Carboxylic acid derivatives, their preparation and their use

The present invention relates to novel carboxylic acid derivatives, their preparation and use.
Endothelin is a peptide which is composed of 21 amino acids and is synthesized and released by the vascular endothelium. Endothelin exists in three isoforms, ET-1, ET-2 and ET-3. Endothelin or ET hereinafter indicates one or all isoforms of endothelin. Endothelin is a potent vasoconstrictor and has a great effect on vascular tone. It is known that this vasoconstriction is caused by the binding of endothelin to its receptor (Nature, 332, 411-415, 1988; FEBS Letters, 231, 440-444, 1988 and Biochem. Biophys. Res. Commun., 154, 868-875, 1988).
Increased or abnormal release of endothelin causes persistent vasoconstriction in peripheral, renal and cerebral blood vessels, which may lead to diseases. As reported in the literature, elevated levels of endothelin in plasma have been found in patients with hypertension, acute myocardial infarct, pulmonary hypertension, Raynaud's syndrome, atherosclerosis and in the airways of asthmatics (Japan J. Hypertension, 12, 79 (1989), J. Vascular Med. Biology 2, 207 (1990), J. Am. Med. Association 264, 2868 (1990)).
Accordingly, substances which specifically inhibit the binding of endothelin to the receptor should also antagonize the various abovementioned physiological effects of endothelin and therefore be valuable drugs.
It has been found (WO 94/02474) that certain carboxylic acid derivatives with the general formula Q are good inhibitors of endothelin receptors ##STR2##
However, this related mainly to compounds with a double bond in the molecule. Besides R.sup.A and R.sup.B, a maximum of one hydrogen atom is permitted on the .beta. center.
It has now been found, surprisingly, that this hydrogen atom can be replaced by alkyl radicals. This results in a quaternary .beta. center with, at the same time, a large increase in the activity with regard to endothelin receptors (see Examples).
The invention relates to carboxylic acid derivatives of the formula I ##STR3## where R.sup.1 is a tetrazole [sic], nitrile [sic], COOH or a radical which can be hydrolyzed to COOH, and the other substituents have the following meanings:
R.sup.2 and R.sup.3 (which can be identical or different):

phenyl or naphthyl which are connected together in the ortho positions by a direct linkage, a methylene, ethylene or ethenylene group, or an oxygen or sulfur atom;
R.sup.4 phenyl or naphthyl, methylenedioxyphenyl, ethylenedioxyphenyl, indanyl, indolyl, pyridyl, benzopyranyl, furanyl, benzofuranyl, isooxazolyl, isothiazolyl, 1,3,4-thiadiazolyl, pyrimidinyl, 2,3-dihydrobenzofuranyl, benzothienyl, quinolinyl, C.sub.3 -C.sub.7 -cycloalkyl, thienyl, oxazolyl, thiazolyl, each of which can be substituted by one or more of the following radicals: halogen, cyano, hydroxyl, NO.sub.2, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, phenoxy, C.sub.1 -C.sub.4 -alkylthio, amino, benzyloxy, C.sub.1 -C.sub.4 -alkylamino or C.sub.1 -C.sub.4 -dialkylamino, it being possible for the alkyl radicals together to form a ring;
R.sup.5 C.sub.1 -C.sub.8 -alkyl, C.sub.3 -C.sub.6 -alkenyl, C.sub.3 -C.sub.6 -alkynyl or C.sub.3 -C.sub.8 -cycloalkyl, it being possible for each of these radicals to be substituted one or more times by: halogen, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -alkylamino, di-C.sub.1 -C.sub.4 -alkylamino;

The compounds, and the intermediates for preparing them, such as Va, may have one or more asymmetric substituted carbon atoms. Compounds of this type may be in the form of pure enantiomers or pure diastereomers or of a mixture thereof. The use of an enantiomerically pure compound as agent is preferred.
The invention furthermore relates to the use of the abovementioned carboxylic acid derivatives for producing drugs, in particular for producing inhibitors of endothelin receptors.
