Description
Verfahren zur Herstellung von neuen N'-substituierten N-Arylsulfonylharnstoffen
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von neuen N'-substituierten N-Arylsulfonylharnstoffen.
Verbindungen der allgemeinen Formel I,
EMI1.1
in welcher R1 Wasserstoff, Halogen bis Atomnummer 35, eine niedere Alkyl-, Alkoxy-, Alkylthio- oder Alka noylgruppe oder die Aminogruppe, R2 Wasserstoff oder R1 R. die Trimethylen- oder die Tetramethylengruppe be deutet, sowie ihre Salze mit anorganischen oder organischen Basen sind bisher nicht bekannt geworden.
Wie nun gefunden wurde, besitzen die neuen Verbindungen sowie ihre pharmazeutisch annehmbaren Salze wertvolle pharmakologische Eigenschaften. Sie zeigen überraschenderweise bei peroraler oder parenteraler Verabreichung hypoglykämische Wirkung, die sie als geeignet zur Behandlung der Zuckerkrankheit charakterisieren.
In den Verbindungen der allgemeinen Formel I kann R1 die o-, m- oder p-Stellung einnehmen und beispielsweise folgende Bedeutungen haben: als niedere Alkylgruppe die Methyl-, Äthyl-, Propyl-, Isopropyl-, Butyl-, Isobutyl-, sek.Butyl-, tert.Butyl-, Pentyl-, Isopentyl- oder 2,2-Dimethyl-propylgruppe;
als niedere Alkoxygruppe die Methoxy-, Äthoxy-, Propoxy-, Isopropoxy-, Butoxy-, Isobutoxy-, sek.Butoxy-, tert.Butoxy-, Pentoxy-, Isopentoxy- sowie die 2,2-Dimethyl-propoxygruppe; als niedere Alkylthiogruppe die Methylthio-, Äthylthio-, Propylthio-, Isopropylthio-, die Butylthio-, Isobutylthio-, sek.Butylthio-, tert.Butylthio-, Pentylthio-, Isopentylthiosowie die 2,2-Dimethyl-propylthiogruppe und als niedere Alkanoylgruppe die Acetyl-, Propionyl-, 2-Methyl-propionyl-, Butyryl-, 2-Methyl-butyryl- sowie die 3-Methyl -butyrylgruppe.
Zur erfindungsgemässen Herstellung der Verbindungen der allgemeinen Formel I setzt man ein Isocyanatderivat der allgemeinen Formel II,
EMI1.2
in welcher R1, Wasserstoff, Halogen bis Atomnummer 35, die

EMI1.3
in welcher R1,, R2 oder R1, R. die unter Formel I bzw. II angegebene Bedeutung haben, mit dem 1,2,4,5 -Tetrahydro - 3H - 3 - benzazepin [vgl. P.
Ruggli et al.,
Helv. Chim. Acta 18, 1388 (1935)] oder mit einem Alkalimetallderivat dieser Verbindung um, hydrolysiert oder reduziert nötigenfalls das erhaltene Reaktionsprodukt zur Umwandlung der Gruppe R1, in die freie Ami nogruppe und führt gewünschtenfalls das erhaltene Reaktionsprodukt mit einer anorganischen oder organischen Base in ein Salz über.
Als reaktionsfähige funktionelle Derivate von Carbaminsäuren der allgemeinen Formel III kommen beispielsweise deren Halogenide, insbesondere die Chloride, und deren niedere Alkylester, insbesondere die Methyloder Äthylester, ferner die Phenylester in Betracht.
Weiter eignen sich Amide, Nitroamide, niedere Alkylamide, Dialkylamide, Diphenylamide, insbesondere N Methylamide, N,N-Dimethylamide, ferner N-Acylamide, wie z. B. Benzoylamide und 2-Oxoderivate von Polymethylenimiden, wie z. B. die 2-Oxoderivate der Pyrrolidinide, Piperidide, Hexamethylenimide oder der Octamethylenimide.
Als Beispiele von solchen funktionellen Derivaten von Carbaminsäuren der allgemeinen Formel III seien genannt: das N-Phenylsulfonyl-carbaminsäure-chlorid, der N-Phenylsulfonyl-carbaminsäure-methylester, -äthylester und -phenylester, der N-Phenylsulfonyl-harnstoff, der N-Nitro-N'-phenylsulfonyl-harnstoff, der N-Methyl-N' -phenylsulfonyl-harnstoff, der N,N-Dimethyl-N'-phenylsulfonyl-harnstoff, der N,N-Diphenyl-N' -phenylsulfonyl- harnstoff, der N-Benzoyl-N'-phenylsulfonyl-harnstoff,
das N-Phenylsulfonyl-2-oxo-pyrrolidin 1-carboxamid, das N -Phenylsulfonyl-2-oxo-piperidin- 1-carboxamid, N-Phenylsulfonyl-2-oxo-hexahydro- iH-azepin- 1 -carboxamid sowie das N-Phenylsulfonyl-2-oxo-octahydro- lH-azonin- 1 -carb- oxamid oder Derivate solcher Verbindungen, deren Rest R1, oder R,' R2 am Benzolkern mit den anschliessend an Formel I für den Rest R1 bzw. R1 R2 explizit aufgezählten Gruppen übereinstimmt.
