Die vorliegende Anmeldung betrifft Kreatin-ascorbate und deren Herstellung, wobei es sich um wasserfreie oder wasserhaltige Salze der Ascorbinsäure mit Kreatin und Mischungen dieser Salze mit Kreatin oder Ascorbinsäure handelt.The present application relates to creatine ascorbates and their preparation, which are anhydrous or water-containing salts of ascorbic acid with creatine and mixtures of these salts with creatine or ascorbic acid.
Ascorbinsäure (L-( -t- )-Ascorbinsäure, Vitamin C, L-3-Keto-threo-2- hexuronsäure-Hacton, (R)-5-[(S)-1 ,2-Dihydroxy-ethyl]-3,4-dihydroxy-5H- furan-2-on) ist ein wesentlicher Nahrungsbestandteil zur Erhaltung der menschlichen Gesundheit. Es ist bekannt, daß die Ascorbinsäure oder deren Salze (Ascorbate) wertvolle physiologische, prophylaktische und therapeutische Eigenschaften für die Behandlung von verschiedenen Krankheiten besitzen. Seit der Entdeckung der schwersten Vitamin C- Mangelerkrankung, dem Skorbut und dessen Heilung durch Ascorbinsäure, sind viele interessante Wirkungen dieser Verbindung beschrieben worden.Ascorbic acid (L- (-t-) ascorbic acid, vitamin C, L-3-keto-threo-2-hexuronic acid hactone, (R) -5 - [(S) -1, 2-dihydroxy-ethyl] -3 , 4-dihydroxy-5H-furan-2-one) is an essential nutritional component for maintaining human health.

Die wichtigste Eigenschaft der Ascorbinsäure ist die reversible Oxidation zur Dehydro-L-ascorbinsäure, welche entscheidende Bedeutung für die physiologische Wirkung als Antioxidans hat. Zusammen mit anderen Antioxidantien, wie Carotinen, Glutathionen und Vitamin E wirkt Ascorbinsäure als Fänger für freie Radikale und oxidierende Sauerstoffspezies, Des weiteren vermag Ascorbinsäure das Vitamin E zu regenerieren. Die antioxidierende Wirkung von Ascorbinsäure führt zur Aktivierung des Immunsystems und senkt das Krebsrisiko. Ascorbinsäure beeinflußt den Cholesterin-Stoffwechsel in positiver Weise, was zu einer Verminderung von Gefäß- und besonders Herzgefäßerkrankungen führt. Wichtig sind auch die Funktionen der Ascorbinsäure als Enzymstimulans oder Cofaktor von Oxygenasen, welche u.a. die Synthese von Dopamin und Carnitin bewirken. Vitamin C wird außerdem bei der Behandlung von Anämien empfohlen, da es die Eisenresorption aus der Nahrung begünstigt (siehe Ullmann's Encyclopedia of Industrial Chemistry, 5th ed., 1 996 Vol. A27, p. 547-559) .The most important property of ascorbic acid is the reversible oxidation to dehydro-L-ascorbic acid, which is of crucial importance for the physiological effect as an antioxidant. Together with other antioxidants such as carotenes, glutathione and vitamin E, ascorbic acid acts as a scavenger for free radicals and oxidizing oxygen species.