Compounds of the formula I can be prepared by initially reacting a ketone of type II with a phosphono ester of the formula III in the presence of a base to give compounds of the formula IV ##STR4##
Aprotic polar solvents such as DMF or TRF are used as solvent.
It is possible to use as base an alkali metal or alkaline earth metal hydride such as sodium hydride, potassium hydride or calcium hydride, a carbonate such as alkali metal carbonate, eg. sodium or potassium carbonate, an alkali metal or alkaline earth metal hydroxide such as sodium or potassium hydroxide, an organometallic compound such as butyllithium, an alkali metal alcoholate such as sodium ethanolate or potassium tert-butanolate or an alkali metal amide such as lithium diisopropylamide.
The reaction is preferably carried out at a temperature in the range from 0.degree. C. to the boiling point of the solvent or solvent mixture.
The compounds of type IV can then be reacted with aromatic compounds in the presence of a catalyst to give carboxylic acid derivatives of the general formula Va ##STR5##
Suitable catalysts for this are strong inorganic acids and Lewis acids. Examples thereof are, inter alia, sulfuric acid, aluminum trichloride, zinc chloride or iron trichloride. When sulfuric acid is used, the free acid can be obtained directly.
Alternatively, symmetrical carboxylic acid derivatives of the formula Vb can be prepared from a .beta.-dicarbonyl compound VI and an aromatic compound in the presence of a catalyst. ##STR6##
Suitable catalysts for this are strong inorganic acids and Lewis acids. Examples thereof are, inter alia, sulfuric acid, aluminum trichloride, zinc chloride or iron trichloride (see also: Gogte G. R. et al., J. Univ. Bombay, Sect. A, 27, 1958, 41).
Another possibility for preparing compounds of type Va can start from a ketone VII ##STR7## which can be reacted with Meldrum's acid in the presence of a base such as pyridine or sodium hydride to give compounds of type VIII ##STR8##
Reaction of compounds of type VIII in diethyl ether with a Grignard reagent of the general formula IX
R.sup.3 --Mg Y (IX)
Y.dbd.Br, Cl, I (IX)
results in compounds of type X ##STR9## in which case it may be advantageous to use in addition copper salts such as copper chloride, copper bromide, copper iodide or copper cyanide and for a Lewis acid such as trimethylsilyl chloride or boron trifluoride etherate to be present.
Hydrolysis of compounds of the formula X with mineral acids such as hydrochloric acid or sulfuric acid can then afford the compounds Va (R.dbd.OH).
Further possibilities for preparing compounds Va are similar to the methods of Zimmermann H. E. et al. J. Am. Chem, Soc. 83 (1961) 1196 or Yu A.J. et al. J. Org. Chem. 23 (1958) 1004.
Compounds of the formula Va,b can be converted into the anion (or dianion for R.dbd.H) with a strong base such as butyllithium or lithium diisopropylamide in an inert solvent such as diethyl ether or tetrahydrofuran and under inert gas, eg. nitrogen or argon, at -78.degree. C. to room temperature. This anion reacts with alkylating agents of type VII at -78.degree. C. to room temperature.
Quenching with concentrated NH.sub.4 Cl or dilute mineral acid such as HCl results in compounds of the formula I ##STR10##
Compounds of type I with R.sup.1 =tetrazole [sic] can be synthesized starting from the carboxylic acids I (R.sup.1 .dbd.COOH). To do this, the carboxylic acid is reacted with thionyl chloride at room temperature to give the acid chloride, which is then reacted with aqueous ammonia solution to give the amide of the formula XII. ##STR11##
Amides of the formula XII can be reacted with oxalyl chloride or phosphorus oxychloride or trifluoroacetic anhydride in DMF or pyridine at 0.degree. C. to room temperature to give nitriles of the formula XIII ##STR12##
Reaction of nitriles of the formula XIII with sodium azide or trimethylsilyl azide in a suitable solvent such as dimethylformamide, tetrahydrofuran or 1-methyl-2-pyrrolidinone in the presence of a catalyst such as ammonium chloride (see also: Bernsteim P. R. et al., Synthesis, 1987, 1133) at room temperature or elevated temperature affords the tetrazoles XIV ##STR13##
Compounds of the formula I can also be prepared by starting from the corresponding carboxylic acids, ie. compounds of the formula I where R.sup.1 .dbd.COOH, and converting these initially in a conventional way into an activated form such as an acid halide, an anhydride or imidazolide, and then reacting the latter with an appropriate hydroxyl compound HOR. This reaction can be carried out in conventional solvents and often requires the addition of a base, in which case those mentioned above are suitable. These two steps can also be simplified, for example, by allowing the carboxylic acid to act on the hydroxyl compound in the presence of a dehydrating agent such as a carbodiimide.
