Description

  

  Verfahren zur Herstellung einer wässerigen     Digitalislanata-Glykosidlösung.       Es wurde festgestellt, dass das wasser  lösliche     ss-Pyridincarbonsäurediäthylamid    er  möglicht aus     Digitalislanata-Glykosid        (Lana-          digin)    eine wässerige     Digitalislanata-Glykosid-          lösung    herzustellen, indem der dreiwertige       Stickstoff    im     Pyridinkern    des     P-Pyridincarbon-          säurediäthylamids    offenbar die Tendenz hat,  in den fünfwertigen Stickstoff überzugehen,

    auf diese Art basisch wirkt und so die sauren  Gruppen des     Lanadigins    an sich zu addieren  vermag. Der so entstehende neue Körper ist  wasserlöslich, jedoch in Lösung weitgehend  hydrolytisch gespalten.  



  Das Verfahren gemäss der Erfindung zur  Herstellung einer in der Medizin verwend  baren     farb-    und geruchlosen,     bitterschmecken-          den,    wässerigen     Digitalislanata-Glykosidlö-          sung    ist dadurch gekennzeichnet, dass man       Digitalislanata-Glykosid,        ss-Pyridincarbon-          säurediäthylamid    und Wasser zusammen gibt.  



  Das für die Erzielung der Lösung zu ver  wendende     ss-Pyridincarbonsäurediäthylamid     zeigt auch eine nützliche physiologische Wir  kung.  



  Die erfindungsgemäss erhaltenen Lösungen  können, wie Versuche ergaben, stark abge-    kühlt und nachträglich verdünnt werden, ohne  dass gelöste Substanz zur Ausscheidung kommt,  und zwar auch bei hochprozentigem Zusatz an  derer     Stoffe,    wie Traubenzucker, Kochsalz     etc.     <I>Beispiel:</I>  Durch Hinzufügen von 25     eins    einer     250%igen     Lösung von     ss-Pyridincarbonsäurediäthylamid     in Wasser von Zimmertemperatur zu 0,025 g       Digitalislanata-Glykosid(Lanadigin)    wird eine  klare, farblose, 0,1     0;

  oige        Lanadiginlösung    er  halten, die sich auch unter 0 0 abkühlen lässt,  ohne zu erstarren oder Substanz auszuschei  den. Nachträgliches Hinzufügen von Wasser  zu obiger Lösung bewirkt ebenfalls keine Aus  fällung. In reinem Wasser von Zimmertempe  ratur löst sich     Digitalislanata-Glykosid    allein  nur bis zirka     0,010o.  



  Process for the preparation of an aqueous digitalislanata glycoside solution. It was found that the water-soluble ß-pyridinecarboxylic acid diethylamide enables an aqueous digitalislanata glycoside solution to be produced from digitalislanata glycoside (lanadigin), in that the trivalent nitrogen in the pyridine nucleus of the P-pyridinecarboxylic acid diethylamide apparently has the tendency in the to pass over pentavalent nitrogen,

    acts basic in this way and thus is able to add the acidic groups of the lanadigins per se. The resulting new body is water-soluble, but largely hydrolytically split in solution.



  The method according to the invention for producing a colorless and odorless, bitter-tasting, aqueous digitalislanata glycoside solution which can be used in medicine is characterized in that digitalislanata glycoside, β-pyridinecarboxylic acid diethylamide and water are added together.



  The s-pyridinecarboxylic acid diethylamide to be used to achieve the solution also shows a useful physiological effect.



  The solutions obtained according to the invention can, as tests have shown, be strongly cooled and subsequently diluted without the dissolved substance being excreted, even with a high percentage of other substances such as dextrose, table salt etc. <I> Example: </ I> By adding 25% of a 250% solution of ß-pyridincarboxylic acid diethylamide in water at room temperature to 0.025 g of digitalislanata glycoside (lanadigin), a clear, colorless, 0.1%;

  The above lanadigin solution is obtained, which can also be cooled below 0 0 without solidifying or excreting substance. Subsequent addition of water to the above solution also does not cause any precipitation. In pure water at room temperature, digitalislanata glycoside only dissolves to around 0.010o.
