Description

Foreliggende oppfinnelse angår en fremgangsmåte til fremstilling av fenyl-lavere-alkylaminer som kan brukes som anti-inflammatoriske midler.
Mange typer organiske forbindelser kan brukes som anti-inflammatoriske midler, men mange slike midler er sure,
dette gjelder f.eks. a-(3-benzoylfenyl)propionsyre, vanligvis kjent som ketoprofen (britisk patent nr. 1.164.585). Slike sure midler er ofte irriterende, og de kan i visse tilfeller fremkalle mavesår når de tilføres oralt. Det er således et stort behov for anti-inflammatoriske midler som ikke er irriterende på mavens slimhinner, f.eks. forbindelser med en basisk aminfunksjon. Skjønt det i den kjemiske litteratur er beskrevet en rekke amin-substituerte forbindelser med anti-inflammatorisk aktivitet [se f.eks. US-patentene 3.770.748 og 3.803.127, (N-fenylpolymetyleniminer), US-patentene 3.772.311 og 3.773.772, (polymetylenimino-lavere-alkanoylpyrazoler), US-patent 3.773.944, (1-[3-aminopropyl]ftalaner), US-patent 3.801.594, (3-amino-lavere-alkylindoler), US-patent 3.810.985, (4-anilino-l,3,5-triaziner) og fransk patent 1.549.342, (4-[benzoylfenylmetyl]-morfoliner)], så er det ingen slike basiske forbindelser kommersielt tilgjengelige, og ingen er kjent for å være under-
søkt av farmakologer for mulig kommersiell utvikling. Man har derfor stadig vært på jakt etter et effektivt ikke-surt, anti-inf lammatorisk middel som kan utvikles kommersielt.
Foreliggende oppfinnelse angår forbindelser méd formel:
hvor gruppen representerer representerer lavere-alkyl eller hvor gruppen
representerer hydrogen.
Med begrepene lavere alkyl forstås mettede, enverdige, allfatiske radikaler, slik som forgrenede radikaler med fra 1-4 karbonatomer, f.eks. metyl, etyl, propyl, isopropyl, butyl, sek-butyl og isobutyl.
Forbindelser med formel Ia hvor/C=X representerer
fremstilles ved å omsette ét 3-(fenyl-CO)-fenyl-CHR_-halogenid med formel XIII med morfolin, ifølge reaksjonsskjemaet: hvor R~har samme betydning som angitt ovenfor og Hal er halogen. Reaksjonen utføres ved å omsette en oppløsning av halogenider med et molart overskudd av morfolin ved romtemperatur i et.inert organisk oppløsningsmiddel, f.eks. metanol, etanol, isopropanol eller DMF, hvorav det sistnevnte oppløsningsmiddel er det fore-trukne. Forbindelser med formel Ia hvor gruppen representerer fremstilles fra de tilsvarende forbindelser hvor
representerer C=0 ved å omdanne sistnevnte til oksimet
(ved oppvarming av sistnevnte med hydroksylamin i et inert organisk oppløsningsmiddel, f.eks. en lavere alkanol) og redusere oksimet til aminet med natrium i en lavere alkanol.
De nye forbindelser fremstilt ifølge foreliggende oppfinnelse er forbindelsene med formel Ia, samt deres syreaddisjonssalter. Forbindelser med formel Ia i fri baseform kan om-
dannés til syreaddisjonssaltformen ved å reagere basen med en
j syre. På lignende måte kan den frie base regenereres fra syre-addis jonssaltet på vanlig måte, dvs. at man behandler saltene med en kald, svak vandig base, f.eks. alkalimetallkarbonater og alkalimetallbikarbonater. De således regenererte baser kan igjen omsettes med samme eller forskjellig syre hvoretter man får et annet syreaddisjonssalt. Alle de nye baser og alle deres syreaddisjonssalter er således lett omdannbare til hverandre.
Formel Ia omfatter således ikke bare selve basene med nevnte formel, men også representerer alle forbindelser med nevnte formel enten det er i form av en fri base eller i form
av et syreaddisjonssalt. Man har funnet at både basene og deres syreaddisjonssalter har de farmakologiske aktiviteter som er mer detaljert beskrevet nedenfor. Denne aktivitet kan utnyttes for farmasøytiske formål enten ved at man anvender de frie baser som sådan eller'deres syreaddisjonssalter, dvs. ved hjelp av syrer hvis anioner er uskadelige for dyreorganismer i effektive doser slik at man oppnår deønskede effekter uten at nevnte anioner frembringer bivirkninger.