Die Umsetzung erfolgt beispielsweise in der Kälte oder durch Erwärmen in einem inerten organischen Lösungsmittel. Geeignete inerte organische Lösungsmittel sind beispielsweise Kohlenwasserstoffe, wie Benzol, Toluol oder Xylol, ätherartige Flüssigkeiten, wie Diäthyl äther, Dioxan oder Tetrahydrofuran, chlorierte Kohlenwasserstoffe, wie Methylenchlorid, und niedere Ketone, wie Aceton oder Methyläthylketon.
Die Umsetzung eines Isocyanats, Carbaminsäureesters oder Harnstoffs kann auch in Abwesenheit von Lösungsoder Verdünnungsmitteln durchgeführt werden. Sie benötigt im allgemeinen auch kein Kondensationsmittel; gewünschtenfalls kann aber als solches Mittel z. B. ein Al kalialkoholat verwendet werden. Als weitere Kondensationsmittel können bei der Umsetzung eines Isocyanats tertiäre organische Basen Verwendung finden; Isocyanate können aber auch in Form eines Anlagerungsproduktes mit einer tertiären organischen Base eingesetzt werden.
Ein Carbaminsäurehalogenid wird erfindungsgemäss mit dem 1 ,2,4,5-Tetrahydro-3H-3-benzazepin, vorzugsweise in Gegenwart eines säurebindenden Mittels, umgesetzt. Als solches verwendet man anorganische Basen oder Salze, wie beispielsweise ein Alkalihydroxyd, -acetat, -hydrogencarbonat, -carbonat und -phosphat, wie Natrium-hydroxyd, -acetat, -hydrogencarbonat, -carbonat und -phosphat oder die entsprechenden Kaliumverbindungen. Ferner können auch Calcium-oxid, -carbonat sowie -phosphat und Magnesiumcarbonat eingesetzt werden. Anstelle von anorganischen Basen oder Salzen eignen sich auch organische Basen, wie z. B. Pyridin, Trimethyl- oder Triäthylamin, N,N-Diisopropylamin, Tri äthylamin oder Collidin. Diese können, im Überschuss zugefügt, auch als Lösungsmittel verwendet werden.
Anstelle von 1,2,4,5-Tetrahydro-3H-3-benzazepin kann zur erfindungsgemässen Umsetzung mit einem Carbaminsäurechlorid ein Alkalimetallderivat dieser Base, wie z. B. ein Natrium-, Kalium- oder Lithiumderivat, eingesetzt werden.
Die Umwandlung einer Gruppe R1, des Reaktionsproduktes in die freie Aminogruppe, welche das Reaktionsprodukt in eine Verbindung der allgemeinen Formel I überführt, wird je nach der Art der Gruppe R1 durch eine Hydrolyse, Reduktion oder reduktive Spaltung vorgenommen.
Durch Hydrolyse in die freie Aminogruppe überführbare Reste R1, sind beispielsweise Acylaminoreste, wie z. B. die Acetamidogruppe, oder Alkoxy- oder Phenoxycarbonylaminoreste, wie z. B. die Äthoxycarbonylaminooder Phenoxycarbonylaminogruppe. Weitere Beispiele sind substituierte Methylenaminoreste, wie z. B. die Benzylidenamino- oder die p-Dimethylamino-benzylidenaminogruppe. Die Hydrolyse zur Freisetzung der Aminogruppe kann z. B. in saurem Medium, wie durch Erhitzen in verdünnter methanolischer Salzsäure, oder, falls R1, einen Alkoxy- oder Phenoxycarbonylaminorest bedeutet, auch unter milden alkalischen Bedingungen, zum Beispiel mittels 1-n. bis 2-n. Natronlauge, bei Raumtemperatur erfolgen.
Ein Beispiel für einen durch Reduktion in die Aminogruppe überführbaren Rest R1, ist die Nitrogruppe und Beispiele für solche Reste, die durch reduktive Spaltung zur Aminogruppe führen, sind die Phenylazo- oder p-Dimethylamino-phenylazogruppen. Die Reduktion dieser Reste kann allgemein katalytisch, z. B. mittels Wasserstoff in Gegenwart von Raney-Nickel, Palladium- oder Platin-Kohle, in einem inerten Lösungsmittel, wie zum Beispiel Äthanol, erfolgen. Neben diesen kommen auch andere übliche Reduktionsverfahren in Betracht, beispielsweise die Reduktion von Nitrogruppen oder die reduktive Spaltung von Azogruppen mit Hilfe von Eisen in Essigsäure oder Salzsäure.
