Description
Analogifremgangsmåte for fremstilling av farmakologisk, særlig hypoglycemisk virksomme N1-isoindolin-N-benzen-sulfonylcarbamid-er.
Nærværende oppfinnelse vedrorer en analogifremgangsmåte for fremstilling av nye derivater av N-arylsulfonyl-N'-(isoindolin-2)-carbamider med den generelle formel:
hvor X betegner
-et hydrogenatom
-et halogenatom
-et metyll-, etyll- eller metylloxyradikal;
og A betegner et cyklisk hydrokarbon fra gruppen omfattende benzen, cyklohexan, endometylen-cyklohexan, endoxo-cyklohexan, cyklohexen, metyll-cyklohexen og endometylen-cyklohexen, så vel som salter av disse derivater med forenbare syrer og baser.
I de franske patenter nr. 1 3<1>+5 329 og 1 357 285 er beskrevet derivater med hypoglycemisk virkning, i det forste patent benzen-sulfonyl semicarbasider og i det annet patent benzen-sulfonyl tiosemicarbasider. I sammenligning med disse kjente forbindelser har forbindelsene som fremstilles ifolge nærværende oppfinnelse en langt sterkere hypoglycemisk virkning.
Ifolge nærværende oppfinnelse fremstilles forbindelsene med formel I ved å omsette et benzen-sulfonyl—uretan med et N-amino-isoindolin etter den metode som er beskrevet av Marshall og medarbeidere i J. Org.Chem. 23_, 927 (1958), idet N-amino-isoindolinet med formelen: hvor A har foran angitte betydning, omsettes med et benzensulf onyl -uretan med formelen:,
hvor X har foran angitte; betydning.
Utgangsforbindolsen N-amirio-isoindolin kan fremstilles ved an-vendelse av metoden av W. Baker og medarbeidere (J. Chem. Soc. 2971 (19^1)), sorn omfatter nitrosering av et isoindolin og reduksjon av N-nitroso-isoindolinet som dannesfmed lithium-alumi nium-hydr i d.
Derivatene som oppnås ifolge oppfinnelsen kan lett erholdes i form av deres addi .<;jonssaltcr enten med egnede syrer eller med baser. Blandt syror som anvendes kan nevnes: saltsyre, brom-hydrogensyre, sulfonsyre, oddiksyre, malonsyre, maleinsyre, fumarsyre, maursyre, eplesyre og andre. Blandt baser kan nevnes hydroxyder av alkali- og jordalkalimetaller, amino-alkoholer' som i'.eks. l-arnino-propanol-2,2-amino-2-metyll-propanol-1 og cholin.
Disse nye derivater og deres addisjonssalter er i besiddelse av viktige terapeutiske egenskaper, særlig hypoglycemiske egenskaper og de kan anvendes som legemidler ved behandling av sukkersyke sammen med egnede farmasøytiske bærestoffer.
Giftigheten for de nye isoindolinsulfonylcarbamider er meget liten. Når mus administreres oralt med 3 g/kg av de nye derivater, iakttaes ingen dodelighet ilopet av KQ timer.
Den hypoglycemiske aktivitet har vært undersokt på rotter og kaniner med doser på 10-25 mg/kg. En betydelig blodsukkersenkning ble oppnådd med alle derivater og utgjorde opp til 53% med 10 mg/kg hos kaniner, og opp til 38% med 25 mg/kg hos rotter.
Til sammenligning forårsaker det velkjente og klinisk meget an-vendte hypoglycemiske "Tolbutamid" med en dose på 25 mg/kg bare en blodsukkersenkning på 19% hos kaniner og 50 nig/kg er nod-vendig for å oppnå en blodsukkersenkning på 23% hos rotter.
De folgende eksempler illustrerer oppfinnelsen. Alle deler er vektsdeler og smeltepunkter er bestemt ved KoTler-metoden.
Eksempel 1
N- (^-- motyll- benzensul (' onyl) - N' - ( isoindolin- 2) - carbamid
Til en suspensjon inneholdende 12,2 deler '(--motyll-benzen-sulfonyluretan og 22 deler toluon tilsettes hurtig 6,7 deler N-amino-isoindolin og 22 deler toluon. I lopet av noen Tå minutter omdannes blandingen til en oppløsning. Opplesningen oppvarmes under tilbakelbp i 2 timer. Don erholdte klare opp-losning krys talliseres ved avkjolning. Krystallene 1'iltreres, vaskes med 8 deler toluon og omkrystalli seres deretter med vannfri othanol.
Det erholdes 9 deler av produktet som smelter ved 198-199°C.