Compounds of the formula I can also be prepared by starting from salts of the corresponding carboxylic acids, ie. from compounds of the formula I where R.sup.1 is COR and R is OM, where M can be an alkali metal cation or the equivalent of an alkaline earth metal cation. These salts can be reacted with many compounds of the formula R-A where A is a conventional nucleofugic leaving group, for example halogen such as chlorine, bromine, iodine, or aryl- or alkylsulfonyl which is unsubstituted or substituted by halogen, alkyl or haloalkyl, such as toluenesulfonyl and methylsulfonyl, or another equivalent leaving group. Compounds of the formula R-A with a reactive substituent A are known or can easily be obtained with general expert knowledge. This reaction can be carried out in the usual solvents and is advantageously carried out with the addition of a base, in which case those mentioned above are suitable.
Enantiomerically pure compounds of the formula I can be obtained by carrying out with racemic or diastereomeric compounds of the formula VI a classical racemate resolution with suitable enantiomerically pure bases such as brucine, strychnine, quinine, quinidine, cinchonidine, cinchonine, yohimbine, morphine, dehydroabietylamine, ephedrine (-), (+), deoxyephedrine (-) (+) threo-2-amino-1-(p-nitrophenyl)-1,3-propanediol (-) , (+), threo-2-(N,N-dimethylamino)-1-(p-nitrophenyl)-1,3-propanediol (+), (-) threo-2-amino-1-phenyl-1,3-propanediol (+), (-) .alpha.-methylbenzylamine (+), (-) , .alpha.-(1-naphthyl)ethylamine (+), (-) .alpha.-(2-naphthyl)ethylamine (+), (-) , aminomethylpinane, N,N-dimethyl-1-phenylethylamine, N-methyl-1-phenylethylamine, 4-nitrophenylethylamine, pseudoephedrine, norephedrine, norpseudoephedrine, amino acid derivatives and peptide derivatives.

b) a 5-membered heteroaromatic radical which is linked via a nitrogen atom, such as pyrrolyl, pyrazolyl, imidazolyl and triazolyl, and which can carry one or two halogen atoms, especially fluorine and chlorine, and/or one or two of the following radicals:

The compounds of the present invention provide a novel therapeutic potential for the treatment of hypertension, pulmonary hypertension, myocardial infarct, angina pectoris, acute kidney failure, renal insufficiency, cerebral vasospasms, cerebral ischemia, subarachnoid hemorrhages, migraine, asthma, atherosclerosis, endotoxic shock, endotoxin-induced organ failure, intravascular coagulation, restenosis after angioplasty, benign prostate hyperplasia, kidney failure caused by ischemia and by intoxication, and hypertension.
The good effect of the compounds can be shown in the following tests:
Receptor-Binding Studies
Cloned human ET.sub.A receptor-expressing CHO cells and guinea pig cerebellar membranes with >60% ETB receptors by comparison with ET.sub.A receptors were employed for binding studies.
