI.

In the first variant amines VI are converted into the sulfonylated product VIII by treatment with sulfonyl chlorides VII after deprotonation with a strong base such as, for example, potassium tert-butoxide or sodium hydride in DMF. Sulfonyl chlorides VII employed can either be purchased or be prepared by known processes (for example J. Med. Chem. 40, 1149 (1997)). Compounds VIII are then reacted with carbonic acid halide, such as phenyl chloroformate, in the presence of a base such as, for example, pyridine, to give the corresponding carbamate IX (LG = leaving group; in case of using phenyl chloroformate, LG = phenoxy). As shown in scheme 2, intermediate IX can then be reacted with an appropriate amine X to give directly the compounds of the general formula I; this conversion can be done at room temperature or elevated temperature and with the addition of auxiliary bases such as, for example, triethylamine or diisopropylethylamine. In a second variant compounds of the general formula I are prepared from intermediates IX in a two-step sequence: intermediate IX can be reacted with an appropriate azetidine- 3-one XII or l-(3-azetidinyl)-4-piperidinone XIII employing the same method and conditions as described above to give the corresponding oxo compounds XIV or XV. Reductive amination of compounds XIV or XV with the appropriate amines XVI or XVII then gives the compounds of the general formula I. The latter reaction is carried out in the presence of a suitable reduction agent, e.g. boron-based reduction agent, typically a boronic ester, such as sodium triacetoxyhydroborate, or cyanoborohydride; where appropriate a Lewis acid such as e.g. zinc chloride or titanium isopropoxide is added to the reaction. General examples for reductive amination are described in the literature, e.g. Comprehensive Organic Transformations 2 nd ed, R. Larock, Wiley VCH, 835-846. As shown in scheme 3, in a third variant amines VI are first reacted with a carboonic acid halide, such as phenyl chloroformate, in the presence of a base such as, for example, pyridine, to give the corresponding carbamate XVIII (LG = leaving group; in case of using phenyl chloroformate, LG = phenoxy), and then reacted further with an appropriate amine at room temperature or elevated temperature and with the addition of auxiliary bases such as, for example, pyridine, triethylamine or

diisopropylethylamine.to give intermediate XIX. Sulfonylation of compounds XIX by treatment with sulfonyl chlorides VII after deprotonation with a strong base such as, for example, potassium tert-butoxide or sodium hydride in DMF, then gives the compounds of the general formula I.

If not indicated otherwise, the above-described reactions are generally carried out in a solvent at temperatures between room temperature and the boiling temperature of the solvent employed. Alternatively, the activation energy which is required for the reaction can be introduced into the reaction mixture using microwaves, something which has proved to be of value, in particular, in the case of the reactions catalyzed by transition metals (with regard to reactions using microwaves, see Tetrahedron 2001, 57, p. 9199 ff. p. 9225 ff . and also, in a general manner, "Microwaves in Organic Synthesis", Andre Loupy (Ed.), Wiley- VCH 2002.

The acid addition salts of compounds I are prepared in a customary manner by mixing the free base with a corresponding acid, where appropriate in solution in an organic solvent, for example a lower alcohol, such as methanol, ethanol or propanol, an ether, such as methyl tert-butyl ether or diisopropyl ether, a ketone, such as acetone or methyl ethyl ketone, or an ester, such as ethyl acetate. Routine experimentations, including appropriate manipulation of the reaction conditions, reagents and sequence of the synthetic route, protection of any chemical functionality that may not be compatible with the reaction conditions, and deprotection at a suitable point in the reaction sequence of the preparation methods are within routine tech- niques.

Suitable protecting groups and the methods for protecting and deprotecting different substituents using such suitable protecting groups are well known to those skilled in the art; examples of which may be found in T. Greene and P. Wuts, Protective Groups in Organic Synthesis (3rd ed.), John Wiley & Sons, NY (1999), which is incorporated herein by reference in its entirety. Synthesis of the compounds of the invention may be accomplished by methods analogous to those described in the synthetic scheme described hereinabove and in specific examples. Starting materials, if not commercially available, may be prepared by procedures selected from standard organic chemical techniques, techniques that are analogous to the synthesis of known, structurally similar compounds, or techniques that are analogous to the above described schemes or the procedures described in the synthetic examples section.

