Description

Verfahren zur Darstellung von Doppelverbindungen aus aliphatischen Amin-osäuren und anorganischen Alkalisalzen. Es ist bereits bekannt, daß man durch Einspritzung von sekundärem N atriumpbosphat die Verknöcherung des Callus bei Knochenfrakturen unterstützen kann. Diese Einspritzungen sind jedoch häufig mit unangenehmen Nebenwirkungen verbunden, die sich besonders durch Temperaturanstieg, Kopfschmerz und Erbrechen äußern. Wie nun beobachtet wurde, lassen sich diese Nebenerscheinungen vermeiden, wenn man an Stelle von Dinatriumphosphat zur Injektion Doppelverbindungen von Aminosäuren mit Alkaliphosphaten verwendet.Process for the preparation of double compounds from aliphatic Amino acids and inorganic alkali salts. It is already known that you can get through Injection of secondary sodium phosphate to ossify the callus in bone fractures can support. However, these injections are often associated with unpleasant side effects particularly associated with a rise in temperature, headache and vomiting to express. As has now been observed, these side effects can be avoided, if instead of disodium phosphate for injection double compounds of amino acids used with alkali phosphates.

Derartige Verbindungen waren bisher nicht bekannt. Man erhält sie, wie gefunden wurde, wenn man Aminosäuren oder Gemische von Aminosäuren in stöchiometrischen Verhältnissen auf Alkaliphosphate in gelöstem Zustand einwirken läßt. Die Doppelverbindungen kann man nach üblichen Methoden, z. B. durch Einengen ihrer Lösungen, durch Aussalzen oder durch Ausfällen mit Alkohol, zur Abscheidung bringen. Zur therapeutischen Verwendung ist es nicht notwendig, die Salze in trockenem Zustand darzustellen, sondern man kann ihre Lösungen in sterilisiertem Zu::ilnd unmittelbar zur Injektion gebrauchen. Beispiele. 1. Doppelverbindung aus Gty kokoll und sek. \ atriumphosphat.Such compounds were not previously known. You get them as was found when looking at amino acids or mixtures of amino acids in stoichiometric Can act conditions on alkali metal phosphates in the dissolved state. The double connections can be done by conventional methods such. B. by concentrating their solutions, by salting out or by precipitation with alcohol. For therapeutic use it is not necessary to represent the salts in a dry state, but one can use their solutions immediately for injection in a sterilized container. Examples. 1. Double connection from Gty kokoll and sec. \ atrium phosphate.

Zwecks Darstellung der festen kristallinischenDoppelverbindung vonGlykokoll mit Dinatriumphosphat «-erden drei Raumteile einer cnolaren wässerigen Dinatriumphosphatlösung (in 1 1 Wasser enthaltend 358,24 g Dinatriumphosphat) mit siebenRauinteilen einer molaren wässerigen Glykokollösung (in 1 1 Wasser enthaltend 75,1 g Glykokoll) bei 2o° versetzt und vier Raumteile 96prozentiger Alkohol zugegeben, worauf die Kristallausscheidung allmählich einsetzt. Die Doppelverbindung ist leicht löslich in Wasser. Seine Lösung kann durch Kochen sterilisiert werden; eine .n-Lösung besitzt eine Wasserstoffionenkonzentration pH= 8,o-8,2.For the purpose of representing the solid crystalline double compound of glycoll with disodium phosphate "earths, three parts by volume of a cnolar aqueous disodium phosphate solution (in 1 l of water containing 358.24 g of disodium phosphate) with seven parts of a molar aqueous glycocollolution (in 1 l of water containing 75.1 g of glycocolla) at 20 ° and four parts by volume of 96% alcohol are added, whereupon the precipitation of crystals gradually begins. The double compound is easily soluble in water. Its solution can be sterilized by boiling; an .n solution has a hydrogen ion concentration pH = 8.0 -8.2.

2. Doppelverbindung aus Leucin und sek. Natriumphosphat. 22,9 g Leucin und 26,8 g Dinatriumphosphat werden in 80o ccm Wasser gelöst und 320 ccm 96prozentiger Alkohol zugefügt. Die Doppelverbindung scheidet sich allmählich ab. Sie wird abgesaugt und getrocknet. In Wasser ist das Produkt leicht löslich.2. Double compound of leucine and sec. Sodium phosphate. 22.9 g of leucine and 26.8 g of disodium phosphate are dissolved in 80o cc of water and 320 cc of 96 percent alcohol are added. The double compound gradually separates out. It is vacuumed and dried. The product is easily soluble in water.

3. Doppelverbindung aus Alanin und sek. Natriumphosphat. Eine wässerige Lösung von 10,74g Dinatriumphosphat und 6,23 g Alanin in looccm Wasser wird mit 4o ccm 96prozentigen Alkohols -versetzt. In Eis gestellt beginnt bald die Kristallisation der Doppelverbindung. Sie wird abgesaugt und getrocknet. In Wasser ist sie leicht löslich. q.. Doppelverbindung aus Glykokollund sek. Kaliumphosphat.3. Double compound from alanine and sec. Sodium phosphate. 40 cc of 96 percent alcohol are added to an aqueous solution of 10.74 g of disodium phosphate and 6.23 g of alanine in 100 cm of water. When placed in ice, the double compound soon begins to crystallize. It is vacuumed and dried. It is easily soluble in water. q .. double compound from glycocolland sec. Potassium phosphate.

10,59 sek. Kaliumphosphat und 10,59 Glykokoll werden in zoo ccm Wasser gelöst. Die Lösung wird bis zur beginnenden .Kristallisation auf dem Wasserbad eingeengt und nach dem Erkalten die ausgeschiedene Doppelverbindung abgesaugt. Sie ist in Wasser leicht löslich. 5. Doppelverbindung aus Glykokoll und tert. Natriumphosphat. Eine Lösung von 1o,3 g tert. Natriumphosphat und 2,3 g Glykokoll in 4o ccm Wasser wird mit dem doppelten Volumen 96prozentigen Alkohols versetzt. Aus der Lösung scheidet sich bald die Doppelverbindung ab. Sie wird abgesaugt und getrocknet. In Wasser löst sie sich leicht mit schwach alkalischer Reaktion. 10.59 sec. Potassium phosphate and 10.59 glycocolla are dissolved in zoo cc of water. The solution is concentrated on the water bath until crystallization begins and, after cooling, the double compound which has separated out is suctioned off. It is easily soluble in water. 5. Double compound from glycocolla and tert. Sodium phosphate. A solution of 1o, 3 g tert. Sodium phosphate and 2.3 g of glycocolla in 40 cc of water are mixed with twice the volume of 96 percent alcohol. The double compound soon separates out of the solution. It is vacuumed and dried. It easily dissolves in water with a weakly alkaline reaction.
