Description
Substituted 2-(chroman-6-yloxy)-thiazoles and their use as pharmaceuticals
The présent invention relates to substituted 2-(chroman-6-yloxy)-thiazoles ofthe formula I,
R4 in which Ar, R2, R3 and R4 are as defined below. The compounds of the formula I are inhibitors of the sodium-calcium exchanger (NCX), especially of the sodiumcalcium exchanger of subtype 1 (NCX1 ), and are suitable for the treatment of diverse disorders in which intracellular calcium homeostasis is disturbed, such as arrhythmias, heart failure and stroke. The invention furthermore relates to processes for the préparation of the compounds of the formula I, their use as pharmaceuticals, and pharmaceutical compositions comprising them.
Over the last decade major pharmacologie advances hâve been realized in the management of heart failure (HF), or congestive heart failure (CHF). Beta-blockers and inhibitors of the renin-angiotensin-aldosterone system hâve been found to hâve a favorable effect in CHF with regard to mortality and improvement of symptoms (K. Dickstein et al., Eur. J. Heart Fail. 10 (200Θ): 933-989). Nevertheless, morbidity and mortality hâve remained unacceptably high. The number of patients with CHF, and in · particular more severe forms of CHF, is even growing, in part paradoxically because of the success of these treatment approaches. Thus, there is still a need for agents that can help improve CHF outcome and enhance quality of life. Blockers ofthe sodium-calcium exchanger (NCX), a transport protein which is involved in the régulation of cellular calcium and sodium levels, hâve the potential to improve the prognosis of CHF and quality of life.
The function of the NCX is to extrude calcium in cardiomyocytes and other cell types such as neurons. In CH F, the NCX was shown to be upregulated, thus unloading the cell from calcium and further decreasing myocardial contractility (M. Flesch et al., Circulation 94 (1996): 992-1002; G. Hasenfuss et al., Circulation 99 (1999): 641-648). Pump failure in CHF is not only due to irréversible structural changes and loss of myocardium, but also due to adverse functionai changes including a disturbance of the intracellular calcium homeostasis. The latter can be treated by inhibition of the NCX. Three subtypes of the NCX hâve been described. In the heart, predominantly subtype 1 is expressed.
Through the NCX, calcium is exchanged for sodium, and extracellular sodium is the driving force for the exchanger. The stoichiometry of the exchanger is that three sodium ions enter the cell for the extrusion of one calcium ion. This stoichiometry causes a positive inward current which is depolarizing in nature. The depolarizing current, if of a sufficient size, gives rise to a certain type of arrhythmias which is called delayed afterdepolarizations (DADs) (D. M. Bers et al., Ann. N. Y. Acad. Sci. 1080 (2006): 165-177; K. R. Sipido et al., Pflugers Arch. 430 (1995): 871-878; A. O. Verkerk et al., Circulation 104 (2001): 2728-2733). This type of arrhythmias is also called triggered activity. The prématuré beats arising from the NCX-induced depolarizing currents can cause more complex and irréversible arrhythmias such as épisodes of tachycardia, ventricular flutter or ventricular fibrillation.
Patients with pump failure, or heart failure, typically suffer from arrhythmias and arrhythmic death. About 50% of the mortality in CHF is due to arrhythmic death. NCX blockade is therefore a means of improving pump failure and associated symptoms as well as of reducing arrhythmic death. Current positive inotropic drugs are associated with proarrhythmic effects that either increase mortality, such as in the case of phosphodiesterase inhibitors, or annihilate the positive effects achieved by an improvement of pump failure by the positive inotropic effect (J. T. Parissis et al., Curr. Opin. Crit. Care 16 (2010): 432-441). On the other hand, a number of clinically useful antiarrhythmic drugs hâve a négative inotropic effect on the heart worsening the symptoms of heart failure. NCX blockers are therapeutically unique in that they can address the two major problems of CHF, pump failure and arrhythmias.
NCX biockade is particularly interesting for advanced stages of CHF, like NYHA Classes III and IV according to the New York Heart Association Functional Classification of heart failure, in which the therapeutic options, i.e. beta-blockers, inhibitors of the renin angiotensin-aldosterone system, diuretics and vasodilators, already are fully exploited. Elderly patients progressing to end-stage HF présent a new emerging population. In this late stage a vasodilator effect is no more désirable in a considérable part of the patients because blood pressure is already lowered as a conséquence of pump failure. Phosphodiesterase inhibitors as positive inotropic drugs not only suffer from the drawback of being proarrhythmic, but also from a vasodilator effect.
Atrial fibrillation (AF) is the most frequent arrhythmia. AF affects about 6.8 million patients in the US and the European Union, and its prevalence is strongly rising because of the aging of the population and of the successful treatment of myocardial infarction, coronary artery disease and congestive heart failure. AF causes about 25 % of ail strokes, and increases mortality. Also in AF, upregulation of the NCX has been demonstrated (U. Schotten et al., Cardiovasc. Res. 53 (2002): 192-201). Upregulation of the NCX can be involved in the induction of AF by the arrhythmogenic activity of the NCX and in its maintenance, and hence NCX blockers have therapeutically favorable effects in the therapy and prévention of AF. Since AF is an increasing disease in the aging population and is frequently associated with heart failure in up to about 45% of patients (I. Savelieva et al., Europace. 5 Suppl 1 (2004): S5-S19), NCX blockers would be particularly favorable in patients with AF and CHF.
Since NCX blockers also exert a positive inotropic effect in the atria, they may be particularly favorable in diastolic heart failure where ventricular filling is the major problem as a conséquence of ventricular stiffening. A more vigorous atrial contraction would improve ventricular filling in diastolic heart failure.
Since a reduced cardiac output has deleterious effects on the perfusion of organs such as the kidney, brain and heart, inhibition of the NCX, which increases the contractility of the heart, is able to improve perfusion of the brain, heart and kidney for a therapy or prévention of stroke, dementia and Alzheimer's disease, rénal failure and cardiac ischemia. Since the NCX is also involved in sait sensitive hypertension, its inhibition is also suited for the treatment of hypertension.
Inhibitors of the NCX are also suited for the therapy and prévention of life threatening conditions in which ionotropic support is required to maintain a sufficient level of blood supply. This includes ail forms of shock, hémodynamie shock, cardiogenic shock and septic shock. Inhibitors of the NCX are particularly suited to treat these conditions because they are neutral on heart rate and lack the proarrhythmic or vasodilator or vasoconstrictor properties of other inotropic drugs.
In stroke, NCX blockers hâve the potential of improving the outcome since in neuronal hypoxia, as occurs in stroke, the NCX reverses its transport direction to reverse mode, and loads the cells with calcium leading to a calcium overload. This leads to accelerated cell death due to excessive intracellular calcium concentrations. Moreover, a low cardiac output can lead to brain ischemia favoring stroke. NCXblockers will increase cardiac output and raise brain perfusion. Hence, NCX-blockers hâve a potential in the therapy and prévention of stroke (T. Matsuda et al., J. Pharmacol. Exp. Ther. 298 (2001 ): 249-2569.
Certain compounds capable of inhibiting the NCX hâve already been described, e.g. in EP 0978506, JP 2008/189592, WO 2004/000813, WO 2004/063191, WO 03/006452, WO 02/32883, WO 97/09306. However, there still is a need for further compounds which inhibit the NCX and are suitable for use as pharmaceuticals in the treatment of the mentioned disease states. It has now been found that the compounds of the formula I are excellent inhibitors of the sodium-calcium exchanger (NCX), especially ofthe sodium-calcium exchanger of subtype 1 (NCX1), and hâve a favorable property profile for such use.
Thus, a subject ofthe présent invention are the compounds of the formula I, in any of their stereoisomeric forms and mixtures of stereoisomeric forms in any ratio, and the pharmaceutically acceptable salts thereof,

The groups R2 and R3 in the compounds of the formula I and ail other compounds in which the groups R2 and R3 occur and in the respective formulae are not bonded to a spécifie ring atom, can be bonded to any of the two carbons atom of the thiazole ring system depicted in formula I which hâve a free binding site, i.e. to the carbon atoms in ring positions 4 and 5 of the thiazole ring system, as is indicated by the bonds originating at R2 and R3 which are not directed to a spécifie carbon atom. One of the groups R2 and R3 is bonded to the carbon atom in ring position 4 of the thiazole ring system, and the other of the groups R2 and R3 is bonded to the carbon atom in ring position 5 of the thiazole ring system. This applies accordingly to other groups in compounds referred to herein whose binding position is not fixed in their formulae, such as the group Y in the compounds ofthe formulae III and IV, for example.
Likewise, groups R4 in the compounds of the formula I and ail other compounds in which groups R4 occur, which are different from hydrogen, can be bonded to any carbon atoms of the chroman ring system depicted in formula I which hâve a free binding site, i.e. to carbon atoms in ring positions 2, 3, 4, 5, 7 and 8 of the chroman ring system, as is indicated by the bond originating at R4 which is not directed to a spécifie carbon atom of the chroman ring. In ail free bonding sites of the carbons atom in ring positions 2, 3, 4, 5, 7 and 8 of the chroman ring system which are not occupied by groups R4 different from hydrogen, hydrogen atoms are présent, I.e., if in a compound of the formula I no group R4 is présent which is different from hydrogen, the carbon atoms in ring positions 2, 5, 7 and 8 of the chroman ring System carry one hydrogen atom, and the carbon atoms in ring positions 3 and 4 of the chroman ring system carry two hydrogen atoms. If substituents R4 are présent,
1. e. atoms or groups representing R4 which are different from hydrogen, one or more of the said hydrogen atoms are replaced by the substituents R4.
