Verfahren zur Gewinnung therapeutisch wertvoller bakterizider Präparate.
EMI1.1
Stoffe hat noch nicht stattgefunden, obgleich die Zahl der in der Medizin verwendeter Silberpräparate eine sehr grosse ist.
Farbstoffe der Thioningruppe, speziell das Methylenblau (salzsaures Tetramethyithionm) finden vielseitige Verwendung als Heilmittel bei Infektionskrankheiten und Geschwülsten.
Es wurde nun die überraschende Entdeckung gemacht, dass die Farbstoffe der Thioningruppe mit Silbersalzen gut ausgeprägte Doppe1verbindungen liefern, welche ganz hervorragende antiseptische und bakterizide Wirkungen entfalten, in so geringen Mengen, dal keine Schädigung des menschlichen oder tierischen Organismus damit verbunden ist.
Die starke heilkräftige Wirkung der neuen Präparate beruht offenbar einerseits auf dem sehr hohen Gehalt an Silber (Methylenblausilbernitrat enthält über 20% Ag), das
EMI1.2
der Thioninfarbsto : ffe.
Dass diese, vom medizinischen Standpunkt aus, in der Theorie sehr wünschenswerte Kombination von Silber mit Thioninfarbstoffen praktisch durchführbar war, und dass das gewonnene Produkt auch die erwünschten Eigenschaften hatte, bedurfte der Feststellung durch umfangreiche Versuche.
Beispiel.
32 Teile reinstes Methylenblau werden in warmem Wasser gelöst und mit einer warmen Lösung von 14 g Silbernitrat in 50 Teilen Wasser vermischt.
Das ausgeschiedene Chlorsilber wird abfiltriert. Die klare Lösung wird zum Sieden erhitzt, wieder mit einer Lösung von 14 g Silbernitrat vermischt und bis auf etwa 1/20 ihres ursprünglichen Volumens eingedampft. Die Kristalle werden dann von der Lauge getrennt. in heissem Wasser gelöst, von einer geringen Menge nachträglich ausgeschiedenem Chlorsilber durch Filtration befreit und durch Einengen der Lösung wieder abgeschieden.
Man erhält bräunlich grüne Kristalle von Methylenblausilher mit 22'880/0 Ag, theoretisch 23'78% Ag.
Das Silbernitrat kann auch durch andere Silbersalze, z. B. die äquivalente Menge Silberzitrat, ersetzt werden.

Process for the production of therapeutically valuable bactericidal preparations.
EMI1.1
Substance has not yet taken place, although the number of silver preparations used in medicine is very large.
Dyes of the thionine group, especially methylene blue (hydrochloric acid tetramethylithione) are used in many ways as remedies for infectious diseases and tumors.
The surprising discovery has now been made that the dyes of the thionine group with silver salts provide well-defined double compounds which have excellent antiseptic and bactericidal effects, in such small quantities that they do not damage the human or animal organism.
The strong curative effect of the new preparations is apparently based on the one hand on the very high content of silver (methylene blue silver nitrate contains over 20% Ag), the
EMI1.2
the thionine dye: ffe.
That this combination of silver with thionine dyes, which is theoretically very desirable from a medical point of view, was feasible in practice, and that the product obtained also had the desired properties, had to be established through extensive experiments.
Example.
32 parts of the purest methylene blue are dissolved in warm water and mixed with a warm solution of 14 g of silver nitrate in 50 parts of water.
The precipitated silver chlorine is filtered off. The clear solution is heated to boiling, mixed again with a solution of 14 g of silver nitrate and evaporated to about 1/20 of its original volume. The crystals are then separated from the liquor. dissolved in hot water, freed from a small amount of subsequently precipitated silver chlorine by filtration and deposited again by concentrating the solution.
Brownish green crystals of methylene blue silver with 22,880 / 0 Ag, theoretically 23,78% Ag are obtained.
The silver nitrate can also be replaced by other silver salts, e.g. B. the equivalent amount of silver citrate to be replaced.
