Österreichische PATENTSCHRIFT Nu-"15495.
FARBENFABRIKEN VORM, FRIEDR. BAYER & Co. IN ELBERFELD. Verfahren zur Darstellung von Formaldehydverbindungen der Nucleinsäuren und von deren phosphorsäurehaltigen Abbauprodukten.
Es wurde gefunden, dass die Nukleinsäuren (sowohl animalischen als auch vegetabilischen Ursprungs) sowie deren phosphorsäurehaltige Abbauprodukte, wie z. B. die Nudeothyminsäure und die Thyminsäure, die Eigenschaft besitzen, sich direkt mit Formaldehyd zu verbinden. Die so erhältlichen neuen Körper bilden gelblichweisse bis braune, unzersetzt haltbare Pulver, deren Alkalisalze in Wasser leicht löslich sind. I) ie wässerigen Lösungen der Salze sind in der Kalte ebenfalls beständig, dieselben spalten jedoch beim Erwärmen auf dem Wasserbade Formaldehyd ab. DAdurch, dass der Formaldehyd in diesen Präparaten relativ locker gebunden ist, kann derselbe im Organismus leicht seine Wirkung entfalten, deshalb haben diese neuen Verbindungen sehr wertvolle therapeutische Eigenschaften.
Das neue Verfahren sei durch folgende Beispiele erläutert :
Beispiel 1. 50 g nuc1einsaures Natrium beliebigen Ursprungs (z. H. aus herrings-

Austrian PATENT NUMBER "15495.
FARBENFABRIKEN VORM, FRIEDR. BAYER & Co. IN ELBERFELD. Process for the preparation of formaldehyde compounds of nucleic acids and their phosphoric acid-containing degradation products.
It was found that the nucleic acids (both animal and vegetable origin) and their phosphoric acid-containing degradation products, such as. B. Nudeothymic acid and thymic acid, have the property of combining directly with formaldehyde. The new bodies thus obtainable form yellowish-white to brown, undecomposed stable powders, the alkali salts of which are easily soluble in water. I) The aqueous solutions of the salts are also stable in the cold, but they split off formaldehyde when heated on the water bath. Because the formaldehyde is relatively loosely bound in these preparations, it can easily develop its effect in the body, which is why these new compounds have very valuable therapeutic properties.
The new method is illustrated by the following examples:
Example 1. 50 g of sodium nucleic acid of any origin (e.g. from herrings-
