Description
Foreliggende oppfinnelse angår nye karboksylsyrederivater.
Endotelin er et peptid sammensatt av 21 aminosyrer og blir syntetisert og frigjort fra vaskulært endotel. Endotelin eksisterer i tre isoformer, ET-1, ET-2 og ET-3. "Endotelin" eller "ET" omfatter i det følgende én eller alle isoformer av endotelin. Endotelin er en kraftig vasokonstriktor og har en sterk virkning på vaskulær tonus. Det er kjent at denne vasokonstriksjon forårsakes av binding av endotelin til sin reseptor (Nature, 332, 411-415,1988; FEBS Letters, 231, 440-444,1988 og Biochem. Biophys. Res. Commun., 154. 868-875,1988).
Forhøyet eller unormal frigjøring av endotelin forårsaker vedvarende vasokonstriksjon i perifere, renale og cerebrale blodkar, hvilket kan føre til sykdom. Som angitt i litteraturen, er forhøyede nivåer av endotelin i plasma funnet hos pasienter med hypertensjon, akutt myokardialt infarkt, pulmonal hypertensjon, Raynauds syndrom, aterosklerose og i luftveiene hos astmatikere (Japan J. Hypertension, 12, 79 (1989), J. Vascular Med. Biology 2, 207 (1990), J. Am. Med. Association 264, 2868 (1990)).
Forbindelser som spesifikt hemmer binding av endotelin til reseptoren skulle følgelig også antagonisere de forskjellige ovennevnte fysiologiske virkninger av endotelin og derfor være verdifulle medikamenter.
Det er allerede funnet (WO 94/02474) at visse karboksylsyrederivater med den generelle formel Q er gode inhibitorer av endotelin-reseptorer
Dette gjelder imidlertid hovedsakelig forbindelser med en dobbelt-binding i molekylet. I tillegg til RA og R<B> maksimalt ett hydrogenatom tillatt på p-senteret.
Det er nå overraskende funnet at dette hydrogenatomet kan erstattes med alkyl-rester. Dette resulterer i et kvaternært p-senter med samtidig stor økning av aktiviteten når det gjelder endotelin-reseptorer (se eksemplene).
Oppfinnelsen angår karboksylsyre-derivater med formel I
hvor R<1> er COOH og de andre substituentene har de følgende betydninger:
R<2> og R3 (som kan være like eller forskjellige):
fenyl eller naftyl, som kan være substituert med én eller flere av de følgende rester Ci-C^alkyl, og Ci-C4-alkoksy,
R<4>: fenyl eller naftyl, metylendioksyfenyl eller etylendioksyfenyl som kan være substituert med én eller flere av de følgende rester: hydroksy, Ci-C4-alkyl, Ci-C4-alkoksy, benzyloksy,
R<5>: d-Cs-alkyl,
n: 1-2.
Forbindelsene og mellomprodukter for fremstilling av dem, som f.eks. Va, kan ha ett eller flere asymmetrisk substituerte karbonatomer. Slike forbindelser kan være i form av rene enantiomerer eller rene diastereomerer, eller en blanding derav. Anvendelse av en enantiomert ren forbindelse som virkestoff er foretrukket.
Videre beskrives anvendelse av ovennevnte karboksylsyrederivater for fremstilling av medikamenter, spesielt for produksjon av inhibitorer for endotelin-reseptorer.
Forbindelser med formel I kan fremstilles ved først å omsette et keton av type II med en fosfonoester med formel III i nærvær av en base, hvilket gir forbindelsene med formel IV.
Aprotiske, polare oppløsningsmidler så som DMF eller THF anvendes som oppløsningsmidler.
Som base kan anvendes et alkali- eller jordalkalimetallhydrid så som natriumhydrid, kaliumhydrid eller kalsiumhydrid, et karbonat så som alkalimetallkarbonat, f.eks. natrium- eller kaliumkarbonat, et alkali- eller jordalkalimetallhydroksyd så som natrium- eller kaliumhydroksyd, en metallorganisk forbindelse så som butyllitium, et alkalimetallalkoholat så som natriumetanolat eller kalium-tert-butanolat eller et alkalimetallamid så som litiumdiisopropylamid.
Reaksjonen blir fortrinnsvis utført ved en temperatur i området mellom 0°C og kokepunktet til oppløsningsmidlet eller oppløsningsmiddel-blandingen.
Forbindelsene av type IV kan deretter omsettes med aromatiske forbindelser i nærvær av en katalysator, hvilket gir karboksylsyre-derivatene med den generelle formel Va.
Egnede katalysatorer for dette er sterke, uorganiske syrer og Lewis-syrer. Eksempler på slike er bl.a. svovelsyre, aluminiumtriklorid, sinkklorid eller jerntriklorid. Når svovelsyre anvendes, kan den frie syren oppnås direkte.
