Description
DK 154297 B
Opfindelsen angår en analogifremgangsmåde til fremstilling af hidtil ukendte optisk aktive eller racemi ske pyrido[2,l-b]-quinazoli nonder ivater af den i kravet angivne art med den almene formel I eller salte deraf med fysiologisk acceptable sy-5 rer eller bærer.
Fra US patentskrifterne nr. 4.033.961 og 4.104.389, DE patentansøgning nr. 2.557.427 samt DK patentansøgning nr. 1327/78 kendes pyrido[2,l-b]-quinazoli nonder i vater, der er nært be-10 slægtet med de ved fremgangsmåden ifølge opfindelsen fremstillede forbindelser. Ved en sammenligning under anvendelse af carragen in-poteødem-prøven fremgår det, at de ved fremgangsmåden ifølge opfindelsen fremstillede forbindelser har en væsentligt bedre hæmmende virkning på carregen i nfremka1dt pote-15 ødem sammenlignet med repræsentanter for de kendte forbindelser .
Salte af pyrido[2,l-c]-quinazolinonderivaterne med den almene formel I med fysiologisk acceptable baser er f.eks. alkali-20 metalsalte eller jordalkalimetalsalte som natriumsaltene eller calciumsaltene, eller ammoniumsalte, kobber (11)-sal te, methyl-glucaminsalte, piperazinsalte eller saltene af disse forbindelser med aminosyrer.
25 Som pyrido[2,l-b]-quinazoliniumsalte af forbindelser med den almene formel I kommer f.eks. hydrochloriderne, hydrobromider-ne, sulfaterne, phosphaterne, oxalaterne, maleaterne, tatra-terne eller citraterne i betragtning.
30 Pyrido[2,l-b]-quinazoli nonderivaterne med den almene formel I er farmakologisk virksomme stoffer. De farmakologisk virksomme forbindelser udmærker sig specielt ved en antiflogistisk, an-tipyretisk, analgetisk og antiallergisk virkning. Desuden bevirker disse forbindelser in vitro en udpræget phosphodieste-35 rasehæmning. De virksomme pyrido-[2,l-b]-quinazolinonderivater tåles relativt godt i maven, deres toksicitet er forholdsvis ringe.

De farmakologisk virksomme forbindelser egner sig i kombination med de i den galeniske farmaci sædvanlige bærestoffer til behandlingen f.eks. af akutte og kroniske betændelsesprocesser, polyarthritis, neurodermitis, astma bronchciale og høfe-5 ber.
Fremstillingen af lægemiddelspecialiteterne sker på sædvanlig måde ved, at man med egnede tilsætninger, bærestoffer og smagskorrigerende stoffer overfører de virksomme stoffer i det 10 ønskede applikationsformer som tabletter, drageer, kapsler, opløsninger og indhal tionsmidler.
Til den orale anvendelse egner sig specielt tabletter, drageer og kapsler, som f.eks. indeholder 5-500 mg virksomt stof og 50 15 mg - 2 g farmakologisk uvirksom bærer som f.eks. lactose, amy-lose, talkum, gelatine og magnesiumstearat samt de sædvanlige tilsætninger.
Fremgangsmåden ifølge opfindelsen er ejendommelig ved det i 20 kravets kendetegnende del anførte.
Fremgangsmåden ifølge opfindelsen til fremstillingen af pyri-do[2,l-b]-quinazolinonderivaterne ifølge fremgangsmåde a) gennemføres under betingelser som kendes af fagfolk (Ullmann-re-25 aktion). Som udgangsforbindelser til denne fremgangsmåde anvendes fortrinsvis sådanne pyridinderivater med den almene formel II, der som subst i tuenter Y har en aminogruppe, et chloratom, et bromatom, en alkoxygruppe med 1-4 carbonatomer i alkylresten, en trimethylsilyloxygruppe, en methansulfonyloxy-30 gruppe eller en p-toluensulfonyloxygruppe. De som udgangsforbindelser anvendte phenylderivater med den almene formel III har fortrinsvis som substituent V et hydrogenatom eller en al-kylgruppe med 1-4 carbonatomer, og som substituent Z en aminogruppe, et chloratom eller et bromatom. Med alkoxycarbony1 -35 grupper X1 i forbindelsen III skal fortrinsvis forstås grupper med 1-4 carbonatomer i alkylresten.
Reaktionen gennemføres fortrinsvis ved at man opvarmer reaktionskomponenterne om ønsket i et højt kogende opløsningsmid- 3
DK 154297 B
del (f.eks. ethylenglycol, ethylenglycolmonomethylether, ethy-lenglycolmonobutylether eller ethylenglycoldiethylether) i nærværelse af baser med kobber- eller zinkkat’alysatorer til 100-250°C. Egnede baser er f.eks. alkalicarbonater (natrium-5 carbonat eller kaliumcarbonat) eller højt kogende tertiære a-miner (N-ethylmorpholin, N-ethylpiperidin etc.). Som egnede kobber- eller zinkkatalysatorer skal f.eks. nævnes zink(II)-chlorid, kobberpulver, kobber (I)-oxid, kobber(II)-oxid, kob-ber(II)-chlorid, kobber (11)-sul fat eller specielt kobber(II)-10 bromid og kobber(I)-bromid.