If structural éléments such as groups, substituents or numbers, for example, can occur several times in the compounds of the formula I, they are ail independent of each other and can in each case hâve any of the indicated meanings, and they can in each case be identical to or different from any other such element In a dialkylamino group, for example, the alkyl groups can be identical or different.
Alkyl groups, i.e. saturated hydrocarbon residues, can be linear (straight-chain) or branched. This also applies if these groups are substituted or are part of another group, for example an alkyl-O- group (alkyloxy group, alkoxy group) or an HOsubstituted alkyl group (HO-alkyl-, hydroxyalkyl group). Depending on the respective définition, the number of carbon atoms in an alkyl group can be 1,2, 3, 4, 5 or 6, or 1,
2, 3 or 4, or 1, 2 or 3, or 1 or 2, or 1. Examples of alkyl are methyl, ethyl, propyl including n-propyl and isopropyl, butyl including n-butyl, sec-butyl, isobutyl and tertbutyl, pentyl including n-pentyl, 1-methylbutyl, isopentyl, neopentyl and tert-pentyl, and hexyl including n-hexyl, 3,3-dimethylbutyl and isohexyl. Examples of alkyl-O- groups are methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, isobutoxy, tert-butoxy, n-pentoxy. Examples of aîkyl-S(O)n- are methylsulfanyl- (CH3-S-), methanesulfinyl- (CH3-S(O)-), methanesulfonyl (CH3-S(O)2-), ethylsulfanyl(CHa-CHz-S-), ethanesulfînyl- (CH3-CH2-S(O)-), ethanesulfonyl (CH3-CH2-S(O)2-), 1-
Ψ L methylethylsulfanyl- ((CHshCH-S-), 1 -methylethanesulfinyl- ((CH3)2CH-S(O)-), 1methylethanesulfonyl ((CH3)2CH-S(O)2-). In one embodiment of the invention, the number n is selected from the sériés consisting of 0 and 2, wherein ail numbers n are independent of each other and can be identical or different In another embodiment the number n in any of its occurrences, independent of its meaning in other occurrences, is 0. In another embodiment the number n in any of its occurrences is, independent of its meaning in other occurrences, 2.
A substituted alkyl group can be substituted in any positions, provided that the respective compound is sufficiently stable and is suitable as a pharmaceutical active compound. The prerequisite that a spécifie group and a compound of the formula I are sufficiently stable and suitable as a pharmaceutical active compound, applies in general with respect to the définitions of ail groups in the compounds of the formula I. As examples of substituted alkyl groups, specifically of HO-(CrC4)-alkyl groups, for example, hydroxymethyl, 1 -hydroxyethyl, 2-hydroxyethyl, 1 -hydroxypropyl, 2hydroxypropyl, 3-hydroxypropyl, 1-hydroxy-1-methylethyl, 2-hydroxy-1-methylethyl, 1-hydroxybutyl, 4-hydroxybutyl, 2-hydroxy-1-methylpropyl or 2-hydroxy-1methylpropyl may be mentioned. An alkyl group which, independently of any other substituents, can be substituted by one or more fluorine substituents, can be unsubstituted by fluorine substituents, i.e. not carry fluorine substituents, or substituted, for example by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11 fluorine substituents, or by 1, 2, 3, 4 or 5 fluorine substituents, or by 1, 2 or 3 fluorine substituents, which can be located in any positions. For example, in a fluoro-substituted alkyl group one or more methyl groups can carry three fluorine substituents each and be présent as trifluoromethyl groups, and/or one or more methylene groups (CH2) can carry two fluorine substituents each and be présent as difluoromethylene groups. The explanations with respect to the substitution of a group by fluorine also apply if the group additionally carries other substituents and/or is part of another group, for example of an alkyl-O- group. Examples of fluoro-substituted alkyl groups are trifluoromethyl, 2-fluoroethyl, 1-fluoroethyl, 1,1-difluoroethyl, 2,2,2-trifluoroethyl, pentafluoroethyl, 3,3,3-trifluoropropyl, 2,2,3,3,3-pentafluoropropyl, 4,4,4-trifluorobutyl and heptafluoroisopropyl. Examples of fluoro-substituted alkyl-O- groups are
K trifluoromethoxy, 2,2,2-trifluoroethoxy, pentafluoroethoxy and 3,3,3-trifluoropropoxy. Examples of fluoro-substituted alkyl-S(O)n- groups are trifluoromethylsulfanyl(CF3-S-), trifluoromethanesulfinyl- (CF3-S(O)-) and trifluoromethanesulfonyl (CF3-S(O)2-). With respect to ail groups or substituents in the compounds of the formula I which can be an alkyl group which can generally contain one or more fluorine substituents, as an example of groups or substituents containing fluorinesubstituted alkyl which may be included in the définition of the group or substituent, the group CF3 (trifluoromethyl), or respective groups such as CF3-O- or CF3-S-, may be mentioned.
The above explanations with respect to alkyl groups apply correspondingly to alkyl groups which in the définition of a group in the compounds of the formula I are bonded to two adjacent groups, or linked to two groups, and may be regarded as divalent alkyl groups (alkanediyl groups), like in the case of the alkyl part of a substituted alkyl group. Thus, such groups can also be linear or branched, the bonds to the adjacent groups can be located in any positions and can start from the same carbon atom or from different carbon atoms, and they can be unsubstituted or substituted by fluorine substituents independently of any other substituents. Examples of such divalent alkyl groups are -CH2-, -CH2-CH2-, OH2-CH2“CH2-CH2-CH2-CH2-CH2-, -CH(CH3)-, -C(CH3)2- -CH(CH3)-CH2-, -CH2-CH(CH3)-, -C(CH3)2-CH2-, -CH2-C(CH3)2- Examples of fluoro-substituted alkanediyl groups, which can contain 1, 2, 3, 4, 5 or 6 fluorine substituents, for example, are -CHF-, -CF2-, -CF2-CH2-, -CH2-CF2-, -CF2-CF2-, -CF(CH3)-, -C(CF3)2-, -C(CH3)2-CF2-, -CF2-C(CH3)2-.
The number of ring carbon atoms in a (C3-C7)-cycloalkyl group can be 3, 4, 5, 6 or 7. Examples of cycloalkyi are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl. The number of ring carbon atoms in a (Ce-Cio)-bicycloalkyl group can be 6, 7, 8, 9 or 10. The two cycles in a bicycloalkyl group can hâve one, two to more ring carbon atoms in common and can be fused or form a bridged bicycle or a spirocycle. Examples of bicycloalkyl are bicyclo[2.1.1]hexyl, bicyclo[2.2.1 jheptyl, bicyclo[3.1.1 jheptyl, bicyclo[2.2.2]octyl, bicyclo[3.2.1 Joctyl, bicyclo[3.2.2]nonyl and
K bicyclo[4,4.0]decyl. Bicycloalkyl groups can be bonded via any ring carbon atom. Cycloalkyl and bicycloalkyl groups which, independently of any other substituents, can be substituted by one or more (Ci-C^-J-alkyl substituents, can be unsubstituted by alkyl substituents, i.e. not carry alkyl substituents, or substituted, for example by 1, 2, 3 or 4 identical or different (Ci-C4)-alkyl substituents, for example by methyl groups, which substituents can be located in any positions. Examples of such alkylsubstituted cycloalkyl groups and bicycloalkyl groups are 1-methylcyclopropyl, 2,2dimethylcyclopropyl, 1-methylcyclopentyl, 2,3-dimethylcyclopentyl, 1methylcyclohexyl, 4-methylcyclohexyl, 4-isopropylcyclohexyl, 4-tert-butylcyclohexyl,
3,3,5,5-tetramethylcyclohexyl, 7,7-dimethylbicyclo[2.2.1]heptyl, 6,6dimethylbicyclo[3.1.1 Jheptyl and 1,7,7-trimethylbicyclo[2.2.1 jheptyl. Cycloalkyl groups and bicycloalkyl groups which, independently of any other substituents, can be substituted by one or more fluorine substituents, can be unsubstituted by fluorine substituents, i.e. not carry fluorine substituents, or substituted, for example by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11 fluorine substituents, or by 1, 2, 3, 4, 5 or 6 fluorine substituents, or by 1, 2 or 3 fluorine substituents. The fluorine substituents can be located in any positions of the cycloalkyl group or bicycloalkyl groups and can also be located in an alkyl substituent. Examples of fluoro-substituted cycloalkyl groups and bicyloalkyl groups are 1-fluorocyclopropyl, 2,2-difluorocyclopropyl, 3,3difluorocyclobutyl, 1-fluorocyclohexyl, 4,4-difluorocyclohexyl, 3,3,4,4,5,5hexafluorocyclohexyl, 1-fluorobicyclo[2.2.2]octyl and 1,4-difluorobicyclo[2.2.2]octyl. Cycloalkyl groups can also be substituted simultaneously by fluorine and alkyl. Examples of the group (C3-C7)-cycloalkyl-(Ci-C4)-alkyl- are cyclopropylmethyl-, cyclobutylmethyl-, cyclopentylmethyl-, cyclohexylmethyl-, cycloheptylmethyl-, 1cyclopropylethyl-, 2-cyclopropylethyl-, 1 -cyclobutylethyl-, 2-cyclobutylethyl-, 1 cyclopentylethyl-, 2-cyclopentylethyl-, 1-cyclohexylethyl-, 2-cyclohexylethyl-, 1cycloheptylethyl-, 2-cycloheptylethyl-, In one embodiment ofthe invention, a (C3-C7)cycloalkyl-(CrC4)-alkyl- group in any one or more occurrences of such a group, independently of any other occurrences, is a (C3-C7)-cycloalkyl-(Ci-C2)-alkyl- group, in another embodiment a (C3-C7)-cycloalkyl-CH2- group. In the group (C3-C7)cycloalkyl-(Ci-C4)-alkyl-, and likewise in ail other groups, the terminal hyphen ? <16755 dénotés the free bond via which the group is bonded, and thus indicates via which subgroup a group composed of subgroups is bonded.