Membrane Preparation
The ET.sub.A receptor-expressing CHO cells were grown in F.sub.12 medium containing 10% fetal calf serum, 1% glutamine, 100 U/ml penicillin and 0.2% streptomycin (Gibco BRL, Gaithersburg, Md., USA). After 48 h, the cells were washed with PBS and incubated with 0.05% trypsin-containing PBS for 5 min. Then neutralization was carried out with F.sub.12 medium, and the cells were collected by centrifugation at 300.times.g. To lyse the cells, the pellet was briefly washed with lysis buffer (5 mM tris-HCl, pH 7.4 with 10% glycerol) and then incubated at a concentration of 10.sup.7 cells/ml of lysis buffer at 4.degree.-C. for 30 min. The membranes were centrifuged at 20,000.times.g for 10 min, and the pellet was stored in liquid nitrogen.
Guinea pig cerebella were homogenized in a Potter-Elvejhem homogenizer and obtained by differential centrifugation at 1,000.times.g for 10 min and repeated centrifugation of the supernatant at 20,000.times.g for 10 min.
Binding Assays
For the ET.sub.A and ET.sub.B receptor binding assay, the membranes were suspended in an incubation buffer (50 mM tris-HCl, pH 7.4, with 5 mM MnCl.sub.2, 40 .mu.g/ml bacitracin and 0.2% BSA) at a concentration of 50 .mu.g of protein per assay mixture and incubated in the presence and absence of test substance with 25 pM .sup.125 I-ET.sub.1 (ET.sub.A receptor assay) or 25 pM .sup.125 -RZ.sub.3 (ETB receptor assay) at 25.degree. C. The nonspecific binding was determined with 10.sup.-7 M ET.sub.1. After 30 min, the free and bound radioligand were separated by filtration through GF/B glass fiber filters (Whatman, England) on a Skatron cell collector (Skatron, Lier, Norway), and the filters were washed with ice-cold tris-HCl buffer, pH 7.4 with 0.2% BSA. The radioactivity collected on the filters was quantified using a Packard 2200 CA liquid scintillation counter.
Functional in vitro assay system for searching for endothelin receptor (subtype A) antagonists
This assay system is a functional, cell-based assay for endothelin receptors. Certain cells show, when they are stimulated with endothelin 1 (ET1), an increase in the intracellular calcium concentration. This increase can be measured in intact cells which have been loaded with calcium-sensitive dyes.
1-Fibroblasts which were isolated from rats and in which an endogenous endothelin receptor of the A subtype had been detected were loaded with the fluorescent dye Fura 2-an as follows: after tripysinization, the cells were resuspended in buffer A (120 mM NaCl, 5 mM KCL, 1.5 mM MgCl.sub.2, 1 mM CaCl.sub.2, 25 mM HEPES, 10 mM Glucose, pH 7.4) to a density of 2.times.10.sup.6 /ml and incubated with Fura-2-am (2 .mu.M), Pluronic F-127 (0.04%) and DMSO (0.2%) at 37.degree. C. in the dark for 30 min. The cells were then washed twice with buffer A and resuspended at 2.times.10.sup.6 /ml.
The fluorescence signal from 2.times.10.sup.5 cells per ml with Ex/Em 380/510 was recorded continuously at 30.degree. C. The test substances and, after an incubation time of 3 min, ET1 were added to the cells. The maximum change in the fluorescence was determined over 30 min. The response of the cells to ET1 without previous addition of a test substance served as control and was set equal to 100%.
In Vivo Testing of ET Antagonists
Male SD rats weighting 250-300 g were anesthetized with amobarbital, artificially ventilated, vagotomized and pithed. The carotid artery and the jugular vein were catheterized.
Intravenous administration of 1 .mu.g/kg ET1 to control animals leads to a distinct rise in blood pressure which persists for a lengthy period.
The test compounds was [sic] injected i.v. (1 ml/kg) into the test animals 5 or 30 min before ET1 administration. To determine the ET-antagonistic properties, the increase in blood pressure in the test animals was compared with that in the control animals.
