Description
Fremgangsmåte til fremstilling av nye aminobenzensulfonsyreamid-derivater med langvarig terapeutisk virkning. Process for the production of new aminobenzenesulphonic acid amide derivatives with long-lasting therapeutic effect.
Foreliggende oppfinnelse angår en The present invention relates to a
fremgangsmåte til fremstilling av nye method for the production of new
aminobenzensulfonsyreamld-derivater med aminobenzenesulfonic acid amld derivatives with
langvarig terapeutisk virkning, og som til-svarer den generelle formel: long-lasting therapeutic effect, and corresponding to the general formula:
i hvilken R betegner en lavere alkylrest. in which R denotes a lower alkyl residue.
Det karakteristiske hovedtrekk ved fremgangsmåten består i at man på i og for The characteristic main feature of the procedure is that you put on and for
seg kjent måte enten omsetter itself known way either converts
a) forbindelser med den generelle for mel: i hvilken X betegner en aminogruppe eller en gruppe som kan omdannes til denne, n er tallene 0, 1 eller 2 og Y betegner et halogenatom, med 2-amino-5-lavere-al-koxy-pyrlmidiner, eller b) forbindelser med den generelle formel: i hvilken X har den ovenfor angitte betyd-ning, med 2-halogen-5-lavere-alkoxy-py-rimidiner, eller c) alkalisalter av syreamider av forbindelser med den generelle formel III med 2-trimetylammonium-5-lavere-alkoxy-pyrimidiinsalter, eller d) forbindelser med den generelle for mel: i hvilken X har den ovenfor angitte be-tydning, med forbindelser med den generelle formel: a) connections with the general for flour: in which X denotes an amino group or a group which can be converted into this, n is the number 0, 1 or 2 and Y denotes a halogen atom, with 2-amino-5-lower-alkoxy-pyrlmidines, or b) compounds with the general formula: in which X has the above-mentioned meaning, with 2-halo-5-lower-alkoxy-pyrimidines, or c) alkali salts of acid amides of compounds of the general formula III with 2-trimethylammonium-5-lower-alkoxy- pyrimidine salts, or d) compounds with the general for flour: in which X has the meaning given above, with compounds of the general formula:
i hvilken R har den ovenfor angitte be-tydning, Z og Z' betegner hydrogen eller in which R has the above meaning, Z and Z' denote hydrogen or
OR', hvor R' betegner like eller forskjellige OR', where R' denotes same or different
alkylgrupper, hvorved aldehydet også kan alkyl groups, whereby the aldehyde can also
foreligge i form av funksjonelle derivater og ringslutning foretas på i og for seg kjent exist in the form of functional derivatives and circularization is carried out in a manner known per se
måte, med påfølgende utbytting av eventu-elle hydroxylgrupper i 4- og/eller 6-stilling i pyrimidinringen med hydrogen og at man om nødvendig, på i og for seg kjent måte oxyderer de oppnådde forbindelser til benzensulfonsyreamidderivater, og når X ikke er en aminogruppe, omdanner X til en slik gruppe. manner, with subsequent replacement of any hydroxyl groups in the 4- and/or 6-position in the pyrimidine ring with hydrogen and that if necessary, in a manner known per se, the obtained compounds are oxidized to benzenesulfonic acid amide derivatives, and when X is not an amino group , transforms X into such a group.
Således fremstillede 2-sulfanylamido-5-lavere-alkoxy-pyramidiner tilhører grup-pen av de sterkt aktive benzensulfonamider av pyrimldinrekken og skiller seg fra de kjente representanter for denne gruppe ved substitusjon av pyrimidinringen i 5-stillin-genmed en alkoxygruppe, f. eks. en metoxygruppe eller en etoxygruppe. Der ble funnet at de forbindelser som fåes ved fremgangsmåten ifølge oppfinnelsen har like god virkning som de mest kjente representanter for ovennevnte og lignende grup-per av sulfonamider, og dette både med hensyn til anvendelsesområde og virkningens styrke. Thus prepared 2-sulfanylamido-5-lower-alkoxy-pyramidines belong to the group of the highly active benzenesulfonamides of the pyrimidine series and differ from the known representatives of this group by substitution of the pyrimidine ring in the 5-stilline gene with an alkoxy group, e.g. . a methoxy group or an ethoxy group. It was found that the compounds obtained by the method according to the invention have as good an effect as the best-known representatives of the above-mentioned and similar groups of sulfonamides, and this both with regard to the area of application and the strength of the effect.
