Oppfinnelsen vedrører analogifremgangsmåte til fremstilling av heteroarylbenzoksepin-eddiksyrer, estere og farmasøytisk tålbare salter herav med antiinflammatorisk og analgetisk aktivitet.
Svovelforbindelser med formel:
og derivate herav omtales som å ha analgetiske, antipyretiske og antiinflammatorisk aktivitet i japansk patent nr. 72 00 425, I US-patentsøknad,userial nr. ^59 -77^ av 10.4.74, omtaler 6,11-[h,eloksepin-eddiksyre og derivater herav viser antiinflammatorisk og analgetisk aktivitet. De tricykliske forbindelser ifølge oppfinnelsen har en klar strukturforskjell og utøver god aktivitet. Oppfinnelsen vedrører analogifremgangsmåte fojs fremstilling av forbindelser med terapeutiske egenskaper og med formel hvori R betyr hydrogen eller et C^-C^-alkylradikal og Z betyr en av de følgende heteroaryl ringstrukturér idet fremgangsmåten er karakterisert ved at det cykliseres en forbindelse med formel
hvori Z har ovennevnte betydning og X betyr halogen eller hydroksy og hvis X betyr halogen, hydrolyseres den dannede forbindelse, eventuelt forestres den dannede forbindelse, for å innføre radikalet R.
Som velkjent for fagfolk på området avstemmes reaksjonstidene med reaksjonstemperaturene, således at kortere tider kreves når det benyttes høyere temperatur.
De tricykliske forbindelser fremstilt ifølge oppfinnelsen er nyttige som systemiske antiinflammatoriske stoffer på grunn av deres evne til å undertrykke inflammasjoner hos pattedyr.
De tricykliske forbindelser fremstilt ifølge oppfinnelsen er også anveridelige som topiske antiinflammatoriske midler på grunn av deres evne til å undertrykke dermalinflamma-sjon hos pattedyr og videre som analgetiske stoffer, for på grunn av deres- evne til å lindre smerte hos pattedyr.
Forbindelsene ifølge oppfinnelsen er nyttige som systemiske antiinflammatoriske og/eller analgetiske stoffer ved en dose fra 0,1-50 mg/kg legemsvekt og som topiske anti-inf lammatoriske stoffer ved konsentrasjoner fra 0,1-20?.
Effektive mengder av de tricykliske forbindelser fremstilt ifølge oppfinnelsen kan administreres til en pasient ved hjelp av flere metoder, f.eks. oralt som kapsler eller
tabletter, topikalt som omslag, oppløsninger eller salver, parenteralt.i form av sterile oppløsninger eller suspensjoner og i noen tilfeller intravenøst, i form av sterile oppløsninger. Det frie syresluttprodukt, enskjønt effektivt i seg selv,
kan formuleres og administreres i form av deres farmasøytisk godtagbare addisjonssalter med hensyn til stabilitet, krystalli-
sering, øket oppløselighet og lignende. Slike, salter innbefatter disse av natrium, kalium, kalsium, magnesium eller ammonium.
Oppfinnelsen skal forklares nærmere ved hjelp av noen eksempler.
