Description
Verfahren zur Gewinnung eines haltbaren, wasserlöslichen Trockenpräparates des Kreislaufhormons aus Harn Es sind bereits Verfahren zur - Gewinnung eines Stoffes aus dem Harn bekannt, der eine Senkung des Blutdruckes bei gleichzeitig vermehrter Durchblutung von Lunge, Gehirn und Muskulatur bewirkt und der als Kreislaufhormon bezeichnet wird. Aus den nach diesen Verfahren angereicherten Hormonlösungen konnte bisher ein Trockenpräparat nur ..erhalten werden durch Eindampfen im Vakuum bei niedrigerer Temperatur. Da reinere Kreislaufhormonlösungen bereits bei 6o° in wenigen Minuten ihre physiologische Wirksamkeit völlig einbüßen, durfte die Temperatur des Bades q.0° nicht übersteigen. Diese Methode ist kostspielig und technisch schwer durchführbar, da die Lösungen außerordentlich stark schäumen. Das auf diese Weise erhaltene Pulver ist nicht vollständig wasserlöslich.Process for obtaining a durable, water-soluble dry preparation of the circulatory hormone from urine There are already processes for - extraction of a substance known from urine, which lowers blood pressure while increasing it It causes blood flow in the lungs, brain and muscles and acts as a circulatory hormone referred to as. From the hormone solutions enriched according to this procedure so far a dry preparation only .. can be obtained by evaporation in a vacuum lower temperature. Since purer circulatory hormone solutions already at 60 ° in a few Minutes completely lose their physiological effectiveness, the temperature of the Do not exceed q.0 ° in the bath. This method is expensive and technically difficult feasible, since the solutions foam extremely strongly. That way powder obtained is not completely soluble in water.
Es- wurde nun gefunden, daß, man mit Ausbeuten von 85 bis noo % auf technisch einfache Weise Trockenpulver des Kreislaufhormons erhalten kann, wenn man die Lösungen bei niedriger Temperatur mit Aceton fällt, den Niederschlag sofort abtrennt und durch Waschen mit Äther trocknet. Dieses Pulver ist leicht und vollständig in Wasser löslich und behält seine volle physiologische Wirksamkeit selbst nach monatelangem Aufbewahren im Brutschrank. Die Fällung ist auch durchführbar in salz- und eiweißfreien Lösungen. Das erhaltene Pulver kann auch in wäßrige Lösung gebracht und dann auf bekannte Weise durch Adsorption an Uranylacetat, Benzaesäure, Tonerde, Kaolin u. dgl. weiter gereinigt werden.It has now been found that, with yields of 85 to noo% technically simple way can get dry powder of the circulatory hormone, if if the solutions are precipitated with acetone at a low temperature, the precipitate immediately separated and dried by washing with ether. This powder is light and complete soluble in water and retains its full physiological effectiveness itself months of storage in the incubator. The precipitation can also be carried out in salt and protein-free solutions. The powder obtained can also be brought into an aqueous solution and then in a known manner by adsorption on uranyl acetate, benzaic acid, clay, Kaolin and the like can be further purified.
Es sind bereits Fällungen mit Aceton beschrieben worden zur Gewinnung
von kreislaufhormonhaltigen Präparaten aus Pankreas und Blut. Mit diesen Methoden
ist das vorlijegende Verfahren nicht identisch. Denn der Acetonzusatz zum Blut dient
der Einleitung eines fermentativen Prozesses, der die Spaltung der physiologisch
unwirksamen Verbindung Kreislaufhormon-Inaktivator herbeiführt, der also das aktive
Hormon selbst erst freilegen soll. Die Acetonfällung der wäßrigen Auszüge getrockneter
Pankreasdrüsen bewirkt die Abtrennung des Kreislaufhormons vom blutzuckersenkenden
Hormon der Pankreasdrüse; dabei handelt es sich um die Ausfällung eines Eiweißniederschlages,
der das Kreislaufhormon adsorptiv gebunden enthält. Gegenstand der vorliegenden
Erfindung ist dagegen eine Fällungsmethode, die vor allem auf eiweißfreie Lösungen
angewandt wird. Währendbeider Acetonfällung aus Blut das Keton mehrere Stunden bei
Zimmer oder Bruttemperatur auf das Substrat einwirken muß, um die gewünschte
Gleichzeitig bedeutet das hier beschriebene Verfahren eine Reinigung, . da durch die Acetonfällung bis zu 5o % der unwirksamen Begleitstoffe abgetrennt werden.At the same time, the process described here means cleaning, . because up to 5o% of the ineffective accompanying substances are separated off by the acetone precipitation will.
Die aus Blut bzw. Pankreas mit Aceton gewonnenen Präparate verlieren schon nach kurzer Zeit ihre pharmakologische Wirksamkeit (Frey, Kraut und Werte, Zeitschrift für physiol. Chemie,- 189, 3 und q., Seite 98, Zeile 25, und Seite 104, Zeile i), während die nach obigem Verfahren gewonnenen Präparate haltbar sind.The preparations obtained from blood or pancreas with acetone lose their pharmacological effectiveness after a short time (Frey, Kraut undwerte, Zeitschrift für physiol. Chemie, - 189, 3 and q., Page 98, line 25, and page 104, line i), while the preparations obtained by the above process are stable.
Beispiel 8 1 = 8o ooo Einheiten salz- und eiweißfreie wäßrige Kreislaufhormonlösung vom Reinheitsgrad 0,3 mg pro Einheit werden auf q.° gekühlt und mit 16 1 Aceton von ¢° versetzt, wodurch eine milchige Trübung entsteh. Auf Zusatz einer geringen Menge Kochsalz (etwa r/2 g) fällt ein weißer, flockiger Niederschlag aus, der sofort mit der Sharpleszentrifuge abgetrennt wird. Das Zentrifugat wird mit trockenem Acetonäther angerührt, abgesaugt und mit trockenem Äther nachgewaschen. Nach Trocknung an der Luft wird fein pulverisiert und im Vakuum vollständig getrocknet. Das hellgraue Pulver löst sieh leicht und klar in Wasser. Eine Kreislaufhormoneinheit ist gebunden an 0,17 mg organischer Substanz. Die biologische Ausbeute beträgt 9o %.EXAMPLE 8 1 = 80,000 units of salt-free and protein-free aqueous circulatory hormone solution with a degree of purity of 0.3 mg per unit are cooled to q ° and mixed with 16 l of acetone at ¢ °, resulting in a milky cloudiness. When a small amount of common salt (approx. R / 2 g) is added, a white, flaky precipitate forms, which is immediately separated off with the Sharples centrifuge. The centrifugate is mixed with dry acetone ether, filtered off with suction and washed with dry ether. After drying in air, it is finely pulverized and completely dried in vacuo. The light gray powder dissolves easily and clearly in water. One circulatory hormone unit is bound to 0.17 mg of organic matter. The biological yield is 90%.
