Description
Foreliggende oppfinnelse angår en analogifremgangsmåte for fremgangsmåte for fremstilling av nye benzocykloalkanderivater med potent acyl-CoArkolesterolacyltransferase-(ACAT)-inhiberende aktivitet.
Forbindelsene ifølge oppfinnelsen viser i pattedyr absorpsjon av kolesterol gjennom fordøyelsestrakten og akkumulering av kolesterolestere på arterieveggen og er derfor brukbare som profylaktiske og terapeutiske midler for hyperkolesterolemi, aterosklerose og forskjellige sykdommer som stammer fra disse (for eksempel iskemiske kardiske sykdommer som nry Vardia-linfarkt, cerebrovaskulaere forstyrrelser som cerebral infarkt og cerebral apopleksi, og så videre).
TJreaderivater med en ACAT-inhiberende aktivitet er ! r -■ \~V ■•:*«-•-.■ v t i japansk KOKAI nr. 316 761/1988 og 93 569/1989 og 4 623 662. Imidlertid er ureaderivater med en bei_. , .. j-alkylsubstituent direkte på et ureanitrogenatom, enda ikke syntetisert.
Ingen ureaforbindelser med en benzocykloalkylgruppe som en direkte substituent på et ureanitrogenatom, har vært kjent for å ha god ACAT-inhibering og blodkolesterolreduserende aktivitet eller, med andre ord, vist seg å være brukbare som middel for aterosklerose.
Foreliggende oppfinnere har syntetisert forskjellige nye ureaderivater med en benzocykloalkylgruppe som direkte substituent på et nitrogenatom, og intenst søkt efter deres aktiviteter og, som et resultat, funnet at de nye forbindelser har utmerket ACAT-inhiberende aktivitet og er brukbare som medikament mot aterosklerose.
I henhold til dette angår oppfinnelsen en analogifremgangsmåte for fremstilling av terapeutisk aktive benzocykloalkanderivater med formel (I):
der
ringen A er benzen som eventuelt kan være substituert med 1 til 4 grupper valgt blant hydrogen, laverealkyl, laverealkoksy eller halogen,
R er C4_7cykloalkyl laverealkyl, tienyl laverealkyl, pyridyl laverealkyl, difenyl laverealkyl, fenyl eller fenyl laverealkyl som eventuelt er substituert med en eller flere grupper valgt blant laverealkyl, laverealkoksy, tio, halogen, hydroksy, trifluormetyl eller laverealkyltio,
Ar er fenyl substituert med en eller flere grupper valgt blant halogen eller lavere alkyl,
X er et oksygen- eller svovelatom,
1 er 0 eller 1,
m er fra og med 3 til og med 6, og
n er 0 til og med 2, eller
et farmasøytisk akseptabelt salt derav.
Foretrukne eksempler på Ar er mono- eller di-halogen(f.eks. F)-substituerte fenylgrupper. Ringen A er fortrinnsvis usubstituert. Fortrinnsvis er n lik 0, i lik 0 eller 1, og m et helt tall 3 til 6.
Således omfatter gruppen
spesielt de følgende:
Den ovenfornevnte forbindelse (I) kan foreligge i form av sitt farmasøytisk akseptable salt, for eksempel et alkali-metallsalt med karboksygruppen i forbindelse (I), for eksempel natrium- eller kaliumsaltet..
Benzocykloalkanderivatet med formel (I) kan for eksempel fremstilles ved omsetning av en forbindelse med formel (II): der substituenten har den ovenfor angitte betydning, eller et salt derav, med en forbindelse med formel (III) '
der substituentene har den ovenfor angitte betydning.
