Description

Verfahren zur Gewinnung von den Glukoseabbau beschleunigenden Präparaten Es ist gefunden worden, daß alle tierischen Gewebe, besonders reichlich Gehirn, Milz und Retina, einen Stoff enthalten, der den Abbau der Glukose in der tierischen Zelle beschleunigt (vgl. K o p p e - S,e y 1 e r, Zeitschr. f. physiol. Chem., Bd. 193, 1930, Seite 238). Wir haben nun festgestellt, welche der Verfahren zur Herstellung von Organpräparaten zur Isolierung dieses - Stoffes besonders geeignet sind und in welcher Form und Reihenfolge sie angewendet werden müssen.Process for obtaining preparations that accelerate the breakdown of glucose It has been found that all animal tissues, especially the brain, spleen and retina in abundance, contain a substance that accelerates the breakdown of glucose in animal cells (cf.Koppe - S, ey 1 er, Zeitschr. f. Physiol. Chem., Vol. 193, 1930, page 238 ) . We have now established which of the processes for the production of organ preparations for the isolation of this substance are particularly suitable and in what form and order they must be used.

Man kann den wirksamen Stoff aus den mit Aceton und Äther getrockneten Geweben mit Wasser extrahieren. In den Extrakten ist er von zahlreichen hochmolekularen Substanzen, vor allem Eiweißkörpern, begleitet, welche seine. Wirksamkeit bedeutend herabsetzen und durch ihre Giftwirkung die Einführung des Präparats in den Organismus unmöglich machen. Es läßt sich von diesen Substanzen befreien, indem man ihn durch Alkoholzusatz niederschlägt und den in Wasser aufgenommenen Niederschlag durch Adsorption mit Tonerde oder Kaolin weiter reinigt. Die gewonnenen Lösungen sind für therapeutische Zwecke wertvoll. Der wirksame Stoff besitzt nun im Gegensatz zu den ungereinigten Extrakten genügende Haltbarkeit für die therapeutische Verwendung.One can get the active substance from the dried with acetone and ether Extract tissues with water. It is of numerous high molecular weight in the extracts Substances, especially protein bodies, accompanied which his. Significant effectiveness reduce and through their poisonous effect the introduction of the preparation into the organism to make impossible. It can be rid of these substances by passing it through Addition of alcohol precipitates and the precipitate absorbed in water by adsorption further cleans with clay or kaolin. The solutions obtained are for therapeutic Purposes valuable. The active substance now possesses in contrast to the unpurified Extracts have sufficient shelf life for therapeutic use.

Beispiele Tierisches Gewebe wird zerkleinert und durch mehrmaliges Behandeln mit Aceton und Äther getrocknet. Dann extrahiert man die Trockenpulver mit der 25fachen Menge '\@'asser zweckmäßig unter Zusatz von etwas Ammoniak und läßt einen halben Tag bei o° stehen. Man zentrifugiert und fällt die Lösung mit der 8fachen Menge Alkohol. Der Niederschlag, der die wirksame Substanz enthält, wird abzentrifugiert, mit Alkohol und Äther gewaschen und getrocknet.Examples Animal tissue is shredded and repeated several times Treat with acetone and ether dried. Then extract the dry powder with 25 times the amount of water, expediently with the addition of a little ammonia and lets stand at o ° for half a day. It is centrifuged and the solution is precipitated 8 times the amount of alcohol. The precipitate containing the active substance is centrifuged off, washed with alcohol and ether and dried.

Zur weiteren Reinigung wird der Niederschlag der Alkoholfällung mit dem 5ofachen seines Gewichts an Wasser extrahiert. Die Lösung versetzt man mit gerade so viel Tonerde oder Kaolin, daß die Eiweißkörper und die die Wirkung auf den Glukoseabbau hemmenden Substanzen entfernt werden, ohne daß mehr als wenige Prozente der wirksamen Substanz adsorbiert werden. Die dazu nötigen Mengen müssen von Fall zu Fall bestimmt werden. Man kann aber auch die Adsorption in der Weise ausführen, daß man die wirksame Substanz selbst mit der Hauptmenge der begleitenden hochmolekularen Stoffe an Tonerde oder Kaolin adsorbiert und aus dem Adsorbat die wirksame Substanz mit 2%iger Natriumbicarbonatlösung auswählend herauslöst.For further purification, the precipitate of the alcohol precipitation with extracted 5 times its weight in water. Add straight to the solution so much clay or kaolin that the protein and the effect on the glucose breakdown inhibiting substances are removed without more than a few percent of the effective Substance to be adsorbed. The quantities required for this must be determined on a case-by-case basis will. But you can also carry out the adsorption in such a way that you get the effective Substance itself with the majority of the accompanying high-molecular substances in clay or kaolin is adsorbed and the active substance from the adsorbate with 2% sodium bicarbonate solution selectively releases.