Dette viste seg i en rekke sammen-lingningsforsøk med (2-p-aminobenzensul-fonamido)-pyrimidin (Sulfadiazin) som er den aktive bestanddel i mange kjente lege-midler, samt med det terapeutisk aner-kj ente 2 -sulf anilamido-5-etyl-tiodiazol-(1, 3, 4). Forsøkene ble utført in vitro ved hjelp av platefortynningsprøven og med antagonistfri busam-agar (2 pst. kjøtt-hydrolysat «Busam», 1 pst. dekstrose, 0,5 pst. natriumklorid og agar) med en tilsetning av 5 pst. hesteblod. Sulfonamidkon-sentrasjonene i platene var 1 : 10 000, 1 : 30 000, 1 : 100 000, 1 : 300 000, 1 : 1 000 000. 10 podningsstreker ble påført hver plate av de bakterier som er angitt i det følgende. This was shown in a series of comparison experiments with (2-p-aminobenzenesulfonamido)-pyrimidine (Sulfadiazine), which is the active ingredient in many known medicines, as well as with the therapeutically well-known 2-sulfanilamido-5 -ethyl-thiodiazole-(1, 3, 4). The experiments were carried out in vitro using the plate dilution test and with antagonist-free Busam agar (2% meat hydrolyzate "Busam", 1% dextrose, 0.5% sodium chloride and agar) with the addition of 5% horse blood. The sulfonamide concentrations in the plates were 1:10,000, 1:30,000, 1:100,000, 1:300,000, 1:1,000,000. 10 streaks were applied to each plate of the bacteria indicated below.

I samenligning med sulfonamider av tilsvarende . sterk virkning ligger giftig-heten i samme størrelsesorden. In comparison with sulfonamides of equivalent . strong effect, the toxicity is in the same order of magnitude.
I sammenligning med ikke alkoxylerte pyrimidinforbindelser viste forbindelser fremstillet ifølge oppfinnelsen den sær-lige fordel at der ved anvendelse på men-nesker ble oppnådd en særlig høy konsentrasjon i blodet som ble opprettholdt i overraskende lang tid. Allerede ved anvendelse av 1 g av natriumsaltet av 2-sulfanilamido-metoxy-pyrimidin per os ble der oppnådd en konsentrasjon i blodet som efter 4—8 timer gjennomsnittlig var mellom 4 og 5 mg pr. 100 ml. Ved intravenøs anvendelse ble der efter 1 time fastslått en konsentrasjon i blodet på 5 mg pr. 100 ml. Efter 24 timer lå konsentrasjonen i blodet i alle de ut-forsøk over 3 mg pr. 100 ml., tildels på 4 mg pr. 100 ml. In comparison with non-alkylated pyrimidine compounds, compounds produced according to the invention showed the particular advantage that, when applied to humans, a particularly high concentration was achieved in the blood which was maintained for a surprisingly long time. Even when using 1 g of the sodium salt of 2-sulfanilamido-methoxy-pyrimidine per os, a concentration in the blood was achieved which after 4-8 hours averaged between 4 and 5 mg per 100 ml. When administered intravenously, after 1 hour a concentration in the blood of 5 mg per 100 ml. After 24 hours, the concentration in the blood in all the experiments was above 3 mg per 100 ml., partly at 4 mg per 100 ml.
