så vel som tautomerene, enantiomerene, diastereomerene, blandingene derav og saltene derav.
I henhold til oppfinnelsen blir forbindelsene med den generelle formel I oppnådd ved metoder som er kjent perse, for eksempel ved de følgende metoder:
a) omsetning av en forbindelse med den generelle formel
hvor
R<1>til R<3>er som definert ovenfor og
Z<1>betyr en utgående gruppe så som et halogenatom så som et klor- eller bromatom, en substituert hydroksy-, merkapto-, sulfinyl-, sulfonyl- eller sulfonyloksygruppe, en metansulfonyl- eller metansulfonyloksygruppe,
med 3-aminopiperidin, enantiomerene derav eller saltene derav.
Det er hensiktsmessig å utføre reaksjonen i et løsningsmiddel så som isopropanol, butanol, tetrahydrofuran, dioksan, dimetylformamid, dimetylsulfoksyd, etylenglykol-monometyleter, etylenglykol-dietyleter eller sulfolan, eventuelt i nærvær av en uorganisk eller tertiær organisk base, f.eks. natriumkarbonat, kaliumkarbonat eller kaliumhydroksyd, en tertiær organisk base, f.eks. trietylamin, eller i nærvær av N-etyl-diisopropylamin (Hunig-base), hvor disse organiske basene samtidig kan tjene som løsningsmiddel, og eventuelt i nærvær av en reaksjonsakselerator så som et alkalimetallhalogenid eller en palladium-basert katalysator, ved temperaturer mellom -20 og 180°C, men fortrinnsvis ved temperaturer mellom -10 og 120°C. Reaksjonen kan imidlertid også utføres uten løsningsmiddel eller med overskudd av 3-aminopiperidin.
b) avbeskyttelse av en forbindelse med den generelle formel
hvorR<1>,R2 og R<3>er som definert ovenfor.
Tert-butyloksykarbonylgruppen blir fortrinnsvis spaltet ved behandling med en syre så som trifluoreddiksyre eller saltsyre, eller ved behandling med bromtrimetylsilan eller jodtrimetylsilan, eventuelt ved anvendelse av et løsningsmiddel så som metylenklorid, etylacetat, dioksan, metanol, isopropanol eller dietyleter, ved temperaturer mellom 0 og 80°C. c) For å fremstille en forbindelse med den generelle formel I, hvor R<1>i henhold til definisjonen ovenfor, inneholder en karboksygruppe:
avbeskyttelse av en forbindelse med den generelle formel
hvor R<2>og R3 er som definert ovenfor og R1 inneholder en karboksygruppe som er beskyttet med en Ci-4-alkylgruppe.
Beskyttelsesgruppen blir spaltet ved hydrolyse, for eksempel ved anvendelse av en syre så som saltsyre eller svovelsyre, eller et alkalimetallhydroksyd så som litiumhydroksyd, natriumhydroksyd eller kaliumhydroksyd, i et løsningsmiddel så som metanol, etanol, isopropanol, tetrahydrofuran eller dioksan i nærvær av vann.
I reaksjonene som er beskrevet ovenfor, kan eventuelle reaktive grupper som er til stede, så som karboksy-, amino-, alkylamino- eller iminogrupper, beskyttes under reaksjonen med konvensjonelle beskyttelsesgrupper som blir spaltet igjen etter reaksjonen.
En beskyttelsesgruppe for en karboksygruppe kan for eksempel være en trimetylsilyl-, metyl-, etyl-, tert-butyl-, benzyl- eller tetrahydropyranylgruppe og
beskyttelsesgrupper for en amino-, alkylamino- eller iminogruppe kan være en formyl-, acetyl-, trifluoracetyl-, etoksykarbonyl-, tert-butoksykarbonyl-, benzyloksykarbonyl-, benzyl-, metoksybenzyl- eller 2,4-dimetoksybenzylgruppe, og for aminogruppen dessuten en ftalylgruppe.
