Description

  

      Verfahren    zur     Herstellung        einer        zur    Injektion     geeigneten    Lösung     eines        Derivates     eines     Heilstoffes.       Das     p-Amino-benzolsulfonamid    und seine  als Heilmittel verwendeten Derivate sind  zumeist in Wasser wenig löslich und des  halb für Injektionen ungeeignet.

   Es wurde  nun gefunden, dass sich     ,solche        Sulfonamide.,     die ausser an der freien     p-ständigen        Amino-          gruppe    noch an einer     anderweitigen    Stelle des  Moleküls ein leicht     substituierbares    Wasser  stoffatom aufweisen, in     einer    wässerigen Lö  sung einer     Hexose,    z. B. Glukose,     Galaktose,          Mannose,    und eines     Bisülfites,    z. B.

   Natrium-,  Kalium-,     Ammoniumbisulfit,    oder in einer  wässerigen Lösung eines     ä-oxy-alkylsulfin-          sauren    Salzes (Alkali- oder     Ammoniumsalz)     zu einer mindestens nahezu neutralen, für       Injektionen    verwendbaren Lösung auflösen  lassen. Injektionslösungen von     besondershoher     Konzentration können mit Hilfe der     Bisulfite          bezw.        a-Oxy-alkylsulfinate    von Aminen, z. B.  von     Diäthylamin,        Diäthanolamin,        Morpholin,     erhalten werden.  



  Gegenstand der     Erfindung    ist ein Verfah  ren zur Herstellung einer zur Injektion geeig  neten Lösung     eines    neuen Derivates des be  kannten Heilstoffes     p-Amino-benzolsulfon-          amid,    welches dadurch gekennzeichnet ist,

    dass man 1     Mol        p-Amino-benzolsulfonamid     und je     mindestens    2 Mole Glukose und Na  triumbisulfit in wässerigem Medium aufein  ander einwirken lässt Die letzteren beiden  Stoffe verbinden sich bekanntlich leicht schon  bei     gewöhnlicher        Temperatur    zu     glukose-          sulfonsaurem        Natrium,    und dieses setzt sieh         mit    dem p -     Amino    -     benzolsulfonamid    zu  p -     amino    -     benzols.ulf        onamid    -<B>N,

  97-</B>     diglukose-          sulfonsaurem        Natrium    um. Auf 1 Molekül       p-Amino-benzolsulfonamid    werden vorteilhaft  2,5 Moleküle Glukose und 2,2 Moleküle       Natriumbisulfit    verwendet. Die     farb-    und  geruchlose Lösung des     p-amino-benzolsulfon-          amid    -     N,N'    -     diglukosesulf        onsauren    Natriums  ist haltbar, lässt sich in hoher     Konzentration     darstellen und ohne     Ausscheidungen    genau  neutralisieren, verdünnen und sterilisieren.  



  Das     erfindungsgemässe    Verfahren kann       beispielsweise    folgendermassen ausgeführt  werden:  In eine Suspension von 17,2 g     p-Amino-          benzolsulfonamid    in 100 cm'     Wasser    wird  ein     Gemisch    von 44,6 g Glukose und 22,8 g       Natriumbisulfit    eingetragen und das Ganze       bis    zur vollständigen Auflösung des     p-Amino-          benzolsulfonamids:

      unter Rühren auf dem       Wasserbade    erhitzt, dann mit     Natriumhydro-          xyd    genau neutralisiert und mit     destilliertem          Wasser    auf 172 cm? verdünnt.  



  Die     Lösung    der neuen     Verbindung    ist wie  das     p-Amino-benzolsulfonamid    gegen     Strepto-          und        Pneumokokkeninfektionen    wirksam, hat  aber dem     p-Amino-benzolsulfonamid    gegen  über den     Vorteil,,    dass sich an der Injektions  stelle keine Gewebsnekrosen bilden.



      Process for the preparation of a solution of a derivative of a medicinal substance suitable for injection. The p-amino-benzenesulfonamide and its derivatives used as medicinal products are mostly sparingly soluble in water and therefore unsuitable for injections.

   It has now been found that such sulfonamides. Which, in addition to the free p-position amino group, have an easily substitutable hydrogen atom at another point on the molecule, in an aqueous solution of a hexose, eg. B. glucose, galactose, mannose, and a bisulfite, e.g. B.

   Dissolve sodium, potassium, ammonium bisulfite, or in an aqueous solution of an a-oxy-alkylsulfinic acid salt (alkali or ammonium salt) to form an at least almost neutral solution that can be used for injections. Injection solutions of particularly high concentration can with the help of bisulfites respectively. α-oxy-alkyl sulfinates of amines, e.g. B. of diethylamine, diethanolamine, morpholine can be obtained.



  The invention relates to a process for the production of a suitable solution for injection of a new derivative of the known medicinal substance p-amino-benzenesulfonamide, which is characterized by

    that 1 mole of p-amino-benzenesulfonamide and at least 2 moles of glucose and sodium bisulfite each are allowed to act on each other in an aqueous medium - Amino - benzenesulfonamide to p - amino - benzenesulfonamide - <B> N,

  97- </B> sodium diglucose sulfonic acid. 2.5 molecules of glucose and 2.2 molecules of sodium bisulfite are advantageously used for 1 molecule of p-amino-benzenesulfonamide. The colorless and odorless solution of p-amino-benzenesulfonamide - N, N '- diglukosesulfonsauren sodium is stable, can be prepared in high concentration and precisely neutralized, diluted and sterilized without excretions.



  The process according to the invention can be carried out, for example, as follows: A mixture of 44.6 g glucose and 22.8 g sodium bisulfite is introduced into a suspension of 17.2 g p-aminobenzenesulfonamide in 100 cm 'water and the whole is added until it is completely dissolved of p-amino benzenesulfonamide:

      heated with stirring on the water bath, then exactly neutralized with sodium hydroxide and adjusted to 172 cm? with distilled water. diluted.



  Like p-amino-benzenesulfonamide, the solution of the new compound is effective against streptococcal and pneumococcal infections, but has the advantage over p-amino-benzenesulfonamide that no tissue necrosis is formed at the injection site.
