<Desc/Clms Page number 1>
la présente invention, à la réalisation de laquelle ont participé MM. Paul GAILLIOT et Jean ROBERT, concerne un nouveau sel de choline, à savoir l'ascorbate de choline, ainsi que son procédé de préparation.
On sait que 1'acide ascorbique donne facilement des sels métalliques ou des esters. Dans le cas de la choline .on a déjà décrit la préparation d'un ester par action de 2 molécules de chlorure de choline en présence d'acide chlorhydrique, ou

Il a maintenant été trouvé que, dans certaines condi- tions différentes des précédentes, l'acide ascorbique et la
<Desc/Clms Page number 2>
choline sont capables de réagir en proportions équimoléculairs en donnant un sel d'ammonium quaternaire. Ce sel a pour formule présumée:
EMI2.1
Le nouveau sel peut être obtenu par action de l'acide ascorbique sur la choline-base. Les réactifs sont utilisés en proportions équimoléculaires ou en léger excès de l'un par rapport à l'autre. La réaction est effectuée de préférence dans un milieu dans lequel les produits de départ sont solubles, et par exemple dans un alcool à bas poids moléculaire, dans un milieu hydroalcoolique ou plus simplement dans l'eau.
Après dissolution des réactifs, on peut évaporer le solvant, de préférence en atmosphère inerte et sous pression réduite, et obtenir ainsi l'ascorbate de choline. La réaction peut être effectuée à la température ordinaire, mais il est généralement avantageux de chauffer légèrement pour faciliter la dissolution des réactifs ou l'évaporation du solvant.- On peut également ajouter à la solution un composé qui diminue la solubilité du sel d'ammonium quaternaire; le sel ainsi précipité est sépara des eaux-mères par exemple par filtration ou décantation.
Le produit ainsi obtenu est suffisamment pur pour être utilisé tel quel dans la plupart des cas. On peut cependant le purifier davantage, par exemple par cristallisation dans un sol- vant ou par dissolution dans un solvant approprié suivie d'une précipitation à l'aide d'un composé qui en diminue la solubilité.
Le sel d'ammonium quaternaire obtenu suivant l'inven- tion possède des propriétés pharmacodynamiques précieuses qui en
<Desc/Clms Page number 3>
permettent l'utilisation en thérapeutique humaine et vétérinaire.
Il peut notamment être utilisé comme agent hépatoprotecteur.
L'exemple suivant, donné à titre non limitatif, montre comment l'invention peut être mise en pratique.
EXEMPLE.-
On dissout sous une atmosphère d'azote 35,2 g d'acide ascorbique dans 80,4 cm3 de solution aaueuse de choline-base à 30,1%. Après distillation de l'eau sous pression réduite d'azote vers 30 , on obtient une huile visqueuse (60 g) que l'on dissout vers 50 dans 180 cm3 de méthanol. On ajoute 350 cm3 d'éthanol, sépare le précipité formé et le sèche à froid sons vide en pré- sence d'acide sulfurique pendant 48 heures. On obtient ainsi 37 g d'ascorbate de choline fondant à 130-132 (Kofler).

the present invention, in the realization of which participated MM. Paul GAILLIOT and Jean ROBERT, concerns a new choline salt, namely choline ascorbate, as well as its preparation process.
It is known that ascorbic acid readily gives metal salts or esters. In the case of choline, we have already described the preparation of an ester by the action of 2 molecules of choline chloride in the presence of hydrochloric acid, or

$ 12 2 (19.7b ..
It has now been found that, under certain conditions different from the preceding ones, ascorbic acid and
<Desc / Clms Page number 2>
choline are able to react in equimolecular proportions to give a quaternary ammonium salt. This salt has the assumed formula:
EMI2.1
The new salt can be obtained by the action of ascorbic acid on the choline base. The reagents are used in equimolecular proportions or in slight excess of one relative to the other. The reaction is preferably carried out in a medium in which the starting products are soluble, for example in a low molecular weight alcohol, in a hydroalcoholic medium or more simply in water.
After dissolving the reagents, the solvent can be evaporated off, preferably in an inert atmosphere and under reduced pressure, and thus obtain choline ascorbate. The reaction can be carried out at room temperature, but it is generally advantageous to heat slightly to facilitate the dissolution of the reagents or the evaporation of the solvent. A compound can also be added to the solution which decreases the solubility of the ammonium salt quaternary; the salt thus precipitated is separated from the mother liquors, for example by filtration or decantation.
The product thus obtained is sufficiently pure to be used as it is in most cases. It can, however, be further purified, for example by crystallization from a solvent or by dissolution in a suitable solvent followed by precipitation with the aid of a compound which decreases its solubility.
The quaternary ammonium salt obtained according to the invention has valuable pharmacodynamic properties which make it
<Desc / Clms Page number 3>
allow use in human and veterinary therapy.
It can in particular be used as a hepatoprotective agent.
The following example, given without limitation, shows how the invention can be put into practice.
EXAMPLE.-
35.2 g of ascorbic acid are dissolved under an atmosphere of nitrogen in 80.4 cm 3 of aaueuse solution of choline-base at 30.1%. After distillation of the water under reduced nitrogen pressure at around 30, a viscous oil (60 g) is obtained which is dissolved at around 50 in 180 cm 3 of methanol. 350 cm3 of ethanol are added, the precipitate formed is separated off and dried under cold vacuum in the presence of sulfuric acid for 48 hours. 37 g of choline ascorbate, melting point 130-132 (Kofler), are thus obtained.
