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.