Eventuelle beskyttelsesgruppe som anvendes blir deretter eventuelt spaltet for eksempel ved hydrolyse i et vandig løsningsmiddel, f.eks. i vann, isopropanol/vann, eddiksyre/vann, tetrahydrofuran/vann eller dioksan/vann, i nærvær av en syre så som trifluoreddiksyre, saltsyre eller svovelsyre, eller i nærvær av en alkalimetall-base så som natriumhydroksyd eller kaliumhydroksyd, eller aprotisk, f.eks. i nærvær av jodtrimetylsilan, ved temperaturer mellom 0 og 120°C, fortrinnsvis ved temperaturer mellom 10 og 100°C.
En benzyl-, metoksybenzyl- eller benzyloksykarbonylgruppe blir imidlertid spaltet for eksempel hydrogenolytisk, f.eks. med hydrogen i nærvær av en katalysator så som palladium/trekull, i et egnet løsningsmiddel så som metanol, etanol, etylacetat eller iseddik, eventuelt ved tilsetning av en syre så som saltsyre, ved temperaturer mellom 0 og 100°C, men fortrinnsvis ved temperaturer mellom 20 og 60°C, og ved et hydrogentrykk på 1 til 7 bar, men fortrinnsvis 3 til 5 bar. En 2,4-dimetoksybenzylgruppe blir imidlertid fortrinnsvis spaltet i trifluoreddiksyre i nærvær av anisol.
En tert-butyl- eller tert-butyloksy karbonyl gruppe blir fortrinnsvis spaltet ved behandling med en syre så som trifluoreddiksyre eller saltsyre, eller ved behandling med jodtrimetylsilan, eventuelt ved anvendelse av et løsningsmiddel så som metylenklorid, dioksan, metanol eller dietyleter.
En trifluoracetylgruppe blir fortrinnsvis spaltet ved behandling med en syre så som saltsyre, eventuelt i nærvær av et løsningsmiddel så som eddiksyre, ved temperaturer mellom 50 og 120°C, eller ved behandling med natriumhydroksyd-løsning, eventuelt i nærvær av et løsningsmiddel så som tetrahydrofuran, ved temperaturer mellom 0 og 50°C.
En ftalylgruppe blir fortrinnsvis spaltet i nærvær av hydrazin eller et primært amin så som metylamin, etylamin eller n-butylamin, i et løsningsmiddel så som metanol, etanol, isopropanol, toluen/vann eller dioksan, ved temperaturer mellom 20 og 50°C.
Videre kan de oppnådde forbindelser med den generelle formel I spaltes til deres enantiomerer og/eller diastereomerer, som nevnt ovenfor. Følgelig kan for eksempel cis/trans-blandinger spaltes til deres cis- og trans-isomerer, og forbindelser med minst ett optisk aktivt karbonatom kan separeres til deres enantiomerer.
Følgelig kan for eksempel cis/trans-blandinger spaltes ved kromatografi til cis- og trans-isomerer derav, de oppnådde forbindelser med den generelle formel I som forekommer som racemater, kan separeres ved metoder som er kjent per se (jf. Allinger N. L. og Eliel E. L. i "Topics in Stereochemistry", vol. 6, Wiley Interscience, 1971) til deres optiske antipoder, og forbindelser med den generelle formel I som har minst 2 asymmetriske karbonatomer, kan spaltes til deres diastereomerer på grunnlag av deres fysikalsk-kjetniske forskjeller, ved anvendelse av metoder som er kjent per se, f.eks. ved kromatografi og/eller fraksjonert utkrystallisasjon, og dersom disse forbindelsene blir oppnådd i racemisk form, kan de deretter spaltes til enantiomerene som nevnt ovenfor.
