Il I vf-y^R2 r1 25 hvori R1, R2 og R3 har ovennævnte betydninger, ved en temperatur mellem -10 og +100"C, fortrinsvis mellem +10 og +50°C, behandles med en alkalimetal- eller ammoniumbase sâsom na-triumhydroxid, kaliumhydroxid, natriumcarbonat, kaliumcar-bonat, ammoniak, eller et alkalimetal-(Ci_3)-alkoholat, 30 fortrinsvis natriummethylat eller -ethylat i et organisk oplosningsmiddel, fortrinsvis i en alkohol med 1-3 carbon-atomer eller i en keton med 3-5 carbonatomer, eventuelt under tilsætning af vand, eller med én af de nævnte baser i vand uden tilsætning af et organisk opl0sningsmiddel, og de 35 sâledes fremstillede alkalimetal- eller ammonium-forbindelser med formlen I eventuelt, hensigtsmæssigt i vandig opl0sning, 4

omsættes med en mineralsyre eller en stærk, organisk syre, hensigtsmæssigt med den i det mindste ækvimolære mængde af syren.
Til den ovenfor beskrevne fremstilling af alkalimetal-5 eller ammonium-forbindelserne med formlen I anvendes de nævnte baser hensigtsmæssigt ækvimolært og ogsâ i ringe overskud, især i 1,1-1,3-molært overskud.
De som udgangsmateriale til fremstillingen af de her omhandlede forbindelser med formlen I anvendte 2-alkoxyme-10 thylenaceteddikesyreanilider med formlen IV er hidtil ukend-te.
Kun fremstillingen af det if0lge den foreliggende ansogning ikke anvendte 2-ethoxymethylenaceteddikesyreanilid af aceteddikesyreanilid, orthomyresyretriethylester og acet-15 anhydrid er beskrevet af G. Kempter, W. Schmidt og H. Dost,
Chem. Ber. 98, 955-961 (1965).
I tabel I er de nye 2-ethoxymethylenaceteddikesyre-anilider anfort.
Isoxazolerne med formlen V er ligeledes nye. Kun tre 20 analoge isoxazoler, hvor R1, R2 og R3 betyder hydrogen, eller R1 og R2 betyder hydrogen, og R3 betyder 2-CH3 eller 4-CH3, er beskrevet af F.B. Dains og E. L. Griffin, J. Am.
Chem. SOC. 35, 959-976 (1913).
Reaktionstrinnet fra en forbindelse med formlen IV 25 til en forbindelse med formlen V er overraskende. Det omfat-ter cyclisering af de let tilgængelige 2-ethoxymethylenacet-eddikesyreanilider med hydroxylamin til isoxazolerne med formlen V, der allerede ved stuetemperatur forldber i udbyt-ter mellem 90 og 100%.
30 De syntetiserede isoxazoler er sammenfattet i tabel II.
Den ovenfor forklarede ringâbning af isoxazolerne med formlen V til 2-hydroxyethylidencyaneddikesyreaniliderne med formlen I med baser forl0ber praktisk tait kvantitativt.
35 De nye slutprodukter er sammenfattet i tabel III.
De her omhandlede forbindelser med formlen I udviser 5
DK 157078 B
stærke antiphlogistiske og analgetiske egenskaber. Deres an-tiphlogistiske og analgetiske virkning er stærkere end phe-nylbutazons virkning.
De her omhandlede forbindelser med formlen I udviser 5 i det terapeutiske dosisomrâde ingen ulcerogene virkninger.
Den antiphlogistiske virkning pâvises pâ adjuvans-arthritis hos rotter (Pearson, C. M. og Wood, F. D., Arthrit. Rheumat. 2 (1959), 440) og den analgetiske virkning ved et Writhing-forsog med mus (Sigmund, E. et al., Proc. Soc.
10 Exp. Biol. Med. 95 (1957), 729).
ED50-værdierne bestemmes grafisk i et sandsynligheds-net. Ved Writhing-forsbget defineres ED5Q-værdien ved den præparatdosis, der i forhold til kontrolværdien nedsætter antallet af sl0jfebevægelser med 50%. Ved adjuvans-arthritis-15 fors0get bed0mmes virkningen ved den pâ den 17. dag efter begyndelsen af præparatindgiften i forhold til kontrolgruppen iagttagne hæmning af de sekundære læsioner pâ dyrenes 0rer, poter og haie. Som ED50-værdi gælder den dosis, der for-mindsker disse læsioner med 50% i forhold til kontrolgruppen.
20 Til undersegelse af den ulcerogene virkning indgives prevesubstanserne oralt til hanrotter af en Sprague-Dawley-stamme, der har fastet i 18 timer, og 24 timer derefter unders0ges dyrenes mave-tarmomrâde for ulcéra.
Ved den akutte toksicitetsundersdgelse if0lge Litch-25 field og Wilcoxon (Litchfield, J. T. og Wilcoxon, F. W., J. Pharmacol, exp. Ther. 96 (1949), 99) sker bestemmelsen af LD5Q-værdierne pâ han- eller hun-N.M.R.I.-mus eller pâ Wi-star-Lewis-hunrotter.
De konstaterede værdier for nogle forbindelser med 30 formlen I og det kendte phenylbutazon er angivet i nedenstâ-ende tabel IV.
