Forbindelserne med formlen I, som fremstilles ifølge opfindelsen, har hypotensiv, bradykardisk og diuretisk virkning.

Forbindelserne med formlen (III) og med formlen (IV) benyttes i ren tilstand eller fremstilles in situ i overensstemmelse 25 med fremgangsmåder, som er velkendte i litteraturen (Reel. Trav. Chim. Pays-Bas 98, 371-380, 1979).
Salte kan fremstilles ud fra forbindelserne med den almene formel (I) med farmaceutisk acceptable uorganiske syrer,
f.eks. saltsyre, hydrogenbromidsyre, salpetersyre, svovlsyre o U
eller phosphorsyre, eller med organiske carboxylsyrer, f.eks. eddikesyre, propionsyre, glycolsyre, malonsyre, ravsyre, male-insyre, hydroxymaleinsyre, fumarsyre, æblesyre, vinsyre, citronsyre, glueuronsyre, benzoesyre, mandelsyre, salicylsyre, __ 4-aminosalicylsyre, 2-phenoxybenzoesyre, pamosyre, nikotinsyre 3 5 eller isonikotinsyre, eller ved anvendelse af organiske sul-fonsyrer, f.eks. methansulfonsyre, ethansu1 fonsyre, 2-hydroxy-
DK 159317 B
3 ethansul fonsyre, ethan-l,2-disulfonsyre, p-toluensulfonsyre eller naphthalen-2-sulfonsyre.
Forbindelserne med den almene formel (I) og syreadditionssal-5 tene deraf er stabile ved 37°C såvel i efterlignet mavesaft som i tarmsaften.
De ifølge opfindelsen fremstillede forbindelser med formlen (I) og syreadditionssaltene deraf har bemærkelsesværdig hypo-10 tensiv, bradykardisk og diuretisk aktivitet. Doserne, der skal anvendes oralt ved behandling af mennesker, ligger i intervallet fra 0,3 til 100 mg.
De ifølge opfindelsen fremstillede forbindelser med formlen 15 (I) har visse fordele, som anføres nedenfor, sammenlignet med deres respektive forløbere (forbindelser med den almene formel (I), men hvori R = H). Især 2-[N-2,6-dich1orpheny1-N-(2-tetra-hydropyranyl)amino]-imidazolin-(2) og 2-[N-(2,6-dichlorphe-nyl)-N-(2-tetrahydrofuranyl)amino]-imidazolin-(2) viser flere 20 fordele sammenlignet med 2-(2,6-di chior-ani1 i no)-A2-imidazo-lin (clonidin) (Merck Index, 10. udg., side 340, nr. 2353).
Endog ved doser, som er større end de i de efterfølgende tabeller anførte, ændrer forbindelserne med formlen (I) ikke 25 dyrets opførsel. Endvidere mangler forbindelserne med formlen (I) såvel stimulerende som inhiberende egenskaber over for de α-adrenerge receptorer og det parasympatiske system.
Forbindelse nr. 1 viser en mere effektiv og vedvarende hypo-30 tensiv virkning end forbindelsen clonidin (tabel I), og den har en gunstig opførsel ved de forsøg, som viser eventuelle bivi rkni nger.
Tabel I viser, at clonidin, som administreres oralt til rot-35 ter, forårsager indledningsvise trykstigninger, hvilket viser perifer α-adrenerg virkning, hvilken egenskab betragtes som uønsket i den kliniske litteratur (Hunyor S.N. et al. Brit.
DK 159317 B
4
Med., 4, 23 (1975), Wing L.M.H et al. Brit. Med., 1, 136 (1977)). Derimod er denne hypertensive fase ikke til stede efter tilsvarende doser af forbindelsen nr. 1.
5 Endvidere frembringer administration af 5 μΜ/kg clonidin til vågne hunde - efter et indledningsvis arterielt trykfald, der varer 90 minutter - en bemærkelsesværdig stigning i det arterielle tryk med symptomer på rastløshed og rystelser eller skælven, hvilke symptomer kan sammenlignes med den som "reak-10 tion" observerede hypertensive krise hos mennesker (Lesley
Matier W. and Comer W.T., Annual Reports in Medicinal Chemistry, 13 (1978) kapitel 8 - Antihypertensive agents, side 71 og 72). Den samme dosis af forbindelsen nr. 1 viser derimod kun en vedvarende hyptensiv virkning i hunde.
15
Endelig er forbindelse nr. 1 henholdsvis 40 og 800 gange mindre aktiv end clonidin i henseende til formindskelse af den spontane mobilitet af henholdsvis rotter og mus (tabel IV), og den viser derfor en i virkeligheden usignifikant sedativ 20 aktivitet. Denne aktivitet er uønsket hos mennesker (Lesley
Matier W. and Comer W.T. 1978).
De ifølge opfindelsen fremstillede forbindelser med formlen (I) kan administreres oralt, ved indsprøjtning eller rektalt 25 under anvendelse af passende farmaceutiske præparater i fast, flydende eller suspenderet form (tabletter, kapsler, piller, siruper, suppositorier o.s.v.).
De efterfølgende ikke-begrænsende tabeller opsummerer de far-30 makologiske egenskaber for forbindelse nr. 1, d.v.s. 2-[N-2,6-dichlorphenyl)-N-(2-tetrahydropyrany1)amino]-imidazol in-(2), og for forbindelse nr. 2, d.v.s. 2-[N-(2,6-dichlorphenyl)-N-(tetrahydrofurany1)amino]imidazolin-{2).

De hypotensive og bradykardiske virkninger er blevet undersøgt på vågne rotter og hunde ved hjælp af kronisk indklem-ning (incannulation) af henholdsvis halspulsåren og saphena-arterien samt kontinuerlig registrering ved hjælp af trans-5 ducere.
Den diuretiske virkning er blevet undersøgt på vågne rotter under væskebelastning (hydric load) (fysiologisk opløsning, 25 ml/kg, oralt).

De følgende eksempler illustrerer fremgangsmåden ifølge opfindelsen .
Smeltepunkterne er ikke korrigerede. Identiteten og renheden 5 af stofferne blev kontrolleret ved hjælp af grundstofanalyse for C, Η, N og Cl samt i nfrarødt, kernemagnetisk og ultraviolet spektrum.
Eksempel 1 10 2-[N-(2,6-dichlorphenyl)-N-(2-tetrahydropyranyl)am i no]imidazo-1 i n - (2).
Til en opløsning af 2,46 g (10,2 millimol) 2-(2,6-dichlorphe-15 nylimino)-imidazol in i 60 ml vandfrit methylenchlorid sættes langsomt under omrøring ved stuetemperatur 0,28 g (12,24 millimol) NaH. Efter tilsætningen omrøres opløsningen atter i 60 minutter, køles derpå til -40°C, og en opløsning af 1,6 g (13,26 millimol) 2-chlor-tetrahydropyran i 2 ml vandfrit 20 methylenchlorid tilsættes dråbevis. Efter tilsætningen fjernes kølebadet, og stuetemperatur opnås. Efter filtrering vaskes opløsningen med en fortyndet opløsning af NH4OH, hvorpå den tørres over Na2S04 og inddampes til tørhed ved reduceret tryk. Smeltepunkt = 122-123°C (fra hexan).
