Description
Bakgrunn for oppfinnelsen
Foreliggende oppfinnelse angår en fremgangsmåte for fremstilling av nye hydroksamsyre- og N-hydroksyurinstoff-derivater og deres anvendelse. Forbindelsene fremstilt ifølge oppfinnelsen hemmer virkningen av lipoksygenase-enzym og er nyttige for behandling av inflammatoriske sykdommer eller tilstander generelt, f.eks. allergier og kardiovaskulære sykdommer hos pattedyr, innbefattet mennesker.
Arachidonsyre er kjent for å være den biologiske forløper for flere grupper endogene metabolitter, prostaglandiner innbefattet prostacykliner, tromboksaner og leukotriener. Det første trinn i arachidonsyre-metabolisme er frigjøring av forestret arachidonsyre og beslektede umettede fettsyrer fra membran-fosfolipider via virkningen av fosfolipase. Frie fettsyrer metaboliseres derefter enten ved cykloksygenase for å produsere prostaglandiner og tromboksaner eller ved lipoksygenase for å danne hydroperoksy-fettsyrer som kan omdannes videre til leukotriener. Leukotriener har vært implisert i patofysiologien til inflammatoriske sykdommer, innbefattet reumatoid artritt, gikt, astma, ischemi reperfusjons-skade, psoriasis og inflammatorisk tarm-sykdom. Ethvert legemiddel som hemmer lipoksygenase forventes å gi betydningsfull ny terapi både for akutte og kroniske inflammatoriske tilstander.
I det senere er flere oversiktsartikler vedrørende lipoksygenase-inhibitorer blitt angitt. Se f.eks. H. Masamune and L. S. Melvin, Sr., i Annual Reports in Medicinal Chemistry, 24, 71-80 (Academic Press, 1989) og B. J. Fitzsimmons and J. Rokach i Leukotrienes and Lipoxygenases, 427-502 (Elsevier, 1989) .
Videre beskriver EP 279.263 A2, EP 196.184 A2, JP 63502179 og US patent 4.822.809 lipoksygenase-inhibitorer.
Oppfinnerne har arbeidet for å fremstille forbindelser som er i stand til å hemme virkningen av lipoksygenase, og efter utstrakt forskning, har de lykkes i å syntetisere en serie forbindelser som er beskrevet i detalj i her.

Detaljert beskrivelse av oppfinnelsen
Betegnelsen "halogen" som anvendt her, betyr fluor, klor, brom eller jod.
Betegnelsen "cykloalkyl" som anvendt her betyr en cyklisk gruppe med 4 til 8 karbonatomer, så som cyklopropyl, cyklo-butyl, cyklopentyl og cykloheksyl.
Betegnelsen "alkyl" omfatter rettkjedet eller forgrenet.
Betegnelsen "farmasøytisk godtagbart kation" som anvendt her betyr ikke-toksiske kationer, innbefattet slike av alkali-og jordalkalime.taller så som natrium, litium, kalium, kalsium og magnesium, og organiske kationer basert på ammonium-forbin-
deiser og aminer.
Noen av forbindelsene med formel I kan danne syreaddisjonssalter. De farmasøytisk godtagbare syreaddisjons-saltene er de som dannes fra syrer som danner ikke-toksiske syreaddisjonssalter, f.eks. hydroklorid-, hydrobromid-, sul-fat- eller bisulfat-, fosfat- eller syrefosfat-, acetat-, citrat-, fumarat-, glukonat-, laktat-, maleat-, succinat-, tartrat-, metansulfonat-, benzensulfonat-, toluensulfonat- og forimat-salter.
Forbindelsene fremstilt ifølge foreliggende oppfinnelse kan anvendes i farmasøytiske preparater for behandling av inf lammatoriske sykdommer'/.allergier og kardiovaskulære sykdommer hos pattedyr. Slike preparater omfatter en farmasøy-tisk godtagbar bærer eller fortynningsmiddel og en forbindelse med formel I eller et farmasøytisk godtagbart salt derav.
De farmasøytiske preparater kan også anvendes for å hemme virkningen av lipoksygenase-enzym i pattedyr.
Fremgangsmåten ifølge oppfinnelsen for fremstilling av forbindelsene med formel I kjennetegnes ved
(I) når.R<1> er Cl til C4 alkyl,
(A) fremstilling av et diacyl med formelen
fra et hydroksylamin med formelen hvor Q betyr ved omsetning av hydroksylaminet med acylklorid eller acylanhydrid, med en base i et ikke-reaktivt oppløsningsmiddel; (B) isolering av diacyl-forbindelsen; (C) selektiv hydrolyse av diacyl-forbindelsen ved omsetning med en base for å fremstille forbindelsen; og (D) isolering av forbindelsen;
idet "acyl" er R<1>CO; eller
(II) når R<1> er amino,
(A) behandling av et hydroksylamin med formelen
hvor Q er som under (I),
med trimetylsilylisocyanat i et ikke-reaktivt opp-løsningsmiddel ; og
(B) isolering av forbindelsen; eller
(C) behandling av et hydroksylamin med formelen
hvor Q er som under (I),
med gassformig hydrogenklorid i et ikke-reaktivt oppløsningsmiddel; (D) påfølgende behandling med fosgen og vandig ammoniakk; og
(E) isolering av forbindelsen.
