Description
Denne oppfinnelse angår en fremgangsmåte for fremstilling av nye amid-derivater, og særlig nye acylanilider som har antiandrogen aktivitet.
Det er kjent mange acylanilider som har antiandrogen aktivitet. Spesielt er forbindelsen
hvor R er hydrogen, som er kjent som Flutamid, under utvikling for anvendelse som et antiandrogent middel. Det antas at flutamid oksyderes in vivo til den tilsvarende forbindelse hvor R er hydroksy.
Andre acylanilider som har antiandrogen aktivitet er kjent fra europeiske patenter 2309, 2892 og 40932, og fra japansk patent 52-128329.
I henhold til foreliggende oppfinnelse fremstilles et acylanilid med formelen:
hvor
R<1> er cyano, nitro, fluor, klor, brom eller jod, eller alkyl, alkoksy eller perfluoralkyl med hver opp til 4 karbonatomer;
R<2> er cyano, nitro, fluor, klor, brom eller jod, eller perfluoralkyl med opp til 4 karbonatomer;
R<5> er hydroksy eller acyloksy med opp til 15 karbonatomer;
R<6> er alkyl eller halogenalkyl med opp til 4 karbonatomer;
A<1> er alkylen med opp til 4 karbonatomer;
Å<2> er en direkte binding eller alkylen med opp til 4 karbonatomer;
X<1> er svovel, sulfinyl (-S0-) eller sulfonyl (-S02-);
R<7> er alkyl, alkenyl, hydroksyalkyl eller cykloalkyl med hver opp til 6 karbonatomer, eller R<7> er fenyl som bærer én eller to substituenter valgt fra hydrogen, halogen, nitro og cyano, og alkoksy og alkyltio med hver opp til 4 karbonatomer;
eller R<7> er naftyl; eller R<7> er en 5- eller 6-leddet, mettet eller umettet heterocyklisk gruppe som inneholder ett eller to heteroatomer valgt fra oksygen, nitrogen og svovel, hvilken heterocykliske gruppe kan være en enkelt ring eller kan være kondensert med en benzenring, og hvilken heterocykliske gruppe er usubstituert eller bærer én eller to halogen- eller alkyl-(med opp til 4 karbonatomer) substituenter.
Det vil sees at acylanilid-derivatet fremstilt ifølge oppfinnelsen har et asymmetrisk karbonatom, nemlig karbonatomet som bærer substituentene R 5 og R 6, og det kan derfor eksistere i racemisk og optisk aktive former. Det skal forstås at oppfinnelsen omfatter fremstilling av den racemiske form av acylanilid-derivatet og enhver optisk aktiv form som har antiandrogen aktivitet, idet det er vanlig kjent hvordan en racemisk forbindelse kan spaltes i sine optisk aktive former og hvordan den antiandrogene aktivitet kan måles i disse formene.
En egnet betydning for R<1> når den er alkyl, eller for
en alkyl-substituent i R 7 når R 7er en heterocyklisk gruppe substituert med alkyl, er f.eks. metyl eller etyl.
En egnet betydning for R<1> når den er alkoksy, eller for
en alkoksy-substituent i R 7 når R 7 er fenyl substituert med alkoksy, er f.eks. metoksy eller etoksy.
En egnet betydning for R 1 eller R 2 når den er alkyltio eller perfluoralkyl, eller for en slik substituent i R<7>
nar R 7er fenyl som bærer en slik substituent, er f.eks. metyltio, etyltio, trifluormetyl eller pentafluoretyl.
En egnet betydning for en halogen-substituent i R<7>
er fenyl eller en heterocyklisk gruppe substituert med halogen, er fluor, klor, brom eller jod.
En egnet betydning for R når den er acyloksy, er f.eks. alkanoyloksy eller aroyloksy med hver opptil 15 karbonatomer, f.eks. acetoksy, propionyloksy, dekanoyloksy, dodekanoyloksy eller benzoyloksy.
R<5> er fortrinnsvis hydroksy.
En egnet betydning for R^ når den er alkyl eller halogenalkyl, er f.eks. metyl, etyl, n-propyl, fluormetyl, difluormetyl, trifluormetyl, pentafluoretyl, klormetyl, diklormetyl eller triklormety1. R er fortrinnsvis metyl eller trifluormetyl, særlig metyl.
En egnet betydning for A 1 eller A 2 når den er alkylen,
er f.eks. metylen, etylen, etyliden (CH36h-), trimetylen,
tetrametylen, 1-metyletylen
eller 2-metyletylen-
En egnet betydning for
R 7 når den er alkyl, alkenyl,
hydroksyalkyl eller cykloalkyl, er f.eks. metyl, etyl,
n-propyl, isopropyl, n-butyl, allyl, 2-metylprop-2-enyl, 2-hydroksyetyl, cyklopentyl eller cykloheksyl.
7
En egnet betydning for R nar den er en
heterocyklisk gruppe, er f.eks. furyl, tienyl, pyrrolyl, pyridyl, imidazolyl, tiazolyl, pyrimidinyl, tiadiazolyl, triazolyl, benzimidazolyl, benzotiazolyl, indolyl, benzotienyl, benzofuryl, kinolyl, isokinolyl eller 1,2-dihydro-2-oksokinolyl.

hvor R og A har de ovenfor angitte betydninger.
