Den foreliggende opfindelse angår en analogifrerrgangsmåde til fremstilling af hidtil ukendte tiazolidinderivater med hypo-lipidæmisk og hypoglycæmisk virkning samt lav toxicitet. Nærmere bestemt angår den foreliggende opfindelse en analogifremgangsmåde til fremstilling af tiazolidinderivater med den almene formel L1 __.
l2-c-r2-o-^</ V-ch^-ch—c=o
l* / i L
Ύ 12 1 2 hvor R , R , L og L har de i krav l's indledning angivne betydninger, eller farmaceutisk acceptable salte deraf.
I den almene formel 1 kan en alkylgruppe R"*" således være en ligekædet eller forgrenet alkylgruppe med 1-10 kulstofatomer, såsom metyl, ætyl, n-propyl, isopropyl, n-butyl, isobutyl, t-butyl, n-pentyl, isopentyl, n-hexyl, n-heptyl, n-oktyl, n-nonyl eller n-decyl. En cyploalkylgruppe R3, kan være en cykloalkylgruppe med 3-7 kulstofatomer såsom cyklo-propyl, cyklopentyl, cyklohexyl og cykloheptyl. En fenylalkyl-gruppe R1 kan være en fenylalkylgruppe med 7-11 kulstofatomer såsom benzyl og fenætyl. Den heterocykliske gruppe R3- kan være en 5- eller 6-leddet gruppe med et eller to heteroatomer valgt blandt nitrogen, oxygen og svovl, såsom pyridyl, tienyl,' furyl eller tiazolyl. Når R1 er en gruppe med formlen R3 ^'N- kan alkylgrupperne R3 og- R4 hver være en alkylgruppe med 1-4 kulstofatomer, såsom metyl, ætyl, n-propyl, 3 4 isopropyl og n-butyl. Når R og R er forenet til hinanden til dannelse af en 5- eller 6-leddet heterocyklisk gruppe taget sammen med det naboliggende N-atom, dvs. i form af R3 ^ N-R4^ 149023 2 kan denne heterocykliske gruppe yderligere indbefatte et hete-roatom valgt blandt nitrogen, oxygen og svovl, eksemplificeret med piperidino, morfolino, pyrrolidino og piperazino.
o
Alkylengruppen R kan indeholde 1-3 kulstofatomer og kan 2 således fx være metylen, ætylen eller trimetylen. R kan som nævnt betegne en kemisk binding, i hvilket tilfælde den almene formel I repræsenteres med følgende almene formel L1 ______
L2-(!>0-_/r \yjCH„-CH-C=0 II

Y
2 Når R er en binding er dens naboatomer til begge sider således direkte bundet til hinanden.

Alkylgrupperne L og L kan være alkylgrupper med 1-3 kulstofatomer, såsom metyl og ætyl. Den alkylengruppe der dannes ved 1 2 at L og L er bundet til hinanden er en gruppe med formlen ~^CH2^n"’ ^vor n er et helt tal fra 2 til 6). De ovennævnte cykliske grupper, dvs. cykloalkylgruppen, fenylalkylgruppen, fenylgruppen og de heterocykliske grupper såvel som den heterocykliske gruppe med formlen R3 kan have 1-3 substituenter i vilkårlige stillinger i de respektive ringe. Disse substituenter kan vælges blandt metyl, ætyl, metoxy, ætoxy, halogen (fx klor eller brom) og hydroxyl. Inden for rammerne af den almene formel I*s omfang ligger også den mulighed at en metylendioxygruppe er bundet til to naboliggende kulstofatomer på ringen til dannelse af en yderligere ring.
De omhandlede forbindelser kan omdannes til forskellige salte ved i og for sig kendte fremgangsmåder. Fx, når den heterocykliske gruppe R indbefatter et tertiært nitrogenatom, eller R1 er en gruppe med formlen 149023 3 N- kan forbindelsen med formel I omdannes til syresalte med syrer, såsom saltsyre, svovlsyre, eddikesyre eller oxalsyre. Når R^ ikke indbefatter et tertiært nitrogenatom kan forbindelsen omdannes til salte med kationer såsom natriumion, kaliumion, kalciumion eller ammoniumion.
De omhandlede tiazolidinderivater med den almene formel I har sænkende virkning på blodets sukkerniveau og tri-glyceridniveau hos mus (KKAy) med spontan diabetes og de kan forventes at være værdifulde ved behandling af hyperl.ipæmi, diabetes og disse sygdommes ledsagende komplikationer hos pattedyr indbefattet mennesker. Forbindelserne med formel I har lav toxicitet. Fx er LD^q-værdien for 5-[4-(1-metylcyklohexyl-metyloxy)-benzyl]tiazolidin-2,4-dion hos rotter større end 10 g/kg p.o. Forbindelsen I kan indgives oralt i sådanne dosisformer som tabletter, kapsler, pulvere eller granulater, eller ad andre indgiftsveje i sådanne former som injektionsopløsninger, suppositorier eller piller. Idet behandlingen af hyperlipæmi tages som et eksempel kan forbindelsen indgives oralt eller ad anden vej i et normalt dagligt dosisniveau på 50 mg til 1 g til et voksent menneske. Til behandling af diabetes kan forbindelsen med formel I indgives oralt eller på anden måde i en normal daglig dosis på 10 mg til 1 g til et voksent menneske.
Fremgangsmåden ifølge opfindelsen er ejendommelig ved det i krav 1's kendetegnende del anførte og beskrives nærmere i det følgende, a) en forbindelse med den almene formel