Enantiomerene blir fortrinnsvis separert ved kolonneseparering på chirale faser eller ved omkrystallisering fra et optisk aktivt løsningsmiddel eller ved omsetning med en optisk aktiv substans som danner salter eller derivater, så som f.eks. estere eller amider, med den racemiske forbindelse, spesielt syrer og de aktiverte derivater eller alkoholer derav, og ved å separare den således oppnådde diastereomere blanding av salter eller derivater, f.eks. på grunnlag av deres forskjellige oppløselighet, mens de frie antipoder kan frigjøres fra de rene diastereomere salter eller derivater ved hjelp av egnede midler. Vanlig brukte optisk aktive syrer er f.eks. D- og L-formene av vinsyre eller dibenzoylvinsyre, di-o-tolylvinsyre, eplesyre, mandelsyre, kamfersulfonsyre, glutaminsyre, asparaginsyre eller kininsyre. En optisk aktiv alkohol kan for eksempel være (+)- eller (-)-mentol, og en optisk aktiv acylgruppe i amider kan for eksempel være en (+)-eller (-)-mentyloksykarbonyl.
Videre kan forbindelsene med formel I omdannes til saltene derav, for farmasøytisk anvendelse spesielt til de fysiologisk akseptable salter med uorganiske eller organiske syrer. Syrer som kan anvendes for dette formål omfatter for eksempel saltsyre, bromhydrogen-syre, svovelsyre, fosforsyre, fumarsyre, ravsyre, melkesyre, sitronsyre, vinsyre eller maleinsyre.
Dersom de nye forbindelsene med formel I som er oppnådd slik, videre inneholder en karboksygruppe, kan de deretter, om ønskelig, omdannes til saltene derav med uorganiske eller organiske baser, for farmasøytisk anvendelse spesielt til de fysiologisk akseptable salter derav. Egnede baser for dette formål omfatter for eksempel natriumhydroksyd, kaliumhydroksyd, arginin, cykloheksylamin, etanolamin, dietanolamin og trietanolamin.
Forbindelsene med de generelle formler II til IV, som benyttes som utgangsmaterialer, er enten kjente fra litteraturen eller kan oppnås ved metoder som er kjente fra litteraturen (jf. Eksempel I til LXXI).
Som allerede nevnt ovenfor, har forbindelsene med den generelle formel I ifølge oppfinnelsen og de fysiologisk akseptable salter derav, verdifulle farmakologiske egenskaper, spesielt en inhiberende effekt på enzymet DPP-IV.
De biologiske egenskaper til de nye forbindelsene ble undersøkt som følger:
Den evne substansene og deres korresponderende salter har til å inhibere DPP-IV-aktivitet, kan demonstreres i et test-oppsett hvor et ekstrakt av den humane kolonkarsinom-cellelinje Caco-2 blir anvendt som DPP-IV-kilden. Differensiering av cellene for å fremkalle DPP- IV-ekspresjon, ble utført som beskrevet av Reiher et al. i artikkelen "Increased expression of intestinal cell line Caco-2", som ble trykket i Proe. Nati. Acad. Sei., vol. 90, s. 5757-5761 (1993). Celleekstraktet ble oppnådd fra celler som var solubilisert i en buffer (lOmM Tris HC1, 0,15 M NaCl, 0,04 t.i.u. Kirsti aprotinin, 0,5% Nonidet-P40, pH 8,0) ved å sentrifugere ved 35,000 g i 30 minutter ved 4°C (for å fjerne celledebris).