Fremgangsmåden ifølge opfindelsen ifølge metode b) sker ligeledes under betingelser som kendes af fagfolk. Således kan ni-trilerne f.eks. hydrolyseres med stærke mineralsyrer (som 15 saltsyre eller svovlsyre) eller med stærke baser (som vandig natriumhydroxid eller kaliumhydroxid) partielt til de tilsvarende amider eller under forstærkede betingelser til de tilsvarende carboxylsyrer.
20 Til denne reaktion kan den vandholdige mineralsyre eller base selv anvendes som opløsningsmiddel. Det er imidlertid også på den anden side muligt at gennemføre reaktionen i nærværelse af polære opløsningsmidler som f.eks. lavere alkoholer (methanol, ethanol, isopropanol etc.), carboxylsyrer (eddikesyre, propi-25 onsyre etc.), polære ethere (glycolmonomethylether, dioxan, tetrahydrofuran etc.) eller dipolære aprotiske opløsningsmidler (dimethylsulfoxyd etc.).
Hydrolysen gennemføres sædvanligvis ved en reaktionstemperatur 30 på 20eC - 160°C.
De til denne reaktion anvendte udgangsforbindelser med den almene formel la kan fremstilles ifølge fremgangsmåden ifølge metode a) eller e).
Fremgangsmåden ifølge opfindelsen ifølge metode c) gennemføres ligeledes under betingelser som kendes af fagfolk. Denne reaktion gennemføres ved thermisk opvarmning af malonsyrederiva- 35 4
DK 154297 B
terne med den almene formel IV til 50°C - 150°C, hvorved man kan gennemføre decarboxyleringen uden nærværelse af et opløsningsmiddel eller i nærværelse af et højt kogende opløsningsmiddel (som xylen, chlorbenzen eller dekalin).
5
De til denne fremgangsmåde anvendte udgangsforbindelser med den almene formel IV kan f.eks. fremstilles således: Pyrido [2,l-b]-quinazoli nonder i vater med den almene formel I, hvori Ri betyder hydrogen, og carboxygruppen er erstattet af en cy-10 anogruppe eller alkoxycarbonylgruppe, omsættes i diethylcarbo-nat med natriumhydrid. Man afdest i 11 erer overskud af opløsningsmiddel og kan så eventuelt methylere det opnåede råprodukt i dimethylformamid med methyljodid og natriumhydrid.
15 Fremgangsmåden ifølge metode d) sker ligeledes under betingelser, der kendes af fagfolk. Således kan f.eks. forbindelserne med den almene formel V i et inaktivt opløsningsmiddel (dio-xan, tetrahydrofuran, glycoldimethylether etc.) omsættes med 1ithiumdiisopropylamid og carbondioxid. På den anden side er 20 det f.eks. også muligt at omsætte forbindelserne med den almene formel I i et inaktivt opløsningsmiddel (dioxan, tetrahy-drofuran, glycoldimethylether etc.) med kaliumhydrid og chlor-carbonsyreethylester.
25 De til disse fremgangsmåder nødvendige udgangsforbindelser med den almene formel V kan f.eks. fremstilles ifølge metode a).
De øvrige foranstaltninger ifølge metoderne a), b), c) eller 30 d) kan f.eks. gennemføres under betingelserne, som er beskrevet i tysk offentliggørelsesskrift nr. 24 31 292.
Fremgangsmåden ifølge metode e) kan gennemføres under betingelserne, som sædvanligvis anvendes til ombytning af halogen-35 atomer med en cyanogruppe.
Denne reakt i on gennemføres fortrinsvis i et protisk opløsningsmiddel (som methanol, ethanol, isopropanol) eller et di- 5
DK 154297 B
polært, aprotisk opløsningsmiddel (som dimethyl foramid, N-me-thylacetamid, N-methylpyrrolidon, acetonitril, dimethylsulf-oxid eller hexamethylphosphorsyretriamid). Sojn alkalimetal-cyanider anvendes til denne reaktion fortrinsvis natriumcyanid 5 eller kaliumcyanid.
Ved denne omsætning kan man ofte forhøje produktudbyttet, når man gennemfører omsætningen i nærværelse af en kroneether (f.eks. dibenzo-18-krone-6).
10
Fremstillingen af forbindelserne med den almene formel VII, der kræves som udgangsforbindelser for fremgangsmåden ifølge metode e), er beskrevet i de efterfølgende udførelseseksemp ler.

Biologisk dokumentation Carragenin-poteødem-prøve 5 (jvf. Proc. Soc. Exptl. Biol. Med. 111, 1962, 544).
I rottepote fremkaldtes en akut exsudativ betændelse ved indsprøjtning af en carrageninopløsning. Denne betændelse kan hæmmes ved hjælp af antiflogistiske forbindelser. Ødemet måles 10 volumetrisk.
Der blev anvendt SPF-Wistar-hanrotter med en vægt på mellem 120 og 140 g. 16 timer før oral indgift af den under afprøvning værende forbindelse blev foder taget fra dyrene mens de 15 modtog vand ad libitum. Som betændelsesfremkaldende middel anvendes carragenin. 10 mg/ml carragenin optages i 0,9% kogsaltopløsning, og der indsprøjtes 0,1 ml i rottepoten.
En enkelt dosis af det under afprøvning værende stof indgives 20 til hvert forsøgsdyr én gang 1 time før ødemfremkaldelse i 0,5 ml af bærestoffet pr. 100 g legemsvægt. Som bærestof anvendes fysiologisk kogsaltopløsning; ved ikke vand-opløselige stoffer fremstilles en mikrosuspension i fysiologisk natriumchlorid-opløsning med Myrj 53 (85 mg/100 ml).
