Forbindelsene kan fremstilles etter følgende fremgangsmåter: The compounds can be produced according to the following methods:
a) cyklisering av en eventuelt i reaksjonsblandingen dannet forbindelse med den generelle formel a) cyclization of an optionally formed compound of the general formula in the reaction mixture
hvor where
R-l og R2 er som innledningsvis definert, R-1 and R2 are, as initially defined,
en av restene X,, eller Y1 utgjør en gruppe med den generelle formel one of the residues X,, or Y1 constitutes a group of the general formula
og den andre av restene Xx eller Yx utgjør en gruppe med den generelle formel and the second of the residues Xx or Yx constitutes a group of the general formula
hvor R3 og R4 er som innledningsvis definert, where R3 and R4 are as initially defined,
R5 er et hydrogenatom eller en R3CO-gruppe, hvor R3 er som definert ovenfor, R5 is a hydrogen atom or an R3CO group, where R3 is as defined above,
Zi og Z2, som kan være like eller forskjellige, utgjør eventuelt med alkylgrupper, med 1 til 6 karbonatomer, substituerte amino-, hydroksy- eller merkaptogrupper, eller zi og Z2 sammen, et oksygen- eller svovelatom, en iminogruppe som eventuelt er substituert med en alkylgruppe med 1 til 3 karbonatomer, en alkylendioksy- eller alkylenditiogruppe som hver har 2 eller 3 karbonatomer. Zi and Z 2 , which may be the same or different, optionally with alkyl groups, with 1 to 6 carbon atoms, constitute substituted amino, hydroxy or mercapto groups, or zi and Z 2 together, an oxygen or sulfur atom, an imino group optionally substituted with an alkyl group of 1 to 3 carbon atoms, an alkylenedioxy or alkylenedithio group each having 2 or 3 carbon atoms.
Cykliseringen foretas hensiktsmessig i et oppløsnings-middel eller i en oppløsningsmiddelblanding som etanol, isopropanol, iseddik, benzen, klorbenzen, toluen, xylen, glykol, glykolmonometyleter, dietylenglykol-dimetyleter, sulfolan, dimetylformamid, tetralin eller i et overskudd av det acyleringsmiddel som benyttes for fremstilling av forbindelsen med den generelle formel II, f.eks. i det tilsvarende nitril, anhydrid, syrehalogenid, ester eller amid, eksempelvis ved temperaturer mellom 0 og 250°C, men fortrinnsvis ved reaksjonsblandingens kokepunkt, eventuelt i nærvær av et kondensasjonsmiddel som fosforoksyklorid, tionylklorid, sulfurylklorid, svovelsyre, p-toluensulfonsyre, metan-sulfonsyre, saltsyre, fosforsyre, polyfosforsyre, eddiksyre-anhydrid, eller eventuelt også i nærvær av en base som kalium-etylat eller kalium-tert-butylat. Cykliseringen kan imidlertid også foretas uten oppløsningsmiddel og/eller kondensasjonsmiddel . The cyclization is conveniently carried out in a solvent or in a solvent mixture such as ethanol, isopropanol, glacial acetic acid, benzene, chlorobenzene, toluene, xylene, glycol, glycol monomethyl ether, diethylene glycol dimethyl ether, sulfolane, dimethylformamide, tetralin or in an excess of the acylating agent used for preparation of the compound of the general formula II, e.g. in the corresponding nitrile, anhydride, acid halide, ester or amide, for example at temperatures between 0 and 250°C, but preferably at the boiling point of the reaction mixture, possibly in the presence of a condensation agent such as phosphorus oxychloride, thionyl chloride, sulphuryl chloride, sulfuric acid, p-toluenesulfonic acid, methane sulphonic acid, hydrochloric acid, phosphoric acid, polyphosphoric acid, acetic anhydride, or optionally also in the presence of a base such as potassium ethylate or potassium tert-butylate. However, the cyclization can also be carried out without a solvent and/or condensing agent.
