Description
Fremgangsmåte til fremstilling av nye, diuretisk aktive sulfamyl-antranilsyre-forbindelser. Process for the production of new, diuretically active sulfamyl-anthranilic acid compounds.
Foreliggende oppfinnelse angår fremgangsmåter til fremstilling av nye antranilsyre-forbindelser som har en sulfamyl-substituent bundet til et av kullstoff-atomene i kjernen. De forbindelser som fremstilles ifølge oppfinnelsen har følgende generelle formel: The present invention relates to methods for the production of new anthranilic acid compounds which have a sulfamyl substituent bound to one of the carbon atoms in the nucleus. The compounds produced according to the invention have the following general formula:
i hvilken Ri betegner halogen, en lavere alkylrest, en aminogruppe, en lavere al-koxygruppe eller en nitrogruppe, R2 betegner hydrogen eller en lavere alkylgrup- in which Ri denotes halogen, a lower alkyl radical, an amino group, a lower alkoxy group or a nitro group, R 2 denotes hydrogen or a lower alkyl group-
pe, Y betegner hydrogen, en lavere alkylgruppe, en alkanoylgruppe med fra 2 til 12 kullstoffatomer eller et benzoylradikal og Rc betegner en karboxylgruppe, en lavere alkoxykarhonylgruppe, eller en eventuelt med lavere alkyl mono- eller disubstituert karbamylgruppe, idet hver alkylsubstituent fortrinsvis har fra 1 til 3 kullstoffatomer. pe, Y denotes hydrogen, a lower alkyl group, an alkanoyl group with from 2 to 12 carbon atoms or a benzoyl radical and Rc denotes a carboxyl group, a lower alkoxycarhonyl group, or an optionally lower alkyl mono- or disubstituted carbamyl group, each alkyl substituent preferably having from 1 to 3 carbon atoms.
Oppfinnelsen omfatter også fremstil- The invention also includes manufacturing
ling av alkalimetallsaltene og jordalkalimetallsaltene av forbindelser som ovenfor angitt. ling of the alkali metal salts and the alkaline earth metal salts of compounds as indicated above.
De nye forbindelser som fremstilles The new compounds that are produced
ifølge oppfinnelsen er fordelaktige terapeu- according to the invention, advantageous therapeutic
tiske midler særlig på grunn av deres diuretiske, natriuretiske og/eller saluretiske egenskaper (som i det følgende alle vil bli tical agents especially because of their diuretic, natriuretic and/or saluretic properties (which in the following will all be
betegnet med diuretiske egenskaper). Da forbindelsene er aktive ved oral anvendelse kan de gis i terapeutiske doser sammen med vanlige bærere, f. eks. i form av tabletter, piller, kapsler og lignende. Forbindelsene er også oppløselige i fortynnede alkaliske medier og i polyetylenglykol. In-jiserbare oppløsninger kan derfor frem- denoted by diuretic properties). Since the compounds are active when used orally, they can be given in therapeutic doses together with common carriers, e.g. in the form of tablets, pills, capsules and the like. The compounds are also soluble in dilute alkaline media and in polyethylene glycol. Injectable solutions can therefore produce
stilles av dem for parenteral anvendelse ved å oppløse forbindelsene i et passende medium og, om ønskes, tilsette konser-verende midler til de erholdte oppløsnin- prepared by them for parenteral use by dissolving the compounds in a suitable medium and, if desired, adding preservatives to the solutions obtained
ger. gives.
