Description

  

      Verfahren        zur        Gewinnung    von     Lysergsäure-Derivaten       Das Hauptpatent Nr. 468 465 beschreibt ein Ver  fahren zur     Gewinnung    von     6-Methyl-Aa,

  9-ergalen-          8-carbonsäure    durch     saprophytische    Züchtung eines  neuen     konidienbildenden    Pilzstammes der     Species        Cla-          viceps        paspali    Stevens et Hall in     Submerskultur        resp.          Fermenterkultur    und anschliessende Extraktion der       6-Methyl-Qe@9-ergolen-8-carbonsäure    aus dem Kultur  filtrat auf an sich bekannte Weise.

   Dieser Pilz wurde  beim     United        States    Department of     Agriculture        (Nort-          liern        Utilisation    Research     and        Development    Division),       Peoria,        Ill.    hinterlegt und erhielt dort die Bezeichnung       NRRL    3080.  



  Es wurde nun gefunden, dass man aus diesem     Pilz-          stamm    durch Bestrahlung mit ultraviolettem Licht und  anschliessende Behandlung mit     Äthylenimin    auf an sich  bekannte Weise Mutanten gewinnen kann, die mehr       6-Methyl-Q8,9-ergolen-8-carbonsäure    zu bilden ver  mögen als der Ausgangsstamm.

       Eine    dieser Mutanten  wurde beim     United        States    Department of     Agriculture          (Northern        Utilisation    Research     and        Development    Divi  sion),     Peoria,        lll.    unter der Bezeichnung     NRRL    3167  deponiert.  



  Erfindungsgemäss kann man hierbei vorteilhafter  weise wie folgt verfahren:  Man suspendiert     Konidien    des Pilzstammes       NRRL    3080 in Wasser und verteilt diese Suspension  auf die     Agaroberfläche    einer mit     Malzagar    ausgegosse  nen     Petrischale.    Danach werden pro     Petrischale    ca.  1000 Sporen ausgesät.

   Die     Agaroberfläche    wird dann  mit ultraviolettem Licht bestrahlt, bis pro Platte nur  noch 5-10     Konidien    auskeimen; dieses entspricht einer       Abtötungsrate        von.        99-99,5        9/a    (Abstand von der Licht  quelle, z. B. Hanaulampe und Belichtungsdauer werden  in     Vorversuchen    empirisch ermittelt).

   Aus den überle  benden Sporen entstehen im Verlauf von 10-14 Tagen  bei 22      makroskopisch    sichtbare     Kolonien.        Diese    wer  den weiter     überimpft,    um auf die im Hauptpatent be  schriebene Weise Kulturen mit     Konidien    zu gewinnen.    Aus den so gewonnenen Mutanten werden mit  Hilfe von Züchtungsversuchen (z. B. in einer der im  Hauptpatent beschriebenen Kulturen) diejenigen  Stämme ausgewählt, die sich durch ein besonders  hohes     Alkaloidbildungsvermögen    auszeichnen und  einer weiteren     mutagenen    Behandlung mit Hilfe von       Äthylenimin    unterworfen.

   Hierfür werden die     Konidien     bei 24  während 2 Stunden     in        einer    1     %oigen        Äthylen-          iminlösung        suspendiert,        die    Sporen     mittels    eines       Membranfilters    von der Lösung getrennt, auf dem Fil  ter mit sterilem Wasser gewaschen und dann auf     Agar-          platten        ausgeimpft.    Bei dieser     Behandlung    beträgt die       Abtötungsrate    ca. 99 9/0.  



  Von den überlebenden Stämmen werden wiederum,  wie oben beschrieben, die Mutanten mit dem höchsten       Alkaloidbildungsvermögen    ausgewählt und gegebenen  falls noch 5-10 Male einer     mutagenen    Behandlung mit       Athylenimin    unterworfen.