Særlig fordelaktig foretas omsetningen slik at en forbindelse med den generelle formel II fremstilles i reaksjonsblandingen ved reduksjon av en tilsvarende o-nitroamino-forbindelse, eventuelt i nærvær av en karboksylsyre med den generelle formel R3COOH, eller ved acylering av en tilsvarende o-diaminoforbindelse. Ved å stanse reduksjonen av nitrogruppen på hydroksylamintrinnet, oppnår man ved den påfølgende cyklisering N-oksydet av en forbindelse med den generelle formel I. Det således oppnådde N-oksyd overføres deretter ved reduksjon i en tilsvarende forbindelse med den generelle formel I. Particularly advantageously, the reaction is carried out so that a compound of the general formula II is produced in the reaction mixture by reduction of a corresponding o-nitroamino compound, optionally in the presence of a carboxylic acid of the general formula R3COOH, or by acylation of a corresponding o-diamino compound. By stopping the reduction of the nitro group in the hydroxylamine step, the N-oxide of a compound of the general formula I is obtained in the subsequent cyclization. The N-oxide thus obtained is then transferred by reduction into a corresponding compound of the general formula I.
Den påfølgende reduksjon av det oppnådde N-oksyd med formel I, overføres fortrinnsvis, i et oppløsningsmiddel som vann, vann/etanol, metanol, iseddik, eddiksyreetylester eller dimetylformamid, med hydrogen i nærvær av en hydreringskatalysator som Raney-nikkel, platina eller palladium/kull, med metaller som jern, tinn eller sink i nærvær av en syre som eddiksyre, saltsyre eller svovelsyre, med salter som jern(II)-sulfat, tinn(II)klorid eller natriumditionitt, eller med hydrazin i nærvær av Raney-nikkel, ved temperaturer mellom 0 og 50°C, men fortrinnsvis ved romtemperatur. The subsequent reduction of the obtained N-oxide of formula I is preferably carried out, in a solvent such as water, water/ethanol, methanol, glacial acetic acid, ethyl acetate or dimethylformamide, with hydrogen in the presence of a hydrogenation catalyst such as Raney nickel, platinum or palladium/ charcoal, with metals such as iron, tin or zinc in the presence of an acid such as acetic, hydrochloric or sulfuric acid, with salts such as iron(II) sulphate, tin(II) chloride or sodium dithionite, or with hydrazine in the presence of Raney nickel, at temperatures between 0 and 50°C, but preferably at room temperature.
b) Omsetning, av et benzimidazol med den generelle formel b) Reaction, of a benzimidazole with the general formula
hvor where
Rx til R3 er som innledningsvis definert, Rx to R3 are, as initially defined,
med en bifenylforbindelse med den generelle formel with a biphenyl compound of the general formula
hvor where
R4 er som innledningsvis definert og R4 is as initially defined and
Z3 utgjør en nukleofil utgående gruppe, så som et halogenatom, f.eks. et klor-, brom- eller jodatom, eller en substituert sulfonyloksygruppe, f.eks. en metansulfonyloksy-, fenyl-sulfonyloksy- eller p-toluensulfonyloksygruppe. Z 3 constitutes a nucleophilic leaving group, such as a halogen atom, e.g. a chlorine, bromine or iodine atom, or a substituted sulphonyloxy group, e.g. a methanesulfonyloxy, phenylsulfonyloxy or p-toluenesulfonyloxy group.
