Description

Verfahren zur Darstellung von leicht löslichen Doppelsalzen aus monomethyl-, Dimethyl- und Trimethylxanthinen. Der Verwendung der diuretisch wirkenden Basen der Coffeinreihe, insbesondere des Theobromins, stand die schwere Resorbierbarkeit und die Schwerlöslichkeit der Verbindungen im Wege. Diese Schwierigkeit wurde in Ansehung des Theobr omins und Coffeins durch die Darstellung leicht löslicher Doppelsalze mit Natriumsalicylat, wie z. B. des Theobrominnatrium - Natriumsalicylats, behoben.Process for the preparation of easily soluble double salts from monomethyl, Dimethyl and trimethyl xanthines. The use of the diuretic bases the caffeine series, especially theobromine, was due to the difficulty of absorbing it and the poor solubility of the compounds in the way. This difficulty was found in Appreciation of theobromine and caffeine through the presentation of easily soluble double salts with sodium salicylate, such as. B. of theobromine sodium - sodium salicylate.

Nach dem Verfahren der britischen Patentschrift Nr. 26838/19o6 wurde auch Milchsäure als zweite Komponente der Doppelsalze verwendet und auf diese Weise Theobrominnatrium-Natriumlactat hergestellt. Dieses Präparat weist neben größerer Löslichkeit auch eine Verstärkung der diuretischen Wirkung auf. Diese Verbindung ist aber nicht frei von unangenehmen Nebenwirkungen (vgl. Pharmazeutische Zeitung5a, 1907, S. d.9). Man hat ferner versucht, die Tatsache zu verwerten, daß Coffein und Theophyllin auch mit Erdalkalisalzen der aromatischen Carbonsäuren komplexe Verbindungen bilden, die zum Teil in der Therapie Verwendung finden können (vgl. Chemisches Zentralblatt r929, Bd. III, S. 957).Following the procedure of British patent specification No. 26838/19o6 was also used lactic acid as the second component of the double salts and this way Theobromine Sodium Lactate. This preparation shows in addition to larger Solubility also increases the diuretic effect. This connection but is not free from unpleasant side effects (cf.Pharmaceutical Gazette5a, 1907, p. D.9). Attempts have also been made to exploit the fact that caffeine and Theophylline also contains complex compounds with alkaline earth salts of aromatic carboxylic acids which can partly be used in therapy (see Chemisches Zentralblatt r929, Vol. III, p. 957).

Den Gegenstand der vorliegenden Erfindung bildet nun ein Verfahren -_zitr - Darstellung von Doppelsalzen der Calciumverbindungen von Monomethyl-, Dimethyl- und Trimethvlxanthinen mit Caloiitmlactat. Derartige Doppelsalze zeigen die verstärkte Wirkung aller drei .Komponenten, indem sie einerseits die blutdrucksenkende und diuretische Wirkung des Theobromins und der verwandten Verbindungen und gleichzeitig die styptische Wirkung der Calciumsalze besitzen, ohne wie bisher durch schwer abzubauende aromatische 'Carbonsäuren belastet zu sein, da die Milchsäure im Organismus vollständig verbrannt wird. Diese neuen Präparate haben daher einen gesteigerten therapeutischen Wert. Auch die Löslichkeitsverhältnisse dieser Doppelsalze, deren eine Komponente Calciumlactat ist, liegen besondes günstig. Gegenüber dem bekannten Theobrominnatrium-Natriumlactat zeigen die neuen Verbindungen überraschenderweise den Vorteil, daß sie dank dem Ersatz des Natriums durch Calcium keine unangenehn ien Nebenwirkungen aufweisen.The subject of the present invention now forms a method -_zitr - representation of double salts of the calcium compounds of monomethyl-, dimethyl- and trimethylxanthines with calicoitm lactate. Such double salts show the strengthened Effect of all three .components, on the one hand the antihypertensive and diuretic action of theobromine and related compounds and at the same time have the typical effect of calcium salts without, as has been the case up to now, difficult to break down aromatic 'carboxylic acids, since the lactic acid is completely in the organism is burned. These new preparations therefore have an increased therapeutic Value. Also the solubility ratios of these double salts, one of which is a component Calcium lactate is particularly beneficial. Compared to the well-known theobromine sodium-sodium lactate show the new compounds surprisingly the advantage that they thanks to the Replacement of sodium by calcium does not have any unpleasant side effects.

Beispiel. a Mol. Theobromin werden mit r Mol. reinen Calciumoxyds (Kalk aus Marmor) vermischt und mit wenig Wasser angerührt. Hierauf wird frisch umkristallisiertes, noch feuchtes milchsaures Calcium eingetragen, und zwar in einer Menge, die 2 Mol. des entwässerten Calciuinlactats auf r Mol. Theobroinincalcium entspricht. Das Gemisch wird sodann auf dein Wasserbad, allenfalls unter weiterem Zusatz von ein wenig Wasser, bis zur Lösung erhitzt und gegebenenfalls hernach von den geringen Verunreinigungen rasch abfiltriert, erstarren gelassen und im Vakuum getrocknet, bis sich das Salz (Theobromincalcium+2 Mol. Calciumlactat) leicht pulverisieren läßt. Ebenso kann auch die Doppelverbindung des Theobromincalciums mit r Mol. Calciumlactat hergestellt werden. In 'genau derselben Weise kann man z. B. zu Verbindungen des Theophyllincalciums, Paraxanthincalciums und Coffeincalciums mit 2 Mol. milchsaurem Calcium und r Mol. milchsaurem Calcium gelangen.Example. a mole of theobromine is obtained with r mole of pure calcium oxide (Lime from marble) mixed and mixed with a little water. Then it gets fresh recrystallized, still wet lactic acid calcium entered, namely in an amount that 2 moles of the dehydrated calcium lactate to r moles. Corresponds to theobroinine calcium. The mixture is then on your water bath, if necessary with further addition of a little water, heated to solution and if necessary then quickly filtered off the minor impurities and allowed to solidify and dried in vacuo until the salt (theobromine calcium + 2 mol. calcium lactate) easy to pulverize. Likewise, the double compound of theobromine calcium can also be used be made with r moles of calcium lactate. In exactly the same way one can z. B. to compounds of theophylline calcium, paraxanthine calcium and caffeine calcium with 2 mol. of lactic acid calcium and r mol. of lactic acid calcium.