Ved en utførelsesform av alternativ (I) fremstilles
forbindelser med formel IV i henhold til reaksjons-trinnene angitt i Skjema 1 nedenfor.
I trinn 1 fremstilles diacetyl-forbindelsen (III) ved standard metoder kjent innen teknikken. F.eks. omsettes hydroksylaminet (II) med acetylklorid eller eddiksyreanhydrid i et reaksjonsinert oppløsningsmiddel i nærvær av en egnet base. Foretrukne baser er trietylamin og pyridin. Egnede reaksjons-inerte oppløsningsmidler omfatter metylenklorid, kloroform, tetrahydrofuran, benzen og toluen. Omsetningen utføres vanligvis i et temperaturområde fra 0°C til omgivelsestemperatur. Reaksjonstider fra 30 minutter til noen få timer er vanlig. Produktet kan isoleres og renses ved konvensjonelle metoder, f.eks. omkrystallisering eller kromatografi.
Trinn 2 omfatter selektiv hydrolyse av diacetyl-forbindelsen (III) med en egnet base. Baser som hensiktsmessig anvendes ved denne omsetning omfatter ammoniakk, ammonium-hydroksyd, natriumhydroksyd, kaliumhydroksyd og litium-hydroksyd, fortrinnsvis i metanol, etanol, isopropylalkohol eller vann, selv om binære oppløsningsmiddel-systemer så som alkohol-vann, tetrahydrofuran-vann og lignende kan anvendes. Reaksjonstemperaturer er vanligvis i området fra -10°C til omgivelsestemperatur, og reaksjonen er vanligvis fullstendig i løpet av noen få minutter til flere timer. Produktet, som har strukturen vist ved formel IV, isoleres ved standard metoder, og rensning kan oppnås ved konvensjonelle metoder, f.eks. ved omkrystallisering og kromatografi.
Ved en utførelsesform av alternativ (II) fremstilles forbindelser med formel V som illustrert i reaksjonsskjema 2 nedenfor.
Ved dette trinnet behandles hydroksylaminet (II) med trimetylsilylisocyanat i et reaksjons-inert oppløsningsmiddel, vanligvis ved omgivelsestemperatur til tilbakeløpstemperatur. Egnede oppløsningsmidler som ikke reagerer med reaktantene og/eller produktene omfatter f.eks. tetrahydrofuran, dioksan, metylklorid og benzen. En alternativ metode anvender behandling av hydroksylaminet (II) med gassformig hydrogenklorid i et reaksjons-inert oppløsningsmiddel så som benzen eller toluen og derefter påfølgende behandling med fosgen. Reaksjonstemperaturene er vanligvis i området fra omgivelsestemperatur til oppløsningsmidlets kokepunkt. Mellomprodukt-karbamoylkloridet isoleres ikke, men underkastes (f.eks. in situ) omsetning med vandig ammoniakk. Det således oppnådde produkt, som har strukturen vist ved formel V, isoleres ved standard metoder, og rensning kan oppnås ved konvensjonelle metoder så som omkrystallisering og kromatografi.
Det. ovennevnte hydroksylamin (II) fremstilles lett ved standard synteser fra lett tilgjengelige karbonyl-forbindelser, f.eks. ketoner eller aldehyder, eller fra alkoholer eller halogen-forbindelser. F.eks. omdannes en egnet karbonyl-forbindelse til dens oksim og reduseres derefter til det nødvendige hydroksylamin (II) med et egnet reduksjonsmiddel (se f.eks. R. F. Borch et al., J. Am. Chem. Soc, 93, 2897
(1971). Foretrukne reduksjonsmidler omfatter natriumcyano-borhydrid og boran-komplekser så som bor-pyridin, bor-trietylamin og bordimetylsulfid. Trietylsilan i trifluoreddiksyre kan også anvendes.
Alternativt kan hydroksylaminet (II) fremstilles ved
behandling av den tilsvarende alkohol med N,O-bis(tert-butyloksy-karbonyl)hydroksylamin under Mitsunobu-type reaksjonsbetingelser fulgt av syrekatalysert hydrolyse av det N,O-beskyttede mellomprodukt (se JP 1045344). Det kan også være verd å legge merke til at N,O-diacetyl-forbindelsen (III) kan fremstilles under anvendelse av N,O-diacetylhydroksylamin istedenfor N,O-bis(tert-butyloksy-karbonyl)hydroksylamin, og således gir en hensiktsmessig vei til produktet med formel IV.
Det ovennevnte hydroksylamin (II) kan også fremstilles fra en egnet halognid-forbindelse ved omsetning med 0-beskyt-tet hydroksylamin og påfølgende avbeskyttelse (se W. P. Jack-son et al., J. Med. Chem., 31, 499 (1988)). Foretrukne 0-beskyttede hydroksylaminer omfatter O-tetrahydropyranyl-, 0-trimetylsilyl- og O-benzylhydroksylamin.