Når man ønsker å utnytte de farmakologiske aktiviteter til de fremstilte forbindelser, er det foretrukket å bruke farmasøytisk akseptable salter. Skjønt vann-uoppløselighet, høy toksisitet og mangel av krystallinsk karakter kan gjøre noen spesielle salttyper uegnede eller mindre ønskelige for bruk i et gitt farmasøytisk tilfelle, så kan vann-uoppløselig eller toksiske salter omdannes til de tilsvarende farmasøytisk akseptable baser ved å dekomponere saltet med en vandig base slik det er forklart ovenfor, eller alternativt kan det omdannes til farmasøytisk akseptable syreaddisjonssalter ved en dobbelt de-komponeringsreaksjon som innbefatter anionet, f.eks. ved ioneut-bytting.
Foruten at de kan brukes for farmasøytiske formål, kan saltene brukes for å karakterisere eller identifisere derivater av de frie baser eller for å isolere eller å lense slike baser. Som alle andre syreaddisjonssalter kan slike rensningssalt-derivater hvis det er ønskelig, brukes for å regenererte de farmasøytisk akseptable frie baser ved at nevnte salter rea-geres med vandig base eller alternativt kan basen omdannes til farmasøytisk akseptable syreaddisjonssalter ved ioneutbytnings-
metoder.
Det fremgår av det foregående at alle syreaddisjonssalter av de nye baser er brukbare og verdifulle forbindelser uansett hvorvidt de er oppløselige, toksiske, eller har en uegnet fysisk form for de rent farmasøytiske formål, og alle forbindelser inngår således i oppfinnelsen.
Egenskapene til de fremstilte forbindelser ligger i basene eller de kationiske former av de nye N-{3-[R^-(fenyl)-C(=X)]-fenyl^lavere-alkyl}morfoliner og ikke i en spesiell syre-gruppe eller syreanion som er forbundet med saltformene av disse forbindelser, og disse syregrupper og anioner er i seg selv hverken nye eller kritiske og kan følgelig innbefatte ethvert syreanion eller syrelignende stoff som. er i stand til å danne salter med basene. I vandige oppløsninger vil således baseformen eller et vannoppløselig syreaddisjonssalt av forbindelser med formel I både ha en vandig protonert kation eller ammoniumion.
Passende syreaddisjonssalter er således de som er fremstilt av forskjellige syrer, slik som maursyre, eddiksyre, isosmørsyre, alfa-merkaptopropionsyre, eplesyre, fumarsyre, rav-syre, succinaminsyre, vinsyre, sitronsyre, melkesyre, benzoe-syre, 4-metoksybenzosyre, ftalsyre, antranilinsyre, 1-naftalen-karboksylsyre, kanelsyre, cykloheksankarboksylsyre, mandelsyre, tropinsyre, krontonsyre, acetylendikarboksylsyre, sorbinsyre, 2-furankarboksylsyre, kolinsyre, pyrenkarboksylsyre, 2-pyridin-karboksylsyre, 3-indoleddiksyre, kininsyre, sulfaminsyre, metansulfonsyre, isetioninsyre, benzensulfonsyre, p-toluensulfon-syre, benzensulfinsyre, butylarsonsyre, dietylfosfonsyre, p-amino-fenylarsinsyre, fenylstibninsyre, fenylfosforsyre, metylfosfinsyre, fenylfosfinsyre, flussyre, saltsyre, hydrobromsyre, hydrojodsyre, perklorsyre, salpetersyre, svovelsyre, fosforsyre, blåsyre, fosforvolframsyre, molybdensyre, fosformolybdensyre, pyrofosfor-syre, arsensyre, pikrinsyr.e, pikroloninsyre, barbitursyre, bortri-fluorid og lignende.
Syreaddisjonssaltene kan fremstilles ved å omsette den frie base og syren i et organisk oppløsningsmiddel hvoretter man isolerer saltet direkte eller ved å konsentrere oppløsningen.
På grunn av tilstedeværelsen av et asymmetrisk senter, forbindelser med formel Ia, dvs. det karbonatom som er til-støtende til fenylringen til hvilket R^-gruppen er knyttet eller karbonatomer i ^CHN^-gruppen, så vil forbindelser med formel Ia eksistere i stereokjemiske isomere former som alle inngår i foreliggende oppfinnelse. Hvis det er ønskelig, kan man-isolere eller fremstille en spesiell stereokjemisk form, noe som kan gjøres ved at man bruker i seg selv kjente fremgangsmåter.