Alternativt kan symmetriske karboksylsyrederivater med formel Vb fremstilles fra en p-dikarbonylforbindelse VI og en aromatisk forbindelse i nærvær av en katalysator.
Egnede katalysatorer for dette er sterke, uorganiske syrer samt Lewis syrer. Eksempler på disse er bl.a. svovelsyre, aluminiumtriklorid, sinkklorid eller jerntriklorid (se også: Gogte G.R. et al., J. Univ. Bombay, Sect. A, 27, 1958, 41).
En annen mulighet for fremstilling av forbindelser av typen Va kan være å starte fra et keton VII
som kan omsettes med Meldrums syre i nærvær av en base så som pyridin eller natriumhydrid, hvilket gir forbindelser av typen VIII. Omsetning av forbindelser av type VIII i dietyleter med et Grignard-reagens med den generelle formel IX resulterer i forbindelser av type X,
i hvilket tilfelle det kan være fordelaktig i tillegg å anvende kobbersalter så som kobberklorid, kobberbromid, kobberjodid ellerkobbercyanid og aten Lewis-syre så som trimetylsilylklorid eller bortrifluorideterat er til stede.
Hydrolyse av forbindelser med formel X med mineralsyrer så som saltsyre eller svovelsyre kan deretter gi forbindelsene Va (R = OH).
Ytterligere muligheter for fremstilling av forbindelsene Va kan være analogt med metoden til Zimmermann H.E. et al. J. Am. Chem, Soc. 83,1961, 1196 eller Yu A.J. et al. J. Org. Chem. 23,1958,1004.
Forbindelser med formel Va,b kan ved -78°C til romtemperatur, omdannes til anionet (eller dianionet for R=H) med en sterk base som f.eks. butyllitium eller litiumdiisopropylamid i et inert oppløsningsmiddel som f.eks. dietyleter eller tetrahydrofuran og under en inert gass som f.eks. nitrogen eller argon. Dette anionet reagerer med alkyleringsmidler av type VII ved -78°C til romtemperatur. Behandling med konsentrert NH4CI eller fortynnet mineralsyre så som HCI, resulterer i forbindelsene med formel I.
Forbindelser av type I hvor R<1> = tetrazol kan syntetiseres ved å starte fra karboksylsyrer I (R<1> = COOH). For dette blir karboksylsyren omsatt med tionylklorid ved romtemperatur, hvilket gir syrekloridet, som deretter omsettes med en vandig ammoniakk-oppløsning for å gi amidet med formel XII
Amider med formel XII kan omsettes med oksalylklorid eller fosforoksyklorid eller trifluoreddiksyreanhydrid i DMF eller pyridin ved 0°C til romtemperatur, hvilket gir nitriler med formel XIII Omsetning av nitrilene med formel XIII med natriumazid eller trimetylsilylazid i et egnet oppløsningsmiddel så som dimetylformamid, tetrahydrofuran eller 1-metyl-2-pyrrolidinon, i nærvær av en katalysator så som ammoniumklorid (se også: Bernsteim P.R. et al., Synthesis, 1987,1133) ved romtemperatur eller forhøyet temperatur, gir tetrazolet XIV
Forbindelser med formel I kan også fremstilles ved å starte fra de tilsvarende karboksylsyrene, dvs. forbindelser med formel I hvor R<1> = COOH, og omdanne disse først på konvensjonell måte til en aktivert form så som et syrehalogenid, -anhydrid eller -imidazolid, og deretter omsette sistnevnte med en passende hydroksyl-forbindelse HOR. Denne reaksjonen kan utføres i konvensjonelle oppløsningsmidler, og krever ofte tilsetning av en base, i hvilket tilfelle de som er angitt ovenfor, er egnet. Disse to trinn kan også forenkles, f.eks. ved at karboksylsyren får virke på hydroksyl-forbindelsen i nærvær av et dehydratiseringsmiddel så som karbodiimid.
Forbindelser med formel I kan også fremstilles ved å starte fra salter av de tilsvarende karboksylsyrer, dvs. fra forbindelser med formel I hvor R<1> er COR og R er OM, hvor M kan være et alkalimetall-kation eller ekvivalenten av et jordalkalimetall-kation. Disse saltene kan omsettes med mange forbindelser med formelen R-A hvor A er en konvensjonell nukleofug utgående gruppe, f.eks. halogen så som klor, brom, jod eller aryl- eller alkylsulfonyl som er usubstituert eller substituert med halogen, alkyl eller halogenalkyl, så som toluensulfonyl og metylsulfonyl, eller en annen ekvivalent utgående gruppe. Forbindelser med formelen R-A med en reaktiv substituent A er kjente eller kan lett oppnås med generell fagkunnskap. Denne reaksjonen kan utføres i vanlige oppløsningsmidler, og utføres fordelaktig ved tilsetning av en base, i hvilket tilfelle de som er angitt ovenfor er egnet.