NH2 12 1 2 hvor R , R , L og L har de Ovenfor angivne betydninger. Forbindelsen med formeln IV1 er også indbefattet inden for rammerne af den foreliggende opfindelse. I nærværende beskrivelse er nomenklaturen og formlen for disse forbindelser som en helhed beskrevet som henholdsvis 2-iminotiazolidinderivater og som formel IV.
Omsætningen mellem en forbindelse med formel III og tiourinstof gennemføres normalt i et opløsningsmiddel. Som eksempler på sådanne opløsningsmidler kan nævnes alkoholer (fx metanol, ætanol, propanol, butanol eller ætylenglykolmonometyl-æter), ætere (fx tetrahydrofuran eller dioxan), acetone, dlme-tylsulfoxyd, sulfolan eller dimetylformamid. Idet det ikke er nødvendigt at kontrollere de relative mængder af udgangsmaterialer kritisk, er det normalt ønskeligt at anvende et lille overskud af tiourinstof i forhold til forbindelsen med formel III. Således anvendes der fortrinsvis 1-2 mol ækvivalenter tiourinstof i forhold til forbindelsen med formel III. Idet reaktionsbetingelser såsom reaktionstemperatur og reaktionstid afhænger af sådanne faktorer som udgangsmateriale, opløs- 149023 5 ningsmiddel osv. gennemføres denne reaktion normalt ved kogepunktet for det anvendte opløsningsmiddel eller ved 100-130°C i få til godt 10 timer. Den svagt opløselige iminoforbindelse med formel IV fremstilles på den ovenfor beskrevne måde. Denne iminoforbindelse med formel IV kan isoleres før det efterfølgende hydrolysetrin eller man kan direkte hydrolysere den reaktionsblanding som indeholder forbindelsen IV. I hydrolysetrinnet opvarmes iminoforbindelsen IV i et passende opløsningsmiddel (fx sulfolan) og i nærværelse af vand og mineralsyre.
Denne syre tilsættes normalt i en mængde på 0,1-10 mol ækvivalenter, fortrinsvis 0,2-3 ækvivalenter, beregnet i forhold til forbindelsen III, mens der normalt anvendes vand i et stort overskud i forhold til forbindelsen III. Opvarmningstiden ligger normalt fra få timer til godt 10 timer, b) Det omhandlede tiazolidinderivat med formel I fremstilles ifølge fremgangsmåde b) ved, at man ringslutter en forbindelse med formlen L1 __

Denne ringslutningsreaktion gennemføres normalt ved at hydrolysere en forbindelse med formel V med vand. Hydrolysen gennemføres normalt i nærværelse af en katalysator, hvor eksempler på denne katalysator indbefatter hydrogenhalogenider (fx hydrogenklorid eller hydrogenbromid), mineralsyrer såsom saltsyre eller svovlsyre. Katalysatoren kan generelt anvendes i en mængde på 20-50 mol ækvivalenter i forhold til forbindelsen med formlen V. Denne reaktion kan gennemføres i nærværelse af et organisk opløsningsmiddel såsom alkohol (fx metanol eller ætanol). Idet reaktionstemperaturen varierer med den anvendte type katalysator kan reaktionen generelt gennemføres ved en temperatur på mellem 50 og 150°C. Reaktionstiden vil sædvanligvis ligge mellem 2-30 timer.

