Description
Oppfinnelsen angår kinoksalindionderivater og deres legemidler inneholdende disse.
Det er kjent at kinoksalinderivater har affinitet til kiskvalat-reseptorer og på grunn av affiniteten egner seg som legemidler ved behandling av sykdommer i det sentrale nervesys-tem.
De nye forbindelser er kjennetegnet ved at de har formel I
hvori
R<1> betyr - (CH2) -Z, og
R<5>, R6, R<7> og R<8> er like eller forskjellige og betyr hydrogen, halogen, N02, CF3 eller NR<9>R<10>,
hvorved
Z betyr C02R<23>, hvor R<23> er H eller C^-alkyl,
R9 og R1<0> er hydrogen, eller sammen med nitrogenatomet danner en piperidin-, morfolin-, tiomorfolin- eller 2,6-dimethylmorfolin-ring,
så vel som deres isomerer eller farmasøytisk akseptable salter.
Forbindelsene med den generelle formel I omfatter også mulige tautomere former og omfatter E- eller Z-isomerene, eller dersom det foreligger et chiralt senter, racematene eller enantiomerene.
Med alkyl skal det forstås en lineær eller forgrenet alkylrest som eksempelvis methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sek.-butyl, pentyl, isopentyl, hexyl, hvorved C1.4-alkylrester foretrekkes.
Med halogen skal det forstås fluor, klor, brom og jod, spesielt fluor, klor og brom.
Dersom det inneholdes en sur funksjon, er som salter de fysiologisk forenlige salter av organiske og uorganiske baser egnet, som eksempelvis de lett løselige alkali- og jordalkalisaltene, så vel som N-methyl-glukamin, dimethyl-glukamin, ethyl-glukamin, lysin, 1,6-hexadiamin, ethanolamin, glukosamin, sarkosin, serinol, tris-hydroxy-methylaminomethan, aminopropandiol, Sovak-base, l-amino-2,3,4-butantriol. Dersom det inneholdes en basisk funksjon, er de fysiologisk forenlige salter av organiske og uorganiske syrer egnet, som HC1,
H2S04, fosforsyre, sitronsyre, vinsyre etc.
En særlig foretrukket forbindelse er 1-[6-trifluormethyl-7-[piperidin-l-yl]kinoksalin-2,3-dion)-1-yl]eddiksyre.
Forbindelsene med formel I så vel som deres fysiologisk forenlige salter, er på grunn av deres affinitet til AMPA-reseptorene anvendbare som legemidler. På grunn av deres virkningsprofil egner forbindelsene ifølge oppfinnelsen seg for behandling av sykdommer som forårsakes av stimulerende aminosyrers hyperaktivitet som for eksempel glutamat eller aspartat. Da de nye forbindelser virker som antagonister mot stimulerende aminosyrer og viser en høy spesifikk affinitet til AMPA-reseptorene, idet de fortrenger den radioaktivt markerte, spesifikke agonist (RS) a-amino-3-hydroxy-5-methyl-4-isoxazolpropionat (AMPA) fra AMPA-reseptorer, egner de seg spesielt for behandling av slike sykdommer som påvirkes via reseptorene for stimulerende aminosyrer, spesielt AMPA-reseptorer.
Forbindelsene kan anvendes ved behandling
av neurologiske og psykiatriske forstyrrelser, som
utløses ved overstimulering av AMPA-reseptorer. Til de neurologiske sykdommer som kan behandles funksjonelt og pre-ventivt, hører for eksempel neurodegenerative forstyrrelser somjParkinson1s sykdom, Alzheimer's sykdom, Chorea Huntington, amyotrof lateral sklerose og olivopontocerebellar degenerasjon. Ifølge oppfinnelsen kan forbindelsene anvendes for å hindre det postischemiske celleforfall, celleforfall etter hjerne-trauma, ved slaganfall, hypoksi, anoksi og hypoglykemi og for behandling av senil demens, multiinfarkt demens, så vel som epilepsi og muskelspasme. Til de psykiatriske sykdommer hører angsttilstander, schizofreni, migrene, smertetilstander, så vel som behandling av søvnforstyrrelser og unndragelses-symptomatikk etter medisinmisbruk som ved alkohol-, kokain-, benzodiazepin- eller opiat-unndragelse.