En egnet betydning for Z 2 er f.eks. en halogen- eller sulfonyloksy-gruppe, f.eks. klor, brom, jod, metansulfonyloksy eller p-toluensulfonyloksy. Den ovennevnte omsetning utføres fortrinnsvis i et inert fortynningsmiddel eller oppløsningsmiddel, f.eks. tetrahydrofuran, og i nærvær av en base, f.eks. natriumhydrid.
Epoksydet anvendt som utgangsmateriale kan oppnås ved dannelse av epoksydet av det tilsvarende umettede acylanilid med f.eks. en persyre.
En tredje foretrukket fremgangsmåte for fremstilling av et acylanilid med formel I hvor R er hydroksy, omfatter omsetning av en forbindelse med formelen:
12 fi
hvor R , R og R har de ovenfor angitte betydninger,
med en organisk metallforbindelse med formelen: R<7->A<2->X<1->A<1->M
12 7 1
hvor A , A , R og X har de ovenfor angitte betydninger, og M er et metall-radikal, f .eks. litiumradikalet.
Sistnevnte omsetning utføres fortrinnsvis i et inert oppløsningsmiddel, f.eks. dietyleter eller tetrahydrofuran, ved en lav temperatur, f.eks. mellom -60 og -100°C.
Et acylanilid med formel I hvor R 5 er hydroksy, kan fremstilles ved hydrolyse av det tilsvarende acylanilid hvor
5
R er acyloksy.
Et acylanilid med formel I hvor R^ er acyloksy, kan fremstilles ved acylering av det tilsvarende acylanilid hvor R 5 er hydroksy.
Et acylanilid med formel I hvor X<1> er sulfinyl eller sulfonyl, kan fremstilles ved oksydasjon av det tilsvarende acylanilid hvor X<*> er svovel. Oksydasjonsmidlet og betingelsene som anvendes vil avgjøre om en sulfinyl- eller en sulfonylforbindelse dannes. Oksydasjon med natriummetaperjodat i meta-noloppløsning ved eller under laboratorietemperatur vil således normalt omdanne en tio-forbindelse til den tilsvarende sulfinylforbindelse, og oksydasjon med en persyre, f.eks. m-klorperbenzoesyre i metylenkloridoppløsning ved eller over laboratorietemperatur vil normalt omdanne en tio-forbindelse til den tilsvarende sulfonylforbindelse.
Et racemisk acylanilid fremstilt ifølge oppfinnelsen,
hvor R^ er hydroksy, kan spaltes i sine optiske isomerer ved
å danne en ester ved hydroksygruppen R 5 med en optisk aktiv syre, f.eks. (-)-kamfansyre, separere de således oppnådde diastereoisomere estere, ved fraksjonert krystallisasjon eller fortrinnsvis ved hurtig-kromatografi, og derefter hydrolysere hver separate ester til alkoholen. Alternativt kan et optisk aktivt acylanilid med formel I oppnås ved anvendelse av hvilken som helst av de ovenstående fremgangsmåter med et optisk aktivt utgangsmateriale.
Som angitt ovenfor har acylanilidene med formel I antiandrogene egenskaper som kan vises ved deres evne til å redusere vekten av sædblæren til en voksen hannrotte når de administreres oralt i 4 påfølgende dager. Et acylanilid fremstilt ifølge oppfinnelsen kan derfor anvendes ved behandling av f.eks. ondartet eller godartet prostata-sykdom eller androgen-avhengige sykelige tilstander så som acne, hirsutisme eller seborré hos varmblodige hvirveldyr, innbefattet mennesker. De kan også anvendes for å forbedre ovulasjon i husdyr.
Et foretrukket acylanilid fremstilt ifølge oppfinnelsen
er opptil 10 ganger mer aktivt som antiandrogen enn de kjente kjemisk beslektede antiandrogener flutamid og hydroksyflutamid. Ved en dose av acylanilidet fremstilt ifølge oppfinnelsen som gir antiandrogen aktivitet i rotter, er det ikke påvist symptomer på toksisitet.
Acylanilidet fremstilt ifølge oppfinnelsen kan administreres til et varmblodig dyr i form av et farmasøytisk eller veterinær-medisinsk preparat som omfatter acylanilidet sammen med et farmasøytisk godtagbart fortynningsmiddel eller bærer.
Preparatet kan være i en form som er egnet for oral dosering, som en tablett, kapsel, vandig eller oljeaktig oppløsning eller suspensjon eller emulsjon. Det kan alternativt være i form av en steril oppløsning eller suspensjon som er egnet for parenteral administrering, det kan være i form av en salve eller væske for lokal administrering, eller det kan være i form av en stikkpille for anal eller vaginal administrering.
Preparatet kan i tillegg inneholde ett eller flere lege-midler valgt fra anti-østrogene midler, f.eks. tamoxifen, aromatase-inhibitorer, f.eks. testolakton eller aminoglutetamid; progestiner, f.eks. medroksyprogesteron-acetat; inhibitorer av gonadotropin-sekresjon, f.eks. danazol; LH-RH-analoger, f.eks. buserelin; cytotoksiske midler, f.eks. cyklofosfamid; antibiotika, f.eks. penicillin eller oksytetracyklin; og antiinflammatoriske midler, f.eks., særlig for lokal anvendelse, fluocinolon-acetonid.
Et acylanilid fremstilt ifølge oppfinnelsen administreres normalt til et varmblodig dyr i en dose på mellom 0,1 mg og 125 mg pr. kg kroppsvekt.
Oppfinnelsen illustreres av de følgende eksempler:
