Description

Growing importance is attached to the development of novel angiotensin II receptor antagonists. 1-Benzyl-substituted imidazole derivatives are known from EP-A-28,834, imidazole derivatives having a diarylcarboxylic function are known from EP-A-253,310 and EP-A-0,401,030, pyrazole and triazole derivatives are known from EP-A-323,841 and triazole derivatives in each case having a diarylcarboxylic function are known from EP-A-0,409,332, and imidazole derivatives having a diaryltetrazolyl group and their use as antagonists of angiotensin II receptors are known from EP-A-324,377.

Moreover, substituted azoles which contain a sulfonylurea group are presented in DE-A-4,010,797 (corresponding to U.S. patent application No. 07/679.233).

Novel azole derivatives have been found which have a novel sulfonylurea, sulfonylurethane or a sulfonylsulfonamide structure and which are highly active antagonists of angiotensin II receptors both in vitro and in vivo.

and their physiologically tolerable salts with the exception of the compound of the formula .alpha. ##STR12##

Alkyl, alkenyl and alkynyl can be straight-chain or branched. The same applies to radicals derived therefrom, such as alkanoyl or alkoxy.

Cycloalkyl is also understood as meaning alkyl-substituted rings.

(C.sub.6 -C.sub.12)-aryl is, for example, phenyl, naphthyl or biphenylyl, preferably phenyl. The same applies to radicals derived therefrom, such as aroyl or aralkyl.

(C.sub.1 -C.sub.9)-heteroaryl is in particular understood as meaning radicals which are derived from phenyl or naphthyl, in which one or more CH groups are replaced by nitrogen and/or in which at least two adjacent CH groups are replaced (with the formation of a five-membered aromatic ring) by S, NH or O. In addition, one or two atoms of the condensation site of bicyclic radicals (such as in indolizinyl) can also be nitrogen atoms.

Heteroaryl is in particular also furanyl, thienyl, pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, thiazolyl, isothiazolyl, pyridyl, pyrazinyl, pyrimidinyl, pyridazinyl, indolyl, indazolyl, quinolyl, isoquinolyl, phthalazinyl, quinoxalinyl, quinazolinyl and cinnolinyl.

Stereocenters which may occur can be of both (R) and (S) configuration.

The linkage of A takes place via an alkanediyl bridge L which is preferably a methylene group.

The methylene group is preferably directly bonded to the biphenyl radical.

Physiologically tolerable salts of compounds of the formula (I) are understood as meaning both their organic and their inorganic salts, such as are described in Remington's Pharmaceutical Sciences (17th edition, page 1418 (1985)). Owing to the physical and chemical stability and the solubility, sodium, potassium, calcium and ammonium salts, inter alia, are preferred for acid groups; salts of hydrochloric acid, sulfuric acid, phosphoric acid or of carboxylic acids or sulfonic acids, such as, for example, acetic acid, citric acid, benzoic acid, maleic acid, fumaric acid, tartaric acid and p-toluenesulfonic acid, inter alia, are preferred for basic groups.

q is zero and r is zero, 1 or 2, and their physiologically tolerable salts.

The invention also relates to a process for the preparation of compounds of the formula (I), and of their physiologically tolerable salts, which comprises alkylating compounds of the formula (II) ##STR16## in which R.sup.1, X, Y and Z are as defined above, with compounds of the formula (III)

U--L--(O).sub.q --A (III) in which L, A and q are as defined above, and U is a leaving group, if appropriate removing temporarily introduced protective groups and converting sulfonamides of the formula I obtained, if appropriate, into urethanes of the formula I, converting sulfonamides of the formula I obtained or urethanes of the formula I obtained, if appropriate, into sulfonylureas of the formula I and converting the compounds of the formula (I) obtained, if appropriate, into their physiologically tolerable salts.

Suitable leaving groups U are preferably nucleofugic groups (cf. Angew. Chem. 72 [1960] 71) such as halogen, o-toluenesulfonate, mesylate or triflate.

Processes for the preparation of the precursors of the formula (II) are known, inter alia, from U.S. Pat. No. 4,355,044, EP-A-324,377 and EP-A-323,841.