Doser av forbindelsene på mellom om- Doses of the compounds at between om-
kring 5 og omkring 10 mg pr. døgn pr. kilo legemsvekt er i alminnelighet passende til frembringelse av en diuretisk reaksjon. Selvfølgelig kan der anvendes større eller mindre doser av det aktive stoff i avhen-gighet av pasientens alder og hans til-stand. Av denne grunn kan der leveres til legen tabletter inneholdende 0,5 g eller mere av det aktive stoff og som er for- around 5 and around 10 mg per day per kilogram of body weight is generally suitable for producing a diuretic reaction. Of course, larger or smaller doses of the active substance can be used depending on the patient's age and his condition. For this reason, tablets containing 0.5 g or more of the active substance can be delivered to the doctor and which are
synt med innsnitt for oppdeling. Slike doser viser seg å ligge godt under forbin-delsenes giftige dose hva der fremgår av den kjennsgjerning at dosen for en akutt dødelighet på 50 pst. (LDso) ved anvendelse på mus av forbindelsene 2-karboxy-5-klor-4-sulfamylacetanilid og 2-karboxy-5-klor-4-sulfamylanilin er større enn 600 mg pr. sinte with incisions for division. Such doses turn out to be well below the toxic dose of the compounds, which is evident from the fact that the dose for an acute mortality of 50 percent (LDso) when applied to mice of the compounds 2-carboxy-5-chloro-4-sulfamylacetanilide and 2-carboxy-5-chloro-4-sulfamylaniline is greater than 600 mg per
kg legemsvekt, og at ingen toksiske reaksjoner ble observert når disse forbindelser ble gitt intravenøst til hunder i doser opp- kg body weight, and that no toxic reactions were observed when these compounds were given intravenously to dogs in doses up to
til 15 mg pr. kg legemsvekt. to 15 mg per kg body weight.
De diuretiske egenskaper hos de forbindelser som fremstilles ifølge oppfinnelsen gjør dem særlig fordelaktige til be-handling av kongestiv hjertesvikt og andre patologiske tilstander som frembringer ødemer i legemet, eller som forårsaker en forstyrrelse av ballansen i legemets elek-trolytkonsentrasjon som f. eks, de tilstander i hvilke der finner sted en abnorm reten-sjon av natrium. The diuretic properties of the compounds produced according to the invention make them particularly advantageous for the treatment of congestive heart failure and other pathological conditions which produce edema in the body, or which cause a disturbance of the balance in the body's electrolyte concentration, such as, for example, the conditions in which there is an abnormal retention of sodium.
De nye sulfamyl-antranilsyre-forbindelser som fremstilles ifølge oppfinnelsen er også fordelaktige som mellomprodukter ved fremstilling av 4-kinazolon-derivater som likeledes har diuretiske, natriuretiske og/eller saluretiske egenskaper. For fremstilling av 4-kinazolon oppvarmes i alminnelighet sulfamyl-antranilsyre-forbindelser fremstillet ifølge oppfinnelsen med formamid eller etylortoformiat. De sulfamyl-antranilsyre-forbindelser i hvilke kar-boxylgruppen er overført til en karbamylgruppe, og en acylgruppe er bundet til aminonitrogenet kan cykliseres til et 4-kinazolon ved oppvarming. The new sulfamyl-anthranilic acid compounds produced according to the invention are also advantageous as intermediates in the production of 4-quinazolone derivatives which likewise have diuretic, natriuretic and/or saluretic properties. For the production of 4-quinazolone, sulfamyl-anthranilic acid compounds prepared according to the invention are generally heated with formamide or ethyl orthoformate. The sulfamyl-anthranilic acid compounds in which the carboxyl group is transferred to a carbamyl group, and an acyl group is attached to the amino nitrogen can be cyclized to a 4-quinazolone by heating.
Ifølge oppfinnelsen kan de nye antranilsyre-forbindelser fremstilles ved én eller flere av de fremgangsmåter som er vist i følgende reaksjonsskjema. According to the invention, the new anthranilic acid compounds can be prepared by one or more of the methods shown in the following reaction scheme.
Den i reaksjonsskjemaet med III be-tegnede sulfamyl-antranilsyre-forbindelse kan fremstilles enten fra et 2-metylacyl-anilid I (a) eller fra antranilsyren, forbindelse I(b). Disse utgangsmaterialer er kjente forbindelser. Hvilken som helst av disse veier for syntesen kan anvendes i praktisk talt hvert tilfelle. Imidlertid foretrekkes det når Ri er et metylradikal, å bruke utgangsmaterialet I(b) for å unngå oxydasjon av metylradikalet når man overfører forbindelse II til forbindelse III. The sulfamyl-anthranilic acid compound designated III in the reaction scheme can be prepared either from a 2-methylacyl-anilide I (a) or from the anthranilic acid, compound I(b). These starting materials are known compounds. Any of these routes of synthesis can be used in virtually every case. However, when Ri is a methyl radical, it is preferred to use the starting material I(b) to avoid oxidation of the methyl radical when transferring compound II to compound III.
