Description
Analogifremgangsmåte til fremstilling av dietyl-cc-(2-dibenzofuranyl)-malonat med terapeutisk virkning.
Foreliggende oppfinnelse vedrorer en fremgangsmåte til fremstilling av dietyl-a-(2-dibenzofuranyl)-malonat med terapeutisk virkning og med formelen:
Fremgangsmåten til fremstilling av denne forbindelsen består i å opp-varme etyl-2-dibenzofuranylacetat sammen med 1 - 1.5 ekyimolekylær mengde natriumetoksyd opplost i et ekvimolekylært overskudd av dietylkarbonat.
Fra belgisk patent nr. 658 723 er det kjent arylsubstituerte derivater av organiske syrer, og disse derivater har anti-inflamma-torisk aktivitet. Forbindelsen fremstilt ifolge oppfinnelsen, som om-fatter én heterocyklisk ringstruktur, har også vist seg å ha anti-inf lammatorisk virkning.' Denne virkning kunne ikke forutsees ut fra kjennskapet til det belgiske patent, da den kjemiske struktur av de to typer forbindelser skiller seg vesentlig fra hverandre.
Den betennelseshemmende aktivitet ble bestemt på grunnlag av det velkjente forsok med carrageenin-indusert odem. Til forsokene ble det anvendt hunrotter av Wistar-stammen med en vekt mellom 120 og I50 g, og forbindelsen ble administrert ad oral vei, suspendert i en 10% akacie-gummiopplosning, i forskjellige doser.
Den anti-inflammatoriske aktivitet ble senere bekreftet ved hjelp av forsoket med granuloma-pellets. Det ble anvendt Wistar-rotter, idet to bomullspellets ble anbragt under huden og forsoket ble utfort på grupper av 7 dyr for hver dose. Forbindelsen ble administrert oralt, suspendert i en 0. 5% vandig opplosning av "Methocel",
og behandlingen strakk seg over 6 dager.
De oppnådde resultater er gitt i folgende tabell sammen med LD^q-verdien hos mus, og resultatene ansees som spesielt gunstige i . betraktning av legemidlets lave toksisitet.
Det ble oppnådd utmerkede resultater ved behandlingen av enkelte hud-sykdommer slik som eksem og allergisk dermatitis, ved bruk av salver inneholdende fra 0.1 til 1 g av det aktive legemiddel blandet med vanlige farmasøytiske bærere. Forbindelsen ble funnet å være meget effek-tiv ved helbredelse av sykdommer som reumatisk feber, kronisk reumatisk leddgikt, reumatismelignende leddbetennelse og podagra, og de vanlige former for administrering, dvs. oral, intramuskulær og rektal administrering ga tilfredsstillende resultater. Den daglige dose varierer fra 0.1 til 0.9 g.
Folgende eksempel illustrerer oppfinnelsen.
Eksempel Fremstilling av dietyl- a-( 2- dibenzofuranyl)- malonat.
8.6 g natrium opploses i 240 ml vannfri etanol, og opplosningsmidlet avdestilleres deretter på et oljebad. Natriumetoksyd-resten opploses i 25O ml dietylkarbonat, og deretter tilsettes lang-somt en opplosning av 69 g etyl-2-dibenzofuranylacetat i 25O ml dietylkarbonat, i lopet av 2 1/2 time. Temperaturen i badet heves til 150°C inntil opplosningsmidlet er fullstendig fjernet. Blandingen helles deretter i isvann, surgjbres med saltsyre og ekstraheres med dietyl-eter. Eterekstraktene torkes over natriumsulfat og konsentreres til torrhet. Resten omkrystalliseres fra isopropyleter og gir 6.7 g dietyl- a- (2-dibenzof uranyl ) -malonat med smeltepunkt 84.5°- 85°C.
Analyse: Beregnet for C^H^O^: C 69.92; H 5.56
Funnet: C 70.11; H 5.39.