Salter av aminobenzocykloalkanderivatet (II) er blant andre salter med uorganiske eller organiske syrer som saltsyre, hydrobrom-, svovel-, fosfor-, metansulfon-, benzensulfon-, p-toluensulfon-, fumar-, ma.lein-, sitron- og vinsyre. Denne reaksjon gjennomføres generelt i et egnet oppløsningsmiddel. Et hvilket som helst oppløsningsmiddel som er inert ved reaksjonen, kan benyttes. Således kan man benytte etere som etyleter, isopropyleter, dimetoksyetan, tetrahydrofuran og dioksan, aromatiske hydrokarboner, som benzen, toluen og xylen, estere som metylacetat og etylacetat, ketoner som aceton og metyletylketon, halogenerte hydrokarboner som diklormetan og kloroform, pyridin, N,N-dimetylformamid og dimetylsulfoksyd. I tilfeller der (II) underkastes reaksjonen i form av et salt, vil reaksjonen generelt skje i betydelig grad hvis den gjennomføres i nærvær av en base som trimetylamin, trietylamin, pyridin, picolin, natriummetylat, natriumetylat, natriumhydroksyd, kaliumhydroksyd, natriumkarbonat, kaliumkarbonat for effektiv avsalting. Slik base benyttes i en mengde av 1 til 3 og fortrinnsvis 1 til 1,5 mol pr. mol (II). Reaksjonen gjennomføres generelt ved -10 til +15CTC, fortrinnsvis 0 til +80°C. (III) benyttes i en mengde av ca. 1 til 5 ekvivalenter, fortrinnsvis 1 til 2 ekvivalenter i forhold til (II). Reaksjonstiden som er nødvendig kan variere avhengig av utgangsstoffer, oppløsningsmiddel, reaksjonstemperatur og andre faktorer. Generelt blir imidlertid reaksjonen gjennomført i et tidsrom på 5 minutter til 24 timer, og fortrinnsvis 10 minutter til 6 timer.
Blant forbindelsene med formel (I) som således fremstilles, kan de der ringen A, gruppen Ar og/eller gruppen R har minst en laverealkoksygruppe som en substituent på benzenringen deri, omdannes til de tilsvarende forbindelser med en hydroksylgruppe i stedet for den laverealkoksygruppe, ved omsetning av forbindelsene (I) enten som de er i de respektive reaksjonsblandinger eller efter isolering, ved kjente prosedyrer som nevnt nedenfor, for eksempel med bortribromid. Denne reaksjon gjennomføres generelt i et oppløsningsmiddel, for eksempel et halogenert hydrokarbon, som diklormetan, kloroform eller karbontetraklorid, aromatiske hydrokarboner som benzen eller toluen, ved ca. -20 til +80°C, fortrinnsvis -5 til +30°C. Bortribromid benyttes i en mengde av ca. 1 til 10 ekvivalenter, fortrinnsvis 1 til 5 ekvivalenter, pr. laverealkoksygruppe.
De ønskede forbindelser (I) som fremstilles på denne måte kan renses og gjenvinnes ved bruk av i og for seg kjente sepa-rerings- eller renseprosedyrer som konsentrasjon, opp-løsningsmiddelekstrahering, kolonnekromatografi eller omkrystallisering.
Foretrukket blant forbindelsene (I) som kan fremstilles på denne måte, er for eksempel forbindelser med formel (Ia): /v nh~O^ f
(CbHiB-i)
der Ra er en benzylgruppe som eventuelt kan ha én eller flere substltuenter, X er et oksygen- eller svovelatom og i og m.er som angitt ovenfor, samt forbindelser med formel (I<b>):
der Ra og m er som angitt ovenfor. I de ovenfor angitte formler kan benzylgruppen som representeres ved Ra, ha én eller flere av de samme substituenter som nevnt ovenfor for
R.
Forbindelsene (I) har potent acyl-CoA:kolesterolacyltrans-ferase(ACAT)-inhiberende aktivitet så vel som svak akutt toksisitet og svak kronisk toksisitet. ACAT er et enzym som katalyserer forestringen av kolesterol med høyere fettsyrer. Det er kjent at ACAT spiller en viktig rolle ved absorpsjon av kolesterol i tynntarmen og den intracellulære akkumulering av kolesterolestere. Derfor kan en ACAT-inhibitor inhibere absorpsjon av dietærkolesterol gjennom fordøyelseskanalen for å hindre at blodkolesterolnivået øker, og samtidig inhibere intracellulær kolesterolesterakkumulering i arteriosklerot-iske foci for derved å redusere fremskridelsen av aterosklerose. I henhold til dette er forbindelsene (I) ifølge oppfinnelsen brukbare som sikre profylaktiske og terapeutiske midler mot hyperkolesterolemi, aterosklerose og sykdommer som stammer fra disse (for eksempel iskemiske hjertesykdommer som myokardialinfarkt, cerebrovaskulære sykdommer som cerebral-infarkt og cerebralapopleksi), i pattedyr som mus, rotter, hamstere, kaniner, katter, hunder, hester, kveg, sauer, aper eller mennesker).
