20 Som hydrogenafgivende reduktionsmiddel kan man f.eks. anvende myresyre (Leuckart-Wallach-reaktion).
Myresyren anvendes i stort overskud. Med formaldehyd som carbonylkomponent kan reaktionen gennemføres i vandig opløsning, med ketoner og lidet reaktionsdygtige 25 aldehyder i vandfri myresyre. Reaktionstemperaturerne ligger på mellem 100 og 200°C, og reaktionen skal eventuelt gennemføres i en autoklav.
Som hydrogenafgivende middel kan man også anvende katalytisk fremkaldt hydrogen. På tale som katalysator 30 kommer først og fremmest Raney-nikkel, men man kan også anvende ædelmetalkatalysatorer. Reaktionen gennemføres almindeligvis ved tryk på mellem 80 og 150 atm E^-tryk og ved temperaturer på mellem 70 og 150°C. Som opløsningsmiddel foretrækkes protiske, polære opløsningsmidler, 35 især alkoholer.

O
Som hydrogenafgivende reduktionsmiddel anvendes også alkalimetalcyanoborhydrider, dialkylaminoboraner og alkalimetalborhydrider. Særlig foretrukket ved denne fremgangsmådevariant er anvendelsen af natriumcyano-5 borhydrid.
Reaktionen gennemføres almindeligvis ved stuetemperatur. Det kan imidlertid også være gunstigt at opvarme til tilbagesvalingstemperatur.
Fremgangsmåden gennemføres sædvanligvis i et in-10 different opløsningsmiddel. Selv om der kan anvendes vandfrie, aprotiske opløsningsmidler, såsom tetrahy-drofuran, når reduktionsmidlet er morpholinoboran, anvendes imidlertid almindeligvis et protisk opløsningsmiddel. Egnet som sådant er især en lavere alkanol. Der 15 kan imidlertid også anvendes vand eller en vandig, la vere alkanol, f.eks. vandig methanol eller ethanol, eller andre, vandige opløsningsmiddelsystemer, såsom vandigt dimethylformamid, vandigt hexamethylphosphorsyre-triamid, vandigt tetrahydrofuran eller vandigt ethylen-20 glycoldimethylether.
Fremgangsmåden gennemføres almindeligvis i et pH-værdiområde på fra 1 til 11, fortrinsvis i et pH-værdiområde mellem 4 og 7.
De her omhandlede inhibitorer er egnede som tera-25 peutiske midler ved følgende indikationer:
Præ-diabetes, Gastritis, Obstipation, Caries, infektioner i gastro-intestinal-området, Meteorismus, Flatulens, Hypertension, Atherosclerosis og især Adi-positas. Diabetes og Hyperlipoprotæmi.
30 Til udvidelse af virkningsspektret kan det være anbefalelsesværdigt at kombinere inhibitorer for glyco-sidhydrolaser, som i deres virkning supplerer hinanden, hvad enten det drejer sig om kombinationer af de her omhandlede inhibitorer med hinanden eller kombinationer 35 af de her omhandlede inhibitorer med allerede kendte.

Det kan således f.eks. være hensigtsmæssigt at kombinere de omhandlede saccharase-inhibitorer med allerede kendte amylase-inhibitorer.
Fordelagtige er i mange tilfælde også kombinatio-5 ner af de her omhandlede inhibitorer med kendte, orale antidiabetika (β-cytotrope sulfonylurinstofderivater og/-eller blodsukkervirksomme biguanider) samt med blod-lipidsænkende aktive forbindelser, såsom clofibrat, ni-cotinsyre og cholestyramin.
10 Forbindelserne kan indgives uden fortynding, f.eks. som pulver eller i en gelatinekapsel, eller i kombination med et bærestof i en farmaceutisk sammensætning.
Farmaceutiske præparater kan indeholde en større eller mindre mængde af inhibitoren, f.eks. 0,1-99,5%, 15 i kombination med et farmaceutisk acceptabelt, ikke-tok- sisk, indifferent bærestof, hvorhos bærestoffet kan indeholde et eller flere, faste, halvfaste eller flydende fortyndingsmidler, fyldstoffer og/eller et ikke-toksisk, indifferent og farmaceutisk acceptabelt formulerings-20 hjælpemiddel. Sådanne farmaceutiske præparater forelig ger fortrinsvis i form af doseringsenheder, dvs. fysisk--diskrete enheder, der indeholder en bestemt mængde af inhibitoren, og som svarer til en brøkdel eller en mangedobling af de doser, der er nødvendige til tilvejebring-25 else af den ønskede hæmningsvirkning. Doseringsenhederne kan indeholde 1, 2, 3, 4 eller flere enkeltdoser eller 1/2, 1/3 eller 1/4 af en enkeltdosis. En enkeltdosis indeholder fortrinsvis en tilstrækkelig mængde aktiv forbindelse til opnåelse af den ønskede hæmningsvirkning 30 ved en indgift ifølge et i forvejen bestemt doserings skema med en eller flere doseringsenheder, hvorhos en hel, en halv eller en tredjedel eller en fjerdedel af dagsdosen sædvanligvis indgives til alle hoved- og bimåltider om dagen. Der kan også indtages andre terapeu-35

