      Verfahren    zur Herstellung eines     acylierten        Dihydrofollikelhormons.     
EMI0001.0004     
  
    Cxegensta.nd <SEP> vorliegender <SEP> Erfindung <SEP> ist
<tb>  (in <SEP> -\"erfahren <SEP> zur <SEP> Herstellung <SEP> eines <SEP> acylier  ten <SEP> Dihydrofollikelhormons, <SEP> das <SEP> dadurch <SEP> e  henazeichnet <SEP> ist, <SEP> dass <SEP> man <SEP> Dihydrofollikel  hormon <SEP> vom <SEP> Smp. <SEP> 174' <SEP> C <SEP> mit <SEP> einem <SEP> aeety  licrenden <SEP> Mittel <SEP> behandelt.
<tb>  Die <SEP> neue <SEP> Verbindung, <SEP> das <SEP> Diacetyldi  h\-cli-ofollil@elliormon, <SEP> die <SEP> als <SEP> Arzneimittel
<tb>  @"ericendung <SEP> finden <SEP> soll, <SEP> kristallisiert <SEP> in <SEP> wei  chci:

  . <SEP> glänzenden, <SEP> fettigen <SEP> Blättchen <SEP> vom
<tb>  Snip. <SEP> 1.20 <SEP> bis <SEP> 121 <SEP>   <SEP> C.
<tb>  Neben <SEP> dieser <SEP> Verbindung <SEP> entsteht. <SEP> bei
<tb>  dem <SEP> Verfahren <SEP> noch <SEP> ein <SEP> Monoacetat <SEP> vom
<tb>  Sinli. <SEP> ?10 <SEP> bis <SEP> \?13 <SEP>   <SEP> C.
<tb>  <I>.Bespiel:</I>
<tb>  1 <SEP> g <SEP> I)ihyd <SEP> rofollikelhormon <SEP> vorn <SEP> Schmelz  punlit <SEP> <B>172</B> <SEP> bis <SEP> <B>1,73</B> <SEP>   <SEP> wird <SEP> in <SEP> wenig <SEP> reinem       Essig gelöst und die Lösung unter Eisküh  lung mit 100     ein"    eines käuflichen     Eisessig-          Bromwasserstoffgemisches    übergossen.

   Die       l@eaktionslösung    nimmt dabei zunächst eine  goldgelbe Färbung an. die sich allmählich    etwas vertieft. Nach etwa zweitägigem  Stehen giesst man die Reaktionslösung, die  nunmehr völlig klar ist und keine Spuren  ungelösten     Kristallisates    mehr enthält, in  zirka 500     cm2    Eiswasser. Der dabei ausge  fallene weisse. flockige Niederschlag wird  in Äther aufgenommen. die ätherische Lö  sung nacheinander mit     5%iger    wässeriger       Sololösung    und Wasser durchgeschüttelt,  dann getrocknet und abgedämpft.

   Der ver  bleibende konsistente ölige Rückstand zeigt  in     konzentrierter        Schwefelsäurelösung    im  Gegensatz zum Ausgangsmaterial, das darin  gelöst leuchtend blau fluoresziert, unter der  Analysenquarzlampe eine rein goldgelbe  Farbe und Fluoreszenz.  



  Dieses ölige Produkt wird zur Trennung  des in ihm enthaltenen Mono- und     Diacetyl-          dihy        drofollikelhormons    aus     methylalkoholi-          scher    Lösung mit Wasser ausgefällt und der  erhaltene Kristallkuchen     (Smp.   <B>173</B> bis 174'  nach allmählicher vorangehender     Sinterung)     nach dem Absaugen mit heissem Methylalko-      hol behandelt, wobei das     Diacetat    in Lösung  geht, während das Monoacetat in Form von  kleinen     warzenartigen    Kristallen zurück  bleibt.

   Das     Diacetat    wird dann durch Um  kristallisieren aus verdünntem Methanol wei  ter gereinigt. Es kristallisiert in weichen,  glänzenden fettigen Blättchen vom     Smp.    120  bis     121,5     .  



  Die physiologische Prüfung des     Diacetats     im     Allen-Doisy-Test    an der kastrierten Maus  ergibt bei subkutaner Verabreichung in wäs  seriger Lösung und sechsmaliger Untertei  lung einen Wirkungswert von 10 Millionen  M. E. pro g.

    Cxegensta.nd <SEP> of the present <SEP> invention <SEP> is
<tb> (in <SEP> - \ "find out <SEP> for the <SEP> production <SEP> of an <SEP> acylated <SEP> dihydrofollicle hormone, <SEP> which <SEP> thereby marks <SEP> e <SEP> is, <SEP> that <SEP> man <SEP> dihydrofollicle hormone <SEP> from <SEP> Smp. <SEP> 174 '<SEP> C <SEP> with <SEP> a <SEP> aeety licensed <SEP> agent <SEP> treated.
<tb> The <SEP> new <SEP> connection, <SEP> the <SEP> Diacetyldi h \ -cli-ofollil @ elliormon, <SEP> the <SEP> as a <SEP> drug

  . <SEP> shiny, <SEP> greasy <SEP> leaflets <SEP> from
<tb> Snip. <SEP> 1.20 <SEP> to <SEP> 121 <SEP> <SEP> C.
<tb> Next to <SEP> this <SEP> connection <SEP> is created. <SEP> at
<tb> the <SEP> procedure <SEP> nor <SEP> a <SEP> monoacetate <SEP> from
<tb> Sinli. <SEP>? 10 <SEP> to <SEP> \? 13 <SEP> <SEP> C.
<tb> <I>. Example: </I>
<tb> 1 <SEP> g <SEP> I) ihyd <SEP> rofollicular hormone <SEP> front <SEP> enamel punlit <SEP> <B> 172 </B> <SEP> to <SEP> <B> 1, 73 </B> <SEP> <SEP> <SEP> is dissolved in <SEP> a little <SEP> pure vinegar and 100% of a commercially available glacial acetic acid / hydrogen bromide mixture is poured over the solution while cooling with ice.

   The reaction solution initially takes on a golden yellow color. which gradually deepens. After standing for about two days, the reaction solution, which is now completely clear and no longer contains any traces of undissolved crystals, is poured into about 500 cm2 of ice water. The unusual white one. flaky precipitate is absorbed in ether. shake the ethereal solution one after the other with 5% aqueous solo solution and water, then dry and steam it off.

   The remaining consistent oily residue shows in concentrated sulfuric acid solution, in contrast to the starting material, which when dissolved in it fluoresces bright blue, under the analysis quartz lamp a purely golden yellow color and fluorescence.



  This oily product is precipitated from methyl alcoholic solution with water to separate the mono- and diacetyl dihydrofollicle hormone contained in it and the crystal cake obtained (melting point 173 to 174 'after gradual previous sintering) after Treated with suction with hot methyl alcohol, the diacetate going into solution, while the monoacetate remains in the form of small wart-like crystals.

   The diacetate is then purified further by recrystallization from dilute methanol. It crystallizes in soft, shiny, fatty flakes with a melting point of 120 to 121.5.



  The physiological test of the diacetate in the Allen-Doisy test on the castrated mouse, when administered subcutaneously in aqueous solution and subdivided six times, results in an activity value of 10 million M.U. per g.