For anvendelse av forbindelsene ifølge oppfinnelsen som legemidler bringes disse i form av et farmasøytisk prepa-rat, som for den enterale eller parenterale applikasjon ved siden av det aktive stoff inneholder egnede farmasøytiske, organiske eller uorganiske, inerte bærermaterialer, som for eksempel vann, gelatin, gummi arabicum, melkesukker, stivelse, magnesiumstearat, talkum, planteolje, polyalkylenglykoler osv. De farmasøytiske preparater kan foreligge i fast form, for eksempel som tabletter, drageer, suppositorier, kapsler eller i flytende form, for eksempel som løsninger, suspensjoner, eller emulsjoner. Eventuelt inneholder de før dette hjelpestoffer som konserverings-, stabiliserings-, fuktemidler eller emulgatorer, salter for forandring av osmotisk trykk eller buffere.
For parenteral anvendelse er spesielt infeksjons-løsninger eller suspensjoner, særlig vannfrie løsninger, av de aktive forbindelser i polyhydroxyethoxylert lakserolje, egnet.
Som bærersystemer kan det også anvendes grenseflate-aktive hjelpestoffer, som salter av gallesyrer eller dyre-eller plantefosfolipid, men også blandinger derav så vel som liposomer eller deres bestanddeler.
For den orale anvendelse er spesielt tabletter, dragéer eller kapsler med talkum og/eller hydrocarbonbærere eller -bindemidler, som for eksempel lactose, mais- eller potetstivelse egnet. Anvendelsen kan også foregå i flytende form, for eksempel som saft, som eventuelt er. tilsatt søte-middel.
Doseringen av de aktive stoffer kan variere avhen-gig av administrasjonsmåte, pasientens alder og vekt, art og alvor av den sykdom som skal behandles og lignende faktorer. Den daglige dose oppgår til 0,5 - 1000 mg, fortrinnsvis 50 - 200 mg, hvorved dosen kan gis som en enkeltdose for éngangs-tilførsel eller opp til én eller flere dagsdoser.
Fremstillingen av forbindelsene ifølge oppfinnelsen foregår ved hjelp av i og for seg kjente fremgangsmåter. Eksempelvis oppnås forbindelsene med formel I derved at
a) en forbindelse med formel II
hvori R 1 til R 8 har den ovenstående betydning, ringsluttes med oxalsyre eller reaktive oxalsyrederivater eller
b) en forbindelse med formel III
hvori R^ har den ovenstående betydning og én av substituentene
51 61 7' 81
R , R , R eller R utgjør en fluktgruppe, substitueres nucleofilt og estergruppen deretter om ønsket forsåpes eller syregruppen forestres eller amideres eller nitrogruppen reduseres til aminogruppe eller aminogruppen alkyleres eller acyleres eller aminogruppen utbyttes mot halogen eller cyano eller en nitrogruppe eller halogen innføres eller en ether-spaltning foretas eller alkoholen overføres til halogenid eller dette halogen substitueres nucleofilt eller et nitril overføres til tetrazolen eller isomerene adskilles eller saltene dannes.
Ringslutningen til forbindelser med formel I foregår med oxalsyre på kjent måte i ett trinn i surt miljø eller med et reaktivt oxalsyrederivat eller også i to trinn. Totrinns-fremgangsmåten er å betrakte som foretrukket, ved hvilken diaminet omsettes med et oxalsyrederivat som for eksempel oxalesterhalvklorid eller reaktive oxalsyreimidazolidderivater i polare løsningsmidler som cykliske eller acykliske ethere eller halogenerte hydrocarboner som for eksempel tetrahydrofuran, diethylether eller methylenklorid i nærvær av en base som organiske aminer, eksempelvis triethylamin, pyridin, i Hunig-base eller dimethylaminopyridin. Den etterfølgende ringslutning kan gjennomføres basisk eller også surt, men fortrinnsvis i surt miljø, hvorved reaksjonsblandingen kan tilsettes alkohol som løsningsformidler.
Egnede baser for totrinns-fremgangsmåten utgjøres også av alkalihydrider, som NaH som tilsettes i inerte løs-ningsmidler som hydrocarboner eller ethere.
