Description
Verfahren zur Herstellung eines antira.cvitisch wirkenden Präparates. Es ist bekannt, dass man dem Chole sterin, Phytosterin, Sitosterin und Ergosterin durch Bestrahlung mit ultraviolettem Licht eine hohe Wirksamkeit gegen Rachitis ver leihen kann (siehe zum Beispiel Chemisches Centralblatt 1926, Il. Band, Seite 289,4, 0. Rosenheim und Th. A. Webster).
Dabei tritt unter den in dieser Literatur stelle angegebenen Reaktionsbedingungen bei keinem dieser Produkte eine chemisch nach -eisbare Umwandlung auf, auch nicht bei dem Ergosterin, wie eine Nacharbeitung der oben angegebenen Versuche ohne weiteres zeigt.
Es wurde nun gefunden, dass Ergosterin in eine andere Substanz, nämlich Vitamin D, umgewandelt wird, wenn die Bestrahlung entsprechend intensiv vorgenommen wird. Dies kann beispielsweise durch Verlängerung der Bestrahlungsdauer, Steigerung der Inten- @ität. der Lichtquelle, feine Verteilung des Bestrahlungsgutes, zum Beispiel als Lösung, erzielt werden.
Beim Verfahren gemäss der vorliegenden Erfindung wird Ergosterin, sei es in reinem Zustande oder in Form eines durch Extraktion ergosterinhaltiger Substan zen gewonnenen Produktes, vorteilhaft in organischen Lösungsmitteln derart und so lange mit ultraviolette Strahlen enthaltendem Licht bestrahlt, bis das Ergosterin zumindest bis zu einem chemisch nachweisbaren Grad in Vitamin D umgewandelt ist; man gelangt so zu Produkten von einem Vielfachen der Wirksamkeit von bestrahltem Cholesterin und Phytosterin. Zum Beispiel gelangt man zu einem Produkt von der tausendfachen Wirksamkeit des bestrahlten Cholesterins.
Statt reines Ergosterin zu bestrahlen, kann man, wie erwähnt, mit Vorteil auch Extrakte verwenden, die das Ergosterin angereichert enthalten, zum Beispiel Hefefett oder aber Lösungen von Ergosterin in flüssigen Lö sungsmitteln.
<I>Beispiel:</I> Eine Lösung von 100 gr Ergosterin in 50 Liter Äthylalkohol wird in einem Behäl ter der Einwirkung von ultravioletten Strah len unterworfen, bis eine Probe auf Zugabe einer 1%igen Digitoninlösung nur noch eine geringe Fällung ergibt. Die ultravioletten Strahlen können zum Beispiel durch eine Quarz-Quecksilberdampflampc erzeugt wer den.
Die Art und \;leise, wie bestrahlt wird, kann natürlich eine recht, verschiedene sein. Ein gutes Ergebnis erzielt man durch Ein tauchen einer gekühlten, ultraviolettes Licht austrahlenden Lampe in die besagte Lösung, wobei während der ";a.iizeii Dauer der Reak tion Sauerstoff vollkommen ausgeselialtet sein soll.
Die a-lkoholi=clic Lösung wird nach der Bestrahlunim Vakuum auf ungefähr 11!, Liter eii:gedainpft. Durch Abkühlen der hierdurch erzielten Flüssigkeitsmenge kri stallisieren ungefähr 1.0 /o unverändertes Er gosterin aus. Nach Abtrennen des kristalli sierten Ergosterins wird die alkoholische Lö- sun ',' vollkommen im Vakuum verdampft.
Auf diese Art erhält man das Vitamin in harziger Form, und dieses Vitamin unter scheidet sich vollständig von dem als Aus gangsmaterial benutzten Ergosterin.
Um die volle Wirksamkeit des Vitamins zu erhalten, gibt man vorteilhafter-tveise zu der konzentrierten Lösung des Vitamins, wäh rend diese eingedampft wird, ein 01, das sich während der nachfolgenden Verdampfung des Alkohols nicht verfliichtigt.
Der neue Körper ist leicht löslich in Al kohol oder Ölen, und zwar in jedem Verhält nis. Der bedeutendste Unterschied gegenüber dem Ausgangsmaterial besteht darin, dar das Umw andlungsprodukt nach sorgfältiger Befreiung von Ergosterin mit Digitonin keinerlei Niederschlag ergibt. Weiterhin zeigt das bestrahlte Produkt eine andere Ab sorption des Spektrums im ultravioletten Teil. Die alkoholische Lösung des Präparates zeigt im polarisierten Licht eine leichte Rechtsdrehung, während sich die Ergosterin- Lösung als linksdrehend erweist.