Som det sees av foranstående reaksjonsskjema utføres best fremstilling av sulfamyl-antranilsyreforbindelser i hvilke Y er hydrogen i den generelle formel, ved å hydrolysere forbindelse III så at N-acyl-gruppen fjernes, hvorved forbindelse IV dannes. Amidene av forbindelse IV kan da fremstilles ved først å fremstille sulfamyl-isatinsyreanhydridet VI ved å oppvarme sulfamyl-antranilsyren, forbindelse IV med det passende alkylhalogenkarbonat. Amidet fremstilles derpå av sulfamyl-isatin-syreanhydridet, VI, ved omsetning med ammoniakk eller et amin. As can be seen from the preceding reaction scheme, the best preparation of sulphamyl-anthranilic acid compounds in which Y is hydrogen in the general formula is carried out by hydrolysing compound III so that the N-acyl group is removed, whereby compound IV is formed. The amides of compound IV can then be prepared by first preparing the sulphamyl-isatinic anhydride VI by heating the sulphamyl-anthranilic acid, compound IV with the appropriate alkyl halide carbonate. The amide is then prepared from the sulfamyl isatin anhydride, VI, by reaction with ammonia or an amine.
Når det ønskes at Y i den generelle formel skal være en acyl-substituent, kan N-acylforbindelsen III overføres til syrekloridet og derpå behandles med ammoniakk eller et amin så at amidet dannes. When it is desired that Y in the general formula should be an acyl substituent, the N-acyl compound III can be transferred to the acid chloride and then treated with ammonia or an amine so that the amide is formed.
Når RL. og Y i den generelle formel begge skal være et alkylradikal, fremstilles forbindelsene ved alkylering av den passende 2-metyl- eller 2-karboxy-N-alkyl-anilin-forbindelse, og forbindelsene I (a) eller I(b) betyr de disse dialkylaniliner i de her beskrevne reaksjoner. When RL. and Y in the general formula shall both be an alkyl radical, the compounds are prepared by alkylation of the appropriate 2-methyl- or 2-carboxy-N-alkyl-aniline compound, and the compounds I (a) or I(b) mean those dialkylanilines in the reactions described here.
Overføring av 2-metylanilin, forbindelse I(a), til 2-metylsulfamylanilin, forbindelse II, utføres ved først å klorsulfonere forbindelse I (a) med klorsulfonsyre, idet man fordelaktig bruker et overskudd på en molekvivalent av denne syre og fortrinnsvis oppvarmer reaksjonsblandingen til omkring 60—100° C. Transfer of 2-methylaniline, compound I(a), to 2-methylsulfamylaniline, compound II, is carried out by first chlorosulfonating compound I (a) with chlorosulfonic acid, advantageously using an excess of one molar equivalent of this acid and preferably heating the reaction mixture to around 60-100° C.
Sulfonylkloridderivatet av I (a) behandles derpå med ammoniakk, fortrinnsvis ved en temperatur mellom omkring 0° C og romtemperatur, hvorpå man oppvarmer reaksjonsblandingen fortrinnsvis på dampbad, hvorved 2-metyl-4-sulfamylanilin, forbindelse II dannes. The sulphonyl chloride derivative of I (a) is then treated with ammonia, preferably at a temperature between about 0° C and room temperature, after which the reaction mixture is heated, preferably on a steam bath, whereby 2-methyl-4-sulfamylaniline, compound II is formed.