tiske midler. Selv om doseringen og doseringsskemaet i hvert tilfælde bør afvejes omhyggeligt under anvendelse af en grundig fagmandsbedømmelse og under hensyntagen til patientens alder, vægt og tilstand samt sygdommens 5 art og sværhedsgrad, vil doseringen sædvanligvis ligge i et område mellem ca. 1 til ca. 1 x 104 SIE/kg legemsvægt pr. dag. I mange tilfælde vil man opnå en tilstrækkelig, terapeutisk virkning med en mindre dosis, medens en større dosis vil være nødvendig i andre til-10 fælde.
Oral indgift kan gennemføres under anvendelse af faste og flydende doseringsenheder, såsom pulvere, tabletter, dragées, kapsler, granulater, suspensioner og opløsninger.
15 Pulvere fremstilles ved findeling af forbindel sen til en egnet størrelse og sammenblanding af denne med et ligeledes findelt, farmaceutisk bærestof. Selv om et spiseligt carbonhydrat, såsom stivelse, lactose, saccharose eller glucose, normalt anvendes til dette 20 formål og også kan anvendes her, er det ønskeligt at anvende et ikke-metaboliserbart carbonhydrat, såsom et cellulosederivat.
Sødemidler, smagstiIsætninger, konserveringsstoffer, dispergeringsmidler og farvemidler kan også med- 25 anvendes.
Kapslerne kan fremstilles ved tilberedning af den ovenfor beskrevne pulverblanding og fyldning af allerede fremstillede gelatinekapsler. Til pulverblandingen kan man forud for fyldningsprocessen sætte smøremidler., så-30 som kiselgel, talkum, magnesiumstearat, calciumstearat eller fast polyethylenglycol. Til blandingen kan der ligeledes sættes en desintegrator eller opløsningsformidler, såsom agar-agar, calciumcarbonat eller natrium-carbonat, til forbedring af inhibitorens tilgængelighed 35 ved kapslernes indtagelse.

O
Færdiggørelse af tabletterne sker f.eks. ved fremstilling af en pulverblanding, grov eller finkornet, og tilsætning af et smøremiddel og en desintegrator. Ud fra denne blanding formes tabletter. Der fremstilles en pul-5 verblanding ved blanding af forbindelsen, der er findelt på egnet måde, og et fortyndingsmiddel eller en anden bæreforbindelse tilsættes som beskrevet ovenfor. Der tilsættes eventuelt et bindemiddel, f.eks. carboxymethylcellu-lose, alginater, gelatine eller polyvinylpyrrolidon, en 10 opløsningsforhaler, f.eks. paraffin, en resorptionsaccelerator, såsom et kvaternært salt, og/eller et adsorptionsmiddel, såsom bentonit, kaolin eller dicalciumphosphat. Pulverblandingen kan granuleres sammen med et bindemiddel, såsom sirup, stivelsespasta, akacieslim eller opløs-15 ninger af cellulose- eller polymermaterialer. Dernæst presses produktet gennem en grov sigte. Som alternativ hertil kan man lade pulverblandingen løbe gennem en tabletteringsmaskine og findele de uregelmæssigt formede stykker, der fremkommer, til kornstørrelse. For at de fremkomne 20 korn ikke skal blive hængende i de tabletdannende dyser, kan der sættes et smøremiddel til dem, f.eks. stearin-syre, stearatsalt, talkum, elelr mineralolie. Denne blanding, der er gjort glidedygtig, presses dernæst i tabletform. De aktive forbindelser kan også kombineres med frit-25 strømmende, indifferente bærestoffer og bringes direkte på tabletform under udeladelse af granulat- eller sønderdelingstrinene. Man kan forsyne produktet med et klart eller opakt beskyttelseshylster, f.eks. et overtræk af shellak, et overtræk af sukker eller polymerforbindelser 30 og et poleret hylster af voks. Farvestoffer kan sættes til disse overtræk, for at der kan skelnes mellem de forskellige doseringsenheder.
De tilberedningsformer, der skal indgives oralt, såsom opløsninger, sirup og eliksirer, kan fremstilles i doseringsenheder, således at en bestemt mængde præparat indeholder en bestemt mængde aktiv forbindelse. Sirup
O
10 DK 152753 B
kan fremstilles på den måde, at den aktive forbindelse opløses i en vandig opløsning, der indeholder egnede smagsstoffer. Eliksirer fås under anvendelse af ikke-toksiske, alkoholiske bærestoffer. Suspensioner kan fremstilles ved 5 dispergering af forbindelsen i et ikke-toksisk bærestof. Opløsningsformidlere og emulgeringsmidler, såsom ethoxy-lerede isostearylalkoholer og polyethylensorbitestere, konserveringsmidler, smagsforbedrende tilsætninger, såsom pebermynteolie eller saccharin, kan også tilsættes.
10 Doseringsforskrifter kan angives på kapslen. Der udover kan doseringen være sikret således, at den aktive forbindelse afgives forsinket, f.eks. ved indeslutning af den aktive forbindelse i f.eks. polymerforbindelser eller voks.
15 Virkningen af. forbindelserne med formel (I) på blodglucosespejlet ved et stivelse-belastningsforsøg er blevet undersøgt.
Ved dette belastningsforsøg med kogt stivelse sættes den undersøgte forbindelse i forskellige koncentratio- 20 ner til det af kogt stivelse bestående foder, og til hvert forsøg fodres en gruppe på 6 rotter dermed. 30 minutter efter fodringen bestemmes stigningen i blodglucosespejlet på gængs måde.
Belastningen bestemmes ved sammenligning med en 25 kontrolgruppe på 6 rotter, som fodres med kogt stivelse uden forsøgsforbindelse, og en kontrolgruppe på 6 rotter, som hverken får kogt stivelse eller forsøgsforbindelse.