When an optically active form of a compound of the invention is required, it may be obtained by carrying out one of the procedures described herein using an optically active starting material (prepared, for example, by asymmetric induction of a suitable reaction step), or by resolution of a mixture of the stereoisomers of the compound or intermediates using a standard procedure (such as chromatographic separation, recrystallization or enzymatic resolution).

Similarly, when a pure geometric isomer of a compound of the invention is required, it may be obtained by carrying out one of the above procedures using a pure geometric isomer as a starting material, or by resolution of a mixture of the geometric isomers of the compound or intermediates using a standard procedure such as chromatographic separation. The present invention moreover relates to compounds of formula I as defined above, wherein at least one of the atoms has been replaced by its stable, non-radioactive isotope (e.g., hydrogen by deuterium, 12 C by 13 C, 14 N by 15 N, 16 0 by 18 0) and preferably wherein at least one hydrogen atom has been replaced by a deuterium atom.

Of course, the compounds according to the invention contain more of the respective isotope than this naturally occurs and thus is anyway present in the compounds I.

Stable isotopes (e.g., deuterium, 13 C, 15 N, 18 0) are nonradioactive isotopes which contain one additional neutron than the normally abundant isotope of the respective atom. Deuterated compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the non deuterated parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al., J. Labelled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol., 77, 79-88 (1999).

Incorporation of a heavy atom, particularly substitution of deuterium for hydrogen, can give rise to an isotope effect that could alter the pharmacokinetics of the drug.

Stable isotope labeling of a drug can alter its physico-chemical properties such as pKa and lipid solubility. These changes may influence the fate of the drug at different steps along its passage through the body. Absorption, distribution, metabolism or excretion can be changed. Absorption and distribution are processes that depend primarily on the molecular size and the lipophilicity of the substance. These effects and alterations can affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction.

Drug metabolism can give rise to large isotopic effect if the breaking of a chemical bond to a deuterium atom is the rate limiting step in the process. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one important exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom will be stronger than the same bond between the light isotope and that atom. In any reaction in which the breaking of this bond is the rate limiting step, the reaction will proceed slower for the molecule with the heavy isotope due to "kinetic isotope effect". A reaction involving breaking a C-D bond can be up to 700 percent slower than a similar reaction involving breaking a C-H bond. If the C-D bond is not involved in any of the steps leading to the metabolite, there may not be any effect to alter the behavior of the drug. If a deuterium is placed at a site involved in the metabolism of a drug, an isotope effect will be observed only if breaking of the C-D bond is the rate limiting step. There is evidence to suggest that whenever cleavage of an aliphatic C-H bond occurs, usually by oxidation catalyzed by a mixed-function oxidase, replacement of the hydrogen by deuterium will lead to observable isotope effect. It is also important to understand that the incorporation of deuterium at the site of metabolism slows its rate to the point where another metabolite produced by attack at a carbon atom not substituted by deuterium becomes the major pathway a process called "metabolic switching". Deuterium tracers, such as deuterium-labeled drugs and doses, in some cases repeatedly, of thousands of milligrams of deuterated water, are also used in healthy humans of all ages, including neonates and pregnant women, without reported incident (e.g. Pons G and Rey E, Pediatrics 1999 104: 633; Coward W A et al., Lancet 1979 7: 13; Schwarcz H P, Control. Clin. Trials 1984 5(4 Suppl): 573; Rodewald L E et al., J. Pediatr. 1989 114: 885; Butte N F et al. Br. J. Nutr. 1991 65: 3; MacLennan A H et al. Am. J. Obstet Gynecol. 1981 139: 948). Thus, it is clear that any deuterium released, for instance, during the metabolism of compounds of this invention poses no health risk.

