Definitions

  • 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.
  • 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. It is known that ascorbic acid or its salts (ascorbates) have valuable physiological, prophylactic and therapeutic properties for the treatment of various diseases. Since the discovery of the most serious vitamin C deficiency disease, scurvy and its healing by ascorbic acid, many interesting effects of this compound have been described.
  • ascorbic acid 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. Furthermore, ascorbic acid can regenerate vitamin E. The antioxidant effect of ascorbic acid activates the immune system and reduces the risk of cancer. Ascorbic acid has a positive effect on cholesterol metabolism, which leads to a reduction in vascular and especially cardiovascular diseases. Also important are the functions of ascorbic acid as an enzyme stimulant or cofactor of oxygenases, which among other things cause the synthesis of dopamine and carnitine. Vitamin C is also recommended in the treatment of anemia because it promotes iron absorption from food (see Ullmann's Encyclopedia of Industrial Chemistry, 5 th ed., 1 996 vol. A27, p. 547-559).
  • 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.
  • 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.
  • 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.
  • 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.
  • the prophylactic, therapeutic or dietary use of creatine in a wide variety of application forms 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.
  • z 1 to 100, preferably 1 to 5
  • y 1 to 100, preferably 1 to 5
  • n 0 to 20, preferably 0 to 2.
  • 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.
  • 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)
  • 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.
  • 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.
  • 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.
  • 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.
  • Alcohols such as methanol, ethanol, isopropanol, Cyclohexanol
  • ethers such as diethyl ether, tetrahydrofuran, 1,4-dioxane, ethylenedimethyl ether
  • ketones such as acetone, methyl ethyl ketone, cyclohexanone
  • esters such as methyl acetate, ethyl acetate, ethyl formate
  • the reaction can be carried out in the known process engineering apparatus such as in mixers, paddle dryers and stirred tanks.
  • 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.
  • 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.
  • 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.
  • 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.
  • the creatine ascorbates according to the invention are particularly suitable for increasing muscle build-up and strength in the sports sector, for the prophylaxis and treatment of oxygen deficit conditions (ischemia) and immune stimulation in the health sector, for the treatment of muscular disorders and as a food supplement.
  • ischemia oxygen deficit conditions
  • immune stimulation in the health sector, for the treatment of muscular disorders and as a food supplement.

Abstract

L'invention porte sur des créatine-ascorbates de formule générale (I), à savoir (créatine)z(ascorbate)y(H2O)n, où z = 1 à 100, y = 1 à 100 et n = 0 à 20. Ces créatine-ascorbates, qui se préparent en mettant de manière relativement simple de la créatine à réagir avec de l'acide ascorbique, peuvent s'utiliser pour consolider la musculature et accroître la force dans le domaine sportif, pour la prévention et le traitement d'états oxygénodéficitaires (ischémie), pour la stimulation immunitaire dans le domaine de la santé, pour le traitement d'atrophies musculaires et comme additif alimentaire complémentaire.