Til videre samenligning anføres at der med det kjemisk nærmeststående sulfon-amid, nemlig 2-sulfanilamido-pyrimidln, ble oppnådd en like høy konsentrasjon i blodet (på noget over 4 mg pr. 100 ml) først efter peroral anvendelse av 3 doser på 1 g, og at konsentrasjonen allerede efter 20 timer var sunket til 2 mg pr. 100 ml. For further comparison, it is stated that with the chemically closest sulfonamide, namely 2-sulfanilamido-pyrimidin, an equally high concentration in the blood (somewhat over 4 mg per 100 ml) was achieved only after oral administration of 3 doses of 1 g , and that the concentration had already dropped to 2 mg per 20 hours. 100 ml.
Utskillelse av 2-sufanilamido-5-metoxy-pyrimidin i urinen foregår tilsvarende lang-somt. Den er både efter peroral og intrave-nøs anvendelse av 1 g av stoffet efter 24 timer mindre en 30 pst. av den anvendte dose. Herav er bare en liten del acetylert. Excretion of 2-sufanilamido-5-methoxy-pyrimidine in the urine takes place correspondingly slowly. It is both after oral and intravenous use of 1 g of the substance after 24 hours less than 30 per cent of the dose used. Of this, only a small part is acetylated.
Nettopp i den senere tid vender inte-ressen seg mere og mere mot sulfonamider med langvarig virkning for å innskrenke de besværlige gjentagelser av dosene med korte tidsintervaller som nu brukes i tera-pien og er nødvendige for opprettholdelse av en aktiv konsentrasjon av preparatene i blodet, til et mindre antall doser som kan gis med større tidsintervaller mellom hver dose. Det var på ingen måte å forutse at innføringen av en alkoxygruppe i 5-stillingen i pyrimidinringen av 2-sulfanilami-dopyrimidin ville forårsake en slik forlengelse av virkningens varighet. Det er særlig overraskende at denne forlengelse av virkningens varighet ikke ledsages av nogen nedsettelse av virkningens styrke, særlig når man tar hensyn til at man hit-til har forsøkt et stort antall substitusjo-ner i denne pyrimidinkjerne og at disse i de fleste tilfelle var forbundet med et tap av virkningen. Innføringen av en alkoxygruppe i 4-stilling og i 6-stilling er tidligere beskrevet, men var ledsaget av en så sterk nedsettelse av den bakteriosta-tiske virkning at vedkommende forbindelser syntes å være verdiløse for praktisk anvendelse. Sammenlign i denne forbindelse en offentliggjørelse i «Journal of Ameri-can Chemical Soc», 1947, Bd. 69, II, sider 3072—3078. Også forsøk som er utført av patentinnehaveren bekrefter at innførin-gen av en metoxygruppe i 4-stillingen og 6-stillingen i pyrimidinringen av 2-sulfanil-amidopyrimidin fører til en sterk nedsettelse av aktiviteten. Just recently, interest is turning more and more towards sulfonamides with a long-lasting effect in order to reduce the troublesome repetitions of the doses at short time intervals that are now used in therapy and are necessary to maintain an active concentration of the preparations in the blood, to a smaller number of doses that can be given with greater time intervals between each dose. It was by no means foreseeable that the introduction of an alkoxy group in the 5-position of the pyrimidine ring of 2-sulfanilamidopyrimidine would cause such a prolongation of the duration of action. It is particularly surprising that this extension of the duration of the effect is not accompanied by any reduction in the strength of the effect, especially when one takes into account that a large number of substitutions in this pyrimidine core have been tried so far and that these were in most cases connected with a loss of effectiveness. The introduction of an alkoxy group in the 4-position and in the 6-position has previously been described, but was accompanied by such a strong reduction in the bacteriostatic effect that the compounds in question appeared to be worthless for practical use. Compare in this connection a publication in the "Journal of American Chemical Soc", 1947, Vol. 69, II, pages 3072-3078. Experiments carried out by the patent holder also confirm that the introduction of a methoxy group in the 4-position and the 6-position in the pyrimidine ring of 2-sulfanyl-amidopyrimidine leads to a strong reduction in activity.