In substituted phenyl groups, induding phenyl groups representing Ar and RI4, the substituents can be located in any positions. In monosubstituted phenyl groups, the substituent can be located in position 2, in position 3 or in position 4. In disubstituted phenyl groups, the substituents can be located in positions 2 and 3, in positions 2 and 4, in positions 2 and 5, in positions 2 and 6, in positions 3 and 4, or in positions 3 and 5. In trisubstituted phenyl groups, the substituents can be located in positions 2, 3 and 4, in positions 2, 3 and 5, in positions 2, 3 and 6, in positions 2, 4 and 5, in positions 2, 4 and 6, or in positions 3, 4 and 5. If a phenyl group carries four substituents, some of which can be fluorine atoms, for example, the substituents can be located in positions 2, 3, 4 and 5, in positions 2, 3, 4 and 6, or in positions 2, 3, 5 and 6. If a polysubstituted phenyl group or any other polysubstituted group carries different substituents, each substituent can be located in any suitable position, and the présent invention comprises ail positional isomers. The number of substituents in a substituted phenyl group can be 1, 2, 3, 4 or 5. In one embodiment of the invention, the number of substituents in a substituted phenyl group, like the number of substituents in any other substituted group which can carry one or more substituents, is 1, 2, 3 or 4, in another embodiment 1, 2 or 3, in another embodiment 1 or 2, in another embodiment 1, where the number of substituents in any occurrence of such a substituted group is independent of the number of substituents in other occurrences.
In heterocyclic groups, induding the groups Het1, Het2 and Het3, heterocycles representing Ar and R14 and other heterocyclic rings which can be présent in the compounds of the formula I, such as rings formed by two group together with the atom or atoms carrying them, the hetero ring members can be présent in any combination and located in any suitable ring positions, provided that the resulting group and the compound of the formula I are suitable and sufficiently stable as a pharmaceutical active compound. In one embodiment of the invention, two oxygen atoms in any heterocyclic ring in the compounds of the formula I cannot be présent in adjacent ring positions. In another embodiment of the invention, two hetero ring members selected from the sériés consisting of oxygen atoms and sulfur atoms cannot be présent in adjacent ring positions in any heterocyclic ring in the compounds of the formula I. In another embodiment of the invention, two hetero ring members selected from the sériés consisting of nitrogen atoms carrying an exocyclic group like a hydrogen atom or a substituent, sulfur atoms and oxygen atoms cannot be présent in adjacent ring positions in any heterocyclic ring in the compounds of the formula I. In an aromatic heterocyclic ring the choice of hetero ring members is limited by the prerequisite that the ring is aromatic, i.e. it comprises a cyclic system of six delocalized pi électrons. Monocyclic aromatic heterocycles are 5-membered or 6membered rings and, in the case of a 5-membered ring, comprise one ring heteroatom selected from the sériés consisting of oxygen, sulfur and nitrogen, wherein this ring nitrogen carries an exocyclic group like a hydrogen atom or a substituent, and optionally one or more further ring nitrogen atoms, and, in the case of a 6-membered ring, comprise one or more nitrogen atoms as ring heteroatoms, but no oxygen atoms and sulfur atoms as ring heteroatoms. Unless specified otherwise in the définition of the group, heterocyclic groups can be bonded via any suitable ring atom, i.e. any ring atom which carries a hydrogen atom or a substituent, including ring carbon atoms and ring nitrogen atoms. In one embodiment of the invention, any of the heterocyclic groups occurring in the compounds of the formula I in any of its occurrences, is independently of its other occurrences and independently of any other heterocyclic group, bonded via a ring carbon atom, and in another embodiment via a ring nitrogen atom, if applicable. In substituted heterocyclic groups, the substituents can be located in any positions.
The number of ring heteroatoms which can be présent in a heterocyclic group in the compounds of the formula I, the number of cycles, i.e. whether the heterocyclic group can be monocyclic and/or bicyclic, the number of ring members which can be présent, and the degree of saturation, i.e. whether the heterocyclic group is saturated and does not contain a double bond within the ring, or whether it is partially unsaturated and contains one or more, for example one or two, double bonds within the ring but is not aromatic, or whether it is aromatic and thus contains two double bonds within the ring in the case of a 5-membered monocyclic aromatic heterocycle, three double bonds within the ring in the case of a 6-membered monocyclic aromatic heterocycle, four double bonds within the ring in the case of 9-membered bicyclic aromatic heterocycle, and five double bonds within the ring in the case of 10-membered aromatic heterocycle, is specified in the définitions of the individual groups in the compounds of the formula I. The two cycles in a bicyclic heterocyclic group can hâve one, two or more ring atoms in common and can be fused or form a bridged bicycle or a spîrocycle.

An oxo group, i.e. a doubly bonded oxygen atom, when bonded to a carbon atom, replaces two hydrogen atoms on a carbon atom of the parent system. Thus, if a CH2 group is substituted by oxo, it becomes a carbonyl group (C(O), C=O). Oxo groups can also occur on sulfur atoms, such as on ring sulfur atoms in saturated and partially unsaturated heterocycles in which generally, besides a ring sulfur atom, also an S(O) group (S(=O)) and an S(O)2 group (S(=O)2) can be présent as hetero ring members. An oxo group cannot occur as a substituent on a carbon atom in an aromatic ring such as in a phenyl group.

The invention also comprises ail cis/trans isomers of the compounds of the formula I in pure form and essentially pure form, for example with a molar ratio of the cis/trans isomers of 98:2, or 99:1, or greater, and in the form of mixtures of the cis isomer and the trans isomer in ail ratios. Cis/trans isomerism can occur in substituted rings. The préparation of individual stereoisomers, if desired, can be carried out by resolution of a mixture according to customary methods, for example, by chromatography or çrystallization, or by use of stereochemically uniform starting compounds in the synthesis, or by stereoselective reactions. Optionally, before a séparation of stereoisomers a derivatization can be carried out. The séparation of a mixture of stereoisomers can be carried out at the stage of the compound of the formula I or at the stage of an intermediate in the course of the synthesis. For example, in the case of a compound of the formula I containing an asymmetric center the individual enantiomers can be prepared by preparing the racemate of the compound of the formula I and resolving it into the enantiomers by high pressure liquid chromatography on a chiral phase according to standard procedures, or resolving the racemate of any intermediate in the course of its synthesis by such chromatography or by çrystallization of a sait thereof with an optically active amine or acid and converting the enantiomers of the intermediate into the enantiomeric forms of the final compound of the formula I, or by performing an enantioselective reaction in the course of the synthesis. The invention also comprises ail tautomeric forms of the compounds of the formula I.
If the compounds of the formula I comprise one or more acidic or basic groups for example basic heterocyclic groups, the corresponding physiologically or toxicologically acceptable salts are also included in the invention, especially the pharmaceutically acceptable salts. The compounds of the formula I may thus be deprotonated on an acidic group and be used for example as alkali métal salts, for example sodium or potassium salts, or as ammonium salts, for example as salts with ammonia or organic amines or amino acids. Compounds of the formula I comprising at least one basic group may also be prepared and used in the form of their acid addition salts, for example in the form of pharmaceutically acceptable salts with inorganic acids and organic acids, such as salts with hydrochloric acid and thus be présent in the form of the hydrochlorides, for example. Salts can in general be prepared from acidic and basic compounds of the formula I by reaction with an acid or base in a solvent or diluent according to customary procedures. If the compounds of the formula I simultaneously contain an acidic and a basic group in the molécule, the invention also includes internai salts (betaines, zwitterions) in addition to the sait forms mentioned. The présent invention also comprises ail salts of the compounds of the formula I which, because of low physiological tolerability, are not directly suitable for use as a pharmaceutical, but are suitable as intermediates for chemical reactions or for the préparation of physiologically acceptable salts, for example by means of anion exchange or cation exchange.

K
Another subject of the présent invention are processes for the préparation of the compounds of the formula I which are outlined below and by which the compounds of the formula I and intermediates occurring in the course of their synthesis are obtainable. For example, one such process relates to the formation of compounds of theformula I from chroman-6-ols ofthe formula II and 2-chloro-thiazoles ofthe formula lll, and includes the linkage of the thiazole ring to the chroman ring to give compounds of the formula IV, and the subséquent conversion of the group Y into the group R2 that is attached to the thiazole ring in the final compounds of the formula I.
The groups Ar, R3 and R4 in the compounds of the formulae II, lll and IV are defined as in the compounds ofthe formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. The group Y in the compounds of the formulae lll and IV, which group is subsequently transformed into the group R2 in the compound of the formula I, is selected from the sériés consisting of R50-0-C(0)-, H-C(O)- and NC-, wherein R50 is (Ci-C4)-alkyl. The reaction ofthe compounds of the formulae II and lll is generally performed in an inert solvent, in particular an aprotic solvent, for example an ether such as tetrahydrofuran (THF), dioxane or 1,2-dimethoxyethane (DME) or an amide such as dimethylformamide (DMF), dimethylacetamide or Nmethylpyrrolidin-2-one (NMP) in the presence of a base, for example a basic alkali métal sait like an alkali métal carbonate such as sodium carbonate, potassium carbonate or césium carbonate, at températures from about 20°C to about 100°C, in particular from about 40°C to about 60°C. In one embodiment of the invention, R50 is (Ci-C2)-alkyl, for example methyl or ethyl, in another embodiment it is tert-butyl.