The weight percentage of hydrogen in a mammal (approximately 9%) and natural abun- dance of deuterium (approximately 0.015%) indicates that a 70 kg human normally contains nearly a gram of deuterium. Furthermore, replacement of up to about 15% of normal hydrogen with deuterium has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann. New York Acad. Sci 1960 84: 736; Czakja D M et al, Am. J. Physiol. 1961 201: 357). Higher deuterium concentrations, usually in excess of 20%, can be toxic in animals. However, acute replacement of as high as 15%-23% of the hydrogen in humans' fluids with deuterium was found not to cause toxicity (Blagojevic N et al. in "Dosimetry & Treatment Planning for Neutron Capture Therapy", Zamenhof R, Solares G and Harling O Eds. 1994. Advanced Medical Publishing, Madison Wis. pp.125- 134; Diabetes Metab. 23: 251 (1997)). Increasing the amount of deuterium present in a compound above its natural abundance is called enrichment or deuterium-enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %. The hydrogens present on a particular organic compound have different capacities for exchange with deuterium. Certain hydrogen atoms are easily exchangeable under physiological conditions and, if replaced by deuterium atoms, it is expected that they will readily exchange for protons after administration to a patient. Certain hydrogen atoms may be exchanged for deuterium atoms by the action of a deuteric acid such as D 2 SO 4 /D 2 O. Alternatively, deuterium atoms may be incorporated in various combinations during the synthesis of compounds of the invention. Certain hydrogen atoms are not easily exchangeable for deuterium atoms. However, deuterium atoms at the remaining positions may be incorporated by the use of deuterated starting materials or intermediates during the construction of compounds of the invention.

Deuterated and deuterium-enriched compounds of the invention can be prepared by using known methods described in the literature. Such methods can be carried out utilizing corresponding deuterated and optionally, other isotope-containing reagents and/or intermediates to synthesize the compounds delineated herein, or invoking standard synthetic protocols known in the art for introducing isotopic atoms to a chemical structure. Relevant procedures and intermediates are disclosed, for instance in Lizondo, J et al., Drugs Fut, 21(11), 1116 (1996); Brickner, S J et al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al, Org Lett, 5(7), 963 (2003); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; US Patent Nos. 7538189; 7534814; 7531685; 7528131; 7521421; 7514068; 7511013; and US Patent Application Publication Nos. 20090137457; 20090131485; 20090131363;

In a further preferred embodiment, the method of the invention serves for the treatment and/or prophylaxis of schizophrenia and/or psychosis. In a further preferred embodiment, the method of the invention serves for the treatment and/or prophylaxis of pain, e.g. acute or chronic pain, preferably chronic pain, especially neuropathic pain. The patient to be treated prophylactically or therapeutically with the method of the invention is preferably a mammal, for example a human or a nonhuman mammal or a nonhuman transgenic mammal. Specifically it is a human. The compounds of the general formula I and their pharmaceutically acceptable salts as detailed above can be prepared by a skilled worker with knowledge of the technical teaching of the invention in implementing and/or in analogous implementation of process steps known per se. The compounds I and/or their pharmaceutically acceptable salts, N-oxides and their stereoisomers are distinguished by having a selectivity for the vasopressin Vlb receptor subtype vis-a-vis at least one of the closely related vasopressin/oxytocin receptor subtypes (for example vasopressin Via, vasopressin V2 and/or oxytocin). Alternatively, or preferably in addition, the compounds I and/or their pharmaceutically acceptable salts, N-oxides and a stereoisomers are distinguished by having an improved metabolic stability.

The metabolic stability of a compound can be measured for example by incubating a solution of this compound with liver microsomes from particular species (for example rat, dog or human) and determining the half-life of the compound under these conditions (RS Obach, Curr Opin Drug Discov Devel. 2001, 4, 36-44). It is possible in this connection to conclude from an observed longer half-life that the metabolic stability of the compound is improved. The stability in the presence of human liver microsomes is of particular interest because it makes it possible to predict the metabolic degradation of the compound in the human liver. Compounds with increased metabolic stability (measured in the liver microsome test) are therefore probably also degraded more slowly in the liver. The slower metabolic degradation in the liver may lead to higher and/or longer-lasting concentrations (active levels) of the compound in the body, so that the elimination half -life of the compounds of the invention is increased. Increased and/or longer-lasting active levels may lead to a better activity of the compound in the treatment or prophylaxis of various vasopres sin-related diseases. In addition, an improved metabolic stability may lead to an increased bioavailability after oral administration, because the compound is subject, after absorption in the intestine, to less metabolic degradation in the liver (so-called first pass effect). An increased oral bioavailability may, owing to an increased concentration (active level) of the compound, lead to a better activity of the compound after oral administration.