Som base kan nævnes' natriumhydrid, kaliumkarbonat, natriumkarbonat, kaliumhydroxyd eller natriumhydroxyd. Denne reaktion gennemføres normalt i nærværelse af et opløsningsmiddel. Som et passende opløsningsmiddel kan nævnes dimetylformamid eller dimetylsulfoxyd. Reaktionstemperaturen kan ligge mellem stuetemperatur og 100°C.
Det vundne tiazolidinderivat med formlen I kan isoleres og renses ved konventionelle procedurer såsom koncentrering ved atmosfærisk tryk eller ved overtryk, opløsningsmiddelekstraktion, krystallisation, omkrystallisation, faseoverføring eller kromatografi.
Forbindelsen med formel III, som anvendes som udgangsmateriale ved den ovennævnte fremgangsmåde (a) kan fx fremstilles ved diazotering af den tilsvarende anilinforbindelse hvorefter den vundne diazoforbindelse underkastes Meerwein-arylering.
Fremgangsmåden ifølge opfindelsen belyses nærmere i det følgende ved hjælp af et referenceeksempel, der viser fremstillingen af udgangsmateriale, samt nogle udførelseseksempler.

Referenceeksempel 1 I 200 ml metanol opløses 19,0 g 4-[2-(Ν,Ν-dibutylamino)-ætyloxy]-nitrobenzen og efter tilsætning af 3 g 10%s Pd-C (fugtighed 50%) gennemføres der katalytisk reduktion ved atmosfærisk temperatur og tryk. Reaktionssystemet absorberer ca.
4,4 liter hydrogen på 75 minutter. Derpå filtreres katalysatoren fra, filtratet koncentreres under nedsat tryk og den olie-agtige remanens opløses i en blanding af 100 ml metanol og 100 ml acetone. Efter tilsætning af 21,5 ml koncentreret saltsyre afkøles opløsningen til 0°C og en opløsning af 4,9 g natriumnitrit i 10 ml vand tilsættes dråbevis ved en temperatur som ikke overskrider 5°C. Blandingen omrøres ved 5°C i 20 minutter efter hvilket tidsrums afslutning der tilsættes 33,3 g (34,9 ml) metylakrylat. Reaktionsblandingen opvarmes til 35°C og 1 g kuprooxyd tilsættes i små portioner hvorved reaktions-systemets temperatur stiger til 44°C under udvikling af nitrogengas. Blandingen omrøres i 1 time og efter at temperaturen er faldet til stuetemperatur henstår blandingen natten over. Derefter sidestilleres opløsningsmidlet under nedsat tryk og remanensen gøres kraftigt basisk med koncentreret ammoniakvand. Efter tilsætning af vand gennemføres der derpå ekstraktion med ætylacetat. Ekstrakten vaskes med vand, tørres over natriumsulfat og destilleres til fjernelse af ætylacetatet. Den olie-agtige remanens kromatograferes på en kolonne med 200 g sili-kagel og der udføres eluering med en blanding af æter og n-hexan i forholdet 1:4. På denne måde vindes 10,7 g (44,8%) metyl-2-klor-3-(4-[2-(Ν,Ν-dibutylamino)-ætyloxy]-fenyl)-pro-pionat.

Forsøgsresultater
Som forsøgsdyr anvendtes genetisk meget fede og diabetiske mus, yellow KK^ (hanner, 9 uger gamle). Efter forudgående fodring med et laboratorlefoder (CE-2, CLEA Japan) i tre dage blev de fordelt i forsøgsgrupper med 5 mus i hver gruppe på en sådan måde at den gennemsnitlige blodglukose i hver gruppe var den samme. De under afprøvning værende forbindelser blandedes omhyggeligt ved koncentrationer på 0,1% eller 0,02% i den pulverformige CE-2 diæt. Musene fodredes med forsøgsdiæten og vand ad libitum i 4 dage. Der blev udtaget blodprøver fra orbitalvenen. Blodglukose og plasmatri- 2) glycerid bestemtes ved henholdsvis glukoseoxidase-metoden 3) og Fletchers metode . Det maxiraale fald i niveauerne for blodglukose og plasmatriglycerid beregnedes som procentuel ændring i forhold til kontrolværdien.