Compounds of the formula IV in which the group Y is the group R50-O-C(O)-, which are designated as compounds of the formula IVa, in particular compounds of the formula IVa in which R50 is (Ci-C2)-alkyl, can be reacted with amines ofthe formula V under standard conditions for the aminolysis of esters, for example in a solvent such as a hydrocarbon like toluene, a chlorinated hydrocarbon like dichloromethane, 1,2-dichloroethane or chlorobenzene or an ether like THF, dioxane or DME at températures from about 20°C to about 120 °C, to give compounds of the formula I in which R2 is the group R5-N(R6)-C(O)-, i.e. compounds ofthe formula la.
R5 /
VI
Compounds of the formula IV can also be transformed into compounds of the formula la in a convenient manner by first converting the compound of the formula IVa into the respective carboxylic acid of the formula VI, or a sait thereof, and reacting the compound of the formula VI or its sait with an amine of the formula V under standard conditions for the formation of amides from carboxylic acids. The groups Ar, R3, R4,
R5 and R6 in the compounds of the formulae IVa, V and VI are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group.
Compounds of the formula IVa can be converted into compounds of the formula VI by treatment with an acid or base, for example by treatment with an alkali métal hydroxide such as lithium hydroxide, sodium hydroxide or potassium hydroxide in a solvent such as an ether like THF, dioxane or DME or an alcohol such as methanol or éthanol, or a mixture of solvents, in particular an aqueous solvent or mixture of solvents, or by treatment with hydrochloric acid or trifluoroacetic acid in a solvent such as a chlorinated hydrocarbon like dichloromethane, an ether or an alcohol, in particular in the case of a tert-butyl ester, at températures from about 20°C to about 100°C, followed by standard work-up procedures such as an acidification in case the ester of the formula IVa is hydrolyzed in the presence of a base and a free carboxylic acid of the formula VI is to be prepared, wherein the detailed conditions dépend on the particulars of the spécifie case, as usual, and are readily chosen by a person skilled in the art. For the reaction with the compound of the formula V, the carboxylic acid group HO-C(O)- in the compound of the formula VI is generally activated in situ by means of a customary amide coupling reagent or converted into a reactive carboxylic acid dérivative which can be prepared in situ or isolated. For example, the compound of the formula VI can be converted into an acid halide, e. g. by treatment with thionyl chloride, phosphorus pentachloride or oxalyl chloride, or treated with an alkyl chloroformate like ethyl chloroformate or isobutyl chloroformate to give a mixed anhydride. Customary coupling reagents which can be employed, are propanephosphonic anhydride, Ν,Ν'-carbonyldiazoles like N,N'-carbonyldiimidazole (CDI), carbodiimides like 1,3-diisopropylcarbodiimide (DIC), 1,3dicyclohexylcarbodiimide (DCC) or 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC), carbodiimides together with additives like 1-hydroxybenzotriazole (HOBT) or 1-hydroxy-7-azabenzotriazole (HOAT), uronium-based coupling reagents like O-(7-azabenzotriazol-1-yl)-N,N,N',N‘-tetramethyluronium hexafluorophosphate (HATU), O-(benzotriazol-1 -yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate (HBTU) or O-(cyano(ethoxycarbonyl)methyleneamino)Ν,Ν,Ν',Ν'-tetramethyluronium tetrafluoroborate (TOTU), and phosphonium-based coupling reagents like (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP), (benzotriazol-1 -yloxy)tripyrrolidinophosphonium hexafluorophosphate (PyBOP) or bromotripyrrolidinophosphonium hexafluorophosphate (PyBroP). The reaction of the activated compound of the formula VI or a reactive dérivative of the compound of the formula VI is generally carried out in an inert solvent, for example a hydrocarbon like toluene, a chlorinated hydrocarbon like dichloromethane, an ether like THF, dioxane or DME, an ester like ethyl acetate or butyl acetate, a nitrile like acetonitrile, an amide like DMF or NMP, or water, or a mixture of solvents, at températures from about -10 °C to about 100 °C, in particular at températures from about 0 °C to about 60 °C. Favorably, the reaction is carried out in the presence of a base such as a tertiary amine, like triethylamine, ethyldiisopropylamine, N-methylmorpholine or pyridine, or an inorganic base such as an alkali métal hydroxide, carbonate or hydrogencarbonate, like sodium hydroxide, potassium hydroxide, sodium carbonate or sodium hydrogencarbonate.
Compounds of the formula IV in which the group Y is the group H-C(O)-, i.e. an aldéhyde group or formyl group, which are designated as compounds of the formula IVb, can be reacted with amines of the formula V, in particular amines in which at least one of the groups R5 and R6 is different from hydrogen, in a reductive amination reaction to give compounds of the formula I in which R2 is the group R5N(R6)-CH2-, i.e. compounds of the formula Ib.
The groups Ar, R3 and R4 in the compounds of the formula IVb are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. The reductive amination can be carried out with a complex borohydrtde as reducing agent such as sodium cyanoborohydride or sodium triacetoxyborohydride, which can favorably be used also in polymer-bound form, in a solvent such an ether like THF, dioxane or DME, an alcohol like methanol or éthanol, or an acid like acetic acid, or a mixture of solvents, at températures from about 0°C to about 70°C.
Compounds of the formula IV in which the group Y is the group NC-, i.e. a nitrile group or cyano group, which are designated as compounds of the formula IVc, can be reduced to aminomethyl compounds of the formula It, which can then be acylated with compounds of the formula VII and sulfonylated with compounds of the formula VIII to give further compounds of the formula I in which R2 is the group R7-C(O)-NHCH2- and the group R7-S(O)2-NH-CH2-, respectively, i.e. compounds ofthe formulae le and Id.
The groups Ar, R3, R4 and R7 in the compounds of the formulae It, IVc, VII and VIII are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. The groups X1 and X2 in the compounds of the formulae VII and VIII are nucleophilically substitutable leaving groups, in particular chlorine, in which latter case the compounds of the formulae VII and VIII are carboxylîc acid chlorides and sulfonic acid chlorides. The groups X1 and X2 can also be a hydroxy group, in which case the compounds of the formulae VII and VIII are carboxylic acids and sulfonic acids which are generally activated in situ by means of a customary amide coupling reagent or converted into a reactive carboxylic acid dérivative, such as the compound in which X1 or X2 is chlorine, for the reaction with the compound of the formula It. The explanations on activating agents and reaction conditions given above with respect to the reaction of the compounds of the formula VI with the compounds of the formula V to give carboxamides apply correspondingly to the reaction of the compounds of the formulae VII and VIII with the compounds of the formula It to give carboxamides and sulfonamides. The réduction of the nitrile group in the compounds of the formula IVc to the aminomethyl group in the compounds of the formula It can be performed with various reducing agents known to a person skilled in the art, such as complex métal hydrides or boranes, or by catalytic hydrogénation in the presence of a hydrogénation catalyst, for example Raney nickel, in a solvent such as an ether like THF, dioxane or DME, an alcohol like methanol or éthanol, or water or a mixture of solvents, at températures from about 0°C to about 80°C, the detailed conditions being dépendent on the chosen reducing agent and the particulars of the spécifie case.
Compounds of the formula IV and It can be transformed into further compounds of the formula I also according to other synthetic strategies. For example, in case compounds of the formula Ib are to be prepared in which one of the groups R5 and R6 is hydrogen and the other is a substituted methyl group, such as a group of the type R14-CH2-, a reductive amination reaction with a compound of the formula It and an aldéhyde of the formula R14-C(O)-H can be performed in a manner as described above for the reaction of the compounds of the formulae IVb and V. Compounds of the formulae Ib, le and Id can also be obtained by reducing a compound of the formula IVa or a compound of the formula IVb to the respective compound in which the group Y is a hydroxymethyl group HO-CH2-, converting the hydroxy group into a nucleophilically substitutable leaving group such as chlorine or bromine or a sulfonyloxy group like methanesulfonyloxy, and reacting the obtained alkylating agent with an amine of the formula V, an amide of the formula R7-C(O)-NH2 or a sait thereof, or a sulfonamide of the formula R7-S(O)2-NH2 or a sait thereof, respectively, wherein in the compounds of the formulae R7-C(O)-NH2 and R7-S(O)2-NH2 the groups R7 are defined as in the compounds of the formula I and additionally functional groups can be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. Further, compounds ofthe formulae IVa, IVb, IVc and VI can be converted into one another. If it is more convenient in a spécifie case to react a compound of the formula II with a compound of the formula III in which Y is either RSO-O-C(O)- or H-C(O)- or NC-, the obtained compound of the formula IV or a subsequently obtained compound of the formula VI can be converted by standard procedures into compounds of the formula IV in which Y has another meaning. For example, a carboxylic acid ester of the formula IVa or a nitrile of the formula IVc can be reduced to the aldéhyde of the formula IVb, or a compound of the formula IVa or the formula VI can be converted into the carboxamide and the latter dehydrated to the nitrile of the formula IVc, or an aldéhyde of the formula IVb can be oxidized to a carboxylic acid of the formula VI, or a nitrile of the formula IVc can be hydrolyzed to the carboxylic acid of the formula VI.