Som fluktgrupper i Fremgangsmåtevariant b) så vel
som ved fremstillingen av utgangsforbindelsene med formel II, er halogener som fluor, klor, brom, jod eller O-mes.ylat, O-tosylat, O-triflat eller O-nonaflat egnet. Den nucleofile substitusjon gjennomføres ved hjelp av metoder som er kjent fra litteraturen i nærvær av en base og begunstiges av en aktiverende, elektronuttrekkende gruppe som for eksempel nitro, cyano, trifluormethyl, fortrinnsvis i o-stilling.
Som nucleofiler er eksempelvis primære og sekundære aminer, N-holdige, umettede eller mettede heterocykliske forbindelser, cyanid, alkoholater, thiolater osv. egnet. Omset-ningen kan foregå i molare løsningsmidler som alkoholer, halogenerte hydrocarboner, dimethylacetamid, acetonitril eller vann eller uten løsningsmiddel. Som baser er uorganiske baser som alkali- eller jordalkalihydroxyder eller -carbonater eller organiske baser som cykliske, alicykliske og aromatiske 5 aminer, som DBU, Hiinig-base, pyridin eller dimethylaminopyridin egnet. Som base kan i tilfelle av aminer nucleofilen selv benyttes i overskudd, hvorved det eventuelt kan arbeides uten ytterligere løsningsmiddel. Dersom aminet har for lavt kokepunkt, kan det eventuelt arbeides under trykk i autoklav. 5 Den eventuelt påfølgende forsåpning av en estergruppe kan foregå basisk eller fortrinnsvis surt, idet det hydrolyseres ved forhøyet temperatur opp til reaksjonsblandingens koketemperatur i nærvær av syrer som høykonsentrert, vandig
saltsyre, eventuelt i løsningsmidler som eksempelvis trifluor-o eddiksyre eller alkoholer. Fosfonsyreestere hydrolyseres fortrinnsvis ved oppvarming i høykonsentrerte, vandige syrer som for eksempel konsentrert saltsyre, eventuelt under tilsetning av alkohol eller ved behandling med trimethylsilylhalo-genid i inerte løsningsmidler som for eksempel acetonitril
>5 og etterfølgende behandling med vann.
Forestringen av carboxylsyren eller fosfonsyren foregår på i og for seg kjent måte med den tilsvarende alkohol under syrekatalyse eller i nærvær av et aktivert syrederivat. Som aktiverte syrederivater kommer for eksempel syreklorid, -imidazolid eller -anhydrid på tale. Ved fosfonsyrene kan forestringen oppnås ved omsetning med orthoestere, eventuelt ved omsetning av katalysatorer som p-toluensulfonsyre.
Amideringen foregår på de frie syrer eller på deres reaktive derivater som eksempelvis syreklorider, blandede anhydrider, imidazolider eller azider ved omsetning med de tilsvarende aminer ved romtemperatur.
Reduksjonen av nitrogruppen til aminogruppen foregår katalytisk i polare løsningsmidler ved romtemperatur eller forhøyet temperatur. Som katalysatorer er metaller som Raney-nikkel eller edelmetallkatalysatorer som palladium
eller platina eventuelt på bærere egnet. Istedenfor hydrogen kan det også på kjent måte anvendes ammoniumformiat. Reduk-sjonsmidler som tinn-ll-klorid eller titan-III-klorid kan like-så anvendes, som komplekse metallhydrider, eventuelt i nærvær av tungmetallsalter. Som reduksjonsmiddel er også jern anvend-bart. Reaksjonen gjennomføres da i nærvær av en syre, som for eksempel eddiksyre eller ammoniumklorid eventuelt under tilsetning av et løsningsmiddel som vann. Det kan være for-delaktig å innføre estergruppen før reduksjonen. Ved nærvær av flere nitrogrupper i molekylet kan den ønskede, ortho-stående hitrogruppe også selektivt reduseres med Na2S på vanlig måte.
Dersom det er ønsket med en alkylering av en aminogruppe, kan det alkyleres ifølge vanlige metoder eksempelvis med alkylhalogenider eller ifølge Mitsonubo-varianten ved omsetning med en alkohol i nærvær av trifenylfosfin og azo-dicarboxylsyreester eller aminet underkastes en reduktiv aminering med aldehyder eller ketoner, eventuelt etter hver-andre med to forskjellige carbonylforbindelser, hvorved det oppnås blandede derivater (Litteratur som for eksempel Verardo et al. Synthesis 1993, 121; Synthesis 1991, 447; Kawaguchi, Synthesis 1985, 701; Micovic et al., Synthesis 1991, 1.043).