Enantiomert rene forbindelser med formel I kan oppnås ved å utføre, med racemiske eller diastereomere forbindelser med formel VI, en klassisk racemat-spaltning med egnede enantiomert rene baser, så som brucin, stryknin, kinin, kinidin, cinkonidin, cinkonin, yohimbin, morfin, dehydroabietylamin, efedrin (-), (+), deoksyefedrin (-), (+), treo-2-amino-1-(p-nitrofenyl)-1,3-propandiol (-), (+), treo-2-(N,N-dimetylamino)-1-(p-nitrofenyl)-1,3-propandiol (+), (-), treo-2-amino-1-fenyl-1,3-propandiol (+), (-), a-metylbenzylamin (+), (-), a-(1-naftyl)etylamin (+),
(-), a-(2-naftyl)etylamin (+), (-), aminometylpinan, N,N-dimetyl-1-fenyletylamin, N-metyl-1-fenyletylamin, 4-nitrofenyletylamin, pseudoefedrin, norefedrin, norpseudoefedrin, aminosyrederivater og peptidderivater. Mange variasjoner er mulige for resten R<1> i formel I. F.eks. er R<1> en gruppe

Den gode virkningen til forbindelsene kan vises i de følgende forsøkene:
Reseptorbindingsstudier
Klonede humane ETA-reseptor-uttrykkende CHO-celler og membraner med > 60 % ETs-reseptorer fra marsvin-cerebellum sammenlignet med ETa-reseptorene ble anvendt for bindingsstudier.
Membran- preparering
De ETA-reseptor-uttrykkende CHO-cellene ble dyrket i Fi2-medium med 10 % føtalt kalveserum, 1 % glutamin, 100 U/ml penicillin og 0,2 % streptomycin (Gibco BRL, Gaithersburg, MD, USA). Etter 48 timer ble cellene vasket med PBS og inkubert med 0,05 % trypsin-inneholdende PBS i 5 min. Deretter ble nøytralisering utført med Fi2-medium, og cellene ble oppsamlet ved sentrifugering ved 300 x g. For lysing av cellene ble pelleten vasket kort med lyse-buffer (5 mM tris-HCI, pH 7,4 med 10 % glycerol) og deretter inkubert i en konsentrasjon på 10<7 >celler/ml lysebuffer i 30 min ved 4°C . Membranene ble sentrifugert ved 20.000 x g i 10 minutter, og pelleten ble lagret i flytende nitrogen.
Marsvin-lillehjerne ble homogenisert i Potter-Elvejhem-homogenisator og gjenvunnet ved differensiell sentrifugering ved 1000 x g i 10 minutter og gjentatt sentrifugering av den overliggende væsken ved 20.000 x g i 10 minutter.
Bindingsforsøk
For ETA- og ETB-reseptorbindingsforsøket ble membranene suspendert i en inkuberings-buffer (50 mM tris-HCI, pH 7,4), med 5 mM MnCI2, 40 jig/ml bacitracin og 0,2 % BSA) i en konsentrasjon på 50 ug protein pr. forsøksblanding og inkubert i nærvær og fravær av test-forbindelse med 25 pM <125>l-ETi (ETa-reseptortest) eller 25 pM <125->RZ3 (ETB-reseptortest) ved 25°C. Den ikke-spesifikke binding ble bestemt med 10"<7> M ETi. Etter 30 min. ble den frie og den bundne radioligand separert ved filtrering gjennom GF/B-glassfiber-filtere (Whatman, England) på en Skatron-celleoppsamler (Skatron, Lier, Norge), og filtrene ble vasket med iskald tris-HCI-buffer, pH 7,4 med 0,2% BSA. Radioaktiviteten som var oppsamlet på filtrene ble kvantifisert ved anvendelse av en Packard 2200 CA flytende scintillasjons-teller.
Funksjonelt in vitro testsystem for undersøkelse av endotelin- reseptor- ( undertvpe A) antagonister
Dette testsystemet er en funksjonell, celle-basert test på endotelin-reseptorer. Visse celler viser, når de blir stimulert med endotelin 1 (ET1), en - økning i den intracellulære kalsium-konsentrasjonen. Denne økning kan måles på intakte celler som er lastet med kalsium-sensitive farvestoffer.
1-fibroblaster som var isolert fra rotter og i hvilke en endogen endotelin-reseptor av A-undertypen var detektert, ble lastet med fluorescerende farvestoff Fura 2-an som følger: Etter trypsinering ble cellene resuspendert i buffer A (120 mM NaCI, 5 mM KCI, 1,5 mM MgCI2, 1 mM CaCI2, 25 mM HEPES, 10 mM glukose, pH 7,4) til en densitet på 2 x 10<6>/ml, og inkubert med Fura-2-am (2 |j.M), Pluronic F-127 (0,04 %) og DMSO (0,2 %) ved 37°C i mørket i 30 minutter. Deretter ble cellene vasket to ganger med buffer A og resuspendert med 2 x
10<6>/ml.