Ammoniakken som brukes i amide-ringstrinnet anvendes i overskudd over den mengde som kreves for å overføre sulfonylkloridgruppen til sulfamylgruppen. Fortrinnsvis brukes der minst to molekvi-valenter ammoniakk. Ammoniakken kan tilsettes i form av vandig eller alkoholisk ammoniumhydroxyd eller som flytende ammoniakk. Man kan også oppløse sulfo-nylkloridet i et organisk oppløsningsmiddel og boble ammoniakkgass gjennom oppløs-ningen for å danne sulfamylderivatet. The ammonia used in the amidation step is used in excess over the amount required to transfer the sulfonyl chloride group to the sulfamyl group. Preferably, at least two molecular equivalents of ammonia are used there. The ammonia can be added in the form of aqueous or alcoholic ammonium hydroxide or as liquid ammonia. One can also dissolve the sulfonyl chloride in an organic solvent and bubble ammonia gas through the solution to form the sulfamyl derivative.
2-metylgruppen i 2-metyl-4-sulfamylanilin, forbindelse II, oxyderes derpå til en karboxylgruppe, fortrinnvis ved å oppvarme til omkring 100° C en reaksjons-blanding som. inneholder forbindelse II, kaliumpermanganat og magnesiumsulfat. Reaksjonsblandingen holdes fortrinsvis på en pH-verdi nær nøytralpunktet for å unngå fjernelse av N-acylradikalet og reaksjonen fortsettes inntil permanganatets ka-rakteristiske farve forsvinner. The 2-methyl group in 2-methyl-4-sulfamylaniline, compound II, is then oxidized to a carboxyl group, preferably by heating to about 100° C. a reaction mixture which. contains compound II, potassium permanganate and magnesium sulfate. The reaction mixture is preferably kept at a pH value close to the neutral point to avoid removal of the N-acyl radical and the reaction is continued until the characteristic color of the permanganate disappears.
Som ovenfor nevnt kan den foran beskrevne reaksjon til overføring av forbindelse I (a) til forbindelse III utføres med hvilken som helst av de mellomprodukter som kreves for å fremstille sulfamyl-antranilsyre-forbindelsen. Når Ri er et metylradikal, foretrekkes det imidlertid å bruke et utgangsmateriale av den type som vises ved formelen I(b) i reaksjonsskjemaet. I de tilfelle hvor N-acylderiva-tet av forbindelse I (a) eller I(b) ikke er lett tilgjengelig, kan dette fremstilles av den passende anilinforbindelse ved hjelp av kjente acyleringsmetoder. As mentioned above, the above-described reaction to transfer compound I (a) to compound III can be carried out with any of the intermediates required to prepare the sulfamyl-anthranilic acid compound. When Ri is a methyl radical, however, it is preferred to use a starting material of the type shown by formula I(b) in the reaction scheme. In those cases where the N-acyl derivative of compound I (a) or I (b) is not readily available, this can be prepared from the appropriate aniline compound by means of known acylation methods.
Hvilken som helst av de beskrevne sulfamyl-antranilsyre-forbindelser og særlig den i hvilke Ri er en metylgruppe, kan fremstilles fra N-acylantranil-syrene, I(b). Any of the described sulphamyl-anthranilic acid compounds and especially the one in which Ri is a methyl group, can be prepared from the N-acylanthranilic acids, I(b).
Klorsulfoneringen og amideringen av forbindelse I(b) så at forbindelsene III eller IV dannes, utføres i det vesentlige på den måte som er beskrevet foran for over-føring av 2-metylanilin-forbindelsen, I (a), til 2-metylsulfamylanilin-forbindelsen, II. The chlorosulfonation and amidation of compound I(b) to form compounds III or IV is carried out essentially in the manner described above for the conversion of the 2-methylaniline compound, I(a), to the 2-methylsulfamylaniline compound , II.
Forbindelse III kan derpå hydrolyseres til sulfamyl-antranilsyren, forbindelse IV, ved hvilken som helst av de vanlige metoder, f. eks. ved å oppvarme på dampbad i nærvær av saltsyre eller ved å oppvarme under tilbakeløpskj øling en blanding av forbindelse III, alkohol og konsentrert saltsyre. Compound III can then be hydrolysed to the sulfamyl-anthranilic acid, compound IV, by any of the usual methods, e.g. by heating on a steam bath in the presence of hydrochloric acid or by heating under reflux a mixture of compound III, alcohol and concentrated hydrochloric acid.