Das Reak- tionsprodukt absorbiert begierig Sauerstoff, besonders bei Bestrahlung und hierdurch ent steht ein Produkt, welches keine antirachi tische Wirksamkeit besitzt. An Stelle:
ätlivl- alkoholischer Lösungen von Ergosterin kön- nen auch andere Lösungsmittel, zum Beispiel andere Alkohole. oder Benzol usw. entlia.l- tende Ergosterinlösungen mit den ultraviolet ten Strahlen behandelt werden.
Nach dem vorliegenden Verfahren kann ein Produkt mit einer antirachitischen Wirk samkeit erhalten werden, welche die des ge wöhnlichen, aktivierten Cholesterins bei wei tem übertrifft, und zum Beispiel über tau sendmal stärker ist als dieses. Die durch schnittliehe tägliche Dosis eines solchen Pro duktes beträgt für rachitische Kinder 2 bis mg. während g ewöhnliehe Cholesterin-Prä- parate, die ganz in derselben Weise vorbe handelt wurden,
in diesen Mengen überhaupt keine WirkLuig zeigen, wie Versuche ergaben.
Process for the production of a preparation with an antiracitic effect. It is known that cholesterol, phytosterol, sitosterol and ergosterol can be given a high degree of effectiveness against rickets by exposure to ultraviolet light (see, for example, Chemisches Centralblatt 1926, Il. Volume, page 289, 4, 0. Rosenheim and Th A. Webster).
Under the reaction conditions given in this literature, no chemically post-iceable conversion occurs in any of these products, not even in the case of ergosterol, as a reworking of the experiments given above readily shows.
It has now been found that ergosterol is converted into another substance, namely vitamin D, if the irradiation is carried out intensively. This can be done, for example, by lengthening the irradiation time, increasing the intensity. the light source, fine distribution of the material to be irradiated, for example as a solution.
In the method according to the present invention, ergosterol, be it in the pure state or in the form of a product obtained by extraction of ergosterol-containing substances, is advantageously irradiated in organic solvents with light containing ultraviolet rays until the ergosterol is at least chemically detectable Degree is converted to vitamin D; this leads to products which are many times more effective than irradiated cholesterol and phytosterol. For example, one arrives at a product that is a thousand times more effective than irradiated cholesterol.
Instead of irradiating pure ergosterol, one can, as mentioned, advantageously also use extracts which contain the ergosterol in enriched form, for example yeast fat or solutions of ergosterol in liquid solvents.
<I> Example: </I> A solution of 100 grams of ergosterol in 50 liters of ethyl alcohol is subjected to the action of ultraviolet rays in a container until a sample of the addition of a 1% digitonin solution shows only a small amount of precipitation. The ultraviolet rays can be generated, for example, by a quartz-mercury vapor lamp.
The way the irradiation is carried out can of course be quite different. A good result is achieved by immersing a cooled, ultraviolet light-emitting lamp in the said solution, whereby oxygen should be completely eliminated during the reaction period.
The alcoholic solution is after the irradiation in a vacuum to about 11! Liters. By cooling down the amount of liquid obtained in this way, approximately 1.0 / o unchanged gastric sterol crystallize out. After separating off the crystallized ergosterol, the alcoholic solution is completely evaporated in a vacuum.
In this way, the vitamin is obtained in resinous form, and this vitamin is completely different from the ergosterol used as the starting material.
In order to obtain the full effectiveness of the vitamin, it is advantageous to add an oil to the concentrated solution of the vitamin while this is being evaporated, which does not evaporate during the subsequent evaporation of the alcohol.
The new body is easily soluble in alcohol or oils, in any proportion. The most significant difference compared to the starting material is that the conversion product does not produce any precipitate after careful removal of ergosterol with digitonin. Furthermore, the irradiated product shows a different absorption of the spectrum in the ultraviolet part. The alcoholic solution of the preparation shows a slight clockwise rotation in polarized light, while the ergosterol solution turns out to be counterclockwise.
The reaction product eagerly absorbs oxygen, especially when irradiated, and this creates a product that has no anti-rake effect. Instead of:
Other solvents, for example other alcohols, can also be used in other alcoholic solutions of ergosterol. or benzene etc. releasing ergosterol solutions are treated with ultraviolet rays.
According to the present process, a product with an anti-rachitic activity can be obtained which by far exceeds that of the usual activated cholesterol, and is, for example, over a thousand times stronger than this. The average daily dose of such a product for rachitic children is 2 to mg. while common cholesterol preparations, which have been prepared in exactly the same way,
in these amounts no effective at all show, as experiments have shown.