Other processes are described by G. L'abbe (Chem. Rev. 69, 345 (1969)), T. Srodsky ("The Chemistry of the Azido Group", Wiley, New York, 1971, p. 331), H. Wamhoff ("Comprehensive Heterocyclic Chemistry") and by S. Katritzky Ed., Pergamon Press, New York (1984)).

Another process for the preparation of compounds of the formula II starts from 1-cyanoglyoxylic acid 2-oxime derivatives and after reduction of the oxime with reductants known from the literature and addition of mercapto compounds to the nitrile group using suitable protective groups yields precursors which can be cyclized under dehydrating conditions to give imidazoles. For the cyclization step, inter alia, mixtures of PCl.sub.5 and dimethylaminopyridine (DMAP), POCl.sub.3 and SOCl.sub.2 and their mixtures with DMAP can be used.

The oxidation of the thio compounds of the formula I where R.sup.2 is --S(O).sub.r R.sup.19 and in which R is zero or 1 to the corresponding sulfones and sulfoxides is preferably carried out by means of peracids in suitable solvents such as, for example, dichloromethane.

To alkylate the azoles of the formula (II), suitable alkylating agents are, for example, appropriate benzyl halides, tosylates, mesylates or triflates or appropriate alkyl halides, tosylates, mesylates or triflates.

The alkylation is carried out in an analogous manner to processes which are known in principle.

Azole derivatives of the formula (II) are metalated, for example, in the presence of a base. Preferred bases are metal hydrides of the formula MH such as, for example, lithium hydride, sodium hydride or potassium hydride in, for example, DMF or DMSO as a solvent or metal alkoxides of the formula MOR, where R is methyl, ethyl or t-butyl, and the reaction is carried out in the corresponding alcohol, DMF or DMSO. The salts of the azoles thus formed are dissolved in an aprotic solvent such as DMF or DMSO and treated with a suitable amount of alkylating reagent.

An alternative possibility for the deprotonation of the azole derivatives is, for example, reaction with potassium carbonate in DMF or DMSO.

The reactions are carried out at temperatures below room temperature up to the boiling point of the reaction mixture, preferably between +20.degree. C. and the boiling point of the reaction mixture, for about 1 to 10 hours.

The biphenyl derivatives can be synthesized, for example, starting from arylboronic acid derivatives by coupling with substituted aryl halides using transition metal catalysts, in particular palladium. Corresponding reactions are described by R. B. Miller et al. (Organometallics 1984, 3, 1261) or by A. Zuzuki et al. (Synthetic Commun. 11 (7), 513 (1981)).

The sulfonylurethanes of the formula I can be obtained from appropriate sulfonamides of the formula I by reaction with chlorocarbonic acid esters in inert high-boiling solvents such as, for example, toluene at temperatures of about 100.degree. C. or the boiling points of the appropriate solvents.

Analogously, sulfonyl-sulfonamides can be prepared from the appropriate sulfonamides by reaction with sulfonyl chlorides or sulfamoyl chlorides.

The sulfonamide radical can be prepared by means of Meerwein reaction, if necessary, starting from an amino group. For this, the hydrochloride of the amine is first diazotized and then reacted with sulfur dioxide in glacial acetic acid in the presence of a copper catalyst. Subsequent action of ammonia leads to the sulfonamido group.

Alternatively, an appropriate thiophenol can be converted into a sulfonamide by oxidation with chlorine and subsequent action of ammonia.

The compounds of the formula (I) according to the invention have antagonistic action on angiotensin II receptors and can therefore be used for the treatment of angiotensin II-dependent hypertension. Possibilities of application furthermore exist in cardiac insufficiency, cardioprotection, myocardial infarct, cardiac hypertrophy, arteriosclerosis, nephropathy, kidney failure and vascular diseases of the brain such as transitory ischemic attacks and stroke.