DPP-IV-assayet ble utført som følger:
50 fil substratløsning (AFC; AFC er amido-4-trifluormetylkumarin), totalkonsentrasjon 100 uM, ble plassert i sorte mikrotiter-plater. 20 ul assaybuffer (totalkonsentrasjoner 50 mM Tris HC1 pH 7,8, 50 mM NaCl, 1 % DMSO) ble pipettert i. Reaksjonen ble startet ved tilsetning av 30 ul solubilisert Caco-2-protein (endelig konsentrasjon 0,14 ug protein pr. brønn). Testsubstansene som skulle undersøkes, var typisk fortynnet på forhånd i 20 ul, og volumet av assaybufferen ble tilsvarende redusert. Reaksjonen ble utført ved omgivelsestemperatur og ved inkubering i 60 minutter. Deretter ble fluorescensen målt i en Victor 1420 Multilabel Counter, hvor eksitasjons-bølgelengden var 405 nm og emisjons-bølgelengden var 535 nm. Blanke avlesninger (tilsvarte 0 % aktivitet) ble oppnådd i blandinger uten noe Caco-2-protein (volum erstattet av assaybuffer), kontrollverdier (tilsvarte 100 % aktivitet) ble oppnådd i blandinger uten tilsatt substans. Styrken av de aktuelle testsubstanser, uttrykt som ICso-verdier, ble beregnet fra dose/aktivitet-kurver som i hvert tilfelle bestod av 11 målepunkter. De følgende resultater ble oppnådd:
Forbindelsene som er fremstilt ifølge oppfinnelsen blir godt tolerert, som for eksempel når 10 mg/kg av forbindelsen i eksempel 2(80) ble administrert til rotter oralt, kunne ingen endringer i dyrenes adferd påvises.
I lys av av deres evne til å inhibere DPP-IV-aktivitet, er forbindelsene med den generelle formel I ifølge oppfinnelsen og de korresponderende farmasøytisk akseptable salter derav, egnet for behandling av alle de tilstander eller sykdommer som kan påvirkes ved inhibering av DPP-IV-aktivitet. Det er derfor forventet at forbindelsene ifølge oppfinnelsen vil være egnet for forebygging eller behandling av sykdommer eller tilstander så som type 1 og type 2 diabetes mellitus, diabetiske komplikasjoner (som f.eks. retinopati, nefropati eller nevropatier), metabolsk acidose eller ketose, reaktiv hypoglykemi, insulinresistens, metabolsk syndrom, dyslipidemier av forskjellig opprinnelse, artritt, aterosklerose og beslektede sykdommer, fedme, allograft-transplantasjon og kalsitonin-indusert osteoporose. Dessuten kan disse substansene forebygge B-celle-degenerasjon som f.eks. apoptose eller nekrose av B-celler i pankreas. Substansene er også egnet for å forbedre eller gjenopprette funksjonen til pankreasceller og også øke antallet av og størrelsen til B-celler i pankreas. I tillegg, og på grunnlag av rollen til glukagon-lignende peptider, som f.eks. GLP-1 og GLP-2 og deres kobling til DPP-IV-inhibering, er det sannsynlig at forbindelsene ifølge oppfinnelsen er egnet for å oppnå bl.a. en sedativ eller angstlindrende effekt og at de også på fordelaktig måte påvirker katabolske tilstander etter operasjoner eller hormonelle stressresponser eller reduserer dødelighet eller sykdom etter myokard-infarkt. De er også egnet for behandling av alle tilstander som er forbundet med de ovennevnte effekter og som blir mediert av GLP-1 eller GLP-2. Forbindelsene ifølge oppfinnelsen kan også anvendes som diuretika eller antihypertensiva og er egnet for forebygging og behandling av akutt nyresvikt. Videre kan forbindelsene ifølge oppfinnelsen anvendes for å behandle inflammatoriske sykdommer i luftveiene. De er også egnet for forebygging og behandling av kroniske inflammatorisk tarmsykdommer som f.eks. irritabel tarm-syndrom (IBS), Crohns sykdom eller ulcerøs kolitt og også pankreatitt. Det er også sannsynlig at de kan anvendes for alle typer skade på eller svekkelse av