Description
Verfahren zur Herstellung haltbarer wässeriger, therapeutisch verwendbarer Lösungen der Polyoxyalkylisoalloxazine Zusatz zum Patent 686 793 Das Patent 686 793 betrifft ein Verfahren, haltbare Lösungen der in Wasser nur schwer löslichen Polyoxyalkylisoalloxazine zu gewinnen durch die Verwendung von Mono-N-alkylderivaten der Amide niederer Fettsäuren als Lösungsmittel bzw. als Lösungsvermittler.Process for making durable aqueous, therapeutically useful Solutions of the polyoxyalkylisoalloxazines Addition to patent 686 793 The patent 686 793 relates to a method of preserving stable solutions that are only sparingly soluble in water Polyoxyalkylisoalloxazines can be obtained through the use of mono-N-alkyl derivatives of the amides of lower fatty acids as solvents or as solubilizers.
Bei der weiteren Bearbeitung hat sich gezeigt, daß man mit Vorteil auch die Salze von Phenol- bzw. Polyphenolsulfonsäuren als Lösungsvermittler verwenden kann. Schon bei verhältnismäßig geringen, z. B. 5 °/0 betragenden Konzentrationen der Salze von Phenol-bzw. Polyphenolsulfonsäuren lassen sich Lösungen erzielen, die im Vergleich zu wässerigen Lösungen einen mehrfachen Gehalt an Polyoxyalkylisoalloxazinen aufweisen. Die Lösungen können gleichzeitig mit anderen geeigneten Lösungsvermittlern, wie Fettsäurealkylamiden, Harnstoffen, Sarkosinanhydrid u. dgl., versetzt werden. Das beschriebene Verfahren eignet sich besonders zur Herstellung therapeutisch anwendbarer Lösungen des Lactoflavins. Further processing has shown that it is advantageous also use the salts of phenol or polyphenol sulfonic acids as solubilizers can. Even with relatively small, z. B. 5% concentrations the salts of phenol or. Polyphenolsulfonic acids can be used to achieve solutions which, compared to aqueous solutions, has a multiple content of polyoxyalkylisoalloxazines exhibit. The solutions can be used simultaneously with other suitable solubilizers, such as fatty acid alkylamides, ureas, sarcosine anhydride and the like. The method described is particularly suitable for producing therapeutically applicable ones Lactoflavin solutions.
Bei 20? löst beispielsweise eine 4%ige wässerige Lösung von phenolsulfonsaurein Natrium 0,05 °/0 Lactoflavin, eine 5 0/0ige wässerige Lösung von kresolsulfonsaurem Calcium o,o6 0!o Lactoflavin, eine 4°/0 wässerige Lösung von brenzkatechindisulfonsaurem Natrium 0,05010 Lactoflavin, eine 20 °/Oige wässerige Lösung des gleichen Salzes 0,4 01, Lactoflavin, eine 5 obige wässerige Lösung von phenolsulfonsaurem Natrium o,o6°/O 6, 7-Dimethyl-9-d-arabitylisoalloxazin, eine 50J0ige Lösung von brenzkatechindisulfonsaurem Natrium in Io°/Oiger wässeriger N°Methylacetamidlösung 0,08% Lactoflavin. At 20? dissolves, for example, a 4% aqueous solution of phenolsulfonic acid Sodium 0.05% lactoflavin, a 5% aqueous solution of cresol sulfonic acid Calcium o, o6 0! O Lactoflavin, a 4% aqueous solution of catechol disulphonic acid Sodium 0.05010 lactoflavin, a 20% aqueous solution of the same salt 0.4 01, lactoflavin, an aqueous solution of 5 above phenolsulfonic acid Sodium 0.06 / 0.67-Dimethyl-9-d-arabitylisoalloxazine, a 50% solution of Catechol disulphonic acid sodium in 10% aqueous N ° methylacetamide solution 0.08% lactoflavin.
PATENTANSPRÜCEE: I. Verfahren zur Herstellung haltbarer wässeriger, therapeutisch verwendbarer Lösungen der Polyoxyalkylisoalloxazine in Abänderung des Verfahrens nach Patent 686 793, dadurch gekennzeichnet, daß man phenol- bzw. polyphenolsulfonsaure Salze als Lösungsvermittler venvendet. PATENT CLAIMS: I. Process for the production of durable aqueous, therapeutically usable solutions of the polyoxyalkylisoalloxazines in modification of the process according to patent 686 793, characterized in that phenol or polyphenolsulfonic acid salts used as solubilizers.