Ut fra de ovenfornevnte medisinske aspekter kan forbindelsen med formel (I) blandes med farmakologisk aksepterbare egnede ...bærere, -midler eller fortynningsmidler for å gi doserings-former som pulvere, granulater, tabletter, kapsler eller injeksjonspreparater, som skal administreres enten oralt eller ikke-oralt. For å inhibere kolesterolabsorpsjon er den orale administreringsmåte foretrukket. Dosen kan variere avhengig av typen forbindelse (I), administreringsvei, symptom, pasientens alder og andre faktorer. Når det gjelder oral administrering til voksne hyperkolesterolemiske pasient-er kan for eksempel den daglige dose pr. kg kroppsvekt ligge innen området 0,005 til 100 mg, spesielt 0,05 til 50 mg og aller helst 0,5 til 10 mg, og slike daglige doser administreres fortrinnsvis som en enkelt dose eller i to eller tre oppdelte doser.
Utgangsforbindelsene for fremstilling av forbindelsene (I) som fremstilles ifølf opfinnelsen, kan fremstilles ved en i og for seg kjent metoGii, for eksempel på følgende måte:
Symbolene i disse formler er som angitt ovenfor.
I disse formler er R<1> og R<2> hver et hydrogenatom eller en hydrokarbongruppe, som eventuelt kan ha én eller flere substituenter, og der de andre symboler er som angitt ovenfor.
Symbolene i disse formler er som angitt ovenfor.
Prosess A:
Den reduktive alkylering av aminet (V) med benzocyklo-alkanonet (IV) kan generelt gjennomføres i et oppløsnings-middel. Oppløsningsmidlet som benyttes kan være et hvilket som helst oppløsningsmiddel hvis det er inert ved reaksjonen. Således kan man for eksempel benytte alkoholer som metanol, etanol og isopropanol, etere som etyleter, isopropyleter, dimetoksyetan, tetrahydrofuran og dioksan, aromatiske hydrokarboner som benzen, toluen og xylen, samt dimetylformamid og dimetylsulfoksyd. Blandede oppløsningsmidler bestående av disse kan også benyttes. Reduksjonsmidlet som benyttes i denne fremgangsmåte er f.eks. natriumborhydrid, litiumborhydrid, natriumcyanoborhydrid, litiumaluminiumhydrid eller lignende. Generelt blir et slikt reduksjonsmiddel benyttet i en mengde av 0,5 til 5 mol, fortrinnsvis 0,5 til 2 mol pr. mol (IV). Reduksjonen kan gjennomføres generelt ved-10 til +150'C, fortrinnsvis -5 til +100°C. Reaksjonsperioden er generelt 15 minutter til 24 timer, fortrinnsvis 30 minutter til 8 timer.
Reduksjonsreaksjonen kan gjennomføres ikke bare ved bruk av de reduksjonsmidler som er nevnt ovenfor, men også som katalytisk reduksjon ved bruk av en egnet katalysator. Som slik katalysator skal for eksempel nevnes palladiumkataly-' satorer, som sort palladium, palladium på trekull og palladiumklorid, platinakatalysatorer som platinaoksyd og sort platina, samt Raney-nikkel. Katalysatoren benyttes generelt i en mengde av 0,001 til 2 mo, fortrinnsvis 0,01 til 1 mol pr. mol (IV). Reaks jonstrykket er 1 til 100 atmos-faerer/cm2, fortrinnsvis 1 til 20 atmosfærer/cm<2>. En slik reduksjonsreaksjon kan generelt gjennomføres ved -10 til +150°C, fortrinnsvis ved -5 til +100°C. Reaksjonsperioden er generelt 30 minutter til 12 timer, fortrinnsvis 30 minutter til 5 timer.
