Description
Verfahren zur Herstellung einer komplexen Gold-Stärke-Pepton-Verbindang.
Es wurde gefunden, dass man zu komplexen, wasserlöslichen Verbindungen von Stärke und Goldsalzen mit Eiweissabbauprodukten gelangen kann, die die üblichen Goldionen-Reaktionen nicht mehr zeigen, indem man Goldpepton oder Goldalbumose mit Stärke umsetzt. Die Umsetzung erfolgt am besten in der Wärme und in saurem, wässrigen Medium, zu dessen Herstellung die saure Hydrolysenreaktion der Goldsalze genügt. Sehr wahrscheinlich treten die Anionen der verwendeten Goldverbindungen in den erzeugten Komplexverbindungen nicht auf.
Wegen der kolloidalen Natur der Reaktionsprodukte ist der strikte Beweis sehr schwer zu führen, doch kann aus der Menge der entstehenden freien Säuren, die aus den Anionen der Goldsalze stammen, geschlossen werden, dass die Anionen zur Hauptsache an der Kondensation unbeteiligt sind. Die wasserlöslichen Reaktionsprodukte können durch geeignete Fällungsmittel, wie zum Beispiel Pikrinsäure, abgeschieden werden.
Die Herstellung von Verbindungen von Pepton oder andern wasserlöslichen Eiweissabbauprodukten mit Goldsalzen ist bekannt.
Diese Verbindungen sind aber in Wasser unlöslich. Durch Behandlung mit überschüssigen Eiweissstoffen können sie zwar in lösliche Form gebracht werden. Sie enthalten aber darin das Gold nicht in chemisch gebundener, sondern in freier kolloidaler Form.
Ihre wässrigen Lösungen sind daher tiefrot oder violett gefärbt und flocken nach kurzer Zeit aus. Dagegen werden nach vorliegendem Verfahren, wie sich zeigte, echte komplexe Verbindungen erhalten. Ihre gelblich gefärbten, wässrigen Lösungen sind, wie Versuche ergaben, unbeschränkt haltbar. Dies ist in praktischer Hinsicht, zum Beispiel zur Herstellung von Injektionslösungen, von entscheidender Bedeutung. Die Präparate zeichnen sich durch besondere therapeutische Eigenschaften aus.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer komplexen Gold-Stärke-Pepton-Verbindung, welches dadurch gekennzeichnet ist, dass man ein Goldsalz, Pepton und Stärke in saurem, wässrigem Medium miteinander umsetzt und die Reaktionslösung klarfiltriert.
Das Reaktionsprodukt gibt eine gelbliche Lösung von eigenartig süsslichem Geruch, die sich zu einem gelblich braunen, in Wasser wieder klar löslichen Pulver einengen lässt.
Die neue komplexe Gold-Pepton-Stärke-Verbindung besitzt wertvolle therapeutische Eigenschaften.
Beispiel :
10 Gewichtsteile Pepton werden in 100 Gewichtsteilen Wasser gelöst, wenn nötig von Ungelöstem abfiltriert und mit überschüssiger, 10 % iger Goldchloridlösung in der I(älte versetzt. Das ausgefällte, wasserunlösliche Produkt wird in eine kochende Lösung von 1 Gewichtsteil einer beliebigen Stärkesorte in 1000 Gewichtsteilen Wasser eingetragen, wobei es sehr bald in Lösung geht. Diese Lösung wird weiter erhitzt, bis sich der Überschuss an eingebrachtem Gold abgeschieden hat, blank filtriert und auf dem Wasserbad langsam bis zur Trockne eingedampft. Das Produkt ist ein gelblichbraunes Pulver von eigentümlichem, süsslichem Geruch, welches sich im Gegensatz zu entsprechenden Konzentrationen von Pepton oder Stärke in Wasser unverzüglich und klar löst.
Process for the production of a complex gold-starch-peptone compound.
It has been found that complex, water-soluble compounds of starch and gold salts with protein degradation products can be obtained that no longer show the usual gold ion reactions by converting gold peptone or gold albumose with starch. The reaction is best carried out in the heat and in an acidic, aqueous medium, for the production of which the acidic hydrolysis reaction of the gold salts is sufficient. It is very likely that the anions of the gold compounds used do not occur in the complex compounds produced.
Because of the colloidal nature of the reaction products, strict evidence is very difficult to provide, but from the amount of free acids formed, which come from the anions of the gold salts, it can be concluded that the anions are mainly not involved in the condensation. The water-soluble reaction products can be deposited by suitable precipitating agents, such as picric acid.
The production of compounds of peptone or other water-soluble protein degradation products with gold salts is known.
However, these compounds are insoluble in water. By treating them with excess proteins, they can be converted into soluble form. However, they do not contain the gold in chemically bound, but in free colloidal form.
Their aqueous solutions are therefore deep red or purple in color and flocculate after a short time. In contrast, as has been shown, true complex compounds are obtained according to the present process. Experiments have shown that their yellowish-colored, aqueous solutions can be kept indefinitely. This is of crucial importance in practical terms, for example for the preparation of injection solutions. The preparations are characterized by special therapeutic properties.
The subject of the present patent is a process for the production of a complex gold-starch-peptone compound, which is characterized in that a gold salt, peptone and starch are reacted with one another in an acidic, aqueous medium and the reaction solution is filtered clear.
The reaction product gives a yellowish solution with a peculiarly sweet odor, which can be concentrated to a yellowish brown powder that is again clearly soluble in water.
The new complex gold-peptone-starch compound has valuable therapeutic properties.
Example:
10 parts by weight of peptone are dissolved in 100 parts by weight of water, if necessary filtered off from undissolved material and mixed with excess 10% gold chloride solution in the cold. The precipitated, water-insoluble product is dissolved in a boiling solution of 1 part by weight of any type of starch in 1000 parts by weight of water This solution is heated further until the excess gold has been deposited, filtered until it is clear and slowly evaporated to dryness on a water bath. The product is a yellowish-brown powder with a peculiar, sweet odor, which in contrast to corresponding concentrations of peptone or starch in water dissolves immediately and clearly.