Omsetningen foretas hensiktsmessig i et oppløsningsmiddel eller en oppløsningsmiddelblanding som metylenklorid, dietyleter, tetrahydrofuran, dioksan, dimetylsulfoksyd, dimetylformamid eller benzen, eventuelt i nærvær av et syrebindende middel som natriumkarbonat, kaliumkarbonat, natriumhydroksyd, kalium-tert-butylat, natriumhydrid, trietylamin eller pyridin, hvorunder de to sistnevnte samtidig også kan benyttes som oppløsningsmiddel, fortrinnsvis ved temperaturer mellom 0 og 100°C, f.eks. ved temperaturer mellom romtemperatur og 50°C. The reaction is conveniently carried out in a solvent or a solvent mixture such as methylene chloride, diethyl ether, tetrahydrofuran, dioxane, dimethylsulfoxide, dimethylformamide or benzene, possibly in the presence of an acid binding agent such as sodium carbonate, potassium carbonate, sodium hydroxide, potassium tert-butylate, sodium hydride, triethylamine or pyridine, during which the latter two can simultaneously also be used as a solvent, preferably at temperatures between 0 and 100°C, e.g. at temperatures between room temperature and 50°C.
Ved omsetningen oppnår man fortrinnsvis en blanding av 1-og 3-isomerene- som deretter eventuelt kan spaltes i den tilsvarende 1- og 3-isomer ved kromatografi under bruk av et bærermateriale som kiselgel eller aluminiumoksyd. During the reaction, a mixture of the 1- and 3-isomers is preferably obtained, which can then possibly be resolved into the corresponding 1- and 3-isomer by chromatography using a carrier material such as silica gel or aluminum oxide.
c) For fremstilling av en forbindelse med den generelle formel I, hvor R4 utgjør en karboksygruppe: overføring av en forbindelse med den generelle formel c) For the preparation of a compound of the general formula I, where R4 constitutes a carboxy group: transfer of a compound of the general formula
hvor where
Rx til R3 er som innledningsvis definert, og Rx to R3 are as initially defined, and
R4 ' utgjør en gruppe som ved hydrolyse, termolyse eller hydrogenolyse kan overføres i en karboksygruppe. R 4 ' forms a group which, by hydrolysis, thermolysis or hydrogenolysis, can be transferred into a carboxy group.
Eksempelvis kan funksjonelle derivater av karboksygruppen i likhet med deres usubstituerte eller substituerte amider, estere, tiolestere, ortoestere, iminoetere, amidiner eller anhydrider, nitrilgruppen eller tetrazolylgruppen, ved hydrolyse overføres i en karboksygruppe, estere med tertiære alkoholer, f.eks. tert-butylester, ved termolyse overføres i en karboksygruppe og estere med aralkanoler, f.eks. benzyl-esteren, ved hydrogenolyse overføres i en karboksygruppe. For example, functional derivatives of the carboxyl group, like their unsubstituted or substituted amides, esters, thiol esters, orthoesters, iminoethers, amidines or anhydrides, the nitrile group or the tetrazolyl group, can by hydrolysis be transferred in a carboxyl group, esters with tertiary alcohols, e.g. tert-butyl ester, by thermolysis a carboxy group is transferred and esters with aralkanols, e.g. the benzyl ester, by hydrogenolysis is transferred in a carboxy group.
Hydrolysen utføres hensiktsmessig i nærvær av en syre som saltsyre, svovelsyre, fosforsyre, trikloreddiksyre eller trifluoreddiksyre, i nærvær av en base som natriumhydroksyd eller kaliumhydroksyd, i et egnet oppløsningsmiddel som vann, vann/metanol, etanol, vann/etanol, vann/isopropanol, vann/dioksan, metylenklorid eller kloroform ved temperaturer mellom -10°C og 120°C, f.eks. ved temperaturer mellom romtemperatur og reaksjonsblandingens kokepunkt. Ved hydrolyse i nærvær av en organisk syre som trikloreddiksyre eller trifluoreddiksyre, kan eventuelt forekommende alkoholiske hydroksygrupper samtidig overføres i en tilsvarende acyloksy-gruppe, som f.eks. trifluoracetoksygruppen. The hydrolysis is suitably carried out in the presence of an acid such as hydrochloric acid, sulfuric acid, phosphoric acid, trichloroacetic acid or trifluoroacetic acid, in the presence of a base such as sodium hydroxide or potassium hydroxide, in a suitable solvent such as water, water/methanol, ethanol, water/ethanol, water/isopropanol, water/dioxane, methylene chloride or chloroform at temperatures between -10°C and 120°C, e.g. at temperatures between room temperature and the boiling point of the reaction mixture. During hydrolysis in the presence of an organic acid such as trichloroacetic acid or trifluoroacetic acid, any alcoholic hydroxy groups that may occur can be simultaneously transferred into a corresponding acyloxy group, such as e.g. the trifluoroacetoxy group.