Renin is a proteolytic enzyme of the aspartylprotease class, which is secreted into the blood circulation by the juxtaglomerular cells of the kidney as a consequence of various stimuli (volume depletion, sodium deficiency, .beta.-receptor stimulation). In the blood, it cleaves the decapeptide angiotensin I from the angiotensinogen excreted from the liver. The former is converted into angiotensin II by the "angiotensin-converting enzyme" (ACE). Angiotensin II plays an essential role in blood pressure regulation, as it directly increases the blood pressure by means of vascular contraction. It additionally stimulates the secretion of aldosterone from the adrenal gland and in this way increases the extracellular fluid volume via the inhibition of sodium excretion, which for its part contributes to an increase in blood pressure.

Post-receptor actions are inter alia stimulation of phosphoinositol conversion (Ca.sup.2+ release), activation of protein kinase C) and facilitation of c-E-dependent hormone receptors.

The affinity of the compounds of the formula I for the angiotensin II receptor can be determined by measurement of .sup.125 I-angiotensin II or .sup.3 H-angiotensin II displacement from receptors on membranes of the zona glomerulosa of bovine adrenal glands. For this purpose, the prepared membranes are suspended in buffer at pH 7.4.

Aprotinin, a peptidase inhibitor, is added in order to prevent the degradation of the radioligand during the incubation. About 14000 cpm of a tracer having a specific activity of 74 TBq/mmol (available from Amersham Buchler, Braunschweig, FRG) and a quantity of receptor protein which binds 50% of the tracer are additionally used. The reaction is begun by addition of 50 .mu.l of membrane suspension to a mixture of 100 .mu.l of buffer+aprotinin, 50 .mu.l of buffer with or without angiotensin II or receptor antagonist and 50 .mu.l of tracer. After an incubation time of 60 minutes at a temperature of 25.degree. C., bound and free radioligand are separated on a Skatron.RTM. cell collector using Whatmann.RTM. GFIC filters by means of a filtration assay.

Non-specific binding is prevented by treatment of the filter with 0.3% polyethyleneimine pH=10 (Sigma, No. 3143).

The amount of displacement of the radioligand from the receptor is determined by measurement of the radioactivity in a gamma scintillation counter. The IC.sub.50 values, which denote the concentration of inhibitor for displacing 50% of the ligand, are determined according to J. Theor. Biol. 59, 253 (1970). For the compounds of the formula (I) they are in the range from 1.times.10.sup.-4 -1.times.10.sup.-9 M.

Alternatively, the affinity of the compounds of the formula I for the angiotensin II receptor can be determined by measurement of the .sup.125 I-angiotensin II or .sup.3 H-angiotensin II displacement of receptor preparations from various organs (liver, lung, adrenal gland, brain etc.).

To this end, the prepared membranes are suspended in an incubation buffer (20 mm Tris, pH 7.4, containing 135 mM NaCl, 10 mM KCl, 10 mM MgCl.sub.2, 5 mM glucose, 0.2% bovine serum albumin and the protease inhibitors PMSF, 0.3 mM, and bacitracin, 0.1 mM) and incubated at 25.degree. C. for 90 min together with the radioactively labeled angiotensin II and various concentrations of the compounds to be tested. Bound and free radioligand are then separated by filtration through micro glass fiber filters (GF51, Schleicher and Schull) in a cell collector (SKATRON).

The degree of displacement of the radioligand from the receptor by the test compounds is determined by measurement of the receptor-bound radioactivity on the filters by means of a beta- or gamma-spectrometer. The amount of the displacement of the radioligand from the receptor by the test compounds is indicated by the IC.sub.50, i.e. the concentration of the inhibitor which displaces 50% of the bound radioligand from the receptor. The calculation of the IC.sub.50 values is carried out by means of PC software (LIGAND, G. A. McPherson 1985, Elsevier BIOSOFT, 68 Hills Road, Cambridge, CB2 1LA, UK.). The IR.sub.50 values measured for compounds of the formula (I) are in the range from 1.times.10.sup.-5 to 1.times.10.sup.-11 M (Table 1 which follows, in which the IC.sub.50 values are collated for compounds according to the invention).

