Description
Oppfinnelsen angår en fremgangsmåte for fremstilling av nye substituerte pyrrolidinon-derivater.
De nye forbindelsene tjener til å forbedre cerebral insuffisiens, og har vist seg meget virksomme i passende dyre-forsøk.
Som strukturelt lignende nootropika er 1-karbamoylmetyl-pyrrolidin-2-on (Pirazetam), 1-(p-metoksybenzoyl)-pyrrolidin-2-on (Anirazetam) og 1-karbamoylmetyl-4-hydroksy-pyrrolidin-2-on (Oxirazetam) allerede beskrevet i litteraturen, se B. J. R. Nicolaus, Drug Development Res., 2^464 (1982),
P. L, Paytasch, J. Amer. Chem. Soc, 12, 1415 (1950).
Det har nå vist seg at innføringen av en sidekjede med
en aminokarbonylfunksjon i pyrrolidinon-molekylet, resulterer i både en vesentlig forbedring av virkningen og en mer markert virkningsprofil i forhold til de kjente forbindelsene.
I henhold til oppfinnelsen fremstilles nye substituerte pyrrolidinoner med den generelle formel
hvor
R^er en fenylrest som kan ha en eller to metyl-, metoksy-, fluor-, klor-, brom- eller trifluormetyl-substituenter, eller en pyridylrest;
R2er hydrogen eller en rettkjedet eller forgrenet alkylrest med 1-4 karbonatomer;
R^er en rettkjedet eller forgrenet alkylrest med 1-3 karbonatomer, en hydroksyalkylrest med 2-3 karbonatomer, en fenylrest med en eller to klor-, brom-, metyl- eller metoksy-substituenter, en cykloheksylrest eller en dialkylaminoalkyl-rest, hvor hver alkylgruppe kan ha 1-3 karbonatomer;
R4er hydrogen eller en rettkjedet eller forgrenet alkylrest
med 1-3 karbonatomer, eller hvor
R~og R. sammen med nitrogenatomet, danner en piperidin-, morfolin- eller piperazin-ring, hvor ringene kan være substituert med en til to metylgrupper, og hvor piperazinringen kan ha en fenyl-, klorfenyl- eller benzyl-gruppe på nitrogenatomet i 4-stillingen, eller utgjøre nortropanyl-resten.
Sluttprodukter som har en basisk funksjon i molekylet, kan danne syreaddisjonssalter med fysiologisk akseptable syrer.
Som syrer for dette formål egner seg hydrogenhalogenid-syrer, svovelsyre, fosforsyre og aminosulfonsyre og organiske syrer som maursyre, eddiksyre, propionsyre, melkesyre, glykol-syre, glukonsyre, maleinsyre, fumarsyre, ravsyre, vinsyre, benzosyre, salicylsyre, sitronsyre, ascorbinsyre, p-toluen-sulfonsyre eller oksyetansulfonsyre.
Dannelsen av syreaddisjonssaltene skjer på kjent måte.
Foretrukne forbindelser med den generelle formel I er forbindelser hvorR^betyr en fenylrest, R2hydrogen, R^en fenylrest som eventuelt i o- og/eller p-stilling er substituert med klor, eller eventuelt sammen med R^og nitrogenatomet, utgjør en basisk rest, ogR^betyr hydrogen.
Spesielt interessante er forbindelser med den generelle formel I, hvor R^betyr fenyl, R2hydrogen, R^dialkylaminoalkyl eller p-klorfenyl og R^hydrogen, eller hvor R^og R^sammen med nitrogenatomet, danner en piperazinring som eventuelt kan være substituert med metyl i 4-stillingen. Spesielt skal nevnes forbindelsene 4-(N-metylpiperazinyl-karbonylaminometyl)-1-benzylpyrrolidin-2-on og 4-(p-klorfenylamino-karbonylamino-metyl)-1-benzylpyrrolidin-2-on.