mave/tarm-kanalen, som for eksempel kolitt og enteritt. Det er også forventet at DPP-IV-inhibitorer og følgelig også forbindelsene ifølge oppfinnelsen, kan anvendes for å behandle sterilitet eller for å forbedre fruktbarhet hos mennesker eller pattedyr, spesielt når steriliteten er relatert til insulinresistens eller polycystisk eggstokksyndrom. På den annen side er disse substansene egnet for å påvirke sædcelle-motilitet og kan følgelig anvendes som prevensjonsmidler for menn. Substansene er også egnet for behandling av veksthormonmangel som er relatert til redusert høydevekst, og kan med fordel også anvendes for alle indikasjoner hvor veksthormon kan anvendes. Forbindelsene ifølge oppfinnelsen er, på grunnlag av deres inhiberende effekt på DPP-IV, også egnet for behandling av forskjellige autoimmune sykdommer som f.eks. revmatoid artritt, multippel sklerose, tyreoiditt og Basedows sykdom osv. De kan også anvendes for å behandle virussykdommer og også for å stimulere blodproduksjon, for eksempel ved HIV-infeksjoner, ved godartet prostatahyperplasi, gingivitt, så vel som for behandling av nevronale defekter og nevrodegenerative sykdommer som for eksempel Alzheimers sykdom. De beskrevne forbindelser kan også anvendes for behandling av tumorer, spesielt for modifikasjon av tumorinvasjon og også metastasering; eksempler her er anvendelse av dem ved behandling av T-celle-lymfomer, akutt lymfoblastisk leukemi, celle-baserte pankreatiske karsinomer, basalcelle-karsinomer eller brystkreft. Andre indikasjoner er slag, iskemi av forskjellig opprinnelse, Parkinsons sykdom og migrene. Dessuten omfatter ytterligere indikasjoner follikulære og epidermale hyperkeratoser, øket keratinocytt-proliferasjon, psoriasis, encefalomyelitt, glomerulonefritt, lipodystrofier, så vel som psykosomatiske, depressive og nevropsykiatriske sykdommer av alle typer.
Forbindelsene ifølge oppfinnelsen kan også anvendes sammen med andre aktive substanser. Terapeutiske midler som er egnet for slike kombinasjoner, omfatter for eksempel antidiabetika så som metformin, sulfonylurea-forbindelser (f.eks. glibenclamid, tolbutamid, glimepirid), nateglinid, repaglinid, tiazolidindion (f.eks. rosiglitazon, pioglitazon), PPAR-gamma-agonister (f.eks. GI 262570) og -antagonister, PPAR-gamma/alfa-modulatorer (f.eks. KRP 297), alfa-glukosidase-inhibitorer (f.eks. akarbose, voglibose), andre DPPIV-inhibitorer, alfa2-antagonister, insulin og insulinanaloger, GLP-1- og GLP-1-analoger (f.eks. exendin-4) eller amylin.

0,5 ml av en 1 M natriurnmetoksyd-løsning i metanol blir satt dråpevis til en løsning av 428 mg l-cyanometyl-3-metyl-7-(2-butyn-l-yl)-8-[3-(tert-butyloksykarbonylamino)-piperidin-1-yl]-xantin i 3 ml metanol ved omgivelsestemperatur. Etter ca. 20 minutter blir den dannede tykke suspensjon oppvarmet forsiktig i et vannbad og fortynnet med 2 ml metanol. Straks reaksjonen for dannelse av iminoesteren ifølge tynnskiktskromatografi er fullstendig, blir reaksjonsblandingen nøytralisert med 0,5 ml 1 M iseddik-løsning i metanol og kombinert med en løsning av 130 mg antranilsyre i 2 ml metanol. Forsiktig oppvarming gir en klar løsning som blir omrørt i 2,5 timer ved omgivelsestemperatur. Deretter blir reaksjonsblandingen forsiktig tilbakeløpskokt i ca. 3,5 timer. Etter henstand natten over ved omgivelsestemperatur, blir metanolen avdestillert og residuet blir omrørt med kaldt vann, sugefiltrert og tørket. Råproduktet blir oppslemmet i 5 ml metanol, forsiktig oppvarmet og blir etter avkjøling sugefiltrert, vasket med metanol og tørket i eksikator.