The compounds of the invention are effective after administration by various routes. Possible examples are intravenous, intramuscular, subcutaneous, topical, intratracheal, intranasal, transdermal, vaginal, rectal, sublingual, buccal or oral administration, and administration is frequently intravenous, intramuscular or, in particular, oral.

The present invention also relates to pharmaceutical compositions which comprise an effective dose of a compound I of the invention and/or an N-oxide, a stereoisomer and/or a pharmaceutically acceptable salt thereof and suitable pharmaceutical carriers (drug carriers).

These drug carriers are chosen according to the pharmaceutical form and the desired mode of administration and are known in principle to the skilled worker.

The compounds of the invention of the formula I, their N-oxides, steroisomers or optionally suitable salts of these compounds can be used to produce pharmaceutical compositions for oral, sublingual, buccal, subcutaneous, intramuscular, intravenous, topical, intratracheal, intranasal, transdermal, vaginal or rectal administration, and be administered to animals or humans in uniform administration forms, mixed with conventional pharmaceutical carriers, for the prophylaxis or treatment of the above disorders or diseases.

The suitable administration forms (dose units) include forms for oral administration such as tablets, gelatin capsules, powders, granules and solutions or suspensions for oral intake, forms for sublingual, buccal, intratracheal or intranasal administration, aerosols, implants, forms of subcutaneous, intramuscular or intravenous administration and forms of rectal administration. The compounds of the invention can be used in creams, ointments or lotions for topical administration.

In order to achieve the desired prophylactic or therapeutic effect, the dose of the active ingredient can vary between 0.01 and 50 mg per kg of body weight and per day.

Each unit dose may comprise from 0.05 to 5000 mg, preferably 1 to 1000 mg, of the active ingredient in combination with a pharmaceutical carrier. This unit dose can be administered once to 5 times a day, so that a daily dose of from 0.5 to 25 000 mg, preferably 1 to 5000 mg, is administered.

If a solid composition is prepared in the form of tablets, the active ingredient is mixed with a solid pharmaceutical carrier such as gelatin, starch, lactose, magnesium stearate, talc, silicon dioxide or the like.

The tablets can be coated with sucrose, a cellulose derivative or another suitable substance or be treated otherwise in order to display a sustained or delayed activity and to release a predetermined amount of the active ingredient continuously. A preparation in the form of gelatin capsules is obtained by mixing the active ingredient with an extender and including the resulting mixture in soft or hard gelatin capsules.

A preparation in the form of a syrup or elixir or for administration in the form of drops may contain active ingredients together with a sweetener, which is preferably calorie- free, methylparaben or propylparaben as antiseptics, a flavoring and a suitable coloring substance.

Water-dispersible powders or granules may comprise the active ingredients mixed with dispersants, wetting agents or suspending agents, such as polyvinylpyrrolidones, and sweeteners or masking flavors.

Rectal or vaginal administration is achieved by using suppositories which are prepared with binders which melt at rectal temperature, for example cocoa butter or polyethylene glycols. Parenteral administration is effected by using aqueous suspensions, isotonic saline solutions or sterile and injectable solutions which comprise pharmacologically acceptable dispersants and/or wetting agents, for example propylene glycol or polyethylene glycol.

The active ingredient may also be formulated as microcapsules or centrosomes, if suitable with one or more carriers or additives.

The compositions of the invention may, in addition to the compounds of the invention, comprise other active ingredients which may be beneficial for the treatment of the disorders or diseases indicated above.