Amidene av de sulfamyl-antranilsyrer hvor Y er hydrogen og R(; er karboxylgrup-pen kan fremstilles av forbindelse IV. Amidderivatene av forbindelse IV fremstilles ved å oppvarme 2-karboxy-sulfamylanilin, forbindelse IV, med et alkyl-halo-genkarbonat så at der dannes sulfamyl-isatinsyreanhydrid, VI, og (2-karbalkoxy-sulfamylfenyl) -alkylkarbamat, forbindelse A. Forbindelsene IV og A kan skilles fra hverandre ved å dra fordel av deres forskjellige oppløselighet i dioxan. Sulfamyl-isatinsyreanhydridet, VI, som er uoppløse-lig i dioxan, fraskilles da og omsettes med ammoniakk eller et amin, hvorved der dannes en blanding av 2-karbamyl-sulfamylanilin, VII, og (2-karboxy-sulfamyl-fenyl)-urinstoff, B. De to sistnevnte forbindelser kan skilles fra hverandre ved hjelp av deres forskjellige oppløselighet i vandig ammoniakk, idet forbindelse VII er uoppløselig og kan oppsamles ved vel-kjente forholdsregler som f. eks. ved filtrering. Amidering av forbindelse VI utføres fordelaktig ved å omrøre eller ryste en blanding av denne forbindelse og ammoniakk. Ammoniakken kan brukes i forskjellige former som i form av vandig eller alkoholisk ammoniakk, flytende ammoniakk eller ammoniakkgass. I stedet for ammoniakk kan man også bruke et passende amin. Omrøringen eller rystningen foregår ved romtemperatur eller ganske lite høyere temperaturer i 5—8 timer. Overskuddet av ammoniakk eller amin fjernes derpå i vakuum. Der kan brukes minst to ekviva-lenter ammoniakk eller amin. I praksis brukes der i alminnelighet et overskudd da dette ikke innvirker på reaksjonen og om-kostningene dermed ikke er bemerkelses-verdig store. The amides of the sulfamyl-anthranilic acids where Y is hydrogen and R(; is the carboxyl group can be prepared from compound IV. The amide derivatives of compound IV are prepared by heating 2-carboxy-sulfamylaniline, compound IV, with an alkyl halocarbonate so that there is formed sulfamyl-isatinic anhydride, VI, and (2-carbalkoxy-sulfamylphenyl)-alkylcarbamate, compound A. Compounds IV and A can be separated by taking advantage of their different solubilities in dioxane. The sulfamyl-isatinic anhydride, VI, which is insoluble -lig in dioxane, is then separated and reacted with ammonia or an amine, whereby a mixture of 2-carbamyl-sulfamylaniline, VII, and (2-carboxy-sulfamyl-phenyl)-urea, B, is formed. The latter two compounds can be separated from each other by means of their different solubilities in aqueous ammonia, compound VII being insoluble and can be collected by well-known precautions such as filtration Amidation of compound VI is advantageously carried out by stirring el lets shake a mixture of this compound and ammonia. The ammonia can be used in different forms such as aqueous or alcoholic ammonia, liquid ammonia or ammonia gas. Instead of ammonia, a suitable amine can also be used. The stirring or shaking takes place at room temperature or slightly higher temperatures for 5-8 hours. The excess of ammonia or amine is then removed under vacuum. At least two equivalents of ammonia or amine can be used. In practice, a surplus is generally used as this does not affect the reaction and the costs are thus not remarkably large.