Endothelin-1 Induced Sudden Death in Mice
The principle of the test comprises the inhibition of the sudden heart death in mice which is caused by endothelin, probably due to constriction of the coronary vessels, by pretreatment with endothelin receptor antagonists. Intravenous injection of 10 nmol/kg endothelin in a volume of 5 ml/kg of body weight results in death of the animals within a few minutes.
The lethal endothelin-1 dose is checked in each case on a small group of animals. If the test substance is administered intravenously, it is usually followed after 5 min by the endothelin-1 injection which was lethal in the reference group. With other modes of administration, the times before administration are longer, where appropriate up to several hours.
The survival rate is recorded and effective doses which protect 50% of the animals for 24 h or longer against endothelin-induced heart death (ED 50) are determined.
Functional Test for Endothelin Receptor Antagonists on Vessels
Segments of rabbit aorta with an initial tension of 2 g and a relaxation time of 1 h in Krebs-Henseleit solution at 37.degree. C. and at a pH of from 7.3 to 7.4 are initially induced to contract with K.sup.+. After washing out, an endothelin dose-effect plot is constructed up to the maximum.
Potential endothelin antagonists are administered to other preparations of the same vessel 15 min before starting the endothelin dose-effect plot. The effects of endothelin are calculated as a % of the K.sup.+ contraction. Effective endothelin antagonists result in a shift in the endothelin dose-effect plot to the right.
The compounds according to the invention can be administered orally or parenterally (subcutaneously, intravenously, intramuscularly, intraperitoneally) in a conventional way. Administration can also take place with vapors or sprays through the nasopharyngeal space.
The dosage depends on the age, condition and weight of the patient and on the mode of administration. As a rule, the daily dose of agent is about 0.5-50 mg/kg of body weight on oral administration and about 0.1-10 mg/kg of body weight on parenteral administration.
The novel compounds can be used in conventional solid or liquid pharmaceutical forms, eg. as uncoated or (film-)coated tablets, capsules, powders, granules, suppositories, solutions, ointments, creams or sprays. These are produced in a conventional way. The agents can for this purpose be processed with conventional pharmaceutical aids such as tablet binders, bulking agents, preservatives, tablet disintegrants, flow regulators, plasticizers, wetting agents, dispersants, emulsifiers, solvents, release-slowing agents, antioxidants and/or propellant gases (cf. H. Sucker et al.: Pharmazeutische Technologie, Thieme-Verlag, Stuttgart, 1991). The administration forms obtained in this way normally contain from 0.1 to 90% by weight of the agent.

SYNTHETIC EXAMPLES
Example 1

a) Ethyl (2E,Z)-3-(4-methoxyphenyl)-2-butenoate (6.6 g, 30 mmol) were dissolved in anisole (4.9 g, 45 mmol) at 0.degree. C., and 50 ml of 80% H2SO.sub.4 were cautiously added. The 2-phase mixture was vigorously stirred at room temperature for 20 h and then poured onto ice, and the product was extracted with ethyl acetate. The organic phase was dried (Na.sub.2 SO.sub.4), filtered and concentrated, the residue was taken up with ether and extracted with 2N sodium hydroxide solution, and the ether phase was discarded. The alkaline phase was adjusted to pH 2 with 2N HCl, and the product was extracted with ethyl acetate. The organic phase was then dried (Na.sub.2 SO.sub.4), filtered and concentrated, and the solid residue was stirred with diisopropyl ether. The product was filtered off with suction and dried. 5.1 g of a white powder (56%) remained.
Melting point: 161-164.degree. C.
Further working up of the mother liquor was possible, resulting in a further 1.1 g (12%) of the acid.
The acid can also be prepared by the following alternative:

The mixture was then quenched with saturated NH.sub.4 Cl solution, the organic phase was separated off and the aqueous was extracted with ethyl acetate. The combined organic extracts were dried (Na.sub.2 SO.sub.4), filtered and concentrated in a rotary evaporator. The brown residue was chromatographed on silica gel (methanol/CH.sub.2 Cl.sub.2 1:19), resulting in 1.3 g (30%) of product as a white foam.