To determine the antagonistic action of the compounds of the formula (I), their effect on the angiotensin II-induced blood pressure rise in anesthetized Sprague-Dawley rats can be measured. Na thiobarbital (Trapanal.RTM., trademark of Byk Gulden, FRG) is used as an anesthetic in the dose 100 mg/kg J.p. i.v. administration is carried out in the jugular vein. The blood pressure is measured in the carotid artery. The animals are first pretreated with pentoliniumtartrate (10 mg/kg i.m.) so that a lower blood pressure level is achieved (ganglia blockade). ANG II (Hypertensin CIBA) is administered i.v. in the volume 0.1 ml/100 g at 10 minute intervals. The dose is 0.5 .mu.g/kg. The compounds of the formula (I) are dissolved in distilled water and administered intravenously or intraduodenally in the doses 0.1 to 1.0 mg/kg, or 10 and 100 mg/kg respectively.

The compounds of the formula (I) are particularly effective in the range from 0.1-100 mg/kg, preferably 0.1-3 mg/kg.

The invention also relates to pharmaceutical compositions comprising a compound of the formula (I) and other active compounds, such as, for example, diuretics or non-steroidal anti-inflammatory active compounds. The compounds of the formula (I) can also be used as diagnostics for the renin-angiotensin system.

Pharmaceutical preparations contain an effective amount of the active compound of the formula (I) and if necessary other active compounds together with an inorganic or organic pharmaceutically utilizable excipient. Administration can be carried out intranasally, intravenously, subcutaneously or orally. The dosage of the active compound depends on the mammalian species, the body weight, the age and the manner of administration.

The pharmaceutical preparations of the present invention are prepared in a dissolving, mixing, granulating or coating process known per se.

For a form for oral administration, the active compounds are mixed with the additives customary therefor such as excipients, stabilizers or inert diluents and brought by means of customary methods into suitable administration forms such as tablets, coated tablets, hard gelatin capsules, aqueous, alcoholic or oily suspensions or aqueous, alcoholic or oily solutions. Inert excipients which can be used are, for example, gum arabic, magnesia, magnesium carbonate, potassium phosphate, lactose, glucose, magnesium stearyl fumarate or starch, in particular maize starch. The preparation in this case can be dry and moist granules. Suitable oily excipients or solvents are, for example, vegetable or animal oils, such as sunflower oil and cod liver oil.

For subcutaneous or intravenous administration, the active compounds or their physiologically tolerable salts are brought into solutions, suspensions or emulsions, if appropriate with the substances customary therefor such as solubilizers, emulsifiers or other auxiliaries. Suitable solvents are, for example, water, physiological saline solution or alcohols, such as ethanol, propanediol or glycerol, and sugar solutions such as glucose or mannitol solutions or mixtures of said solvents.

EXAMPLE 1

Synthesis of 1-[(2'-phenylaminocarbonylaminosulfonylbiphenyl-4-yl)methyl]-2-n-butyl-4-chloroimidazole-5-carboxaldehyde ##STR17##

a) Preparation of 4'-methylbiphenyl-2-amine

3 g of Raney nickel are added to 23.9 g (0.112 mol) of 4'-methyl-2-nitrobiphenyl (R. B. Muller and S. Dugar, Organometallics 1984, 3, 1261) in 50 ml of methanol and the mixture is hydrogenated under normal pressure at room temperature until the theoretical amount of H.sub.2 has been absorbed. The catalyst is then removed by filtration and the filtrate is concentrated. Chromatography on SiO.sub.2 (500 g) using EA/HEP(1:6) as the eluent yields 19 g of the title compound as an oil (92.5%)

R.sub.f (EA/HEP 1:4)=0.3 MS(EI)=183 (M.sup.+)

b) 4'-Methylbiphenyl-2-ammonium hydrochloride

10 g of compound 1a) are dissolved in 50 ml of 6N HCl and 100 ml of dioxane. Removal of the solvent by distillation yields the title compound, which is used without further purification.

c) 4'-Methylbiphenyl-2-sulfonamide

7.9 g (114 mmol) of sodium nitrite are added at -10.degree. C. to a suspension of 31 g (140 mmol) of compound 1b) in 200 ml of 6N HCl, a clear solution being formed. This is added at 0.degree. C. to a solution containing 200 ml of glacial acetic acid, saturated with SO.sub.2, 17 g of CuCl.sub.2.H.sub.2 O and 25 ml of H.sub.2 O.
