VERFAHREN ZUR HERSTELLUNG VON GLYKOSIDEN DES DAMMARAN-TYPSPROCESS FOR THE PREPARATION OF GLYCOSIDES OF THE DAMMARAN TYPE

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Glykosiden des Da mm ar an-T yp s.The invention relates to a process for the production of glycosides of the Da mm ar an type.

Unter der Fülle der b i ο I og i sch -ak t i ν en Verbindungen, die in Ginseng vorkommen, ist eine besondere Gruppe von Saponinen besonders interessant. Diese Gruppe wird von der Tr i t e rp en oide η des Dammar an-Typs gebildet, die an den Stellen 3, 6 oder 20 des Kohlenstoffkerngerüstes mit Zuckern verknüpft sind. Hinsichtlich der pharmazeutischen Wirkung dieser Saponine sei verwiesen auf Kaku et al. , Arzneimittel Forschung ( Drug Res ) 25,3, ( 1975 ), Seite 343. Diese Saponine kommen nach dem bisherigen Wissenstand lediglich in der Ginsengwurzel ( Panax Ginseng C.A. Meyer ) vor und sind mithin in größeren Mengen nicht erhältlich, was dazu führt, daß sie im größeren Maße für therapeutische und andere Zwecke nicht zu Verfügung stehen, obgleich, wie a.a.O beschrieben, Extahierung und Erforschung ihres Aufbaus und ihres therapeutischen Wirkungsspektrums voll im Gange ist.Among the abundance of b i ο I og i sch -ak t i ν en connections that in Ginseng occur, a special group of saponins is particularly interesting. This group is called by the Tr i t e rp en oide η of the dammar an-type, which are formed at positions 3, 6 or 20 of the carbon core structure are linked to sugars. Regarding the pharmaceutical effects of these saponins see Kaku et al. , Drug Research (Drug Res) 25.3, (1975), page 343. Those saponins are coming according to the current state of knowledge, only in the ginseng root (Panax Ginseng C.A. Meyer) and are therefore not available in larger quantities, which means that they are in larger Dimensions not available for therapeutic or other purposes stand, although, as described above, extahing and exploring its structure and its therapeutic The spectrum of activity is in full swing.

[« liegen Berichte vor, wonach Triterpenalkohole aus Birken blättern isoliert wurden; Franz Gottwald Fischer und Nikolaus Seiler, Liebigs Ann. Cliem. , Bd. 626, Seite 185-205 und Bd. 644, Seite 146-162, wobei anzumerken wäre, daß diese Art von Triterpenoiden zuerst aus dem Dammarharz isoliert wurde. Es handelt sich bei den Triterpenalkoholen aus Birkenblättern mit h in um solche des Dammaran-Typs.There are reports that triterpene alcohols from Birch leaves have been isolated; Franz Gottwald Fischer and Nikolaus Seiler, Liebigs Ann. Cliem. , Vol. 626, pages 185-205 and Vol. 644, Pages 146-162, it being noted that this type of triterpenoid first came from the dammar resin was isolated. It is the triterpene alcohols made of birch leaves with h in around those of the Dammaran type.

Es wurde nunmehr überraschenderweise erkannt, daß die Triterpenalkohole aus Pflanzenblättern, insbesonders Birkenblättern, den bisherigen Engpaß auf der Versorgung mit Glykosiden des Dammaran-Typs - die wie erwähnt, bisher nur aus Ginseng gewonnen werden konnten- auf einfache Weise dadurch behoben wird, daß man erfindungsgemäß die in praktisch unbegrenzter Menge zur Verfügung stehenden Triterpenalkohole aus Pflanzenblättern in Glykoside des Dammaran-Typs durch Verknüpfung mit Zuckerresten überführt.It has now been found, surprisingly, that the Triterpene alcohols from plant leaves, especially birch leaves, the previous bottleneck in the supply with glycosides of the Dammaran type - which, as mentioned, could previously only be obtained from ginseng is solved in a simple manner that according to the invention the triterpene alcohols available in practically unlimited quantities from plant leaves in Glycosides of the Dammaran type transferred by linking with sugar residues.

Mit dem erfindungsgemäßen Verfahren ist es also möglich eine ausreichende Versorgung mit Glykosiden des Dammaran-Typs sicherzustellen. Die erfindungsgemäße Halbsynthese bringt nicht nur insoweit wirtschaftliche Vorteile, sondern sie bietet vielmehr auch die Möglichkeit ohne große Schwierigkeit in bekannter Weise völlig neue Glykoside herzustellen und zwar solche, die evtl. nicht in der Natur vorhanden sind. Da mit der Erfindung nunmehr große Mengen der interssierenden, praktisch reinen Glykoside, inbesondersIt is therefore possible with the method according to the invention to ensure an adequate supply of glycosides of the dammaran type. The semi-synthesis according to the invention brings not only economic advantages, but Rather, it also offers the possibility of completely new glycosides in a known manner without great difficulty to produce, namely those that may not exist in nature. Since with the invention now large quantities the interesting, practically pure glycosides, in particular

Saponine, zur Verfügung gestellt werden können, können auch Großversuche zur völligen Erfassung des therapeutischen Effektes der interessanten Glykoside unternommem werden.Saponins, which can be made available, can also be used for large-scale experiments to fully capture the therapeutic The effect of the interesting glycosides can be undertaken.

Erfindungsgemäß werden die T r i t erpe na Ik oh öl e vorzugsweise aus Birkenblättern isoliert, da es sich gezeigt hat, daß sie in diesen Blättern mit einem vergleichweise hohen Anteil vertreten sind, nämlich bis zu 10 Gew.-% der Trockensubstanz .According to the invention, the T ri t erpe na Ik oh oil e are preferred isolated from birch leaves as it has been shown they in these sheets with a comparatively high Proportion are represented, namely up to 10 wt .-% of the dry substance.

U.a. aus der obenerwähnten Arbeit von Kaku et al. ist es bereits jetzt bekannt, daß Saponine von Panax Ginseng C.A. Meyer eine beträchtliche ZNS ( Zentralnervensystem )-Aktivität besitzen.From the above-mentioned work by Kaku et al. is it already known that saponins from Panax Ginseng C.A. Meyer has considerable CNS (central nervous system) activity own.

Je nach Art des Saponins tritt eine hemmende, stimulierende, beruhigende, Schmerzstillende und muskelentspannende Wirkung auf. Bei Versuchstieren löst bereits eine Dosis von 2,5- 5 mg/ kg Wirkung aus. Dabei spielen die " Ginsenoside " RgI und RbI eine zentrale Rolle. Verhalten und Lernvorgänge von Tieren werden eindeutig beeinflußt und zwar auf eine bisher noch nicht erforschte, günstige Weise.Depending on the type of saponin, an inhibiting, stimulating, calming, pain relieving and muscle relaxing effect on. In test animals, a dose of 2.5-5 mg / kg already dissolves Effect. The "ginsenosides" RgI and RbI plays a central role. Behavior and learning processes of animals are clearly influenced and that on one as yet unexplored, inexpensive way.