For obtaining further compounds of the formula I, various transformations of functional groups can be carried out under standard conditions in compounds of the formula I obtained as described above, or in intermediates or starting compounds in the synthesis of the compounds of the formula I. For example, a hydroxy group can be reacted with a carboxylic acid or a reactive dérivative thereof in a similar manner as described above for the reaction of a carboxylic acid with an amine to give a carboxylic acid ester. Ethérifications of hydroxy groups can be performed by alkylation with the respective halogen compound, for example a bromide or iodide, in the presence of a base such an alkali métal carbonate like potassium carbonate or césium carbonate in an inert solvent such as an amide like DMF or NMP or a ketone like acetone or butan-2-one, or with the respective alcohol under the conditions of the Mitsunobu reaction in the presence of a phosphine like triphenylphosphine or tributylphosphine and an azodicarboxylic acid dérivative like diethyl azodicarboxylate or diisopropyl azodicarboxylate. By reaction with an isocyanate, a hydroxy group can be converted into an N-substituted carbamic acid ester. By treatment with a suitable halogenating agent, a hydroxy group can be converted into a halide. By treatment with sulfur trioxide in the presence of pyridine, a hydroxy group can be converted into the sulfuric acid mono ester. By treatment with a suitable phosphoramidite, such as dibenzyl Ν,Ν-diisopropyl-phosphoramidite, diallyl Ν,Ν-diisopropylphosphoramidite or di-tert-butyl Ν,Ν-diisopropyl-phosphoramidite of the formula (isopropyl)2N-P(O-R55)2, in which R55 is benzyl, allyl or tert-butyl, for example, in the presence of tetrazole and subséquent oxidation, for example with a peracid like 3-chloro-perbenzoic acid, a hydroxy group can be converted into its phosphoric acid ester dibenzyl ester, phosphoric acid ester diallyl ester and phosphoric acid ester di-tert-butyl ester, respectîvely, which can be cleaved to the phosphoric acid mono ester of the hydroxy group, i.e. the compound which contains the group (HO)2P(O)- attached to the oxygen atom of the hydroxy group, by catalytic hydrogénation in the presence of a palladium catalyst in the case of the dibenzyl ester, by a palladium-catalyzed nucleophilic substitution in the case of the diallyl ester, and by treatment with an acid such as trifluoroacetic acid in the case of the di-tert-butyl ester. By treatment with chloromethyl chloroformate and subsequently with silver dibenzylphosphate, a hydroxy group can be converted into the carbonic acid ester dibenzyloxyphosphoryloxymethyl ester, which can be cleaved to the carbonic acid ester phosphonooxymethyl ester of the hydroxy group. i.e. the compound which contains the group (HO)2P(O)-O-CH2-O-C(O)-attached to the oxygen atom ofthe hydroxy group, by catalytic hydrogénation in the presence of a palladium catalyst (cf. WO 2010/039474). A halogen atom can be replaced with a variety of groups in a substitution reaction which may also be a transition-métal catalyzed reaction. An amino group can be modified under standard conditions for alkylation, for example by reaction with a halogen compound or by reductive amination of a carbonyl compound, or for acylation or sulfonylation, for example by reaction with an activated carboxylic acid or a carboxylic acid dérivative like an acid chloride or anhydride. A carboxylic acid ester group can be hydrolyzed under acidic or basic conditions to give a carboxylic acid. A carboxylic acid group can be activated or converted into a reactive dérivative as outlined above and reacted with an alcohol or an amine or ammonia to give an ester or amide. A primary amide can be dehydrated to give a nitrile. A sulfur atom in an alkyl-S- group or in a heterocyclic ring can be oxidized with a peroxide like hydrogen peroxide or a peracid to give a sulfoxide moiety (S(O)) or a sulfone moiety (S(O)2). A carboxylic acid group, carboxylic acid ester group and a ketone group can be reduced to an alcohol, for example with a complex hydride such al lithium aluminium hydride, lithium borohydride or sodium borohydride, A hydroxy group can be oxidized to an oxo group by means of pyridinium chlorochromate or the DessMartin periodinane reagent, for example. Ail such reactions in the préparation ofthe compounds of the formula I are known per se and can be carried out in a manner familiar to a person skilled in the art according to, or analogously, to procedures which are described in the standard literature, for example in Houben-Weyl, Methods of Organic Chemistry, Thieme; or Organic Reactions, John Wiley & Sons; or R. C. Larock, Comprehensive Organic Transformations: A Guide to Functional Group Préparations, 2. ed. (1999), John Wiley & Sons, and the references quoted therein.
The chroman-6-ols of the formula II which are employed in the synthesis of the compounds of the formula IV described above, can be obtained by different processes. In one of them, an acetophenone of the formula IX, which is substituted in the benzene ring by a hydroxy group and a group G1 and can additionally be substituted in the benzene ring and the acetyl group by substituents R4, is condensed with an aldéhyde of the formula X in the presence of a base to give a chroman-4-one of the formula XII and/or a chalcone of the formula XI, and an obtained chalcone of the formula XI subsequently cyclized to the chroman-4-one of the formula XII.
The groups Ar and R4 in the compounds of the formulae IX, X, XI and XII are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. The group G1 in the compounds of the formulae IX, XI and XII is a hydroxy group or bromine. When performing the reaction of the compounds of the formulae IX and X in the presence of an alkali métal hydroxide such as potassium hydroxide as the base in a solvent such as an alcohol like methanol or éthanol at températures from about 30°C to about 70°C, the obtained product is the chalcone of the formula XI. When performing the reaction of the compounds of the formulae IX and X in the presence of a sait of a weak acid such as ammonium acetate, for example, in a solvent such as acetic acid at températures from about 100°C to about 120°C, the obtained product is a mixture ofthe chalcone of the formula XI and chroman-4-one of the formula XII. The compound of the formula XI, as well as a mixture of the compounds of the formulae XI and XII, can be employed in the cyclization reaction to give the compound of the formula XII, which can be carried out by treating the starting material with an acid like hydrochloric acid or with an amine like ethyldiisopropylamine and potassium fluoride, in a solvent such as an alcohol like methanol or éthanol at températures from about 60°C to about 100°C.
U
The oxo group in the ring position 4 of the compounds of the formula XII is then reduced to a CH2 group to give the compounds of the formula XIV, favorably stepwise via the 4-hydroxy-chroman dérivatives ofthe formula XIII.
The groups Ar and R4 in the compounds ofthe formulae XIII and XIV are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. The group G1 in the compounds of the formulae XIII and XIV is a hydroxy group or bromine. The réduction of the compounds ofthe formula XII to the compounds of the formula XIII can be carried out under standard conditions for the réduction of a ketone to an alcohol, for example by means of a complex hydride as reducing agent, or a borane dérivative, such as the borane-tetrahydrofuran complex in a solvent such as an ether like THF or dioxane, at températures from about 30°C to about 80°C. The réduction of the compounds ofthe formula XIII to the compounds of the formula XIV can be performed, for example, by treatment with a silane reducing such as a trialkylsilane like triethylsilane and an acid such as trifluoroacetic acid in a solvent such as a chlorinated hydrocarbon like dichloromethane at températures from about 0°C to about 40°C. In case the group G1 in the compound of the formula XIII and its precursor compounds is a hydroxy group, the obtained compound of the formula XIV already is a compound of the formula II. In case the group G1 in the obtained compound of the formula XIV is bromine, it can be converted into a hydroxy group by metalation of the compound of the formula XIV with a organolithium compound such as butyllithium and treatment with a trialkyl borate such as triisopropyl borate in a solvent such as a hydrocarbon like heptane or cyclohexane or an ether like THF or dioxane at températures from about -80°C to bL about 0°C, followed by oxidative cleavage, for example by means of hydrogen peroxide in the presence of a base such as sodium hydroxide.
Further processes for the préparation of chroman-6-ols of the formula II involve a cyclization of 3-hydroxypropyl-substituted benzene dérivative of the formula XV, which is substituted in the benzene ring by two suitable groups G2 and G3 and can additionally be substituted in the benzene ring and the propyl group by substituents R4, to give a chroman dérivative of the formula XVI, in which the group G3 is then converted into the hydroxy group présent in the compounds of the formula II.
XV
The groups Ar and R4 in the compounds of the formulae XV and XVI are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. The group G2 in the compounds of the formula XV can be a hydroxy group or a nucleophilically substitutable leaving group, for example fluorine. The group G3 in the compounds of the formulae XV and XVI can be bromine or (CiC4)-alkyl-O- such as methoxy, for example. In case G3 is bromine, the conversion of the group G3 in the compound of the formula XVI into the hydroxy group in the compound of the formula II can be performed as described above for the conversion of the compounds of the formula XIV into the compounds of the formula II. In case G3 is (Ci-C4)-alkyl-O-, the conversion into the hydroxy group can be performed according to standard procedures for ether cleavage, for example by treatment with boron tribromide in a chlorinated hydrocarbon such as dichloromethane at températures from about -20°C to about 10°C in the case of a methoxy group, In case the group G2 is a hydroxy group, the cyclization of the compound of the formula
XV to the compound of the formula XVI can conveniently be performed under the conditions of Mitsunobu reaction by treatment with a phosphine such as triphenylphosphine or tributylphosphine and an azodicarboxylic acid dérivative such as diethyl azodicarboxylate or diisopropyl azodicarboxylate in a solvent such as an ether like THF or dioxane at températures from about 0° to about 30°C. In case the benzene ring carrying G2 in the compound of the formula XV is susceptible to a nucleophilic aromatic substitution and G2 is a leaving group such as fluorine, the cyclization can be performed by treatment of the compound of the formula XV with a base which enhances the nucleophilicity of the hydroxy group in position 3 of the propyl group, for example an alkali métal amide or an alkali métal hydride like sodium hydride, in an inert solvent such as an ether like THF or dioxane or an amide like DMF or NMP at températures from about -20°C to about 100°C.
