Under cykloalkyl forstås også alkylsubstituerte rester, som f.eks. 4-metylcykloheksyl eller 2,3-dimetylcyklopentyl. Cycloalkyl also means alkyl-substituted residues, such as e.g. 4-methylcyclohexyl or 2,3-dimethylcyclopentyl.

Under salter av forbindelsene med formel I forstås spesielt farmasøytisk anvendbare eller ikke-toksiske salter. By salts of the compounds of formula I is meant particularly pharmaceutically usable or non-toxic salts.

Slike salter blir eksempelvis dannet fra forbindelser med formel I, som inneholder sure grupper, f.eks. karboksy, med alkali- eller jordalkalimetaller, som Na, K, Mg og Ca, samt med fysiologisk tålbare organiske aminer, som f.eks. trietylamin og tri-(2-hydroksy-etyl)-amin.

Metoder som er egnede for fremstilling av en amidbinding er f.eks. beskrevet i Houben-Weyl, Methoden der organischen Chemie, bind 15/2; Bodanszky et al., Peptide synthesis, 2. utg. (Wiley & Sons, New York 1976) eller Gross, Meienhofer, The Peptides. Analysis, synthesis, biology (Academic Press, New York 1979). Følgende fremgangsmåte blir fortrinnsvis anvendt: Aktivestermetode med N-hydroksy-succinimid som esterkomponenter, kobling med et karbodiimid som dicykloheksylkarbodiimid eller med propanfosfonsyreanhydrid og blandet-anhydrid-metoden med pivaloylklorid. Methods that are suitable for producing an amide bond are e.g. described in Houben-Weyl, Methoden der organischen Chemie, volume 15/2; Bodanszky et al., Peptide synthesis, 2nd ed. (Wiley & Sons, New York 1976) or Gross, Meienhofer, The Peptides. Analysis, synthesis, biology (Academic Press, New York 1979). The following method is preferably used: active ester method with N-hydroxysuccinimide as ester components, coupling with a carbodiimide such as dicyclohexylcarbodiimide or with propanephosphonic anhydride and the mixed-anhydride method with pivaloyl chloride.

Fremstilling av de anvendte optisk aktive aminodiolene med formel V anvendt som utgangsforbindelse Preparation of the used optically active aminodiols of formula V used as starting compound

kan eksempelvis i det tilfellet hvor n er 2 foregå ved omsetning av en forbindelse med formel VI med en forbindelse med formel VII etter deprotoneringen derav. can, for example, in the case where n is 2 take place by reaction of a compound of formula VI with a compound of formula VII after its deprotonation.

I formel VI betyr P^ en uretanbeskyttelsesgruppe, fortrinnsvis N-tert.-butoksykarbonyl- og benzyloksykarbonyl. In formula VI, P₁ means a urethane protecting group, preferably N-tert-butoxycarbonyl and benzyloxycarbonyl.

Som baser for deprotonering av heteroarylalkylkomponenten kan alkalimetallalkoholater, som kalium-O-tert.-butylat, natriummetylat, alkalimetallhydrider, som natrium- eller kaliumhydrid, metallorganiske baser, som n-butyllitium, s-butyllitium, metyllitium eller fenyllitium, natriumamid samt alkalimetallsalter av organiske nitrogenbaser, som litiiim-diisopropylamid anvendes. As bases for deprotonation of the heteroarylalkyl component, alkali metal alcoholates, such as potassium O-tert.-butylate, sodium methylate, alkali metal hydrides, such as sodium or potassium hydride, organometallic bases, such as n-butyllithium, s-butyllithium, methyllithium or phenyllithium, sodium amide and alkali metal salts of organic nitrogen bases such as lithium diisopropylamide are used.

Addisjon av forbindelsene med formel VII på de nevnte N-beskyttede epoksydene foregår i et overfor basen inert oppløsningsmiddel som eter, THF, toluen, DMF,. DMSO eller dimetoksyetan. Addition of the compounds of formula VII to the aforementioned N-protected epoxides takes place in a base-inert solvent such as ether, THF, toluene, DMF. DMSO or dimethoxyethane.

Forbindelser med formel VI er kjent fra EP-A 189 203. Compounds of formula VI are known from EP-A 189 203.

Videre kan de forskjellige isomerene av forbindelser med formel V bli fremstilt ifølge skjema 1 vist nedenfor: Furthermore, the various isomers of compounds of formula V can be prepared according to scheme 1 shown below:

Dersom den valgte synteseveien fører til diastereomerer med hensyn på OR^ Qg or^ bærende sentrene, kan disse separeres på i seg selv kjent måte, eksempelvis ved fraksjonert krystallisasjon eller ved kromatografi. Overprøving av diastereomer-renheten foregår ved hjelp av HPLC og enantiomerrenheten kan overprøves på kjent måte ved overprøving i Mosher-derivater (H. S. Mosher et al., J. Org. Chem. 34, 2543 (1969)). If the chosen synthesis route leads to diastereomers with regard to the OR^ Qg or^ bearing centers, these can be separated in a manner known per se, for example by fractional crystallization or by chromatography. Testing of the diastereomeric purity takes place by means of HPLC and the enantiomeric purity can be tested in a known manner by testing in Mosher derivatives (H. S. Mosher et al., J. Org. Chem. 34, 2543 (1969)).

