Description

Verfahren zur Herstellung eines Chininsalzes Gegenstand der- Erfindung ist die Her: Stellung einer neuen Chininverbindung, nämlich des Chininsalzes. der Cumarin-3-carbonsäure. Es wurde gefunden, daß die Verbindung des Chinins mit der Cumarin-3-carbons.äure therapeutisch wertvolle Wirkungen ausübt, die über die bloße Chininwirkung wesentlich hinausgehen. Dies war in keiner Weisse vorauszusehen, da über physiologische Wirkungen der Cumarin-3-carbonsäure bisher nichts bekannt war. Besonders deutlich ausgebildet sind die sedativen Eigenschaften der neuen Verbindung. An der Maus wirken bereits o, i mg/g der neuen Verbindung sedativ, während vom Chinin'hydrochlorid o,5 mg/g zur Erzielung der gleichen Wirkung @erforderlich sind. Ein weiterer Vorteil der neuen Chininverbindung vor dem Chinin besteht in der Herabsetzung des bitteren Geschmackes durch die Bindung an die Cumarin-3-carbonsäure.Process for the preparation of a quinine salt object of the invention is the manufacture of a new quinine compound, namely the quinine salt. the Coumarin-3-carboxylic acid. It has been found that the connection of quinine with the Coumarin-3-carboxylic acid exerts therapeutically valuable effects that go beyond the mere Quinine effect go significantly beyond. This could not have been foreseen in any way whatsoever So far nothing was known about the physiological effects of coumarin-3-carboxylic acid. The sedative properties of the new compound are particularly clear. 0.1 mg / g of the new compound have a sedative effect on the mouse, while quinine hydrochloride 0.5 mg / g are required to achieve the same effect. Another advantage The new quinine compound before quinine consists in reducing the bitter one Taste due to the binding to the coumarin-3-carboxylic acid.

Die Vereinigung des; Chinins mit der Cumarin-3-carbons;äure erfolgt nach den für die Salzbildung üblichen Methoden, wie solche in den Beispielen angeführt sind.The union of; Quinine with the coumarin-3-carboxylic acid takes place according to the methods customary for salt formation, such as those given in the examples are.

B@ei@sip-iel i 76 Gewichtsteile Cuxnarin-3-carbons,äure werden in i6oo Volumteiilen Arieton und 129,6 Gewichtsteilen wasserfreies Chinin in 2400 Volumteilen Aoeton gelöst. Die vereinigten Lösungen werden i/2 Stunde am Rüc kfluß im Sieden gehalten und ansdiließend bis zur beginnenden Kristallisation eingedampft. Nach dem Erkalten wird das Kristallisat abgesaugt, mit gekühltem Aceton ausgewasche@n und aus siedendem Wasser umkristallisiert. Es werden so 1¢6 Gewichtsedle reinen Salzes: in prachtvollen farblosen Nadehl gewonnen. Der Schmelzpunkt des lufttroekenen Materials, liegt bei 137 bis r39°.B @ ei @ sip-iel i 76 parts by weight of cuxnarin-3-carboxylic acid are dissolved in 100 parts by volume of arietone and 129.6 parts by weight of anhydrous quinine in 2400 parts by volume of aoeton. The combined solutions are refluxed for 1/2 hour and then evaporated until crystallization begins. After cooling, the crystals are filtered off with suction, washed out with cooled acetone and recrystallized from boiling water. In this way 1 ¢ 6 nobles by weight of pure salt: in splendid, colorless needle flour are obtained. The melting point of the air-dry material is 137 to r39 °.

Beispiel -- 95 Gewichtsteile Cumarin-3-ca.rbons;äure und 162 Gewichtsteile wasserfreies Chinin werden innig verrieben. Das: Gemisch wird vorsichtig bei i50° im Ölbad geschmolzen. Die erkaltete Schmelze wird konzentriert in Alkohol gelöst und das Salz durch Zusatz des vierfachen Volumens an Äther ausgefällt. Durch Umkristallisieren des abgetrennten Niederschlages aus siedendem Wasser unter -Verwendung von etwas. Tierkohle werden 96 Gewichtsteile reines Salz erhalten.Example - 95 parts by weight of coumarin-3-carbons; acid and 162 parts by weight of anhydrous quinine are thoroughly triturated. The: mixture is carefully melted at 150 ° in an oil bath. The cooled melt is concentrated in alcohol and the salt is precipitated by adding four times the volume of ether. By recrystallizing the separated precipitate from boiling water using something. Animal charcoal gives 96 parts by weight of pure salt.
