Description

  

  Verfahren zur Darstellung einer therapeutisch wertvollen Verbindung.    <B>E</B>s wurde gefunden, dass man zu neuen,  therapeutisch wertvollen Verbindungen ge  langen kann, wenn man     Äthanolamine    mit  solchen kernjodierten aromatischen,     aroma-          tisch-alipha.tischen        bezw.        heterocyclischen          Sulfon-        bezw.        Carbonsäuren,    welche die sau  ren Gruppen direkt oder mittelst Kohlen  stoff an     Kernkohlenstoffatome    gebunden  enthalten, in üblicher Weise nach Art der  Salzbildung vereinigt.  



  Die gemäss vorliegender Erfindung her  gestellten Verbindungen sind im allgemeinen  leicht löslich in Wasser und bilden zur In  jektion geeignete Lösungen. Das Vorhan  densein des     Äthanolaminrestes    ruft eine un  erwartete Steigerung des therapeutischen  Effektes der damit vereinigten     kernjodier-          ten    Verbindung hervor,     bezw.    verleiht den  selben neue therapeutische Wirkungen.  



  Zur Ausführung des Verfahrens kann  man sowohl das     14Tonoäthanolamin,    wie auch  das     Di-und        Triäthanolamin    verwenden. Ver  bindungen, die Säurecharakter besitzen und  sich für das vorliegende Verfahren eignen,    sind die kernjodierten aromatischen,     aroma-          tisch-aliphatischen    und     heterocyclischen    Ver  bindungen, die die salzbildende Gruppe oder  Gruppen im Kern oder in einer     aliphatischen     Seitenkette enthalten.

   Solche Verbindungen  sind zum Beispiel die     Jodbenzoesäure    und  die     Jodbenzolsulfosäuren,    welche noch wei  tere     Substituenten    tragen können,     wie    zum  Beispiel die     Jodaminobenzoesäure,    die     Jod-          acetylsalicylsäure,        Jodogybenzolsulfosäure;

       es ist aber nicht notwendig, dass die     Car-          boxylgru.ppe    an den     Benzolkern    gebunden  ist, da auch Verbindungen, wie zum Beispiel  das     Dijodtyrosin,    zur Ausführung des vor  liegenden Verfahrens geeignet sind und zu  wertvollen Derivaten führen.  



  Als     Verbindungen    der     Naphtalinreihe     werden die kernjodierten     Naphtalinsulfo-          u.nd        -carbonsäuren,    die noch weitere     Substi-          tuenten    tragen können, verwendet. Es ge  lingt zum Beispiel, aus den therapeutisch  schon sehr wertvollen     Jodnaphtolsulfosäuren     sehr aktive Präparate der hier beanspruch  ten Zusammensetzung herzustellen.

   Als De-           rivate    der     heterocyclischen    Reihe können       Pyridin-    und     Chinolinearbon-    und     -sulfon-          säuren,    wie zum Beispiel     Jodogychinolin-          sulfosäuren,    verwendet werden.  



  Das vorliegende Verfahren     betrifft        nun     die Herstellung des     Monoäthanolaminsalzes     der     3,5-Dijod-p-aminobenzoesäure    und ist  dadurch     gekennzeichnet,    dass man     3,5-Dijod-          p-aminobenzoesäure    mit     Monoäthanolamin     umsetzt.

           Beispiel       Zu einer Lösung von 8     gr        3,5-Dijod-p-          aminobenzoesäure        in    200 cm' Methylalkohol,  werden bei Siedetemperatur 8     cm3    einer vier  fach normalen alkoholischen Lösung von       Monoäthanolamin    zugesetzt und das     Reak-          tionsgemiseh    mit 1 Liter Äther versetzt,  wobei die neue Verbindung auskristallisiert.

  Method of creating a therapeutically valuable compound. It has been found that new, therapeutically valuable compounds can be found if ethanolamines are mixed with such nuclear iodized aromatic, aromatic-aliphatic or aliphatic tables. heterocyclic sulfone or. Carboxylic acids which contain the acidic groups bound directly or by means of carbon to core carbon atoms, combined in the usual way in the manner of salt formation.



  The compounds produced according to the present invention are generally readily soluble in water and form suitable solutions for injection. The presence of the ethanolamine residue causes an unexpected increase in the therapeutic effect of the nuclear iodized compound associated with it, respectively. gives the same new therapeutic effects.



  To carry out the process, both the 14tonoethanolamine and the di- and triethanolamine can be used. Compounds which have acid character and are suitable for the present process are the nuclear iodized aromatic, aromatic-aliphatic and heterocyclic compounds which contain the salt-forming group or groups in the core or in an aliphatic side chain.

   Such compounds are, for example, iodobenzoic acid and iodobenzenesulfonic acids, which can also carry further substituents, such as, for example, iodoaminobenzoic acid, iodoacetylsalicylic acid, iodogybenzenesulfonic acid;

       however, it is not necessary that the carboxyl group is bound to the benzene nucleus, since compounds such as diiodotyrosine are also suitable for carrying out the present process and lead to valuable derivatives.



  As compounds of the naphthalene series, the nuclear iodized naphthalene sulfo- and carboxylic acids, which can also carry further substituents, are used. It is possible, for example, to produce very active preparations of the composition claimed here from the therapeutically very valuable iodonaphthol sulfonic acids.

   As derivatives of the heterocyclic series, pyridine and quinoline carbonic and sulfonic acids, such as, for example, iodogyquinoline sulfonic acids, can be used.



  The present process relates to the preparation of the monoethanolamine salt of 3,5-diiodo-p-aminobenzoic acid and is characterized in that 3,5-diiodo-p-aminobenzoic acid is reacted with monoethanolamine.

           EXAMPLE To a solution of 8 g of 3,5-diiodo-p-aminobenzoic acid in 200 cm of methyl alcohol, 8 cm3 of a four times normal alcoholic solution of monoethanolamine are added at the boiling point and 1 liter of ether is added to the reaction mixture Compound crystallized out.
