Verfahren zu dessen Herstellung und Arzneimittel, bestehend aus dieser Verbindung und üblichen Hilfs- und Trägerstoffen.Process for its production and pharmaceuticals, consisting of this compound and usual auxiliary and carriers.
Es wurde gefunden, daß dieses Dinicotinat des Thiamindisulfids in an sich bekannter Weise durch Umsetzung von Thiamindisulfid mit Nicotinsäure in molaren Verhältnissen, gegebenenfalls in einem Lösungs- und Verdünnungsmittel, wie Alkoholen oder Wasser, bei gewöhnlicher oder erhöhter Temperatur erhalten wird. Das Thiamindisulfiddinicotinat bildet farblose Kristalle, die in Wasser leicht löslich sind und auch einen verminderten bitteren Geschmack gegenüber dem Ausgangsprodukt ergeben. Es ist wesentlich ungiftiger als Thiamindisulfid, ergibt hohe Blutspiegelwerte an Vitamin B1, zeigt sich verstärkt bei Avitaminosen wirksam, potenziert die therapeutische Wirkung der Analgetika und von sedativ wirktarnen Körpern und ergibt eine ausgezeichnete Wirkung bei experimentell erzeugten Leberverfettungen.It has been found that this dinicotinate of thiamine disulfide is obtained in a manner known per se by reacting thiamine disulfide with nicotinic acid in molar proportions, optionally in a solvent and diluent, such as alcohols or water, at normal or elevated temperature. The thiamine disulfide dinicotinate forms colorless crystals that are easily soluble in water and also result in a reduced bitter taste compared to the starting product. It is significantly less toxic than thiamine disulfide, results in high blood levels of vitamin B 1 , is more effective in avitaminoses, potentiates the therapeutic effect of analgesics and sedative bodies and has an excellent effect on experimentally produced fatty liver.
Es wurden zunächst die Toxizitätsdaten gegenüber den bekannten Vitamin-BpDerivaten gezeigt. Die Bestimmung der DL50 erfolgte nach Kärber an «veißen Mäusen in mg/kg.First of all, the toxicity data for the known vitamin Bp derivatives were shown. The DL 50 was determined according to Kärber on white mice in mg / kg.

Das erfindungsgemäße Dinicotinat des Thiamindisulfids ist also wesentlich weniger giftig a!s bekannte Vergleichssubstanzen. Die Gegenüberstellung der erhaltenen Blutspiegelwerte erfolgt in der nachstehenden Tabelle. Von jeder Substanz wurden IO -mg-Äquivalente Vitamin-BrHydrochlorid oral an Hauskaninchen pro 3 kg Durchschnittskörpergewicht verabreicht und die Blut-Thiaminspiegel ( %) festgehalten. The dinicotinate of thiamine disulfide according to the invention is therefore significantly less toxic than known comparison substances. The comparison of the blood level values obtained is made in the table below. 10 mg equivalents of vitamin B r hydrochloride of each substance were administered orally to domestic rabbits per 3 kg of average body weight, and the blood thiamine level ( %) was recorded.

Die erhaltenen Blutspiegelwerte sind somit dem Vitamin-Bi-Hydrochlorid weit überlegen, sind günstiger als gegenüber dem Thiamindisulfid selbst und nur wenig niedriger als die mit Ο,Ο'-Dibenzoylthiamindisulfid, also einem Thiamin-disulfid-ester, erreichbaren. Sie sind somit für ein Vitamin-B,-Salz überraschend hoch.The blood level values obtained are thus far superior to the vitamin bi-hydrochloride and are cheaper than compared to the thiamine disulfide itself and only slightly lower than that with Ο, Ο'-dibenzoylthiamine disulfide, so a thiamine disulfide ester, achievable. You are therefore in favor of a vitamin B salt surprisingly high.

Das Üinicotinat des Thiamindisulfids hat also einen eindeutigen Einfluß auf die durch Tetrachlorkohlenstoff bedingte Leberverfettung.The Üinicotinat of thiamine disulphide has a clear influence on the fatty liver caused by carbon tetrachloride.
Das Dinicotinat des Thismindisulfids hat also neben einer guten Vitamin-B,-Wirksamkeit eine beachtliche Leberschutzwirkung und dient in Form von Tabletten, Dragees, Pulvern oder anderen konventionellen Zubereitungsformen als Arzneimittel.So the dinicotinate of thismin disulfide has in addition to a good vitamin B, effectiveness, a considerable liver protection effect and serves in form of tablets, coated tablets, powders or other conventional ones Forms of preparation as medicaments.
Die folgenden Beispiele erläutern die Herstellung der erfindungsgemäßen Verbindung:The following examples illustrate the preparation of the compound according to the invention:
28,6 g Thiamindisulfid werden in etwa 100 ml Methanol suspendiert. Dazu werden 12 g Nicotinsäure zugesetzt und alles 30 Minuten auf dem Wasserbade erwärmt. Es tritt Auflösung ein, und aisbald fällt das Nicotinat bereits während der Erwärmung aus. Man läßt erkalten, verdünnt zur Vervollständigung der Auskristallisation mit Äther, läßt 24 bis 30 Stunden stehen, si ugt die Kristalle ab und wäscht mit Äther nach, Ausbeute etwa 39 g.28.6 g of thiamine disulfide are in about 100 ml Suspended methanol. To this, 12 g of nicotinic acid are added and everything is placed on the water bath for 30 minutes warmed up. Dissolution occurs and the nicotinate soon falls during the warming up the end. Allow to cool, dilute with ether to complete the crystallization, leave 24 to Stand for 30 hours, suck off the crystals and wash with ether after, yield about 39 g.