The present invention thus further relates to pharmaceutical compositions in which plurality of active ingredients are present together, where at least one of these is a compound I of the invention, or salt thereof.

The invention is explained in more detail below by means of examples, but the examples are not to be understood to be restrictive.

The compounds of the invention can be prepared by various synthetic routes. The methods mentioned, as described accordingly in synthesis schemes 1, 2 and 3, are explained in greater detail merely by way of example using the given examples without being exclusively restricted to synthesis route 1,2 or 3 or analogous methods.

III. DETERMINATION OF THE BIOLOGICAL ACTIVITY 1. Vasopressin Vlb receptor binding assay: Substances:

The test substances were dissolved in a concentration of 5 mM in 100% DMSO and further diluted to 5xl0 "4 M to 5xl0 ~9 M. These serial DMSO predilutions were diluted 1:10 with assay buffer. The substance concentration was further diluted 1:5 in the assay mixture resulting in 2% DMSO in the mixture. All dilutions were performed in a Biomek NX automation workstation (Beckman)

Membrane preparation:

CHO-K1 cells with stably expressed human vasopressin Vlb receptor (clone 3H2) were harvested and homogenized in 50 mM Tris-HCl and in the presence of protease inhibitors (Roche complete Mini # 1836170) using a Polytron homogenizer at intermediate setting for 2 x 10 seconds, and subsequently centrifuged at 40 000 x g for 1 h. The membrane pellet was again homogenized and centrifuged as described and subsequently taken up in 50 mM Tris-HCl, pH 7.4, homogenized and stored in aliquots frozen in liquid nitrogen at -190°C.

Binding assay:

The binding assay was carried out by the method based on that of Tahara et al. (Tahara A et al., Brit. J. Pharmacol. 125, 1463-1470 (1998)).

The incubation buffer was: 50 mM Tris, 10 mM MgCl 2 , 0.1% BSA, pH 7.4.

In the assay mixture (200 μΐ), membranes (26 μg protein in incubation buffer) from CHO- 1 cells with stably expressed human Vlb receptors (cell line hVlb_3H2_CHO) were incubated with 1.5 nM 3 H-AVP (8-Arg-vasopressin, PerkinElmer, NET 800) in incubation buffer (50 mM Tris, 10 mM MgCl 2 , 0.1% BSA, pH 7.4) (total binding) or additionally with increasing concentrations of test substance (displacement experiment). The nonspecific binding was determined with 1 μΜ AVP (Fluka 94836). All determinations were carried out as duplicate determinations. After incubation

(60 minutes at room temperature), the free radioligand was filtered off by vacuum filtration (Tomtec Mach III) through Wathman GF/B glass fiber filter plates (UniFilter, PerkinElmer 6005177). The liquid scintillation measurement took place in a Microbeta TriLux 12 (Wallac).

Analysis:

The binding parameters were calculated by nonlinear regression in SAS. The algorithms of the program operate in analogy to the LIGAND analysis program (Munson PJ and Rodbard D, Analytical Biochem. 107, 220-239 (1980)). The Kd of 3 H-AVP for the recombinant human Vlb receptors is 0.4 nM and was used to determine the Ki. 2. Vasopressin Via receptor binding assay:

Substances:

The test substances were dissolved in a concentration of 5 mM M in DMSO. Further dilution of these DMSO solutions took place as described for Vlb.

Membrane preparation:

CHO-K1 cells with stably expressed human vasopressin Via receptor (clone 5) were harvested and homogenized in 50 mM Tris-HCl and in the presence of protease inhibitors (Roche complete Mini # 1836170) using a Polytron homogenizer at intermediate setting for 2 x 10 seconds, and subsequently centrifuged at 40 000 x g for 1 h. The membrane pellet was again homogenized in a High-Pressure-Homogenizer, Polytec 50K at 1500 PSI (Heinemann, Germany) and subsequently taken up in 50 mM Tris-HCl, pH 7.4, homogenized and stored in aliquots frozen in liquid nitrogen at -190°C.