Oppfinnelsen angår følgende fremgangsmåter for fremstilling av forbindelser med den generelle formel I:
a) Omsetning av et aminometylpyrrolidin-2-on med den generelle formel
hvor
og R2har de ovenfor angitte betydninger, med et isocyanat med den generelle formel
hvor
R^har de ovenfor angitte betydninger, med unntak av hydroksyalkyl-betydningen; idet man etter denne fremgangsmåte oppnår forbindelser med den generelle formel I, hvor R^står for hydrogen.
b) Omsetning av en forbindelse med den generelle formel II med et klorkarbonylamid med den generelle formel
hvor
R^har de i krav 1 angitte betydninger, med unntak av hydroksyalkyl-betydningen, og R^ har de i krav 1 angitte betydninger, med unntak av hydrogen-betydningen.
c) Omsetning av en forbindelse med den generelle formel II med en klorkarbonsyreester med den generelle formel
hvor
Y er en alkylrest med 1-4 karbonatomer, en benzyl-, fenyl-eller p-nitrofenyl-rest, til et karbamat med den generelle formel
hvor
R^ , R 2 og Y har de ovenfor angitte betydninger.
Karbamatet VI reagerer med et amin med den generelle formel
hvor
R^og R^har de angitte betydninger, til detønskede sluttprodukt . d) Et sluttprodukt med den generelle formel I, hvor R2og/eller R^står for hydrogen, kan alkyleres på vanlig måte.
Syntesene a) og b) foretas i inerte, vannfrie oppløsnings-midler som dioksan, tetrahydrofuran, dimetylformamid, eter, benzen, toluen, klorerte hydrokarboner osv. ved temperaturer mellom 0°C og reaksjonsblandingens kokepunkt, fortrinnsvis ved romtemperatur.
Omsetningen av en aminoforbindelse med formel II med et isocyanat med formel III kan også foretas uten oppløsningsmiddel. For fremgangsmåte b) anbefales tilsetning av et syrebindende middel, f. eks. en organisk base som trietylamin eller pyridin, eller et alkalikarbonat.
Totrinns-syntesen c) utføres i det første trinn, omsetningen av et amin II med en klorkarbonsyreester V, like-ledes i et av de ovenfor angitte, vannfrie, inerte oppløsnings-midler ved temperaturer mellom 0°C og reaksjonsblandingens kokepunkt.
Reaksjonen mellom et intermediært dannet karbamat med formel VI og et amin med formel VII foregår i vannfrie, inerte oppløsningsmidler, eksempelvis de ovenfor angitte, eller med et overskudd av aminet VII ved temperaturer mellom 0°C og romtemperatur eller noe høyere temperatur. Ved lavtkokende aminer er bruk av autoklav hensiktsmessig. Under reaksjonen kan det være hensiktsmessig å tilsette en tertiær organisk base for å fange opp fenolene som dannes.
Alkyleringen nevnt under d) skjer på vanlig måte ved salt-dannelse i ureagruppen ved hjelp av natriumhydrid eller natrium-metylat og påfølgende omsetning med et alkylhalogenid eller
dialkylsulfat.
De nye forbindelsene med den generelle formel I er i besittelse av et asymmetrisentrum og foreligger derfor som racemater. Racematene kan på kjent måte, f. eks. ved salt-dannelse med optisk aktive syrer, overføres i de tilsvarende diastereomerer som så kan overføres i de optisk aktive sluttprodukter .
De optisk aktive sluttproduktene oppnås også direkte fra de optisk aktive aminoalkylforbindelsene med formel II.
Fremgangsmåter for fremstilling av utgangsstoffene, 4-aminometylpyrrolidinoner med den generelle formel II, er beskrevet i tysk patentsøknad P 33 36 024.3. Forbindelsene kan eksempelvis oppnås ved å gå ut fra 4-cyanometylamino-pyrrolidinon-(2) med en passende substituent på nitrogenatomet og hydrere disse på vanlig måte.