By cyclization of compounds of the formula XV also individual stereoisomeric forms of the compounds of the formula XVI and II, and finally of compounds of the formula I, can be conveniently be prepared in which the chiral carbon atom in position 2 of the chroman ring System is présent either in R configuration or in S configuration. For the synthesis of such individual stereoisomers, which can otherwise be obtained, for example, by chromatographie resolution on a chiral phase of a mixture of the stereoisomers of the final compounds of the formula I or at any stage of the synthesis, the individual stereoisomeric forms of the 3-hydroxypropyl-substituted benzene of the formula XV are employed, i.e. the compounds of the formula XVa. Depending on the cyclization reaction and the conditions chosen, the cyclization can proceed with rétention or inversion of the configuration of the chiral carbon atom to give the individual stereoisomeric forms of the compounds of the formula XVI, i.e. the compounds of the formula XVIa, which can be reacted further to the individual stereoisomeric forms compounds of the formulae II and I. In the compounds of the formulae XVa and XVIa are the groups Ar, R4, G2 and G3 defined as in the compounds of the formula XV and XVI, respectively, and the depicted chiral carbon atom is présent, or is essentially présent, either in R configuration or in S configuration, as is indicated by the wavy wedge.
One embodiment of the présent invention thus relates to a process for the préparation of a compound of the formula I,
which comprises cyclizing a compound of the formula XV to a compound of the formula XVI, converting the compound of the formula XVI into a compound of the formula II, reacting the compound of the formula II with a compound of the formula III to give a compound of the formula IV, and converting the compound of the formula IV into a compound of the formula I, wherein the groups Ar, R3 and R4 in the compounds of the formulae II, III, IV, XV and XVI are defined as in the compounds of the formula I, and additionally can functionai groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group, the group G2 in the compound of the formula XV is a hydroxy group or a nucleophilically substitutable leaving group, for example fluorine, the group G3 in the compounds of the formulae XV and XVI is bromine or (Ci-C4)-alkyl-O-, and the group Y in the compounds of the formulae III and IV is R50-O-C(O)-, H-C(O)- or NC-, wherein R50 is (Ci-C+J-alkyl.
Another embodiment of the présent invention relates to the process described afore, in which the chiral carbon atom carrying the group Ar in the compounds of the formulae II, IV, XV and XVI is présent, or is essentially présent, in uniform configuration, either in R configuration or in S configuration, i.e. to a process for the préparation of a compound of the formula Iq,
which comprises cyclizing a compound of the formula XVa to a compound of the formula XVIa, converting the compound of the formula XVIVa into a compound of the formula lia, reacting the compound of the formula lia with a compound oftheformula
III to give a compound of the formula IVd, and converting the compound of the formula IVd into a compound ofthe formula Iq, wherein the groups Ar, R2, R3 and
R4 in the compounds of the formulae Iq, lia, III, IVd, XVa and XVIa are defined as in the compounds ofthe formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group, the group G2 in the compound of the formula XVa is a hydroxy group or a nucleophilically substitutable leaving group, for example fluorine, the group G3 in the compounds of the formulae XVa and XVIa is bromine or (C1-C4)alkyl-O-, and the group Y in the compounds of the formulae III and IVd is R50-OC(O)-, H-C(O)- or NC-, wherein R50 is (Ci-C4)-alkyl, wherein the chiral carbon atom carrying the group Ar in the compounds of the formulae Iq, lia, IVd, XVa and XVIa is présent, or is essentially présent, in uniform configuration, either in R configuration or in S configuration.
The compounds of the formula XV, including the stereoisomeric forms of the formula XVa, which are employed in the cyclization reaction to the compounds of the formulae XVI and XVIa described above, can be obtained according to, or analogously to, various processes which are described in the literature. For example, a 3-oxo-propionic acid ester of the formula XVII can be alkylated with a benzyl halide of the formula XVIII to give a 3-oxo-propyl-substituted benzene derivative ofthe formula XIX, in which the ketone group is then reduced to the alcohol group to give a compound of the formula XV.
The groups Ar and R4 in the compounds of the formulae XVII, XVIII and XIX are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. In the préparation of compounds of the formula XV according to this process, the group G2 in the compounds of the formulae XVIII and XIX is in particular a nucleophilically substitutable leaving group, for example fluorine, and the group G3 in the compounds of the formulae XVIII and XIX in particular is bromine. The group R51 in the compounds ofthe formula XVII is (Ci-C4)-alkyl, for example methyl or ethyl. The group X3 in the compounds of the formula XVIII is a nucleophilically substitutable leaving group, for example chlorine or bromine. The reaction ofthe compounds ofthe formulae XVII and XVIII to give the compounds of the formula XIX is performed in an inert solvent such as an ether like THF, dioxane or DME in the presence of base such as an alkali métal alkoxide or an alkali métal hydride, for example sodium hydride, at températures from about 0°C to about 50°C. By treatment of the obtained benzylated 3-oxO'propionic acid ester with an acid, for example hydrochloric acid in an aqueous solvent such as an ether like dioxane or an acid like acetic acid or a mixture of solvents at températures from about 60°C to about 120°C the ester moiety is then saponified and decarboxylated to give the ketone ofthe formula XIX. For the réduction of the ketone moiety in the compounds of the formula XIX to the compounds of the formula XV, various reducing agents can be employed, for example complex métal hydride such as sodium borohydride or lithium borohydride in a solvent such as an ether or an alcohol. In an asymmetric réduction reaction, by employing a chiral reducing agent, for example an enantiomeric form of a chiral complex métal hydride or a chiral borane, such as an alpha-pinene-based organoborane like B-chloro-diisopinocampheylborane, which is commonly abbreviated as (-)-lpc2BCI or (-)-DipCI, and (+)-lpc2BCI or (+)-DipCI, respectively, in an inert solvent such as an ether like THF or dioxane at températures from about -40°C to about 30°C, conveniently the individual stereoisomeric forms of the compounds of the formula XV can be obtained, i.e. compounds of the formula XVa, which can be cyclized to the enantiomeric forms of the compounds of the formula XVI, i.e. the compounds of the formula XVIa, as described above,
In another process for the préparation of compounds of the formula XV, an indan-1one of the formula XX is subjected to a ring enlargement to give a chroman-2-one of the formula XXI, in which the lactone moiety can be reduced to an aldéhyde moiety which is présent in the form of the cyclic hemiacetal of the formula XXII and which can be reacted with a suitable organometal compound of the formula XXIII.
XXI
XXII
The groups Ar and R4 in the compounds of the formulae XX, XXI, XXII and XXIII are defined as in the compounds of the formula I, and additionally can functional groups be présent in protected form or in the form of a precursor group which is subsequently converted into the final group. In the préparation of compounds of the formula XV according to this process, the group G3 in the compounds of the formulae XX, XXI and XXII is in particular a (Ci-C4)-alkyl-O- group. The group M in the compounds of the formula XXIII is a métal or a métal équivalent, for example lithium. The conversion of the compound of the formula XX into the compound of the formula XXI can be performed by treatment with a peracid such as 3-chloroperbenzoic acid in a solvent such as a chlorinated hydrocarbon like dichloromethane at températures from about -10°C to about 30°C. For the réduction of the lactone moiety in the compound of the formula XXI to the masked aldéhyde moiety in the compound of the formula XXII, a complex métal reducing agent can be used, such as diisobutylaluminum hydride, in a solvent such as a hydrocarbon like cyclohexane or toluene or a chlorinated hydrocarbon like dichloromethane or an ether like THF or dioxane, or a mixture of solvents, at températures from about -80°C to about 30°C. For the subséquent step, the compound of the formula XXIII is generally prepared in situ from a suitable respective benzene or aromatic heterocycle or halogensubstituted benzene or halogen-substituted aromatic heterocycle by metalation, for
À example with an organolithium compound like butyllithium or a lithium amide like lithium diisopropylamide or lithium 2,2,6,6-tetramethylpiperidide, and reacted with the compound of the formula XXII in an inert solvent such as a hydrocarbon like heptane or cyclohexane or an ether like THF or a mixture of solvents at températures from about -80°C to about 30°C.
As already indicated, it can be advantageous or necessary in ail reactions which are carried out in the course of the préparation of the compounds of the formula I to temporarily protect functional groups or have them initially présent in the form of precursor groups, and later deprotect them or convert them into the desired groups. Appropriate synthesis strategies and protective groups and precursor groups which are suitable for the respective case, are known to the person skilled in the art and can be found in P. G. M. Wuts and T. W. Greene, Greene's Protective Groups in Organic Synthesis, 4. ed. (2007), John Wiley & Sons, for example. Examples of protective groups which may be mentioned, are benzyl protective groups, for example benzyl ethers of hydroxy compounds and benzyl esters of carboxylic acids, from which the benzyl group can be removed by catalytic hydrogénation in the presence of a palladium catalyst, tert-butyl protective groups, for example tert-butyl esters of carboxylic acids, from which the tert-butyl group can be removed by treatment with trifluoroacetic acid, acyl protective groups, for example ester and amides of hydroxy compounds and amino compounds, which can be cleaved again by acidic or basic hydrolysis, or alkoxycarbonyl protective groups, for example tertbutoxycarbonyl dérivatives of amino compounds, which can be cleaved again by treatment with trifluoroacetic acid. Examples of precursors which may be mentioned are halogen atoms which can be replaced by many other groups, or nitro groups which can be converted, for example by catalytic hydrogénation, into amino groups which can be diazotized and converted into a large number of groups.
The starting materials employed in the procedures outlined above are commercially available or can be prepared according to procedures, or in analogy to procedures, described in the literature. Procedures for the préparation of 2-chloro-thiazole dérivatives of the formula III, for example, are described in US 4168380, WO <·
01/17995 or I. Sawhney et al., J. Chem. Soc. Perkin Trans. 1 (1990), 329-331, for example.