Kreatin kommt im Muskel- und Nervengewebe (besonders im ZNS) vor und stellt in Form seines Stoffwechselfolgeprodukts, dem Phosphokreatin, eine Energiereserve des Muskels und des Gehirns dar. Im Nerven- und Herzmuskelgewebe scheint Kreatin eine prophylaktische und therapeutische Wirkung bei Ischämien zu besitzen, wie sie z.B. durch Infarktgeschehen oder prae- und perinatale Sauerstoffdefizitzustände auftreten.Creatine is found in muscle and nerve tissue (especially in the CNS) and, in the form of its metabolic secondary product, phosphocreatine, represents an energy reserve for the muscle and brain. In nerve and cardiac muscle tissue, creatine appears to have a prophylactic and therapeutic effect in ischemia, such as you eg due to infarction or pre- and perinatal oxygen deficit states.
Kreatin ist nicht nur eine körpereigene Substanz und ein wertvolles Nahrungsergänzungsmittel, sondern besitzt auch wertvolle therapeutische Eigenschaften. Kreatin ist seit über hundert Jahren als Muskelsubstanz bekannt, wobei es dem Muskel als Energiequelle dient. In einer Reihe von wissenschaftlichen Arbeiten wurde gezeigt, daß die Einnahme von Kreatin zu einer Steigerung der Muskelmasse und Muskelleistung führen kann.Creatine is not only an endogenous substance and a valuable nutritional supplement, but also has valuable therapeutic properties. Creatine has been known as a muscle substance for over a hundred years, using the muscle as a source of energy. A number of scientific studies have shown that taking creatine can lead to an increase in muscle mass and muscle performance.
Es gibt auch wissenschaftliche Erkenntnisse, daß die Bauchspeicheldrüse unter Einfluß von Kreatin vermehrt Insulin freisetzt. Insulin fördert die Aufnahme von Glucose und Aminosäuren in die Muskelzelle und regt die Proteinsynthese an. Insulin vermindert auch die Protein-Abbaurate.There is also scientific evidence that the pancreas releases more insulin under the influence of creatine. Insulin promotes the absorption of glucose and amino acids in the muscle cell and stimulates protein synthesis. Insulin also reduces the rate of protein breakdown.
Ein prophylaktischer, therapeutischer oder diätetischer Einsatz von Kreatin in den unterschiedlichsten Applikationsformen (oral, intravenös u.a.) setzt eine hohe Bioverfügbarkeit und damit eine gute Wasserlöslichkeit voraus. Diese ist für Kreatin, das als Aminosäurederivat in Form eines inneren Salzes vorliegt, nicht in ausreichendem Maße gegeben. Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, Formen von Kreatin zu entwickeln, die physiologisch besonders wertvoll sind und gleichzeitig eine gute Wasserlöslichkeit und ausreichende Lagerstabilität besitzen.The prophylactic, therapeutic or dietary use of creatine in a wide variety of application forms (oral, intravenous, etc.) requires high bioavailability and therefore good water solubility. This is not sufficient for creatine, which is an amino acid derivative in the form of an inner salt. The object of the present invention was therefore to develop forms of creatine which are particularly valuable physiologically and at the same time have good water solubility and adequate storage stability.
Diese Aufgabe wurde erfindungsgemäß durch die Bereitstellung von Kreatin- ascorbaten der Formel (I)This object was achieved according to the invention by providing creatine ascorbates of the formula (I)

In den Verbindungen der Formel (I) kann - entsprechend den stöchiome- trischen Erfordernissen - Kreatin in ungeladener Form oder als Kation und Ascorbat als Ascorbinsäure oder als Anion vorliegen.In accordance with the stoichiometric requirements, creatine can be present in the compounds of the formula (I) in an uncharged form or as a cation and ascorbate as ascorbic acid or as an anion.
Es hat sich nämlich überraschenderweise gezeigt, daß die erfindungsgemäßen Kreatin-ascorbate eine gute Lagerstabilität aufweisen, obwohl sich die bekannten Salze des Kreatins unter Bildung von Kreatinin zersetzen. Da Kreatin als inneres Salz vorliegt und nur eine schwache Base darstellt, konnte nicht damit gerechnet werden, daß man stabile Kreatinsalze mit aciden Enolen herstellen kann. Entsprechend dem Stand der Technik sind nämlich bislang nur Kreatinsalze von starken Di- und Tricarbonsäuren bekannt (vgl. WO 96/04 240), wobei jedoch stark saure Hydrogensalze gebildet werden. Die erfindungsgemäßen Kreatin-ascorbate der allgemeinen Formel (I) enthalten das physiologisch besonders wertvolle Kreatin-Kation der Formel (II) und das Ascorbat-Anion der Formel (III)Surprisingly, it has been shown that the creatine ascorbates according to the invention have good storage stability, although the known salts of creatine decompose to form creatinine. Since creatine is present as an inner salt and is only a weak base, it could not be expected that stable creatine salts can be produced with acidic enols. According to the state of the art, only creatine salts of strong di- and tricarboxylic acids have so far been known (cf. WO 96/04 240), but strongly acidic hydrogen salts are formed. The creatine ascorbates of the general formula (I) according to the invention contain the physiologically particularly valuable creatine cation of the formula (II) and the ascorbate anion of the formula (III)