I en oppnåelig forbindelse med formel I kan man oksidere en tiogruppe til en sulfinyl- eller sulfonylgruppe eller en sulfinylgruppe til en sulfonylgruppe. In an obtainable compound of formula I, a thio group can be oxidized to a sulfinyl or sulfonyl group or a sulfinyl group to a sulfonyl group.

Oksidasjonen til sulfonylgruppen kan bli gjennomført ved hjelp av de fleste vanlige oksidasjonsmidlene. Man anvender fortrinnsvis slike oksidasjonsmidler som oksiderer tiogruppen eller sulfinylgruppen selektivt i nærvær av andre funksjonelle grupper av forbindelsen med formel I, f.eks. amid-funksjonen og hydroksygruppen, eksempelvis aromatiske eller alifatiske peroksykarboksylsyrer, f.eks. perbenzosyre, monoperftalsyre, m-klorperbenzosyre, pereddiksyre, permaur-syre eller trifluorpereddiksyre. The oxidation to the sulfonyl group can be carried out using most common oxidizing agents. Such oxidizing agents are preferably used which oxidize the thio group or the sulfinyl group selectively in the presence of other functional groups of the compound of formula I, e.g. the amide function and the hydroxy group, for example aromatic or aliphatic peroxycarboxylic acids, e.g. perbenzoic acid, monoperphthalic acid, m-chloroperbenzoic acid, peracetic acid, permauric acid or trifluoroperacetic acid.

De for fremstilling av forbindelser med formel I nødvendige for- og etteroperasjoner som innføring og avspaltning av beskyttelsesgrupper er kjent i litteraturen og er f.eks. beskrevet i T.W. Greene, "protective Groups in Organic Synthesis". Salter av forbindelser med formel I med salt-dannende grupper blir fremstilt på kjent måte, idet man f.eks. omsetter en forbindelse med formel I med en basis-gruppe med en støkiometrisk mengde av en egnet syre. Stereoisomerblandinger, spesielt diastereomerblandinger, som oppstår ved anvendelse av de rasemiske syrene A eller B kan på kjent måte bli separert ved fraksjonert krystallisasjon eller ved kromatografi. The pre- and post-operations necessary for the preparation of compounds of formula I, such as the introduction and removal of protective groups, are known in the literature and are e.g. described in T.W. Greene, "Protective Groups in Organic Synthesis". Salts of compounds of formula I with salt-forming groups are prepared in a known manner, e.g. reacts a compound of formula I with a base group with a stoichiometric amount of a suitable acid. Mixtures of stereoisomers, in particular mixtures of diastereomers, which occur when the racemic acids A or B are used can be separated in a known manner by fractional crystallization or by chromatography.

Forbindelsene med formel I fremstilt ifølge oppfinnelsen viser enzymhemmende egenskaper; de hemmer spesielt virkningen av det naturlige enzymet renin. Renin er et protolyttisk enzym fra aspartyl-proteaseklassen som på grunn av forskjellige stimuli (volumdeplesjon, natriummangel, p-reseptor-stimulering) av de jukstaglomulære cellene til nyrene blir sezernert i blodomløpet. Dette blir gjennom "angiotensin-omdannende enzym" (ACE) overført til Angiotensin II. Angiotensin II spiller en vesentlig rolle ved blodtrykks-regulering da det direkte øker blodtrykket ved vene-kontraksjon. Det stimulerer først utskillingen av aldosteron fra binyrene og forhøyer på denne måten over hemmingen av natrium-utskillingen det ekstracellulære væskevolumet, som innebærer en stigning av blodtrykket. Hemming av den enzymatiske aktiviteten av renin fører til en mindre dannelse av Angiotensin I som medfører en forminsket dannelse av Angiotensin II. Senkingen av konsentrasjonen av dette aktive peptidhormonet er en direkte årsak for den blodtrykkssenkende virkningen av renin-hemmere. The compounds of formula I prepared according to the invention show enzyme-inhibiting properties; they specifically inhibit the action of the natural enzyme renin. Renin is a protolytic enzyme from the aspartyl protease class which, due to various stimuli (volume depletion, sodium deficiency, p-receptor stimulation) by the juxtaglomular cells of the kidneys is secreted into the bloodstream. This is transferred through "angiotensin-converting enzyme" (ACE) to Angiotensin II. Angiotensin II plays an important role in blood pressure regulation as it directly increases blood pressure during vein contraction. It first stimulates the secretion of aldosterone from the adrenal glands and in this way, over the inhibition of sodium excretion, increases the extracellular fluid volume, which entails a rise in blood pressure. Inhibition of the enzymatic activity of renin leads to a smaller formation of Angiotensin I which leads to a reduced formation of Angiotensin II. The lowering of the concentration of this active peptide hormone is a direct cause of the blood pressure-lowering effect of renin inhibitors.