Betyr R4 ' i en forbindelse med den generelle formel V en cyano- eller aminokarbonylgruppe, kan disse gruppene også overføres i karboksygruppen med et nitritt, f.eks. natrium-nitritt, i nærvær av en syre som svovelsyre, som samtidig kan tjene som oppløsningsmiddel, ved temperaturer mellom 0 og 50°C. If R 4 ' in a compound of the general formula V is a cyano or aminocarbonyl group, these groups can also be transferred in the carboxy group with a nitrite, e.g. sodium nitrite, in the presence of an acid such as sulfuric acid, which can also serve as a solvent, at temperatures between 0 and 50°C.
Betyr R4 ' i en forbindelse med den generelle formel V for eksempel den tertiære butyloksykarbonylgruppe, kan den tertiære butylgruppen også avspaltes termisk, eventuelt i et egnet oppløsningsmiddel som metylenklorid, kloroform, benzen, toluen, tetrahydrofuran eller dioksan, og fortrinnsvis i nærvær av en katalytisk mengde av en syre som p-toluensulfonsyre, svovelsyre, fosforsyre eller polyfosforsyre, fortrinnsvis ved kokepunktet for det anvendte oppløsningsmiddel, f.eks. ved temperaturer mellom 40°C og 100°C. If R 4 ' in a compound of the general formula V is for example the tertiary butyloxycarbonyl group, the tertiary butyl group can also be cleaved off thermally, optionally in a suitable solvent such as methylene chloride, chloroform, benzene, toluene, tetrahydrofuran or dioxane, and preferably in the presence of a catalytic amount of an acid such as p-toluenesulfonic acid, sulfuric acid, phosphoric acid or polyphosphoric acid, preferably at the boiling point of the solvent used, e.g. at temperatures between 40°C and 100°C.
Betyr R4 ' i en forbindelse med den generelle formel V for eksempel benzyloksykarbonylgruppen, kan benzylgruppen også avspaltes hydrogenlytisk i nærvær av en hydreringskatalysator som palladium/kull, i et egnet oppløsningsmiddel som metanol, etanol, etanol/vann, iseddik, eddiksyreetylester, dioksan eller dimetylformamid, fortrinnsvis ved temperaturer mellom 0 og 50°C, f.eks. ved romtemperatur, og under et hydrogentrykk på 1 til 5 bar. Ved hydrogenolysen kan samtidig andre rester, f.eks. en nitrogruppe, med-reduseres til en aminogruppe, en benzyloksygruppe til en hydroksygruppe, en vinylidengruppe til en tilsvarende alkylidengruppe eller en kanelsyregruppe til en tilsvarende fenylpropionsyregruppe, eller erstattes med hydrogenatomer, f.eks. et halogenatom med et hydrogenatom. d) For fremstilling av en forbindelse med den generelle formel I, hvor R4 utgjør en lH-tetrazolylgruppe: avspaltning av en beskyttelsesrest fra en forbindelse med den generelle formel If R 4 ' in a compound of the general formula V for example the benzyloxycarbonyl group, the benzyl group can also be cleaved hydrogenolytically in the presence of a hydrogenation catalyst such as palladium/charcoal, in a suitable solvent such as methanol, ethanol, ethanol/water, glacial acetic acid, ethyl acetate, dioxane or dimethylformamide , preferably at temperatures between 0 and 50°C, e.g. at room temperature, and under a hydrogen