Hydroksylaminet med formel II således oppnådd ved de ovenfor angitte representative fremgangsmåter isoleres ved standard metoder, og rensning kan oppnås ved konvensjonelle metoder, så som omkrystallisering og kromatografi.
De farmasøytisk godtagbare salter av de nye forbindelsene fremstilt ifølge foreliggende oppfinnelse fremstilles lett ved å kontakte forbindelsene med en støkiometrisk mengde av en passende mineral- eller organisk syre enten i vandig oppløs-ning eller i et egnet organisk oppløsningsmiddel. Saltet kan derefter oppnås ved utfelling eller ved avdampning av opp-løsningsmidlet.
Forbindelsene fremstilt ifølge oppfinnelsen hemmer akti-viteten av lipoksygenase-enzymet. Denne inhibering er demon-strert ved et forsøk under anvendelse av rotte-bukhule-resi-dente celler som bestemmer virkningen av forbindelsene på
metabolismen av arachidonsyre.
Ved dette forsøk indikerer noen foretrukne forbindelser lave IC50-verdier, i området 0,1 til 30 piM, med hensyn til lipoksygenase-inhibering. IC5q' som anvendt her, angir den konsentrasjon av test-forbindelsen som er nødvendig for å bevirke en 50% inhibering av lipoksygenase.
Evnen til forbindelsene fremstilt ifølge foreliggende oppfinnelse til å hemme lipoksygenase-enzym gjør dem nyttige til å kontrollere symptomer fremkalt av endogene metabolitter som oppstår fra arachidonsyre hos pattedyr. Forbindelsene er derfor nyttige for å hindre og behandle slike tilstander og sykdommer hvor akkumulering av arachidonsyre-metabolitter er en forårsakende faktor. Eksempler på slike sykdomstilstander omfatter allergisk bronkial astma, hud-sykdommer, reumatisk artritt, osteoartritt og trombose.
Forbindelsene med formel I og deres farmasøytisk godtagbare salter er således av spesiell nytte ved behandling eller lindring av inflammatoriske sykdommer, allergier, kardiovaskulære sykdommer hos mennesker så vel som hemning av lipoksygenase-enzymet.
For behandling av de forskjellige tilstander beskrevet ovenfor, kan forbindelsene med formel I og deres farmasøytisk godtagbare salter administreres til et menneske enten alene eller, fortrinnsvis, i kombinasjon med farmasøytisk godtagbare bærere eller fortynningsmidler i et farmasøytisk preparat, i henhold til standard farmasøytisk praksis. En forbindelse kan administreres ved en rekke konvensjonelle administrerings-veier, innbefattet oralt, parenteralt eller ved inhalering. Når forbindelsene administreres oralt vil doseområdet normalt være fra ca. 0,1 til 20 mg/kg kroppsvekt av individet som skal behandles, pr. dag, fortrinnsvis fra ca. 0,1 til 1,0 mg/kg/dag i enkle eller oppdelte doser. Dersom parenteral administrering er ønsket, er en effektiv dose vanligvis fra ca. 0,1 til 1,0 mg/kg kroppsvekt til individet som skal behandles, pr. dag. I noen tilfeller kan det være nødvendig å anvende doser utenfor disse grenser, eftersom dosen nødvendigvis vil variere efter alder, vekt og respons til den individuelle pasient så vel som efter alvorlighetsgraden av pasientens symptomer og styrken til den spesielle forbindelse som administreres.
For oral administrering kan forbindelsene med formel I og deres farmasøytisk godtagbare salter f.eks. administreres i form av tabletter, pulvere, pastiller, siruper eller kapsler, eller som en vandig oppløsning eller suspensjon. Når det gjelder tabletter for oral anvendelse, omfatter bærere som vanligvis anvendes, laktose og maisstivelse. I tillegg tilsettes normalt smøremidler, så som magnesiumstearat. Når det gjelder kapsler er nyttige fortynningsmidler laktose og tørret maisstivelse. Når vandige suspensjoner er nødvendig for oral anvendelse, blandes den aktive bestanddel med emulgerings-eller suspenderings-midler. Om ønsket kan visse søtnings-og/eller smaksgivende midler tilsettes. For intramuskulær, intraperitoneal, subkutan og intravenøs anvendelse fremstilles normalt injiserbare oppløsninger av den aktive bestanddel, og pH av oppløsningene er hensiktsmessig regulert og bufret. For intravenøs administrering bør den totale konsentrasjon av oppløst stoff kontrolleres for å gjøre preparatet isotonisk.
Foreliggende oppfinnelse illustreres ved de følgende eksempler. Det skal imidlertid forstås at oppfinnelsen ikke begrenses av de spesifikke detaljer i eksemplene. Proton-kjernemagnetiske resonans-spektra (NMR) ble målt ved 270 MHz hvis ikke annet er angitt for oppløsninger i perdeutero-dimetylsulfoksyd (DMSO-dg), og topp-posisjoner er uttrykt i deler pr. million (ppm) nedover fra tetrametylsilan.