Den ovenfornevnte reduksjonsreaksjon og katalytiske reduksjon kan gjennomføres i nærvær av en sur katalysator for å fremme reaksjonen. Brukbar som slik sur katalysator er organiske syrer som maur-, eddik-, propion-, trifluoreddik-, metansulfon-, benzensulfon-, p-toluensulfon- og kamfersulfonsyre, samt videre organiske syrer som saltsyre, svovel- eller fosforsyre. Generelt benyttes syren i en mengde av 0,5 til 20 ml, fortrinnsvis 1 til 10 mol pr. mol (IV).
Prosess B:
Utgangsmaterialet (VIII) kan fremstilles ved reduktiv alkylering av aminobenzocykloalkanet (VI) med karbonyl-forbindelsen (VII) idet vesentlige på samme måte som under prosess A som beskrevet ovenfor.
Prosess C:
Reaksjonen (acyleringen) av forbindelsen (VI) med syre-kloridet (IX) gjennomføres generelt i et oppløsningsmiddel. Brukbar som slike oppløsningsmidler er ethvert oppløsnings-middel som er inert ved reaksjonen, for eksempel halogenerte hydrokarboner som karbontetraklorid, kloroform, diklormetan og 1,1,2,2-tetrakloretan, estere som etylacetat og metylacetat, ketoner som aceton og metyletylketon, etere som etyleter, isopropyleter, tetrahydrofuran og dioksan, aromatiske hydrokarboner som benzen, toluen og xylen, samt dimetylformamid og dimetylsulfoksyd såvel som blandinger derav. Når reaksjonen gjennomføres som en Schotten-Baumann-acylering, kan vann og blandinger av vann og de ovenfornevnte oppløsningsmidler også benyttes. Reaktive derivater (for eksempel blandede syreanhydrider, aktive estere) for de tilsvarende syrer kan benyttes i stedet for (IX). Denne acyleringsreaksjon kan gjennomføres i nærvær av et deacidifiserende middel eller en syreakseptor. Som eksempler på slike deacidifiserende midler skal nevnes organiske baser som trimetylamin, trietylamin, pyridin, picolin, dimetylanilin og dietylanilin, og uorganiske baser som natriumhydroksyd, kaliumhydroksyd, natriumkarbonat, kaliumkarbonat, natrium-hydrogenkarbonat og kaliumhydrogenkarbonat. Generelt blir deacidifiseringsmidlet benyttet i en mengde av 1 til 5 mol, fortrinnsvis 1 til 2 mol pr. mol (IX). Reaksjonstemperaturen er generelt -20 til +100'C, fortrinnsvis 10 til 50°C. Reaksjonsperioden er generelt 15 minutter til 24 timer, fortrinnsvis 30 minutter til 8 timer. Acylaminoforbindelsen (X) som oppnås på denne måte omsettes med et reduksjonsmiddel for derved å gi (XI). Som eksempler på slike reduksjonsmidler skal nevnes de som er nevnt ovenfor under henvisning til prosess A, så vel som blandinger av en Lewis-syre som aluminiumklorid, sinkklorid, bortrifluorideterat og litiumaluminiumhydrid, og en blanding av en organisk syre, som eddik- eller trifluoreddiksyre, og natriumborhydrid, blant andre. Ethvert oppløsningsmiddel som er inert ved reaksjonen kan benyttes. Som eksempler skal nevnes de oppløsningsmidler som kan benyttes under prosess A. Reaksjonen gjennomføres generelt ved en temperatur på -10 til +150°C, fortrinnsvis -5 til +100°C, i et tidsrom på 30 minutter til 20 timer, fortrinnsvis 30 minutter til 8 timer. Utgangsforbindelsen
(II) så vel som forbindelsene (VIII) og (XI) [idet hver er specier av (II)], benyttes som materialer for fremstilling av forbindelsene ifølge oppfinnelsen, enten efter isolasjon derav ved kjente prosedyrer som nevnt ovenfor, eller i form av reaksjonsblandinger.
Utgangsforbindelsene (IV) og (VI) kan syntetiseres ved kjente prosesser som for eksempel beskrevet av Miyake et al. i "Journal of the Takeda Research Laboratories", 44, 171 (1985) og idem., 45, 122 (1985) eller modifiseringer derav. Forbindelsene (V), (VII) og (IX) kan syntetiseres ved per se kjente prosesser.