Fluorescens-signalet fra 2 x 105 celler pr. ml med Ex/Em 380/510 ble nedtegnet kontinuerlig ved 30°C. Test-forbindelsene og, etter en inkuberingstid på 3 min., ET1 ble satt til cellene. Maksimums-endring i fluorescensen ble bestemt over 30 min. Responsen til cellene på ET1 uten forutgående tilsetning av en test-forbindelse tjente som kontroll og ble satt til 100%.
In vivo testing av ET- antaqonister
SD-hannrotter som veidde 250 - 300 g, ble bedøvet med amobarbital, kunstig ventilert, vagotomisert og ryggmarg ble fjernet. Karotid-arterien og jugular-venen ble kateterisert.
Intravenøs administrering av 1 ug/kg ET1 til kontrolldyrene, fører til en distinkt økning i blodtrykk, som vedvarer i en lengere periode. Test-forbindelsene ble injisert i.v. (1 ml/kg) i test-dyrene 5 eller 30 min. før ET1-administrering. For å bestemme ET-antagonist-egenskapene, ble økning av blodtrykket hos test-dyrene sammenlignet med det til kontrolldyrene.
Endotelin- 1- fremkalt plutselig død hos mus
Prinsippet i testen omfatter hindring av plutselig død hos mus som er forårsaket av endotelin, som sannsynligvis skyldes konstriksjon av koronar-kar, ved forhåndsbehandling med endotelin-reseptor-antagonister. Intravenøs injeksjon av 10 nmol/kg endotelin i et volum på 5 ml/kg legemsvekt resulterer i at dyrene dør innen få minutter.
Den dødelige endotelin-1-dose blir undersøkt i hvert tilfelle på en liten gruppe dyr. Hvis test-forbindelsen blir administrert intravenøst, blir den vanligvis fulgt etter 5 min. med endotelin-1-injeksjonen som var dødelig for referanse-gruppen. Ved andre administreringsmetoder er tiden før administrering lenger, når det passer, opptil flere timer.
Overlevelsesgraden blir nedtegnet, og effektive doser som beskytter 50% av dyrene 24 timer eller mer mot endotelin-fremkalt hjertedød (ED 50) blir bestemt.
Funksjonell test på endotelin- reseptor- antagonister på kar
Segmenter av kanin-aorta med en opprinnelig spenning på 2 g og relaksasjonstid på 1 time i Krebs-Henseleit-oppløsning ved 37°C og en pH-verdi mellom 7,3 og 7,4 blir først sammentrukket med K<+>. Etter utvasking blir et endotelin-dose-effekt-plott konstruert opp til maksimum.
Potensielle endotelin-antagonister blir administrert til andre preparater av samme kar 15 min. før begynnelsen av endotelin-dose-effekt-plottet. Virkningene av endotelin blir beregnet som % av K<+->kontraksjonen. Effektive endotelin-antagonister resulterer i en forskyvning av endotelin-dose-effekt-plottet til høyre.
Forbindelsene ifølge oppfinnelsen kan administreres oralt eller parenteralt (subkutant, intravenøst, intramuskulært, intraperitonealt) på vanlig måte. Administrering kan også utføres med damp eller spray gjennom nasofaryngeal-rommet.
Doseringen er avhengig av alder, tilstand og vekt til pasienten og administreringsmetoden. Vanligvis er den daglige dose av midlet ca. 0,5-50 mg/kg kroppsvekt ved oral administrering og ca. 0,1-10 mg/kg kroppsvekt ved parenteral administrering.
De nye forbindelsene kan anvendes i konvensjonelle faste eller flytende farmasøytiske former, f.eks. som ubelagte eller (film-) belagte tabletter, kapsler, pulvere, granuler, suppositorier, oppløsninger, salver, kremer eller spray-preparater. Disse fremstilles ved konvensjonelle metoder. Midlene kan for dette formål fremstilles med konvensjonelle farmasøytiske hjelpestoffer, så som tablett-bindemidler, svellemidler, konserveringsmidler, tablett-desintegreringsmidler, strømningsregulatorer, mykningsmidler, fuktemidler, dispergeringsmidler, emulgeringsmidler, oppløsningsmidler, frigjørings-forsinkende midler, antioksydanter og/eller drivgasser (cf. H. Sucker et al.: Pharmazeutische Technologie, Thieme-Verlag, Stuttgart, 1991). De således oppnådde administreringsformer inneholder normalt 0,1 til 90 vekt% av midlet.