As is usual and applies to all reactions performed in the course of the synthesis of a compound of the formula I, appropriate details of the conditions applied in a spécifie préparation process, including the solvent, a base or acid, the température, the order of addition, the molar ratios and other parameters, are routinely chosen by the skilled person in view of the characteristics of the starting compounds and the target compound and the other particularities of the spécifie case. As is also known by the skilled person, not all processes described herein will in the same way be suitable for the préparation of all compounds of the formula I and their intermediates, and adaptations hâve to be made. In all processes for the préparation of the compounds of the formula I, workup of the reaction mixture and the purification of the product is performed according to customary methods known to the skilled person which include, for example, quenching of a reaction mixture with water, adjustment of a certain pH, précipitation, extraction, drying, concentration, crystallization, distillation and chromatography. Also for the characterization of the product, customary methods are used such as NMR, IR and mass spectroscopy.
Another subject of the présent invention are the novel starting compounds and intermediates occurring in the synthesis of the compounds of the formula I, including the compounds ofthe formulae II, lll, IV, IVa, IVb, IVc, IVd, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVa, XVI, XVIa, XVII, XVIII, XIX, XX, XXI, XXII and XXIII, wherein the groups Ar, R2, R3. R4, R5, R6, R7, R50, R51, G1, G2, G3, Μ, X1, X2, X3 and Y are defined as above, in any of their stereoisomeric forms or a mixture of stereoisomeric forms in any ratio, and their salts, and their use as synthetic intermediates or starting compounds. All general explanations, spécifications of embodiments and définitions of numbers and groups given above with respect to the compounds of the formula I apply correspondingly to the said intermediates and starting compounds. A subject of the invention are in particular the novel spécifie starting compounds and intermediates described herein. Independently thereof whether they are described as a free compound and/or as a spécifie sait, they are a subject of the invention both in the form of the free compounds and in the form of their salts, and if a spécifie sait is described, additionally in the form of this spécifie sait.
The compounds of the formula I inhibit the sodium-calcium exchanger (NCX), especially the sodium-calcium exchanger of subtype 1 (NCX1), as can be demonstrated in the pharmacological tests described below and in other pharmacological tests which are known to a person skilled in the art, for example in animal models in which the effect on heart function can be determined ex vivo or in vivo. The compounds of the formula I and their pharmaceutically acceptable salts therefore are valuable pharmaceutical active compounds. The compounds of the formula I and their pharmaceutically active salts can be used for the treatment of heart failure, including acute and chronic congestive heart failure, systolic heart failure, diastolic heart failure, heart failure with preserved éjection fraction and diabetic heart failure, cardiac arrhythmias including atrial fibrillation, stroke, dementia including Alzheimer's Disease, hypertension, cardiac ischemia, rénal failure, shock including hémodynamie shock, cardiogenic shock and septic shock, age-related disorders, and diseases which are caused secondarily by an NCX-related damage, for example. The treatment of diseases is to be understood as meaning both the therapy of existing pathological changes or malfunctions of the organism or of existing symptoms with the aim of relief, alleviation or cure, and the prophylaxis or prévention of pathological changes or malfunctions of the organism or of symptoms in humans or animais which are susceptible thereto and are in need of such a prophylaxis or prévention, with the aim of a prévention or suppression of their occurrence or of an atténuation in the case of their occurrence. For example, in patients who on account of their disease history are susceptible to cardiac arrhythmias, by means of the prophylactic or préventive médicinal treatment the occurrence or re-occurrence of arrhythmias can be prevented or their extent and sequelae decreased. The treatment of diseases can occur both in acute cases and in chronic cases. The compounds of the formula I and their pharmaceutically acceptable salts can further be used in various disorders in order to achieve an improvement of the perfusion of heart, brain and kidney, and in general in disorders □
in which intracellular calcium homeostasis is disturbed, or the NCX is activated in an undesired manner, or an inhibition of the NCX is intended by the physician for improving the patient's condition, where the compounds of the formula I and their pharmaceutically acceptable salts can also be employed in cases where only a certain partial inhibition of the NCX is intended, for example by use of a low dosage.
The compounds of the formula I and their pharmaceutically acceptable salts can therefore be used in animais, in particular in mammals and specifically in humans, as a pharmaceutical or médicament on their own, in mixtures with one another, or in the form of pharmaceutical compositions. A subject of the présent invention also are the compounds of the formula I and their pharmaceutically acceptable salts for use as a pharmaceutical.

A subject of the présent invention also are the use of the compounds of the formula I and their pharmaceutically acceptable salts for the manufacture of a médicament for the treatment of the diseases mentioned above or below, induding the treatment of any one of the mentioned diseases, for example heart failure, cardiac arrhythmias, stroke, dementia, hypertension, cardiac ischemia, rénal failure, shock, age-related disorders or diseases which are caused secondarily by an NCX-related damages, wherein treatment of diseases comprises their therapy and prophylaxie as mentioned above, or a médicament for inhibition of the NCX. A subject of the présent invention also are methods for the treatment of the diseases mentioned above or below, including the treatment of any one of the mentioned diseases, for example heart failure, cardiac arrhythmias, stroke, dementia, hypertension, cardiac ischemia, rénal failure, shock, age-related disorders or diseases which are caused secondarily by an NCX-related damage, wherein treatment of diseases comprises their therapy and prophylaxis as mentioned above, and a method for inhibiting the NCX, which comprise administering an efficacious amount of at Ieast one compound of the formula I and/or a pharmaceutically acceptable sait thereof to a human or an animal which is in need thereof. The compounds of the formula I and their pharmaceutically acceptable salts, and pharmaceutical compositions and médicaments comprising them, can be administered enterally, for example by oral or rectal administration, parenterally, for example by intravenous, intramuscular or subcutaneous injection or infusion, or by another type of administration such as topical, percutaneous, transcutaneous, nasal, pharyngeal or inhalative administration, the preferred form of administration depending on the particulars of the spécifie case. The compounds of the formula I and their pharmaceutically acceptable salts can also be used in combination with other pharmaceutical active compounds.
The pharmaceutical compositions and médicaments according to the invention normally contain from about 0.5 to about 90 percent by weight of a compound or compounds of the formula I or pharmaceutically acceptable salts thereof, and an amount of active ingrédient of the formula I and/or its pharmaceutically acceptable sait which in general is from about 0.1 mg to about 1 g, in particular from about 0.2 mg to about 500 mg, for example from about 1 mg to about 300 mg, per dose unit. Depending on the kind of the pharmaceutical composition and other particulars of the spécifie case, the amount may deviate from the indicated ones. The production of the pharmaceutical compositions and médicaments can be carried out in a manner known per se and familiar to the person skilled in the art. For this, the compounds of the formula I and/or their pharmaceutically acceptable salts are mixed together with one or more solid or liquid vehicles and/or excipients, if desired also in combination with one or more other pharmaceutical active compounds, and brought into a suitable form for dosage and administration, which can then be used in human medicine or veterinary medicine.
As vehicles, which may also be looked upon as diluents or solvents or bulking agents, and excipients suitable organic and inorganic substances can be used which do not react in an undesired manner with the compounds ofthe formula I. As examples of types of excipients, or additives, which can be contained in the pharmaceutical compositions and médicaments, lubricants, preservatives, gel formers, thickeners, stabilizers, disintegrants, wetting agents, emulsifiers, dispersants, antifoaming agents, salts, buffer substances, colorants, flavorings and antioxidants may be mentioned. Examples of vehicles and excipients are water, physiological saline, vegetable oils such as sunflower oil, animal oils such as fish liver oil, waxes, alcohols such as éthanol, isopropanoi, 1,2-propanediol, glycerol, polyols, polyethylene glycols, polyvinylpyrrolidone, gelatin, gum arable, cellulose, carbohydrates such as glucose, lactose or starch like corn starch, magnésium carbonate, potassium phosphate, sodium chloride, stearic acid and its salts such as magnésium stéarate, talc, lanolin, petroleum jelly, or mixtures thereof, for example mixtures of water or saline with one or more organic solvents such as mixtures of water with alcohols.
For oral and rectal use, pharmaceutical forms such as, for example, tablets, coated tablets, sugar-coated tablets, granules, hard and soft gelatin capsules, suppositories, solutions, including oily, alcoholic or aqueous solutions, or drops, furthermore suspensions or émulsions, can be used. For parentéral use, for example by injection or infusion, pharmaceutical forms such as solutions, for example aqueous solutions, can be used. For topical use, pharmaceutical forms such as ointments, creams, pastes, lotions, gels, sprays, foams, aérosols, solutions or powders can be used. Pharmaceutical formulations such as, for example, aérosols and sprays may comprise solutions, suspensions or émulsions of the active ingrédient in a pharmaceutically acceptable solvent, such as éthanol or water, or a mixture of such solvents. The formulation may also comprise other pharmaceutical excipients such as surfactants, emulsifiers and stabilizers, and a propellant gas. Such a
Ή pharmaceutical form normally comprises the active ingrédient in a concentration of about 0.1 to about 10%, in particular of about 0.3 to about 3% by weight.
As usual, the dosage of the compounds of the formula I and the frequency of administration dépend on the circumstances of the spécifie case and is adjusted by the physician according to the customary rules and procedures. It dépends, for example, on the compound of the formula I administered and its potency and duration of action, on the nature and severity of the individual syndrome, on the gender, âge, weight and the individual responsiveness of the human or animal to be treated, on whether the treatment is acute or chronic or prophylactic, or on whether further pharmaceutical active compounds are administered in addition to a compound of the formula I. Normally, in the case of administration to an adult weighing about 75 kg, a dose from about 0.1 mg to about 100 mg per kg per day, in particular from about 1 mg to about 10 mg per kg per day (in each case in mg per kg of body weight), is sufficient. The daily dose can be administered in the form of a single dose or divided into a number of individual doses, for example two, three or four individual doses. The administration can also be carried out continuously, for example by continuous injection or infusion. Depending on the individual behavior in a spécifie case, it may be necessary to deviate upward or downward from the indicated dosages.