Binding assay:

The binding assay was carried out by the method based on that of Tahara et al. (Tahara A et al., Brit. J. Pharmacol. 125, 1463-1470 (1998)).

The incubation buffer was: 50 mM Tris, 10 mM MgCl 2 , 0.1% BSA, pH 7.4.

In the assay mixture (200 μΐ), membranes (40 μg protein in incubation buffer) from

CHO-K1 cells with stably expressed human Via receptors (cell line hVla_5_CHO) were incubated with 0.04 nM 125 I-AVP (8-Arg-vasopressin, PerkinElmer NEX 128) in incubation buffer (50 mM Tris, 10 mM MgCl 2 , 0.1% BSA, pH 7.4) (total binding) or additionally with increasing concentrations of test substance (displacement experiment). The nonspecific binding was determined with 1 μΜ AVP (Fluka 94836). Duplicate determinations were carried out.

After incubation (60 minutes at room temperature), the samples were processed as described for Vlb.

Analysis: The binding parameters were calculated by nonlinear regression in SAS. The algorithms of the program operate in analogy to the LIGAND analysis program (Munson PJ and Rodbard D, Analytical Biochem. 107, 220-239 (1980)). The Kd of 125 I-AVP for the recombinant hVla receptors was determined in saturation experiments. A Kd of 1.33 nM was used to determine the Ki.

3. Oxytocin receptor binding assay

Substances:

The substances were dissolved in a concentration of 5 mM in DMSO and diluted further as described for Vlb.

Membrane preparation:

Confluent HEK-293 cells with transiently expressing recombinant human oxytocin receptors were harvested and centrifuged at 750 x g at room temperature for 5 minutes. The pellet was taken up in ice-cold lysis buffer (50 mM Tris-HCl, 10% glycerol, pH 7.4 and Roche complete protease inhibitor) and thereby subjected to an osmotic shock at 4°C for 20 minutes. Lysed cells were then centrifuged at 750 x g at 4°C for 20 minutes, the pellet was taken up in incubation buffer (50 mM Tris, 10 mM MgCl 2 , 0.1% BSA, pH 7.4), and aliquots corresponding to 10 7 cells/ml were prepared. The aliquots were frozen at -80°C until use.

Binding assay:

On the day of the experiment, the cell lysate was thawed, homogenized, and diluted with incubation buffer (50 mM Tris, 10 mM MgCl 2 , 0.1% BSA, pH 7.4) to the desired concentration. The reaction mixture of 0.200 ml was composed of cell lysate corresponding to 5xl0 4 cells (HEK-293 cells expressing transiently human OT receptors) and 1 nM 3H-oxytocin (PerkinElmer NET858) in the presence of test substance (displacement experiment) or incubation buffer only (total binding). The nonspecific binding was determined in the presence of 1 μΜ oxytocin (Bachem AG, H2510). Determinations were carried out in duplicates. After 60 minutes incubation at room temperature, bound and free radioligand were separated by filtration under vacuum on GF/B UniFilter plates (Perkin Elmer # 6005177) pre-incubated with 0.3% PEL The bound radioactivity was determined by liquid scintillation measurement in a

Microbeta (Perkin Elmer) plate counter.

Analysis:

The binding parameters were calculated by nonlinear regression analysis (SAS) in analogy to the LIGAND program of Munson and Rodbard (Analytical Biochem 1980; 107: 220-239). The Kd of 3 H-oxytocin for the recombinant hOT receptors was 7.6 nM and was used to calculate the Ki from competition binding experiments.

4. Determination of the microsomal half-life:

The metabolic stability of the compounds of the invention was determined in the following assay.

