Description
Verfahren zur Darstellung einer Cholsäureverbindung. Eine Reihe von Erkrankun#gen der Gallen-Wege hat bekanntlich seine Ursache darin, daß sich in der Gallenblase zahlreiche pathogene Bakterien ansiedeln, die allen Desinfektionsversuchen widerstehen, weil es nicht gelingt, die desinfizierenden Substanzen bis an den Herd der Entzündung zu bringen.Process for the preparation of a cholic acid compound. A row of As is well known, diseases of the biliary tract are caused by the fact that the Gallbladder colonize numerous pathogenic bacteria, which all attempts to disinfect resist because it fails to get the disinfecting substances up to the stove to bring about inflammation.
Es wurde nun die bemerkenswerte Beobachtung gemacht, daß Cholsättre beim Erhitzen mit Formaldehyd eine neue Verbindung liefert, die den Formaldehyd relativ fest gebunden enthält. Das Produkt eignet sich im besonderen Maße für die Behandlung der Galle. Wahrscheinlich ist seine überraschende Wirkung nicht auf eine Desinfektion der ballenwege durch Formaldehydabspaltung zurückzuführen, sondern auf eine anregende Wirkung auf die Gallenabsonderung, wodurch gewissermaßen eine Ausspülung und Reinigung der Gallen-,vege stattfindet, die in ihrer Wirkung einer Desinfektion gleichkommt. Von den bisher gebräuchlichen Präparaten, wie z. B. den gallussauren Salzen, unterscheidet. sich das neue Präparat durch Geschmacklosigkeit und bessere Verträglichkeit. Beispiel i. looGewichtsfeile reine Cholsäure werden mit 50 Gewichtsteilen Paraformaldehyd innig verrieben und in einem offenen Gefäß 2 Stunden auf 17o bis igoo erhitzt, man läßt erkalten und löst die Reaktionsmasse in Alkohol, filtriert und läßt die Lösung in 2ooo Gewichtsteilen Eiswasser einlaufen, hierbei fällt die neue Verbindung als feines, weißes Pulver aus. Nach dem Auswaschen und Trocknen bildet sich ein weißes Pulver, das gegen 140 0 schmilzt und sich leicht in Alkohol und Eisessig löst, schwer dagegen in gebräuchlichen Koh#lenwasserstoffen. Löst man die Säure in verdünntem Ainmoniak und gibt Chlorbarium hinzu, so fällt das Bariumsalz als weißer Niederschlag aus, der abfiltriert und getrocknet wird. Aus ihm läßt sich mittels Salzsäure die Säure in reiner Form abscheiden. Beispiel 2.The remarkable observation has now been made that cholic saturation, when heated with formaldehyde, produces a new compound which contains the formaldehyde in relatively tightly bound form. The product is particularly suitable for the treatment of bile. Its surprising effect is probably not due to a disinfection of the ball passages by splitting off formaldehyde, but to a stimulating effect on the bile secretion, which in a sense rinses and cleans the bile, which is equivalent to disinfection in its effect. Of the previously used preparations such. B. the gallic acid salts. the new preparation is tasteless and better tolerated. Example i. 100 parts by weight of pure cholic acid are thoroughly triturated with 50 parts by weight of paraformaldehyde and heated in an open vessel to 17o to 10000 for 2 hours, allowed to cool and the reaction mass is dissolved in alcohol, filtered and the solution is poured into 2ooo parts by weight of ice water, the new compound falls as fine, white powder. After washing and drying, a white powder that melts at 140 0 and is readily soluble in alcohol and glacial acetic acid, hard contrast bons in common Koh # forms. If the acid is dissolved in dilute ammonia and chlorine barium is added, the barium salt separates out as a white precipitate, which is filtered off and dried. The acid can be separated from it in pure form using hydrochloric acid. Example 2.
ioo Gewichtsteile Cholsäure werden mit 5oo Gewichtsteilen Formaldehydlösung von 4o Prozent unter Druck 5 Stunden auf 170' erhitzt, man dekantiert das ölige Reaktionsprodukt mehrmals mit Wasser, nimmt in Alk-)hol auf und arbeitet die alkoholische Lösung wie im Beispiel i auf. Das so gewonnene Produkt zeigt die in Beispiel i angegebenen Eigenschaften. 100 parts by weight of cholic acid are heated to 170 ° for 5 hours with 500 parts by weight of formaldehyde solution of 40 percent under pressure, the oily reaction product is decanted several times with water, taken up in alcohol and the alcoholic solution is worked up as in Example i. The product obtained in this way shows the properties given in Example i.
Das Verfahren ist nicht an die in, den Beispielen angegebenen Mengenverhältnisse und Temperaturen gebunden.The process does not follow the proportions given in the examples and temperatures bound.
