Description

Verf ahren zur Herstellung und Gewinnung einer antibiotisch wirkenden, Verbindung Im Patent 958 241 ist ein Verfahren zur Herstellung bzw. Gewinnung einer antibiotischen Verbindung und ihrer Salze beschrieben. Das Besondere dieses Verfahrens besteht darin, daß ein Streptomycesstamm in einer wäßrigen kohlehydrathaltigen. Nährlösung, und zwar zweckmäßig unter submersen Bedingungen und unter Belüftung gezüchtet wird, bis die Nährlösung erhebliche antibakterielle Wirksamkeit gegen grampositive Mikroorganismen aufweist, worauf die antibiotische Verhindung Amphomycin bzw. deren Salze, aus der Nährlösung isoliert werden.Process for producing and obtaining an antibiotic compound. Patent 958 241 describes a process for producing or obtaining an antibiotic compound and its salts. The special feature of this process is that a Streptomyces strain in an aqueous carbohydrate-containing. Nutrient solution, expediently grown under submerged conditions and with aeration, until the nutrient solution has considerable antibacterial activity against gram-positive microorganisms, whereupon the antibiotic prevention amphomycin or its salts are isolated from the nutrient solution.

Die vorliegende Erfindung betrifft eine weitere Verbesserung des Verfahrens nach dem Hauptpatent, und zwar dahingehend, daß das anfallende Ampho#mycin in das CaleiurnsaJz übergeführt wird. Es zeigt sich, daß auf diesem Wege besandeTe Vorteile erzielbar sind, weil das Caleiumsalz aus Amphomycin in kristalliner Form gewonnen werden kann, so. daß sich nicht nur eine leichtere und wirksaniere, Reinigung des Produktes eirgibt, sondern vor allem. auch die Dosierung der Substanz exakter kontrolliert werden kann. Beispiel I Aus Nährflüssigkeit wird Amphomyc,in bei einem pl, von 210, gegebenenfalls unter Verwendung von Salzsäure, mit Butanol extrahlert Der Butanol-Amphomycin-Extrakt wird mit Wasser gewaschen. Dann wird Natrium- oder Ammo-niurnhydroxyd bis zu,einem PH von. 6 bis 7 beigegeben und azeotrop eingeengt# bis ein Konzentrat von etwa, 50 bis 150 mg/rnl erzielt ist. Zum Konzentrat wird eine wäßrige Caleiumchloridlösung gegeben, die 10 bis 15 Gewichtsprozent Calciurnchlo#rid und etwa 15 bis 20 Gewichtsprozent Wasser enthält. Das sich niederschlagende Ca,Iciun-isalz wird abfiltriert, zwecks Entfernung etwaiger Niederschläge. aus Natrium- oder Ammoniunichlorid mit einer Wasser-Methanol-Lösung und anschließend mit Methanol gewaschen. und schließlich im Vakuum getrocknet.The present invention relates to a further improvement of the process according to the main patent, namely to the effect that the amphomycin that is produced is converted into the calories. It has been shown that advantages can be achieved in this way, because the calcium salt can be obtained in crystalline form from amphomycin, see above. that there is not only an easier and more effective cleaning of the product, but above all. the dosage of the substance can also be controlled more precisely. EXAMPLE I Amphomyc is extracted from nutrient fluid with butanol, in a pl, of 210, if necessary using hydrochloric acid. The butanol-amphomycin extract is washed with water. Then sodium or ammonium hydroxide is added to a pH of. 6 to 7 are added and concentrated azeotropically until a concentrate of approx. 50 to 150 mg / ml is achieved. An aqueous calcium chloride solution containing 10 to 15 percent by weight of calcium chloride and about 15 to 20 percent by weight of water is added to the concentrate. The precipitating calcium carbonate salt is filtered off in order to remove any precipitates. from sodium or ammonium chloride with a water-methanol solution and then washed with methanol. and finally dried in vacuo.

Beispiel II Eine vorzugsweise weniger als 2011/oige, Natrium-Amphomycin-Lösung wird mit dem gleichen Volumen Isopropyl-Alkohol verdünnt. Man gibt dann der Lösung sehr langsam unter intensiver Bewegung ein gleiches Volumen an 2,5 % Ca, C12 - 2 H2 0 in 50 1/o Isopropanol-Wasser zu. Es bildet sich kristallines Caleium-Ampho,rnycin, das nach. 2- bis 3stündigem Rühren abfiltriert wird. Der Kuchen wird nun durch Suspendierung in Methanol gewaschen, erneut filtriert und luftgetrocknet.Example II A sodium amphomycin solution, preferably less than 2011%, is diluted with the same volume of isopropyl alcohol. An equal volume of 2.5 % Ca, C12-2 H2 0 in 50 1 / o isopropanol-water is then added to the solution very slowly with intensive agitation. Crystalline Caleium-Ampho, rnycin is formed, which after. 2 to 3 hours of stirring is filtered off. The cake is then washed by suspension in methanol, filtered again and air-dried.