The test substances were incubated in a concentration of 0.5 μΜ as follows:

0.5 μΜ test substance are preincubated together with liver microsomes from different species (from rat, human or other species) (0.25 mg of microsomal protein/ml) in 0.05 M potassium phosphate buffer of pH 7.4 in micro titer plates at 37 °C for 5 min. The reaction is started by adding NADPH (1 mg/mL). After 0, 5, 10, 15, 20 and 30 min, 50 μΐ aliquots are removed, and the reaction is immediately stopped and cooled with the same volume of acetonitrile. The samples are frozen until analyzed. The remaining concentration of undegraded test substance is determined by MSMS. The half-life (Tl/2) is determined from the gradient of the signal of test substance/unit time plot, it being possible to calculate the half-life of the test substance, assuming first order kinetics, from the decrease in the concentration of the compound with time. The microsomal clearance (mCl) is calculated from mCl = ln2/Tl/2 / (content of microsomal protein in mg/ml) x 1000 [ml/min/mg] (modified from references: Di, The Society for Biomoleculur Screening, 2003, 453-462; Obach, DMD, 1999 vol 27. N 11, 1350-1359).

5. Methods for in vitro determination of the cytochrome P450 (CYP) inhibition

Luminescent substrates for 2C9 and 3A4:

0.4 mg/ml human liver microsomes are preincubated with the test substances to be investigated (0-20 μΜ), the CYP-specific substrates, in 0.05 M potassium phosphate buffer of pH 7.4 at 37°C for 10 min. The Cyp-specific substrate for CYP 2C9 is lucifer- luciferin H, and for CYP 3A4 is luciferin BE. The reaction is started by adding

NADPH. After incubation at RT for 30 min, the luciferin detection reagent is added, and the resulting luminescence signal is measured (modified from reference: Promega, Technical Bulletin P450-GLO™ Assays).

Midazolam CYP 3A4 time-dependent inhibition

The assay consists of 2 parts. Firstly, the test substance is preincubated with the liver microsomes (with NADPH = preincubation, then addition of the substrate; in the second part the substrate and the test substance are added simultaneously = coincubation.

Preincubation:

0.05 mg/ml microsomal protein (human liver microsomes) are preincubated with 0- 10 μΜ (or 50 μΜ) test substance in 50 mM potassium phosphate buffer for 5 min. The reaction is started with NADPH. After 30 min 4 μΜ midazolam (final concentration) are added, and incubation is continued for 10 min. 75 μΐ of the reaction solution are removed after 10 min, and stopped with 150 μΐ of acetonitrile solution.

Coincubation:

0.05 mg/ml microsomal protein (human liver microsomes) are preincubated with 4 μιη midazolam (final concentration) and 0-10 μΜ (or 50 μΜ) test substance in 50 mM potassium phosphate buffer for 5 min. The reaction is started with NADPH. 75 μΐ of the reaction solution are removed after 10 min and stopped with 150 μΐ of acetonitrile solution. The samples are frozen until the MSMS analysis (modified from references: Obdach, Journal of Pharmacology & Experimental Therapeutics, Vol 316, 1, 336-348, 2006; Walsky, Drug Metabolism and Disposition Vol 32, 6, 647-660, 2004).

Method for determining the solubility in water (in mg/ml) The solubility in water of the compounds of the invention can be determined for example by the so-called shake flask method (as specified in ASTM International: E 1148-02, Standard test methods for measurement of aqueous solubility, Book of Standards Volume 11.05.). This entails an excess of the solid compound being put into a buffer solution with a particular pH (for example phosphate buffer of pH 7.4), and the resulting mixture being shaken or stirred until equilibrium has been set up (typically 24 or 48 hours, sometimes even up to 7 days). The undissolved solid is then removed by filtration or centrifugation, and the concentration of the dissolved compound is determined by UV spectroscopy or high pressure liquid chromatography (HPLC) by means of an appropriate calibration plot.

7. Results The results of the receptor binding investigations are expressed as receptor binding constants [K ; (Vlb)] or selectivities [Ki(Vla)/Ki(Vlb)]. The results of the investigation of the metabolic stability are indicated as microsomal clearance (mCl).

The compounds of the invention show very high affinities for the Vlb receptor in these assays (maximally 100 nM, or maximally 10 nM, frequently < 1 nM). The compounds also show high selectivities vis-a-vis the Via receptor and a good metabolic stability, measured as microsomal clearance.

The results are listed in table C. The numbers of the compounds refer to the synthesis examples.