Karboxamidene av forbindelse III, dvs. 2-karboxy-sulfamylacylanilidene, og karboxamidene av 2-karboxy-sulfamyl-N-al-kylanilin og av 2-karboxy-sulfamyl-N,N-dialkylanilin, fremstilles under anvendelse av den på passende måte substituerte sulfamyl-antranilsyre og ved å overføre denne til syrekloridet med et kloreringsmiddel. Som sådant kan brukes fosforpentaklor, fosfortriklorid, tionylklorid, sulfurylklorid eller lignende. Kloreringen utføres fortrinnsvis ved romtemperatur eller litt høy-ere temperatur. Reaksjonen finner sted i nærvær av et oppløsningsmiddel som benzen, toluen, dioxan eller lignende. Det således erholdte antranilsyreklorid behandles med ammoniakk eller et amin, hvorved karbamylderivatet, VIII, dannes. Der kan brukes ammoniakk i praktisk talt hvilken som helst form, således i de foran nevnte former, med eller uten et oppløsningsmid-del og fortrinnsvis ved romtemperatur. Når det brukes et amin utføres reaksjonen fortrinnsvis i nærvær av et oppløsningsmiddel og ved romtemperatur eller litt høyere temperaturer. Uansett om ammoniakk eller et amin brukes til å danne karbamylderivatet VIII, anvender man minst to ekviva-lenter. Imidlertid kan et overskudd brukes og dette gjøres i alminnelighet da det ikke på noen måte innvirker på amidering av antranilsyrekloridet med godt resultat. The carboxamides of compound III, i.e., the 2-carboxysulfamylacylanilides, and the carboxamides of 2-carboxysulfamyl-N-alkylaniline and of 2-carboxysulfamyl-N,N-dialkylaniline are prepared using the appropriately substituted sulphamyl-anthranilic acid and by transferring this to the acid chloride with a chlorinating agent. As such, phosphorus pentachlor, phosphorus trichloride, thionyl chloride, sulfuryl chloride or the like can be used. The chlorination is preferably carried out at room temperature or a slightly higher temperature. The reaction takes place in the presence of a solvent such as benzene, toluene, dioxane or the like. The anthranilic acid chloride thus obtained is treated with ammonia or an amine, whereby the carbamyl derivative, VIII, is formed. Ammonia can be used in practically any form, thus in the aforementioned forms, with or without a solvent and preferably at room temperature. When an amine is used, the reaction is preferably carried out in the presence of a solvent and at room temperature or slightly higher temperatures. Regardless of whether ammonia or an amine is used to form the carbamyl derivative VIII, at least two equivalents are used. However, an excess can be used and this is generally done as it does not in any way interfere with the amidation of the anthranilic acid chloride with good results.
Esterne av forbindelse III eller forbindelse IV fremstilles fordelaktig ved å om-sette vedkommende sulfamylantranilsyre, III eller IV, med en alkohol som har fra 1 til 5 kullstoffatomer i molekylet, i nærvær av hydrogenklorid. Herved dannes en forbindelse V i hvilken Y er hydrogen eller et alkyl- eller acylradikal. The esters of compound III or compound IV are advantageously prepared by reacting the sulphamylanthranilic acid in question, III or IV, with an alcohol having from 1 to 5 carbon atoms in the molecule, in the presence of hydrogen chloride. This creates a compound V in which Y is hydrogen or an alkyl or acyl radical.
Alkalimetallsaltene av sulfamyl-antranilsyre-forbindelsene kan fremstilles ved hvilke som helst av de vanlige metoder, som det å oppløse vedkommende sulfamyl-antranilsyre-forbindelse i en vandig eller alkoholisk oppløsning av vedkommende al-kaiimetallhydroxyd. Om så ønskes, kan saltet derpå isoleres ved å fordampe opp-løsningen. Ved hjelp av denne metode kan der fremstilles hvilken som helst av de vanlige alkalimetallsalter som natrium-, kalium- eller litiumsaltet. Til fremstilling av saltene kan der også brukes andre metoder som er kjent i den organiske kjemi. Jordalkalimetallsaltene fremstilles ved å erstatte alkalimetallet i alkalimetallsaltene med et jordalkalimetall ved hjelp av vel-kjente fremgangsmåter. The alkali metal salts of the sulfamyl-anthranilic acid compounds can be prepared by any of the usual methods, such as dissolving the sulfamyl-anthranilic acid compound in question in an aqueous or alcoholic solution of the alkali metal hydroxide in question. If desired, the salt can then be isolated by evaporating the solution. By means of this method, any of the usual alkali metal salts such as the sodium, potassium or lithium salt can be produced. For the preparation of the salts, other methods known in organic chemistry can also be used.
