Description
Oppfinnelsen vedrører fremstilling av- de nye, terapeutisk aktive pyridinderivatene med formel ^1)
hvor
Q står for en nitro- eller cyangruppe, og
X<x> og X^, uavhengig av hverandre, representerer hydrogen eller halogen eller en trifluormethyl-, en lavere alkyl-eller alkoxy- eller nitrogruppe bundet til et hvilket som helst av carbonatomene i fenylringen.
Forbindelsene med formel (I), dvs. forbindelsene fremstilt i henhold til oppfinnelsen, innehar viktige biologiske virkninger. De viktigste av disse er inhibering av magesyresekresjon og vevsbeskyttende effekt. En rekke representanter av disse nye forbindelsene utøver også smerte-stillende og mildt antiinflammatoriske effekter.
Oppfinnelsen vedrører således en analogifremgangsmåte for fremstilling av de ovenfor nevnte forbindelser med formel (I). Bruken omfatter administrering av en terapeutisk effek-tiv mengde av en forbindelse med formel (I) til en pasient for inhibering av magesyresekresjon, beskyttelse av vev, lindring av smerte eller behandling av en mild inflammasjon.
Som brukt heri, hentyder "lavere" til en alkylgruppe eller alkylresten i en alkoxygruppe eller en åpenkjedet forbindelse inneholdende en kort carbonkjede bestående av inntil 8 carbonatomer.
Den biologiske aktiviteten til noen få kjente forbindelser som strukturelt ligner på forbindelsene fremstilt ifølge foreliggende oppfinnelse, er kjent. For eksempel har alkyléringen av ringnitrogenet til 2-(nitroamino)pyridin med a-halogenketoner, a-halogenestere og fenylethylhalogenider blitt beskrevet i: J. Med. Chem. 14, s. 988 (1971). Den antiinflammatoriske effekt til de oppnådde forbindelser har også blitt publisert deri.
I europeisk patentskrift nr. 9.362 (1980) har forbindelser av guanidintype blitt publisert, hvorav en under-gruppe består av (l-methyl-2-pyridyliden)guanidinderivater. Forbindelsene beskrevet i dette patentskriftet, innehar hypoglycemiske, sekresjonsinhiberende og kardiovaskulære aktiviteter.
Blant insekticidforbindelsene beskrevet i de publiserte japanske patentsøknadene nr. 63.307.857 (1988) og 63.287.764 (1988) såvel som i den publiserte europeiske patentsøknad nr. 0.259.738 (1988), har 2-(cyanimino)- og 2-(nitroimino)pyridiner substituert på ringnitrogenet av en cyanalkyl- eller 3-cyanbenzylgruppe eller av en heterocyk-lisk gruppe gjennom methylengruppen, også blitt beskrevet.
Den magesyresekresjonsinhiberende effekt til forbindelsene fremstilt i henhold til foreliggende oppfinnelse, ble studert ved bruk av Shays metode (Gastroenterology 56_, side 5 til 13 (1945)). Ifølge denne metode ble H-Wistar hunnrotter med vekt 120 til 150 g sultet i sprinkelbur i 24 timer. Dyrene mottok vann ad libitum. Deretter ble mageporten avstengt under en lett etherbedøvelse. Testforbindelsene ble administrert gjennom det kirurgiske inngrepet. Etter 4 timer ble dyrene drept med ethernarkose. Etter fjerning av magen ble volumet og pH-verdien til magesyreinnholdet målt. I en
rekke tilfeller ble saltsyreinnholdet bestemt ved titrering.
EDcjQ-verdiene (gitt som mg/kg) bestemt i testen ovenfor, er som følger:
Det bemerkes at en sammenligning av den orale ED5Q-verdi til cimetidin (kjemisk l-cyan-2-methyl-3-[2-[[(5-methylimidazol-4-yl)methyl]thio]ethyl]-guanidin) er 50 mg/kg i testen ovenfor.
En 50 mg/kg oral dose av l-benzyl-2-(cyanimino)pyridin inhiberer utviklingen av magesyresår indusert i rotter ved 40 mg/kg subkutan (s.c.) dose av 100% indomethacin (kjemisk betegnelse [1-(4-klorbenzoyl)-2-methyl-5-methoxy-indol-3-yl]-eddiksyre).
Intet toksisk symptom ble- indusert i rotter ved en enkel oral dose på 120 mg/kg av forbindelsen.
I henhold til foreliggende oppfinnelse er det fremskaffet en analogifremgangsmåte for fremstilling av pyridinderivatene med den generelle formel (I), omfattende
a) å omsette et 2-(substituert amino)pyridinderivat med formel (III)
hvori Q er som definert ovenfor, med et benzylhalogenid med formel (IV) hvori X-<*-> og X^ er som definert ovenfor og W betyr klor eller brom, i nærvær av en organisk eller uorganisk base, deretter å fraskille pyridinderivatet med formel (I) fremskaffet fra det isomere pyridinderivat med formel (V) fremstilt som et biprodukt, ;1 9 ;hvori Q, X<x> og X^ er som definert ovenfor, ;eller ;b) å omsette cyanbromid og et 2-iminopyridinderivat med den generelle formel (II) ;hvori X<x> og X^ er som definert ovenfor, eveirEuelt fremstilt in situ ved den alkaliske behandling av et pyridinsalt med den generelle formel (VI) ;hvori X<x> og X^ er som definert ovenfor og Y betyr halogenid-ion, hvorved det fås pyridinderivater med formel (I) hvori X<x >og X<*> er som definert ovenfor og Q representerer en cyangruppe.
Reaksjonen i henhold til fremgangsmåte a) utføres fortrinnsvis i et protisk eller dipolart, aprotisk løsnings-middel. Foretrukne løsningsmidler innbefatter lavere alkan-oler som ethanol, lavere ketoner som aceton eller lavere alkannitriler som acetonitril.
I fremgangsmåte b) fremstilles 2-iminopyridinderivatet med formel (II) som brukes som utgangsmateriale, med fordel in situ ved å behandle et passende substituert 2-aminopyri-salt med formel (VI) med en base. Hvis reaksjonen med cyanbromid utføres i nærvær av en organisk base som syrebindende komponent, bør 1 mol cyanbromid brukes for hvert mol 2-iminopyridinderivat med formel (II). Men hvis reaksjonen utføres uten noen syrebindende komponent, kan bare 0,5 mol av cyanbromid tilsettes for hvert mol av iminopyridinderivatet med formel (II). Denne reaksjonen utføres fortrinnsvis i et løsningsmiddel av ether-type. -Oppfinnelsen er illustrert i detalj ved hjelp av de følgende eksempler.