Etter de ovennevnte fremgangsmåter kan eksempelvis følgende sluttprodukter oppnås: 4-(metylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(isopropylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(N,N-dimetylaminoetylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(cykloheksylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(m-klorfenylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(N-nortropanyl-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(N-morfolino-karbonylaminometyl)-1-(p-metoksybenzyl)-pyrrolidin-2-on,
4-(N-metylpiperazinyl-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(N-metylpiperazinyl-karbonylaminometyl)-1-(p-metylbenzyl)-pyrrolidin-2-on,
4-(2,6-dimetylmorfolino-karbonylaminometyl)-1 -(p-metylbenzyl)-pyrrolidin-2-on,
4-(N-metylpiperazinyl-karbonylaminometyl)-1-(o-klorbenzyl)-pyrrolidin-2-on,
4-(N-metylpiperazinyl-karbonylaminometyl)-1-(p-fluorbenzyl)-pyrrolidin-2-on,
4-(N-metylpiperazinyl-karbonyl-N1-metyl-aminometyl)-1 - benzylpyrrolidin-2-on,
4-(N-metylpiperazinyl-karbonyl-N<1->isopropyl-aminometyl)-1-benzylpyrrolidin-2-on,
4-(N-dimetylamino-karbonyl-N'-isopropylamino)-1-benzylpyrrolidin-2-on,
4-(dimetylamino-karbonyl-N<1->isopropyl-aminometyl)-1-benzylpyrrolidin-2-on,
4-(morfolino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(piperazino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-[N-(p-klorfenyl)-piperazino-karbonylaminometyl]-1-benzylpyrrolidin-2-on,
4-(piperidino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(3-hydroksyetylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(p-klorfenylamino-karbonylaminometyl)-1-benzylpyrrolidin-2-on,
4-(N-benzylpiperazinyl-karbonylaminometyl)-1-benzylpyrrolidin-2-on.
De nye pyrrolidinon-derivatene er blitt undersøkt dyreeksperimentelt med henblikk på å oppheve eller minske tilstander av begrenset cerebral prestasjonsevne.
Det viste seg at forbindelsene binder seg med høy affinitet til muskarin-kolinerge reseptorstrukturer i rotte-cortex.
I undersøkelser av sentralaktivering ble det under på-virkning av de nye forbindelser på katt ved hjelp av EEG, funnet en desynkronisasjon (vekke-resp. våkne-reaksjon). Dette kunne medføre en ønsket sentralstimulerende virkning hos mennesker, spesielt under det sykdomsbilde som sees ved nedsatt kolinerg overførsels-funksjon (Alzheimer<1>s sykdom).
I orienterende forlikelighetsundersøkelser på mus viser forbindelsene i doseringer opp til 2 g/kg (engangs applikasjon per os) ingen akutt toksisitet (14 dagers etterobservasjon). Dyreeksperimentelt gir de utmerkede virkninger på spontane kognitive prestasjoner, så som eksperimentelle begrensede lære- og huske-prosesser. I forsøk med nedsettelse av korttids-hukommelsen, respektivt hindring av overgang av innhold i korttids- til langtids-hukommelsen ved administrasjon av en muskarin-kolinerg antagonist (scopolamin 0,6 mg/kg i.p.; se også Psychopharmacology, 78.'104-1 1 1 (1982)), er forbindelsene i stand til å motvirke, eventuelt oppheve, denne farmakologisk induserte cerebrale insuffisiens.
Innlæringsevnen hos rotter i en aktiv unngå-dressur
(J. pharmacol. Methods, 8, 255-263 (1983) forbedres, likeså dyrenes vanemessige, respektivt eksplorerende, orienterings-aktivitet i nye omgivelser.
