Description
Verfahren zur Darstellung niehtfloehender Lösungen eiweisshaltiger Heilmittel. Bekanntlich zeigen eiweisshaltige Lösun gen die Eigenschaft, dass sie nicht dauernd klar bleiben, sondern zur Flockenbildung neigen, was auf Denaturierung des Eiweisses beruht. Dieser Umstand macht sich beson ders bei therapeutischen Präparaten störend bemerkbar.
Es wurde nun gefunden, dass man die Flockung von eiweisshaltigen Lösungen von Heilmitteln aufheben oder weitgehend ver hindern kann, indem man das eiweisshaltige Heilmittel mit höhermolekularen Eiweissab- bauprodukten, zuni Beispiel Säuren wie Prot- albinsäure, Lysalbinsäure usw. zusammen bringt. Insbesondere sind die Salze dieser Ei weissabbauprodukte, besonders die Alkali salze, wie zum Beispiel die Natrium- oder Kaliumsalze, für das Verfahren geeignet.
Man führt das Verfahren zweckmässig so aus, dass man die erwähnten Stoffe den Lö sungen der eiweisshaltigen Heilmittel zugibt. Mit gleichem Erfolge kann jedoch auch der die Flockung verhindernde Stoff einem festen eiweisshaltigen Heilmittel zugegeben und dann das so erhaltene Produkt in Lö sung gebracht werden.
Bei dem Verfahren spielen sich insofern chemische Prozesse ab, als das höhermoleku- lare Eiweissabbauprodukt, beispielsweise das Albuminat, mit den durch örtliche Einwir kung an der Oberfläche der Lösung oder an der Glaswand des Gefässes sich denaturieren den Eiweissteilchen in Reaktion tritt, unter Bildung eines nicht ausflockenden Kom plexes.
Durch diese Verhinderung der weiter um sich greifenden Denaturierung tritt, wie Versuche ergaben, eine weitere chemische Reaktion ein, die darin besteht, dass die Ver schiebung der Wasserstoffionenkonzentration der Lösung in das alkalische Gebiet verhin dert wird, die sonst beim Koagulieren einer beliebigen Eiweisslösung stets eintritt (siehe unter anderem Cohnheim, Chemie der Ei weisskörper, III, S. 15G). Als eiweisshaltige Heilmittel kommen beispielsweise die Absonderungsprodukte von Drüsen in Frage, ferner Serumeiweissstoffe oder Eiweisskörper aus Krebsgeweben.
Als höhenmolekulare Abbauprodukte können ver wendet werden Spaltprodukte, erhalten durch alkalischen Abbau des Eiweisses, ferner Peil- tone, erhalten durch enzymatischen Abbau, zum Beispiel durch Pepsinabbau.
Beispiele: 1. Eine . 1 % ige Thyreoglobulinlösung wird nach dem Zusatz eines Sterilisi.erungs- mittels mit etwa 1 % protalbinsaurem Na trium unter Umrühren versetzt. Die Lösung zeigt nach dem Filtrieren keine Flockenbil- dung mehr.
2. Eine fraktionierte Thyreoglobulinlösung wird auf die gewünschte Konzentration einge stellt und mit soviel protalbinsaurem Na trium versetzt, dass die Lösung etwa 1 /00 davon enthält. Die Lösung wird nunmehr mit Trikresol sterilisiert und durch Seitz- filter geklärt.
3. Trockenpulver von Insulin wird nach dem Ergebnis der Standardisierung mit Al kali- bezw. Natriumalbuminat vermischt und die Substanz allmählich in der berechne ten Menge sauren Wassers aufgelöst, so dass eine an Alkalialbuminat etwa 1 /ooige Lö sung entsteht. Nach dem Filtrieren erhält man eine beständige, keine Flocken bildende Lösung.
Process for the preparation of non-escaping solutions of proteinaceous remedies. It is known that solutions containing protein show the property that they do not remain clear all the time, but tend to form flakes, which is based on denaturation of the protein. This fact is particularly noticeable in the case of therapeutic preparations.
It has now been found that the flocculation of protein-containing solutions of medicinal products can be eliminated or largely prevented by combining the protein-containing medicinal product with higher molecular weight protein degradation products, for example acids such as protalbic acid, lysalbic acid, etc. In particular, the salts of these protein degradation products, especially the alkali salts, such as the sodium or potassium salts, are suitable for the process.
The process is expediently carried out in such a way that the substances mentioned are added to the solutions of the protein-containing remedies. With the same success, however, the substance preventing flocculation can also be added to a solid protein-containing remedy and then the product thus obtained can be dissolved.
In the process, chemical processes take place insofar as the higher molecular protein degradation product, for example the albuminate, with which the protein particles are denatured due to local effects on the surface of the solution or on the glass wall of the vessel, does not react to form one flocculating complex.
As experiments have shown, this prevention of the further spreading denaturation occurs, which consists in preventing the shift in the hydrogen ion concentration of the solution into the alkaline area, which otherwise always occurs when any protein solution is coagulated (see, inter alia, Cohnheim, Chemie der Eiweißkörper, III, p. 15G). As protein-containing remedies, for example, the secretion products of glands come into question, as well as serum proteins or protein bodies from cancerous tissues.
Cleavage products obtained by alkaline breakdown of the protein, and also bearing clays, obtained by enzymatic breakdown, for example by pepsin breakdown, can be used as high molecular weight breakdown products.
Examples: 1. One. After adding a sterilizing agent, 1% thyroglobulin solution is mixed with about 1% sodium protalbinate while stirring. After filtration, the solution no longer shows any formation of flakes.
2. A fractionated thyroglobulin solution is adjusted to the desired concentration and so much protalbinate sodium is added that the solution contains about 1/00 of it. The solution is now sterilized with tricresol and clarified through a Seitz filter.
3. Dry powder of insulin is based on the result of the standardization with Al kali- or. Sodium albuminate mixed and the substance gradually dissolved in the calculated amount of acidic water, so that a solution of about 1 / o in alkali albuminate is formed. After filtration, a stable, non-flaky solution is obtained.