Die erfindungsgemäßen Kreatin-ascorbate umfassen Salze, die das Kreatin- Kation und das Ascorbat-Anion vorzugsweise im Molverhältnis 1 : 1 oder annähernd im Molverhältnis 1 : 1 enthalten. Die erfindungsgemäßen Kreatin-ascorbate können darüber hinaus auch Mischungen dieser Salze mit Kreatin oder Ascorbinsäure darstellen.The creatine ascorbates according to the invention comprise salts which contain the creatine cation and the ascorbate anion preferably in a molar ratio of 1: 1 or approximately in a molar ratio of 1: 1. The creatine ascorbates according to the invention can also be mixtures of these salts with creatine or ascorbic acid.
Die Herstellung der erfindungsgemäßen Kreatin-ascorbate kann durch relativ einfache Umsetzung von Kreatin mit Ascorbinsäure im Temperaturberich von -10 bis 90 °C, vorzugsweise im Temperaturberich von 10 bis 30 °C, durchgeführt werden. Hierbei werden Kreatin und Ascorbinsäure im Molverhältnis von 100 : 1 bis 1 : 100 und vorzugsweise 5 : 1 bis 1 : 5 umgesetzt. Kreatin kann hierbei in wasserfreier Form als Monohydrat oder als feuchtes Produkt verwendet werden. Die Ascorbinsäure kann als wasserfreie Säure oder in Form einer wäßrigen Lösung eingesetzt werden.The creatine ascorbates according to the invention can be prepared by relatively simple reaction of creatine with ascorbic acid in the temperature range from -10 to 90 ° C., preferably in the temperature range from 10 to 30 ° C. Here, creatine and ascorbic acid are reacted in a molar ratio of 100: 1 to 1: 100 and preferably 5: 1 to 1: 5. Creatine can be used in anhydrous form as a monohydrate or as a moist product. The ascorbic acid can be used as an anhydrous acid or in the form of an aqueous solution.
Die Umsetzung kann in Abwesenheit oder in Gegenwart eines Löse- oder Verdünnungsmittels durchgeführt werden, wobei als Löse- oder Verdünnungsmittel eine breite Palette von organischen Lösemitteln geeignet sind . Bevorzugt werden Alkohole (wie Methanol, Ethanol, Isopropanol, Cyclohexanol), Ether (wie Diethylether, Tetrahydrofuran, 1 ,4-Dioxan, Ethylendimethylether), Ketone (wie Aceton, Methylethylketon, Cyclohexanon) oder Ester (wie Essigsäuremethylester, Essigsäureethylester, Ameisensäureethylester) oder aliphatische (Pentan, Hexan, Cyclohexan) sowie aromatische Kohlenwasserstoffe (Toluol) oder Mischungen davon verwendet. Die Umsetzung kann hierbei in den bekannten verfahrenstechnischen Apparaten wie in Mischern, Schaufeltrocknern und Rührbehältern erfolgen.The reaction can be carried out in the absence or in the presence of a solvent or diluent, a wide range of organic solvents being suitable as the solvent or diluent.

The reaction can be carried out in the known process engineering apparatus such as in mixers, paddle dryers and stirred tanks.
Die Kristallwasser-haltigen Kreatin-ascorbate sind durch Zusatz von Wasser während oder nach der Umsetzung von Ascorbinsäure mit Kreatin oder/und durch Verwendung von wäßrigem Kreatin oder/und wäßriger Ascorbinsäure erhältlich. Im Rahmen der vorliegenden Erfindung ist es auch möglich, bei oder nach der Herstellung noch andere Stoffe wie pharmazeutische Formulierungshilfsmittel, Vitamine, Mineralstoffe, Spurenelemente, Kohlenhydrate wie Glucose, Dextrose, Maltose oder Aminosäuren wie L- Carnitin oder andere Nahrungsergänzungsmittel zuzusetzen.The water of crystalline creatine ascorbates can be obtained by adding water during or after the reaction of ascorbic acid with creatine or / and by using aqueous creatine and / or aqueous ascorbic acid. In the context of the present invention, it is also possible to add other substances such as pharmaceutical formulation auxiliaries, vitamins, minerals, trace elements, carbohydrates such as glucose, dextrose, maltose or amino acids such as L-carnitine or other nutritional supplements during or after production.
Ein Gegenstand der Erfindung sind somit auch physiologisch verträgliche Zusammensetzungen, die Kreatin-ascorbate zusammen mit mindestens einer weiteren physiologisch verträglichen Substanz ausgewählt aus der Gruppe umfassend pharmazeutische Hilfs- oder Trägerstoffe, Vitamine, M i n e ra l stoff e , Ko h len hyd rate , Ami nosä u ren o d er a n d e re Nahrungsergänzungsmittel enthalten.The invention thus also relates to physiologically compatible compositions which contain creatine ascorbates together with at least one further physiologically compatible substance selected from the group comprising pharmaceutical auxiliaries or carriers, vitamins, minerals, colohydrates, ami nosä u ren or other food supplements.
Aufgrund ihrer wertvollen physiologischen Eigenschaften, ihrer hohen Lagerstabilität sowie guten Wasserlöslichkeit und hohen Bioverfügbarkeit eignen sich die erfindungsgemäßen Kreatin-ascorbate hervorragend für therapeutische Anwendungen in der Medizin und als Nahrungser- gänzungsmittelzusätze, wobei diese nicht nur die bekannten wertvollen biologischen und medizinischen Eigenschaften von Ascorbaten und von Kreatin besitzen, sondern darüber hinaus überraschenderweise noch deutliche synergistische Effekte aufweisen.Because of their valuable physiological properties, their high storage stability and good water solubility and high bioavailability, the creatine ascorbates according to the invention are outstandingly suitable for therapeutic applications in medicine and as food supplement additives, these not only having the known valuable biological and medical properties of ascorbates and of Possess creatine, but also surprisingly have clear synergistic effects.