Acyleringen av en aminogruppe foregår på vanlig måte, eksempelvis med et syrehalogenid eller syreanhydrid, eventuelt i nærvær av en base som dimethylaminopyridin i løsningsmidler som methylenklorid, tetrahydrofuran eller pyridin eller ifølge Scotten Baumann-varianten i vandig løsning ved svakt alkalisk pH-verdi.
Innføringen av cyanogruppen kan foregå ved hjelp av Sandmeyer-reaksjonen. Eksempelvis kan diazoniumsaltene som
er dannet som mellomprodukter fra aminoforbindelsene og nitritter, omsettes med alkalicyanider i nærvær av Cu-I-cyanid.
Innføringen av halogenene klor, brom eller jod via aminogruppen kan eksempelvis også foregå ifølge Sandmeyer idet diazoniumsaltene som er dannet som mellomprodukter med nitrit-tene, omsettes med Cu(I)klorid eller Cu(I)bromid i nærvær av den tilsvarende syre som saltsyre eller bromnitrogensyre eller med kaliumjodid. Når det benyttes en organisk salpetersyre-ester, kan halogenene innføres, for eksempel ved omsetning av methylenjodid eller tetrabrommethan i et løsningsmiddel som for eksempel dimethylformamid.
Innføringen av fluor lykkes eksempelvis ved Balz Schiemann-reaksjonen av diazoniumtetrafluorborater.
Innføringen av en NC^-gruppe lykkes ved hjelp av en rekke kjente -nitreringsmetoder.. Eksempelvis kan det nitre-ires med nitroniumtetrafluorborat i inerte løsningsmidler som halogenerte hydrocarboner eller sul.folan, iseddik eller acetonitril. Mulig er også innføringen f.eks. ved hjelp av nitrér-syre i konsentrert svovelsyre som løsningsmiddel ved temperaturer på mellom 0 og 30° C.
i Innføringen av halogen lykkes ved hjelp av kjente halogeneringsmetoder, som f.eks. med elektrofil, aromatisk substitusjon.
Eksempelvis kan det joderes ved hjelp av en frem-gangsmåte med jod og jodsyre ifølge Wirth et al. [Liebigs Ann. 3Chem. 634, 84 (1960)] eller med N-jodsuccinimid i løsningsmid-ler som tetrahydrofuran, dimethylformamid eller trifluormethan-sulfonsyre.
Etherspaltningen foregår ifølge de vanlige metoder, eksempelvis ved reaksjon med trimethylbromsilan, eventuelt 5 under tilsetning av alkalijodid i et inert løsningsmiddel som acetonitril. ved en temperatur på 0° C til løsningsmidlets koketemperatur.
Innføringen av tetrazoler foregår ved omsetning av det tilsvarende nitril med et azid, som for eksempel trimethyl-silylazid, nitrogen-hydrogensyre eller natriumazid eventuelt under tilsetning av en protonkilde som for eksempel ammoniumklorid eller triethylammoniumklorid i polare løsningsmidler som dimethylformamid, dimethylacetamid eller N-methylpyrrolidon ved temperaturer opp til løsningsmidlets kokepunkt.
Overføringen av alkoholen til halogenidet foregår med syrehalogenider som thionylklorid eller fosfortribromid med eller uten løsningsmidler. Som løsningsmidler er halogenerte hydrocarboner, for eksempel methylenklorid eller ethere mulig.
Isomerblandingene kan adskilles ved hjelp av vanlige metoder som eksempelvis krystallisasjon, kromatografi eller saltdannelse til enantiomerene henholdsvis E/Z-isomerene.
Fremstillingen av saltene foregår på vanlig måte, idet en løsning av forbindelsen med formel I tilsettes den ekvivalente mengde eller et overskudd av en base eller syre, som eventuelt er i løsning, og bunnfallet adskilles eller løsningen opparbeides på vanlig måte.
For så vidt fremstillingen av utgangsforbindelsene ikke beskrives, er disse kjente eller kan fremstilles analogt med kjente forbindelser, eksempelvis ifølge WO93/08171 eller fremgangsmåter som er beskrevet her.