pressure of 1 to 5 bar. During the hydrogenolysis, other residues, e.g. a nitro group, is co-reduced to an amino group, a benzyloxy group to a hydroxy group, a vinylidene group to a corresponding alkylidene group or a cinnamic acid group to a corresponding phenylpropionic acid group, or replaced by hydrogen atoms, e.g. a halogen atom with a hydrogen atom. d) For the preparation of a compound of the general formula I, where R 4 constitutes a 1H-tetrazolyl group: cleavage of a protecting residue from a compound of the general formula

Omsetningen skjer hensiktsmessig ved forestring med en tilsvarende alkohol eller med et tilsvarende reaktivt derivat, som f.eks. halogenidet, i et oppløsningsmiddel eller en opp-løsningsmiddelblanding som vann, metylenklorid, kloroform, eter, tetrahydrofuran, dioksan eller dimetylformamid, eller i et overskudd av acyleringsmidlet som oppløsningsmiddel, eventuelt i nærvær av et middel som virker aktiverende eller vanntiltrekkende på syren, så som tionylklorid, med deres anhydrider, estere eller halogenider, eventuelt i nærvær av en uorganisk eller tertiær organisk base som natriumhydroksyd, kaliumkarbonat, trietylamin eller pyridin, idet de to sistnevnte samtidig også kan tjene som oppløsningsmiddel, ved temperaturer mellom -25 og 100°C, fortrinnsvis ved temperaturer mellom -10 og 80°C. The reaction conveniently takes place by esterification with a corresponding alcohol or with a corresponding reactive derivative, such as e.g. the halide, in a solvent or a solvent mixture such as water, methylene chloride, chloroform, ether, tetrahydrofuran, dioxane or dimethylformamide, or in an excess of the acylating agent as a solvent, optionally in the presence of an agent which has an activating or water-attracting effect on the acid, such as thionyl chloride, with their anhydrides, esters or halides, optionally in the presence of an inorganic or tertiary organic base such as sodium hydroxide, potassium carbonate, triethylamine or pyridine, the latter two of which can simultaneously also serve as a solvent, at temperatures between -25 and 100°C, preferably at temperatures between -10 and 80°C.
I de ovenfor beskrevne omsetninger kan eventuelt forekommende reaktive grupper som hydroksy- eller iminogrupper, beskyttes under omsetningen ved hjelp av vanlige beskyttelsesgrupper som avspaltes igjen etter omsetningen. In the reactions described above, reactive groups that may occur, such as hydroxy or imino groups, can be protected during the reaction by means of common protective groups which are split off again after the reaction.
Aktuelle beskyttelsesrester for en hydroksygruppe er trimetylsilyl-, acetyl-, benzoyl-, metyl-, etyl-, tert-butyl-, benzyl- eller tetrahydropyranylgruppen, og for en iminogruppe, acetyl-, benzoyl-, etoksykarbonyl- eller benzylgruppen. Relevant protecting residues for a hydroxy group are the trimethylsilyl, acetyl, benzoyl, methyl, ethyl, tert-butyl, benzyl or tetrahydropyranyl group, and for an imino group, the acetyl, benzoyl, ethoxycarbonyl or benzyl group.
