Description

17ß-Hydroxy-18-methyl-4,15-östradien-3on,17β-Hydroxy-18-methyl-4,15-estradien-3one,

Verfahren zu seiner Herstellung und diese Verbindung enthaltende pharmazeutische Präparate.Process for its preparation and pharmaceutical products containing this compound Preparations.

Die Erfindung betrifft den in den Patentansprüchen gekennzeichneten Gegenstand.The invention relates to that characterized in the claims Object.

Das erfindungsgemäße 17ß-Hydroxy-4, 15-östradien-3-on besitzt eine ausgeprägte progestative, östrogene und antihypercholestereme Wirksamkeit und kann demzufolge als Wirkstoff in pharmazeutischen Präparaten verwendet werden.The 17ß-hydroxy-4, 15-estradien-3-one according to the invention has a pronounced progestative, estrogenic and antihypercholesteremic effectiveness and can can therefore be used as an active ingredient in pharmaceutical preparations.

Das erfindungsgemäße Verfahren zur Herstellung der 17ß-Hydroxy-4,I5-östradien-3-ons wird unter den Bedingungen durchgeführt, die man üblicherweise bei der mikrobiologischen Umsetzung von Steroiden anwendet.The process according to the invention for the preparation of the 17β-hydroxy-4,15-estradien-3-ones is carried out under the conditions that are usually found in microbiological Implementation of steroids.

Unter den üblicherweise verwendeten Kulturbedingungen werden in einem geeigneten Nährmedium unter Belüften, Submerskulturen angezüchtet. Dann setzt man den Kulturen das 18-Methyl-4,15-östradien-3,17-dion (in einem Lösungsmittel gelöst oder vorzugsweise in emulgierter Form) zu und fermentiert bis eine maximale Substratumwandlung erreicht ist.Under the commonly used culture conditions are in a suitable nutrient medium with aeration, submerged cultures. Then you bet the cultures the 18-methyl-4,15-estradiene-3,17-dione (dissolved in a solvent or preferably in emulsified form) and fermented until a maximum substrate conversion is reached.

Geeignete Substratlösungsmittel sind beispielsweise Methanol, Äthanol, Glykolmonomethyläther, Dimethylformamid oder Dimethylsulfoxyd. Die Emulgierung des Substrates kann beispielsweise bewirkt werden, indem man dieses in mikronisierter Form oder in einem mit Wasser mischbaren Lösungsmittel (wie Methanol, Äthanol, Aceton, Glykolmnomethyläther, Dimethylformamid oder Dimethylsulfoxyd) gelöst unter starker Turbulenz in (vorzugsweise entkalktem) Wasser, welches die üblichen Emulgationshilfen enthält, eindüst.Suitable substrate solvents are, for example, methanol, ethanol, Glycol monomethyl ether, dimethylformamide or dimethyl sulfoxide. The emulsification of the Substrates can for example be effected by micronized Form or in a water-miscible solvent (such as methanol, ethanol, acetone, Glykolmnomethyläther, Dimethylformamide or Dimethylsulfoxyd) dissolved under strong Turbulence in (preferably decalcified) water, which the usual emulsification aids contains, inject.

Geeigneten Emulgationshilfen sind nichtiogene Emulgatoren, wie zum Beispiel Äthylenoxyaddukte oder Fettsäureester von Polyglykolen. Als geeignete Emulgatoren seien die handelsüblichen Netzmittel Tegin@, Tweens und Spane beispielsmäßig genannt.Suitable emulsification aids are non-halogenated emulsifiers, such as Example ethyleneoxy adducts or fatty acid esters of polyglycols. As suitable emulsifiers the commercial wetting agents Tegin @, Tweens and Spane are exemplary called.

Die optimale Substratkonzentration, Substratzugabezeit und Fermentationsdauer ist von den angewendeten Fermentationsbedingungen abhängig. Diese Größen müssen, wie dies bei mikrobiologischen Steroidumwandlungen allgemein erforderlich ist, im Einzelfall durch Vorversuche, wie sie dem Fachmann geläufig sind, ermittelt werden.The optimal substrate concentration, substrate addition time and fermentation time depends on the fermentation conditions used. These sizes must as is generally required in microbiological steroid conversions, im Individual cases can be determined by preliminary tests, as they are familiar to the person skilled in the art.

Es ist für den Fachmann überraschend, daß bei dem erfindungsgemäßen Verfahren nur die 17-Ketogruppe reduziert wird, nicht aber die ebenfalls konjugierte Ketogruppe in der 3-Position.It is surprising to the person skilled in the art that in the inventive Only the 17-keto group is reduced in the process, but not the conjugated group Keto group in the 3-position.

Das nachfolgende Beispiel dient zur Erläuterung des erfindungsgemäßen Verfahrens.The following example serves to explain the invention Procedure.