Die neuen Wirkstoffe oder die pharmazeutisch annehmbaren Salze derselben werden vorzugsweise peroral verabreicht. Zur Salzbildung können anorganische oder organische Basen, wie beispielsweise Alkali- oder Erdalkalihydroxyde, Carbonate oder Bicarbonate, Triäthanolamin, Cholin, N1-Dimethyl- oder N1-(h-Phenyläthyl)- -biguanid, verwendet werden. Die täglichen Dosen bewegen sich zwischen 100 und 2000 mg für erwachsene Patienten. Geeignete Doseneinheitsfonnen, wie Dragees, Tabletten, enthalten vorzugsweise 100 bis 500 mg eines erfindungsgemässen Wirkstoffes, und zwar 20 bis 80 ,go einer Verbindung der allgemeinen Formel I. Zu ihrer Herstellung kombiniert man den Wirkstoff z.
B. mit festen pulverförmigen Trägerstoffen, wie Lactose, Saccharose, Sorbit, Mannit; Stärken, wie Kartoffelstärke, Maisstärke oder Amylopektin, ferner Laminariapulver oder Citruspulpenpulver; Cellulosederivaten oder Gelatine, gegebenenfalls unter Zusatz von Gleitmitteln, wie Magnesiumoder Calciumstearat oder Polyäthylenglykolen von geeigneten Molekulargewichten zu Tabletten oder zu Dra gée-Kernen. Letztere überzieht man beispielsweise mit konzentrierten Zuckerlösungen, welche z. B. noch arabischen Gummi, Talk und/oder Titandioxid enthalten können, oder mit einem in leichtflüchtigen organischen Lösungsmitteln oder Lösungsmittelgemischen gelösten Lack. Diesen Überzügen können Farbstoffe zugefügt werden, z. B. zur Kennzeichnung verschiedener Wirkstoffdosen.
Die folgenden Vorschriften sollen die Herstellung von Tabletten und Dragees näher erläutern: a) 1000 g N-(p-Tolylsulfonyl)- 1 ,2,4,5-tetrahydro-3H- -3-benzazepin-3-carboxamid werden mit 550 g Lactose und 292 g Kartoffelstärke vermischt, die Mischung mit einer wässerigen Lösung von 8,0g Gelatine befeuchtet und durch ein Sieb granuliert.

As has now been found, the new compounds and their pharmaceutically acceptable salts have valuable pharmacological properties. Surprisingly, when administered orally or parenterally, they show hypoglycemic action, which characterizes them as being suitable for the treatment of diabetes.
In the compounds of general formula I, R1 can assume the o-, m- or p-position and have, for example, the following meanings: as the lower alkyl group, the methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec. Butyl, tert-butyl, pentyl, isopentyl or 2,2-dimethylpropyl group;

in which R1, hydrogen, halogen up to atomic number 35, the
Amino group or a lower alkyl, alkoxy,
Alkylthio or alkanoyl group, or a radical which can be converted into an amino group by hydrolysis, reduction or reductive cleavage, R2 denotes hydrogen or R1, R2 denotes the trimethylene or tetramethylene group, or a reactive functional derivative of a carbamic acid of the general formula III,
EMI1.3
in which R1, R2 or R1, R. have the meaning given under formula I or II, with the 1,2,4,5-tetrahydro-3H-3-benzazepine [cf. P.
Ruggli et al.,
Helv. Chim. Acta 18, 1388 (1935)] or with an alkali metal derivative of this compound, if necessary hydrolyzes or reduces the reaction product obtained to convert the group R1 into the free amino group and, if desired, converts the reaction product obtained into a salt with an inorganic or organic base .
Suitable reactive functional derivatives of carbamic acids of the general formula III are, for example, their halides, in particular the chlorides, and their lower alkyl esters, in particular the methyl or ethyl esters, and also the phenyl esters.
Amides, nitroamides, lower alkylamides, dialkylamides, diphenylamides, in particular N-methylamides, N, N-dimethylamides, and also N-acylamides, such as. B. benzoylamides and 2-oxo derivatives of polymethyleneimides, such as. B. the 2-oxo derivatives of pyrrolidinides, piperidides, hexamethyleneimides or octamethyleneimides.