Den eventuelt påfølgende avspaltning av en benyttet beskyttelsesrest skjer fortrinnsvis hydrolytisk i et vandig oppløsningsmiddel, f.eks. i vann, isopropanol/vann, tetrahydrofuran /vann eller dioksari/vann, i nærvær av en syre, så som saltsyre eller svovelsyre, eller i nærvær av en alkalibase som natriumhydroksyd eller kaliumhydroksyd, ved temperaturer mellom 0 og 100°C, fortrinnsvis ved reaksjonsblandingens kokepunkt. Avspaltningen av en benzylrest skjer imidlertid fortrinnsvis hydrogenolytisk, f.eks. med hydrogen i nærvær av en katalysator som palladium/kull i et oppløsningsmiddel som under tilsetning av en syre, så som saltsyre, ved temperaturer mellom 0 og 50°C, men fortrinnsvis ved romtemperatur, og under et hydrogentrykk på 1 til 7 bar, fortrinnsvis på 3 til 5 bar. The possibly subsequent cleavage of a used protective residue preferably takes place hydrolytically in an aqueous solvent, e.g. in water, isopropanol/water, tetrahydrofuran/water or dioxarium/water, in the presence of an acid, such as hydrochloric acid or sulfuric acid, or in the presence of an alkali base such as sodium hydroxide or potassium hydroxide, at temperatures between 0 and 100°C, preferably at the reaction mixture's boiling point. However, the cleavage of a benzyl residue preferably takes place hydrogenolytically, e.g. with hydrogen in the presence of a catalyst such as palladium/charcoal in a solvent such as under the addition of an acid, such as hydrochloric acid, at temperatures between 0 and 50°C, but preferably at room temperature, and under a hydrogen pressure of 1 to 7 bar, preferably at 3 to 5 bar.
En således oppnådd isomerblanding av en forbindelse med den generelle formel I kan eventuelt spaltes, fortrinnsvis kromatografisk ved bruk av en bærer, så som kiselgel eller aluminiumoksyd. A thus obtained mixture of isomers of a compound of the general formula I can optionally be resolved, preferably chromatographically using a carrier, such as silica gel or aluminum oxide.
De oppnådde forbindelsene med den generelle formel I kan dessuten overføres i deres syreaddisjonssalter, spesielt for farmasøytisk anvendelse, i deres fysiologisk akseptable salter, med uorganiske eller organiske syrer. Som syrer for formålet kommer eksempelvis saltsyre, hydrogenbromidsyre, svovelsyre, fosforsyre, fumarsyre, ravsyre, melkesyre, sitronsyre, vinsyre eller maleinsyre i betraktning. The obtained compounds of the general formula I can also be transferred in their acid addition salts, especially for pharmaceutical use, in their physiologically acceptable salts, with inorganic or organic acids. Acids for this purpose include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.
Dessuten lar de således oppnådde nye forbindelser med den generelle formel I, dersom de inneholder en karboksy- eller IH-tetrazolylgruppe, seg deretter eventuelt overføre i deres salter med uorganiske eller organiske baser, spesielt for farmasøytisk anvendelse, i deres fysiologisk akseptable salter. Som baser kommer herunder eksempelvis natriumhydroksyd, kaliumhydroksyd, cyklogheksylamin, etanolamin, dietanolamin og trietanolamin i betraktning. Moreover, the thus obtained new compounds of the general formula I, if they contain a carboxy or IH-tetrazolyl group, can subsequently optionally be transferred into their salts with inorganic or organic bases, especially for pharmaceutical use, into their physiologically acceptable salts. Examples of bases include sodium hydroxide, potassium hydroxide, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.
De anvendte utgangsforbindelser med den generelle formel II til XIII er tildels kjent fra litteraturen eller kan oppnås ifølge fremgangsmåter kjent fra litteraturen. The starting compounds with the general formula II to XIII used are partly known from the literature or can be obtained according to methods known from the literature.
Således oppnås eksempelvis en forbindelse med den generelle formel II ved alkylering av en tilsvarende o-amino-acylamino-forbindelse med en forbindelse med den generelle formel IV. Den til formålet nødvendige o-aminoacylamino-forbindelse oppnås ved reduksjon av en tilsvarende o-nitro-acylamino-forbindelse, som på sin side oppnås ved nitrering av et tilsvarende acylaminoacetofenon, påfølgende overføring av det oppnådde, tilsvarende o-nitroacylaminoacetofenon i det tilsvarende 6-bromacetofenon, påfølgende cyklisering av w-bromacetofenonet med et tilsvarende syreamid og påfølgende reduksjon av nitrogruppen. Før reduksjonen av nitrogruppen kan en således oppnådd oksazol-4-yl-forbindelse ved hjelp av et tilsvarende amin, fortrinnsvis med ammoniakk, under trykk, overføres i den tilsvarende imidazol-4-yi-forbindelse, eller en således oppnådd i 1-stilling usubstituert imidazol-4-yl-forbindelse, ved alkylering overføres i en tilsvarende i 1-stilling alkylert imidazol-4-yl-forbindelse. Thus, for example, a compound of the general formula II is obtained by alkylating a corresponding o-amino-acylamino compound with a compound of the general formula IV. The o-aminoacylamino compound required for the purpose is obtained by reduction of a corresponding o-nitro-acylamino compound, which in turn is obtained by nitration of a corresponding acylaminoacetophenone, subsequent transfer of the obtained, corresponding o-nitroacylaminoacetophenone in the corresponding 6- bromoacetophenone, subsequent cyclization of the w-bromoacetophenone with a corresponding acid amide and subsequent reduction of the nitro group. Before the reduction of the nitro group, an oxazol-4-yl compound thus obtained can be transferred by means of a corresponding amine, preferably with ammonia, under pressure, into the corresponding imidazol-4-yl compound, or a thus obtained in the 1-position unsubstituted imidazol-4-yl compound, by alkylation is transferred into a corresponding imidazol-4-yl compound alkylated in the 1-position.
En utgangsforbindelse med den generelle formel III oppnås ved reduksjon og cyklisering av en av de foran beskrevne o-nitro-acylamino-forbindelser. A starting compound with the general formula III is obtained by reduction and cyclization of one of the o-nitro-acylamino compounds described above.
En utgangsforbindelse med den generelle formel V, VI, VII og VIII oppnås ved omsetning av en forbindelse med den generelle formel III med en tilsvarende forbindelse med den generelle formel IV. A starting compound of the general formula V, VI, VII and VIII is obtained by reacting a compound of the general formula III with a corresponding compound of the general formula IV.

The final pellet is resuspended in incubation buffer (50 mmol Tris, 5 mmol MgCl2, 0.2% BSA, pH 7.40) 1:75, calculated on the basis of the weight of the moist tissue. Portions of 0.1 mL homogenate are incubated for 60 min. at 37°C with 50 pM [<125>I]-angiotensin II (NEN, Dreieich, Germany) and increasing concentrations of the test compound in a total volume of 0.25 mL. The incubation is terminated by rapid filtration through a glass fiber filter mat. The filters are washed with 4 mL ice-cold buffer (25 mmol Tris, 2.5 mmol MgCl2, 0.1% BSA, pH 7.40).

Dosen for disse virkestoffene utgjør herunder hensiktsmessig 1/5 av den ellers anbefalte laveste dosering opp til l/l av den vanligvis anbefalte dosering, hvilket vil si for eksempel 15 til 200 mg hydroklortiazid, 125 til 2000 mg klortiazid, 15 til 200 mg etakrynsyre, 5 til 80 mg furosemid, 20 til 480 mg propranolol, 5 til 60 mg felodipin, 5 til 60 mg nifedipin eller 5 til 60 mg nitrendipin. The above-mentioned combinations may thus further include active substances, such as bendroflumethiazide, chlorothiazide, hydrochlorothiazide, spironolactdn, benzthiazide, cyclothiazide, ethacrynic acid, furosemide, metoprolol, prazosin, atenolol, propranolol (di)hydralazine hydrochloride, diltiazem, felodipine, nicardipine, nifedipine , nisoldipine, nitrendipine, captopril, enalapril, lisinopril, cilazapril, quinapril, fosinopril and ramipril. The dose for these active substances is appropriately 1/5 of the otherwise recommended lowest dosage up to l/l of the usually recommended dosage, which means for example 15 to 200 mg hydrochlorothiazide, 125 to 2000 mg chlorothiazide, 15 to 200 mg ethacrynic acid, 5 to 80 mg furosemide, 20 to 480 mg propranolol, 5 to 60 mg felodipine, 5 to 60 mg nifedipine, or 5 to 60 mg nitrendipine.