Beispiel 500 ml Erlenmeyerkolben werden mit je 100 ml einer Nährlösung aus 3,0 % Glukose, 1,0 % Corn steep liquor, 0,2 % NaNO31 0,1 % WH2P04, 0,2 °%0 K2HP04, 0,05 O/o MgS04, 0,002 % FeS04 und 0,05 % KC1 oder einer einfacheren Nährlösung aus 2,0 % Glukose und 2,0 % Corn steep beschickt und bei 120 °C 30 Min. im Autoklaven sterilisiert. (pH-Wert vor der Sterilisation 6,0, nach Sterilisation pH 5,7). Die Kolben werden mit der Abschwemmung jeweils einer zwei Wochen alten Schrägagarkultur (Malz- oder Hafermehlagar) von Sistotrema brinkmanii CBS 72769 beimpft und Tage 3 auf einer Rotationsschüttelmaschine mit einer Frequenz von 120 U/Min. bei 23°C geschüttelt. Die gutentwickelten Kulturen werden als Inoculum verwendet zur Beimpfung von 21 Erlenmeyerkolben gefüllte mit 500 ml einer sterilen Nährlösung aus 3,0 % Glukose, 1,0 % Cornsteep liquor, 0,2 % NaNO3, 0,1 % KH2PO4, 0,2 % K2HPO4, 0,05 % MgS04, 0,002 % FeSO4 und 0,05 % KC1.Example 500 ml Erlenmeyer flasks are each filled with 100 ml of a nutrient solution from 3.0% glucose, 1.0% corn steep liquor, 0.2% NaNO31 0.1% WH2P04, 0.2% 0 K2HP04, 0.05% MgS04, 0.002% FeS04 and 0.05% KC1 or a simpler nutrient solution 2.0% glucose and 2.0% corn steep charged and at 120 ° C for 30 minutes in the autoclave sterilized. (pH value before sterilization 6.0, after sterilization pH 5.7). the Flasks are washed away with a two week old agar slant (Malt or oatmeal agar) inoculated from Sistotrema brinkmanii CBS 72769 and days 3 on a rotary shaker at a frequency of 120 rpm. at 23 ° C shaken. The well developed cultures are used as inoculum for inoculation of 21 Erlenmeyer flasks filled with 500 ml of a sterile nutrient solution of 3.0% Glucose, 1.0% Cornsteep liquor, 0.2% NaNO3, 0.1% KH2PO4, 0.2% K2HPO4, 0.05% MgS04, 0.002% FeSO4 and 0.05% KC1.

Die Kolben werden wiederum bei 23 OC und 120 U/Min. geschüttelt und nach einer Anwachsphase von 6 Stunden mit jeweils einer sterilfiltrierten Lösung von 100 mg 18-Methyl-4,t5-östradien-3,17-dion in 1,5 ml Dimethylformamid versetzt. Die Umwandlung wird durch Intervallproben kontrolliert, deren Essigesterextrakte durch DC (Silikagelplatten Merck), System Chloroform/Methanol 9 + 1 analysiert werden.The pistons are turned again at 23 OC and 120 rpm. shaken and after a growth phase of 6 hours with a sterile-filtered solution each time 100 mg of 18-methyl-4, t5-estradiene-3,17-dione in 1.5 ml of dimethylformamide are added. The conversion is controlled by interval samples, their ethyl acetate extracts can be analyzed by TLC (silica gel plates Merck), system chloroform / methanol 9 + 1.

Nach erfolgter Umwandlung (156 bis 356 Stunden Kontaktzeit, analytische Ausbeute 60 % 17ß-Alkohol) werden die Kulturbrühen jeweils zweimal mit je 500 ml Essigester estrahiert und die Extrakte im Vakuum eingedampft. Die Rohprodukte mehrerer Ansätze werden vereinigt und durch präparative Dünnschichtchromatographie an Kieselgel-Fertigplatten (60F/ 254 Merck) unter 5maliger Entwicklung mit dem System Chloroform/Methynol 98 + 2 aufgereinigt. Es werden nach Umkristallisieren aus Isopropyläther erhalten 269 mg 17ß-Hydroxy-18-methyl-4, 15-östradien-3-on, Schmelzpunkt 164/165-166 Unter den gleichen Bedingungen wird die Reduktion durchgeführt mit den Stämmen: Sistotrema brinkmannii CBS 40254 " tr CBS 34153 " " CBS 16060 " II CBS 15438 " VI CBS 34053 " II CBS 40154 " oblongispora CBS 39563 II 1I CBS 39763 Trechospora raduloides CBS 16365After conversion (156 to 356 hours contact time, analytical Yield 60% 17 [beta] alcohol), the culture broths are each twice with 500 ml each Ethyl acetate extracted and the extracts evaporated in vacuo. The raw products of several Approaches are combined and prepared by preparative thin layer chromatography on silica gel plates (60F / 254 Merck) developing 5 times with the system Chloroform / Methynol 98 + 2 cleaned up. After recrystallization from isopropyl ether, 269 are obtained mg of 17β-hydroxy-18-methyl-4, 15-estradien-3-one, melting point 164 / 165-166 Under The reduction is carried out under the same conditions with the strains: Sistotrema brinkmannii CBS 40254 "tr CBS 34153" "CBS 16060" II CBS 15438 "VI CBS 34053 "II CBS 40154" oblongispora CBS 39563 II 1I CBS 39763 Trechospora raduloides CBS 16365