Examples of such functional derivatives of carbamic acids of the general formula III are: N-phenylsulfonyl-carbamic acid chloride, N-phenylsulfonyl-carbamic acid methyl ester, ethyl ester and phenyl ester, N-phenylsulfonyl urea, N-nitro -N'-phenylsulfonyl-urea, the N-methyl-N'-phenylsulfonyl-urea, the N, N-dimethyl-N'-phenylsulfonyl-urea, the N, N-diphenyl-N'-phenylsulfonyl-urea, the N -Benzoyl-N'-phenylsulfonylurea,

The reaction takes place, for example, in the cold or by heating in an inert organic solvent. Suitable inert organic solvents are, for example, hydrocarbons such as benzene, toluene or xylene, ethereal liquids such as diethyl ether, dioxane or tetrahydrofuran, chlorinated hydrocarbons such as methylene chloride, and lower ketones such as acetone or methyl ethyl ketone.
The reaction of an isocyanate, carbamic acid ester or urea can also be carried out in the absence of solvents or diluents. In general, it also does not require a condensing agent; if desired, however, as such a means, for. B. be used an Al kalialkoholat. Tertiary organic bases can be used as further condensing agents in the reaction of an isocyanate; But isocyanates can also be used in the form of an addition product with a tertiary organic base.
According to the invention, a carbamic acid halide is reacted with the 1,2,4,5-tetrahydro-3H-3-benzazepine, preferably in the presence of an acid-binding agent. Inorganic bases or salts are used as such, such as an alkali hydroxide, acetate, hydrogen carbonate, carbonate and phosphate, such as sodium hydroxide, acetate, hydrogen carbonate, carbonate and phosphate or the corresponding potassium compounds. Calcium oxide, calcium carbonate and calcium phosphate and magnesium carbonate can also be used. Instead of inorganic bases or salts, organic bases are also suitable, such as. B. pyridine, trimethyl or triethylamine, N, N-diisopropylamine, triethylamine or collidine. These can, when added in excess, also be used as solvents.
Instead of 1,2,4,5-tetrahydro-3H-3-benzazepine, for the inventive reaction with a carbamic acid chloride, an alkali metal derivative of this base, such as. B. a sodium, potassium or lithium derivative can be used.
The conversion of a group R1 of the reaction product into the free amino group, which converts the reaction product into a compound of the general formula I, is carried out, depending on the nature of the group R1, by hydrolysis, reduction or reductive cleavage.
Radicals R1 which can be converted into the free amino group by hydrolysis are, for example, acylamino radicals, such as. B. the acetamido group, or alkoxy or phenoxycarbonylamino radicals, such as. B. the ethoxycarbonylamino or phenoxycarbonylamino group. Other examples are substituted methylene amino radicals, such as. B. the benzylideneamino or the p-dimethylamino-benzylideneamino group. The hydrolysis to release the amino group can, for. B. in an acidic medium, such as by heating in dilute methanolic hydrochloric acid, or, if R1 is an alkoxy or phenoxycarbonylamino radical, also under mild alkaline conditions, for example by means of 1-n. to 2-n. Caustic soda, at room temperature.
An example of a radical R1 which can be converted into the amino group by reduction is the nitro group and examples of such radicals which lead to the amino group by reductive cleavage are the phenylazo or p-dimethylaminophenylazo groups. The reduction of these residues can generally be catalytic, e.g. B. by means of hydrogen in the presence of Raney nickel, palladium or platinum carbon, in an inert solvent such as ethanol. In addition to these, other customary reduction processes can also be used, for example the reduction of nitro groups or the reductive cleavage of azo groups with the aid of iron in acetic acid or hydrochloric acid.
The new active ingredients or the pharmaceutically acceptable salts thereof are preferably administered orally. Inorganic or organic bases, such as, for example, alkali metal or alkaline earth metal hydroxides, carbonates or bicarbonates, triethanolamine, choline, N1-dimethyl- or N1- (h-phenylethyl) biguanide, can be used for salt formation. The daily doses range between 100 and 2000 mg for adult patients. Suitable dosage units, such as dragees, tablets, preferably contain 100 to 500 mg of an active ingredient according to the invention, namely 20 to 80, of a compound of the general formula I. For their preparation, the active ingredient is combined, for.
B. with solid powdery carriers such as lactose, sucrose, sorbitol, mannitol; Starches, such as potato starch, corn starch or amylopectin, also laminaria powder or citrus pulp powder; Cellulose derivatives or gelatin, optionally with the addition of lubricants, such as magnesium or calcium stearate or polyethylene glycols of suitable molecular weights, to tablets or to Dra gée cores. The latter is coated, for example, with concentrated sugar solutions, which z. B. can contain gum arabic, talc and / or titanium dioxide, or with a paint dissolved in volatile organic solvents or solvent mixtures. Dyes can be added to these coatings, e.g. B. to identify different drug doses.