Virkningen av renin-hemmere kan overprøves ved in-vitro-tester. Her blir forminskningen av dannelse av Angiotensin I målt i forskjellige systemer (humanplasma, svine-renin). Her blir f.eks. humanplasma, som både inneholder renin og angiotensinogen, inkubert ved 37° C med forbindelsen som skal testes. Til slutt blir konsentrasjonen av de i løpet av inkubasjonen dannede Angiotensin I målt med en radio-immunoanalyse. De i foreliggende oppfinnelse beskrevne forbindelser med generell formel I viser i anvendte in-vitro-tester hemmevirkninger ved konsentrasjoner på omtrent IO"<5> til 10_10 mol/l. The effect of renin inhibitors can be verified by in vitro tests. Here, the reduction in the formation of Angiotensin I is measured in different systems (human plasma, pig renin). Here, e.g. human plasma, containing both renin and angiotensinogen, incubated at 37°C with the compound to be tested. Finally, the concentration of the Angiotensin I formed during the incubation is measured with a radio-immunoassay. The compounds of general formula I described in the present invention show inhibitory effects in applied in vitro tests at concentrations of approximately 10"<5> to 10_10 mol/l.

Renin-hemmere fører til senkning av blodtrykket i dyr som er utarmet på salt. På grunn av at menneskelig renin er forskjellig fra renin i andre arter blir primater anvendt for in-vivo-test av renin-hemmerene (marmosets, rhesus-aper). Primat-renin og human-renin har stort sett homologe sek-venser. Ved i. v. injeksjon av furosemid blir en endogen renin-utskilling stimulert. Til slutt blir testforbindelsene gjennom kontinuerlig infusjon gjennom engangsintravenøse bolusdoser, gjennom intraduodenale eller gjennom perorale doser administrert og deres virkning på blodtrykket og hjertefrekvensen blir målt. Forbindelsene fremstilt ifølge foreliggende oppfinnelse er herved virksomme i et doserings-område på omtrent 0,1-5 mg/kg i. v. henholdsvis 1-50 mg/kg i.d. eller p.o. De i foreliggende oppfinnelse beskrevne forbindelsene med generell formel I kan anvendes som antihypertensive midler samt for behandling av hjerte-insuffisiens. Renin inhibitors lead to lowering of blood pressure in salt-depleted animals. Because human renin is different from renin in other species, primates are used for in-vivo testing of the renin inhibitors (marmosets, rhesus monkeys). Primate renin and human renin have largely homologous sequences. When furosemide is injected i.v., endogenous renin secretion is stimulated. Finally, the test compounds are administered by continuous infusion through single intravenous bolus doses, through intraduodenal or through oral doses and their effect on blood pressure and heart rate is measured. The compounds produced according to the present invention are thereby effective in a dosage range of approximately 0.1-5 mg/kg i.v., respectively 1-50 mg/kg i.d. or p.o. The compounds of general formula I described in the present invention can be used as antihypertensive agents as well as for the treatment of heart insufficiency.

Farmasøytiske preparater inneholder en virksom mengde av det virksomme stoffet med formel I sammen med et uorganisk eller organisk farmasøytisk anvendbart bærerstoff. Anvendingen kan foregå intranasalt, intravenøst, subkutant eller peroralt. Doseringen av det virksomme stoffet avhenger av den varmblo-dige arten, kroppsvekten, alderen og av applikasjonsmåten. Pharmaceutical preparations contain an effective amount of the active substance of formula I together with an inorganic or organic pharmaceutically usable carrier substance. The application can take place intranasally, intravenously, subcutaneously or orally. The dosage of the active substance depends on the warm-blooded species, body weight, age and the method of application.

For en oral anvendelsesform blir de aktive forbindelsene blandet med de dertil egnede tilsetningsstoffene som bærerstoffer, stabilisatorer eller inerte fortynningsmidler og brakt ifølge vanlige metoder til egnede administrerings-former, som tabletter drageer, stikkapsler, vandige, alkoholiske eller oljeholdige suspensjoner eller vandige, alkoholiske eller oljeholdige oppløsninger. Som Inert bærer kan f.eks. gummi arabikum, magensia, magnesiumkarbonat, kaliumfosfat, melkesukker, glukose, magnesiumstearylfumarat eller stivelse, spesielt maisstivelse anvendes. Tilberednin-gen kan foregå både som tørr- og fuktgranulat. Som oljeholdige bærerstoffer eller oppløsningsmidler kommer oljer fra planter eller dyr i betraktning, som solsikkeolje eller levertran.