Ved testing av overlevelsesevne i et lukket kammer (hypoksi-tolerans test), gjennomstrømmet med en gassblanding bestående av 96,5 % N2og 3,5 % 02, oppviste dyrene behandlet med de nye forbindelser, en statistisk høysignifikant høyere overlevelsesevne enn kontrolldyr, respektivt dyr behandlet med eventuelt "Pirazetam". Dessuten var den hjernebeskyttende virkning av forbindelsene, ved undersøkelse etter denne metode, utpreget allerede ved en dosering på 100 mg/kg p.o.
De nye pyrrolidinon-derivatene er sammenlignet med ander-ledes strukturerte pyrrolidinoner, som allerede finner anvendelse (Pirazetam), resp. utprøves klinisk (Anirazetam), i forbindelse med cerebral insuffisiens, resp. det hjerneorganiske psykodrom, ved posttraumatiske og alkoholforårsakede hjerne-skader, osv.
De nye forbindelsene er de nevnte forbindelser klart overlegne både med hensyn til virksom dose og med hensyn til oppnådde prestasjonsforbedringer i dyreforsøkene.
De nye forbindelsene kan benyttes enten alene eller som
en kombinasjon av flere, eventuelt også i kombinasjon med andre farmakologisk aktive virkestoffer, f. eks. andre cerebro-aktivatorer. Egnede doseringsformer er for eksempel tabletter, kapsler, pastiller, oppløsninger, safter, emulsjoner eller dispergerbare pulvere. Tabletter kan oppnås ved blanding av virkestoffene med kjente hjelpestoffer, eksempelvis inerte
fortynningsmidler, så som kalsiumkarbonat, kalsiumfosfat eller melkesukker, sprengmidler, som maisstivelse eller alginsyre, bindemidler som stivelse eller gelatin, glattemidler, som magnesiumstearat eller talkum, og/eller med midler for å
oppnå depot-effekter, som f. eks. karboksypolymetylen, karboksy-metylcellulose, celluloseacetatftalat eller polyvinylacetat.
Tablettene kan også bestå av flere sjikt.
Tilsvarende kan drasjeer fremstilles av kjerner fremstillet analogt med tablettene ved at de overtrekkes med et vanlig anvendt middel for formålet, eksempelvis kollidon eller skjell-lakk, gummi arabikum, talkum, titandioksyd eller sukker. For å oppnå en depot-effekt eller hindre uforlikelighet, kan kjernen også bestå av flere sjikt. Drasjeringen kan bestå av flere sjikt for å oppnå en depot-effekt og i så fall kan hjelpe-stoffene nevnt under tabletter, benyttes.
Safter av virkestoffene fremstillet i henhold til oppfinnelsen, eventuelt virkestoffkombinasjoner, kan dessuten inneholde et annet søtningsmiddel som sakkarin, cyklamat, glycerol eller sukker, samt smaksforbedrende midler, f. eks. aromastoffer som vanillin eller appelsinekstrakt. De kan dessuten inneholde suspenderingshjelpestoffer eller fortyknings-midler, som natriumkarboksymetylcellulose, fuktemidler, f. eks. kondensasjonsprodukter av fettalkoholer med etylenoksyd, eller beskyttelsesstoffer, som p-hydroksybenzoat.
Injeksjonsoppløsninger fremstilles på vanlig måte, f. eks. under tilsetning av konserveringsmidler, som p-hydroksy-benzoater, eller stabilisatorer, som alkalisalter av etylen-diamintetraeddiksyre, og fylles så over på injeksjonsglass eller ampuller.
Kapsler med ett eller flere virkestoff, eventuelt virkestoffkombinasjoner, kan eksempelvis fremstilles ved at virkestoffene blandes med inerte bæremidler, som melkesukker eller sorbitt, og innkapsles i gelatinkapsler.
Egnede pastiller lar seg eksempelvis fremstille ved å blande bæremidler beregnet til formålet med nøytralt fett eller polyetylenglykol, resp. derivater av sistnevnte.
