Abstract
"Analogifremgangsmåte for fremstilling av farmakologisk aktive N-pyrimidinyl-imidsyreestere"
Description
Denne oppfinnelse angår fremstilling av nye imidsyreestere med formel I
12 3
hvor R , R og R , som kan være like eller forskjellige fra hver-
4
andre, betyr hydrogen, metyl, metoksy eller klor, R betyr hydrogen eller alkyl med 1-4 C-atomer, R 5betyr alkyl med 1-6 C-atomer eller benzyl, og R betyr alkyl med 1-4 C-atomer eller benzyl, og n er 0 eller 1.
Fortrinnsvis står substituentene R 1, R 2 og R 3i 3-,
4- og 5-stilling i benzenringen.
Blant forbindelsene med formel I foretrekkes de hvor R<4>betyr hydrogen eller etyl.
De nye forbindelser med formel I foretas ved metoder som er vanlige for fremstilling av imidsyreestere, slik som bl.a. beskrevet i Houben-Weyl "Methoden der organischen Chemie",
bind 6/3, og i henhold til oppfinnelsen omsettes en forbindelse med formel II
12 3 4 hvor R , R , R , R og n har de ovenfor angitte betydninger, med en ortokarboksylsyreester med formel III
5 6
hvor R og R har de ovenfor angitte betydninger.
Fremstillingen av forbindelsene med formel I kan foretas med eller uten oppløsningsmiddel, idet man i sistnevnte tilfelle arbeider med et overskudd av den anvendte brtokarboksylsyreester. Som mulige oppløsningsmidler kan hensiktsmessig for eksempel anvendes dimetylformamid eller dioksan. Reaksjonstemperaturene ligger mellom 0 og 150°C, fortrinnsvis mellom 50 og 100°C rsp. ved temperaturer opp til kokepunktet for det anvendte oppløsnings-middel eller ortokarboksylsyreesteren. Omsetningen kan eventuelt foretas i nærvær av katalytiske mengder av en syre, for eksempel saltsyre.
Hvis man for eksempel anvender 2,4-diamino-5-(3,4,5-trimetoksybenzyl)-pyrimidin og ortoeddiksyretrietylester som utgangsstdffer, kan reaksjonsforløpet gjengis ved følgende formel-skj erna:
De nye forbindelser med formel I er antibakterielt aktive ved sykdommer fremkalt'av bakterier og protozoer, og forsterker, kombinert med sulfonamider, . deres antimikrobielle virkning. De kan således for eksempel anvendes ved bakterielle sykdommer i åndedrettsorganene, fordøyelsesorganene og urinveiene så vel som ved hals-, nese- og øreinfeksjoner og generelle systemiske infek-sjoner og ved malaria.
Egnede sulfonamider er for eksempel: 2-sulfanilamido-pyridin, 2-sulfanilamido-tiazol, 2-sulfanilamido-pyrimidin, 2-sulfanilamido-4-metyl-pyrimidin, 2-sulfanilamido-4,6-dimetyl-pyrimidin, 4-sulfanilamido-2,6-dimetyl-pyrimidin, 5-sulfanilamido-3,4-diraetyl-isoksazol, 3-sulfanilamido-6-metoksy-pyridazin, 3-sulfanilamido-6-klor-pyridazin, 4-sulfanilamido-2,6-dimetoksy-pyrimidin, 3-sulfanilamido-2-fenyl-pyrazol, 2-sulfanilamido-5-metyl-pyrimidin, 2-sulfanilamido-5-metoksy-pyrimidin, 2-sulfanilamido-5-metyl-isoksazol, 2-sulfanilamido-4,5-dimetyl-oksazol, 2-sulfanilamido-3-metoksy-pyrazin, 4-sulfanilamido-5,6-dimetoksy-pyrimidin, 4-sulfanilamido-3-metoksy-1,2,5-tiådiazol, 4-aminobenzol-sulfonyl-guanidin.
Forbindelsene med formel I kan blandes med for eksempel de nevnte sulfonamider i forskjellige blandingsforhold, hvor forholdet mellom forbindelsen med formel I og sulfonamid kan variere fra 1:10 til 5:1. Foretrukne mengdeforhold er 1:1 til 1:5. Vanligvis anvendes en dosering på 20 til 500. mg av en aktiv forbindelse med formel I.
For påvisning av virkningen ble de nye forbindelser undersøkt ved dyreforsøk efter modell av den såkalte Aronson-Sepsis, hvor infisering foretas med Streptococcus agalactiae,<p>g sammenligning ble gjort med den kjente forbindelse trimetoprim. For dette formål ble grupper på hver '30 hunnmus infisert med en dødelig dose av Streptococcus agalactiae 7941 og behandlet 2 timer efter infeksjonen med en blanding av 300 mg 2-sulfanilamido-4,5-dimetyl-oksazol + 60 mg av en av forbindelsene fremstilt ifølge oppfinnelsen. Foruten en ubehandlet kontrollgruppe ble en annen gruppe behandlet med en blanding av 300 mg 2-sulfanilamido-4,5-dimetyloksazol + 60 mg trimetoprim som tjente som referansestoff. Efter 44 timer ble antall overlevende dyr be-stemt, og dette tall ble dividert med det antall overlevende dyr i den gruppe som var behandlet med referansestoffet. Den således oppnådde tallverdi (trimetoprimfaktor) er et mål for virkningen av de nye forbindelser sammenlignet med trimetoprim.
F = 2 betyr således at'forbindelsen er dobbelt så aktiv som trimetoprim. Av den følgende tabell fremgår det at de nye forbindelser er opptil 5 ganger så aktive som trimetoprim.
Forbindelsene fremstilt ifølge oppfinnelsen kan anvendes i kjemoterapeutiske midler som ved siden av vanlige bære- og fortynningsmidler inneholder en forbindelse med formel I, spesi-elt i kombinasjon med et sulfonamid, som aktive stoffer.
De kjemoterapeutiske midler rsp. preparater fremstilles med de vanlige bærestoffer eller fortynningsmidler og de vanlig anvendte farmasøytisk-tekniske hjelpestoffer i henhold til den ønskede administreringsform.
De foretrukne preparater består av en tilberedelsesform som er egnet for oral administrering. Slike tilberedelsesformer er f.eks. tabletter, filmtabletter, dragéer, kapsler, piller, pulvere, oppløsninger eller suspensjoner.