   So erhält man beispielsweise  bei     6-facher    Wiederholung dieser Behandlung einen  besonders stark     alkaloidbildenden    Stamm, der beim       United        States    Department of     Agriculture        (Northern          Utilisation    Research     and        Development    Division),     Peo-          ria,   <B>111.</B> unter der Bezeichnung     NRRL    3167 deponiert  wurde.  



  Bei der Züchtung der Mutante     NRRL    3167 in der  im     Hauptpatentgesuch    beschriebenen Schüttelkultur  wird nach Aufarbeitung des Kulturfiltrates eine Aus  beute von 3330     mg/1    an Gesamtalkaloiden ermittelt;  davon sind 89     9/o        6-Methyl-A8,9-ergolen-8-carbonsäure     und     119/o        Clavinalkaloide.    In der im     Hauptpatentge-          such    beschriebenen     Fermenterkultur    produziert diese  Mutante 2480     mg/1    an Gesamtalkaloiden; davon 93 9/0       6-Methyl-/\8,11-ergolen-8-carbonsäure.  



      Process for the production of lysergic acid derivatives The main patent No. 468 465 describes a process for the production of 6-methyl-Aa,

  9-ergalen- 8-carboxylic acid by saprophytic breeding of a new conidia-forming fungal strain of the species Cla- viceps paspali Stevens et Hall in submerged culture, respectively. Fermenter culture and subsequent extraction of the 6-methyl-Qe @ 9-ergolen-8-carboxylic acid from the culture filtrate in a manner known per se.

   This fungus has been deposited with the United States Department of Agriculture (Northern Utilization Research and Development Division), Peoria, Ill., Where it was given the designation NRRL 3080.



  It has now been found that, by irradiation with ultraviolet light and subsequent treatment with ethylene imine, mutants capable of forming more 6-methyl-Q8,9-ergolen-8-carboxylic acid can be obtained from this fungal strain than the starting stem.

       One of these mutants was at the United States Department of Agriculture (Northern Utilization Research and Development Division), Peoria, III. deposited under the designation NRRL 3167.



  According to the invention, one can advantageously proceed as follows: Conidia of the fungal strain NRRL 3080 are suspended in water and this suspension is distributed on the agar surface of a Petri dish filled with malt agar. Then about 1000 spores are sown per Petri dish.

   The agar surface is then irradiated with ultraviolet light until only 5-10 conidia germinate per plate; this corresponds to a kill rate of. 99-99.5 9 / a (distance from the light source, e.g. Hanau lamp and exposure time are empirically determined in preliminary tests).

   The surviving spores gave rise to macroscopically visible colonies in 22 within 10-14 days. These who the further inoculated in order to win cultures with conidia in the manner described in the main patent. From the mutants obtained in this way, breeding experiments (e.g. in one of the cultures described in the main patent) are used to select those strains which are characterized by a particularly high alkaloid-forming capacity and are subjected to further mutagenic treatment with the aid of ethyleneimine.

   For this purpose, the conidia are suspended in a 1% ethylene imine solution for 2 hours at 24, the spores are separated from the solution using a membrane filter, washed on the filter with sterile water and then inoculated onto agar plates. With this treatment, the kill rate is approx. 99 9/0.



  From the surviving strains, as described above, the mutants with the highest alkaloid-forming capacity are again selected and, if necessary, subjected to a mutagenic treatment with ethyleneimine 5-10 times.

   For example, if this treatment is repeated 6 times, a particularly strong alkaloid-forming strain is obtained, which is available from the United States Department of Agriculture (Northern Utilization Research and Development Division), Peria, <B> 111. </B> under the name NRRL 3167 was deposited.



  When cultivating the mutant NRRL 3167 in the shaking culture described in the main patent application, a yield of 3330 mg / 1 total alkaloids is determined after processing the culture filtrate; 89% of these are 6-methyl-8,9-ergolen-8-carboxylic acid and 119% are clavine alkaloids. In the fermenter culture described in the main patent application, this mutant produces 2480 mg / l of total alkaloids; of which 93 9/0 6-methyl- / \ 8,11-ergolen-8-carboxylic acid.
