Description
Verfahren zur Darstellung von Dihydrofollikelhormon. Gegenstand vorliegender Erfindung ist ein Verfahren zur Darstellung von Dihydrofollikel- hormon, welches dadurch gekennzeichnet ist, dass man eine Verbindung, die sich vom Fol- likelhormon der Formel C1sH2202 dadurch ab leitet, dass sie an Stelle der Hydrogylgruppe einen Rest besitzt, der bei Hydrolyse durch die Hydroxylgruppe ersetzt wird, z.
B. eine Ester- oder Äthergruppe oder Halogen, mit einer solchen metallorganischen Verbindung umsetzt, die aus ihrem organischen Rest Wasserstoff an eine Ketogruppe abgeben kann, wobei der organische Rest als ungesättigter Kohlenwasserstoff abgespalten wird, und an schliessend das gebildete Umsetzungsprodukt mit Hilfe eines hydrolysierend wirkenden Mittels aufspaltet. Bei der Aufarbeitung des Reaktionsgemisches erhält man dann Dibydro- follikelhormon der Formel C18R2402 in kri stalliner Form.
Als metallorganische Verbindungen kom men insbesondere geeignete Organomagnesium- verbindungen in Betracht, wie z. B. Isopropyl- magnesiumjodid; Propylmagnesiumjodid, Iso- butylmagnesiumjodid, Cyclohexylmagnesium- chlorid u. a. m.; vergl. hierzu auch Houben- Weyl, "Methoden der organ. Chemie", z. Band, 3. AuH., Leipzig<B>1925,</B> Seite 248.
Das erfindungsgemässe Verfahren sei im folgenden anhand beispielsweise gegebener Formelbilder näher veranschaulicht:
EMI0001.0031
<I>Beispiel:</I> 2 g Follikelhormonbenzoat vom Schmelz punkt 2l5-218 werden in 100 cm' trockenem Benzol gelöst und die Lösung im Verlaufe von 1/2 Stunde mit einer ätherischen Lösung. von Isopropylmagnesiumjodid, dargestellt aus 1,431 g Magnesiumspänen, 100 cm" trockenem Äther, 10 g Isopropyljodid und einer Spur Jod, umgesetzt. Die Reaktionsflüssigkeit wird dar auf noch etwa 11/2 Stunden am Sieden er halten und nach dem Erkalten mit Wasser und verdünnter Salzsäure zersetzt.
Das in bekannter Weise isolierte Reaktionsprodukt bildet ein rötliches, konsistentes Harz mit einem physiologischen Wirkungswert von 1 Million Mäuseeinheiten pro Gramm, in Se samöllösung geprüft.
Das Harz wird durch dreistündiges Erhitzen mit 5 o% iger methylalkoholischer Kalilauge auf dem Wasserbad verseift, die Verseifungs- flüssigkeit nach dem Erkalten mit Wasser ver dünnt, mit Salzsäure angesäuert und mit Äther extrahiert. Die ätherische Lösung wird zu nächst zwecks Abtrennung der Benzoesäure mit Soda und darauf wiederholt mit 5o/oiger wässriger Kalilauge ausgeschüttelt. Beim An säuern der vereinigten Alkaliauszüge scheidet sich ein hellbraun gefärbter, kristalliner Nie derschlag ab.
Das Präparat erweist sich mit 12 Millionen Mäuseeinheiten pro Gramm, sechsmal unterteilt in wässriger Lösung ge spritzt, im Allen Doisy-Test physiologisch als beträchtlich wirksam.
Durch fraktionierte Hochvakuumsublima- tion lässt sich daraus ein weisses Kristallisat abtrennen, dessen Eigenschaften, wie tief blau- grüne Farbe und Fluoreszenz in konzentrierter Schwefelsäure und ein physiologischer Wir kungswert von 20-25 Millionen Mäuseein heiten pro Gramm und Analysenzahlen, mit denen des bekannten Dihydrofollikelhoi-n,oi)s übereinstimmen.
Method for the preparation of dihydrofollicle hormone. The present invention relates to a process for the preparation of dihydrofollicle hormone, which is characterized in that a compound which is derived from the follicle hormone of the formula C1sH2202 in that it has a residue in place of the hydroyl group which by hydrolysis the hydroxyl group is replaced, e.g.
B. an ester or ether group or halogen, is reacted with such an organometallic compound that can release hydrogen from its organic residue to a keto group, the organic residue being split off as an unsaturated hydrocarbon, and then the reaction product formed with the aid of a hydrolyzing agent By means of splits. When the reaction mixture is worked up, dibydrofollicle hormone of the formula C18R2402 is then obtained in crystalline form.
Suitable organomagnesium compounds are particularly suitable as organometallic compounds, such as. B. isopropyl magnesium iodide; Propylmagnesium iodide, isobutylmagnesium iodide, cyclohexylmagnesium chloride u. a. m .; See also Houben-Weyl, "Methods of organic chemistry", z. Volume, 3rd AuH., Leipzig <B> 1925, </B> page 248.
The method according to the invention is illustrated in more detail below with the aid of, for example, given formula images:
EMI0001.0031
<I> Example: </I> 2 g of follicular hormone benzoate with a melting point of 2l5-218 are dissolved in 100 cm 'of dry benzene and the solution with an ethereal solution over the course of 1/2 hour. of isopropylmagnesium iodide, made up of 1.431 g of magnesium shavings, 100 cm "of dry ether, 10 g of isopropyl iodide and a trace of iodine. The reaction liquid is then kept boiling for about 11/2 hours and, after cooling, is decomposed with water and dilute hydrochloric acid .
The reaction product, isolated in a known manner, forms a reddish, consistent resin with a physiological action value of 1 million mouse units per gram, tested in seed oil solution.
The resin is saponified by heating for three hours with 50% strength methyl alcoholic potassium hydroxide solution on a water bath, the saponification liquid is diluted with water after cooling, acidified with hydrochloric acid and extracted with ether. The ethereal solution is first extracted with soda to separate off the benzoic acid and then repeatedly with 50% aqueous potassium hydroxide solution. When the combined alkali extracts are acidified, a light brown colored, crystalline precipitate is deposited.
With 12 million mouse units per gram, divided six times in an aqueous solution, the preparation proves to be physiologically considerably effective in the Allen Doisy test.
A white crystallizate can be separated from it by fractional high vacuum sublimation, the properties of which, such as deep blue-green color and fluorescence in concentrated sulfuric acid and a physiological effect value of 20-25 million mouse units per gram and analysis numbers, match those of the well-known dihydrofollicle n, oi) s match.