Aktivitet:
De følgende farmakologiske prøveresultater antyder at benzocykloalkanderivatene (I) ifølge oppfinnelsen er av stor brukbarhet. 1. Acyl-CoA:kolesterolacyltransferase(ACAT )-inhiberende aktivitet
Prøvemetode:
Et ACAT-enzympreparat ble oppnådd fra tynntarm-mucosa-mikrosomfraksjonen fra 6 uker gamle Sprague-Dawley hannrotter som var fastet i 20 timer slik det beskrives av Heider et al. i "Journal of Lipid Research", 24, 1127 (1982).
ACAT-aktiviteten ble beregnet ved å bestemme utbyttet av merket kolesterolester fra [1-^-^C] oleoyl-CoA og endogen kolesterol ved bruk av metoden til Helgerud et al. i "Journal of Lipid Research", 22, 271 (1981).
Resultater:
Inhiberingsprosentandelene av den merkede kolesterolester-dannelse ved 10-^ M for prøveforbindelsene er vist i tabell I som ACAT-inhiberende aktivitetsindekser.
De data som er gitt i tabell 1 viser at forbindelsene (I) som fremstilles ifølge oppfinnelsen slik de representeres ved de respektive eksempler, har en potent ACAT-inhiberende aktivitet. 2. Plasmakolesterolreduserende aktivitet i kolesterolfylte rotter.
Prøvemetode:
7 uker gamle Sprague-Dawley hannrotter- ble matet med 1 % kolesteroldiett (inneholdende 0,5 % kolinsyre og 5 % oliven-olje) i 3 dager, og derefter gruppert efter plasmakole-sterolnivå og ytterligere matet med den samme diett inneholdende 0,01 # prøveforbindelse i 4 dager. Blodprøver ble samlet 8:30 a.m. til 10:00 a.m. mens dyrene var satinert, cg plasmakolesterolnivåene ble bestemt enzymatisk. Inntak av forbindelsen ble beregnet fra næringsmiddelinntaksdata.
Resultater:
Slik man ser i tabell 2, forårsaker prøveforbindelsen en signifikant reduksjon av plasmakolesterolnivået i kolesterol-anrikede dyr.
De data som er gitt i tabell 2 viser at forbindelsene (I) ifølge oppfinnelsen, som representert ved forbindelsen i eksempel 1, har potent plasmakolesterolreduserende aktivitet.
Eksempler
De følgende referanseeksempler og arbeidseksempler skal illustrere oppfinnelsen uten imidlertid å begrense opp-finnelsens ramme.
I referanseeksemplene og eksemplene ble eluering efter kolonnekromatografi gjennomført under observasjon ved tynnsjiktskromatografi (TLC). Ved TLC-observasjonen ble det benyttet silikagel 60 F254, TLC-plater fra Merck og frem-kallingsoppløsningsmidlet var det samme som ble benyttet som elueringsmiddel ved kolonnekromatografi, og en UV-detektor ble benyttet som detekteringsmiddel. Silikagel 60 (Merck; 70-230 mesh) ble benyttet som kolonnepaknlngs-silikagel.
I eksempler og referanseeksempler er de følgende forkortelser benyttet: mg for milligram; g for gram; ml for milliliter; smp. for smeltepunkt.
Uttrykket "romtemperatur" betyr en temperatur innen det omtrentlige området 15 til 25°C.
Eksempel 1
Trietylamin (0,28 ml) ble satt til en suspensjon av 2-(2-klorbenzylamino)indan-hydroklorid (0,59 g) i diklormetan (6,0 ml), og blandingen ble omrørt i 10 minutter hvorefter 2,4-difluorfenylisocyanat (0,26 ml) ble tilsatt dråpevis. Den resulterende blanding ble omrørt i 30 minutter, og derefter vasket med vann og tørket over vannfri MgSC^. Oppløsnings-midlet ble destillert av og resten krystallisert ved tilsetning av eter:heksan, hvorved man oppnådde N-(2-klor-benzyl)-N'-(2,4-difluorfenyl)-N-(2-indanyl)urea (0,78 g, 94,0 %). Omkrystallisering fra etanol gav farveløse prismer (0,59 g, 71,7