Besides as a pharmaceutical active compound in human medicine and veterinary medicine, the compounds of the formula I can also be employed as an aid in biochemical investigations or as a scientific tool or for diagnostic purposes, for example in in vitro diagnoses of biological samples, if an inhibition of the NCX is intended. The compounds of the formula I and their salts can also be used as intermediates for the préparation of further pharmaceutical active substances.

Pharmacological examples
A) Assay method for determining the NCX1 inhibitory activity
The sodium/calcium exchanger NCX1 can transport calcium ions and sodium ions through the cell membrane. The transport is an exchange of Ca2+ and Na* in two directions depending on membrane potential and ion gradients. At the first direction, named “forward mode or calcium export mode”, Ca2* is transported out of the cell and Na* is transported into the cell. At the other direction, named reverse mode” or “calcium import mode, the transport directions are vice versa. The effect ofthe compounds ofthe invention on NCX1 was determined in CHO cells stably expressing human NCX1 (gene symbol SLC8A1; cf. WO 2009/115238). The assay is based on the monitoring of intracellular Ca2* concentrations using a calcium-sensitive fluorescence dye which is detected by means of a FLIPR device (Fluorimetric Imaging Plate Reader, Molecular Devices).
Assay technology - reverse mode
The assay is based on the monitoring of intracellular Ca2* concentrations using the calcium-sensitive dye Fluo-4. CHO cells expressing NCX1 were loaded with the dye by means of the acetoxymethyl ester Fluo4 AM (Invitrogen, F14202), which is cleaved intracellularly by esterase activity to yield the charged species of free Fluo-4.
After an preincubation period with the test compound, Gramicidine (Sigma, G5002) was added. Gramicidine is an ionophorfor Na* ions mediating an increase of intracellular Na* ions. Consequently, intracellular Na* ions are exchanged against
154 extracellular Ca2+ ions (Ca2+ influx, reverse mode). The intracellular élévation of Ca2+ ions was detected by measuring the fluorescence of Fluo-4 at a wavelength of 520 nm by a FLIPR device.
Briefly, for the reverse mode transport assay 18000 cells per well were seeded into a 96 well microplate (Corning COSTAR 3904) and incubated ovemight in culture medium (1X Nut Mix F12 (Ham) (Gibco, 21765-029); 10% (v/v) fêtai calf sérum (PAA Gold, A15-649); 450 pg/ml Geneticin (Gibco, 10131-027)). A total volume of 100 μΙ medium per well was used. For the préparation of the FLIPR assay, the culture medium was removed from the plates and 100 μΙ of dye solution (2 μΜ Fluo-4 AM; 0.02% (v/v) Pluronic F-127 (20%, Invitrogen, P3000MP); 0.1% (v/v) bovine albumin solution (30% (v/v), Sigma, A9205) in assay buffer (133.8 mM NaCI (Sigma, S5886);
4.7 mM KCI (Sigma, P3911); 1.25 mM MgCI2 (Merck, 1.05833.0250); 3.5 mM CaCI2 (Merck, 1.02083.0250); 5 mM glucose (Sigma, G7021); 10 mM Hepes (Sigma, H4034); 0.01% (v/v) Pluronic F-127 (5%, Sigma, P2443); 2.5 mM Probenecid (Maybridge, SB00915EB); pH 7.4)) were added into each well. The plates were incubated in the dark at room température for 80 min. After the incubation period, the dye solution was removed and the wells were washed with 100 μΙ of assay buffer. Then 80 μΙ of a solution of the test compound in assay buffer in different concentrations were added into the wells. The plates were incubated at 16°C for 45 min. Meanwhile a 60 μΜ solution of Gramicidine in assay buffer (4°C) was prepared and stored in the wells of a 96 well microplate (96 well microplate, polypropylene, Ushape (Greiner Bio-One, 650201 )) at 4°C until measurement was started. The fluorescence monitoring was performed at 240 measuring points with measurement intervals of 2 sec. After the fifth measuring point, 40 μΙ of the Gramicidine solution were added to each well of the assay plates to give a final Gramicidine concentration of 20 μΜ. For the détermination of the ICso values the minimal fluorescence value was subtracted from the maximal fluorescence value for ail measuring points, The calculation of the ICso values via the percentage inhibitions of Ca2+ influx into cells (reverse mode) effected by the test compound was performed in Biost@t Speed 2.0. Results obtained with compounds of the invention are given in Table 1.

Assay technology - forward mode
The assay is based on the monitoring of intracellular Ca2+ concentrations using the PBX Calcium Assay Kit from BD (Becton, Dickinson and Company) with calcium indicator dye 51-9000177BKa (BD, 640177). CHO cells expressing NCX1 were loaded with the dye, and after a preincubation period with the test compound, lonomycin (Calbiochem, 407950) was added. lonomycin is an ionophorfor Ca2+ ions mediating an increase of intracellular Ca2+ ions. Consequently, intracellular Ca2+ ions are exchanged against extracellular Na+ ions (Ca2+ efflux, forward mode). The decrease of intracellular Ca2+ ions was detected by measuring the fluorescence of the calcium indicator dye at a wavelength of 520 nm by a FLIPR device.
Briefly, similarly as for the reverse mode, for the forward mode transport assay 18000 cells per well were seeded into a 96 well microplate (Corning COSTAR 3904) and incubated overnight in culture medium (cf. above). A total volume of 100 pl medium per well was used. For the préparation of the FLIPR assay, the culture medium was removed from the plates and 100 μΙ of assay buffer (133.8 mM NaCI (Sigma, S5886);
4.7 mM KCI (Sigma, P3911); 1.25 mM MgCI2 (Merck, 1.05833.0250); 3.5 mM CaCI2 (Merck, 1.02083.0250); 5 mM glucose (Sigma, G7021); 10 mM Hepes (Sigma, H4034); pH 7.4)) were added to each well in a washing step. Assay buffer was removed, and 100 μΙ of a solution of the test compound in assay buffer in different concentrations were added into the wells, Further, 100 μΙ of dye solution (0.09% (v/v) calcium indicator dye, 9.1% (v/v) signal enhancer (from PBX Calcium Assay Kit); in assay buffer) were added into each well. The plates were incubated in the dark at room température for 60 min. Meanwhile a 10 μΜ solution of lonomycin in assay buffer (additionally containing 0.05% fêtai calf sérum (cf. above); 4°C) was prepared and stored in the wells of a 96 well microplate (96 well microplate, polypropylene, Ushape (Greiner Bio-One, 650201 )). The fluorescence monitoring was performed at 60 measuring points with measurement intervals of 2 sec. After the fifth measuring point, 50 μΙ of the lonomycin solution were added to each well of the assay plate to give a final lonomycin concentration of 2 μΜ. For the détermination of the ICso values the minimal fluorescence value was subtracted from the maximal fluorescence value for the fifteenth to fifty-fifth measuring points. The calculation ofthe ICso values via the « L
156 percentage inhibitions of Ca2+ efflux out of cells (forward mode) effected by the test compound was performed in Biost@t Speed 2.0. Results obtained with compounds of the invention are given in Table 2. NCXIfw ICso in Table 2 means the IC50 value for inhibition of NCX1 in forward mode (in μΜ (micromol/liter)).

B) In vivo method for determining the effect on heart contractility
Adult male Sprague-Dawley rats (Harlan Winkelmann, Borchen, Germany) weighing 340 to 370 g were anesthetized with pentobarbital (100 mg/kg i.p.) and ventilated with a mixture of oxygen (40%) and room air (60%) at a tidal volume of 1 ml/100 g at 60 breaths/min. Body température was maintained at 36.5 ± 0.3 °C with a heating lamp and was monitored with a rectal thermo sensor. Systemic blood pressure was measured in the left carotid artery using a pressure transducer (Combitrans; B. Braun Melsungen AG, Melsungen, Germany) connected to a DC-bridge-amplifier (PLUGSYS/ADC Type 663; Harvard Apparatus GmbH, March-Hugstetten, Germany). The electrocardiogram was measured as lead II via subcutaneousiy placed électrodes connected to a Heart-Rate-Module (PLUGSYS/HRM Type 669; Harvard Apparatus GmbH, March-Hugstetten, Germany). A micro-tip cathéter (2 French, SPR-320; Millar Instruments, Houston, TX, USA) was placed via the right carotid artery into the left ventricle, and the left ventricular pressure (LVP) and the enddiastolic pressure (EDP) were continuously measured. Registration of the hémodynamie data was performed via an analog digital converter by a personal computer using Notocord software (HEM version 3.5). Left ventricular contractility (dp/dtmax) and relaxation (dp/dtmin) were calculated from the LVP signal. For intravenous administration of the test compounds, the left jugular vein was prepared and a PP-50 cathéter was inserted. Test compounds were administered either by intravenous bolus injection or by intravenous infusion by means of an infusion pump
158 (Unita; B. Braun Melsungen AG, Melsungen, Germany). Test compounds were dissolved in a mixture of Glycofurol (75%) and Cremophor (25%), and the solution was further diluted with distilled water (1:4). In a typical experiment, several dosages of the test compound were administered subsequently at increasing doses. Statistical 5 significance of the data obtained with drug vs control experiments, in which solvent was administered, was evaluated with the 2-sided ANOVA test (program Everstat). Increases in left ventricular contractility (percent increase) by example compounds are given in Table 3 in comparison to control experiments in which solvent was administered.