I standard farmakologiske prøver har man funnet at forbindelser med formel Ia har meget verdifull anti-inflammatorisk aktivitet og kan følgelig brukes som anti-inflammatoriske midler. Den anti-inflammatoriske aktivitet ble bestemt ved å bruke
(1) hemmingen av karrageenin-indusert fotødemprøve som i alt
vesentlig er beskrevet av Van Arman et al., J. Pharmacol, Exptl. Therap. 150, 328 (1965) modifisert av Winter et al., Proe. Soc. Exp. Biol. og Med. 111, 544 (1962) og (2) en modifikasjon av hemmingen av hjelpemiddel-indusert arthritisprøven som er beskrevet av Pierson, J. Chronic Diseases 16, 863 (1963) og Glenn et al., Am. J. Vet. Res. 26, 1180 (1965),
Forbindelser med formel. Ia kan fremstilles slik at de kan opparbeides i enhetsdoseformer for tabletter eller kapsler for oral tilførsel, enten alene eller i kombinasjon med egnet fortynningsmidler, slik som kalsiumkarbonat, stivelse, laktose, talkum, magnesiumstearat, gummi acacia og lignende. Videre kan forbindelsen opparbeides for oral tilførsel i vandig alkohol, glykol eller oljeoppløsninger eller i olje-vannemulsjoner på samme måte som man gjør i vanlig farmasøytisk industri.
Foreliggende forbindelsers molekylstruktur ble bestemt på basis av studier over spektra i infrarødt, ultrafiolett, samt kjernemagnetiske spektra, og bekreftet ved at det var en overens-stemmelse mellom beregnet og funnet verdi for de forskjellige elementer i forbindelsene.
Følgende eksempler illustrerer oppfinnelsen. Alle smeltepunkter er ukorrigerte.
Eksempel 1
En blanding av 28,62 g (0,09 mol) 4-(3-benzoylfenyl)metyl-morfolinhydroklorid og 9,6 3 g (0,14 mol) hydroksylaminhydroklorid i 35 ml 95% etanol og 27 ml vann, ble behandlet under omrøring med 21,68 g (0,54 mol) pulverformig natriumhydroksyd og blandingen ble tilbakeløpskokt i 1/2 time. Blandingen ble deretter avkjølt,
fortynnet med vann og ekstrahert flere ganger med benzen. Benzenekstraktene ga ved fordampning til tørrhet, et fast
materiale som ble omkrystallisert fra benzen/heksan til 13,9 g 4-(3-benzoylfenyl)metylmorfolinoksim (smp. 145-167°C).
Eksempel 2
En oppløsning av 8,12 g (0,027 mol) 4-(3-benzoylfenyl)-metyl-morfolinoksim i absolutt etanol, ble brakt til tilbakeløps-koking og behandlet med 6,45 g (0,28 mol) natriummetall tilsatt i små biter. Tilbakeløpskoking ble fortsatt inntil alt natrium var oppløst og oppløsningen ble deretter avkjølt, fortynnet med vann, surgjort med fortynnet saltsyre, inndampet til et volum på ca. 100 ml i vakuum og deretter ekstrahert med dietyleter. De organiske ekstrakter ble inndampet til tørrhet, en metanol-oppløsning av resten ble behandlet med eterholdig hydrogenklorid og oppløsningen inndampet til tørrhet, hvilket ga 8,3 g 4-{[3-(a-aminobenzyl)fenyl]metyl}morfolindihydrokloridmonohydrat, smp. 270-274°C.

En oppløsning av 11,0 g (0,126 mol) morfolin i 24 ml dimetylformamid ble omrørt ved hjelp av ytre avkjøling i et vann-bad og behandlet iløpet av 10 minutter med en oppløsning av 17,35 g (0,06 mol) 1-(3-bénzoylfenyl)-1-brometan i 24 ml dimetylformamid. Etter at tilsetningen var fullstendig, ble blandingen omrørt i ytterligere 1 time ved romtemperatur. Den ble deretter filtrert, filteret vasket med eter og filtratet helt over i 125 ml vann og blandingen ekstrahert to ganger med eter. Isolering av produktet i form av en fri base fra eterekstraktene på vanlig måte gå 14,8 g av et oljeaktig produkt som ble kromato-grafert på aluminiumoksyd idet man som elueringsmiddel brukte en 1:1 eter/heksanoppløsning, og dette ga 12 g av 4-[l-(3-benzoylfenyl)etyl]morfolin som en blekt gul olje.
Analyse:
Beregnet for C19<H>21N02: C 77,26; H 7,17; N 4,74
Funnet: C 76,95; H 7,11; N 4,61.
Biologiske prøveresultater
Nevnte N-{3-[F^-(fenyl)-C(=X)]-fenyl-lavere-alkyl}-morfoliner med formel Ia er blitt prøvet i de kjente karragenin-ødem (CE) og hjelpemiddel arthritis (AA) prøver, og man fant at de hadde anti-inflammatorisk aktivitet. De oppnådde resul-tater angitt som prosenthemming.ved en dose uttrykt i millimol (yM)/kg kroppsvekt, er angitt i tabell A nedenfor. For sammen- lignende formål har man også oppgitt data som ble oppnådd i en karrageeninødemprøve med en referanseforbindelse (angitt "Ref."), dvs. 4-[(3-benzoylfenyl)metyl]morfolin, beskrevet i fransk patent 1.549.342. Alle data ble oppnådd ved oral tilførsel.
